Oil palm (Elaeis guineensis Jacq.) is an important plantation commodity that makes a significant contribution to Indonesia's economy. One of the macro nutrients that plays a role in supporting plant growth is potassium (K), which is involved in various physiological processes. The effectiveness of nutrient utilization is not only determined by the amount of fertilizer applied but also influenced by the application method, especially during the early seedling phase. This study aims to examine the growth response of oil palm seedlings to variations in KCl fertilizer doses and different fertilizer application methods during the pre-nursery phase. The experiment was arranged using a Factorial Randomized Block Design (RBD) with two treatment factors, namely KCl fertilizer dose and fertilizer application method, each with three replications. The KCl doses consisted of five levels, while the application methods included watering, broadcasting, and localized application (pocket). The observation data were analyzed using analysis of variance and followed by Duncan Multiple Range Test (DMRT) at a 5% level if there were significant differences. The results of the study showed that there was no interaction between the dose of KCl fertilizer and its application method on all observed oil palm seedling growth parameters.

Stunting remains one of the major chronic nutritional problems in Indonesia, including in Oesapa Village, Kelapa Lima District, Kupang City, East Nusa Tenggara Province. This condition is not only caused by inadequate nutritional intake but is also closely related to chronic infections resulting from poor hygiene and sanitation, particularly intestinal parasitic diseases. To reduce the risk of parasitic infections and improve children’s nutritional status, preventive efforts through education and health promotion are essential.This community service activity aimed to increase public awareness and knowledge, especially among parents and caregivers of stunted children, regarding the importance of maintaining hygiene and sanitation to prevent intestinal parasitic diseases. The methods used included participatory approaches such as interactive lectures, group discussions, and practical demonstrations of clean and healthy living behavior (PHBS), food hygiene, clean water management, and household waste disposal. Evaluation was conducted using pre-test and post-test instruments to measure changes in participants’ knowledge.The activities, carried out from May to September 2025 in Oesapa Village, showed a significant improvement in community understanding of hygiene and sanitation practices. Participants demonstrated greater commitment to maintaining environmental cleanliness and adopting healthier daily behaviors. Continuous educational efforts and multisectoral support are needed to help reduce the prevalence of stunting in the region

Indonesia is the world’s second largest contributor of plastic waste entering the oceans, where it degrades into microplastics smaller than 1 micron. The use of bioplastics is therefore essential to mitigate environmental pollution. One promising alternative is starch–cellulose blend bioplastic derived from empty fruit bunches (EFB) of oil palm. Indonesia produces about 56.35 million tons of EFB annually, containing approximately 40% cellulose, which makes it a potential raw material for bioplastic production, although commercialization has not yet been realized. Environmentally, converting EFB into bioplastics within the palm oil value chain represents a sustainable waste recycling strategy that transforms solid residues into higher-value products. In this design, soda cooking technology is employed to extract cellulose from EFB, utilizing about 16% of waste from a crude palm oil (CPO) mill with a capacity of 30 tons of fresh fruit bunches (FFB) per hour. The starch–cellulose blend bioplastic pellets are formulated using gelatinized cassava starch as the polymer matrix, glycerol as a plasticizer, polyvinyl alcohol (PVA) as a stabilizer, and cellulose as a filler. The designed production capacity of the EFB-based starch–cellulose bioplastic plant is 16,500 tons per year. This bioplastic industry is expected to contribute positively to achieving eight Sustainable Development Goals (SDGs), including Goals 1, 8, 9, 12, 13, 14, 15, and 17, thereby supporting Indonesia’s commitment to sustainable industrial development and a cleaner environment.

This study comprehensively evaluates the quality of biomass briquettes produced from blends of coconut shell charcoal and sengon sawdust, using both carbonized and non-carbonized materials. Composite briquettes were fabricated with varying compositions and characterized through proximate analysis, calorific value, density, and burning rate measurements to determine their suitability as solid fuel. The results indicate that adding non-carbonized sawdust increases volatile matter content and burning rate but reduces the calorific value of the briquettes. In contrast, incorporating up to 10% carbonized sawdust significantly improves the calorific value to 6119.2 cal/g, approaching that of pure coconut shell charcoal (6352.2 cal/g), while maintaining a relatively high burning rate. Briquettes containing carbonized sawdust also exhibit low ash content, below 3%, and moisture content under 8%, meeting standard solid fuel quality requirements. These findings demonstrate that a strategic combination of carbonized and non-carbonized materials can produce hybrid biomass briquettes with optimized thermal performance, providing a promising, sustainable, and environmentally friendly alternative fuel for domestic and industrial applications.

