      Abstract: Horticultural plants are branches of agriculture that are associated with crop cultivation such as vegetables, fruit, various ornamental plants, and medicinal plants that require compounds to accelerate the formation of roots which can be done by using growth regulators. One of the growth regulators needed for plants is auxin or Indole Acetic Acid (IAA). The presence of bacteria that act as producers of IAA can be used to stimulate the growth of horticultural plants. Therefore, the exploration of bacteria that have the potential to produce auxin in the future can provide an important and significant role in increasing agricultural production. This study aims to isolate, select, measure the value of IAA, and characterize IAA-producing bacteria. Isolation of auxin-producing bacteria using general media of growth bacteria, i.e., Nutrient Agar (NA) and Nutrient Broth (NB). The location for sampling of rhizosphere soil was Prafi SP 1 Plantation, Manokwari, Indonesia. The results showed that as many as 9 bacterial isolates were obtained from the rhizosphere of horticultural plants. After selection of auxin-producing bacteria, 2 bacteria isolates (IBPA 3 and IBPA 5) were obtained which were able to produce IAA. IAA concentration value in IBPA 3 isolate is 42.178 ppm and in IBPA 5 isolate is 27.65 ppm. The characteristics of IBPA 3 isolate refer to the genus Bacillus and IBPA 5 isolate refer to the genus Pseudomonas.   Keywords: agriculture, bacteria rhizosphere, indole acetic acid

      Abstract: Viability and vigor are components of seed quality assessment which are influenced by internal and external factors of the seed, i.e., salinity and temperature. Salinity is related to the interaction between osmotic pressure and seed germination. This study used 3 types of seeds, they are peanuts (Arachis hypogaea L.), mung bean (Vigna radiata (L.) R. Wilczek), and corn (Zea mays L.). The purposes of this study were to determine seed viability by using Triphenyl tetrazolium chloride (TTC), to analyze the effects of different osmotic pressures and temperatures on seed viability and vigor. Peanut seed viability test was conducted by using 1% TTC solution. Testing the effect of osmotic pressure on seed viability and vigor was conducted by using various concentrations of NaCl (0.01 M; 0.05 M; 0.5 M; 0.1 M; 1 M). The germination test of the three seeds was conducted by using temperatures of 30°C and 35°C, each with three replications. The test parameters measured included germination, germination rate, germination speed index, vigor index, simultaneous growth, and the speed of seed growth. The results showed that TTC solution was effectively used to determine seed viability. Mung bean had the highest germination rate, LP, IKP, IV, simultaneous growth, and speed of seed growth compared to the other tested seeds in all salinity and temperature treatments. The 30 ⁰C temperature treatment resulted in the best viability and seed vigor for the three tested plants. Treatments of temperature and salinity affect the quality of the three plant seeds which can then be used to determine the quality of peanut, mung bean, and corn seeds.   Keywords: germination, salinity, triphenyl tetrazolium chloride, viability, vigour

      Abstract: The number and type of microorganisms in the soil indicate soil fertility. The use of fertilizers can affect the growth of microorganisms in the soil. Quantitative tests are conducted to evaluate how fertilizers affect the presence of bacteria, fungi, and algae. The number of bacteria and fungi is calculated using the standard plate count method, while the number of algae is calculated using the most probable number method. The highest number of bacteria found in urea-phosphate-potassium (UPK) applications of zeolite polymers is 50%, which is 3.4 × 106 CFU/mL; the most fungi are found in 25% of applications, which is 2.5 × 104 CFU/mL. In contrast, the highest algae population was in control soils, 2.7 × 104 CFU/mL. However, for treatment, an enormous amount is found in the administration of 50% zeolite polymer UPK as much as 1.4 × 103 CFU/mL, so it can be concluded that the administration of UPK zeolite polymer affects the number of microorganisms on the cornfield.   Keywords: soil microorganism, polyacrylate, UPK, zeolite

      Abstract: Organic fertilizers contain complete nutrients needed by plants, such as humic acid and fulvic acid, that can promote plant growth and increase the population of beneficial microbes in the soil. Algae can be an organic fertilizer in extract preparations that can increase plant growth and improve soil composition. The calculated number of microbes from the soil on corn land with the application of algae extracts affects the population of soil microbes both by standard plate count (SPC) and most probable number (MPN) methods. The total number of bacteria by SPC in the control soil was 3.1 × 105 CFU/g, while the total fungus was only 1.7 × 104 CFU/g upon applying 5% algae extract. The most microalgae by MPN in the control ground was estimated to be 2.6 × 104 cells/g. Therefore, the application of algae extract affects the number of soil microbes on corn land compared to control soil. The algae extract reduces the number of bacteria and algae but increases the number of fungi on cornfields.   Keywords: algae extracts, cornfields, soil microbes

