Abstract

This research aims to examine the fermentation process in mushroom baglog waste and bat guano as ingredients for making multinutrient fertilizer, as well as to determine the fermentation time and composition ratio of the best raw materials with the highest and appropriate nutrient content according to the 2019 Ministry of Agriculture Regulation. The research was carried out in June - August 2023 located at the Graha Riset Universitas Pembangunan Nasional ‘Veteran’, East Java. Making multinutrient fertilizer from white oyster mushroom baglog waste and bat droppings is carried out using an anaerobic fermentation process with specified variables, namely: total mass of material: 10kg, volume of EM-4: 10ml, mass of sugar: 10 grams, and volume of water: 500ml. The research was carried out with variable fermentation times (days): 8, 12, 16, and 20 and composition ratios (baglog waste: bat droppings): (3:1), (2:1), (1:1), (1: 2), and (1:3). The results of the research show that the fermentation process helps decompose organic material as indicated by changes in levels of nitrogen, phosphate, potassium, and C/N. The decomposition of organic material in the fermentation process is indicated by physical changes that occur such as reduced water content due to the increase in temperature of the fertilizer during the fermentation process, changes in pH, as well as the blackish brown color of the fertilizer and a texture that resembles the texture of soil. The best fermentation time and ratio of raw material composition with the highest nutrient content was obtained on the 16th day of fermentation with a ratio of 3:1 with a Nitrogen content of 4.22%, Phosphate 3.14%, Potassium 4.25%, and C-Organic 27. 22%. Overall, the levels of Nitrogen, Phosphate, Potassium and C/N in the multinutrient fertilizer produced with variable time and composition in this study have met the 2019 Minister of Agriculture Regulation.

Abstract

Currently, there were 24 provinces in Indonesia experiencing a deficit of shallots. In Bengkulu province, the deficit of shallots reached 83.37%. The productivity of shallots in this province was very low, which was less than 1 ton per hectare. This study aimed to evaluate the responses of growth and yield of shallots with the applications of fish waste-based organic fertilizer prepared with local and commercial bioactivators. The study was conducted with a Randomized Block Design in 2 factors and 3 replications. The first factor was the type of fish waste-based organic fertilizer prepared with different bioactivators, namely bamboo shoots and EM-4. The second factor was the dosages of fish waste-based organic fertilizer, namely 0, 10, 20, and 30 t/ha. The main findings from this study are as followed. Fish waste-based organic fertilizer prepared with bamboo shoot bioactivator had a better effect compared to EM-4 bioactivator in terms of plant height, number of shoots, number of bulbs, bulb diameter, fresh weight of bulbs and dry weight of bulbs. The dosage that gave the best effect was 30 tons/ha, where the increasing of the dosages was consistently increased all variables observed.

Abstract

The purpose of this study is to analyze the composition of weeds and the growth of lowland rice influenced by the use of TOT cultivation technology and varying weeding frequencies. The study was carried out between June and November 2024. The approach employed in this research was an experimental method utilizing a split plot design, with two primary factors: the application of cultivation technology (B), featuring two treatment conditions, and the frequency of weeding (F), with six different levels of treatment. A combination of treatment plots was established for each block. Weed samples were taken at 7 points in each combination plot diagonally, using a square freem of 50cm x 50cm. Weed identification results were analyzed for dominance values (S.D.R) and Diversity Index (H') based on Shannon-Wiener. Data on weed dry weight and paddy growth obtained were analyzed using ANOVA, with a further DRMT (Duncan) test at the 5% level.Result of the research show that TOT cultivation technology and weeding frequency have a significant effect on weeds and rice growth. The most weeds were found in the conventional system with 37 species with the dominant weed being Cynodon dactylon for those that were not weeded and Pistia stratiotes for those that were weeded. In the TOT system, 24 species were found with the dominant weed Pistia stratiotes in both weeded and unlit fields, with the diversity index in each treatment being moderate. A weeding frequency of 3 times provides the lowest dry weight of weeds. on the number of tillers at the age of 40 DAP and the frequency of competition had the best effect on weed suppression and the number of leaves per hil