The problem with the coconut grater machine is that the machine has decreased performance after being used for several years, especially in the mechanical components (electric motor, V belt, Pulley, grater knife, hopper) and its electricity. The purpose of maintenance and repair planning is to obtain costs, maintenance and repair schedules for the period 2026, and the ratio of maintenance costs to profit. The maintenance and repair planning method includes collecting previous maintenance data, applying the inspection-replace-repair-overhaul (IRRO) method, evaluating component conditions, predicting component lifespan, predicting labor costs, predicting supporting equipment that will be used in maintenance, predicting the time to replace spare parts or reinstall repaired components, estimating maintenance and repair costs for the 2026 period, and calculating the maintenance cost to profit ratio. The results of maintenance and repair planning obtained maintenance costs for the 2026 period were IDR 957,000 with an estimated coconut grater machine rental rate of IDR 10,000/hour which has the potential to be rented for 900 hours/year, and the maintenance cost to profit ratio was 10.6% which implies that the coconut grater machine with a capacity of 15 kg/hour is still prospective and feasible to use for the next few years.

Muaro Jambi Regency is one of the main centers of smallholder oil palm plantations that plays an important role in the economy of Jambi Province through its contribution to crude palm oil (CPO) exports and tax revenues. This study aims to analyze farmer characteristics and the effects of land area (X1), plant age (X2), forest and land fire impacts (X3), labor (X4), and fertilizer use (X5) on the production of fresh fruit bunches (FFB) of smallholder oil palm in Kumpeh District. This study used a descriptive quantitative approach with primary data collected through a survey of 139 respondents and analyzed using multiple linear regression with the help of SPSS version 25. The results show that the average characteristics of farmers include an age of 44 years, an average of 2 dependents, land area of 2 hectares, plant age of 10 years, high fire impact scores, labor use of 2 workers, fertilizer use of 1,120 kg, and production of 20,000 kg. The regression results indicate that land area, plant age, and fertilizer use have a significant effect on production, while labor and forest and land fires do not have a significant effect on smallholder oil palm production.

This study aims to determine the effect of the interaction between the duration of immersion of coconut water plant growth regulators and manure on the growth of guava cuttings (Syzygium aqueum). This study used a Factorial Randomized Block Design (RAK) consisting of 2 factors with 48 plots, namely: The first factor is the duration of immersion of coconut water plant growth regulators which is given the symbol 'A' which consists of 4 levels of treatment, namely A0: without immersion, A1: 3 hours, A2: 6 hours, A3: 9 hours. The second factor is manure which is given the symbol 'S' which consists of 4 levels of treatment, namely S0: 0 g / polybag, S1: 50 g / polybag, S2: 100 g / polybag, S3: 150 g / polybag. So there are 16 combinations consisting of 3 replications. The parameters observed in this study are the age of shoot emergence, number of shoots, shoot length, leaf length, number of leaves, percentage of survival. The results of the study showed that the duration of immersion in young coconut water with growth regulators and the application of cow dung fertilizer significantly affected the growth of water apple (Syzygium aqueum) cuttings. The results showed that the duration of immersion in young coconut water with growth regulators and the application of cow dung fertilizer only significantly affected the number of shoots and leaves observed in the ninth week.

