Kenyamanan termal merupakan faktor penting yang memengaruhi kualitas hidup penghuni perumahan, terutama di daerah dengan temperatur udara tinggi seperti Kota Bekasi dan Karawang. Penggunaan air conditioner (AC) menjadi solusi umum untuk mengatasi temperatur panas di dalam ruangan, namun efektivitasnya dalam meningkatkan kenyamanan termal masih perlu dikaji lebih lanjut. Metode penelitian ini meliputi pengukuran temperatur dan kelembaban menggunakan Arduino dengan sensor DHT11 dan DHT22 serta perhitungan indeks kenyamanan termal. Penelitian ini bertujuan untuk menganalisis perbandingan penggunaan AC terhadap kenyamanan termal di perumahan serta efektivitasnya dalam menciptakan kondisi termal optimal. Selain itu, penelitian ini juga berfokus pada dampaknya terhadap konsumsi energi guna meningkatkan efisiensi penggunaan AC. Hasil penelitian menyimpulkan bahwa pada kondisi tertentu, kenyamanan termal dapat tercapai hanya dengan memanfaatkan pengaruh udara luar atau cuaca, seperti ketika temperatur dan kelembaban lingkungan berada dalam rentang optimal. Namun, penggunaan AC memungkinkan kenyamanan termal tercapai secara konsisten tanpa bergantung pada kondisi udara luar, bahkan pada saat cuaca panas dan lembap.

Purpose: This study aimed to explore the impact of empowering society and culinary MSMEs on Sustainable Development Goals (SDGs) in West Java, focusing on Sindangmukti Village, Karawang Regency. While prior research has often used a top-down approach, neglecting direct societal impact, this study takes a bottom-up perspective, aligning with implicit SDG principles observed in community services. Research Methodology: The study employed online questionnaires with 505 households in West Java to evaluate water consumption, waste generation, and energy usage patterns. Specific investigations in Sindangmukti Village have measured community service effectiveness regarding SDGs. Results: The study found that Only 19.1% of the participants set AC temperatures within the recommended ranges. Additionally, initiatives to promote a sustainable city strategy and establish energy-efficient culinary MSMEs in Sindangmukti Village resulted in a 29% increase in knowledge among 70 participants and generated $36.71 income from bitter melon chip production within two months. Limitations: However, the study focused solely on Sindangmukti Village, neglecting the diverse cultural and problem landscapes of other villages in the Karawang Regency. Contributions: The findings of this study can inform future efforts to enhance energy, water, and waste efficiency in residential buildings in West Java, thereby fostering awareness of energy conservation, environmental sustainability, and economic resilience.

The increasing population growth in cities will cause environmental detriments such as global warming and ozone depletion. The electricity need will increase in the future due to the higher temperature in the cities, leading to the higher usage of cooling equipment such as freezers. The current study proposed a method to improve the freezer's energy efficiency by using phase change material of dry ice gel. Most of previous studies only focused on the impact of position of phase change materials on the temperature of wall freezer while no previous studies consider the detailed methodology of measurement and the impact of phase change material based on dry ice gel to the variance of wall temperature. The sensor thermocouple type T and data logger ADAM 6018+ were used to measure the wall temperature of the freezer. The results showed that the sensor thermocouple was verified to the calibrated thermometer with R2 = 0.99. The installation of phase change material based on dry ice gel on the wall freezer could maintain the temperature around 1-2oC while the freezer was turned off for 4, 6, and 8 hours. The efficiency of freezer could be increased from 10% to 30% due to using dry ice gel phase change material. The future study should investigate the various types of phase change materials and the new combination of phase change materials.

This study compares the simulation results of a CNC lathe program with the actual production results of a CNC lathe. CNC lathes are used in the manufacturing of precision components for various industrial applications. Simulation of CNC lathe programs can provide an accurate estimate of the production output before the actual production process begins. In this study, we compared dimensional tolerance, geometric accuracy, and surface quality between simulated and actual results. The simulation method used is 2D modeling which involves the calculation of tool trajectories and cutting parameters inputted into the simulation panel. Actual production data was obtained from the measurement of components produced from the CNC lathe. A comparative analysis was conducted to evaluate the extent to which the simulation can predict the actual production results. The results show that, although the simulation can give a good picture, there is still a significant difference between the simulation results and actual production. The findings have practical implications in improving efficiency and accuracy in the planning and production process using CNC lathes.

Perkembangan mobil listrik yang semakin pesat menuntut desain rangka yang ringan, kuat, dan mampu menahan getaran selama pengoperasian. Penelitian ini bertujuan untuk menganalisis karakteristik modal rangka kendaraan listrik menggunakan metode Finite Element Analysis (FEA) pada ANSYS 2024 R1. Analisis modal dilakukan untuk mengetahui frekuensi alami dan bentuk getaran rangka, sehingga dapat dipastikan bahwa struktur tidak mengalami resonansi akibat getaran motor, kondisi jalan yang tidak rata, maupun osilasi sistem penggerak. Model rangka tiga dimensi dirancang menggunakan SolidWorks dan dianalisis dalam kondisi free modal tanpa batasan tumpuan agar respons dinamis rangka dapat tergambar secara realistis. Tiga jenis material dibandingkan, yaitu Structural Steel, Titanium Alloy, dan Epoxy Carbon Composite, yang umum digunakan dalam pengembangan rangka mobil listrik karena karakteristik kekuatan dan efisiensi beratnya. Hasil penelitian menunjukkan bahwa Structural Steel memiliki frekuensi alami tertinggi namun dengan bobot yang lebih besar. Titanium Alloy memberikan keseimbangan antara kekakuan dan pengurangan massa, sedangkan Epoxy Carbon Composite menunjukkan frekuensi lebih rendah tetapi memiliki potensi redaman getaran dan efisiensi massa yang baik. Temuan ini membuktikan bahwa pemilihan material sangat berpengaruh terhadap respons dinamis dan keamanan struktural rangka kendaraan listrik. Penelitian ini merekomendasikan penggunaan material komposit atau kombinasi material sebagai pendekatan optimal dalam pengembangan rangka mobil listrik pada masa mendatang.
