Abstract

Telah dilakukan penelitian tentang Simulasi Monte Carlo untuk Model Ising 2D pada Kisi Bujur Sangkar dengan Interaksi Nearest Neighbor and Next NN menggunakan Algoritma Metropolis. Simulasi ini bertujuan untuk menunjukan proses transisi fase dari material feromagnetik menjadi paramagnetik. Model ini dideskripsikan sebagai sistem spin dengan panjang kisi . Hasil simulasi menunjukkan bahwa spin akan semakin acak saat terjadi kenaikan temperatur. Pada magnetisasi maksimum untuk material ferromagnetik, temperatur dan energi berada pada keadaan rendah. Magnetisasi menurun secara drastis pada temperatur dan energi tertentu, kemudian hilang karena material telah bersifat paramagnetik. Hasil ini menunjukkan bahwa magnetisasi bergantung pada temperatur dan energi material.

Abstract

Purpose of this research to determine the effect of mass of source on thickness of thin film, with using the vacuum thermal evaporation. The metal used is Ag with a purity of 99,99% as a source of evaporated metal and using glass preparations as a substrate on which metal is deposited. By using three types of characterization such as FPP, SEM and EDS, the research results were obtained accurately. Based on  these characterizations, the results obtained a significant relationship between mass of source and thickness of thin film, increasing the mass of the source will increase the thickness of thin film. This result can be used as a reference in producing thin films with specific of thickness.

Abstract

Pengelolaan emisi gas buang dari insinerator menjadi isu penting dalam upaya mitigasi pencemaran udara dan perlindungan lingkungan. Penelitian ini bertujuan untuk mengkaji pemanfaatan cangkang kemiri (Aleurites moluccana) sebagai bahan dasar karbon aktif dalam upaya mengurangi emisi gas karbon monoksida (CO) pada insinerator. Karbon aktif yang dihasilkan melalui proses karbonisasi dan aktivasi kimia menggunakan larutan NaOH diuji berdasarkan parameter kualitas sesuai Standar Nasional Indonesia (SNI 06-3730-1995), yaitu kadar air, kadar abu, dan daya serap iod. Sampel karbon aktif yang diperoleh menunjukkan kualitas baik dengan kadar air sebesar 4,09%, kadar abu 9,01%, dan daya serap iod sebesar 837,738 mg/g. Selanjutnya, karbon aktif diaplikasikan sebagai media adsorpsi pada cerobong insinerator. Hasil pengujian menunjukkan adanya penurunan kadar gas CO secara signifikan dari 182 ppm menjadi 4,8 ppm pada menit ke-25 pembakaran, dengan efisiensi adsorpsi berkisar antara 23,4% hingga 96,5%. Penurunan kadar gas CO juga seiring dengan peningkatan suhu ruang bakar yang mendukung pembakaran lebih sempurna. Dengan demikian, karbon aktif dari cangkang kemiri terbukti efektif sebagai media adsorpsi emisi gas CO dan berpotensi diterapkan dalam pengelolaan emisi gas buang insinerator secara ramah lingkungan.

Abstract

This study aims to analyze the meaning of traffic colors as nonverbal communication for motorcyclists in Bone Regency. The approach used is descriptive qualitative with a semiotic method, namely studying signs and how these signs produce meaning in the communication process. Data were obtained through in-depth interviews with two motorcyclists in Bone Regency. The results of the study indicate that the meaning of traffic light colors for each motorcyclist in Bone Regency with the aim of the study to reveal the level of understanding, attitudes, and behavior of drivers in responding to nonverbal messages conveyed by traffic lights, this study emphasizes that traffic lights are not just physical devices, but a sign system whose meaning must be understood and interpreted correctly by the community. Non-compliance with this sign indicates a shift or difference in interpretation in society, which can endanger mutual safety.

Abstract

Dating relationships as a form of intimate personal relationships do not always go as expected. In fact, many cases show that these relationships can lead to discomfort and forms of violence, such as physical, psychological, sexual and financial abuse. This phenomenon has become one of the most discussed social issues, especially on social media. The Instagram account @indonesiatanpapacaran is present as a response to this issue, by voicing an invitation to abandon the practice of dating through moral and religious narratives. The existence of this account has led to various responses from the public, including students as a group of active social media users. This research aims to find out how students perceive the existence of the @indonesiatanpaparan account in the digital space. This research uses a descriptive qualitative approach with in-depth interview techniques and observation as data collection methods. The results showed that students gave diverse responses to the account, reflecting different attitudes, experiences, and perspectives in addressing the dating issues raised. This diversity also confirms that social media is a dynamic space that allows the formation of public opinion on complex social issues.
