Abstract

Guava (Psidium guajava L.) is a tropical plant that holds significant popularity and economic value in Indonesia. Despite its benefits, many Indonesians still face challenges in successfully cultivating guava seeds. Traditionally, guavas are propagated from seeds, which often results in lower-quality fruit. Seed-grown trees may take longer to bear fruit, and the fruit produced may not resemble that of the parent plant. This study aims to evaluate the success rate of guava propagation using stem cuttings treated with two different chemicals—Root Up and Liquinox Start—as well as a natural alternative, shallot extract. The cuttings were treated uniformly across all treatments, and the growth parameters observed included the number of shoots, the number of leaves, and the length of the shoots over two months from April 20 to June 22, 2025. The results indicated a significant difference between the three treatments. Root Up treatment produced the longest shoot growth on average, while Liquinox Start also showed a relatively high rate of shoot development. Shallot extract, a natural alternative, also yielded promising results, offering an environmentally friendly and easily accessible option for guava propagation. While chemical treatments, such as Root Up, led to optimal results in terms of shoot, leaf, and shoot length development, the use of shallots demonstrates that natural ingredients can also provide a sustainable and effective approach to guava propagation. Based on the findings, Root Up is recommended for accelerating guava plant growth, but shallot extract presents a viable, eco-friendly alternative.

Abstract

Honey water guava (Syzygium aqueum) is one of the newest high-quality commodities and is increasingly being cultivated by farmers in various regions. This study aimed to evaluate the effects of applying organic plant growth regulators (PGRs) derived from sprout extracts at different doses on the growth of water apple (Syzygium aqueum) plants. A completely randomized design (CRD) with a single treatment factor was employed. The results demonstrated that the 60 mL treatment of ZPT Organic Benefits Extract was the most effective in promoting plant growth, achieving an average height of 10.8 cm and five shoots at 4 weeks after planting (WAP), compared to the control treatment, which reached only 8 cm in height and two shoots. These findings indicate that the 60 mL dose of organic PGR extract from sprouts significantly enhanced growth and stimulated shoot development relative to the other treatments.

Abstract

Oil palm has significant potential as a strategic commodity to enhance farmers' income while contributing substantially to Indonesia's foreign exchange earnings. This study aims to examine the role of farmer groups in supporting the productivity of smallholder oil palm farmers. The research was conducted in Tebing Linggahara Baru Village, Bilah Barat District, Labuhanbatu Regency. An associative research design with a descriptive-quantitative survey method was employed. Data were collected through questionnaires and documentation from 30 farmer respondents. Statistical analyses included partial difference tests (t-tests), significance tests (F-tests), and coefficients of determination (R²), which were processed using SPSS. The findings indicate that farmer groups play a crucial role in enhancing the productivity of oil palm farmers.

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

Oil palm (Elaeis guineensis Jacq.) is one of Indonesia's leading plantation commodities and plays a strategic role in the national economy. The purpose of this study was to determine the effectiveness of EFB compost as an alternative source of potassium, analyze its effect on potassium nutrient uptake, and assess its impact on oil palm yields at PT Evans Group. This research method used a field experiment approach by comparing two treatments: a control treatment without EFB compost and a treatment with EFB compost at a dose of 50 kg per plant. The results showed that compost application had a positive effect on plants, as indicated by increased leaf potassium content in the compost treatment compared to the treatment without compost. Although the difference was not significant, these results indicate that compost plays a role in increasing potassium availability and uptake by plants, thus supporting better plant growth.

Abstract

Oil palm (Elaeis guineensis Jacq.) is a tropical plantation crop with high economic value and is one of Indonesia's mainstay commodities. The purpose of this study was to determine the level of basal stem rot (Ganoderma boninense) infestation in oil palm plants at the Pangkatan Plantation of PT. Evans Group, the magnitude of the resulting fresh fruit bunch (FFB) yield losses, and the relationship between disease severity and the decrease in FFB yield. The research method used was a survey method with a quantitative descriptive approach. The results showed that the level of ganoderma infestation in Block A1 was relatively low at 8.7%, but had a significant impact on oil palm productivity. Trees attacked by ganoderma produced lower fresh fruit bunch (FFB) weights than healthy trees, thus indicating that plant health significantly affects production results.

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 aims to analyze the intensity of rhinoceros beetle (Oryctes rhinoceros) attacks on oil palm leaf sheaths during the Mature Plant (TM) phase at PT. Binanga Karya. The rhinoceros beetle is a major pest of oil palm plants, reducing vegetative growth and potentially impacting crop productivity if not properly controlled. This study was conducted through a field survey using purposive sampling in mature plant blocks. Observed parameters included the number of infested plants, the number of leaf sheath holes, and the level of leaf sheath damage as an indicator of pest attack intensity. The data obtained were analyzed descriptively and quantitatively by calculating the percentage of attack intensity based on the ratio between the number of infested plants and the total sampled plant population. The results showed that rhinoceros beetle attack intensity was mild to moderate, with variations in the level of damage between plant blocks. The leaf sheath damage found generally consisted of bore holes and bite marks at the base of the sheath. Although the attack has not yet caused a significant decrease in production, the presence of this pest still requires vigilance because it has the potential to increase the level of damage if the population is not controlled. Therefore, appropriate and sustainable pest control efforts are needed to maintain plant health and the stability of palm oil production.
