  • Assessment of Fruit Fly Infestation on Melon Manis Terengganu (Cucumis
           melo var. inodorus) at Different Fruit Ripening Stages

    • Authors: Nor Aminah Azizol Azeli, Salmah Mohamed, Nur Athiqah Md.Yusof
      Pages: 1 - 8
      Abstract: Cucumis melo var inodorus or known as Melon Manis Terengganu (MMT) is a new variety of rockmelon and has been developed and grown exclusively in Terengganu since 2015. However, pest infestations such as fruit flies have reduced melon production yields, and research on fruit flies is still poorly studied in this new variety. Therefore, this study was aimed to identify the fruit fly’s species infested MMT as well as to determine the infestation rate of fruit flies on MMT at different ripening stages. The infested MMT fruits were randomly collected for three consecutive weeks prior to harvest and each week was represented as unripe stage (Week 1), ripe stage (Week 2) and fully-ripe stage (Week 3). Each week, 10 fruit samples were brought to the laboratory and weighed individually before being placed in plastic containers. The fruits were reared until all larvae transformed into pupae for determination of infestation rates and emergence of adult fruit flies for species identification. A total of 232 of fruit flies adults emerged from 30 MMT fruit samples collected and all the flies were identified as Zeugodacus cucurbitae (previously known as Bactrocera cucurbitae).  Unripe stage fruits recorded the highest infestation rate of fruit flies at 28.24 ± 18.58 pupae/kg and followed by ripe stage at 24.47 ± 8.17 pupae/kg. Whilst the fully-ripe stage had the lowest infestation rate of flies at 13.5 ± 5.07 pupae/kg. However, no significant difference (P>0.05) of infestation rate was recorded among the different fruit stages. This study contributes new information on the fruit fly’s species that attack MMT and its infestation rate. Hence, these findings are expected to help better management of MMT fruit flies in the future.

  • Evaluation of Allelopathic Potential of Pluchea indica on Brassica
           chinensis and Zea mays

    • Authors: Muhammad Ridwan Salim, Wan Zateel Aieeda Wan Abdul Halim , Nornasuha Yusoff
      Pages: 9 - 16
      Abstract: Weeds have become one of the leading causes of crop production losses, including the cost of weed management, weed crop competition, and weed intervention with crop management practices. Moreover, herbicide use in agricultural systems is currently being debated due to the potential adverse effects on the environment and human health. The utilization of the allelopathic phenomenon is widely considered an alternative weed management strategy. However, allelopathic study of Pluchea indica plant was limited. P. indica is a flowering plant under family Asteraceae, locally known as Beluntas. Thus, this study was conducted to determine the allelopathic effects of the aqueous leaf extract of P. indica on the seedling growth of tested plant species and to investigate the effect of P. indica leaf debris on the growth of tested plant species. In this study, the allelopathic potential of P. indica leaves were investigated through petri dish bioassay and soil bioassay method. The two tested plant species were chosen for the bioassay: monocotyledonous; maize (Zea mays) and dicotyledonous; mustard (Brassica chinensis). These tested plant species were chosen for the experiment due to their known quick seedling growth behaviours and commonly used in allelopathic studies. The result showed that as the concentration of aqueous leaf extract increased, the inhibition percentage of the radicle length of B. chinensis and Z. mays were increased. However, stimulatory effect was observed on the radicle length of B. chinensis and Z. mays when 1.3%and 2.5% w/w  P. indica leaf debris were applied. Thus, aqueous leaf extract and leaf debris of P. indica have potential allelopathic effects on the growth of B. chinensis and Z. mays. Further studies need to be conducted on other bioassay species especially weed species, to elucidate the allelopathic potential of P. indica in weed control.

  • Nutritional Evaluation of Azolla pinnata and Azolla microphylla as Feed
           Supplements for Dairy Ruminants

