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

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

This study aims to analyze the role of vegetative ground cover in reducing erosion rates and increasing water infiltration on sloped lands. The method employed was a field experiment with three treatments: bare land without cover, land planted with vetiver grass, and land planted with leguminous cover crops. The results indicate that vegetative ground cover significantly reduced erosion rates by up to 65% and increased water infiltration rates to more than twice that of bare land. Vetiver grass was found to be more effective than legumes in strengthening soil structure and improving soil physical properties. These findings highlight the importance of utilizing vegetative ground cover as a conservation strategy to maintain soil productivity and preserve water resources. The implementation of vegetative cover is highly recommended for sustainable land management, especially in erosion-prone areas.

Abstract

This study aims to determine the effect of planting time (morning, noon, afternoon) on the early growth of corn (Zea mays L.). A descriptive qualitative method was used, involving field observation, interviews with farmers, and documentation. The findings revealed that planting in the morning led to faster and stronger early growth, marked by earlier germination, fresher leaves, and better root and shoot development. Morning conditions—cooler temperatures and higher humidity supported the seed’s imbibition and early metabolism. In contrast, noon planting showed the weakest performance due to heat and low humidity causing early stress. Afternoon planting yielded moderate results but was still less effective than morning planting. Interviews with farmers confirmed that the morning is considered the best planting time for corn. The study concludes that choosing the right planting time, especially in the morning, is a key factor in supporting early plant development and ensuring successful cultivation in the field.

Abstract

Corn (Zea mays L.) is an important food crop whose successful cultivation largely depends on seed germination. Water plays a crucial role in germination by activating seed metabolism through the imbibition process. This study aimed to examine the effect of soaking duration on the speed and quality of corn seed germination. The research employed a completely randomized design with four soaking durations (0, 6, 12, and 24 hours), each replicated three times. Corn seeds were soaked according to the treatment times, then germinated on wet cotton media and observed for seven days. Parameters measured included germination percentage, radicle emergence time, and seedling length. Results showed that soaking duration significantly influenced all observed parameters. Soaking for 12 hours produced the best results with the highest germination percentage, faster radicle emergence, and optimal seedling length compared to other treatments. Short soaking times were insufficient to stimulate imbibition, while excessively long soaking reduced germination percentage due to oxygen deficiency and risk of seed decay. In conclusion, soaking corn seeds for 12 hours is recommended as the optimal duration to improve germination success. These findings can serve as a guideline for farmers to enhance seedling techniques for corn.
