Abstract

Kebon Gedang Block is one of the few areas of natural dye batik craftsmen in Indonesia. The activity of using natural dyes for batik has been carried out from generation to generation. This study aims to analyze the transfer of ethnobotanical knowledge of natural dyes based on age class (KU), analyze ways to regenerate and analyze the policy scheme for retention of ethnobotanical knowledge of natural dyes in the Kebon Gedang Block. The main methods used in this study were semi-open interviews, observation, and documentation. The selection of respondents was carried out by purposive sampling by considering age (years), namely I (30-39), II (40-49), III (50-59), IV (> 60). The results showed that the level of knowledge of natural dyes and retention was highest in KU III because the people were still healthy, strong, and generally still actively following the development of the batik industry. However, KU III is the group with the highest change in knowledge and is feared to be lost. While at other KU levels, the inheritance of knowledge is still going well. The policy of retaining ethnobotanical knowledge of natural dyes can be carried out in several ways, including by creating books, booklet or electronic sites about knowledge of natural dyes, as well as by registering intellectual property rights. This research can record the current state of knowledge so that efforts can be made to avoid losing this knowledge.

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

Jahe merupakan tanaman herbal dengan peminat yang tersebar di seluruh dunia. Menurut data yang disebutkan oleh Food and Agriculture Organization di tahun 2019, produksi jahe di Indonesia sebanyak 174 ribu ton dan Indonesia menempati urutan keenam sebagai negara dengan hasil produksi jahe terbesar di Asia. Tingginya minat masyarakat terhadap jahe mengakibatkan melonjaknya produksi jahe sehingga muncul permasalahan baru salah satunya kerusakan pada rimpang jahe. Sehingga alternatif pengendalian dengan fungisida alami diperlukan. Buah pinang memiliki kandungan senyawa bioaktif seperti saponin, flavonoid, tannin, phenol, steroid, alkaloid yang dapat berperan sebagai anti-kapang. Penelitian ini bertujuan untuk mengetahui pengaruh penambahan ekstrak buah pinang muda terhadap  pertumbuhan kapang pada rimpang jahe segar dan simplisia kering rimpang jahe. Hasil yang diperoleh pada penelitian ini adalah adanya penghambatan pertumbuhan kapang dari penambahan ekstrak dengan pengenceran. Sedangkan perlakuan ekstrak tanpa pengenceran kurang memberikan pengaruh dalam penghambatan pertumbuhan kapang.

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.