    • Authors: Jia Yee Ting, Nurul Aini Kamaruddin, Siti Syahirah Safiah Mohamad
      Pages: 17 - 23
      Abstract: Azolla is an aquatic plant that has the potential to be used as animal feed due to its high nutritive value and very productive plant. Thus, the objectives of this study are to determine and compare the nutrient and mineral composition of Azolla pinnata and Azolla microphylla. A. pinnata and A. microphylla are aquatic plants that have a high potential to be introduced as a new alternative feed supplement to ruminants. Samples were collected at Ladang Lembah Kaprima Hulu Seladang, Tenox Agribusiness (M) Sdn Bhd, Kampung Seladang, Setiu, Terengganu. The collected samples were dried and ground before the samples were analysed by using proximate analysis and microwave digestion for Induced Coupled Plasma Optical Emission Spectrometer (ICP-OES). Six parameters were measured for the proximate analyses which were dry matter, ash, crude protein, ether extract, crude fibre and nitrogen-free extract. The mineral compositions were analyzed for the contents of copper, zinc, iron, calcium and manganese using the ICP-OES. The result shows that A. microphylla contains the highest protein and ether extract content compared to A. pinnata. As in mineral composition, A. pinnata and A. microphylla showed that there were significant differences (p < 0.05) between the two plants. This study revealed that A. microphylla is more suitable to be used as a supplement for dairy ruminants as it contains a more nutritive value in terms of higher crude protein and ether extract that are essential for the ruminant diet.

  • Study on Chemical Composition of Napier Pak Chong (Pennisetum purpureum x
           Pennisetum glaucum) Harvested at Different Growth Stages

    • Authors: Siti Syahirah Safiah Mohamad, Nurul Aini Kamaruddin, Jia Yee Ting
      Pages: 24 - 30
      Abstract: Napier Pak Chong is a new hybrid crossing Pennisetum purpureum and Pennisetum glaucum known as Pearl Millet Napier. The Napier Pak Chong grass has been introduced due to its high nutritional contents, particularly in terms of crude protein compared to other napier grass varieties. Therefore, the aims of this study were to determine the chemical composition of the Napier Pak Chong harvested at three different growth ages which are 45 days, 60 days and 75 days and to identify the best harvesting ages of the Napier Pak Chong grass. The samples were collected at Kaprima Hulu Seladang Valley Farm. Then, the samples were dried and ground before being analyzed using proximate analysis and mineral analysis using Induced Couple Plasma Optical Emission Spectrometry (ICP-OES). In the proximate analysis, the plant samples were analyzed to determine the percentage of moisture, ash, crude fibre (CF), crude protein (CP) and fat. For the mineral analysis, the samples were analyzed for magnesium, potassium, sodium, phosphorus and calcium. Results showed that the percentages of crude protein in the Napier Pak Chong grass decreased with increased harvesting ages meanwhile the crude fibre increased along with maturity. The percentage of crude protein is highest at 45 days which is 19.48%. The results also showed that the chemical compositions were highest at the early stage of harvesting, which is at 45 days. Thus, this study showed that the harvesting ages have an effect on the chemical composition of Napier Pak Chong grass.

  • Efficacy of Neem Oil (Azadirachta indica) and Clove Oil (Syzygium
           aromaticum) against Ear Mites in Rabbits (Oryctolagus cuniculus)

    • Authors: Nur Amilin Zulkepeli, Nur Athiqah Md Yusof
      Pages: 36 - 42
      Abstract: Ear mites are a common ectoparasite that causes a skin disease known as mange in rabbits. Its infestation will contribute to poor growth, decrease production performances and in severe cases, cause mortality. To date, chemical pesticides are still widely used to control rabbit mites, where long-term use will contribute to the evolution of mite resistance. Essential oils have become an alternative method due to their efficacy and safety. This study was aimed to determine the efficacy of clove oil and neem oil against rabbit ear mites. The rabbits were divided into four treatment groups: T1, T2 and T3 and T4, each having three rabbits. These groups were topically treated with ivermectin (control group), clove oil, neem oil, 50:50 of clove and neem oil respectively on days 0, 7, 14, 21 and 28. The number of mites was counted and recorded as post-treatment evaluations by microscopic examination of skin scrapings from each group. The number of mites were progressively decreased in T2, but fluctuated in T1, T3 and T4. The number of live mites for each treatment was not statistically different (p>0.05) between treatments for days 0, 7 and 21, but the number of mites was statistically different (p<0.05) between all treatments for days 14 and 28. T4 that was treated with both clove and neem oil showed the highest efficacy with 94% for day 14 post-treatment, while treatment with neem oil (T3) showed the highest efficacy (89.7%) for day 28 after treatment. The results revealed that the mixture of both oils was the most effective against rabbit ear mites, however comparing the two oils, neem was more effective than clove oil in controlling the mites.

