Abstract

Mount Ijen is a prominent region for peaberry Robusta coffee beans, which has entered international markets. Accurate real-time estimation of its chemical components is crucial for export activities. This study evaluated moisture content, lipid, and caffeine in Robusta peaberry coffee beans from Ijen using FT-NIRS (Fourier Transform – Near Infrared Spectroscopy). A total of 50 samples were scanned in triplicate, generating 150 spectral data points. The data were optimized for wavelength selection and pre-treated using Standard Normal Variate Transformation (SNV), Second Derivative (dg2), Multiplicative Scatter Correction (MSC), and normalization. Results showed that FT-NIRS proved effective for rapid and accurate estimation of these components. The best calibration model used Kubelka-Munk transformation with dg2 pre-treatment in the 1000-2500 nm wavelength range. Optimal Partial Least Squares (PLS) factors were PLS 4 for lipid content (R2 = 0.98, SEP = 0.013%, SEC = 0.012%, CV = 0.81, RPD = 2.03, consistency = 95.21%), PLS 5 for moisture content (R2 = 0.94, SEP = 0.014%, SEC = 0.014%, CV = 0.80, RPD = 4.88, consistency = 101.02%), and PLS 5 for caffeine content (R2 = 0.94, SEP = 0.014%, SEC = 0.014%, CV = 0.80, RPD = 4.88, consistency = 101.02%). Keywords: Absorbance, Caffeine, Lipid, Moisture Content, Pre-Treatment.

Abstract

The shelf life of bananas is significantly limited due to rapid deterioration during marketing. To address this issue, edible coatings made from marine and land resources can be used in food packaging, improving consumer health, sustainability, and waste reduction in the food supply chain. Despite advancements in the field, research focusing on extending the shelf life of bananas through edible coatings remains limited. This research addresses the gap in extending banana shelf life by systematically evaluating the efficacy of edible coatings in reducing spoilage and improving preservation during marketing and storage. Employing a Systematic Literature Review (SLR) and meta-analysis with the SALSA framework, 164 scholarly journals were analyzed, highlighting 11 research clusters and 40 articles specifically discussing shelf life. Among the findings, the combination of Moringa oleifera (MO) and chitosan nanoparticles (CN) emerged as a superior combination and the most effective, extending banana shelf life by up to 30 days. This combination offers notable advantages, including strong antimicrobial properties, accessibility, cost-effectiveness, and eco-friendliness, positioning it as a practical, scalable, and sustainable approach to food preservation and waste reduction. These findings highlight the potential of innovative edible coatings to reduce food waste, support sustainability, and enhance banana supply chains. Keywords: Banana, Chitosan, Edible coating, Moringa oleifera, Review.

Abstract

Garlic is widely recognized for its culinary, industrial, and medicinal applications, attributed to its sulfur compounds and allicin, which contribute to its pungent taste and distinctive aroma. This study, conducted in Sajen Village, Pacet District, Mojokerto, from January to May 2024, aimed to evaluate the effects of Phonska NPK and silica fertilizers on garlic production. A factorial experimental design with two factors was employed using a Split-Plot Design within a Randomized Complete Block Design (RCBD). The main plots were treated with silica fertilizer at concentrations of 0 g/L, 5 g/L, 10 g/L, and 15 g/L, while the subplots received Phonska NPK fertilizer at rates of 0 kg/ha (control), 400 kg/ha, 600 kg/ha, and 800 kg/ha. Data were analyzed using analysis of variance (ANOVA) and the HSD test at a 5% significance level. Results indicated that the combination of 0 g/L silica fertilizer and 800 kg/ha Phonska NPK fertilizer yielded the highest garlic production. Although the individual application of Phonska NPK fertilizer did not have a significant effect, the absence of silica fertilizer (0 g/L) significantly influenced leaf width and the development of generative structures. Keywords: Harvest, Nutrient, Potassium, Tuber size.

Abstract

Performance measurement regarding collaborative supply chain of fresh produces such as fruit and vegetables that combines vertical and horizontal collaboration structures is rarely found in the literature. Performance metrics in this lateral collaborative structure are useful for tracking and measuring the achievement of more comprehensive business goals that are not found in only vertical or horizontal structures. This research aims to explore and propose the best model for collaborative performance system (CPS) in the fresh produce supply chain (FPSC) and success factors in CPS implementation, including CPS metrics and matching collaborative individual performance (CIP) and supply chain performance (SCP). Papers from the last seventeen years including journal papers, working papers and conferences were selected in three steps. From 175 articles found in the first step, 63 articles matched the topic. In the third step, 48 articles were selected as important topics of discussion focused on the field of fresh products, with three classifications of collaboration structures and identifying CIP and SCP metrics which were then analyzed. The results of this review provide good opportunity as reference material for further research, through a comprehensive analytical description complete with a conceptual model presented to complete the gaps in this field. Keywords: Collaborative Performance System, Lateral Model, Performance Metrics, Rural Farmers, Supply Chain.