This study aims to analyze the implementation of mangrove rehabilitation policies after Cyclone Seroja in West Oesapa Village, Kupang City, using Merilee S. Grindle's policy implementation theory and the principles of good governance. Mangrove rehabilitation is a crucial step in the recovery of coastal ecosystems affected by disasters, but in practice it often faces various obstacles, both in terms of institutions, coordination between actors, and community participation. This study uses a descriptive qualitative approach. Data collection techniques were carried out through in-depth interviews with nine informants consisting of representatives of government agencies (DLHK, BKSDA), field supervisors, NGO administrators, RT heads, and local communities. Data analysis was carried out by referring to two main variables of Grindle's theory, namely policy content and implementation context, which were then combined with governance principles such as coordination, participation, transparency, effectiveness, and accountability. The results of the study indicate that the implementation of the mangrove rehabilitation policy in West Oesapa does not fully reflect the principles of good governance. Coordination between actors is not optimal, community participation is still passive, and post-implementation monitoring mechanisms have not been implemented. The dominance of technical implementers and minimal community involvement in planning are major obstacles to achieving program sustainability. Therefore, strengthening collaborative governance and community empowerment is needed to ensure effective and sustainable mangrove rehabilitation.

This study aims to develop, validate, and test the effectiveness of a scaffolding-based e-module integrated with educational games on the topic of market equilibrium to improve students’ problem-solving skills in economics learning. The research utilized the ADDIE development model, which includes the stages of analysis, design, development, implementation, and evaluation. A total of 72 students from SMA Negeri 1 Kelapa participated in the study, divided into experimental and control groups. Data were collected through validation questionnaires, pre-tests, and post-tests. The results showed that the e-module obtained a very high level of feasibility, with average validation scores of 3.86 from material experts, 3.88 from media experts, 3.95 from teachers, and 3.49 from students, indicating that the product met the quality criteria for instructional media. Furthermore, effectiveness testing revealed that students in the experimental class achieved an N-Gain score of 0.56, categorized as moderate, which was significantly higher than the control class score of 0.30. These results suggest that the scaffolding-based e-module integrated with educational games is both feasible and effective in enhancing students’ problem-solving skills and learning engagement in economics education.

This study aims to determine the effect of motivation and physical work environment on employee performance at the Pegadaian Branch Office in Kelapa Dua, Depok. The method used is a quantitative approach with the distribution of questionnaires to 33 respondents as samples. This study uses a saturated sampling technique. The data analysis was conducted using IBM SPSS version 21 through validity tests, reliability tests, classic assumption tests (normality, multicollinearity, heteroscedasticity), multiple linear regression tests, T tests, F tests, and determination coefficients. The results show that both motivation and physical work environment partially have a positive and significant effect on employee performance. Motivation contributes 50.4%, while the physical work environment contributes 50.9%. Simultaneously, both motivation and physical work environment together have an influence on employee performance of 63.8%. Meanwhile, the rest is influenced by other factors that were not examined in this research. Based on the results of this study, it can be concluded that increasing motivation and improving the physical work environment can effectively enhance employee performance. These findings are expected to serve as a reference for management in making human resource policy decisions. Future researchers are encouraged to increase the number of respondents and introduce other variables to obtain more detailed analysis results.

The manufacturing industry in Indonesia has experienced significant growth. This increase has also impacted the demand for motorcycle spare parts. Currently, brake pads are composed of asbestos, which makes them prone to overheating and failure when reaching high friction temperatures. Therefore, an alternative brake pad material is an organic material mixed with coconut shell powder and bamboo fiber. This study aims to analyze the wear and hardness levels of motorcycle brake pads made from coconut shell powder and bamboo fiber. The study used varying ratios of coconut shell powder, bamboo fiber, and epoxy resin: 40:30:30, 35:35:30, and 30:40:30. Eighteen specimens were tested. Wear testing was performed using an Ogoshi Wear Tester, while hardness testing was performed using a Brinell hardness tester. The test results showed that the smallest wear rate on brake pads with variations of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin was 0.001107984 mm3/kg.m. The highest hardness level was also in the variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin at 63,0024 kg/. So it can be concluded that the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the lower the wear rate. If the greater the percentage of coconut shell powder and the smaller the percentage of bamboo fiber, the higher the hardness level. So it can be concluded that a good brake pad variation is a variation of 40% coconut shell powder, 30% bamboo fiber and 30% epoxy resin.

