In line with this national rice productivity improvement strategy, the Situbondo Regency Government in East Java Province is actively participating in initiating the development of new superior rice varieties. In early 2023, Situbondo Regency released a new superior rice variety, the Bk Situbondo 01 Agritan Variety. This new rice variety was developed for the IP 400 program. In 2024, the cultivation of this superior rice variety, Bk Situbondo 01 Agritan, began in several villages, one of which was in Battal Village, Panji District, primarily by the Joyo Mulyo 3 Farmers Group. In this regard, it is deemed necessary to conduct research to determine the income and financial efficiency of the superior rice variety Bk Situbondo 01 Agritan. The results of the study indicate that financially the income is recorded as profitable and the farming is efficient. Financially, if it is calculated that there is a decrease in the amount of production and a decrease in production prices of up to 15%, as well as an increase in variable costs of up to 15%, assuming that other factors are considered constant, the new superior rice variety farming business Bk Situbondo 01 Agritan, recorded that the income is still profitable and the farming business is still efficient. It can also be seen that the factors: (a) decrease in the amount (quantity) of production, and (b) decrease in production prices, are relatively more sensitive in responding to the decrease in the level of income and efficiency of the farming business, when compared to the factor: (c) increase in variable costs of the farming business.

This study aims to design a blanking die used for mass-producing mobile phone holders while prioritizing efficiency and dimensional accuracy. The die set developed includes key components such as the punch, die, stripper, guide post, and fastening bolts. The product produced has dimensions of 138 × 63 × 2 mm and uses ST 37 steel as the raw material. Based on calculations, the required blanking force is 129,000 kN, which is considered safe for the production process. The design also accounts for an optimal clearance of 0.083 mm and a die thickness of 35 mm to effectively withstand the working load. Simulations using stress analysis methods reveal that the von Mises stress distribution on both the punch and die remains below the elastic limit of SKD11 material. The maximum stress on the punch is recorded at 2.437 × 10⁵ N/m², while on the die it reaches 5.153 × 10⁵ N/m², both well below the yield strength of SKD11, which is 2.918 × 10⁸ N/m², indicating that these components operate safely without the risk of plastic deformation. To strengthen the construction, the stripper is designed with a thickness of 12 mm, and the addition of four SCM435 bolts is recommended to improve system stability. This die design is verified through manual calculations and Finite Element Analysis (FEA) to ensure its reliability. Overall, the findings of this study demonstrate that the designed blanking die can support mass production with high precision, optimal structural strength, and long-term durability.

The use of technology in rice farming can significantly increase production, reduce management time, expand cultivated land, and improve product quality to meet consumer standards. When rice production meets market demand, the selling price becomes higher, thus increasing farmers’ income and welfare.

Waste candlenut shells are one type of biomass that has significant potential to be developed as an alternative energy source, particularly in the form of briquettes. Candlenut shells, which are typically discarded as agricultural waste, contain combustible material that can be transformed into solid fuel. However, the traditional briquette molding process is still done manually, which is time-consuming, inefficient, and often results in inconsistent briquette shapes and density. This study aims to design and develop a briquette molding machine specifically for processing candlenut shell waste, with the goal of improving both production efficiency and the quality of the briquettes produced. The research methodology includes several stages: mechanical design, selection of appropriate materials, fabrication of machine components, assembly, and performance testing of the machine. The resulting machine utilizes a screw conveyor compression system powered by a 5.5 HP petrol engine. It features a cylindrical mold with a 40 mm diameter to shape the briquettes uniformly. During the performance test, the machine demonstrated a maximum production capacity of 14.3 kg per hour, with an average processing time of 24 minutes and a briquette yield reaching up to 85%. The findings indicate that the machine can significantly streamline the briquette production process while maintaining product consistency and quality. This briquette molding machine is particularly suitable for household and small-scale industries aiming to utilize renewable energy sources and reduce dependency on fossil fuels. The use of this machine also supports environmental sustainability by converting agricultural waste into a usable energy product.  