  • Consumer Preferences for Imported Beef Meat Purchasing in Johor Bahru

    • Authors: Aiman Asyraf Jamaluddin, Nurul Aisyah Mohd Suhaimi
      Pages: 38 - 48
      Abstract: Meat consumption in Malaysia is increasing in the past decades. While local beef meat cannot meet the local demand, Malaysia government has to import beef meat in order to fulfil the local consumption. When it comes to imported beef meat for consumption, there are many factors that are involved before consumers decide to purchase, hence it is important to understand the relevance of customers preferences in imported beef meat purchase. This study aims to identify the level of consumers preferences for imported beef meat purchasing and to determine the most influential factors for the consumers when purchasing imported beef meat in Johor Bahru. This study adopts a conceptual framework, which includes perceived quality and quality que among Johor Bahru consumers. 100 respondents participated in this study through convenience sampling. A self-administered questionnaire was distributed through an online platform which is Google form. Descriptive analysis and factor analysis were used to analyse the data. Results showed that consumers preferred to buy imported beef meat with Halal logo. The other factors that influence imported beef meat preference are freshness and cleanliness. The outcomes of this study might help marketers to have a better understanding on consumers preferences when it comes to purchasing imported beef meat from retail outlets.

  • Needs for Terengganu Sweet Melon Growers for Quality Production using
           Fertigation System

    • Authors: Zanariah Mohd Nor, Intan Nur Mariam Abdullah, Siti Raba’ah Hamzah, Mohammad Moneruzzaman Khandaker, Nur Athiqah Md Yusof
      Pages: 49 - 63
      Abstract: The Terengganu government needs 100 more fertigation growers of Terengganu Sweet Melon (MMT), to meet the European market demand. Undocumented local growers' needs for MMT fertigation farming hinder the local government’s efforts to retain and attract new local growers. Hence, this study’s objective was to explore the needs of MMT growers using the fertigation system for quality production in Terengganu. This qualitative study used semi-structured interviews complemented with Participatory Research Appraisal (PRA) tools for data collection. Through purposive sampling, 13 MMT growers volunteered as the study informants. The thematic analysis of the semi-structured interviews extracted six themes on growers’ needs. Almost all growers acknowledged MMT has promising prospects for its high market price and cost-effective fertigation system for quality production. However, they expressed six needs to help retain and support MMT fertigation technology adoption for quality production. All growers received a lack of technical consultancy; thus, their top urgent need was the advisory services on the technical knowledge and skills on MMT, fertigation system, and pests and diseases controls. Lack of financial support was also their urgent need for financial assistance to initiate, operate and maintain the high-cost infrastructure of the fertigation farming system. Different roles of agricultural-related and financial institutions were crucial to support their need for professional development, resources, and fertigation farm upscaling. In conclusion, MMT fertigation growers identified six needs that must be addressed for quality production. Their major needs were the technical advisory services on MMT and fertigation system, and financial assistance. Thus, the Terengganu government may incorporate the study findings to formulate an attractive policy for relevant government and NGOs’ roles to provide the relevant extension and advisory services, professional development packages, and friendly resources aid for the advancement of existing growers and to solicit new growers' participation.

  • Effect of Osmotic Dehydration as a Pre -Treatment on Air Fried Sweet
           Potato (Ipomoea batatas) Chips

    • Authors: Wan Mohd Fadli Wan Mokhtar, Zi Yu Thow
      Pages: 64 - 73
      Abstract: Air frying is a modern frying technique that promises low oil content of fried products. However, the main limitation of air frying is that it requires a longer operating time than deep fat frying. Previous studies found that osmotic dehydration is beneficial as frying pre-treatment to improve the quality of fried products and reduce frying time, but to date, there is no study investigating its application in air frying. Therefore, this study aims to examine the effect of osmotic dehydration as pre-treatment on the quality of air-fried sweet potato chips. Sweet potatoes were cut into slices with the same thickness, and then soaked in distilled water, 5% sodium chloride solution, and 10% sodium chloride solution for one hour. The potato slices were then air fried at two temperatures: 160˚ and 180˚C for 3, 6, 9, 12, and 15 minutes. Then, moisture content, colour, texture, diameter shrinkage and thickness expansion were analysed. The moisture content of air fried chips decreased with the increasing of frying time. The osmo-dehydrated sample showed lower moisture content which could the reduce frying time from 12 mins to 9 mins at 160ºC. Osmo-dehydrated sweet potato slices produce paler chips, but the treatment preserved the red and yellow colour of the sample. Air fried sweet potatoes that were osmotically dehydrated samples shrank more in diameter than the control samples. The increased thickness of chips was caused by crust formation and the bubbles formed at the surface due to the barrier formed by the tight surface, resulting in vapour expansion inside the pores of the chips. The hardness of pre-treated chips increased significantly with decreasing moisture content. Using osmotic dehydration pre-treatment in the air frying process can yield promising results in less frying time and better retention in terms of red and yellow colour.