  • Distribusi dan Luas Stomata pada Enam Jenis Tanaman Dikotil

    • Authors: Rini Primawati, Entin Daningsih
      Pages: 27 - 33
      Abstract: Stomatal distribution and area are related to transpiration rate. This study measured stomatal distribution and area in dicotyledon plants used as ornamental plants. The study used Factorial Completely Randomized Design (CRD) with the main factors were six types of dicotyledon plants and three plant parts (top, middle and bottom). Combination factors were the interaction of plant species and parts. By using the replica method and micrometer, the study used five replications with the measured parameters: the stomatal distribution and area. Data were analyzed using SAS with the Factorial RAL model and continued with the LSD test if the treatments were significant. Correlation coefficients between stomatal distribution and area were calculated to see the relationship between the two. The types and plant parts significantly affected the stomatal distribution, while the stomatal area was influenced by the main and combination factors. Syzygium paniculatum Gaertn had the highest stomatal distribution and was different from other plant types. Meanwhile, lower leaves had the lowest stomatal distribution and differed from the middle and upper. Aerva sanguinolenta Bl had the highest stomatal area (591.05) compared to other plant species. The stomatal area on the plant's upper leaves (272,71) was significantly lower than the middle and lower parts. The combination between species and the lower part of the plant produced the highest stomatal area compared to other combinations. Stomatal distribution was inversely proportional to the stomatal area.    Keywords: dicotyledon, part of plant, stomatal area, stomatal distribution

      Pages: 34 - 39
      Abstract: Ornamental plants give beauty to the surrounding environment. Fresh air is created around the plant. It is concerned with transpiration which relates to the distribution and extent of stomata. The study measured the distribution and extent of stomata in monocot plants used as houseplants. The experimental design used a complete randomized design (RAL) factorial with five replications. The main factors were six types of monocot plants and three parts of plants (top, middle, and bottom). The interaction between plant types and parts was a combination factor. The distribution and area of the stomata were measured using replica methods and micrometers. The data was analyzed using the factorial RAL model statistical analysis system and followed up with the smallest real different test for significant treatment. The distribution of stomata was correlated with the stomata area to observe the relationship between the two. Plant types, plant parts, and combinations of both have a noticeable effect on the stomata distribution and area. The Paris lilies (Chlorophytum comosum (Thumb) Jacq.) have the highest stomata distribution (20.53%) compared to others, with a stomata area of 291.89 μm2. Meanwhile, the top part of the plant has the highest distribution and differs from the middle and bottom. The highest stomata distribution is at the top of the plant (15.02%) and lowest at the bottom (11.96%), while the smallest stomata area is at the top of the plant (687.62 μm2) and the widest is at the bottom (813.88 μm2). The stomata distribution correlates inversely with the stomata area of both plant types, plant parts, and a combination of both.   Keywords: ornamental plants, monocotyledon, stomatal area, stomatal distribution

  • Ketebalan Daun dan Laju Transpirasi Pada Tanaman Hias Dikotil

    • Authors: Yuliana Ovan Dacosta, Entin Daningsih
      Pages: 40 - 47
      Abstract: Transpiration rate internally depends on the water content that occupies the tissue in the leaves, which is reflected in the thickness of the leaves. This study measured the transpiration rate and leaf thickness of ornamental dicotyledon plants. The experiment used Factorial Completely Randomized Design (CRD) with three replications. Six species of dicotyledon plants and three parts of the plant were the main factors. The interaction between plant species and plant parts was a combination factor. The transpiration rate was measured using a weighing method and leaf thickness was measured from the upper to the lower epidermis. Leaf thickness was measured before and after transpiration rate measurement. Data were analyzed using SAS with Factorial CRD model and continued with the LSD test if there was a significant treatment. The species of plant and plant parts had significant effects on the transpiration rate and leaf thickness, but the combination or interaction of the two did not affect the transpiration rate and leaf thickness. Aerva sanguinolenta Bi. had the highest transpiration rate followed by Syzygium paniculatum Gaertn., Tabernaemontana divaricata (L.) R. Br. ex Roem. & Schult., Excoecaria cochinchinensis Lour., Bougainvillea glabra Choisy, and Codiaeum variegatum (L.) A. Juss while the leaves at the bottom of the plant had the highest transpiration rate compared to the middle and upper parts of the plant. Codiaeum variegatum (L.) A. Juss. had thick leaves and less transpiration rate than the other plants. The leaves at the top had a higher thickness than those at the middle and bottom parts of the plant. This occurs because the transpiration rate of the lower leaf was faster than the upper and middle parts. Leaf thickness was inversely correlated to the rate of transpiration.   Keywords: dicotyledon, leaf thickness, transpiration rate

