Abstract

Melon (Cucumis melo L.) is a fruit known for its sweet and refreshing taste. Traditionally, melon cultivation has relied on conventional farming methods. The use of biofertilizers offers an alternative to reduce dependency on synthetic fertilizers. This study aimed to enhance the production of healthy, high-yielding melon plants by substituting Mutiara NPK fertilizer with Bioto Grow Gold (BGG) biofertilizer. Conducted in Sukosongo Village, Kembangbau District, Lamongan Regency, East Java, the experiment employed a factorial Completely Randomized Design (CRD).Two factors were tested: BGG fertilizer at four concentrations (0 ml/L [P0], 1 ml/L [P1], 2 ml/L [P2], and 4 ml/L [P3]) and NPK fertilizer at four doses (0 g/plant [N0], 60 g/plant [N1], 70 g/plant [N2], and 80 g/plant [N3]). Results indicated that BGG fertilizer influenced both vegetative and generative growth variables, as did the Mutiara NPK fertilizer doses. The optimal combination was achieved with a BGG concentration of 3 ml/L and an NPK dose of 70 g/plant, which significantly increased the sucrose content in melons. Keywords: Bioto Grow Gold fertilizer, Biofertilizer, Melon, NPK Mutiara fertilizer.

Abstract

Shallot is a horticultural commodity that is always needed for consumption and has high economic value. However, shallot production in East Java has decreased due to the low quality and quantity of shallot seeds. This study aims to determine the effect of concentration and frequency of paclobutrazol application on the growth and yield of shallot. This research was conducted in Sambigede Village, Sumber Pucung Subdistrict, Malang Regency in January-May 2024. The research was arranged using a Split Plot Design with 3 replication. The main plots were paclobutrazol concentrations: 50 ppm, 100 ppm, 150 ppm, and 200 ppm. The subplots were the frequency of paclobutrazol application: 1 time, 2 times, and 3 times. The combination of paclobutrazol concentration of 100 ppm and application frequency of 1 time gave the best results in inhibiting the vegetative phase, increasing tuber dry weight per clump, harvest index, and chlorophyll content. The frequency of paclobutrazol application did not significantly affect the fresh weight of tubers per clump, fresh weight of tubers per plot and dry weight of tubers per plot, but paclobutrazol concentration of 100 ppm affected the fresh weight of tubers per clump. Keywords: Bulbs, Harvest, Paclobutrazol, Shallot, Vegetative.

Abstract

Sigupai rice, Indonesia local aromatic rice varieties grown in South-West region of Aceh, is highly valued for its fragrance and quality, making it susceptible to adulteration. This study compares the performance of two portable Near-infrared (NIR) devices, SCiO and NeoSpectra, for rapid authentication of Sigupai rice. We evaluated 86 samples for qualitative analysis (i.e. authentic vs adulterated rice) and 44 samples for quantitative analysis (i.e. the level of adulteration). For the qualitative analysis using partial least squares-discriminant analysis (PLS-DA), the best estimation model could differentiate authentic and adulterated samples with an accuracy, sensitivity, specificity, and false positive rates of 89.29%, 92.86%, 85.71% and 14.29% for the NeoSpectra and 97.44%, 100%, 94.87%, and 5.13% for the SCiO, respectively at the validation stage. For quantitative analysis using partial least squares-regression (PLS-R), the best estimation model could estimate the level of adulteration with a coefficient of determination (R²), RMSEP, RPD, and consistency values of 0.92, 1.50%, 5.93 and 100.69% for the NeoSpectra and 0.96, 1.31%, 6.83 and 104.78% for the SCiO. Both portable NIR devices could be used as a rapid analysis tool for the authenticity of Sigupai rice with high accuracy. However, in this study the SCiO device showed a better performance. Keywords: Portable NIR device, Authentication, Aromatic rice, Rapid analysis, Sigupai variety.

