Abstract

This research aims to discover the psychological state of farmers in the agricultural cultivation of food crops during the COVID-19 pandemic. It is a descriptive explorative study which explores the farmers’ opinions regarding their agricultural activities during the COVID-19 pandemic which reached its peak between March and June 2020. During this period, a Large Scale Social Distancing (LSSD) system was enforced in some areas. The data collection was conducted in June 2020 before the implementation of the new normal, involving 634 respondents which spread across 40 districts throughout Java. Throughout the COVID-19 pandemic period, almost all farmers continued to carry out their agricultural activities. Some farmers had implemented the health protocols. According to most farmers’ opinions, doing the agricultural activities made them healthier. With regard to COVID-19, most farmers behave normally, while the rest feel worried. Agricultural extension activities are constrained and hampered by the implementation of physical and social distancing, especially large-scale social restrictions. Seeing the psychological condition of the farmers, where most are continuing to cultivate food crops and only slightly worried about the COVID-19 pandemic, gave hope for the sustainability of agricultural production in the new normal period.

Abstract

The Klampok Sub-watershed flows in the Semarang Regency, Central Java, Indonesia, located in the upstream part of the Jragung Watershed, used as a source of irrigation. Klampok Sub-watershed experiences environmental pressures in the form of decreasing water quality because of various human activities. For this reason, this study aims to determine the changes in the water quality and pollution index of the Klampok Sub-watershed in 2016 and 2020. The water quality observations were carried out in 2020 utilizing the Total Suspended Solids (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Nitrate, Zinc (Zn) and Copper (Cu) parameters. The laboratory analysis results were compared with water quality standards based on Government Regulation Number 22 of 2021 and the status of water quality based on the pollution index method under the Decree of the Minister of the Environment Number 115 of 2003. The study results showed a change in the quality and index of water pollution in 2016 and 2020. The study results revealed a decrease in the value of water quality on the parameters BOD, COD, Zn and Cu, which indicated that the water quality was improving. Moreover, the Klampok Sub-watershed pollution index decreased in 2016 and 2020 so that the Klampok Sub-watershed had quality criteria for lightly polluted water to moderately polluted to lightly polluted at each sampling point. Therefore, several efforts to control pollution and management of the Klampok Sub-watershed, such as community outreach, water quality monitoring and industrial compliance, are expected to improve so that the Klampok Sub-watershed's sustainability can provide various benefits to the community.

Abstract

Bagasse, one of the largest agricultural wastes with suboptimal utilization, could improve Entisols in the tropics by enhancing soil fertility and crop productivity. This study aimed to determine the changes in humic substances and nutrient levels in Entisols and their effects on shallot yield. The study was designed using a completely randomized design, consisting of four treatments of organic matter combinations with NPK fertilizer, four single organic matter treatments, one standard NPK fertilizer dose, and one control. Each was replicated three times. The results showed that using bagasse improved soil conditions by increasing C content and nutrient levels in the soil, enhancing nutrient absorption by plants, and consequently boosting crop yields. The biochar + bagasse compost (2:4) (bio-compost) + NPK resulted in high soil organic C, humic acid, fulvic acid, nutrient availability, and plant nutrient levels, which were comparable to the manure treatment, and significantly increased shallot yield in Entisols. The findings of this study could support the development of nutrient management strategies utilizing bagasse as a potential soil amendment for Entisols.

Abstract

The ever-increasing demand for soybeans has not been matched by increased yields. This is partly due to farmers not fertilizing properly. Many farmers apply urea, SP36, KCl, or compound NPK fertilizers at doses that are inappropriate for the plants' needs. Many even fertilize haphazardly. Appropriate fertilization methods are needed. This study aims to determine the effect of some of fertilization methods on soybean growth and yield on Alfisol. This study used a completely randomized block design (RCBD) with five treatments and five replications. PT0 (no fertilizer), PT1 (Farmer's Method: Urea, SP36, and KCl), PT2 (Balanced Fertilization Method: Urea, SP36, and KCl), PT3 (Farmer's Method: NPK Compound Fertilizer), PT4 (Balanced Fertilization Method: NPK Compound Fertilizer). The results of this study show that inorganic fertilizers given in a balanced manner can increase soybean yields from 2.28 g/plant to 13.82 g/plant. The results of this study indicate that the best treatment method, PT2 (Balanced Fertilization Method: Urea, SP36, and KCl), is able to support plant growth and increase soybean yields.
