  • Values of Cassava Tuber Peels Produced in the Farms and Home-Scale Snack
           Food Industries as Feed Based on Yield Rate, Crude Nutrient, and Mineral

    • Authors: Khalil Khalil
      Pages: 75 - 81
      Abstract: The Payakumbuh region is an important tourist destination in West Sumatra. They produce various snack food made from cassava tubers, producing a large cassava peel as a by-product. The research aimed to study the meal yield rate, crude nutrient, fiber fraction, and mineral composition of cassava peels as by-products of cassava farm and snack food industries. Twenty cassava farms and ten snack food industries were visited, and the owners were interviewed for data on the type of cassava used, products, and handling of cassava peel. The quantity of cassava peel produced and potentially used as feed was recorded. Samples of fresh peels from three different varieties and tuber sizes were collected, weighed, dried, and ground in meal form to determine the meal yield rates and analyze for dry matter (DM) content, crude nutrient, fiber fraction, and mineral composition. Results found three cassava cultivars used to produce snack foods, i.e., black, bread, and sticky cassava. The percentage of fresh peel and meal yield rates ranged from 16.4-16.7% and 21.9-26.9%, respectively. DM and crude protein content varied between 23.8 to 27.0% and 9.3 to 11.2%, respectively. Bread cassava peels showed the highest DM, ash, and ADF content. Cassava peel contained considerably high Fe and was a good source of K, Mg, P, Na, Mn, and Zn.

  • Estimation of Repeatability and the Most Probable Producing Ability (MPPA)
           Based on Birth Weight and Weaning Weight for Ranking of Sapudi Sheep

    • Authors: A. A. Mirella, Mudawamah Mudawamah, Sumartono Sumartono
      Pages: 82 - 86
      Abstract: This study was conducted to estimate the repeatability and MPPA values of Sapudi ewe based on birth weight and weaning weight. Samples used 93 Sapudi lambs from 26 ewes that lambed three times, and the observed variables were lambing weight and weaning weight. Collected data were analyzed quantitatively. Estimating repeatability by analyzing the variance of the relationship between sibling and the parental rank was based on the relative MPPA formula.. The results showed that the average lambing and weaning weights were 2.789±0.206 kg and 10.058±1.470 kg. The repeatability of lambing and weaning weight were 0.108±0.119, and 0.565±0.104 belonged to the low and high categories. The average MPPA of lambing and weaning weight were 0.001 and 0.087. MPPA values of lambing and weaning weight range from -0.087 to 0.075 and -1.721 to 2.713. The highest ranking of the Sapudi ewe in lambing and weaning weight is ear tag 103 and ear tag 27 with MPPA 0.075 and 2.713. It can be concluded that there were 11 ewes with MPPA lambing and weaning weight above the average MPPA population that should be maintained in the population.

      Pages: 87 - 90
      Abstract: This research aimed to examine the effect of Terminalia catappa extract in drinking water on Crossbred-native chicken's performance and carcass production. The research was arranged in a completely randomized design with five treatments and 5 replications (8 birds each). The samples in the present study were two hundred crossbred native chickens with an average body weight of 120.58±12.60 g. The treatments were as follows: drinking water without Terminalia catappa extract (T0); Drinking water with 1% of fresh Terminalia catappa leaf extract ten ml/1 l water (T1); Drinking water with 2% of fresh Terminalia catappa leaf extract 20 ml/1 l water (T2); Drinking water with 3% of fresh Terminalia catappa leaf extract 30 ml/1 l water (T3); Drinking water with 4% of fresh Terminalia catappa leaf extract 40 ml/1 l water (T4). Parameters observed were drinking water consumption, feed consumption, body weight gain, feed conversion ratio, and carcass production. Results show that Terminalia catappa extract in drinking water significantly affects drinking water consumption but has no effect on other parameters. Fresh Terminalia catappa leaf extract can be used in drinking water until 4%.

      Pages: 91 - 96
      Abstract: This study aimed to evaluate the effect of fermented gamal leaf flour as a substitute for concentrate in the basal ration on the performance of landrace crossbreed pigs. The materials used in this study were 16 landrace crossbred male pigs at the starter phase aged 1–2 months, with an average of 7.56 kg and KV of 40.68%. The design was a randomized block design with four treatments and four replications. The treatments were R0: basal ration + 100 concentrate without fermented gamal leaf meal (FGLF), R1: basal ration + 90% concentrate + FGLF 10%, R2: basal ration + 80% concentrate + FGLF 20%, R3: basal ration + 70% concentrate + 30% FGLF. The results of variance showed that the use of fermented gamal leaf flour (FGLF) as a substitute for concentrate in the basal ration of landrace crossbreed pigs had no significant effect (P>0.05) on performance. This study concluded that using fermented gamal leaf flour as a substitute for concentrate in basal rations in landrace crossbreed pigs gave relatively the same results up to 30%.

