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 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