Oil palm (Elaeis guineensis) is a major tropical commodity in Southeast Asia that plays an important role in the global economy, especially as a raw material for the food, cosmetics, and bioenergy industries. West Kalimantan Province is one of the regions with the largest oil palm plantations in Indonesia, where its area increased from 1,166,282 Ha in 2020 to 1,449,274 Ha in 2022. Landak Regency contributes 119,326 Ha, but its productivity is still relatively low with a total production of 184,592 tons or around 1.54 tons/Ha. PTPN IV Ngabang in Landak Regency as one of the largest palm oil companies in the area also faces the problem of low productivity, thus hindering harvest rotation and the achievement of daily targets. This study aims to describe the productivity of oil palm harvester labor and find out what factors affect the productivity of oil palm harvester labor in PTPN IV, Ngabang District, Landak Regency. The method uses qualitative as an approach in finding answers with a sample of 78 respondents. The variables in this case study are labor productivity (Y) and independent/independent variables (X), namely age, working period, family dependents, mileage, and education. The data analysis technique used in this case study is analysis on multiple linear regression. The results of the study concluded that the productivity of oil palm harvesters in PTPN IV Ngabang averaged 1200,71 kg/day. Simultaneously, age, family dependents, working period, mileage, and education affect the productivity of oil palm harvester labor at PTPN IV Ngabang. Partially, the factor that greatly affects the productivity of the oil palm harvester workforce at PTPN IV Ngabang is the age factor of the worker and working period. Meanwhile, the factors of family dependents, distance traveled and labor education partially did not have a significant effect.

A partnership agreement is a form of business collaboration, either directly or indirectly, that is established based on the principles of mutual need, mutual trust, mutual reinforcement, and mutual benefit. Such partnerships generally involve Micro, Small, and Medium Enterprises (MSMEs) working with larger businesses in order to create a fairer and more sustainable business relationship. However, in practice, the implementation of partnership agreements often does not reflect these fundamental principles. This is also evident in the nucleus-plasma scheme within the palm oil plantation sector, where the relationship between the nucleus companies and plasma farmers tends to show an imbalance of bargaining power. This study aims to examine the application of partnership principles in the implementation of nucleus-plasma agreements in palm oil plantations, viewed from the perspective of prevailing legislation, particularly the Law on Micro, Small, and Medium Enterprises (MSME Law). The findings indicate that the application of partnership principles has not yet been fully implemented consistently. The partnership relationship remains unequal and is largely dominated by the nucleus companies, creating a sense of injustice for plasma farmers. In terms of supervision, the Indonesian Business Competition Supervisory Commission (KPPU) plays a crucial role in ensuring that partnership agreements are carried out in line with these principles. One of the measures taken is monitoring the implementation of behavioral change commitments by business actors. KPPU ensures that nucleus companies do not abuse their dominant position and continue to provide fair opportunities for plasma farmers. Therefore, this study highlights the importance of strengthening oversight and enforcing regulations so that the objectives of nucleus-plasma partnerships in palm oil plantations can truly be realized in accordance with the principles mandated by law.

Oil palm is a leading commodity that makes a major contribution to Indonesia’s economy, yet a significant productivity gap remains between actual and potential yields. A principal cause is suboptimal water management, which leads to flooding during the rainy season and drought in the dry season. This study develops a Conceptual Design (CD) for water management to map existing problems, analyse root causes, formulate improvement measures, and present a macro-level cost estimate for the study site. The research was conducted at an oil palm plantation in East Kalimantan anonymized as “PT XYZ.” The site was selected due to recurrent flooding and a recent change in ownership that limited data availability, making it well-suited for a CD-stage assessment. The objective is to identify water management issues and propose effective recommendations. A quantitative approach integrates primary data from field observations and measurements with secondary data. The analyses cover flood problem assessment, Water Management Zoning (WMZ/ZPA), rainfall analysis, hydrology, hydraulics, improvement proposals, and macro cost estimation. Results indicate that challenges are driven by swampy land conditions and inadequate channel and hydraulic structure capacity. Micro-watershed delineation using DEMNAS identified four ZPAs totalling 479–4,061 ha. Design rainfall was derived from CHIRPS satellite data using a log-normal distribution. Hydrologically, peak discharges range from 3.87–22.58 m³/s for the 2-year return period and 4.46–26.31 m³/s for the 5-year return period. Hydraulically, the proposed dimensions for rivers, outlet drains, carrier drains, and field-edge drains are 4×3×2 m to 9×7×3 m (T=2 years) and 4×3×2 m to 10×8×3 m (T=5 years), while collection and main drains are proposed at 3×2×2 m for both return periods. The total estimated investment for the 5-year design scenario is IDR 27,999,263,000.