      Abstract: This study aimed to determine the effect of refugia (Tagetes erecta and Zinnia elegans) plants on the relative abundance and diversity of Arthropod's dominance in the rice plant area and on rice yield. The Arthropods were observed by the visual control method at each rice growth stage. Observations were made during 15 minutes in five plots of rice area and one refugium block at three different times (08.00‒10.00, 12.00‒14.00, and 15.00‒17.00. The morphological features were identified and recorded to identify the species level and grouped according to their ecological niches. The relative abundance and Shannon Diversity Index were calculated. The rice plants' growth data and yield components were analyzed by ANOVA followed by DMRT if there were any significant differences among the treatments. Relative abundance of dominant arthropods on rice land planted with Zinnia elegans was Solenopsis geminata (11.07%), Leptocorisa oratorius (38.37%), and Hypolimnas bolina (0.17%) with species diversity index values of 3.25%; 2.94%, and 2.56%, respectively. In contrast, the relative abundance of arthropods in rice land planted with Tagetes erecta were Cardiochiles philippinensis (8.84%), Oxya chinensis (25.45%), and Scirpophaga incertulas (0.34%) with moderate diversity index values. The Tagetes erecta gave an equivalent result of rice yield with the control, namely 8,10 t/ha and 7,60 t/ha, respectively, while the Zinnia elegans offers rice yield of 6,30 t/ha.   Keywords: arthropod diversity, paddy yield, Tagetes erecta L, Zinnia elegans

  • Studi In Silico Senyawa Cendawan Endofit Sebagai Kandidat Obat
           Antiangiogenesis Hemangioma

    • Authors: Masriany Masriany, Risman Rifaldi, Eka Sukmawaty
      Pages: 62 - 69
      Abstract: Increasing levels of angiogenic factors such as gamma interferon (Y-IF), tumor necrosis factor-beta (TNF-β), and transforming growth factor-beta (TGF-β) are thought to be the cause of the angiogenesis process in hemangiomas. Endophytic fungi are potential in searching for new drug sources due to their antimicrobial, antifungal, and anticancer compounds. This study aimed to determine the potential and interactions of endophytic fungi as candidates for vascular endothelial growth factor receptor-2 (VEGFR-2) angiogenesis hemangiomas and apply Lipinski's rule of five to differentiate drug-like and non-drug-like molecules and in-line toxicity using in silico test. The research method was molecular docking using several programs, namely Autodock Vina (PyRx), PyMol, and Discovery Studio 2019, and tethering five ligands from the endophytic fungus Trichoderma sp. and Aspergillus sp. with 2 VEGFR-2 target proteins (protein codes were 3VHE and 1Y6A). The best binding affinity of the ligands was tested by Lipinski's rule of five and toxicity test using Toxtree. The results showed that benzyl benzoate is potentially an antiangiogenesis inhibitor for VEGFR-2 protein based on its binding affinity value, which is close to the control ligand value of -8.7 kcal/mol (3VHE) and -7.4 kcal/mol (1Y6A). Therefore, benzyl benzoate, chloromycetin, and 1-hexyl-3-nitrobenzene compounds comply with Lipinski's rule of five. Based on the results of the toxicity test and the parameters of the Kroes TTC decision tree, benzyl benzoate and chloromycetin are categorized as safe compounds for consumption.   Keywords: angiogenesis, benzyl benzoate, endophytic fungi, molecular docking, VEGFR-2

