CFD Simulation and Wind Tunnel Test of NACA 4412 Airfoil Wing Section at Different Angles of Attack

Airfoil can be defined as a body shape so that lift can be generated as fluid flow through it. The study of thin aerofoil by changes in a few characteristic such as different angle of attack, α would provide changes in lift, drag, and pitching moment coefficients. In order to identify the changes, Computational Fluid Dynamic (CFD) simulation has been applied by using ANSYS, FLUENT and GAMBIT software and followed by experiments conducted in a low speed wind tunnel to obtain measurement results. Shape of the body is important in achieving the desired result. NACA 4412 airfoil, which is high lift wing type, was chosen as the airfoil shapes in the present work. It was identified along the entire project. The aerodynamics characteristics of this airfoil have been shown by the plot of the coefficient graph lift and drag. This results obtained by both CFD and wind tunnel test. Although there is a little differences between results of these two methods, but, the general trend is the same. The results were compared with previous experimental results and they are in good agreement. It can be concluded that Reynolds Number values are affecting the characteristic of the airfoil and this is the reason for the small differences of recent results from others. However, a few recommendations have been outlined for further investigation

KEKOSONGAN JABATAN WAKIL BUPATI ACEH SELATAN PERIODE 2018-2023 MENURUT UNDANG-UNDANG PEMERINTAHAN ACEH

Penelitian ini bertujuan guna mengetahui mengapa Bupati Aceh Selatan dan partai pengusung belum mengusulkan calon Wakil Bupati periode 2018-2023 untuk dipilih dalam rapat Paripurna DPRK/DPRA dan bagaimana ketentuan Undang-Undang Nomor 11 Tahun 2006 terhadap kekosongan Jabatan Wakil Kepala Daerah. Penelitian ini menggunakan metode kualitatif dengan pendekatan yuridis empiris. Teknik pengumpulan data dengan wawancara, kemudian dianalisis dengan deskriptif-analisis. Hasil penelitian menunjukkan 2 (dua) faktor penghambat proses pengusulan Wabup Aceh Selatan yaitu faktor politis terhadap keadaan pandemi Covid-19 serta miskomunikasi antara partai pengusung dan Bupati Aceh Selatan dalam penentuan nama calon yang ingin diusulkan. Kemudian faktor lemahnya aturan undang-undang (yuridis) mengenai pengisian Wakil Kepala Daerah sehingga terjadi kelalaian dalam proses pengusulan. Pada akhirnya, proses untuk pengisian kekosongan jabatan Wakil Bupati Aceh Selatan tidak terselesaikan. Kekosongan jabatan Wakil Bupati Aceh Selatan menyalahi Pasal 54 ayat (3) Undang-Undang Nomor 11 Tahun 2006 tentang Pemerintahan Aceh (UUPA).&nbsp

Dimensi amalan etika profesion

A crisis of confidence in the society is partly due to the reason that the society increasingly feels that their interests are not served by the professions. The situation if allowed to continue will not only adversely affect the professions, but will also destabilize the society. This study aims to identify the dimensions of ethical practices among the teaching profession at a public institute of higher learning. Quantitative data were collected from 147 lecturers to determine the basic concept of ethics, while qualitative data were collected through interviews to understand ethical practices. Results from the quantitative study indicate that the respondents opined that ethics can be learned and attitudes were the determinants of ethical practices. Ethical practices were based on spiritual intelligence developed through education at home and the workplace. Qualitative findings showed that the dimensions of ethical practices are founded on religion and values, followed by epistemological foundations and competencies, and practiced through operational and contextual fundamentals. These three dimensions are interrelated and influence each other. Dilemmas on ethical decision making are addressed through strong principles and practiced at each of these dimensions. The implications are directed toward formal and non-formal training of lecturers on spiritual aspects throughout the career of the lecturers

PENEGAKAN HUKUM JINAYAT BAGI NON MUSLIM DI ACEH

Law enforcement against non-Muslims who commit violations of jinayat law tends to use the penalties stipulated in the Qanun Hukum Jinayat compared to other criminal statutory provisions. This phenomenon is interesting to study because non-Muslims who commit criminal acts (Jarimah) are given the choice of choosing to use Qanun or other Criminal Law which is regulated outside the Qanun. This study aims to analyze how the enforcement of jinayat law against Jarimah is carried out by non-Muslims, why non-Muslims are more likely to choose jinayat law than the provisions of other criminal laws and regulations outside of the Qanun and which penalties are imposed more dominantly by syar'iyah court judges. The author uses the empirical juridical research method with the aim of describing concrete facts about jinayat law enforcement for non-Muslims. The primary legal materials used are Qanun Hukum Jinayat Qanun Hukum Procedural Jinayat. Secondary legal materials, namely through books, journals and research results. Primary data was obtained through interviews with non-Muslims who had been sentenced according to qanun, judges and Wilayatuh Hisbah (WH). The results showed that enforcement of jinayat law for non-Muslims must first seek approval from the suspect to use qanuns or criminal laws other than qanuns. Then the investigator takes action according to the choice set by the suspect. Non-Muslims tend to choose qanuns due to several factors: first, the punishment is more instantaneous than the KUHP which carries a prison sentence. Second, the people who witnessed the execution of the caning were not all citizens who knew him. The more dominant punishments handed down by judges were ta'zir flogging and actions in the form of revoking their business license