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

The use of remote sensing technology in monitoring coffee plantations is becoming increasingly important considering the vital role of coffee in the economy as an export product that increases state revenue. However, challenges remain, especially regarding the low resolution of satellite imagery which hinders accurate and efficient monitoring of coffee fields. This study aims to improve the accuracy of coffee plantation land analysis in South OKU Regency, South Sumatra Province, by using a pan-sharpening method consisting of IHS, Brovey, and Gram-Schmidt and assisted by a composite index. Satellite image sampling data from Landsat-8 was carried out at 1800 points divided into six classes. The results of the study show that the characteristics of coffee plantation land have NDVI, EVI, and ARVI values that tend to be lower, but the NDBI and NDWI values tend to be higher than the non-coffee plantation and forest classes. This study also compares the data from the pan-sharpening method using machine learning and deep learning methods to get the best classification model. The results showed that the SVM model machine learning method on the pan-sharpening brovey data gave the best results with an ACCURACY value of 83.49 and an F1-score of 83.59 percent. Keywords: Coffee Plantations, Deep Learning, Machine Learning, Pan-sharpening, Remote Sensing.

Abstract

Efforts to increase garlic productivity can be achieved through cultivation innovations, such as selecting the appropriate tuber size and incorporating organic matter. This study aimed to determine the optimal combination of tuber size and organic matter to increase garlic yield. The research was arranged using a Split Plot Design (SPD) within a Randomized Block Design, with three replications. The main plots involved organic matter treatments: (1) no organic matter, (2) biochar (1 kg/m²), (3) biochar + manure (0.5 kg/m²:0.5 kg/m²), and (4) manure (1 kg/m²). The subplots consisted of tuber size categories: (1) small tubers (0.3-0.6 g), (2) medium tubers (0.7-1 g), and (3) large tubers (1.1-1.4 g). Results showed an interaction between large tuber sizes and the addition of manure, which produced the highest fresh bulb weight. Additionally, the combination of large tuber sizes with the addition of biochar and manure resulted in a high dry bulb weight. Keywords: Biochar, Manure, Nutrient, Production.

Abstract

Trichoderma sp. is a fungus used in oil palm plantations to control basal stem rot disease, which can reduce palm oil production by up to 80%. At PT. Bumitama Gunajaya Agro, the production of this fungus uses an autoclave, which can only produce 51 kg of Trichoderma sp. per day per unit. To meet the high demand for Trichoderma sp., a large-capacity sterilization tool called "stream" is needed for mass production. The optimal performance of the Stream shows that effective sterilization can be achieved in 20 min when the tool is operated for 45 min. The effectiveness of this sterilization time is proven by the Total Plate Count (TPC) test, which shows a bacterial count of 109×103 CFU/g and a fungal count of 35 CFU/g. The Trichoderma sp. product produced through this process has a conidium density of 8×108, 100% conidium viability, and an inhibition power of 54%, all of which exceed the standard values of SNI 8027.3:2014. Based on its production capacity, Stream can achieve production of up to 1 ton per day with quality not significantly different from Trichoderma sp. production using an autoclave. Keywords: Autoclave, Basal stem rot disease, Sterilization, TPC, Trichoderma sp.

Abstract

Surabaya is a large city with a high number of industries and population density, so there is potential for heavy metal iron (Fe) pollution which affects environmental quality and the sustainability of aquatic living creatures. Gastropods are one of the macrofauna that have difficulty moving from place to place, so their presence is a bioindicator of an area with heavy metal Iron (Fe) pollution. Gastropod sampling was carried out using the transect sampling method with sampling locations spread across three locations, namely around the Kebon Agung River, Tambak Oso River and Jagir River. The diversity index was calculated using the Shannon-Wiener diversity index. The concentration of iron (Fe) metal pollutants was analyzed using AAS (Atomic Absoption Spectrophotometer). The relationship between heavy metal Fe accumulation and gastropods was analyzed using the Pearson correlation test. The research results showed that there were 14 types of gastropods with a medium diversity index (H') with values between 1.34-2.03 and an accumulation of the heavy metal iron 35994.7-44986.3 (ppm). Keywords: Abundance, Diversity Index, Gastropods, Heavy metal iron (Fe), Surabaya East Coast River.
