Abstract

Smoked milkfish is a processed fish, a signature item of Sidoarjo Regency. Smoked milkfish has different criteria depending on the production process. Sensory attributes are among the most important consumer preferences. This study aimed to examine the sensory attributes of smoked milkfish and determine the dominant sensory attributes that influence consumer preferences. The Rate-All-That Apply (RATA) method was used to determine the tested food products. Five samples of smoked milkfish were tested with 70 respondents residing in Surabaya and Sidoarjo. There are 13 significantly different sensory attributes, including aroma (smoky, sweet), taste (savory, sour, sweet, salty, spicy), color (brown, golden yellow, reddish), and texture (dry, fibrous, wet). The distinguishing parameters of the five samples are their unique characteristics. The results of Principal Component Analysis (PCA) showed that samples 134 and 534 had dominant attributes of sweet taste, salty taste, spicy taste, brown color, sweet aroma, and smokiness. Sample 315 had a fibrous texture and sour taste. Sample 231 had a dominant wet texture and yellow color. Sample 405 had a dominant dry texture, savory taste, and reddish color. The preference mapping showed that the most preferred sample was 134.

Abstract

This study aimed to investigate the impact of various substrates and nutrients on the growth and yield of Brazilian spinach (Alternanthera sissoo) in a floating raft hydroponic system. The research was used a factorial Completely Randomized Design (CRD) with two factors: substrate type (M) consisting of rice husk charcoal, sphagnum moss, and compost; and nutrient type (A) comprising AB Mix, NPK, and Gandasil D. There were 9 treatment combinations, each replicated 3 times, resulting in a total of 81 plant samples. The observed parameters included time to sprouting, plant height, number of leaves, number of branches, canopy diameter, fresh weight, and dry weight of the plant. The results showed a significant interaction between substrate and nutrient types on the number of branches at 6 weeks after planting, while no interaction was observed for other parameters and the best results were obtained from the combination of rice husk charcoal substrate and AB Mix nutrient. Substrate and nutrient types significantly affected plant growth (height, number of branches, and canopy diameter) and yield (fresh and dry plant weight as well as fresh and dry root weight). Rice husk charcoal and AB Mix nutrient produced the best plant growth and yield up to 6 weeks after planting.

Abstract

Panambangan Village has been designated as a tourist village in Cirebon Regency; however, its potential has not been optimally managed due to a lack of comprehensive planning. The purpose of this study is to analyze the potential of Panambangan Village and formulate recommendations for its development concept as a community-based tourism village. The research method employed is a descriptive qualitative approach, with a special emphasis on participatory mapping, which was implemented through focus group discussions (FGDs). This research process consists of three main stages: potential inventory, analysis, and formulation of recommendations. The results showed that Panambangan Village has significant potential, including natural attractions such as mountain views, rice fields, and rivers, supported by good environmental quality, as well as cultural potential. Basic infrastructure is adequate for supporting tourism, and the other side infrastructure, such as transportation and accommodation access, still requires improvement. The culmination of this research, through participatory mapping activities, successfully mapped the village's potential points, which were then grouped into three recommended development zones: the revitalization zone, the settlement zone, and the cultural zone.

Abstract

Red galangal (Alpinia officinarum) is an Indonesian native herb rich in bioactive compounds. Fermentation is a promising method to enhance these components. This study aimed to determine the optimal fermentation time using Lactobacillus plantarum to maximize the bioactive content of red galangal flour. A Randomized Block Design was employed, with fermentation times ranging from 1 to 7 days. The fermented flour was extracted using a two-step aqueous maceration process. Total phenolic content (TPC) and total flavonoid content (TFC) were analyzed spectrophotometrically. The results showed that fermentation significantly increased both TPC and TFC compared to the unfermented control. The optimal fermentation duration was 5 days, yielding the highest TPC of 1100.74 mg GAE/100 g and a significantly higher TFC of 34.30 mg QE/100 g (P 0.01). After this point, the bioactive content began to decline. This study demonstrates that a 5-day fermentation period is optimal for enhancing the phenolic and flavonoid compounds in red galangal flour, highlighting a viable method for developing functional food ingredients.

Abstract

Red galangal (Alpinia officinarum) is a medicinal herb rich in phenolic and flavonoid compounds, which offer significant health benefits. This study aimed to optimize the fermentation duration using Lactobacillus plantarum FNCC 0026 to maximize the bioactive content in red galangal flour. The research method involved fermenting red galangal flour for periods ranging from 1 to 7 days, followed by drying and a staged maceration extraction using 70% ethanol. The analyzed parameters included the final pH of the fermentation medium, total phenolic content (TPC), and total flavonoid content (TFC). The results indicated that a longer fermentation period decreased the pH, although no significant differences were observed among the 1- to 7-day treatments. Otherwise, the fermentation duration had a highly significant effect on TPC (p0.01) and TFC (p0.05). The highest accumulation of both TPC and TFC was achieved after 5 days of fermentation, with values of 1468.78 mg GAE/100 g and 41.49 mg QE/100 g, respectively. It is concluded that a 5-day fermentation period is the optimal duration for enhancing the bioactive compounds in red galangal, offering an effective biotechnological approach for developing functional food ingredients.

Abstract

The decline in red spinach (Amaranthus tricolor L.) production in Indonesia has prompted the need to explore effective and environmentally friendly alternatives to conventional fertilizers. This study examines the potential of cow biourine as a liquid organic fertilizer to increase the yield and nutritional quality of red spinach. The field experiment used a Randomized Block Design with five levels of biourine concentration (0, 200, 400, 600, 800 ml). The variables measured included growth components (fresh weight and productivity) and quality (protein and calcium content). The analysis results showed that the application of cow biourine significantly increased fresh weight, productivity, and calcium content. A dose of 400 ml proved to be the optimal treatment with a wet weight of 120.16 g, a productivity of 4.71 tons/ha, and a calcium content of 469.83 ppm.

Abstract

Land degradation challenges rice productivity in Indonesia, demanding innovative agronomic solutions. This study evaluated the interaction between humic acid-coated biochar rates and plant spacing on the growth and yield of rice (var. IR-64). A field experiment using a factorial Randomized Complete Block Design was conducted in Malang. The treatments used a 2 factorial, the first factor included four biochar rates (0, 5, 10, and 15 t ha⁻¹) and the second factor used three plant spacings (20x20, 20x30, and 20x40 cm). The result showed a significant interaction (P 0.05) between biochar rate and spacing for the number of tillers and stem diameter. The highest tiller count (35.27) was recorded in the 5 t ha⁻¹ biochar rate, combined with 20x40 cm spacing. While the main effect of biochar on yield was not significant, plant spacing had a dominant impact; the 20x30 cm spacing yielded the highest grain weight per plot (8.74 kg). These findings highlight that rice yield optimization depends on the specific synergy between soil ameliorants and planting density
