Abstract

Pada observasi awal  yang telah dilakukan  beberapa sekolah SMA di kota Jayapura dan kabupaten Jayapura ditemui kurangnya motivasi peserta didik terhadap Pelajaran fisika hal  berakibat pada hasil belajar fisika yang masih rendah.  Dari pengamatan ditemui bahwa Sebagian besar guru lebih memilih metode ceramah , hal ini hal ini dikarenakan lebih mudah dilakukan dibandingkan dengan metode pembelajaran yang melibatkan peserta untuk lebih aktif. Kemudian ditemukan  dalam proses pembelajaran guru hanya mengajar teori tanpa memberikan praktik atau contoh kasus yang ada disekitar siswa. Sehingga banyak siswa beraggapan bahwa  pembelajaran fisika  hanya berkutat pada  teori-teori yang tidak bermanfaat  pada kehidupannya nyata. Salah satu cara untuk mengatasi adanya praktikum di sekolah dengan keterbatasan alat yaitu mengunakan virtual laboratory.  Salah satu virtual laboratory yang telah tim kami kembangkan berbasis VBA excel. Di mana hampir semua perangkat baik kompoter maupun labtop yang ada sekolah baik yang dimiliki  guru secara pribadi maupun fasilitas komputer yang disediakan sekolah. Salah satu pendekatan pengajaran yang efektif untuk meningkatkan motivasi siswa adalah Pembelajaran Berbasis Masalah (PBL). Peserta didik didorong untuk melatih pemikiran kritis melalui metode ini.. Penelitian ini dilakukan di SMA Pembangunan V Yapis Kota Jayapura untuk mengamati dampak PBL yang diintegrasikan dengan media VBA Excel terhadap motivasi belajar siswa. Studi ini menggunakan metode deskriptif kualitatif. Analisis data dilakukan secara komprehensif, mencakup data kuantitatif dan kualitatif. Hasil analisis kuantitatif sederhana menunjukkan bahwa 80% siswa memiliki motivasi belajar tinggi. Temuan ini didukung oleh hasil regresi yang menunjukkan nilai signifikansi kurang dari 0,05, mengindikasikan pengaruh signifikan model pembelajaran PBL terhadap motivasi belajar siswa.

Abstract

The controversy about the al-Maqâshid al-Dlarûriyyah al-Khams hierarchy has an effect on the understanding of the Maqâshid al-Syarî'ah hierarchy in the MUI version of the Fiqh Pandemic, especially the fatwa on congregational and Friday prayers in mosques. In dzahir, the fatwa prioritizes hifdz al-nafs over hifdz al-dîn, while the majority of scholars are of the opinion that hifdz al-dîn occupies the highest hierarchy. This research aims to reveal a moderate understanding of the Maqâshid al-Syarî'ah hierarchy in Fiqh Pandemic from the perspective of Fiqh al-Awlawiyyât. This research is qualitative by using Istiqrâ̕, Muqâranah and Tawtsîqî methods. The results of this study are: first, the al-Tarjîh rule used by the theocentric group allows for a middle way to bring together views between theocentric and anthropocentric groups in determining the Maqâshid al-Syarî'ah hierarchy; second, Fiqh al-Awlawiyyât is a comprehensive instrument to determine the Maqâshid al-Syarî'ah hierarchy in Pandemic Fiqh, because it accommodates the rules of al-Tarjîh, Fiqh al-Muwâzanah and Fiqh al-Taisîr wa Raf' al-Haraj, even in harmony with Fiqh al-̒Adzâr through Qiyâs Awlawî; third, Fiqh al-Awlawiyyât becomes a middle ground for the controversy between theocentric and anthropocentric groups in the context of the Maqâshid al-Syarîʻah hierarchy. In conclusion, the Maqâshid al-Syarî'ah hierarchy in Pandemic Fiqh with the priority of hifdz al-nafs over hifdz al-dîn is set moderately by using Fiqh al-Awlawiyyât.Kontroversi tentang hirarki al-maqāshid al-dlarūriyyah al-khams berpengaruh pada pemahaman hirarki Maqāshid al-Syarī’ah dalam Fikih Pandemi versi MUI, khususnya fatwa tentang shalat Jama’ah dan Jum'at di masjid. Secara dzahir, fatwa tersebut mendahulukan hifdz al-nafs atas hifdz al-dīn, sedangkan Jumhūr ulama ber­pendapat bahwa hifdz al-dīn menempati hirarki tertinggi. Kajian ini bertujuan untuk meng­ungkap pemahaman moderat tentang hirarki Maqāshid al-Syarī’ah dalam Fikih Pandemi perspektif Fiqh al-Awlawiyyāt. Penelitian ini bersifat kualitatif dengan menggunakan metode Istiqrâ̕, Muqāranah dan Tawtsīqī. Hasil penelitian ini adalah: pertama, kaidah al-Tarjīh yang digunakan kelompok teosentris memungkinkan adanya jalan tengah mempertemukan pandangan antara kelompok teosentris dan antropo­sen­tris dalam penentuan hirarki maqāshid al-syarī’ah; kedua, Fiqh al-Awlawiyyāt merupakan instrumen komprehensif untuk menentukan hirarki Maqāshid al-Syarī’ah dalam Fikih Pandemi, karena ia mengakomodir kaidah al-Tarjīh, Fiqh al-Muwāzanah dan Fiqh al-Taisīr wa Raf' al-Haraj, bahkan selaras dengan Fiqh al-A’dzār melalui Qiyās Awlawī; ketiga, Fiqh al-Awlawiyyāt menjadi jalan tengah bagi kontroversi antara kelompok teosentris dan antroposentris dalam konteks hirarki Maqāshid al-Syarīʻah. Kesimpulannya, hirarki Maqāshid al-Syarī’ah dalam Fikih Pandemi dengan prioritas hifdz al-nafs daripada hifdz al-dīn ditetapkan secara moderat dengan menggunakan Fiqh al-Awlawiyyāt.

