Abstract

Lanskap karst seperti di Gunungkidul, Yogyakarta, menghadapi tantangan serius dalam sektor pertanian akibat kelangkaan air dan kondisi tanah yang dangkal serta mudah tererosi. Keterbatasan ini menghambat produktivitas pertanian dan ketahanan terhadap variabilitas iklim. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem pertanian berkelanjutan yang secara khusus disesuaikan dengan karakteristik wilayah karst. Sistem yang dikembangkan mengintegrasikan pemanenan air hujan, ekstraksi air tanah yang terkendali, akuakultur, dan irigasi tetes. Penerapan dilakukan di Desa Sumbergiri, Gunungkidul. Air hujan dikumpulkan dari atap bangunan dan disimpan untuk digunakan saat musim kemarau, sehingga mengurangi ketergantungan pada air tanah. Air tanah diambil melalui sumur dalam dengan pompa bertenaga surya sebagai sumber cadangan. Limbah akuakultur yang kaya nutrisi dimanfaatkan untuk mengairi tanaman melalui sistem irigasi tetes yang menyalurkan air langsung ke zona akar tanaman secara efisien. Hasil penelitian menunjukkan bahwa pendekatan terintegrasi ini meningkatkan efisiensi penggunaan air, mendukung daur ulang nutrisi, dan meningkatkan hasil panen, bahkan selama musim kemarau. Sistem ini menawarkan model yang dapat direplikasi untuk pertanian berkelanjutan di wilayah karst dan daerah yang kekurangan air.

Abstract

This study investigates the potential of potato starch-based edible coatings (Amylum solani) to extend the shelf life and preserve the quality of tomatoes (Solanum lycopersicum L.) during storage. The experiment contributed to evaluating the effect of the coating on critical quality parameters, including weight loss, firmness, color stability, moisture content, vitamin C retention, and sensory characteristics. Tomatoes with edible coatings exhibited a slower rate of weight loss compared to uncoated samples, which is attributed to the coating's ability to form a protective barrier that minimizes water evaporation and respiration rates. Coated tomatoes also retained firmness more effectively, delaying the softening process caused by metabolic and enzymatic activity. The study revealed that the edible coating reduced the rate of color degradation by slowing the loss of chlorophyll and the formation of lycopene, preserving the tomatoes' visual appeal. Moreover, the coating significantly delayed the decline in vitamin C content by inhibiting oxidation and maintaining structural integrity, which was further reflected in the higher sensory scores for coated tomatoes. Organoleptic tests indicated that panelists preferred coated tomatoes due to their glossy appearance, firmer texture, and sweeter taste, although these preferences gradually decreased over time. Analysis showed that the coating extended the shelf life of tomatoes to 13.64 days, compared to 9.76 days for uncoated samples. These results highlight the efficacy of potato starch-based edible coatings as an environmentally friendly and cost-effective solution for reducing postharvest losses, meeting consumer demand for fresh produce, and improving food security. This study provides valuable insights into the practical application of edible coatings for preserving climacteric fruits such as tomatoes, with implications for sustainable agricultural practices.

Abstract

Binahong leaves are still widely used only as medicine, not yet able to reach a wider user profile. Research was conducted on the effect of drying methods and the addition of binahong leaf extract on the characteristics of biscuits. The purpose of this study was to determine the effect of three drying method variations and the addition of binahong leaf extract on biscuit characteristics, as well as to identify the drying method and concentration of binahong leaf extract that provide the highest antioxidant activity. The research design used was a Randomized Block Design (RBD) with two factors, namely drying method variations with three levels: direct sunlight, oven drying at 60°C, and indirect sunlight; and the addition of binahong leaf extract with three levels: 1%, 5%, and 10% of flour weight. The analyses carried out included physical properties (total color difference) and chemical properties (moisture content, ash content, fat content, protein content, carbohydrate by difference, and antioxidant activity). The results showed that both drying method and binahong leaf extract addition significantly affected the characteristics of biscuits. The best treatment was obtained in A2B3 (oven drying method with 10% binahong leaf extract addition), which produced the highest antioxidant activity of 60.33%. Further research is recommended on thickening or powdering the extract to reduce moisture content as low as possible so that the biscuits can meet the SNI biscuit standard 2973:2022, with a maximum moisture content of 5%.

Abstract

Organic fertilizers play a crucial role in improving soil quality and supporting sustainable agriculture in tropical regions. This study evaluates the quality of cow manure based on the solid organic fertilizer standards set by the Indonesian Ministry of Agriculture. Laboratory analyses were conducted on key chemical parameters, including organic C, C/N ratio, moisture content, macronutrients (N, P₂O₅, K₂O), and pH, accompanied by weekly composting temperature observations. The results show that the manure had a high organic C content (34.91%) and an ideal C/N ratio (17.24), indicating mature and stable compost. Moisture content (17.84%) and pH (8.17) were within the acceptable standard range, confirming good storage stability and suitability for acidic tropical soils. Nitrogen content (2.03%) met the minimum requirement, while P₂O₅ (1.26%) and K₂O (0.23%) were at moderate levels typical of cattle manure. Temperature measurements during composting showed a normal decomposition pattern, increasing from 32°C in week 1 to about 33°C in weeks 2–3 before declining in week 4, supporting the maturity of the final product. Overall, the analyzed cow manure meets the quality standards for solid organic fertilizer and has strong potential as a soil amendment and supplementary nutrient source in tropical agricultural systems.

