Airfoil is a cross section from air plane wings can affect aerodynamic performance to lift force (FL). The lift force generated by airfoil has different values due to several external and internal factors, including angle of attack, flow rate and camber. To find the lift force of airfoils with different cambers and variations angle of attack and then flow rate can use computational fluid dynamics simulation. Computational fluid dynamics is simulation on a computer that can complete systems for fluid, heat transfer and other physical processes. This research using computational fluid dynamics simulation performed by SolidWorks, with NACA airfoil type which has different camber NACA 0012, NACA 4612 and NACA 6612. The angle of attack used in research was 0o, 4o, 8o, 12o, 16o and 20o. Flow rate used in research was 20m/s, 40 m/s, 60 m/s, 80 m/s and 100 m/s. From this research will be the bigger camber can produce a greater force lift. In addition, the greater airfoil flow rate can produce a greater force lift. This research also that the connection between force lift with coefficient lift (CL) is nonlinear quadratic form.

AbstractIn this study, we model the transmission of COVID-19 by considering vaccination and quarantine interventions. The focus of our study is to measure the effect of these two interventions on controlling the spread of COVID-19. We demonstrate the use of the Kermack-McKendrik model as an SIR model for the number of people infected with COVID-19 applied in Jember, Indonesia. The model parameters are estimated using the Levenberg-Marquardt approach and the model equations are solved using the Runge-Kutta 4th-order method. Through the simulation study, we can determine the peak of the spread of COVID-19 cases and obtain several parameters related to vaccination and quarantine interventions that significantly affected the transmission rate of COVID-19. It is found that a faster rate of vaccinations will reduce the rate of transmission of COVID-19. Moreover, COVID-19 can be fully controlled if the infected patients carry out proper quarantine procedures.Keywords: COVID-19; Kermack-McKendrik; Levenberg-Marquardt; quarantine; SIR; vaccination.

Dalam faktanya, Al-Qur’an terlihat fokus terhadap persoalan akal manusia. Akal diibaratkan seperti mata, yang memiliki potensi untuk melihat sesuatu yang berada di sekitarnya, akan tetapi dalam pekerjaannya, mata tidak bisa berproses tanpa adanya cahaya, artinya ia tidak dapat melihat apapun. Apabila cahaya hadir, maka mata bisa melakukan pekerjaannya dengan baik, yaitu melihat sekitar dengan jelas. Oleh karena itu, akal sangat berhubungan dengan wahyu,karea ia hadir untuk menerangi akal dalam memperoleh kebenaran. Hal ini dikarenakan manusia sebagai objek sasaran mutlak untuk memperoleh ilmu dan kebenaran tesebut. Ketika dua hal tersebut telah didapatkan, manusia akan lebih mudah meniti jalan menuju ketaqwaan kepada Allah ‘Azza wa Jalla. Meskipun dalam al-Qur’an akal begitu dimuliakan, akan tetapi tidak menyerahkan segala sesuatu kepada akal, bahkan Al-Qur’an membatasi radius akal sesuai dengan kemampuannya, karena akal pun memiliki jangkauan yang terbatas dan tidak akan mungkin bisa menjangkau akar dari segala sesuatu. Maka dari itu, Islam menundukkan akal terhadap Wahyu dan Sunnah Nabi saw, artinya di dalam segala hal wahyu dan sunnah harus di dahulukan. Dalam tulisan ini, peneliti menggunakan metode library research dengan pendekatan kualitatif. Pendekatan ini dilakukan dengan maksud menitikberatkan pada pembahasan akal perspektif al-Qur’an, baik dari fungsi dan kedudukannya serta hubungannya dengan wahyu dengan bersumber pada kajian literatur seperti kitab tafsir, hadits, artikel jurnal, dan literature pendukung lainnya.

Facebook sering dimanfaatkan penggunanya untuk mengunggah persoalan mengenai pelayanan publik. Maraknya unggahan berisikan informasi semacam itu, adalah potret kualitas pelayanan publik di negeri ini. Kenyataan itu bisa jadi adalah indikator rendahnya kualitas pelayanan publik di Indonesia. Parahnya, yang mengalami keadaan itu lebih banyak dari kalangan masyarakat yang tidak beruntung secara ekonomi. Besarnya tuntutan masyarakat terhadap kualitas profesionalisme penyelenggara pelayan publik, dapat ditengarai sebagai pertanda berkembangnya pemahaman masyarakat terhadap hak-haknya sebagai warga negara. Hal itu bisa berdampak pada perbaikan kinerja birokrasi dalam rangka memberikan pelayanan. Sebagaimana termaktub dalam Undang-Undang, nomor 25 Tahun 2009, tentang Pelayanan Publik. Pelayanan publik adalah kegiatan dalam rangka pemenuhan kebutuhan pelayanan bagi setiap warga negara dan penduduk atas barang, jasa, dan/atau pelayanan administratif yang disediakan oleh penyelenggara pelayanan publik. Unggahan di Facebook seputar masalah pelayanan publik menjadi fokus persoalan dalam penelitian ini. Penelitian ini juga bertujuan untuk mendeskripsikan dan menganalisis motif yang melatari pengguna Facebook untuk mengunggah keluhan tentang penyelenggaraan pelayanan publik. Penelitian ini dilakukan dengan pendekatan kualitatif. Untuk menghimpun data, peneliti melakukan wawancara kepada sejumlah pengguna Facebook, selain mengamati teks-teks yang diunggah di akun Facebook terkait isu pelayanan publik. Dari hasil wawancara terhadap tiga pengguna FB yang mengunggah keluhan atas pelayanan publik, ketiga informan memiliki motif yang sama dalam mengunggah postingan. Yaitu menarik perhatian publik dan berharap mendapatkan respon dari instansi yang dituju. Menurut salah satu informan, postingan tersebut diharapkan dapat membangun kesadaran publik atas hak layanan publik yang seharusnya diterima. Facebook is often used by users to upload issues regarding public services. The rise of uploads containing such information is a portrait of the quality of public services in this country. That fact could be an indicator of the low quality of public services in Indonesia. Worse, who experienced the situation more than the people who are economically disadvantaged. The large demand of the community for the professionalism of the quality of public service providers can be seen as a sign of the development of public understanding of their rights as citizens. That can have an impact on improving the performance of the bureaucracy in order to provide services. As stipulated in the Law, number 25 of 2009, concerning Public Services. Public services are activities in the context of meeting the service needs of every citizen and population of goods, services, and / or administrative services provided by the public service providers. Uploads on Facebook about the issue of public services are the focus of the problem in this study. This study also aims to describe and analyze the motives behind Facebook users to upload complaints about the administration of public services. This research was conducted with a qualitative approach. To collect data, researchers conducted interviews with a number of Facebook users, in addition to observing texts uploaded on Facebook accounts related to public service issues. From the results of interviews with three FB users who uploaded complaints about public services, all three informants had the same motive in uploading posts. That is attracting public attention and hoping to get a response from the intended agency. According to one informant, the post is expected to be able to build public awareness of the rights of public services that should be received.
