Abstract

Diketahui bahwa masyarakat Jakarta menghabiskan biaya sebanyak 38,5 trilyun rupiah untuk kesehatan. Nilai ini cukup tinggi dibandingkan dengan APBN 2016 untuk kesehatan yang mencapai sekitar 67 trilyun rupiah. Enam puluh persen dari penyakit di Jakarta adalah penyakit pernapasan. Untuk kasus ruang gubernur Jakarta pada tahun 2005, diketahui bahwa jumlah partikel di kamar gubernur sekitar 45000 partikel per sentimeter kubik. Ada kemungkinan besar bahwa jumlah ini berhubungan erat dengan kualitas udara yang mengakibatkan gubernur mengalami gangguan pernafasan. Kualitas udara dipengaruhi oleh sirkulasi udara. Jadi, penting untuk merancang sebuah ruangan yang memiliki sirkulasi yang tepat dan memiliki kenyamanan termal. Sebuah model ruang kerja untuk kepala atau ketua telah dipilih sesuai dengan standar. Simulasi computational fluid dynamics (CFD) telah dilakukan untuk menentukan suhu udara masuk sehingga suhu di sekitar tempat pertemuan berada dalam keategori nyaman secara termal. Dari hasil simulasi diketahui bahwa kenyamanan termal tercapai ketika inlet suhu udara sekitar 19oC.

Abstract

Energy is all around us in a very clear shape and utilization. Along with the changing times, the energy is being intensively investigated with the intention to do enhancement to optimize an effective and efficient energy source. Light Emiting Diode (LED), which is one of the electronic component, is not foreign in human life. LEDs are now widely used, such as in children's toys, traffic signs, the indicator light for the electronic equipment industry as well as photography. SMD 3528 LED strip light is a type of LED that is most widely used today. In addition to its relatively small dimensions is also due to the low electrical power consumption. In the world of photography, lighting sources is absolute existence. This study was conducted to determine the characteristics of LED Strip lights SMD 3528 with passive cooling for photographic purposes. From the experimental results, it was obtained the greater input power of is given, the value of the points that were tested was greater. Among other things, LED temperature, the temperature of the middle heat sink, the heat-sink and the outside air (ambient) and the resulting brightness. Material and cross-sectional area and shape of the heat sink greatly affected the absorption and release of heat that occurs on passive cooling.

Abstract

The flow of fluid through the pipe creates fluid friction with pipe walls causing pressure drop and fluid flow velocity affecting the use of energy to drain it. Pressure drop can be affected by several factors such as friction or friction factor, pipe length, pipe diameter and fluid velocity. In this research, it will analyze pressure drop on piping system based on friction, fluid flow characteristics, and fluid velocity. The analysis was done by using two methods, namely experimental method and empirical calculation method. The stages of this study consist of problem analysis, literature study, calibration, data retrieval, empirical data processing and experiments, validation, analysis of results and conclusions. Based on the results of empirical and experimental research, the lowest pressure drop in the experiment and empirical was the 12 LPM discharge copper pipe and the water coolant ratio is 0: 100. This means that the best material pipes used were copper pipes rather than steel and galvanized pipes. The results of the tests and experiments have been tested for validation. The validation value of empirical and experimental data measurement is 91%.

Abstract

The Compilation of Islamic Law is the first codification of Islamic law in Indonesia which is used as a legal guide for Religious Court Judges to decide cases related to marriage, endowments and inheritance. However, is this compilation of Islamic law considered binding law or is it just a guide for judges? Therefore, the author intends to research the position of the Compilation of Islamic Law in family law politics in Indonesia using qualitative research methods in the form of literature studies sourced from books, laws, journal articles and other sources that are appropriate to the material studied. And the research results show that the position of this Compilation of Islamic Law in the Hierarchy of National Legislation until now is still in the form of Presidential Instruction Number 1 of 1991. Meanwhile, the Presidential Instruction is only limited to providing direction, guiding, mentoring, in terms of carrying out tasks and work. So if you look at article 7 of Law Number 12 of 2011, this Presidential Instruction does not include the Type, Hierarchy and Content of statutory regulations. Therefore, the position of the Compilation of Islamic Law in family law politics in Indonesia is still weak. However, what is meant by weak here is not weak in terms of the content of the Compilation of Islamic Law but only its position. However, this Compilation of Islamic Law is really needed and very important for the Muslim community, therefore the author hopes that its position can be improved so that it becomes a law that is not just a guideline for judges, but a law that Muslims can follow. in Indonesia.

Abstract

التربية هي جهد واعٍ يتم تنظيمه لاكتشاف وتنمية قدرات الإنسان بحيث يحدث تحول، سواء في مجال المعرفة أو السلوك أو القيم التي تم تحديدها. تختلف التربية الإسلامية عن غيرها من أنواع التربية لأن معيارها لا يقتصر على الحكم بالصواب والخطأ. يجب أن تستند التربية الإسلامية إلى القرآن الكريم الذي يعتبر المصدر الأساسي للشريعة في الإسلام. بالإضافة إلى ذلك، يجب أن تستند التربية الإسلامية أيضًا إلى الحديث النبوي الشريف. الغاية النهائية هي إنتاج إنسان يمتلك مهارات في جوانب التعليم متوافقة مع هذين المصدرين الرئيسيين. لذا، فإن الهدف النهائي لا يقتصر فقط على تغيير السلوك أو التفكير، بل يجب أن يتماشى كل ذلك مع توجيهات القرآن الكريم والحديث الشريف. يمكن أن تحقق الأنشطة التعليمية والتربوية النجاح إذا دعمتها مكونات جيدة. ومن بين هذه المكونات الرئيسية المنهجية، وهي الطريقة التي يجب أن يتبعها المعلم في تعليم طلابه لتحقيق الأهداف التي تتماشى مع توجيهات القرآن الكريم والسنة النبوية. استخدام الطريقة بشكل صحيح سيحدد بشكل كبير نتيجة عملية التعليم والتدريس. لذلك، يجب على المربي أن يكون ماهرًا في اختيار واستخدام الطريقة بحيث تكون مناسبة للمادة والمواد الدراسية. بالإضافة إلى ذلك، يجب على المربي مراعاة بعض المبادئ في استخدام الطريقة، حتى تؤدي طريقة التدريس إلى نجاح العملية التعليمية.

Abstract

This research is motivated by the fact that there is still a lot of unproductive agricultural land in West Java, even though the agricultural sector contributes a lot to the community's economy. There needs to be an effort to involve various components of society, especially Islamic boarding schools, in increasing the productivity of agricultural land through cooperation using the muzâra'ah system involving many parties to improve the welfare of farmers and Islamic boarding schools. The aim of this research is to analyze and discover land management practices, cooperation models, and the impact of agricultural cooperation on the welfare of farmers in West Java. This research is field research using a qualitative approach. The research results show that, First, agricultural land management practices in West Java are collaborated with various parties, both internal Islamic boarding schools such as students, teachers and administrators as well as with the surrounding farming community. The two Islamic boarding school agricultural collaborations with the muzâra'ah system in West Java were expanded in scope, not just farmers and landowners, but there were elements of academics, government, the business world, financial institutions, markets and non-governmental organizations. Islamic boarding schools innovate agricultural cooperation with the quintuple helix model using multi contracts, namely connecting these parties to optimize the agricultural business being collaborated. Islamic boarding schools also build aspects of farmers' spirituality through guidance on the application of religious values in agricultural cooperation. Third, Islamic boarding school agricultural cooperation is able to absorb agricultural labor, so that farmers are able to improve their economy, have permanent jobs and increase their religious understanding and practice.
