Abstract

Lapangan panasbumi X terletak pada jalur gunung api aktif yang pembentukannya dikontrol oleh proses-proses geologi dan diindikasikan oleh adanya struktur geologi yang merupakan salah satu penyebab timbulnya gempa. Dalam periode bulan Januari 2013 hingga Agustus 2014, tercatat sebanyak 409 event gempa  mikro. Hasil penentuan nilai Poisson’s ratio yang diperoleh dari analisis kecepatan gelombang seismik, diketahui bahwa nilai Poisson’s ratio di lapangan panasbumi X adalah dominan rendah sehingga lapangan panasbumi X dapat dikatakan sebagai lapangan dengan sistem panasbumi dominasi uap. Pola distribusi Poisson’s ratio menunjukkan bahwa sistem recharge di area lapangan panasbumi X berlangsung dengan baik. Hasil overlay antara sebaran nilai Poisson’s ratio dengan data pendukung menunjukkan bahwa fluida injeksi mengalir dari sumur injeksi menuju sumur produksi melalui struktur geologi yang terdapat di area lapangan panasbumi X.

Abstract

A decline in groundwater quality in the coastal part of Tangerang Regency, which directly borders the Java Sea, has been identified in recent years. This content analysis research examines the suitability of the coast of Tangerang Regency, especially the Kosambi sub-district, as an industrial area based on the RPIJM of the Tangerang Regency government. Groundwater quality and the impact of intrusion in the study area were analyzed based on secondary data obtained from the Groundwater and Subsidence Monitoring System of the Ministry of Energy and Mineral Resources at 15 water sample points. The parameters analyzed include physical, chemical and inorganic water parameters. The results obtained from the analysis of various parameters show that groundwater in the study area is polluted by seawater. The plan to develop an industrial area in the study area will certainly impact increasingly severe levels of intrusion in the study area if the plan does not pay attention to preserving groundwater resources.

Abstract

Laundry services are essential to support other industries, such as tourism and health. Hospitals, hotels, and restaurants are customers of the laundry industry. Occupational health and safety risks in the laundry sector have become a government concern through the Ministry of Health of the Republic of Indonesia issuing the Hospital Laundry Ergonomics Guide. This activity aims to provide knowledge regarding occupational safety risk control for the laundry service industry. Workers in this sector face risks of ergonomics and chemical hazards. Ergonomics risk comes from lifting and transporting linen material in sorting, washing, and drying activities up to the final process. Workers need to be given the insight to care about safety and how to control the hazards they face. By carrying out this activity, it is hoped that participants will become more aware of occupational safety risk control to improve their quality of life.

Abstract

Pesticides are all chemicals and other substances, as well as microorganisms and viruses, which are used to eliminate or prevent pests and diseases that damage plants, plant parts or agricultural products. The use of pesticides in the agricultural sector is still widely used even though pesticide prices are increasing every year. Indramayu is one of the largest agricultural lands in West Java, so the majority of Indramayu residents earn their living as farmers. The problem that farmers often encounter in using pesticides is a lack of knowledge and low awareness, which results in a lack of behavior to prevent the consequences of using pesticides, such as a lack of use of personal protective equipment by farmers when spraying with pesticides. The aim of the Community Partnership Program (PKM) is to help increase knowledge and understanding of how to prevent the impact of pesticide use on the farming community in Pawidean Village. This PKM takes the form of assistance, counseling or outreach, showing videos and making posters for farmers. Farmers hope that the results of this PKM will increase farmers' understanding of practices to prevent health impacts caused by the use of pesticides.

Abstract

Tangerang is counted among Indonesia's fastest-growing industries and population since it is located near the capital. At the current rate of population growth, the population by 2035 is expected to reach more than 2 million by appliying the geometric method. Rapid population growth has severe environmental damage. A simple linear regression calculation was applied to predict the Tangerang waste generation and it is expected to grow to 1,57 million tonnes by 2035. The Pearson's correlation was used to examine the impact of population growth in Tangerang on waste generation. Overall, there is a positive correlation between population growth and waste generation. The increase in the amount of waste can affect the formation of leachate. Rawa Kucing is the main Tangerang landfill that implements an open dumping system in its waste management. One of the negative impacts of the open dumping system is the potential for leachate generation. This study performed a simple calculation of leachate volume to illustrate leachate generation in Rawa Kucing. The more leachate produced, the greater the level of contamination since it contains highly toxic components, and it will escape from the Rawa Kucing landfill, contaminating the groundwater, potentially polluting the environment and harming human health.