           Freeze Dried Goat Milk Yogurt Powder

    • Authors: Siti Nonazifah Mat Sarif, John Yew Huat Tang, Asmaliza Abd Ghani
      Pages: 74 - 84
      Abstract: Yogurt is a fermented milk product that has a semi-solid texture and has a short shelf life. It must be stored properly in temperature of 4ºC and below to prevent the microbial spoilage due to it high in moisture content and water activity. This study aimed to produce freeze dried goat milk yogurt powder with different percentage of honey and analyse the physicochemical as well as compare the microbial count of bacterial growth in fresh goat milk yogurt and reconstituted goat milk yogurt powder. The four formulations prepared were 6% of sugar (CY), 3% of honey with 3% of sugar (LHY), 4% of honey with 2% of sugar (MHY) and 6% of honey (HHY). The results showed each formulation has significant differences for the physicochemical analysis. The percentage of honey added into the yogurt was affected the pH value of the yogurt which have a range from pH 4.18 to 4.45. Meanwhile the results for colour analysis shown that the yellowness value of goat milk yogurt was increased as the percentage of honey added inside the yogurt was increased, as contributed by dark brown colour of honey. The bacterial survival in CY, LHY, MHY and HHY samples for fresh goat milk yogurt and reconstituted goat milk yogurt powder showed the significant different (p<0.05) with the range from 6.40 to 8.75 log cfu/ml and 5.79 to 8.07 log cfu/ml respectively. Therefore, it can be concluded that freeze drying was a suitable method to produce yogurt powder and LHY sample was the best formulation in producing the highest number of survival bacteria (log cfu/ml).

      Abstract: Anthropogenic activities are the main cause of water quality deterioration which causes severe impacts on aquatic animals and human health. Mud clams (Polymesoda expansa) mostly eaten by people in Southeast Asia especially Terengganu can be exposed to the heavy metal contamination because of their filter feeder behaviour. This study aims to determine the water quality index (WQI) and investigate the selected heavy metal (Cr, Ni, Cu, Zn, Pb) contamination using Lokan (Polymesoda expansa) as a bioindicator at Benting Lintang, Besut, Terengganu. Analysis of water quality parameters was conducted In-situ and Ex-situ which involves 3 stations along the Benting Lintang water body. The heavy metal analysis was determined by using the acid digestion method and ICP-OES. The statistical analysis ANOVA shows the p-value is less than 0.05 proved there are significant different of heavy metal in mud clams between wet and dry season. The water quality at all stations during wet and dry season categorized at class II except station 2 during dry season falls on class III. The class II water quality shows that recreational activities can be done at the study location while extensive treatment is required at the station 2 during dry season. Heavy metal accumulated in mud clams for Cr, Ni and Cu in both seasons still in permissible limit according to FDA (2007), FAO (1983) except Pb and Zn exceeded the limit by Malaysia Food Regulation 1985 (2011). As a conclusion, mud clams are a good bioindicator for heavy metal determination in their surroundings. Frequent water quality monitoring and heavy metals analysis in mud clams should be conducted to ensure food safety and human health in future.

  • Study on Water Pollution Impacts on Human Health from Water Usage based on
           Household’s Perception at Setiu River Basin

    • Authors: Puteri Syarifah Fakhira Mohd Yusri , Nadzifah Yaakub
      Pages: 98 - 108
      Abstract: Anthropogenic activity near the Setiu River basin can have a detrimental effect on people who use water in the area in terms of their body health. This study was important to assess the impact of river water degradation based on household perception so that the related parties can take intensive action to address this problem on the impact of river water degradation on human health. It involved 203 locals living along the Setiu River basin. Questionnaires were distributed and collected through face-to-face and "Google forms". The survey was conducted for four months from 1 January 2022 to 1 May 2022. All the respondents were locals who are Malaysian citizens. The data were obtained through questionnaires including questions based on a 5-point Likert scale and analysed by the Statistical Package for Social Science (SPSS) Software. Current water quality data was obtained through secondary data from the Department of Environment (DOE), Terengganu. The respondents' Income, Awareness, Knowledge, and Attitudes supported the hypothesis that demographic and socio-economic factors had significant differences in the risk perception for the impact of water pollution on human health. This study identified health issues related to the water pollution of Sungai Setiu among the residents from the questionnaire distributed by a regression analysis model.

