Abstract

Mangrove ecosystems in Tanjung Rejo Village, Percut Sei Tuan Sub-district, Deli Serdang experienced a lot of land conversion in the form of residential, agricultural and plantation lands. This causes abrasion in this region because there is no protection from waves and sea waves in this region. Land conversion and abrasion caused many mangrove trees to die. Mangrove trees that died were only used on the trunk, twigs and leaves by local residents. Many parts of the dead mangrove roots are not utilized. This community service activity aims to provide information and skills to partner groups about the making of MAROCA. Through this activity, partners will gain knowledge and skills in making MAROCA so that materials that are not initially valuable like dead mangrove roots become useful. Based on the description of the problem and the purpose of this community service activity, the activities that have been carried out are counseling about the manufacturing of MAROCA, giving leaflets for the procedures for making and providing tools and materials. The results obtained are increased knowledge and skills of partners about the benefits of dead mangrove roots as economically valuable handicrafts.

Abstract

AbstractMoral value education is both a demand and a need for human beings as amanifestation of togetherness in terms of nations and countries with a variety ofproblems. There are a lot of problems, such as global terrorism andmultidimensional crises, which one country cannot solve on its own because to doso it needs other countries supports. Moral value education is an alternativeproblem solution which is local, regional, national, and international in nature. Ithas become a global issue in several countries (Indonesia, Malaysia, India, andChina) and it has some differences and similarities. The differences result from thecountries different ideologies. However, such countries emphasize moral valueeducation on moral ethic values, especially on values related to human rights thatare universal and global in nature. The concept of moral value education proposedby Kohlberg and Miller tends to be individualistic. Therefore, its needs to becomplemented by taking account of the paradigm proposed by Capra that humanlife is built on the basis of a systemic and holistic view of life, one which is notpartial and individualistic. In its implementation, it needs an appropriate approachand a relevant method and technique. The approaches to moral value educationinclude inculcating, modelling, facilitating, and skill development approaches, andthe methods include dogmatic, deductive, inductive, and reflective methods.Keywords: moral value education, global perspective

Abstract

This work aimed to synthesize MnFe2O4 nanoparticles using the coprecipitation method. Manganese chloride dihydrate (MnCl2.4H2O) and iron sand from South Cianjur, Indonesia, were used as a precursor for MnFe2O4 nanoparticle synthesis. The iron sand elements and compounds were tested using X-Ray Fluorescence (XRF). MnFe2O4 nanoparticle was characterized using X-Ray Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX), and Vector Network Analyzer (VNA). The X-Ray Fluorescence test result showed that 70.54% of South Cianjur contained iron sand. The SEM test result showed that the nanoparticles have an average size of  73.75 nm with a round shape, which was attributed to the agglomeration process. The EDX test result showed that the synthesized nanoparticle contained only Mn, Fe, and O elements without contaminants. The XRD test result showed that the crystal phase of MnFe2O4 was formed with a crystal size of less than 27 nm. The largest reflection losses in the 11.5 - 12.5 GHz range were found in MnFe2O4 with 1:2 variation, i.e., 35.08 dB. This study found that adding iron sand increases MnFe2O4 microwave absorption.

Abstract

This study aimed to synthesize iron sand-based Copper Ferrite (CuFe2O4) using the coprecipitation method. The iron sand was taken from South Cianjur and used as a Fe cation source to synthesize CuFe2O4 nanoparticles. Three composition variations of CuCl2.6H2O and iron sand (Fe3O4) were employed, i.e., 1:1, 1:2, and 2:1. Samples were characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy - Energy Dispersive X-Ray (SEM-EDX), and Atomic Adsorption Spectroscopy (AAS). The XRD analysis exhibits three synthesis-phase results: CuFe2O4, Fe2O3, and CuO. The produced CuFe2O4 has two crystal structures: t-CuFe2O4 in 1:2 variation and c-CuFe2O4 in variations 1:1 and 2:1. Adding Cu resulted in smaller crystal size and higher lattice parameters. SEM-EDX analysis of 1:2 sample variation showed a round-shaped particle of 102.57 nm. AAS analysis showed that the increased mole of Cu decreases the heavy metal, including Pb and Mn, adsorption capacity. The largest adsorption capacity was found in the 1:2 (60.698 mg/g).

Abstract

The manufacture of biodegradable plastics with the main ingredients of talas beneng (Xanthosoma Undipes K. Koch) starch, chitosan, and glycerol as a plasticizer has been carried out by various additions of starch and reduction of chitosan. Initial assessment of talas beneng starch reveals: starch content - 20.51%, water content - 8.58%, fat content - 12.71%, and protein content - 3.51%. Physical testing of biodegradable plastic produces thickness values ranging from 0.166 mm to 0.234 mm, tends to meet JIS Z-1707: 2019 standards, density value is 1.674 g/cm3, and the lowest water absorption value is 20.51%, both meet SNI 7188: 2016 standards, and there is a decrease in mass every week for 28 days in the biodegradation test.

Abstract

Edible films present an eco-friendly alternative for food packaging compared to traditional plastic materials. This study investigates the effects of glycerol and sorbitol plasticizers on the properties of edible films. The research involves crafting these films using porang (Amorphophallus Oncophyllus) starch. Glycerol plasticizers were incorporated at a concentration of 100%, while sorbitol was utilized at varying levels (0%, 25%, 50%, 75%, 100%) to evaluate their impact on film characteristics. The films were produced using the melt intercalation method at a gelatinization temperature of 80°C and a firing temperature of 70°C. Notably, the most favorable physical test outcomes were observed with adding 100% sorbitol, including thickness, density, water absorption, and degradability improvements. Meanwhile, adding 25% sorbitol yielded the highest tensile strength and elongation values.
