Abstract

Arugula (Eruca sativa), commonly known as rocket (roquette), is a horticultural crop belonging to the Brassicaceae family and is native to the Mediterranean region, the Middle East, and South Asia. It is widely consumed as a salad ingredient or food seasoning. As public awareness of balanced nutrition continues to increase, the market demand for arugula has grown significantly. Therefore, cultivation innovations are needed to improve arugula productivity, including the use of alternatives to synthetic fertilizers to reduce the high production costs. One promising approach is the application of liquid organic fertilizer (LOF) produced from hydroponic vegetable waste. This study was conducted at the Hydroponic Garden of PT Alam Karya Kahuripan, Bogor Regency, West Java, from July to August 2023. The experiment employed a Randomized Complete Block Design (RCBD) with a single factor, namely the dosage of liquid organic fertilizer derived from hydroponic vegetable waste. Five treatments were applied: P0 = no LOF (control), P1 = 50 mL LOF/L, P2 = 100 mL LOF/L, P3 = 150 mL LOF/L, and P4 = 200 mL LOF/L, with five replications. The observed parameters included plant height, number of leaves, root length, and fresh weight. The data were analyzed using analysis of variance (ANOVA), followed by the Least Significant Difference (LSD) test when significant differences were detected. The results demonstrated that the application of liquid organic fertilizer derived from hydroponic vegetable waste significantly affected all observed variables, including plant height, number of leaves, root length, and fresh weight of arugula. The application rate of 200 mL/L produced the highest values for all growth and yield parameters.

Abstract

Abstract Today, with the advancement of science and technology, all processes in life were made quickly. Efficiency was an important point to continuously achieve and improve in many areas of human life, including agricultural technology. Post-harvest handling to ensure seeds could be processed faster needed to be encouraged by the use of advanced technology to ensure quicker acceptance and usage by farmers. The moisture meter was a more practical and efficient tool for measuring moisture content compared to the oven method. However, according to ISTA Rules, the moisture meter had to be calibrated against the oven method as the reference method. Most seed quality testing laboratories, including the Seed Control and Certification Center (BPSB) and seed producers in Indonesia, used moisture meters for determining moisture content because they were more effective (faster and cheaper) for testing large sample quantities. This research aimed to obtain quick and accurate moisture content determination results using a moisture meter with the correct calibration procedure/technique for the moisture meter and to recommend practical and accurate types of moisture meters for measuring the moisture content of rice seeds. Data from the readings were analyzed using the trumperter plot method. The research results showed that the way to get accurate moisture meter readings was by calibrating and checking the moisture meter against the oven as the reference method. The Kett moisture meter could read the moisture content of rice seeds more accurately than the DMC 500 for measuring the moisture content of rice seeds.

Abstract

Watermelon cultivation in Lombang Village often experienced price fluctuations and crop failures due to pest attacks. This study aimed to identify the factors that motivated farmers in watermelon farming and how these factors influenced their motivation in facing such challenges. The study employed a quantitative approach using multiple linear regression analysis and applied Maslow’s hierarchy of needs theory as a foundation to understand farmer motivation. The variables analyzed included age, education, land area, farming experience, and number of dependents. The population in this study consisted of 50 watermelon farmers in Lombang Village, with a sample of 34 farmers selected using simple random sampling. The results of the analysis showed that education, farming experience, and number of dependents had a significant influence on farmer motivation. Meanwhile, the variables of age and land area did not have a significant effect on farmer motivation

