Abstract

Rendang is a high-fat food product that is susceptible to quality deterioration during storage, particularly due to lipid oxidation and potential microbiological contamination resulting from inadequate packaging. This study investigated the effect of storage duration on the quality of beef rendang stored at room temperature, as indicated by fat deterioration, sensory changes, and microbiological quality. Beef rendang was stored for three months in vacuum-sealed aluminum foil packaging at room temperature. Monthly analyses included fat content, free fatty acid (FFA) levels, thiobarbituric acid (TBA) value, total plate count (TPC), initial spoilage assessment using the Eber test, and sensory evaluation of color, aroma, texture, taste, and overall appearance. Protein, moisture, and ash contents were determined at the beginning and end of storage to evaluate compliance with SNI 7764:2012. Protein was analyzed using the Kjeldahl method, while moisture and ash were determined gravimetrically in accordance with AOAC (2007) procedures. The results showed a gradual decline in product quality during storage. Fat content decreased from 27.00±0.16% to 20.95±0.43%, while FFA levels increased from 3.31±0.17% to 5.52±0.34%. The TBA value increased from 0.01±0.002 to 0.07±0.002 mg Ma/kg. Sensory attributes exhibited a decreasing trend over the storage period. No microbial growth, including Salmonella and Escherichia coli, was detected, and the Eber test indicated no ammonia formation. Protein, moisture, and ash contents remained within SNI limits. Overall, quality deterioration was mainly associated with lipid degradation, while the product remained safe and suitable for consumption throughout storage.

Abstract

The improvement of cucumber cultivation practices, such as proper seed selection and appropriate fertilization, has the potential to enhance seed production and quality. Therefore, this study aimed to evaluate the most effective combination of potassium and boron fertilizer doses to improve seed production and pollen viability in cucumber. A randomized block design (RCBD) with two treatment factors was used. The first factor was potassium dose, applied at three levels: 100 kg/ha, 200 kg/ha, and 300 kg/ha. The second factor was boron dose, applied at four levels: 0 kg/ha, 1 kg/ha, 2 kg/ha, and 3 kg/ha. Data were analyzed using ANOVA, with a comprehensive set of observation parameters. In conclusion, no significant interaction was observed between potassium and boron treatments across all observed parameters. The treatment of 300 kg/ha potassium had a highly significant effect on the number of seeds per fruit (342.53), the number of filled seeds per fruit (289.93), seed weight per fruit (7.13 g), filled seed weight per fruit (8.24 g), and seed production per hectare (253.64 kg). Boron fertilizer treatment at a dose of 1 kg/ha had a highly significant effect on the time to emergence of male flowers (23.44 DAP), the time to emergence of female flowers (26.33 DAP), filled seed weight per fruit (7.86 g), and seed production per hectare (241.72 kg).

Abstract

Sustainable rice cultivation requires effective nutrient management strategies to reduce chemical fertilizer dependency. Biofertilizers enriched with humic acid and microbial consortia offer an eco-friendly alternative to enhance soil fertility and plant productivity. This study evaluated the effects of biofertilizer combined with humic acid and a microbial consortium on vegetative growth, chlorophyll content, and macronutrient availability in Inpari 32 rice. The experiment was conducted in a greenhouse at Banyuwangi State Polytechnic using a completely randomized factorial design with two biofertilizer types: biofertilizer + humic acid (B1) and biofertilizer + microbial consortium (Bacillus, Trichoderma, Saccharomyces) (B2), and three application doses: 300 g, 400 g, and 500 g per pot. Although ANOVA results indicated no statistically significant differences among treatments, a consistent positive trend was observed in plant height, tiller number, and chlorophyll content at the 400 g dose. Soil N, P, and K levels tended to decrease, possibly due to enhanced nutrient uptake by plants, suggesting an improved nutrient use efficiency. Overall, the combination of biofertilizer and humic acid at the 400 g dose tended to show higher values compared to other treatments, although these differences were not statistically significant. These findings support the use of multi-species microbial biofertilizers and IoT-based precision fertilization systems to promote sustainable rice production in Indonesia.