  • Proximate Composition of Larvae, Prepupae and Adult in Black Soldier Fly
           (Hermetia illucens)

    • Authors: Nur Aizah Mohd Yusoff , Chung Thian Hai, Connie Fay Komilus
      Pages: 109 - 117
      Abstract: The black soldier fly (Hermetia illucens L.) is an insect species and able to convert low-value substrates is highly nutrient feed. Most of the aquaculture industry uses fish meal as a protein source in the diet of fish however fish meal was high in demand, price, and limited hence as an alternative the supplement protein should possess certain content to meet the role of fish meal in aquafeed products. Besides, a lack of research and studies on using BSF as a substitute in fish feed was noticed. This project aims to analyze the proximate composition in larvae, prepupae and adults were freeze-dried at -20°C, ground, and analyzed for proximate composition such as crude protein, crude lipid, ash, crude fiber, and moisture. Data were analyzed using one-way ANOVA to identify the significant difference in proximate composition in the three stages of BSF which are larvae, prepupae, and adult. As a result, the proximate composition revealed that BSF larvae possessed 32.3% crude protein, 26.7% crude lipid, 9.0% ash, 10.1% crude fiber, and 6.9% moisture while BSF prepupae contain 27.0% crude protein, 4.2% crude lipid, 10.6% ash, 8.6% crude fiber and 37.4% moisture also BSF adult have 52.6% crude protein, 15.6% crude lipid, 7.5% ash, 13.2% crude fiber and 25.6% moisture. BSF adult shows the highest crude protein content thus data was able to contribute more information on the nutritional value that potentially can be replaced in the diet of fish feed.

      Abstract: Fish meal (FM) is a well known protein source for fish feed and its heavy utilization has contributed to overfishing that lead to increase price of formulated feed due to scarcity of fish resources for fish meal. Several studies were done to identify the best substitution of FM including Black Soldier Fly (Hermetia illucens) larvae as a potential candidate for FM replacement. This study was done to investigate the proximate composition of Black Soldier Fly Larvae Meal (BSFLM) and to determine its efficacy as feed on growth performance of Javan Mahseer (Tor tambra). Three types of treatment were used namely F0 or control (0% BSFLM and 100% FM), F50 (50% BSFLM and 50% FM) and F100 (100% BSFLM and 0% FM). Each treatment was fed twice daily for 20 days to 10 Javan Mahseer with the average initial weight of 0.1g respectively. Analyses conducted was proximate composition and growth performance like specific growth rate, feed conversion ratio, survival rate and body weight gain. Data was analysed using One-way Analysis of Variance (ANOVA) SPSS Windows 27. Results show that crude protein in F0, F50 and F100 were 37.52%, 30.36% and 27.52%; while F50 indicated best BWG (66.71%) and lowest FCR (3.16) respectively. It can be concluded that treatment 50% inclusion of BSF is the best ratio for good growth performances of Javan Mahseer.

      Abstract: Heavy metals have become one of the environmental pollutants in water. To overcome this problem, the phytoremediation process was used as the method to cleanse polluted media. The objectives of the study are to determine the heavy metal accumulation by water spinach (Ipomea aquatica) in different types of heavy metal and to determine the level of heavy metal reduction in contaminated water. Ipomea aquatica was placed in containers that had solutions of different heavy metal concentrations. The selected heavy metals are cadmium (Cd), zinc (Zn), and copper (Cu), with a concentration of 5 ppm, 10 ppm, and 15 ppm, respectively. This study lasted about 20 days. Every four days, plant and water samples are collected. The plant samples were dried, digested, and analyzed by using ICP-OES. The two-way ANOVA statistical test was used to measure the differences in the amounts of the heavy metals accumulated in the plant and water. The accumulation of elements in plants shows a gradual increase in the uptake of cadmium, Cu, and Zn. Ipomea aquatica is suitable to take up cadmium, where the highest level of cadmium found was 13.99 mg/kg. On day 8, the level of heavy metals in the water gradually decreases for Cu and Zn. The presence of heavy metals in the water had decreased by 82.20 % on the last day of treatment. Ipomea aquatica accumulated more heavy metals while the number of heavy metals in the water decreased over a period of days. For all heavy metal types, significant differences in heavy metal concentration were obtained at p<0.05, showing that Ipomea aquatica can be used in the phytoremediation approach to remove heavy metals from wastewater.
