Abstract

Spinach is one of the most important needs for humans, but spinach production in Indonesia has decreased from year to year, so it needs improvement in terms of cultivation technology. The purpose of this study was to analyze the interaction between varieties of spinach and the dose of organic seaweed fertilizer on spinach production; analyzed the dose of organic seaweed fertilizer on spinach production and analyzed the effect of spinach varieties on spinach production. This study was arranged in a factorial randomized block design (RBD), which consisted of two factors, the first factor was the variety of spinach (b) which consisted of two levels, namely green spinach variety Giti Hijau (b1) and red spinach variety Giti Merah (b2), the second factor is the dose of organic fertilizer (d) which consists of 4 levels, namely control (d0), 2 mL/L water (d1), 3 mL/L water (d2), 4 mL/L water (d3). The treatment was divided into 3 blocks as repetition. Data analysis used ANOVA and follow-up test with a DMRT level of 5%. The results showed that the variety of spinach had a significant effect on plant height from 3 to 5 WAP, the number of leaves at 2 WAP and 3 WAP, and the fresh weight of spinach. Fertilizer dosage did not significantly affect plant height, number of leaves, root length, fresh weight, and dry weight of plants . There was no interaction between spinach varieties and doses of organic seaweed fertilizer on all growth parameters and production of spinach.

Abstract

is still limited to household consumption and fresh sales, resulting in low economic value. To increase the added value of coconuts and empower the community, training on Virgin Coconut Oil (VCO) production was conducted for 30 PKK members and 9 village officials. This activity was held on June 24, 2025, at the Simaeasi Village office, using lecture methods, direct practice, and technical assistance. The training covered all stages of VCO production, from coconut selection, grating, coconut milk pressing, fermentation, sedimentation, and the oil refining process. The training results showed that participants experienced a significant increase in knowledge and skills. From 5 mature coconuts, approximately 300 mL of VCO was produced with clear characteristics, coconut aroma, and not rancid. Economic simulations showed that the selling value of VCO is much higher than that of fresh coconuts. Thus, this training successfully increased the community's capacity in coconut processing and opened up new business opportunities based on home industries.

Abstract

This study aims to determine the effect of using manure and furrow irrigation systems on soil water availability and the growth of red chili plants (Capsicum annuum L.). Agricultural land in Indonesia faces many challenges, including declining soil quality and water scarcity, which affect crop productivity. Therefore, it is important to explore solutions based on sustainable agriculture, such as the use of organic fertilizers and efficient irrigation techniques. The research was conducted using an experimental approach in agricultural fields with a quantitative method. The results showed that the application of manure and furrow irrigation significantly increased soil moisture and plant growth compared to the control treatment. These findings are consistent with several previous studies conducted by Sitorus and Tyasmoro (2019), Dewi et al. (2020), and Arifin (2021).

Abstract

The use of mulch is one of the effective soil and water conservation techniques to increase soil moisture and water use efficiency on agricultural land. Mulch functions to suppress the rate of water evaporation from the soil surface, maintain temperature stability, improve soil structure, and support microorganism activity. This literature review aims to understand the effect of mulch use on soil moisture and water conservation based on previous research results. The results of the review show that the provision of mulch, both organic and inorganic, can significantly increase soil moisture by reducing evaporation, increasing water infiltration, and maintaining soil temperature stability. However, excessive mulch thickness can interfere with soil aeration and root respiration processes, so it needs to be adjusted to land conditions and plant types. Therefore, the proper use of mulch can be an important strategy in sustainable soil and water management, especially on agricultural land in tropical and dry areas.

Abstract

Hilidundra Village in Lotu District, North Nias Regency, is one of the areas with a high level of flood vulnerability, especially during the rainy season. This condition hampers local agricultural productivity which is highly dependent on the weather. This study aims to evaluate the effectiveness of the raised bed technique in increasing crop yields on land prone to flooding. The study was conducted using qualitative and quantitative approaches through field observations, farmer interviews, and plant growth experiments on two land systems: using raised beds and without raised beds. The results showed that the raised bed technique was able to increase drainage efficiency, reduce plant damage due to flooding, and significantly increase agricultural productivity. This technique is recommended as a relevant and applicable adaptation solution for agricultural land in tropical areas that are prone to flooding.