This study aims to analyze the effectiveness of the Hatch and Carry Center (H&C) in increasing the population of Elaeidobius kamerunicus pollinating weevils, fruit set levels, and Fresh Fruit Bunch (FFB) productivity in oil palm plantations at Division 6 Estate SGT 02, PT Kayung Agro Lestari, West Kalimantan. The research was conducted over six months, from July to December 2024, using a quasi-experimental comparative design. The period without H&C (July–December 2023) served as the control, while the period with H&C (July–December 2024) was treated as the intervention, allowing for a clearer analysis of differences before and after program implementation. Primary data were collected through monthly field observations on the number of male and female flowers, weevil populations, fruit set levels, and parthenocarpic fruits, providing consistent information on plant reproductive dynamics. In addition, in-depth interviews and Focus Group Discussions (FGDs) with stakeholders were conducted to identify supporting and inhibiting factors during implementation. Secondary data on FFB production were obtained from company harvest records in both periods to compare productivity trends. Quantitative data analysis employed the t-test to examine significant differences between the control and treatment periods, while qualitative data were thematically analyzed to explore the dynamics of program execution. The combination of both approaches is expected to provide a comprehensive understanding of the effectiveness of H&C as an innovation in oil palm pollination management.

This study aims to examine the effectiveness of attractants on the activity of the pollinating beetle Elaeidobius kamerunicus and its impact on the efficiency of pollination and palm oil (Elaeis guineensis) production at PT Menthobi Makmur Lestari, Lamandau Regency, Central Kalimantan. The study was conducted from May to July 2025 using a factorial randomized block design with two factors: topography (flat 0–8% and hilly 15–25%) and attractant doses (0, 1, 2, and 3 ml/ha) with three replications.The parameters observed included the frequency of E. kamerunicus visits to female flowers and the percentage of fruit set. The results showed that the topography factor, attractant dose, and their interaction significantly affected the number of E. kamerunicus visits and fruit set (p < 0.01). The combination of flat land with high attractant doses resulted in the highest visits (69.04 beetles/spike) and maximum fruit set (75.11%), while the hilly land without attractants showed the lowest results (34.60 beetles/spike; 61.22%). The application of attractants increased fruit set by more than 20% compared to the control, leading to an increase in bunch weight (BJR) of approximately 5.67 kg/bunch, additional production of about 1,151 kg FFB/ha per 1.5 months, and a potential income of Rp 3,683,200/ha, far exceeding the application cost of Rp 211,638/ha. These results indicate that the use of attractants is an effective and efficient agronomic strategy to improve palm oil productivity. Thus, attractants have proven to significantly enhance pollination efficiency and palm oil production, providing substantial economic benefits to farmers and supporting the sustainability of palm oil plantations. This approach offers an applicable and sustainable solution for agricultural practices, which can be applied to various locations with similar topographical conditions.  

This research discusses the effect of coconut dregs compost (Cocos nucifera L.) on the growth and yield of tomato plants (Solanum lycopersicum L.) cultivated using polybag media. This research is motivated by the importance of utilizing organic waste, especially coconut dregs, which has not been utilized optimally. Coconut dregs contain organic materials and nutrients that have the potential to increase soil fertility and improve the structure of the planting medium, so it is expected to support the vegetative and generative growth of tomato plants. The research design used was a Randomized Block Design (RBD) with six treatments and four replications. The treatments given were different doses of coconut dregs compost, namely P0 (control without compost), P1 (100 g/polybag), P2 (200 g/polybag), P3 (300 g/polybag), P4 (400 g/polybag), and P5 (500 g/polybag). The parameters observed included plant height, stem diameter, fresh weight, number of fruits per plant, root length, and estimated yield per hectare. The results showed that the application of coconut pulp compost significantly affected several growth parameters, such as plant height, stem diameter, and fresh weight. However, no significant effect was found on the number of fruits per plant or yield per hectare. The most prominent response was seen in the root length parameter, which showed a significant increase with increasing compost dosage. From the observations, the best treatment was at a dosage of 300 g/polybag (P3), which provided an optimal balance between vegetative growth and potential generative yield.