      Abstract: Marine bacteria associated with sponges can be used as a source of new enzymes, especially cellulase which are potentially used for various industries. The aim of this study was to screen and identify the cellulolytic bacteria associated with sponges. A total of 38 isolates have been successfully isolated from sponges Aaptos sp., Euryspongia sp., and Haliclona sp. by a spread plate method. Amongst 38 isolates, 14 (37%) showed cellulolytic activities in carboxy methyl cellulose (CMC) medium with a cellulolytic index ranging from 0.31 to 1.63. The three highest cellulolytic index was exhibited by bacterial isolates coded Y.5.10, Y.5.11, and Y.40.6. Isolates Y.5.10, Y.5.11, and Y.40.6 showed cellulolytic activity of 0.0053 U/mL; 0.0083 U/mL; and 0.0124 U/mL, respectively, as were tested by spectrophotometry. The highest specific enzymatic activity was showed by isolate Y.40.6 with a value of 0.3391 U/mg. Based on 16S rRNA gene, isolate Y.5.10, Y.5.11, and Y.40.6 were highly similar to (similarity ≥ 99%) Bacillus sp., B. subtilis, and B. cereus, respectively.   Keywords: cellulase, isolation, sponge-associated bacteria, 16S rRNA

      Abstract: The study aims to isolate and test the effectiveness of mutualistic root symbiont fungi isolates from the roots of rubber plants grown in marginal acidic soil plantations in increasing the growth of food crops and forestry plants. The fungal were isolated by root surface sterilization methods. We obtained 19 fungal isolates consisting of 8 genera, namely Alternaria, Aspergillus, Cladosporium, Curvularia, Fusarium, Penicillium Paecilomyces, Trichoderma, and mycelia sterilia. All isolates were subjected to a pathogenicity test on the Centrosema pubescens plant. Five out of the 19 fungal isolates increased plant growth and showed no disease symptoms, and the Aspergillus section Nigri FKK 3 isolate showed the best response. The isolate was further analyzed to assess the growth response of food crops (rice and corn) and forestry plants (Acacia auriculiformis and Paraserianthes falcataria). The treatments consisted of 3 phosphate (P) concentrations, namely 20%, 50%, and 100% of the recommended field applications. The combination of mutualistic fungal inoculation of Aspergillus section Nigri FKK 3 and 50% P concentration exhibited the highest biomass growth response compared to other treatments. This finding can provide basic information for developing fungal-based fertilizers to increase the productivity of food crops and forestry plants on sub-optimal land.   Keywords: food crops, phosphate fertilizer, forestry trees, plant growth improvement, root mutualistic fungi

      Abstract: Environmental conditions and fish stocking density in tilapia cultivation (Oreochromis niloticus) are important factors in determining the success of the cultivation process and supporting optimal fish growth. This study used four treatments, namely A, B, C, and D, for 3, 5, 7, and 9 fish, respectively. The purpose of this study was to determine the effect of raccoon tail plants (Ceratophyllum demersum) and genjer plants (Limnocharis flava) on tilapia mortality, determine the ratio of feed conversion and the effect on ammonia concentrations, determine the effect of ammonia concentrations on the productivity of genjer plants, determine the warning system modeling on ammonia concentrations, as well as calculate mass and energy balance in the cultivation system of tilapia and genjer. The result is that the planting of raccoon tails and genjer in the system significantly affects tilapia mortality. The average value of feed conversion ratio from treatments A, B, C, and D were 1.75; 1.36; 3.51; and 2.87, respectively. The effect is significant and directly proportional to ammonia concentration and genjer productivity. The ammonia warning system modeling is in the form of linear equations, namely y = 0.2085x - 0.0193 with R2 = 0.9692. This system's balance of mass and energy can be divided into three subsystems, namely, fish acclimatization, fish cultivation, and genjer cultivation.   Keywords: ammonia, genjer, modelling, tilapia

      Abstract: Arbuscular mycorrhiza (AM) characteristics of citronella grass in the field have not been reported. This research aimed to study the AM characteristics of citronella grass grown in unshaded and shaded fields. The roots of citronella grass were collected from citronella grass plantations in Cianjur, West Java. The root samples were analyzed for AM structures, namely entry points, intercellular hyphae, arbuscules, and vesicles. The results showed that the citronella grass form AM colonization. The quality of root colonization differed between the two cultivation systems. The unshaded citronella grass had higher root colonization compared to shaded citronella grass. In the unshaded citronella grass, the number of arbuscules was 7 per cm of root length, whereas in the shaded citronella grass was 4 per cm of root length. The types of arbuscules observed were arum and intermediate. There were no differences in the number of entry points in the two cultivated systems, which was 3,5 entry points per cm of root length. The numbers of vesicles and internal hyphae in unshaded citronella grass were lower than that of in the shaded citronella grass. In the unshaded citronella grass, the number of vesicles and intracellular hyphae were 1,5 and 8,5 per cm root length, whereas in the shaded citronella grass were 3,5 and 11 per cm root length, respectively. Shading plants grown in the field were bamboo, banana, coffee, tea, and sugar palm. All the shading plants formed AM symbiosis with a colonization value of 7 to 30%. This research indicates that arbuscular mycorrhiza is an important component in the citronella grass cultivation in unshaded and shaded fields.   Keywords: Arbuscule, entry point, intercellular hyphae, root colonization, vesicle

