Abstract

Plants contain compounds that can be considered as antimicrobials. The community of Turi Putih Village have used plants that have medicinal properties to treat certain diseases, especially those caused by bacteria. For this reason, it is necessary to conduct research on the use of medicinal plants and antibacterial tests from plants originating from Turi Putih Village. The purpose of this study was to determine the diversity of medicinal plants, plant parts used, preparation and use of medicinal plants by the local community, as well as the antibacterial potential of medicinal plants that have High score of Use Value (UV) and Fidelity Level (FL) ​​to treat those diseases. Data was collected by using semi-structural interviews and respondents were chosen by purposive sampling. To analyze the data, we adopted qualitative and quantitative ethnobotanical technique. Qualitative, namely descriptive methods to make an inventory of the composition of medicinal plants and preparation and use by the community, and quantitative to see the most commonly used and most preferred species ethnomedicinal plant species for treating certain ailments. . Based on interviews with respondents, the community uses 44 species of medicinal plants, 40 genus that belong to 26 plant families to treat 19 diseases caused by bacteria. Based on UV and FL scores, mint leaves (Mentha piperita) and kencur leaves (Kaempferia galanga) had the highest scores. The results showed that mint leaves and kencur leaves have antibacterial activity by forming an inhibition zone against Staphylococcus aureus and Escherichia coli. In this study, extract from leaf of K. galanga appeared to be more potent than that of leaf of M. piperita, and produced consistent level of inhibition of bacterial growth. Since it was revealed that the leaves extract of Kaempferia galanga has the ability to inhibit the growth of Staphylococcus aureus – food – poisoning organism, hence, it would be interesting to investigate the potentially of this plant for possible application in foods to promote safety.

Abstract

Bioplastics, an environmental friendly materials, attracting interest to many scientists around the world. Cassava starch may used as a major ingredient for bioplastics production. The addition of cellulose could improve the quality of starch base bioplastics. Cellulose used for thispurpise is mainly extracted from wood. Extraction of cellulose from wood materials is not easy. Removing contaminant particularly lignin is the major obstacle. The use nata de coco, a pure crystalline cellulose, may of great choice to replace cellulose of wood origin. It is the aim of this study to search the possibility of using nata de coco as filler replacing cellulose of wood origin for the production of bioplastic using cassava starch. The effect of nata de coco as a filler on the quality of bioplastics was studied using a Central Composite Design (CCD) and Response Surface Analysis (RSA). The ratio of tapioca and nata de coco and the ratio of nata de coco and glycerol were evaluated. The performance of bioplastics was measured semi qualitatively based on the structure, color, and its similarity to synthetic plastics. The result shows that the quality of bioplastics affected by nata de coco linearly when the maximum of nata de coco used up to 40% (v / v). Bioplastics may be prepared using 10% (w / v) tapioca, 3% (w / v) glycerol and 40% (v / v) nata de coco. The average degree of swelling of bioplastics is 18.75%, an average tensile test of 0.01494 kgf / mm2 and an average elongation 14.4056%. The results of this study indicate that nata de coco may be used as a filler in the manufacture of starch-based bioplastics re placing wood based cellulose.

Abstract

Food security is a fundamental aspect of human welfare, ensuring nutritional adequacy to support daily activities and enhance quality of life. This study examines food security in Malasari Village, focusing on food availability, procurement methods, and dietary patterns. Data were collected through questionnaires, observations, and documentation, then analyzed descriptively using charts, graphs, and narrative presentation. Results indicate that 56% of households rely on private agricultural land, 63% utilize home gardens for food crops, and 66% depend on private livestock for food sources. Staple food consumption predominantly consists of rice (84.06%), followed by cassava (10.14%) and bananas (5.80%). Supplementary food intake includes vegetables (24.18%), fruits (24.18%), fish (20.94%), eggs (10.7%), chicken (9.3%), nuts (9.3%), and meat (1.4%). The findings suggest that Malasari Village exhibits relatively high food security, supported by diversified local food production and accessibility. This study underscores the importance of sustainable agricultural practices and equitable food distribution to maintain community resilience.