    • Authors: U. Adiati, S. Rusdiana
      Pages: 97 - 104
      Abstract: This study aimed to determine the management of the genetic resources of St. Croix sheep and Garut sheep in the formation of sheep clumps and their physiological conditions. The study was conducted at the Livestock Research Institute on Jalan Raya Pajajaran Bogor, West Java, in 2019. Ex-situ collection materials and characterization of St. Croix sheep and Garut sheep were as many as 250 heads; sheep breeding was carried out in groups; one male married 5-10 heads. The rams were left in the mating group for two oestrus cycles (34 days). Primary data and secondary data were analyzed descriptively and quantitatively. The results were obtained in the germplasm research of St. Croix with an average mating body weight of 23.45 ± 4.08 kg and Garut sheep of 26.20 ± 4.92 kg. The average birth weight of St. Croix sheep was 2.26+0.35 kg, and Garut sheep was 2.05± 0.47kg. The establishment of the St. Croix and Garut sheep have high genetic quality, production, and reproductive characteristics, but each has a different productivity level. The study of germplasm preservation of sheep was carried out to increase the population of St. Croix sheep and pure Garut sheep so that the maximum target population of >200 sheep was achieved to meet the demand for seeds as animal food.

      Abstract: The development of pig farming aims to support the economy of the people in the Southwest Sumba Regency. Pigs in this area have a very high cultural value, so they have promising potential and prospects in the future. The problem is that the maintenance system is still semi-extensive and tends to be traditional. This situation can be related to the motive in trying and efforts to adopt an innovation. This study aimed to analyze the level of motivation and the factors that influence the adoption of innovation in raising pigs. The research method used a survey method with direct observation in the field. They are determining the area using the multistage cluster random sampling method obtained from sample sub-districts, namely Tambolaka District (Tambolaka City and Wee Londa) and South Wewewa District (Tena Teke Village and Delo). The research material was 120 pig farmers taken by purposive random sampling. The measured variables include the motivation to raise livestock using a Likert scale and factors influencing innovation adoption using multiple linear regression tests. The software used is Eviews 10. The study results show that: 1) Most of the pig breeders in Southwest Sumba Regency are based on high economic, social, and entertainment motives in pig farming. 2) The regression results show that the variables that have a significant effect on the level of adoption with a prob value below the significant level of 0.05 are the variables of motivation and access to information. While the variables that have no significant effect on the level of innovation adoption with a prob value above the significant level of 0.05 are the variables of age, education level, family dependents, livestock experience, number of livestock, and accessibility. This study concludes that business motives and adoption of innovations affect the success or failure of pig-rearing businesses in the Southwest Sumba district.

  • Quality of Chemically Processed Flying Fish (Hyrundicthys oxycephalus)
           Waste Silage

    • Authors: L. Ambarwati, I. Andriani, T. Taufik, M. Marsudi
      Pages: 119 - 125
      Abstract: Flying fish are the fish that are widely found in the waters of the Makassar Strait, especially in Majene Regency. During the harvest season, flying fish leave a lot of waste that pollutes the environment. This research aimed to evaluate flying fish waste silage's physical and chemical qualities. The design used was a completely randomized design (CRD) with four treatments and four replications groups. To process the sample, formic acid at concentrations of 0%, 2.5%, 3%, and 3.5% was used. Anova was applied for data analysis, followed by Duncan's test if the treatments differed significantly. Parameters observed were chemical quality, including crude protein and fat content, total bacteria count, and pH, while physical-chemical quality included aroma, color, and texture of flying fish waste silage. The results showed that the addition of formic acid to fly fish silage had a significant effect (P < 0.05) on protein, fat, pH, and total bacteria levels but had no significant effect (P> 0.05) on the aroma, color, and texture of the hay. This research concludes that chemically processing flying fish silage with the addition of 2.5% formic acid can increase the protein content to the optimum level in the P1 treatment resulting in the highest protein content of 48.81% and the fat content of 1.63%, pH 3.5, total bacteria 4 x 104, sour taste, gray color and liquid texture that can be safely used as raw feed.

  • Macroclimate at Different Altitudes on Changes in Microclimates in a
           Closed House

    • Authors: H. Wahyuningrum, L. D. Mahfudz, R. Muryani
      Pages: 126 - 133
      Abstract: This study was conducted to determine and analyze the effect of differences in altitude levels on the macroclimate and microclimate in a closed house. This research was carried out at a closed house in the lowland, medium land, and highland with a length of 120 m and a width of 12 m. Observed data were made for 28 days at three times. Parameters observed include temperature, wind speed, humidity, and solar radiation. Macroclimate contribution to the microclimate was calculated based on the relationship's strength using correlation analysis and forming a regression equation. The results showed that the gift of macroclimate components to microclimate conditions in the form of temperature and humidity was more significant in the cages in the lowland and highland. In contrast, the contribution to wind speed was minimal. The predictor of air humidity in a cage in the lowland during the brooding phase was influenced by temperature, humidity, wind speed, and solar radiation; during the finisher phase, the temperature and humidity in the cage in the lowland were influenced by temperature, humidity, and solar radiation. This study concluded that the contribution of macroclimate factors to microclimate conditions in the brooding phase is more significant in the cage in the lowland. In comparison, in the finisher phase, the contribution is more important in the lowland and medium land.
