Abstract

The prospect of increasing productivity of drylands as a food provider is very promising, especially for maize production, which plays an equally important role as a food crop compared to rice. However, in general, the quality of drylands in Indonesia is relatively low. This study aims to further investigate the application of dolomite combined with inorganic fertilizers such as rock phosphate, K and N fertilizers to improve the quality of dry soil, which has the potential to increase maize productivity. The research was conducted at the Seasonal Crop Field of Lampung State Polytechnic from October to December 2022. The study used an experimental method with a Completely Randomized Block Design (CRBD) with 6 treatments and 6 replications. The treatments tested included: k0: without fertilizer; k1: KCl fertilizer dose of 50 kg/ha; k2: KCl fertilizer dose of 100 kg/ha; k3: KCl fertilizer dose of 150 kg/ha; n1: Urea fertilizer dose of 200 kg/ha; n2: Urea fertilizer dose of 250 kg/ha. The results of the study showed that the treatment of KCl fertilizer dose of 100 kg/ha significantly showed the best response on the average parameter of Wet Grain Weight per Cob, Dry Grain Weight per Cob, and Weight per Cob Without Corn Husk of Corn Plants

Abstract

The presence of weeds is a significant factor that contributes to the decline in maize yield. To reduce yield loss, appropriate weed control methods must be applied. The first step in determining these methods is to identify weed dominance and diversity. This study aims to identify the dominance and diversity of weeds in three corn planting systems: conventional, jajar legowo 1:2, and 1:3 spacing. The research was conducted at the Teaching Farm Polinela Organic Farm in Lampung Province from November to December 2023. Vegetation analysis was performed using a 0.5 m2 quadrant randomly placed on 10 plots of land. The dominance value of weeds was determined using the Summed Dominance Ratio (SDR) value, while the diversity of weeds was measured using the Shanon-Wiener index value (H'). The study found that the conventional field had 9 weed species, the 1:2 legowo field had 8 weed species, and the 1:3 legowo field had 5 weed species. Ageratum conyzoides was the dominant broadleaf weed species in both the conventional corn field and jajar legowo 1:2, while Asystasia gangetica dominated the jajar legowo 1:3 corn field. The weed diversity index analysis results for the three corn planting systems fall into the medium category. Specifically, the results are 2.12 for conventional corn fields, 1.94 for 1:2 jajar legowo corn fields, and 1.3 for 1:3 jajar legowo corn fields.

Abstract

The availability of adequate water is one of the key factors in supporting increased food productivity, especially in areas that have large agricultural potential such as the Warsansom Watershed (DAS), West Papua. This research aims to predict water availability in the Warsansom watershed using the Soil and Water Assessment Tool (SWAT) model. The SWAT model was chosen because of its ability to simulate hydrological processes, erosion and land use dynamics in a spatial-temporal manner. The data used includes rainfall, temperature, topography, soil type and land use patterns. The analysis results show that the average annual rainfall is 322 mm/year, with an annual average temperature of 26.49°C. The Warsansom watershed area is dominated by secondary dryland forest (78.69%) which contributes significantly to groundwater infiltration and recharge. Regional delineation resulted in 33 sub-watersheds with a total area of ​​144,280 ha, as well as 273 hydrological response units (HRU) which became the basis for identifying critical areas in water management. SWAT simulations reveal potential risks of surface runoff in areas with steep slopes (36.53%) that require conservation interventions to reduce erosion and sedimentation. This research recommends data-based strategies for optimizing water resource management, including improving irrigation infrastructure, developing cropping patterns that are adaptive to water availability, and mitigating the impacts of climate change. By utilizing SWAT simulations, it is hoped that food productivity in the Warsansom watershed can increase sustainably, supporting food security in the West Papua region

Abstract

ntensive agricultural activities in rice cultivation impact increasing waste, especially straw. Unfortunately,straw contains cellulose and lignin, which are difficult to decompose. This study examines the effect of adding biologicalagents on compost quality from rice straw waste. The study used a Randomized Block Design (RBD) with four treatmentsand six replications, including T0: control (without biological agents), T1: POF catalyst, T2: Bacillus sp., T3: Trichodermasp. Observation variables for compost quality include analysis of temperature changes, pH value, water content, andchemical analysis, including the content of total macronutrients nitrogen, phosphorus, and potassium. Quantitative datawere analyzed statistically using ANOVA and the LSD test p <0.05. The findings indicated that incorporating biologicalagents in rice straw composting markedly enhanced the quality of the resulting compost. Utilizing biological agents,particularly the Trichoderma treatment, led to a notable enhancement in compost quality. The macronutrient content ofnitrogen (N) increased by 3.60%, phosphorus (P) by 0.49%, and potassium (K) by 1.67%. This increase could havesignificant implications for the composting process. Additionally, an increase in temperature, reaching 50-60°C,significantly impacts the composting process, collectively affecting microorganisms and facilitating the decomposition oforganic matter. Furthermore, the thermophilic phase in Trichoderma treatment accelerates decomposition, thus offering apotential solution for faster composting

Abstract

Composting organic waste is significantly gaining attention as a sustainable and environmentally friendly material. This is because the use of microorganisms or microbial consortia in the composting process can enhance the quality of compost. Therefore, this study aimed to examine the impact of microbial consortia on cow manure composting efficiency and nutrient content. The experiment was conducted at the Polinela Organic Farm, Department of Food Crop Cultivation. A randomized block design was used with multiple treatments combining fresh cow manure and microbial inoculants, including catalyst, Bacillus, and Trichoderma. The parameters evaluated were the effects of water content, pH, temperature fluctuations, and macronutrient levels on composting, including nitrogen, phosphorus, and potassium. The results showed that microbial consortia significantly improved composting parameters such as moisture retention and temperature as a function of higher doses?of the inoculum. The highest total nitrogen (3.6%) and potassium (1.67%) content were obtained from Trichoderma treatment,?while the highest phosphorus (0.47%) content was obtained from Bacillus treatment. This?implied that microbial consortia could improve the quality and availability of composted nutrients in addition to the effectiveness of agricultural waste management and soil fertility practices. However, more research should be conducted?to determine the optimal microbial mixtures for various conditions of composting and the quality of the best compost produced.

Abstract

The agricultural sector plays a strategic role in food security and environmental sustainability; however, it faces challenges such as declining productivity and pollution due to synthetic chemicals. This study aims to identify antagonistic fungi from organic lands and test their effectiveness in controlling Fusarium sp. pathogens as part of integrated pest management. The methods employed include exploration, isolation, identification, and antagonistic fungi testing on Potato Dextrose Agar (PDA) media. The results revealed four types of identified fungi, including light green, brown, and black, which belong to the Aspergillus sp. and dark green is Trichoderma sp. species. The light green antagonistic fungus effectively suppressed the growth of Fusarium pathogens by 57.84%, while the dark green fungus showed a suppression rate of 32.32%. This study emphasizes the potential of antagonistic fungi as effective biocontrol agents in sustainable agriculture.
