Abstract

Sengon wood (Albizia falcataria) is chosen as an alternative raw material for the manufacture of pulp has physical and chemical characteristic that meet the standards of raw material for pulp. The most important factors that influence the process of the kraft pulping is the ratio of the cooking liquid (AA charge) which serves to degrade and dissolve so easy to separate lignin from cellulose, while still protecting carbohydrates from degradation so that the resulting yield and good physical strengt. The study began with the preparation of raw materials, cooking by using a variable charge AA 14%, 16%, 18%, 20% and 22%, pulp washing and sheet formation, as well as the analysis of the quality of the pulp. Cooking liquid ratio will affect the yield and quality of pulp, including kappa number, viscosity and brightness. The low use of cooking liquid causes the higher lignin content in pulp and produce wood that is not mature, so the higher the yield, kappa number and viscosity, but lower brightness. While conversely, the higher the cooking liquid use causes more fiber degraded.

Abstract

The rise of epidemics caused by microorganisms such as SARS, bird flu, HIV and COVID-19 has made people use products that contain antiseptics such as soap and hand sanitizers. However, in general, the basic ingredient for making antiseptics comes from alcohol. If you use it continuously, it will dissolve the layer of fat and sebum on the skin so that the skin becomes sensitive, dry and irritated. Antiseptic product development can be done with natural ingredients such as utilizing green betel leaf extract (Piper betle Linn.). It is known that green betel leaf (Piper betle Linn.) Has long been used in traditional medicine and can be a natural antiseptic ingredient for the manufacture of hand sanitizer gel. This study aims to determine the effect of green betel leaf on the antiseptic power in hand sanitizer gel preparations. The materials used in this study were carbomer 940, triethanolamine (TEA), glycerin, sodium metabisulfate, aquadest, and green betel leaf extract obtained from the soybean extraction process. The research was conducted by varying the betel leaf extract 0%, 10%, 20%, 30%, 40%, 50%, 60%, and 70%. The test was carried out by including organoleptic observations (shape, color, smell), homogeneity, preference test, pH, density, viscosity, dispersibility, and bacterial test.

Abstract

Indonesia, as a country with cultural and religious diversity, has villages as important laboratories for strengthening interfaith tolerance. However, social, political, and economic dynamics have created complex challenges, including the potential for religious conflict. However, this is different in Sidomulyo Village, Lumajang, which is inhabited by a multi-religious community (Islam, Catholic, Christian, and Hindu) and multi-ethnic (Javanese and Madurese), serving as an important example in managing this diversity. This village also served as the inauguration site for the BIMA MERDEKA Village, an initiative to strengthen religious moderation and counter radicalism. The purpose of this community service was to analyze superior assets and asset development strategies and to identify outcomes of the asset development program. The method used was the ABCD (Asset-Based Community Development) approach through the 5-D cycle (Define, Discovery, Dream, Design, and Destiny). The results of the community service show that this village has interfaith harmony, local cultural potential, and high social participation. The development strategy involves collaboration between religious leaders and the community in designing programs based on local wisdom. This program has successfully increased awareness of religious moderation and become a model for sustainable diversity management.
