Abstract

Treatment technology of sea water into freshwater is known as desalination. An effective and economical desalination technique is desalination with evaporation. Thisstudy aims to determine the effect of roofing materials on the amount of freshwater produced. The study was conducted using a miniature evaporative tub that had a rooflike shape. Evaporative tubs dimension was 1m x 1m x 0.02m of laminated wood material. 20 liters of brackish water was pumped into the tub. Water in the tub was then closed using a roof designed like a roof made of fiberglass and polycarbonate. Brackish water was left in contact with the sunlight for 24 hours. As a result of heat transfer from sunlight to evaporation tub, brackish water experienced evaporation. The steam moved upward and was captured by the roof wall then condensated resulting in fresh water. The conclusion obtained was a miniature roof of evaporative desalination using fiberglass material obtained 427 ml of fresh water while using polycarbonate material obtained 136 ml fresh water. Keywords: Roof, Desalination, Evaporation.

Abstract

Studi ini mengevaluasi efek berbagai jenis pakan hijauan terhadap konsumsi dan pertambahan bobot badan kelinci Anggora di Kabupaten Langkat, Sumatera Utara. Pengembangan kelinci sebagai alternatif sumber daging menghadapi tantangan psikologis dalam konsumsi dagingnya serta tingginya tingkat kematian ternak. Teknologi pengolahan daging kelinci telah diimplementasikan untuk menghasilkan berbagai produk olahan yang meningkatkan nilai ekonomis. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan berbeda: kangkung, rumput sintrong, rumput bayam-bayaman, dan rumput lapang. Hasil penelitian menunjukkan variasi signifikan dalam konsumsi pakan kelinci antar perlakuan, dengan konsumsi tertinggi tercatat pada kelinci yang diberi rumput lapang (282,14 gr/ekor/hari). Selain itu, terdapat perbedaan yang signifikan dalam pertambahan bobot badan antar perlakuan, dimana kelinci yang menerima rumput bayam-bayaman (11,26 g/ekor/hari) dan rumput sintrong (11,01 g/ekor/hari) mengalami pertambahan bobot badan lebih tinggi dibandingkan dengan kelinci pada perlakuan kangkung (10,99 g/ekor/hari) dan rumput lapang (10,66 g/ekor/hari). Rataan pertambahan bobot badan keseluruhan selama penelitian adalah sebesar 10,98 g/ekor/hari. Pentingnya manajemen pakan yang tepat untuk meningkatkan efisiensi nutrisi dan kesehatan kelinci sangat ditekankan dalam penelitian ini. Strategi ini dapat diterapkan untuk mendukung pengembangan peternakan kelinci sebagai usaha komersial yang berorientasi pasar, serta meningkatkan potensi kelinci sebagai sumber daging yang berkualitas dan dapat diterima oleh berbagai lapisan masyarakat. Studi lebih lanjut disarankan untuk mengeksplorasi faktor-faktor lain yang dapat mempengaruhi produktivitas kelinci, seperti pengelolaan lingkungan dan genetika, guna mendukung pertumbuhan industri kelinci yang berkelanjutan.

Abstract

ABSTRACT Concentration is a key factor in the successful execution of the roll spike technique in sepak takraw, as this movement requires high levels of coordination, precision, and mental control. However, in practice, athletes often exhibit low levels of focus and confidence when performing this technique. This study aims to analyze the effect of imagery training on improving concentration in executing the roll spike among sepak takraw athletes in Mataram. The study employed an experimental approach using a one group pretest-posttest design without a control group. The subjects consisted of nine athletes who received imagery training as the treatment. Data were collected through a roll spike skill test and analyzed using a t-test to compare pretest and posttest results. The findings indicate a significant improvement in concentration following the implementation of imagery training. These results suggest that imagery training is effective in enhancing athletes’ focus and the quality of roll spike execution. Therefore, imagery-based mental training can be considered a strategic approach to improving athletic performance, particularly in complex technical skills in sepak takraw. ABSTRAK Konsentrasi merupakan faktor kunci dalam keberhasilan pelaksanaan teknik roll spike pada permainan sepak takraw, karena gerakan ini menuntut koordinasi, ketepatan, dan kontrol mental yang tinggi. Namun, dalam praktiknya masih ditemukan rendahnya fokus dan kepercayaan diri atlet saat melakukan teknik tersebut. Penelitian ini bertujuan untuk menganalisis pengaruh latihan imagery terhadap peningkatan konsentrasi roll spike pada atlet sepak takraw di Mataram. Penelitian menggunakan pendekatan eksperimen dengan desain one group pretest-posttest tanpa kelompok kontrol. Subjek penelitian berjumlah 9 atlet yang diberikan perlakuan berupa latihan imagery. Pengumpulan data dilakukan melalui tes keterampilan roll spike, kemudian dianalisis menggunakan uji t untuk membandingkan hasil sebelum dan sesudah perlakuan. Hasil analisis menunjukkan adanya peningkatan konsentrasi yang signifikan setelah pemberian latihan imagery. Temuan ini mengindikasikan bahwa latihan imagery efektif dalam membantu atlet meningkatkan fokus perhatian serta kualitas eksekusi teknik roll spike. Dengan demikian, latihan mental berbasis imagery dapat menjadi alternatif strategis dalam mendukung peningkatan performa atlet, khususnya pada keterampilan teknik yang kompleks dalam olahraga sepak takraw.