Abstract

Efficient water management is essential for sustainable horticultural production, particularly for high-value crops such as celery (Apium graveolens L.). Conventional irrigation methods often result in significant water losses, emphasizing the need for more precise irrigation systems. Drip irrigation offers improved water efficiency by maintaining soil moisture within the root zone; however, its effectiveness is influenced by irrigation duration. This study evaluated the effects of different drip irrigation durations on the growth and yield of celery and identified the optimal irrigation duration under greenhouse conditions. The experiment was conducted from December 2024 to September 2025 at the greenhouse of the Faculty of Agriculture, University of Borneo Tarakan, using a randomized complete block design with four treatments and six replications. The treatments included manual watering and drip irrigation applied for 10, 15, and 20 minutes. Growth and yield parameters observed were plant height, number of leaves, number of tillers, fresh weight, and dry weight. Data were analyzed using analysis of variance followed by the least significant difference test at the 5% level. The results showed that irrigation duration significantly affected all measured parameters. Drip irrigation applied for 20 minutes consistently produced the highest growth and yield, resulting in the greatest plant height (17.78 cm), number of leaves (11.78), number of tillers (4.33), fresh weight (64.03 g), and dry weight (11.17 g). These findings suggest that a 20-minute drip irrigation duration is optimal for improving celery growth and yield under greenhouse conditions.

Abstract

JC citrus seeds are classified as semi recalcitrant, tending to lose viability relatively quickly after extraction from the fruit. Seed invigoration specifically seed priming is one method used to enhance physiological seed quality. This technique involves soaking seeds in a specific solution for a set duration prior to planting, thereby initiating physiological processes that support subsequent growth. This study aimed to determine the effects of coconut water concentration and soaking duration on the viability of JC citrus seeds. A factorial Completely Randomized Design (CRD) was employed, featuring two factors: coconut water concentration (0%, 25%, 50%, and 75%) and soaking duration (3, 6, and 9 hours). Data were analyzed using Analysis of Variance (ANOVA); significant effects were further analyzed using Duncan’s Multiple Range Test (DMRT) at the 5% level. Observed parameters included germination capacity, vigor index, growth uniformity, and growth rate. The results indicated an interaction between coconut water concentration and soaking duration regarding the seed vigor index, though no such interaction was observed for the other parameters. A 0% concentration with a 6 hour soaking duration yielded the highest vigor index for JC citrus seeds, at 19.7%

Abstract

This study aimed to formulate strategies for improving the productivity of oil palm harvesting workers at PT. Karangjuang Hijau Lestari 1, North Kalimantan, by considering the company’s internal and external conditions. The study employed a quantitative descriptive approach using a census method involving 75 families of harvesting workers. Data were analyzed by identifying economic, social, and work environment factors, which were subsequently assessed using a SWOT matrix to formulate alternative strategies. Strategy priorities were determined using the Quantitative Strategic Planning Matrix (QSPM) based on the Total Attractiveness Score (TAS). The SWOT analysis indicated that the company was positioned in Quadrant I, reflecting a condition in which internal strengths could be leveraged to respond to external opportunities. The QSPM results showed that the SO strategy of strengthening a performance-based incentive system, supported by improvements in performance supervision and monitoring, was the priority strategy, with the highest TAS of 3.84. This strategy represents the main alternative for improving the productivity of harvesting workers, while technical harvesting training and improvements to work equipment, with a TAS of 3.55, served as supporting strategies. Therefore, implementing performance-based incentives accompanied by performance supervision and monitoring can be a primary focus in efforts to improve the productivity of oil palm harvesting workers at PT. Karangjuang Hijau Lestari 1.

Abstract

The kroto weaver ant O. Smaragdina has economic value. However, on Tarakan Island, fulfillment of kroto needs is obtained from hunting/harvesting kroto from nature or without cultivation. The research was conducted on perpetrators of kroto, and local knowledge regarding kroto harvesting activities on Tarakan Island. Survey research was conducted through observations and in-depth interviews with respondents obtained using snowball sampling techniques. Furthermore, the data was analyzed using descriptive analysis. The results of the research show that 5 (five) people act as natural kroto hunters/harvesters on Tarakan Island. Meanwhile, 3 (three) people act as kroto collectors and sell them to be used as bird food and bait for anglers. Local knowledge of kroto harvesters is that they do not harvest all the kroto (not all nests are collected), collect with intensity every day, and move around a minimum cycle of +14 days. They will return to the tree that has been previously marked (previous harvest). Therefore, activities can still be continued, or the results show that the kroto harvesters on Tarakan Island have paid attention to the principles of sustainable use of kroto
