Abstract

Green mustard (Brassica juncea L.) is a popular vegetable among Indonesians across all social classes. It has high nutritional value and is rich in vitamins A, B, C, E, and K. This study aims to determine the effect of liquid organic fertilizer (LOF) on the vegetative growth of green mustard (Brassica juncea L.). The research employed analysis of variance (ANOVA) for data analysis, using a Completely Randomized Design (CRD). If significant differences were found, further testing was conducted using the smallest real difference test. The results showed that treatment with 90 ml/L of LOF derived from bamboo leaf waste consistently produced the best growth results over three weeks of observation, with plant height reaching 21.00 cm, the number of leaves reaching 9.67, and the largest leaf width measuring 6.33 cm. These data indicate that applying 90 ml/l of bamboo leaf waste LOF significantly improves plant morphology and health compared to other treatments, suggesting that this treatment can be an effective strategy to increase the productivity of green mustard.

Abstract

The Ciherang rice variety, favored by farmers for its high productivity and resistance to several diseases, has recently shown a decline in performance due to environmental stress and suboptimal adaptation to climate change. This study aimed to determine the extent to which gamma ray exposure affects the growth of Ciherang rice plants. The research employed an experimental method using a single-factor Completely Randomized Design (CRD) with 10 treatments: 0, 50, 100, 150, 200, 250, 300, 350, 400, and 450 Gy, each repeated three times. Consequently, 30 experimental units were established and analyzed using analysis of variance (ANOVA) with SPSS software, followed by Duncan's Multiple Range Test (DMRT) at a 5% significance level. The results demonstrated that gamma-ray radiation significantly affected plant growth and development, with responses varying according to the administered dose. Notably, the 100 ash treatment consistently outperformed others across the three measured parameters: it exhibited the highest germination rate (71%), the most significant plant height at all observation intervals (21.2 cm at 2 weeks after planting [WAP], 51.33 cm at 4 WAP, and 88.33 cm at 6 WAP), and the highest number of tillers (3.66, 6.66, and 14 tillers at the respective time points).

Abstract

Oil palm (Elaeis guineensis Jacq.) is a plantation crop that plays a vital role in the Indonesian economy. This study aims to analyze production costs, income, and the effect of production costs on oil palm farming income in Lobusona Village, Labuhanbatu Regency. The research sample consisted of 30 farmers selected through simple random sampling. Data were analyzed using multiple linear regression. The results show that the average production cost incurred by farmers was IDR 60,600,167 per year, while the average revenue reached IDR 136,266,783 per year. This yield resulted in a net income of IDR 75,666,617 per year, or approximately IDR 24,532,139 per hectare per year. The F-test results indicate that production costs, when considered simultaneously, have a significant effect on income (Sig. 0.000 < 0.05). Meanwhile, the t-test results reveal that fertilizer costs had no significant effect, whereas pesticide and labor costs had a significant adverse effect on income. Conversely, annual production, plant age, and the price of fresh fruit bunches (FFB) had a significant positive effect. The coefficient of determination (R²) of 0.996 demonstrates that 99.6% of the variation in income is explained by the variables included in the model. These findings suggest that the efficient allocation of production costs—particularly for pesticides and labor—is crucial for improving the profitability of oil palm farming.

Abstract

This study aims to analyze the income of oil palm farming businesses in Kogem Village, Marbau District, Labuhanbatu Regency, consisting of production costs, revenue, income, and the revenue-to-cost ratio in oil palm farming. The sampling method used in this study was purposive sampling. This study collected data using primary and secondary data. Data analysis was conducted to calculate costs, revenue, income, and the R/C ratio. The results showed that the R/C ratio for oil palm farming was 3.48, meaning that every Rp. 100.00 additional costs incurred by the entrepreneur will generate Rp. 3.48.00 in revenue. This value is greater than 1, making palm oil farming economically profitable.

Abstract

This study aimed to determine the effect of fertilizer application with a concentration of 5 grams per liter on the vegetative growth of immature oil palm plants (TBM). The study was conducted for 4 weeks with observation intervals once a week, using two treatments: control and application of 5 grams per liter fertilizer, each with 10 replications. Observed parameters included plant height, number of leaves, stem diameter, and leaf length. Data were analyzed using ANOVA test and continued with DMRT test at the 5% level. The results showed that the application of 5 grams per liter fertilizer had a significantly different effect on all growth parameters compared to the control in each observation week. This treatment consistently resulted in higher growth, so it can be concluded that the application of 5 grams per liter fertilizer is effective in increasing the vegetative growth of immature oil palm plants.
