Abstract

Branched-Chain Amino Acids (BCAAs), consisting of leucine, isoleucine, and valine, are essential amino acids that play important roles in protein synthesis, maintenance of muscle mass, and improvement of nutritional status. Tempeh, a traditional fermented soybean product, is a potential source of BCAAs, protein, isoflavones, and other bioactive compounds. However, the relatively short shelf life of fresh tempeh necessitates processing innovations to produce food products that are more practical and have longer storage stability. This study aimed to develop cookies formulated from tempeh flour and purple sweet potato as a functional food rich in BCAAs and antioxidants. The developed product is expected to serve as a nutritious snack alternative that supports nutritional requirements and contributes to improved quality of life, particularly among individuals with increased protein and antioxidant needs. The study also evaluated the physical, chemical, and sensory characteristics of the formulated cookies. A Completely Randomized Design (CRD) with three formulations was employed. The moisture contents of Formula 1 (F1), Formula 2 (F2), and Formula 3 (F3) were 11.58%, 8.93%, and 9.18%, respectively. Color analysis showed variations in L*, a*, and b* values among formulations, while sensory evaluation revealed no significant differences in consumer acceptance between formulations. Extended baking time is recommended to further reduce moisture content and improve product quality and shelf-life stability.

Abstract

This study evaluates rainfall deficit anomalies during the main rice planting season to detect hidden meteorological droughts. It analyzes satellite-derived precipitation variables using the 1-month Standardized Precipitation Index (SPI-1). The observation timeline spans 2014 to 2024 across Indramayu Regency, utilizing CHIRPS spatial data. The results revealed that extreme drought anomalies surprisingly occurred during the peak wet seasons, specifically in December 2023 (SPI -2.48) and February 2024 (SPI -1.81). These anomalous wet-season precipitation failures severely disrupted the critical early vegetative phases of rice. The findings imply an urgent need for agricultural stakeholders to transition from static to dynamic planting calendars integrated with probability-based climate prediction models to mitigate mass crop failures.

Abstract

This study examined the ecological condition of aquatic vegetation in Pananualeng Beach, Sangihe Islands Regency, North Sulawesi, focusing on seagrass species composition, community dominance, and supporting water quality as key ecological indicators. Field observations were conducted in October 2025 at three purposively selected sampling stations using line-transect quadrats for seagrass assessment and in-situ measurement of temperature, salinity, dissolved oxygen, pH, and nutrients. The results showed that Thalassia hemprichii dominated the seagrass community, followed by Enhalus acoroides, indicating suitable habitat conditions and relatively stable aquatic vegetation. Water quality values were within acceptable seawater quality ranges, with no detected nitrate, nitrite, or ammonia. These findings indicate low anthropogenic pressure and support sustainable tourism management and seagrass conservation.

Abstract

The rapid harvest cycle of pakcoy and its high nutritional value have increased its cultivation intensity in Indonesia, followed by rising production needs. This experiment evaluated the response of pakcoy (Brassica rapa L.) growth and yield to the combined application of goat urine liquid organic fertilizer and NPK Mutiara fertilizer. The study was carried out in Kutagaluh Village, Tiganderket District, Karo Regency, North Sumatra. A factorial randomized block design with three replications was applied. Goat urine fertilizer treatments consisted of U0 (0 ml/L), U1 (75 ml/L), U2 (150 ml/L), and U3 (225 ml/L), while NPK Mutiara fertilizer treatments included N0 (0 g), N1 (5 g), N2 (10 g), and N3 (15 g). Observations indicated that both single and combined treatments significantly improved the growth and production performance of pakcoy.