Abstract

Nitrogen (N) fertilization in coffee agroforestry system requires proper management to increase N use efficiency (NUE) and minimize N losses. This study investigated the impact of different fertilization management on N losses, N uptake, and N storage in a coffee-based agroforestry system. The study was conducted using three types of fertilizer (organic, inorganic, and mixture of organic-inorganic) with three doses (low, medium, and high), and a control treatment (no fertilization), with 3 replications. Soil leachate was collected using lysimeter at 50 cm depth (below coffee root zone) and gas emissions were collected monthly using chamber for 4 months. Soil sample at 0-20 cm depth and leaf sample were also collected. The variables included NH₄⁺ and NO₃ˉ concentration in the leachate and soil, soil N total, N uptake, N emission, N use efficiency (NUE) and partial N balance. Results showed no significant differences in N leaching or plant N uptake across treatments. However, the mixed fertilizer with high dose treatment significantly increased soil N availability while reducing N₂O emissions and improving the overall N balance. This suggests that a high dose mixed fertilizer application can enhance N utilization in coffee-based agroforestry systems, potentially improving productivity while minimizing environmental impacts. Keywords: Agroforestry, Fertilization, Nitrogen balance, Nitrogen loss, Nitrogen storage.

Abstract

Lettuce (Lactuca sativa L.) is a leaf vegetable that has a high level of consumer demand and commercial value and can be cultivated using a combination of hydroponic substrate and drip irrigation methods. This research aims to determine the effect of the time interval for providing nutrients on the growth and harvest results of three lettuce plant varieties. Plants were cultivated on cocopeat and husk charcoal media (ratio 1:3) and arranged using a Randomized Block Design (RAK) consisting of two treatments. The first treatment is the nutritional interval which consists of an interval of 2 hours with a discharge of 17 ml (I1), 3 hours with a discharge of 25 ml (I2), and 4 hours using a discharge of 34 ml (I3). The second treatment is the plant variety which consists of the Grand Rapids variety (V1), the Green Coral variety (V2), and the Red Coral variety (V3). The data is analyzed using analysis of variance and if the results obtained are significantly different then a DMRT test will be carried out. The research results showed that the Green Coral lettuce variety was better than the Grand Rapids and Red Coral varieties. This is shown by the results with the highest and best values for the observation variables of number of leaves, plant fresh weight, and chlorophyll content. The nutritional interval which consists of an interval of 2, 4, and 6 hours gave results that were inversely proportional to the variety treatment, that is, they were not significantly different in all observed variables. Keywords: lettuce plants, plant varieties, nutritional interval, substrate hydroponics

Abstract

Nagari Lawang is located in Agam Regency, West Sumatra, which is a nagari situated in the highlands with a slightly steep to very steep slope with the most types of land use in moors/fields. This can directly encourage erosion. This study aims to analyze the optimal land use pattern for reducing the rate of erosion in Nagari Lawang. The method used to calculate the erosion rate is the Universal Soil Loss Equation (USLE) and to obtain the optimal land use in reducing the erosion rate is a simulation with three scenarios. The results of the study showed that 47.29% of the Nagari Lawang land area was at an erosion rate above the tolerance erosion with the category of light to very heavy. Based on land use simulations, planning scenario III by allocating the use of shrubland into mixed gardens with planting according to contour lines and the use of shrub land into mixed forests is the best scenario because it can reduce erosion by 39.05% of the total erosion of Nagari Lawang. The reduction of erosion on the diverted land (moors/fields and shrubs) reached 45.83% of the existing condition, which was 2105.928 tons/ha/year. The best scenario land use can be used as a reference by policy makers and the community in determining appropriate land management actions in Nagari Lawang. Keywords: Erosion, Simulation, Land Use, USLE.

Abstract

Sustainable soil fertility management is crucial for global food security and addressing environmental challenges from modern agriculture. Soil health, alongside water availability, is essential for crop productivity, and soil degradation threatens food security by lowering yields and intensifying climate change. Nitrogen (N) cycling is central to soil fertility, supporting plant growth through nutrient replenishment and microbial activity. However, N is often lost through leaching, volatilization, and denitrification, reducing nitrogen use efficiency (NUE) and contributing to water pollution and greenhouse gas (GHG) emissions. Optimizing nitrogen retention in soils is vital for improving productivity and minimizing environmental harm. Biochar (BC) and humic substances (HSs) have emerged as effective strategies for improving N management. BC enhances soil fertility by increasing soil pH, cation exchange capacity, and water retention, while reducing nutrient leaching and promoting carbon sequestration. HSs, including humic acids (HA), fulvic acids (FA) and humin (HU), improve nutrient cycling by stimulating microbial activity and enhancing nutrient transport. Together, BC and HSs provide synergistic benefits for soil health, particularly in challenging environments like saline or nutrient-depleted soils. This review highlights the roles of BC and HSs in enhancing soil fertility, promoting N mineralization, and improving crop productivity. It emphasizes their potential for sustainable agricultural practices, climate change mitigation, and long-term soil health. Keywords: Biochar, Climate changes, Humic substances, Remediation, Soil fertility.
