Exergy Analysis in the Application of Exhaust Heat Utilization Through Diesel Engine Cooling Unit for Organic Rankine Cycle
Get PDFA Very rapid population growth has resulted in fossil energy being gradually depleted and environmental pollution getting worse. So far, burning fossil fuels has produced about 40% of global carbon dioxide (CO2) emissions, which are considered a major source of greenhouse gases. The Internal Combustion Engine (ICE) has become the main power source for cars, trucks, locomotives, and ships. In ordinary diesel engines, less than 45% of the fuel energy can be converted into useful work output from the crankshaft, and the remaining energy is largely lost through exhaust gases and jacket water. One way that can be done is to utilize the waste from the internal combustion engine (ICE). This method uses the Organic Rankine Cycle (ORC) system by utilizing the wasted heat generated by the Diesel engine when operating, through the engine coolant coming out of the engine gap (water jacket) to the radiator. In this study, the study focused on the exergy analysis of each component in the ORC system integrated in the diesel engine cooling unit which was simulated using Aspen Plus software. The analytical method used in this study is the exergy method with variations in ambient temperature of 20oC, 21oC, 22oC, 23oC, 24oC, 25oC, 26oC, 27 oC, and 28 oC using the working fluid R141B. The results showed that the greatest exergy destruction was found in the components of the pump, evaporator, and turbine

Fly ash material as industrial waste has been categorized as non-B3 waste by the government so that the use of Fly Ash can be optimized to maintain environmental sustainability and become a catalyst for driving the community's economy. This study with a 1: 2 ratio mortar material added with fly ash material to analyze the mechanical properties of the material using experimental testing methods on 3 variations of fly ash material compositions in sequence 10%, 30%, and 50% aims to obtain compressive strength characteristics and mass percentage. The test results provide the highest compressive strength value data on 10% fly ash material of 28.10 MPa while other composition variations tend to show a decrease in the ability of material resilience properties in sequence of 9.36% and 20.32%. The mechanical properties of compressive strength meet the quality requirements of SNI 03-0691-1996 for implementation on paving blocks of type B quality and SNI 2442-2020 for application on concrete curbs. The influence of mass composition provides a positive contribution creating an increasing trend towards the mass percentage where the response of fly ash variations is respectively 20.74% and 14.33%
Penerapan Hukum Bagi Pelaku Aborsi Secara Ilegal
Get PDFThe enforcement of law concerning illegal abortion encompasses a range of criminal penalties outlined in the Criminal Code (KUHP) and other legislative frameworks. These legal actions are not only directed at the primary perpetrators, such as healthcare providers or individuals who perform abortions, but also extend to others involved, including parents or partners who assist or support the act. The purpose of this article is to examine the factors contributing to the occurrence of illegal abortions and the application of legal measures against those who commit them. The methodology employed in this study uses a normative approach, utilizing a literature review of relevant laws and court decisions. The findings reveal that although the legal framework imposes severe penalties on individuals involved in illegal abortions, various obstacles hinder effective law enforcement. These include lack of oversight, ineffective enforcement mechanisms, and socio-economic factors that contribute to the high prevalence of illegal abortion. Therefore, collaborative efforts are needed to raise legal awareness, improve regulations, and implement more compassionate strategies in addressing illegal abortion cases

Analisis Aktor dan Dinamika Collaborative Governance dalam Pengelolaan Ruang Terbuka Hijau (RTH) Pagutan Kota Mataram
Get PDFPenelitian ini didasari oleh pergeseran fungsi RTH yang seharusnya mulai melibatkan banyak actor agar tercapainya pemanfaatan RTH secara maksimal, baik secara ekologi, lingkungan maupun social budaya. Namun, dalam praktiknya, pengelolaan dan pengembangan RTH masih menghadapi berbagai tantangan, seperti minimnya keterlibatan multi actor sehingga menjadikan beban yang cukup tinggi bagi DLH. Sehingga tujuan dari penelitian ini untuk mengidentifikasi aktor kunci yang berperan dalam proses koordinasi, dan dapat mengungkap pola collaborative governance dalam setiap tahapnya melalui metode SNA (Social Network Analysis) sehingga dapat menjawab tantangan pengelolaan dan pengembangan RTH. Hasil dari penelitian ini sendiri adalah DLH sebagai faktor dominan atau sebagai aktor kunci, disetiap tahapan yaitu tahapan assessment, initiation, deliberation, dan implementation sudah berjalan, tetapi tidak seimbang. DLH tampil sebagai aktor dominan di semua tahap, sementara dinas lain hanya berperan periferal atau bahkan tidak berkontribusi. Sehingga Penelitian ini merekomendasikan bahwa pengelolaan RTH ke depannya dapat dilakukan transisi dari pola jejaring “star network” menuju “collaborative network” yang lebih seimbang, dengan distribusi peran antar aktor, Pemerintah Kota Mataram dapat menetapkan regulasi atau kebijakan khusus yang mengatur kolaborasi lintas dinas dalam pengelolaan RTH, agar keberlanjutan lebih terjamin dan dapat membentuk forum komunikasi khusus pengelolaan RTH sebagai forum komunikasi aktif antar aktor