Abstract

The productivity of mung beans in East Nusa Tenggara for the last five years has been recorded at around 0.89 tons/ha, which is lower than the potential yield of superior varieties. This research focuses on increasing the productivity of mung beans through fertilization and the use of renewable technologies, especially bodacious elicitors, and NPK fertilizers. The study aimed to examine the effect of bodacious elicitation and NPK fertilizers on yield components and nutrient uptake from local varieties of mung bean. Using a Random Design of a group of factorial patterns, the first factor has two levels: without biosaka (B0) and with biosaka (B1).The second factor is the dose of NPK Phonska Plus fertilizer, consisting of 4 levels, namely 100% NPK (P1 = 250 kg/ha), 80% NPK (P2 = 200 kg/ha), 60% NPK (P3 = 150 kg/ha) and 40% NPK Plus (100 kg/ha).  The data was analyzed using variance analysis and continued with Duncan's Multiple Range Test. The results showed that the treatment could increase the nitrogen (N), phosphorus (P), potassium (K), and cation exchange capacity (KTK) of soil, as well as nutrient uptake at lower NPK doses. In addition, it positively affected the number of pods, pod weight, 100 seeds, and mung bean seed yield. The combination of biosaka with a dose of 40% NPK resulted in higher mung bean seeds.. This study recommends using biosaka as one of the strategies to increase mung bean productivity with more efficient NPK fertilization to support agricultural sustainability in East Nusa Tenggara.

Abstract

Seed dormancy poses a serious challenge when aiming for precise and uniform sowing times in crop cultivation activities. Dormancy can reduce seed viability thus inhibiting germination and early plant growth. The purpose of this study was to test the effectiveness of gold snail extract enriched with PGPR (Plant Growth Promotion Rhizobacteria) bioactivator by optimizing the length of soaking in local rice seeds that experience dormancy. The research was conducted using a Completely Randomized Design (CRD) with 5 treatments of control soaking duration (P0), 12 hours soaking duration (P1), 24 hours (P2), 36 hours (P3) and 48 hours (P4) with 4 replications so that a total of 20 experimental units were obtained. Each experimental unit consisted of 25 local Kamba rice seeds by observing the percentage of germination, vigor index, growth speed, fresh weight, dry weight, root length and pH changes during the fermentation process. The results showed that various treatments of soaking time in gold snail extract enriched with PGPR bioactivator did not provide statistically significant differences in the germination of local rice seeds that experienced dormancy. However, there was an increasing trend in all observation parameters indicating that the viability and vigor of seeds soaked in gold snail extract for 36 hours (P3) were better than the control. pH and temperature observed before and after fermentation, showed conditions that remained optimal. The combination of gold snail extract added with PGPR as a bioactivator is an alternative solution that can accelerate the breaking of dormancy, increase seed viability and vigor as an effort to support more optimal and sustainable early growth of rice plants.

Abstract

South Tapanuli , North Tapanuli, Humbang Hasundutan and Dairi districts are in the Sumatera Utara Province. These four districts are producers of the Arabica debt variety of Arabica coffee and are the source of the varieties used as plant material for research.  The aim is to determine the dosage of magnesium fertilizer through the soil and leaves on the vegetative growth of Arabica coffee of the Sigarar Utang Variety which experiences symptoms of magnesium deficiency. This research was designed by factorial Completely Randomized Block Design consisting of 2 factors, namely the dose of magnesium fertilizer 4 levels, namely M0 (0 g / plant), M1 (10 g / plant), M2 (20 g / plant) and M3 (30 g / plant) applied through the soil and leaves and the source of the variety source 4 levels, namely B1 (South Tapanuli), B2 (North Tapanuli, B3 (Humbang Hasundutan), B4 (Dairi) with 3 replications. The variables observed were the increase in plant height (cm), Leaf Area (cm2) and Magnesium nutrient content in coffee leaf tissue (%). The results showed that the treatment of magnesium fertilizer doses through soil and leaves and the source of the Sigarar Utang Variety had a significant effect on the results. The level of magnesium fertilizer dose treatment of 30 g / plant applied through soil and leaves resulted in maximum increase in plant height (cm), leaf area (cm2) and magnesium nutrient content in coffee leaf tissue (%). The highest and best source of the Sigarar Utang Variety was produced by varieties from Dairi district and the response of the plant to the application of magnesium fertilizer was more maximal absorption of nutrients through soil and leaves, so that the magnesium nutrient content in the tissue leaves (%) and plant height increase (cm) are higher than the source level of other Sigarar Utang Varietties

