Melakukan evaluasi pengaruh pupuk kandang ayam dan NPKMg terhadap produktivitas tanaman aren. Sugar palm (Arenga pinnata Merr.) is a plantation commodity that is very beneficial ecologically and financially because it can adapt to various geographical conditions such as mountains, valleys, riverbanks, and undulating land. However, the development of this plant is still constrained by low cultivation intensification, unstructured planting patterns, and optimal land use, resulting in low productivity. Increasing the productivity of sugar palm plants can be achieved through intensive cultivation. The purpose of this study was to study how chicken manure and NPKMg fertilizer affect the growth of sugar palm plants and determine the best fertilizer dosage.

Abstract

Leaf area is an important parameter in plant physiology studies because it is directly related to photosynthetic activity and plant productivity. However, conventional methods for measuring leaf area still face limitations in terms of cost, equipment, and efficiency. This study aimed to analyze the leaf constant values of starfruit and sapodilla plants based on digital image processing as a foundation for applying the Montgomery method. A total of 40 leaf samples from each species were analyzed using digital imagery via ImageJ software to obtain the measured leaf area, which was then compared to the predicted leaf area using the Montgomery equation. The resulting leaf constants were 0.520 for starfruit and 0.642 for sapodilla, with a stable and consistent value distribution. Prediction accuracy evaluation using R², RMSE, NRMSE, NSE, and Willmott’s index showed low error rates and very high model efficiency. These findings suggest that the obtained leaf constants are reliable for rapid and non-destructive estimation of leaf area. This method has the potential for broader application in supporting precision agriculture and efficient monitoring of tropical plant growth.

Abstract

Wood apple (Feronia limonia (L.) Swingle) plants are currently classified as rare and endangered, so they require the development of new plant populations. Wood apple plants only bear fruit once a year, with seed harvest time ranging from 8-9 months after anthesis; therefore, seeds are not available throughout the year. To ensure the availability of wood apple seeds, it is necessary to store them, but stored seeds generally decrease in viability due to chemical changes that occur within the seeds. The study aimed to determine the effect of polyethylene glycol (PEG) concentration and storage time on the viability of wood apple seeds. The study was a factorial experiment consisting of two factors using a complete random design that was repeated three times. The first factor is the concentration of PEG, which consists of four levels: 0%, 20%, 40%, and 60%. The second factor is that the storage length consists of three levels, namely 0, 12, and 18 months. The data from the study were analyzed and further tested using Duncan's Multiple Range Test at a 5% significance level. The results showed that the concentration of polyethylene glycol had an effect on the percentage and rate of germination of wood apple seeds, but had no effect on the growth of germination. The storage time does not affect the percentage and rate of germination, but it does affect the growth of germination. Wood apple seeds stored for longer than 12 months exhibit declining sprout growth.

Abstract

Consistent product quality is crucial for maintaining competitiveness in the competitive bakpia (bakpia) industry. This study aims to analyze defect rates, identify dominant defect types, and evaluate the stability of the production process at the Bakpia Jogkem, Alun-alun Kidul, Yogyakarta, Micro, Small, and Medium Enterprises (MSMEs), as a case study. This study used a quantitative approach through Statistical Quality Control (SQC) tools, including a Pareto Diagram for problem prioritization and a Control Chart (P-Chart) for stability analysis. The analysis concluded that the production process operates at a 1% defect rate and is in statistical control. The Pareto Diagram identified two major defects classified as the vital few: "Scorched" (50% of total defects) and "Hard Skin" (20%). Although the process is stable and capable, this study recommends continuous improvement efforts focused on the root causes of these two dominant defects to improve quality performance to a more optimal level.