Background: Traditional naval maintenance strategies rely on centralized supply chains and pre-manufactured spare parts, leading to long repair downtimes and logistical inefficiencies, particularly for vessels operating in remote maritime regions. Additive manufacturing (3D printing) offers a disruptive alternative by enabling on-demand production of spare parts, reducing dependence on external suppliers, and enhancing fleet self-sufficiency. However, material durability, operational feasibility, and cost-effectiveness remain underexplored for naval applications. Original Value: This research advances the study of AM in naval engineering, assessing its practical viability beyond theoretical potential. Unlike previous studies focusing on commercial maritime applications, this study evaluates 3D printing’s impact on naval fleet readiness, supply chain resilience, and sustainability. Objectives: The study investigates how 3D printing can optimize naval maintenance efficiency, specifically analyzing its feasibility, material performance, cost implications, and logistical advantages. Methodology: A qualitative-empirical approach was used, combining material performance testing, expert interviews, and operational case studies to evaluate mechanical durability, economic feasibility, and AM integration challenges. Results: Findings indicate that AM reduces repair downtime by 40%, lowers part procurement costs by 30–50%, and enhances supply chain resilience. However, material limitations and infrastructure readiness remain key adoption challenges. Conclusions: Hybrid AM adoption—where 3D printing supplements rather than replaces traditional manufacturing—offers the most practical near-term approach for naval fleets. Strategic investment in material research, onboard AM training, and fabrication infrastructure will enhance fleet efficiency, reduce environmental impact, and future-proof maritime maintenance strategies.

This study was conducted to examine the effectiveness of Kevlar as a structural material in Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicles (UAVs), particularly those designed with winglet innovations. In UAV development, material selection plays a crucial role since it directly affects flight performance, fuel efficiency, and the overall durability of the aircraft structure. Kevlar is widely recognized as a lightweight yet highly durable material, making it an interesting candidate to replace more conventional options such as aluminum and carbon fiber composites. Two approaches were applied in this research: numerical simulations using aerodynamic software and experimental testing on a prototype wing and winglet reinforced with Kevlar. The analysis focused on comparing lift, drag, total aircraft weight, and fuel consumption between Kevlar-based structures and conventional materials. The results demonstrate that Kevlar significantly improves aerodynamic efficiency and extends flight endurance due to its lower weight. Moreover, Kevlar exhibits superior resistance to dynamic loads and impacts, which are critical during certain flight conditions. However, challenges remain in terms of higher production costs and more complex manufacturing processes compared to traditional materials. Despite these limitations, the findings provide valuable insights for developing more efficient and durable MALE UAVs, while also encouraging innovation in aerodynamic design through the application of winglet technology.

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 study aims to analyze the effect of fishing ground differences between WPPNRI 711 and 712 on squid (Loligo spp) catches using boat-operated falling nets landed at Nusantara Fishing Port Muara Angke, Jakarta. The research employed a quantitative approach with a two-treatment experimental design, involving fishing operations in two different areas with an equal number of trips (six trips each), analyzed using an independent samples t-test. The results indicated no statistically significant difference in catches between WPPNRI 711 and 712 (p = 0.747 > 0.05). However, production data revealed variations in catch differences, with CPUE (Catch Per Unit Effort) in WPP 711 being higher than in WPP 712. These variations are likely influenced by environmental factors, oceanographic conditions, fishing pressure, and squid spawning seasons. The implications of this study highlight that differences in fishing grounds do not always produce significant statistical impacts on catches but remain crucial for sustainable squid fisheries management. Policy recommendations include regulating fishing efforts based on spawning seasons, routine stock monitoring through CPUE, and adopting advanced fishing technologies to enhance efficiency and sustainability. This research provides valuable input for fisheries management and supports sustainable utilization of squid resources at Muara Angke.

The research project is titled Production Potential of Bitter Melons (Momordica charantia L.) Using POC Azolla and AB Mix on the Deep Flow Technique (DFT) System was carried out in Bungin, North Makale District, Tana Toraja Regency from May to August 2025. This study aims to determine the economic potential of bitter melon plants by providing AB Mix and POC Azolla nutrients in hydroponic methods and analyze the best influence of these nutrient combinations on the growth and production of bitter melon plants. The research method used was a Group Random Design (RAK) with four treatments, namely 100% AB Mix, AB Mix 80% + POC Azolla 20%, AB Mix 70% + POC Azolla 30%, and AB Mix 60% + POC Azolla 40%. The results of the study showed that P1 treatment (AB Mix 80% + POC Azolla 20%) had the best influence on the vegetative and generative growth of bitter melon plants. This treatment results in a higher average plant height, leaf count, and fruit weight than other treatments. This proves that the combination of Azolla liquid organic fertilizer (POC) with AB Mix is able to provide a balance of nutrients that support photosynthesis, tissue formation, and fruit quality. In addition, the application of the DFT hydroponic system has been proven to increase the efficiency of water and fertilizer use, reduce the risk of soil pest attacks, and produce more hygienic bitter melon products. These findings show that hydroponic cultivation innovation with the use of POC Azolla can be a sustainable solution in supporting food security while being environmentally friendly. Thus, this research makes an important contribution to the development of modern agricultural technology, especially in optimizing the production of vegetables with high economic value.

