Oryzias sarasinorum atau disebut rono oleh masyarakat setempat merupakan ikan endemik di danau Lindu, Sulawesi Tengah, Indonesia. Ikan ini terancam punah di habitatnya, sehingga domestikasi (pemeliharaan dan pengembangbiakan) di lingkungan terkontrol mendesak dilakukan sebagai salah satu upaya konservasi. Salah satu dasar domestikasi ikan liar adalah pengetahuan terhadap habitat mereka. Tahap selajutnya yaitu membawa ikan tersebut dari habitat aslinya ke lingkungan terkontrol. Masalah pengangkutan ikan dengan sistem tertutup yaitu kematian, sehingga perlu penggunaan zeolit, arang aktif dan garam dalam air media pengangkutan. Perlakuan yaitu penambahan 20 g zeolit + 10 g arang aktif pada media air tanpa garam (A), 1 g L-1 garam (B), 2 g L-1 (C) dan tanpa zeolit, arang aktif dan garam (D). Tujuan penelitian yaitu menganalisis beberapa karekteristik habitat, sintasan selama pengangkutan dan pemeliharaan pascapengangkutan. Habitat ikan rono di pesisir Lovu danau Lindu memiliki dasar landai, substrat pasir kasar, warna air cokelat-teh, terdapat serasah, tanaman air Phragmites karka. Juwana dan larva ikan rono berenang bergerombol di sekitar tanaman dala yang terendam air. Ikan rono muda dan dewasa terlihat makan di atas substrat dasar perairan. Spesies ikan lain yang ditemukan di habitat ini yaitu nila Oreochromis sp., sepat Trichopodus sp., serta Gambusia affinis. Penambahan zeolit dan arang aktif selama pengangkutan dapat meningkatkan sintasan ikan rono dibandingkan tanpa penambahan. Perlakuan A menghasilkan sintasan yang lebih tinggi 62,50% dibandingkan B dan 37,50% dibandingkan C selama pemeliharaan pascapengangkutan pada penelitian ini.
Pertumbuhan ikan nila jantan cenderung lebih cepat dibandingkan dengan ikan nila betina. Salah satu upaya untuk mempercepat pertumbuhan ikan nila yaitu dengan sex reversal. Sex reversal melalui maskulinisasi memungkinkan ikan betina berdiferensiasi menjadi ikan jantan. Air kelapa mengandung kalium (312 mg/100 g) berfungsi sebagai alternatif bahan alami pengganti hormon sintetis 17α- Methyltestosterone. Tujuan penelitian ini untuk mengetahui pengaruh konsentrasi air kelapa yang berbeda terhadap persentase kelamin jantan ikan nila yang dihasilkan melalui perendaman. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan yaitu Perlakuan A (kontrol), B (konsentrasi air kelapa 25%), C (konsentrasi air kelapa 35%) dan D (konsentrasi air kelapa 45%). Data dianalisis ragam (ANOVA) pada taraf kepercayaan 95% dengan uji lanjut Duncan. Hasil penelitian menunjukkan perendaman larva ikan nila dalam air kelapa berpengaruh nyata (α<0,05) terhadap persentase kelamin jantan denga persentase tertinggi pada konsentrasi 35% (86,87%).
This study investigates the English grammar learning strategy used among high, middle, and low achievers’ students in Indonesia. The aim is to reveal which types of strategies that high, middle, and low achievers’ students applied most while learning English grammar and to check whether or not there is difference grammar learning strategy used by high, middle, and low achievers’ students. A lot of researchers have concentrated their interest on the grammar learning strategy area, including in Indonesia, however, it was not seen much or still found limited references to check the grammar learning strategy among high, middle, and low achievers’ students. Besides, the grammar learning strategy instruments of other Indonesian researchers are complexly varied. This study is focused on finding the strategies that high, middle, and low achievers’ students used through Pawlak’s Grammar Learning Strategy Inventory or GLSI (2018) with 100 participants (high vs middle vs low achievers’ students) involved. The results showed that there are significant differences between the frequent use of grammar learning strategies between low, middle, and high achievers' students. Social strategies are the most frequently used grammar learning strategies by low and middle achievers’ students, while metacognitive strategies are the strategies most frequently used by high-achieving students in Indonesia.
PPsychologycal well-being affects mental health, social functioning, interpersonal relationships, health, and adaptability. There are several factors that influence psychologycal well-being, such as meaning, purpose in life, and religiosity. The purpose of this study was to determine the relationship between the meaningfulness of life and the regularity of praying with psychologycal well-being in the 2016 class year students at the Faculty of Usuluddin and Religious Studies of UIN Raden Intan Lampung. The hypothesis proposed in this study is that there is a relationship between the meaningfulness of life and the regularity of praying with psychologycal well-being in students. The subjects in this study were students in 2016 at the Faculty of Islamic Studies and Religious Studies of UIN Raden Intan Lampung totaling 70 people taken by propotionate random sampling technique. Data collection methods in this study used three psychological scales namely the psychological well-being scale with 33 items (α = 0.889), the scale of meaningfulness of life with 25 items (α = 0.843) and the regular scale for praying with 49 items (α = 0.958). The data that has been collected is then analyzed using multiple regression analysis techniques assisted by the SPSS 21.0 for Windows program. The results showed that Rx1.2y = 0.530 with a value of F = 13.082 with p = 0.000 (p <0.01) which means the hypothesis is accepted that there is a significant positive relationship between the meaningfulness of life and the regularity of prayer with psychologycal well-being in students with R2 = 0.281. The ability of life and regular prayers contributed 28.1% to psychologycal well-being. The second result with rx1y = 0.302 with p = 0.011 (p <0.05) which showed a significant positive relationship between meaningfulness of life with psychologycal well-being in the 2016 class year students at the Faculty of Usuluddin and Religious Studies of UIN Raden Intan Lampung. The third result with rx2y = 0.518 with p = 0,000 (p <0.05) which shows a significant positive relationship between the regularity of prayer and psychologycal well-being in students.
AbstrakGangguan kesehatan pada pekerja dapat disebabkan oleh faktor yang berhubungan dengan pekerjaan maupun yang tidak berhubungan dengan pekerjaan. Terdapat pencapaian Kesehatan Kerja yaitu dalam penerapan ergonomi di tempat kerja dengan tujuan untuk meningkatkan kesejahteraan fisik dan mental. Postur kerja merupakan salah satu yang harus diperhatikan dalam ilmu ergonomi.
