Aluminylum is a metal that has advantages over other metals, such as being lightweight, good at conducting heat and electricity, corrosion resistant, and easy to produce in various forms. The high demand for aluminum also encourages the industry to optimize the utilization of existing resources, one of which is by recycling aluminum waste such as scrap and dross. PT Afan Logam Lestari is one of the aluminum scrap and dross utilization industries in Jombang Regency. In its production activities, PT Afan Logam Lestari produces waste from the aluminum production process which can have an impact on air emissions to the environment and society. Therefore, it is necessary to analyze the impact of air emissions generated from the production process.
This study aims to identify the impact of air emissions arising from the aluminum recycling process with a gate to gate approach, namely the enrichment & crushing process, the melting process, and the casting process. This study uses the Life Cycle Assessment (LCA) method to analyze the impact of air emissions generated from the production process. The analyzed emissions include CO2, SO2, NOx, N2O, CH4, CO, PM, NH3, HCl, HF, Zn, Pb, and H2S. The research phase began with an analysis of the emission load resulting from the aluminum recycling process. The results of the analysis of emission burden, fuel, energy, and raw materials were used in the Life Cycle Inventory (LCI) analysis. Furthermore, impact identification was carried out using the Life Cycle Impact Assessment (LCIA) method. The air emission impacts analyzed include global warming potential, acidification potential, eutrophication, human toxicity, photochemical oxidation, abiotic depletion, fresh water aquatic ecotox, marine aquatic ecotoxicity, and terrestrial ecotoxity analyzed using the midpoint approach, namely CML - IA Baseline. The analysis used Microsoft Excel software with a data base obtained in SimaPro software.

The Heat Transfer Rate of Composite Wall with Series and Parallel Configuration
No full textInsulation serves as a barrier to heat transfer and is therefore crucial for keeping your home warm in the winter and cool in the summer months. A well-insulated and well-designed home delivers year-round comfort while reducing cooling and heating expenditures by as much as 50%, depending on the climate. It follows that greenhouse gas emissions will be reduced as a result. The R-value of the products available can be used to compare the insulating properties of the many options available. The R-value is a measurement of heat flow resistance. When it comes to insulation, the higher the R-value, the greater the level of protection. The strategy for arranging insulating layers in its application influences the rate of heat transfer as well. The value of heat flow/heat transfer rate can be used to determine how much energy is propagated down the insulating wall and how quickly it does so. By using the ANSYS software and the Steady State analysis approach, this study seeks to provide an overview of how much influence the configuration system for installing an insulating wall layer. From the results of the simulation, it can be concluded that the heat transfer rate is lower when the insulating layer installation systems are placed in series than when they are attached in parallel

REFORMING INDONESIAN RAPE LAW: PERKOSAAN TERHADAP LAKI-LAKI
No full textThe criminal act of rape in Indonesia is regulated in several legal regulations, namely the Old Criminal Code, Law No. 23 of 2004 concerning PKDRT, Law No. 12 of 2022 concerning TPKS and Law No. 1 of 2023 concerning the New Criminal Code. However, the regulations regarding rape in these regulations still have gaps to accommodate the development of rape crimes such as rape against men. This article aims to find out and analyze the legal formulation regarding the regulations for the crime of rape in these regulations as well as what the appropriate legal formulation is in regulating the act of rape against men in Indonesia. The method used in this research is normative juridical with library study data collection techniques. The results of the research are that the legal formulation regarding the criminal act of rape contained in several laws and regulations in Indonesia currently still creates a void and legal ambiguity in terms of regulations regarding rape against men. The conclusions and suggestions in this writing are, to reformulate several elements in the formulation of articles regarding rape which still have the potential to cause gaps and ambiguity in the law, so that rape against men can be accommodated. The author suggests that the government review the existing rape articles in light of the current conditions of crime development in Indonesia and for law enforcement officials to further expand their knowledge regarding the development of legal regulations regarding the crime of rape in Indonesia
CLASSIFICATION OF SINAU BARENG SUSTAINABILITY IN SURABAYA USING ATTENDANCE DATA AND SUPERVISED LEARNING
No full textSinau Bareng is one of the educational programs initiated by the Dinas Pendidikan Kota Surabaya, focusing on collaborative learning activities for school-aged children. The sustainability of Sinau Bareng activities relies heavily on participant attendance at each location. A key issue that arises is the absence of participants (tutors and students) in several locations, which prevents the activities from being carried out effectively. Therefore, it is necessary to predict the sustainability of activities at each location based on participant attendance data. This prediction aims to support decisionmaking in selecting and continuing appropriate learning locations. This study compares three algorithms Support Vector Machine (SVM), Random Forest, and Naïve Bayes to determine whichis more suitable for predicting sustainability at each location. The research process follows the CRISP-DM framework, which consists of six stages: business understanding, data understanding, data preparation, modeling, evaluation, and deployment. The dataset used includes attendance records categorized by tutors and students over a period of time, with each record labeled according to its sustainability status. The evaluation results indicate that the best-performing model is the Random Forest algorithm using a 4/5 K-Fold validation split, achieving an accuracy of 93.02%, precision of 86.53%, recall of 93.02%, F1-score of 89.66%, and AUC of 90.48%.. These results suggest that Random Forest is highly effective for handling attendance-based sustainability predictions in community-driven education programs