This study aims to analyze the thermal performance of the heating system in a small-scale plastic bolt molding machine using LDPE material, in order to determine process parameters that are efficient while maintaining product quality. The method used includes experimental testing at two set-point temperatures (90 °C and 120 °C), measurement of melting time and feed mass per cycle, as well as heat balance calculations separating the contributions of conduction, convection, and radiation on the barrel heated by a band heater. In addition, the power/energy requirement per cycle and productivity projections based on hopper capacity were calculated. The results show that increasing the set-point from 90 °C to 120 °C accelerates melting from ±240 s to ±180 s (≈25% faster). Heat transfer analysis confirmed the dominance of conduction (≈329.7 W at 90 °C and ≈471 W at 120 °C), while convection and radiation contributions were much smaller; the total system heat rate was ≈342.7 W (90 °C) and ≈490.8 W (120 °C). The discussion highlights the process trade-off: higher set-points increase production rate and mold filling quality (due to lower melt viscosity), but may raise energy consumption per cycle and require tighter mold temperature control to limit shrinkage/warpage. The practical implications for SMEs are the need for efficiency strategies based on barrel insulation, heater contact area optimization, and correlation of temperature-time settings with quality and energy consumption targets. This study concludes that controlled temperature and heating duration, supported by simple yet targeted thermal design, can improve cycle time consistency, dimensional precision, and energy efficiency in small-scale plastic bolt molding machines.

The purpose of this study was to gain a better understanding of how the operational budget planning process is applied to the Mebel Serba Usaha (Mebel Serba Usaha) business, which falls into the micro, small, and medium-sized business category. A quantitative descriptive approach was used, collecting data through direct interviews and observing business activities. The obtained data was then examined to determine costs. Furthermore, sales records over the past four years were evaluated for their use. The analysis revealed that Mebel Serba Usaha has never created an operational budget. This situation makes it difficult for the company to manage its finances, which ultimately impacts performance and profitability. The study shows that an operational budget is a crucial tool for more targeted financial management. Operational budget planning helps companies develop long-term business plans and organize and monitor expenses. The results of this study also emphasize that the absence of a budget tends to make companies lack a clear reference point for determining sales targets and controlling production costs. With structured budget planning, companies can more easily identify spending priorities, estimate cash flow, and assess the efficiency of resource use. Furthermore, implementing an operational budget can improve managerial discipline because every financial decision is based on careful planning, not just on immediate needs. Another benefit is increased transparency in fund management, thereby minimizing the risk of waste or misallocation of costs. Therefore, this study provides a practical contribution in the form of recommendations on the importance of implementing an operational budget for micro, small, and medium enterprises, particularly in maintaining sustainability and increasing competitiveness amidst increasingly fierce business competition.This research is expected to be a reference for other MSMEs in developing a more effective and sustainable financial system.

Oil palm plantations play a vital role in Indonesia’s economy; however, the dominance of monoculture practices has led to environmental and social issues such as land degradation and unstable farmer incomes during the replanting period until the first harvest (TM1). To address these challenges, the oil palm–pineapple intercropping system has been developed as an alternative strategy to improve land-use efficiency, income diversification, and farming sustainability. This study aims to: (1) analyze the influence of land size, farmer age, farming experience, and rainfall on the productivity of the intercropping system; (2) develop sustainable landscape management strategies using SWOT and SWOT matrix analysis; and (3) provide data-driven policy recommendations to support sustainable oil palm plantations. The research methods include multiple linear regression analysis for socio-economic variables, correlation analysis for environmental factors (rainfall), and SWOT analysis to evaluate Strengths, Weaknesses, Opportunities, and Threats  of the intercropping system. The results indicate that land size has a significant positive effect on production, while farming experience shows a significant negative effect. Rainfall has a strong positive correlation with yields, and SWOT analysis positions the intercropping system in a progressive quadrant with promising Opportunities for development. In conclusion, the oil palm–pineapple intercropping system has the potential to enhance productivity, stabilize farmer incomes, and support environmental sustainability. Therefore, diversification-based management strategies and supportive policies are essential to Strengthen the welfare of local communities.
