Abstract

The Government-to-Government (G2G) program significantly increases the number of Indonesian Migrant Workers (PMI) in Korea. As a developed country, South Korea is committed to protecting all workers in its territory, including migrant workers from Indonesia. However, the employment social security of the South Korean government is not fully able to cover the risks and needs of PMI. Protecting migrant workers' rights to social security is important. It is also the responsibility of the Indonesian government through BPJS Employment, not only to ensure equal treatment in social security for migrant workers but also to expand social security coverage for populations that are currently unprotected. Therefore, it is important for employment social security administrators to increase the probability of migrant workers becoming BPJS Employment participants. Using the logistic regression method and Sakernas data for August 2021, it was found that migrant workers who work in the formal sector, with work contracts, and have BPJS Health membership have a higher tendency to become Employment Social Security participants.

Abstract

Advances in information and communication technology have changed the paradigm in the agricultural sector, especially in the application of the Internet of Things (IoT). An IoT-based monitoring system is an innovative step as there is an increasing need for technology in the agricultural sector and the development of the world of education. SMK Negeri 3 Salatiga, majoring in agribusiness, has great potential in hydroponic agriculture of lettuce plants, but there is no use of IoT technology in it. Hydroponic learning activities at SMK Negeri 3 Salatiga still use manual hydroponic learning media, which results in the competence possessed by teachers and students not being competent in IoT technology, especially its application to hydroponics. Meanwhile, if adjusted to learning outcomes, students should be able to fertilize plants in a modern way. The purpose of this study is to develop and implement hydroponic monitoring learning media based on Internet of Things technology. The application of learning media aims to improve the understanding or competence of teachers and students at SMK Negeri 3 Salatiga. The research methods used are Research and Development with the ADDIE development model, as well as one group pre-test and post-test design research design with 31 samples as a competency improvement test. This study resulted in 26 participants out of 31 participants experiencing an increase in competency in the results of the post-exam exam. So, it can be concluded that there is an increase in the competence of using hydroponic IoT by 83% among teachers and students.

Abstract

Biodegradation is a physical decomposition of the substrate caused by the activity of microorganisms by producing products that have benefits for humans. Lignocellulose degrading fungi are microorganisms that play a role in the process of decomposing organic waste. The biodegradation rate of each type of lignocellulose degrading mold is different. The purpose of this research is to comprehensively analyze and compare the rate and level of biodegradation of leaf waste in lignocellulolytic molds isolated from the campus environment of Universitas Negeri Semarang, as well as to identify and evaluate the type of lignocellulolytic mold that shows the highest efficiency in the rate and level of biodegradation of leaf waste. The method used in this research is quantitative method, by measuring the mass ratio and pH of leaf waste media before inoculation and after inoculation. The results of this study are the rate of leaf waste biodegradation based on the ratio of leaf waste mass by Trichoderma koningiopsis mold isolate of 0.015 grams/day, while by Trichoderma erinaceum mold isolate of 0.002 grams/day. Then the rate of leaf waste biodegradation based on the pH change value of leaf waste by Trichoderma koningiopsis mold isolate is higher with a pH change value of 0.3 when compared to the Trichoderma erinaceum mold isolate with a pH change value of 0.1. The superior performance of Trichoderma koningiopsis highlights its potential application in optimizing organic waste decomposition systems and provides a scientific basis for selecting lignocellulolytic fungi in sustainable waste management programs.
