Abstract

The process of making a piece of woven fabric using natural dyes takes a long time, starting from collecting the materials to dyeing the yarn. This causes the weaving activists in the Dahlia Farmers Group to only be able to weave one piece of cloth in ± 3-4 days or even 1 week. The Dahlia Farmers Group has used natural dyes for generations, but the use of natural dyes is only on woven yarn and has not known and tried to make ecoprint. This prompted the Service Team to provide skills in the form of socialization and ecoprint training as a new innovation in the use of natural dyes. In addition, this training is also to instill knowledge and stimulate ideas about environmentally sustainable entrepreneurial products, thereby increasing income, and introducing additional products outside of traditional weaving. The approach adopted in this training, in addition to socialization explaining the principles of ecoprint, also focuses specifically on pounding techniques. Based on the results of the activity, it appears that the partners are enthusiastic and have a great interest in the training and the products produced, in the form of plant-patterned fabrics and bags with a variety of colors.

Abstract

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus, transmitted through the bite of the Aedes aegypti mosquito. The high number of DHF cases is influenced by a weak immune system and high mosquito population density. People generally use synthetic insecticides to prevent mosquito bites, but long-term use, such as mosquito coils and lotions containing DEET, has the potential to cause side effects. Therefore, safer and more environmentally friendly alternatives are needed, such as botanical insecticides. Citronella (Cymbopogon nardus L.) is one plant that has the potential to be a mosquito repellent because it contains the compounds geraniol, citronellal, and citronellol. Although some members of the Dahlia farmer group have citronella plants in their yards, their use as a mosquito repellent has not been optimized. Community Service (PKM) activities are carried out through outreach and training on making bio-spray from citronella as a mosquito repellent for dengue prevention. This activity aims to educate the public, especially housewives who are members of the Dahlia farmer group, about the dangers of dengue fever, the risks of long-term use of chemical insecticides, and the development of plant-based bio-sprays as an alternative solution to reduce the number of dengue fever transmissions.

Abstract

Objective: This study aimed to assess the quality of complete feed wafers with different plant protein sources for a feed of small ruminants.Methods:The research was conducted in May-September 2022. The research method used a completely randomized design (CRD) with 4 treatments and 4 replications. The method used in this study was Completely Randomized Design (CRD) with 4 treatments, namely R0 = Wafer with an animal protein source (Fish meal) (Control), R1 = Wafers with protein source Sesbania grandiflora, R2 = Wafers with protein source Gliricidia sepium. R3=Wafer with protein source Leucaena leucocephala.The research variables consisted of physical quality (moisture content, wafer density, specific gravity, water absorption) and nutritional quality (dry matter, organic matter, crude protein, crude fat, crude fiber, and nitrogen free extracts). Data analysis according to the Analysis of Variance procedure using SPSS version 21.Results:The results showed that the use of plant protein sources had no significant effect (P>0.05) on water content and wafer density but had a significant effect (P<0.05) on specific gravity and water absorption capacity. The use of plant protein sources can increase the value of water content, wafer density, and specific gravity and reduce water absorption capacity. Meanwhile, the crude protein (CP) content of the wafer had no significant effect (P>0.05) and produced the same value as using fish meal. Other nutritional variables had a significant effect (P<0.05) such as DM, OM, EE and NFE which increased and CF decreased on the use of plant protein sources in making feed wafers compared to the use of fish meal.Conclusions: It was concluded that the use of legumes Sesbania grandiflora, Gliricidia sepium, and Leucaena leucocephala as a source of vegetable protein in wafers could replace fish meal. The three types of legumes had the same effect on the physical and nutritional quality of the resulting product.

Abstract

Rhodamine B is a synthetic dye commonly used, especially in the textile industry. Excessive entry of Rhodamine B into the environment can alter the pH of water, which can disturb microorganisms and animals living in aquatic environments. One way to address the pollution of Rhodamine B is by using activated carbon from sorghum stalk waste. Activated carbon is carbon that has been processed through activation to have pores with a very large surface area, thereby enhancing its adsorption capacity. The aim of this study is to determine the characteristics of activated carbon from sorghum stalk waste and to determine the optimum NaOH concentration in the synthesis of activated carbon from sorghum stalk waste as an adsorbent for Rhodamine B dye. The stages in this study include the preparation of sorghum stalk waste samples, carbonization, and activation of the carbon from sorghum stalk waste using NaOH activator with concentration variations of 2, 3, 4, 5, and 6% for 24 hours. The adsorption process was carried out using the activated carbon from sorghum stalk waste to adsorb Rhodamine B dye. The results of the study showed that the characteristics of the activated carbon from sorghum stalk waste had a moisture content of 4-7.3%, ash content of 2.3-7.6%, and an iodine adsorption capacity of 2,410.67-3,427.11 mg/g. The results of the characterization of activated carbon from sorghum stalk waste overall met the Indonesian National Standard (SNI). The optimum NaOH activator concentration for adsorbing Rhodamine B dye was obtained at a concentration of 6%, with an adsorption efficiency of 88.94%.

Abstract

This study aimed to isolate and identify bacteria from the rumen fluid of Bali cattle and to evaluate their effect as microbial inoculants on the in vitro digestibility of rice straw. The experiment was conducted using a Completely Randomized Design (CRD) consisting of four treatments and four replications. The treatments included rice straw silage with the addition of 0%, 5%, 10%, and 15% of local microorganisms (MOL) derived from cattle rumen fluid. The observed variables included the isolation and identification of bacteria from the rumen fluid, and the assessment of in vitro digestibility, including Dry Matter Digestibility (DMD), Organic Matter Digestibility (OMD), Volatile Fatty Acid (VFA) concentration, and ammonia (NH₃) production. The results showed that the addition of rumen fluid MOL significantly (P<0.05) improved the digestibility parameters. The highest DMD (52.44%) and OMD (47.11%) were obtained from the treatment with 15% MOL. VFA and NH₃ concentrations also increased, indicating enhanced microbial activity and fermentation efficiency. The study concludes that MOL derived from cattle rumen fluid, particularly those containing Bacillus sp., is effective in improving the nutritional quality and digestibility of rice straw