Abstract

Coriander leaves contain bioactive compounds that are beneficial to health, but the content can differ depending on the origin and environmental conditions where they grow. Coriander leaves of local Indonesian or imported origin differ in their characteristics and bioactive compound content, necessitating analysis of both types. This study aims to analyse the bioactive compounds in the extract of local Indonesian coriander leaves from Bukittinggi, West Sumatra, and imported coriander from Egypt using gas chromatography–mass spectrometry (GC–MS). Coriander leaves were extracted using 96% ethanol in an ultrasonic bath. The extract was analysed for pH, antioxidant and antibacterial activity, residual ethanol content, and GC–MS to identify the compounds present. The results showed that the local Bukittinggi coriander leaf extract had a pH of 4.01, antioxidant activity based on DPPH inhibition of 88.34%, antibacterial activity against Staphylococcus aureus with a clear zone diameter of 23.38 mm, and a residual ethanol content of 0.68%. Meanwhile, the imported Egyptian coriander leaf extract had a pH of 3.68, antioxidant activity of 83.25%, antibacterial activity of 26.00 mm, and a residual ethanol content of 0.00%. Imported Egyptian coriander leaves exhibited higher antibacterial activity and lower residual ethanol content than local Bukittinggi coriander leaves. However, local Bukittinggi coriander leaves demonstrated greater antioxidant activity than the imported Egyptian leaves. GC–MS analysis revealed that the local Bukittinggi coriander leaf extract contained organic compounds such as 3,5-bis(1,1-dimethylethyl) phenol, phytol, and dl-α-tocopherol, unlike the imported Egyptian coriander leaf extract

Abstract

Spent hen meat has potential as an alternative raw material for traditional ready-to-eat meat products; however, its microbiological quality during storage requires evaluation. This study assessed the microbiological quality of rendang boleces (a meatball-like product) prepared from spent hen meat using Total Plate Count (TPC) analysis and Salmonella spp. detection. Samples were stored under ambient conditions (25–28°C) for 0, 2, 4, and 6 days. TPC values increased during storage, from 2.67 log CFU/g on day 0 to 4.63 log CFU/g on day 6. Samples stored for up to two days remained within the maximum permissible limit established by the Indonesian National Standard (SNI). In contrast, higher microbial counts were observed on days 4 and 6, indicating progressive microbial growth during extended storage. Salmonella spp. was not detected in any sample throughout the observation period. These findings indicate that rendang boleces maintained acceptable microbiological quality for up to two days under ambient storage conditions. The study also highlights the importance of appropriate storage and hygienic handling practices to maintain the quality of ready-to-eat meat products derived from spent hen meat while supporting the sustainable utilization of poultry resources in line with SDG 12 (Responsible Consumption and Production).

Abstract

Kale (Brassica oleracea var. acephala) cultivated in hydroponic systems commonly relies on inorganic AB Mix nutrients, which raises sustainability concerns. This study evaluated the potential of nano-technology liquid organic fertilizers (nano-POC) derived from Sargassum, Gliricidia sepium (gamal leaves) and Tithonia diversifolia as partial substitutes for AB Mix in hydroponic kale cultivation. The experiment was conducted using different substitution formulations, and plant growth responses were assessed based on morphological and biomass-related parameters. The results showed that partial substitution of AB Mix with nano-POC maintained superior growth performance compared to full organic application. The formulation P3S (50% AB Mix + 50% Sargassum nano-POC) produced the most balanced and consistent growth responses, reaching a plant height of 22.5 cm, an average of seven leaves and a dry weight of 0.17 g, and showed no significant difference from the 100% AB Mix control. In contrast, the exclusive use of nano-POC resulted in significant declines across all growth indicators. Multivariate analysis using Principal Component Analysis (PCA) confirmed the stability and consistency of the optimal treatment across growth parameters. These findings indicate that nano-POC functions effectively as a complementary nutrient source in hydroponic systems. Integrating nano-technology liquid organic fertilizers through partial substitution strategies offers a sustainable approach to reducing dependence on synthetic fertilizers while maintaining hydroponic kale productivity.