Abstract

This study was conducted to determine the effect of Zinnia elegans plant spacing as a refugiaplant on the abundance of natural enemies and the level of pest attacks on soybean (Glycinemax). The study used a non-factorial Randomized Block Design (RBD) with five treatments:no refugia (J0), and plant spacing of 40 cm (J1), 60 cm (J2), 80 cm (J3), and 100 cm (J4),each with four replications. The parameters observed included the identification andpopulation of natural enemy insects, the abundance of natural enemy insects, the area andintensity of pest attacks. Data analysis was carried out using analysis of variance andcontinued with the LSD test at the 5% level. The results showed that the 40 cm plant spacing(J1) was the most effective treatment, resulting in the highest abundance of natural enemies(31 individuals from 4 families) and the lowest pest population (2 individuals). Treatment J1also showed the lowest pest attack area (5.47%) and very light attack intensity (3.62%),while the control (J0) showed an attack area of 23.47% and an attack intensity of 19.42%,which is classified as moderate. The high abundance of natural enemies at a plantingdistance of 40 cm indicates the effectiveness of refugia in creating microhabitats that supportnatural predators in the soybean planting ecosystem. These data indicate that the use ofZinnia elegans refugia at optimal planting distances can suppress pest attacks whileincreasing soybean plant productivity. Therefore, the integration of refugia plants withappropriate planting distances can be an effective, environmentally friendly biologicalcontrol strategy and support sustainable agriculture.

Abstract

Kidney beans (Phaseolus vulgaris), belonging to the Leguminosae family and classified as C3 plants, typically exhibit slower photosynthesis and lower biomass production under high light intensity and hot temperatures. To overcome these limitations and enhance photosynthetic efficiency, external stimulation of plant physiological processes is crucial. One promising approach involves the application of Photosynthetic Bacteria (PSB), known for their independent photosynthetic capabilities. This study aimed to evaluate the impact of PSB application at various growth stages on leaf chlorophyll content and the yield of 'Inerie' variety kidney beans, and to identify the optimal application timing. A Randomized Block Design (RBD) was employed, comparing seven PSB application treatments: a control, single applications at the exponential growth, flower initiation, and pod formation stages, and combined applications (exponential + flower initiation; exponential + pod formation; flower initiation + pod formation; and exponential + flower initiation + pod formation). The results indicated that PSB application at different growth stages significantly influenced both chlorophyll content and kidney bean production. The optimal application time was identified as the flower initiation phase, which significantly increased chlorophyll a content to 8.51 mg/g, total chlorophyll to 14.69 mg/g, and enhanced yield components, resulting in 22.22 pods per plant, 63.06 seeds per plant, and a seed weight of 24.44 g.

Abstract

Green amaranth (Amaranthus viridis L.) is a nutrient-dense leafy vegetable widely consumed for its protein, vitamins (A, B, C), and mineral salts (Ca, P, Fe). This study evaluated the effect of salak-waste compost on the growth and yield of green amaranth. A completely randomized design (CRD) with six single-factor compost rates and four replications was used: D1 = 0 g, D2 = 250 g, D3 = 500 g, D4 = 750 g, D5 = 1,000 g, and D6 = 1,250 g of compost per polybag. The experiment was conducted from March to August in Gununggiana Village, Banjarnegara, Indonesia. Observations included plant height, leaf number, leaf area, root length, whole-plant fresh and dry weights, and root fresh and dry weights; air temperature and relative humidity were recorded as environmental covariates. Data were analyzed using one-way ANOVA at α = 0.05, and significant means were separated with Duncan’s Multiple Range Test (DMRT, 5%). Treatments 1,250 g soil + 750 g compost (D4) and 1,000 g soil + 1,000 g compost (D5) produced the highest mean values for most growth and yield variables (p < 0.05), indicating that these combinations can be recommended to enhance the performance of green amaranth under the conditions of this study.