Abstract

This study aims to analyze the physical characteristics of organic mulch sheets made from banana stalks, water hyacinth, and a combination of both, as well as to evaluate their effectiveness on soil microclimate, weed growth, and the yield of Chinese cabbage (caisim) in the highlands of Karo Regency. The study employed an experimental design using a non-factorial Randomized Block Design (RBD) with four treatments and three replications. The observed variables included the physical properties of the mulch, the degree of degradation, soil coverage effectiveness, weed growth, and crop yield during the study’s observation period. Data were analyzed using an F-test at the 5% significance level and the BNJ test. The results showed that the organic mulch mixture of banana stalks and water hyacinth (1:1) had the best physical characteristics, with a tensile strength of 0.9761 MPa, elongation of 1.47%, and Young’s modulus of 15.7532 MPa, as well as the lowest damage rate (45%) and the highest soil coverage effectiveness (80%). The use of organic mulch had a significant effect on suppressing weed growth compared to no mulch. The mixed mulch produced the lowest number of weeds, at 28.33 individuals, and the lowest weed weight, at 6.33 g. However, differences in mulch type did not have a significant effect on the weight of the Chinese cabbage plants. Overall, a mulch mixture of banana leaves and water hyacinth is recommended as the most effective organic mulch alternative for weed control in Chinese cabbage cultivation.

Abstract

Dragon fruit skin contains betacyanin, a pigment responsible for the red color. Red dragon fruit skin can be used as a flour ingredient in artificial feed containing carotenoids, which is useful for enhancing the color of ornamental fish. The aim of this research is to determine the effect of using red dragon fruit peel flour concentration in feed on improving the color of koi betta fish. The research implementation period was 55 days from October 6 to November 27, 2025, including 1 week pre-research, 3 days without test feed and 45 days of research. The test fish used in the study were 12 koi betta fish, with four treatments and three replications. The test material used was red dragon fruit peel powder added to the betta feed. The addition of red dragon fruit peel flour in feed for koi betta fish shows an increase in the brightness of different colors, this is due to the different doses given in the feed. The highest color enhancement was achieved at doses of 20% and 30%. Adding red dragon fruit peel powder to the feed is well absorbed by the fish, resulting in an increase in the brightness of the koi betta's color. The survival rate of koi betta fish for 45 days for all treatments was 100%.

Abstract

This research investigated how replacing wheat flour with quinoa flour influenced the sensory acceptance, protein concentration, and moisture level of odading. The experiment applied a single-factor completely randomized design consisting of four formulations. The formulations were F1 without quinoa flour, F2 with 10% quinoa flour, F3 with 20% quinoa flour, and F4 with 30% quinoa flour. Sensory evaluation was performed through a hedonic test involving 40 untrained panelists. Each panelist assessed the appearance, aroma, flavor, and texture of the products using a nine-point preference scale. Differences in sensory scores among the formulations were examined using the Kruskal–Wallis test. When significant differences were identified, further comparisons were conducted using the Mann–Whitney test at a significance level of p<0.05. Laboratory measurements of protein and moisture were performed at the SIG Laboratory in Semarang. The findings indicated that the proportion of quinoa flour significantly influenced product appearance (p<0.001) and aroma (p=0.005). In contrast, no statistically significant differences were found in flavor (p=0.620) or texture (p=0.368). A gradual increase in protein was observed as more quinoa flour was incorporated. Protein content rose from 7.90% in the control formulation to 9.20% in the formulation containing 30% quinoa flour. The moisture values varied between 23.13% and 30.42%, with F2 showing the highest moisture content. These findings demonstrate that incorporating quinoa flour at levels of up to 30% can improve the protein content of odading while maintaining consumer acceptance of its flavor and texture. Nevertheless, higher quinoa flour proportions may produce noticeable changes in appearance and aroma.

Abstract

The broiler chicken farming business plays a vital role in Indonesia’s livestock sector but is exposed to high risks, particularly production, price, and financial risks. This study aims to analyze the types and levels of business risks and to examine risk mitigation strategies in broiler chicken farming businesses operating under a partnership system. This study employs a case study approach focused on the Risky Astiani Broiler Chicken Farm, located in Jawi-Jawi Village, Bulukumpa Subdistrict, Bulukumba Regency. Data were collected from four informants (one owner and three workers) using purposive sampling. The probability and impact of risks were measured using a Likert scale, then analyzed using the Severity Index (SI) and Risk Score (SR = P × D), and mapped onto a probability–impact matrix. The results indicate three main risks: production risk, price risk, and financial risk. Price risk falls into the high category, while production risk and financial risk fall into the moderate category. Risk mitigation efforts were implemented through enhanced daily monitoring, improved management of closed-house systems, intensified coordination with partner companies, and better financial planning. Although partnerships can reduce uncertainty regarding inputs and marketing, farmers’ weak bargaining position in price setting remains a major vulnerability affecting business sustainability.