Abstract

Types of tractors used for tillage operations in paddy fields have developed in varius types with diffrent performances.  The purpose of this study is to analysis the costs, yields, profit, and efficiency of rice farming and compare them with farms that employ four-wheel tractors, rotary tillers, and moldboard flows.  A survey-based study was carried out in the Rengat Barat District of the Indragiri Hulu Regency from October 2022 to March 2023.  A  total of 70 farmers was chosen at random for samples; 20 of them used four-wheel traktor, 25 used rotary tillers, and 25 used moldboard flows. Data were obtained from primary and secondary data. The primary data were collected by personal interviews. The collected data were tabulated and then analized using simple matematic and different test.  The results showed that the rice farming using four-wheel tractors was the best performnce in costs (IDR 7,198,530/ha/growing season)) and economic efficiency (1.69). The best performance in productivity (2.8 ton/ha/growing season)) and profit (IDR. 5,443,486/ha/growing season)) was found for the rice farmings used mouldboard flows. Based on difference test showed that the average of production costs, productivity, profit and eficiency significanly differed between rice farming used four-wheel tractors, power tillers and moulboard plows at the significant level of 5%. The findngs suggest that farmers must choose the best performnace of rice farming by using four-wheel tractors for a higher eficiency or mouldboard flows for getting more profit.

Abstract

This study's objective is to analyze the factors influencing the income of cayenne pepper farming in Rasau Jaya Tiga Village, Rasau Jaya District, Kubu Raya Regency. The background highlights the importance of the horticultural sector, particularly cayenne pepper, which has high economic value but is vulnerable to significant price fluctuations, thereby affecting farmers’ income. The research employed a quantitative descriptive method with a census approach, involving 52 farmers as respondents. Questionnaires, interviews, and observations were used to gather primary data, while relevant institutions provided secondary data. Data analysis was conducted using the Cobb-Douglas Unit Output Price (UOP) function. The results showed that 74.50% of income variation was influenced by seed price, lime price, organic fertilizer price, NPK fertilizer price, fungicide price, insecticide price, and labor wages. Simultaneously, all variables had a positive and significant effect on income; however, partially, only lime price, NPK fertilizer price, and labor wages had significant effects. NPK fertilizer had a positive effect, while lime price and labor wages negatively affected income. In contrast, seed price, organic fertilizer price, fungicide price, and insecticide price had no significant effect. The study concludes that optimizing the use of NPK fertilizer and managing lime and labor costs are crucial to improving farmers’ income.

Abstract

This research was conducted on C-type overflow peatland in Rasau Jaya Dua Village over a period of approximately eight months, from the preparation phase to data analysis. The objective of this study was to evaluate the growth and yield performance of several acid-tolerant maize genotypes and to identify those with potential to be released as new superior varieties. The experiment was arranged in a Randomized Block Design (RBD) with five treatments and five replications. The treatments consisted of five maize genotypes developed through breeding programs: A = F15-1-Bm-2-2; B = F15-1-Cm-2-2; C = F15-1-Dm-2-2; D = F15-1-Em-2-2; and E = F15-1-Fm-2-2. Observed variables included key agronomic traits such as plant height, ear height, days to tasseling and silking, number of rows per ear, ear circumference, ear diameter, number of kernels per row and per ear, ear weight with husks, grain weight per ear, 1000-kernel weight at 14% moisture content, and grain yield per plot. Data were analyzed using analysis of variance (ANOVA). The results showed that genotype D (F15-1-Em-2-2) exhibited the greatest plant height, with an average of 215.94 cm, while genotype C (F15-1-Dm-2-2) had the shortest, at 188.24 cm. The highest yield was achieved by genotype E (F15-1-Fm-2-2), reaching 5.15 tons/ha, whereas genotype C recorded the lowest yield at 3.49 tons/ha. Several genotypes demonstrated promising performance and potential for further development as superior varieties for cultivation on acidic peatland.