Abstract

Background of study: Oolong tea is commonly produced from Camellia sinensis leaves, while the use of assamica variety has been rarely investigated. Differences in varietal composition and oxidation duration may influence chemical and sensory characteristics of oolong tea, particularly antioxidant performance and polyphenol content.Aims and scope of paper: This study examined how tea variety and oxidation time affect moisture content, polyphenols, antioxidant activity, and sensory properties of oolong tea. The scope included physicochemical and organoleptic evaluation to determine processing conditions that optimize functional quality.Methods: A randomized block design with two factors was applied, namely variety (sinensis and assamica) and oxidation duration (15, 25, and 60 minutes), each with four replications. Measurements included moisture, polyphenols, antioxidant activity using DPPH, and sensory evaluation of color, aroma, and taste.Result: Variety significantly affected moisture, polyphenols, and antioxidant activity, while sensory differences were observed only in color. Oxidation time significantly influenced antioxidant activity but not moisture or polyphenols. The highest antioxidant activity occurred in assamica at 15 minutes, whereas longer oxidation reduced antioxidant levels.Conclusion: The assamica variety produced higher polyphenol and antioxidant values than sinensis. Shorter oxidation preserved antioxidant activity, indicating that combining appropriate variety selection with controlled oxidation may enhance the functional attributes of oolong tea.

Abstract

Background: Biodiesel production efficiency is strongly influenced by reaction method, temperature, and reactant feeding strategy. Semi-batch transesterification offers better molar ratio control and reduced methanol waste compared to conventional batch systems. Aims: This study analyzes the effect of feed addition frequency and reaction temperature on biodiesel efficiency and characteristics using Refined Bleached Deodorized Palm Oil (RBDPO) as raw material. Methods: A Complete Block Design with two factors was applied: feed addition frequency (4×, 5×, 6× per period) and reaction temperature (40°C, 50°C, 60°C) with two replications. Biodiesel was produced using semi-batch transesterification with sodium methylate catalyst. Parameters measured included yield, density, pH, water content, glyceride profile, and methyl ester content. Data were analyzed using Duncan’s Multiple Range Test (5%). Result: The best treatment was 5× feed addition, 50°C, producing the highest methyl ester content (67.18%), yield (92.98%), density (877 kg/m³), pH 6.78, and low water content (1,401 ppm). Most quality parameters approached SNI 7182:2015 biodiesel standards. Conclusion: Semi-batch operation improves conversion control but is not yet fully optimal due to reverse reactions. Further optimization of methanol ratio and reaction time is required to suppress monoglyceride and diglyceride reformation.

Abstract

This study aims to examine the effect of varying ratios of gembili tuber flour and mocaf flour, as well as cinnamon powder concentration, on the chemical and organoleptic characteristics of cookies. The study used a two-factor Complete Block Design (CBD), namely the gembili flour to mocaf flour ratio (80 g:20 g, 60 g:40 g, 50 g:50 g) and cinnamon powder concentration (0.5%, 1%, 1.5%) with two replicates. The parameters analyzed included moisture content, ash, protein, fat, crude fiber, carbohydrates, and organoleptic tests (color, aroma, taste, and texture). The results showed that the flour ratio had a significant effect on all parameters except color, taste, and texture. Meanwhile, the addition of cinnamon powder had a significant effect on moisture content, ash, fiber, fat, carbohydrates, and color, but had no effect on protein or the organoleptic tests for aroma, taste, and texture. The best cookies were produced in treatment T2B3 (60% gembili flour : 40% mocaf with 1.5% cinnamon), yielding a moisture content of 2.69%, ash 5.21%, crude fiber 5.86%, fat 12.54%, protein 4.16%, carbohydrates 76.73%, and a panelist preference score of 5.45 (in the “agak suka” category).

Abstract

This study examines the use of empty oil palm bunch waste (EFB) as a raw material for Carboxymethyl Cellulose (CMC) for the development of biomass-based biodegradable adhesive. The novelty of this research lies in the application of EFB-derived CMC combined with tapioca starch as a biodegradable adhesive system that remains underexplored in bioadhesive development. The study used a randomized complete block design of two factors, namely the concentration of CMC (1%, 2%, and 3%) and the ratio of tapioca starch (6 g, 12 g, and 18 g). The parameters tested include viscosity, pH, adhesion, and drying time. The results showed that the concentration of CMC and tapioca starch had a significant effect on viscosity, adhesion, and sdrying time, but had no effect on pH. Increasing tapioca starch and CMC concentrations increased viscosity and adhesion through the formation of amylose–amylopectin gel network and hydrogen bond interactions with CMC, but slow down drying time due to increased water retention in the gel matrixThe best treatment was obtained in the C3P3 combination which produces the highest viscosity and adhesion values. This study confirms that EFB has the potential to be used as a raw material for CMC to produce biodegradable adhesive that is more environmentally friendly than synthetic adhesives and provides added value to palm oil industry waste.
