This study aimed to analyze the factors influencing sustainable livelihoods in Alamendah Tourism Village, Rancabali District, Bandung Regency, which has rapidly developed through the agritourism sector. A quantitative approach with survey methods was employed, involving 100 respondents selected through probability sampling techniques from a total population of 7,899 households. Primary data were collected through interviews, observations, and questionnaires. Subsequently, data were analyzed using multiple linear regression to determine the effects of age, education, income, natural capital, financial capital, social capital, human capital, and physical capital on sustainable livelihoods. The results showed that simultaneously all independent variables significantly influenced sustainable livelihoods. However, partially, only natural capital, social capital, human capital, and physical capital had a significant positive effect. Meanwhile, the variables of age, education, income, and financial capital showed no significant effect on sustainable livelihoods. This research recommends the importance of increased investment and attention towards natural, social, human, and physical capital as key strategies to support sustainable agritourism development in Alamendah Tourism Village.

Preservation techniques have been widely applied in food processing. One of the commonly used methods is the addition of synthetic chemical substances, but this can have negative impacts on human health and the environment. Therefore, there is a need for alternative natural preservatives, such as sappan wood (Caesalpinia sappan L.). Sappan wood is a plant species that can be utilized as a natural preservative in food products and possesses various biological benefits, including anti-inflammatory, antioxidant, antivirus and antibacterial properties. This study aims to analyze the relationship between the concentration of sappan wood extract and its antimicrobial activity, as well as to compare the effectiveness of liquid and powder extracts in inhibiting microbial growth. The research employed a Simple Linear Regression method, where variable X represented the concentration of sappan wood extract (%) and variable Y represented the inhibition zone diameter of microbial growth (mm), with concentrations of 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, and 80%. Based on the results of antimicrobial activity testing, both liquid and powdered sappan wood extract exhibited strong antimicrobial activity, indicating potential as a natural preservative. The effectiveness of the extract in inhibiting microbial growth increased with higher extract concentrations. This finding demonstrates a strong and positive linear relationship between extract concentration and microbial growth inhibition.

Sweet potato is one of the food ingredients promoted by the government for its potential to replace wheat flour, and its starch can be used as a substitute material of 50-100%. The purpose of this research is to analyze the effect of the level of preference or acceptance of panelists towards pie crust with sweet potato starch substitution and to describe the physicochemical properties and color of the pie crust. This study conducted five treatments of pie crust, namely pie crust with 100%, 75%, 50%, 25%, and control substitutions of sweet potato starch. Data analysis was performed using One Way ANOVA at a 5% significance level, followed by a DMRT test if there were significant effects. The pie crust with 75% sweet potato starch substitution was the panelists' best choice in terms of color, taste, aroma, texture, and overall. There were no significant effects found on the moisture content and fat content of the pie crust. The results for ash content, protein, carbohydrates, L color, a color, and b color of the pie crust showed significant effects.

Potensi Ekstrak Beberapa Jenis Tanaman dalam Meningkatkan Stabilitas Oksidatif Minyak Kedelai

Soybean oil is one of the vegetable oils with a high content of unsaturated fatty acids; however, it is highly susceptible to oxidation, which can reduce its quality. Prevention is commonly carried out by adding synthetic antioxidants such as BHA, BHT, and TBHQ, which may pose potential adverse effects on health. The use of antioxidants derived from natural sources has therefore become increasingly preferred. Several plant extracts, including marigold flowers, eggplant peel, parsley leaves, olive leaves, jackfruit peel, as well as mixtures of pomegranate leaves, citrus leaves, and beet leaves, have been proven to enhance the oxidative stability of soybean oil by reducing peroxide values, limiting the formation of secondary oxidation compounds, and protecting unsaturated fatty acids. Innovative formulations such as nanoemulsions, acid hydrolysis, and encapsulation have also been shown to improve the efficiency and stability of bioactive compounds. The purpose of this article is to review recent studies on the utilization of plant extracts as natural antioxidant sources for addition to soybean oil. The findings indicate that extracts from various plant species have the potential to improve the oxidative stability of soybean oil.

Dampak Penambahan Ragi Tempe terhadap Kualitas Virgin Coconut Oil

Hendrawan Hendrawan — 2025-08-30

Virgin coconut oil, or VCO, is a high-quality oil extracted from fresh coconut flesh without heating or the use of chemicals. This oil is characterized by low water and free fatty acid content, a clear color, a distinctive aroma, and a shelf life of more than 12 months. With advancements in VCO production, fermentation with tempeh yeast as a starter is now possible. This approach has proven effective in maintaining VCO quality, particularly its antioxidant and fatty acid content, as it does not require high temperatures. This research will be conducted in April 2025 at the Chemistry and Processing Laboratory of the Faculty of Agriculture, Ma'soem University. The aim is to measure the impact of tempeh yeast addition on the properties of VCO. The experiment used a Randomized Block Design (RBD) experiment, which included six treatments of tempeh yeast concentrations (0.5%, 0.8%, 1.1%, 1.4%, and 1.7%) with five replications. The results will be statistically analyzed using Analysis of Variance, and if significant differences are found, they will be followed up with Duncan's Multiple Range Test (DMRT) at a 5% significance level. The research findings indicate that tempeh yeast concentration significantly influences VCO quality, as evaluated by water content, fatty acid content, and yield. The higher the tempeh yeast concentration, the better the VCO quality in terms of water content and yield, although the free fatty acid content also increases.

Agroindustry is a combination of the words agriculture and industry, referring to businesses/industries that primarily use agricultural raw materials. Additionally, agroindustry can also mean industries that produce products for agricultural production (agricultural inputs). One example of agroindustry for agricultural inputs is the liquid organic fertilizer agroindustry. The existence of liquid organic fertilizer agroindustry is generally run by the community, either individually or in groups, thus requiring an economic profitability study to determine the ability to generate profits from the capital invested in that agroindustry. The issues examined in this study include the total cost value, total revenue, income, and profitability of the liquid organic fertilizer agroindustry in a single production process in Cicalengka Wetan Village, Cicalengka District, Bandung Regency. The sampling technique was conducted through purposive sampling at the Bangbara Sadulur Makmur Cooperative. The data analysis was conducted descriptively and quantitatively. The research results indicate that the production output of the liquid organic fertilizer agroindustry in one production process reaches 5,000 liters, with a selling price of Rp. 75,000 per liter. The total revenue obtained is Rp. 375,000,000, and the income earned is Rp. 7,726,707.86. The profitability value of the liquid organic fertilizer agroindustry in Cicalengka Wetan Village in one production process is 2.10 percent, meaning that the ability of the liquid organic fertilizer agroindustry to generate profit is 2.10 percent of the capital invested in one production process