Abstract

The abuse of Narcotics, Psychotropics, and Addictive Substances (NAPZA) has become a serious issue among adolescents, including junior high school students. A lack of understanding and low awareness of the dangers of NAPZA can increase the risk of misuse at an early age. This community service activity aimed to enhance the knowledge and awareness of students at SMP Negeri 10 Kendari regarding the dangers of NAPZA and strategies for its prevention. The method used was an educational intervention through interactive counseling sessions, including discussions and the distribution of educational materials. Evaluation results showed an improvement in students' understanding of the types of NAPZA, the consequences of misuse, and prevention efforts. This activity demonstrates that appropriate and communicative education can serve as an effective preventive measure to reduce the potential for NAPZA abuse among students.

Abstract

The increasing use of fossil-based fuels causes an imbalance between energy demand and the availability of that energy. Therefore, the use of rice husk biomass as alternative energy was implemented through the use of rice husk furnaces. This research aims to optimize the efficiency of a small industrial-scale husk furnace by varying the oxygen flow valve holes and the mass of the heated water. The test on the husk furnace was carried out using the Water Boiling Test (WBT) method with the following test parameters: combustion time, FCR, input power, output power, power loss, radiant energy, and thermal conductivity of the pan and chimney of the husk furnace. Tests were carried out on four variations of the oxygen flow valve holes (horizontal: 18 x 36 cm2 and 27 x 36 cm2, vertical: 27 x 24 cm2 and 27 x 12 cm2) and three variations in the mass of heated water (6 kg, 12 kg, and 18 kg). The highest efficiency of the husk furnace was obtained at 18 kg of water, and based on each test parameter, the performance of the husk furnace was most optimal at the horizontal valve hole measuring 27 x 36 cm2 with an average efficiency of 17.32%.

Abstract

Indonesia has an abundant amount of industry. Production in large, medium, and small industries still uses gas and oil as fuel sources. The fuel sources used still come from non-renewable energy. There is a need for alternative use of renewable energy to reduce the use of non-renewable energy. One solution is the use of rice husk biomass as a fuel source. Rice husk is still often considered as waste despite its many utilizations. The utilization of rice husk waste must be improved to increase its beneficial value. Rice husk waste can be utilized as a fuel source in a husk furnace. A husk furnace is a cooking device in which the fuel (rice husk) is burned using direct combustion. This research aims to optimize the efficiency of the husk furnace by varying the size of the oxygen flow valve hole and the mass of water being heated. Tests were conducted on four variations of oxygen flow valve hole size, namely, 36x27 cm2, 36x34 cm2, 43x34 cm2, and 50x34 cm2, and two variations of water mass (6 and 18 kg). The research was conducted by heating water using the Water Boiling Test method with test parameters: heating time, fuel consumption rate, energy in, energy out, heat efficiency, heat transfer rate, and ash and charcoal yield. The significant efficiency value can be used as a reference for small-scale industrial rice husk furnaces. The most significant efficiency in the study was 54.99%, achieved by a 43x34 cm2 valve hole for heating 18 kg of water. Based on the most effective efficiency value gained, the expansion of the oxygen flow valve hole is sufficient to be used as a test parameter to test the optimization of small industrial-scale husk furnaces.
