    Penyesuaian sosial menjadi hal penting bagi siswa dalam berinteraksi dan berbaur dengan lingkungannya terutama dalam lingkungan sekolah. Untuk melakukan penyesuaian sosial dengan baik siswa memerlukan konsep diri yang positif dan menerima dukungan sosial dari lingkungan sekitarnya. Penelitian ini bertujuan untuk mengetahui hubungan antara konsep diri dan dukungan sosial dengan penyesuaian sosial pada siswa MAN Siak. Subjek penelitian ini adalah siswa kelas 2 dan 3 MAN Siak yang berjumlah 176 siswa. Pengumpulan data menggunakan skala konsep diri, skala dukungan sosial, dan skala penyesuaian sosial. Analisis data menggunakan teknik Multiple Regression dengan bantuan SPSS 16 for windows. Hasil analisis data menunjukkan ada hubungan antara konsep diri dan dukungan sosial dengan penyesuaian sosial siswa, yang terlihat dari nilai F=48.454 dan nilai signifikasi p=0.000. Konsep diri dan dukungan sosial secara bersama-sama dapat menjelaskan tinggi rendahnya penyesuaian sosial sebesar 35,8%. Artinya ada hubungan positif antara konsep diri dan dukungan sosial dengan penyesuaian sosial. Berdasarkan hasil penelitian, penyesuaian sosial dapat berjalan dengan baik jika siswa memiliki konsep diri yang positif dan mendapatkan dukungan sosial dilingkunganya. Kata kunci : Konsep diri, Dukungan sosial, Penyesuaian sosial, Siswa madrasa

    Performance Evaluation of Ammonia Refrigeration Systems in a Texturizing Plant

    This study evaluates the performance of an ammonia refrigeration system used as a cooling medium in a texturizing plant. The analysis was conducted over a 10-day period, focusing on key performance indicators such as compressor work, condenser exhaust heat, refrigeration effect, mass flow rate, Coefficient of Performance (COP), and overall system efficiency. The data revealed that the system performed optimally on Day 5, achieving a peak efficiency of 91%, with compressor work at 304.1 kJ/kg and condenser exhaust heat at 1414.6 kJ/kg. In contrast, the lowest efficiency was recorded on Day 3, at 77%. The refrigeration effect reached its highest value of 491.3 kJ/kg on Day 3, highlighting efficient heat absorption despite lower overall system efficiency. On Day 4, the mass flow rate was 0.001049929 kg/s, with an actual COP of 1.39, while the ideal COP peaked on Day 10 at 1.69, reflecting the system’s theoretical maximum efficiency under optimal conditions. The study emphasizes the critical role of the condenser in the system’s performance. Optimizing the condenser’s operation by controlling temperature, pressure, and flow rates, alongside regular maintenance, significantly impacts system efficiency. The findings suggest that careful monitoring of operational parameters, including compressor work and refrigerant flow, can enhance the overall efficiency and reliability of ammonia refrigeration systems in industrial settings. This research provides practical insights into improving the cooling performance, reducing energy consumption, and ensuring consistent production quality in texturizing plants

    Teknologi, informasi dan komunikasi yang berkembang begitu cepat secara langsung berdampak kompleks pada manusia termasuk di dunia pendidikan. Dunia Pendidikan saat ini turut mengambil bagian dalam memanfaatkan perkembangan teknologi dan informasi guna meningkatkan kualitas Pendidikan di Indonesia khususnya. Sebagai upaya untuk meningkatkan kualitas Pendidikan di Indonesia sudah selayaknya jika dimulai dari pembenahan proses pembelajaran. Hal itu karena, pembelajaran merupakan faktor penting dalam menentukan kualitas pendidikan. Perkembangan teknologi dan informasi berperan dalam perubahan terhadap proses pembelajaran di Indonesia. Jika dahulu sebagian besar pembelajaran di Indonesia menggunakan metode ceramah dimana guru menjadi sumber belajar utama bagi siswa, maka dengan adanya pemanfaatan teknologi dan informasi, siswa diharapkan mulai aktif dalam hal belajar dan sehingga guru hanya berperan sebagi fasilitator saja. Tujuan penelitianiniadalah untuk mengetahui bagaimana pemanfaatan perkembangan teknologi dan informasi dalam dunia pendidikan. Hasil penelitian menunjukan bahwa ternyata perkembangan teknologi, informasi dan komunikasi dapat diintegrasikan dalam proses pembelajaran. Pemanfaatan teknologi, informasi dan komunikasi dapat mendorong kreativitas siswa selama pembelajaran. Selain sebagai media belajar, teknologi, informasi dan komunikasi dapat menjadi alat dan media dalam pendistribusian materi ajar serta memberikan kemudahan dalam melakukan komunikasi belajar. Sehingga secara keseluruhan pemanfaatan teknologi, informasi dan komunikasibermuara pada peningkatan kualitaspendidikan di Indonesia