      Abstract: The purpose of this research was to assess effect of compost treatment from various local organic materials combined with agro-industrial waste to improved chemical quality of acid sulfate mineral soils, to compare of root dry weight and grain weight milled dryness of Inpara-3. This research was conducted at screen house of Polytechnic Hasnur, Barito Kuala District, South Kalimantan from November 2020 to June 2021. This study used Compeletely Randomized Design (CRD) with Tukey's Honestly Significant Difference (HSD) test a=5%. There were 7 treatments used as, K0 = control. JKD = paddy straw compost 4 t ha-1 and solid decanter 2 t ha-1; JKR = paddy straw compost 4 t ha-1 and solid crumb rubber 2 t ha-1; SKD = empty fruit bunch compost 4 t ha-1 and solid decanter 2 t ha-1; SKR = empty fruit bunch compost 4 t ha-1 and solid crumb rubber 2 t ha-1; PKD = compost of purun tikus (Eleocharis dulcis) 4 t ha-1 and solid decanter 2 t ha-1; PKR = compost of purun tikus 4 t ha-1 and LPKR 2 t ha-1. The treatment was 5 replication so that 35 experimental plant units. The results showed compost paddy straw combinated solid decanter reducing concentration of soluble Fe and Al and can increasing availability of P and K. Treatment of compost empty fruit bunch combinated solid decanter can be increasing pH and total N-mineral. Compost paddy straw combinated solid crumb rubber gave increasing weight on root dry and grain milled dryness.   Keywords: acid sulfate soil; agroindustrial wasted; compost

      Abstract: The circumstance of suboptimal land, due to its complex and often difficult nature, is either under-utilized and becomes abandoned space or over-utilized and generates environmental problems. In fact, suboptimal land, including peatlands, can be an alternative amid the decreasing area of arable land per capita for agriculture. This study aims to assess the contribution of sustainable agriculture for coconut commodities in the peatlands area, Pulau Burung District, Indragiri Hilir Regency, Riau Province. Data on environmental aspects were obtained from secondary data provided by the local company. Data on socio-economic aspects were obtained using focus group discussions (FGD) in five villages through semi-structured interview to 29 residents from various backgrounds. As a result, agricultural practices in this area can be deemed as sustainable based on water management indicators. The environmental impact is very minimal, biodiversity is preserved, and the subsidence rate is very low at 1.7 cm per year. In terms of socio-economic aspect, it can be concluded that the community perceives the environmental and social aspects are well maintained. Referring to the results of the FGD on agricultural practices, land fire control, food access, waste management, and water access are aspects that are considered adequate for the community. In contrast, land governance scored the lowest due to the difficulties in obtaining land certificates.   Keywords: peatland, suboptimal land, sustainable agriculture, water management

      Abstract: A greenhouse is an agricultural management system that has shown the efficiency of food production. This system is an effective alternative to ensure maximum production results. Agriculture with greenhouse technology can create the desired environmental/climatic conditions. The rapid development of technology and science has led to the birth of communication between devices using IoT and AI. This technology can be applied to greenhouses in agriculture and fisheries. Research on greenhouse and microcontroller-based automation systems has been carried out, and it is interesting to be developed. Researchers make a more efficient system and can increase the quality and quantity of production. The measurement data of both modes are monitored using the web. The greenhouse prototype is supported by DHT22, DS18B20, a fan to control the greenhouse cooler, RFID as the key access to the greenhouse. DHT22 & DS18B20 sensor readings in the prototype greenhouse use an AI system with the fuzzy method. IoT and AI have been successfully implemented in models of rice fields, hydroponic farming, and fisheries using automatic modes of RTC devices and sensors. The fuzzy approach method is used to find the optimum temperature and humidity values. The fuzzy approach was successfully carried out until the temperature and humidity conditions were "ideal," "high," and "very high." This condition provides information to the microcontroller to activate which fan should turn on. In manual mode, the smartphone application controls the system properly.   Keywords: artificial intelegent, control and automation, fuzzy logic, greenhouse, IoT