Abstract

Due to land conversion, there is less land available for rice, a product that is crucial to the country's food security. Rice productivity is declining as a result of this situation, particularly in Pajintan Village, East Singkawang District, Singkawang City, where most farmers manage small plots of land for meager pay. Using a survey method on 76 farmers who were specifically chosen and analyzed using multiple linear regression using SPSS version 25, this study aims to investigate the impact of land area, urea fertilizer seeds, phonska fertilizers, pesticides, and labor on rice production. It found that the majority of respondents were women between the ages of 46 and 55 who were classified as productive age, had only completed elementary school (53.95%), had only 1–10 years of farming experience, and managed, and managing narrow land <0.5 ha. The study using multiple linear regression illustrates that the seed variable has a positive and significant impact on lowland rice production, while land area, urea fertilizer, and labor have a negative and significant impact on lowland rice production. Based on the evaluation of the adjusted R2 of 0.380, it shows that the model is only able to explain 38% of the production variation, while the rest is influenced by other factors outside the model, such as irrigation conditions, weather, and limitations in farm management. This finding indicates the importance of managing production factors, especially the use of quality seeds, the use of appropriate fertilizers, and labor efficiency in increasing lowland rice production.

Abstract

Food security has long been a political discourse in Indonesia, often presented through statistical claims of production surplus and reduced import dependency. However, empirical realities at the household level demonstrate persistent challenges related to equitable distribution, nutritional adequacy, environmental degradation, and farmer welfare. Through a qualitative literature review approach, this article critically examines government reports, academic publications, and field-based findings to deconstruct the multidimensional aspects of food security in Indonesia. The findings indicate that food security is frequently narrowed to rice production, overlooking local food diversity and systemic vulnerabilities exacerbated by climate change, land conversion, and the aging farmer population. Moreover, heavy reliance on imported commodities exposes the nation to global market fluctuations. True food security should transcend production-centric approaches and integrate fair access, nutritional adequacy, ecological sustainability, and smallholder farmer empowerment. This article emphasizes the need for a paradigm shift in food policy towards inclusive, resilient, and locally rooted food systems.

Abstract

Chrysanthemum (Chrysanthemum spp.) is an important floricultural commodity in Indonesia. However, its production is seriously threatened by white rust caused by Puccinia horiana. Conventional control still depends on synthetic fungicides, which pose risks of pathogen resistance and environmental contamination. The use of biological control agents (BCAs) offers an environmentally friendly and sustainable alternative within the framework of Integrated Pest Management (IPM). This review summarizes current studies on the use of Pseudomonas fluorescens, Bacillus subtilis, Trichoderma spp., and Cladosporium spp. for managing white rust in chrysanthemum. The main mechanisms include antibiosis, parasitism, competition for space and nutrients, and induced systemic resistance (ISR). Research shows that BCAs can suppress P. horiana infection and improve plant growth, although their effectiveness varies depending on environmental conditions, formulation stability, and farmer adoption. Future research should focus on locally adapted isolates, improved formulation technology, and multilocation trials to ensure field consistency. Policy support and farmer participation are also essential to expand the use of BCAs and promote sustainable chrysanthemum production.

Abstract

National food reserves are built through the roles of the central government, local governments, and communities, one of which is implemented through the development of Community Food Barns (Lumbung Pangan Masyarakat/LPM) as an effort to empower communities and strengthen food-related institutions. This study aims to analyze the business feasibility of LPM from both financial and non-financial aspects, as well as to formulate development strategies to support food security. The research method employed is a case study using a descriptive exploratory approach with qualitative and quantitative analyses. Financial analysis uses indicators such as Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period, and Return on Investment (ROI), while non-financial analysis covers legal, organizational, marketing, and socio-economic aspects. The results show that LPM Ngudi Tani is financially feasible, with an NPV of IDR 476,072,831, an IRR of 52%, a payback period of one year, and an ROI of 36%. From a non-financial perspective, LPM has legal status, a clear organizational structure, an established marketing system, and contributes to stabilizing the supply and prices of rice and unhusked rice, as well as creating employment opportunities. The SWOT analysis places LPM in a growth and development position. The main recommended strategy is strengthening partnerships to increase sales, supported by policy measures, resource optimization, and capacity building of human resources.
