Kecelakaan PLTN di Fukushima Dai-ichi, Jepang, pada tahun 2011 telah menunjukkan kegagalan sistem pendingin aktif (pompa) untuk mendinginkan reaktor, yang memicu kajian terkait penerapan sistem pendingin pasif (tanpa pompa) untuk pengembangan manajemen keselamatan di PLTN. Kajian tentang laju aliran sirkulasi alami sebagai dasar sistem pendingin pasif telah dilakukan sejak tahun 2011 di PRTRKKN dengan menggunakan fasilitas eksperimental skala besar yang disebut uji loop FASSIP-02. Fasilitas ini memiliki sistem penukar panas tipe U di tangki pendinginnya, yang merupakan bagian penting dari proses pembuangan ke lingkungan. Dengan demikian, kajian ini bertujuan untuk menganalisis perubahan energi yang terjadi pada penukar panas selama kondisi tunak. Kajian dilakukan secara eksperimental, dan perhitungan perubahan energi dalam dilakukan dengan menggunakan data suhu dan variasi laju aliran sirkulasi alami yang terjadi pada variasi suhu pada bagian pemanasan yaitu 40°C, 50°C, dan 60°C. Data perbedaan suhu diperoleh dari suhu masuk dan keluar pada heat exchanger dengan menjaga kondisi steady selama 5 jam dari total waktu percobaan 24 jam. Hasil percobaan menunjukkan bahwa perubahan energi dalam meningkat seiring dengan laju aliran sirkulasi alam yang terjadi.

Independence is a directed process because the development of independence is in line with the nature of human existence, the direction of development must be in line with and based on the goals of human life. But the reality in the field there are still students who have low learning independence, there are still many students who are low in the desire to compete to advance for their own good, less able to make decisions and initiatives to overcome problems, lack self-confidence in doing their tasks, and lack responsible for what he does. Independence of learning is the ability of students to realize their desires and take initiative in determining the learning activities such as formulating learning goals, learning resources (either in the form of people or materials) to diagnose learning needs and control the learning process without the help of others and one of the factors that influence it is student learning discipline. This study aims to determine the relationship between disciplines of learning with students' learning independence in Padang 2 Public High School. This research is a descriptive correlational research with quantitative methods. The total sample of 245 students was selected using the Simple Random Sampling technique. The research instruments used were learning discipline questionnaires and student learning independence questionnaires. The results of the study revealed that (1) the discipline of learning students in SMA Negeri 2 Padang was in the good category. (2) the learning independence of students in SMA Negeri 2 Padang is in a fairly good category (3) there is a significant relationship between the discipline of learning and student learning independence in SMA Negeri 2 Padang. Based on research findings, it is recommended that school counselors / counselors be able to provide guidance and counseling services, namely information services and individual counseling services in order to help students who have problems with learning independence.

This paper aims to gain an understanding of the characteristics of male couples of childbearing age, their participation in the family planning program and to assess the factors that influence men's participation in the family planning program in Muaro Jambi District. The problem in this study is focused on the low rate, where in 2018 only 1.3% consisted of 1.2% condom acceptors and 0.1% vasectomy acceptors (MOP). This achievement is very far behind when compared to the Jambi Province coverage of 2.5%. This condition illustrates the low participation of men in the family planning program in Muaro Jambi Regency. In order to approach this problem a reference is used from several factors that influence the low proda participation in the family planning program, including predisposing factors, supporting factors and driving factors. The data were collected through a direct interview survey to respondents using a questionnaire and analyzed using a quantitative method with a cross sectional design approach. This study concludes that knowledge is the most dominant factor associated with male participation in family planning programs in Muaro Jambi District. Men with good knowledge about family planning were 2.037 times more likely to participate in family planning programs than men with knowledge

Fasilitas simulasi sistem pasif (FASSIP-01) merupakan alat uji sistem pendinginan dengan memanfaatkan sistem sirkulasi alam yang di bangun di laboratorium thermohidrolika PTKRN BATAN. Untai uji FASSIP-01 terdiri dari beberapa komponen utama yaitu tabung cooler, heater, perpipaan, dan tabung ekspansi. Salah satu cara mengetahui karakteristika perpindahan panas dalam suatu sistem adalah dengan metode Finite Element Method (FEM) yang merupakan langkah menyelesaikan suatu problem dengan cara mem-bagi obyek analisa menjadi bagian-bagian kecil yang terhingga. Salah satu aplikasi berbasis FEM adalah ANSYS yang digunakan dalam simulasi ini. Makalah ini dikhususkan pada aplikasi ANSYS (student version) untuk mengetahui karakteristika perpindahan panas pada tabung cooler dengan variasi kecepatan dan variasi temperatur pada aliran tabung cooler yang dilewati oleh pipa panas bertemperatur 85 oC. Hasil simulasi adalah besar kalor yang dilepas air di dalam pipa dan penyerapan kalor oleh air di dalam tabung cooler. Hasil perhitungan menunjukkan bahwa semakin besar ke-cepatan aliran air yang masuk ke dalam tabung cooler, maka pendinginan yang terjadi juga semakin besar, sementara semakin kecil temperatur air yang masuk ke dalam tabung cooler, maka pendingi-nan yang terjadi juga semakin cepat.

Untai FASSIP-01 adalah fasilitas simulasi sistem pasif yang digunakan untuk menginvestigasi fenomena sirkulasi alami guna penguasaan kemampuan desain reaktor dengan sistem keselamatan pasif. Untai FASSIP-01 yang terdiri dari section berupa pipa stainless steel berdiameter 1 inch yang disusun membentuk untai rektangular dengan ukuran lebar 350 cm dan tinggi 600 cm. Komponen utama yang terpasang pada untai rektangular adalah tangki heater sebagai pemanas dan tangki cooler sebagai pendingin. Dalam rangka persiapan eksperimen, perlu dilakukan analisis awal untuk mengetahui unjuk kerja pemanas dan pendingin pada untai FAS-SIP-01. Analisis dilakukan dengan perhitungan berdasarkan data pengukuran yang diperoleh melalui variasi daya pemanas untuk mengetahui waktu optimal dalam proses pemanasan dan pendinginan. Hasil analisis menunjukkan bahwa pada daya total 20 kW, waktu yang dibutuhkan untuk mencapai temperatur air 75 °C adalah sekitar 0,48 jam. Begitu juga dengan kinerja refrigerator dan tangki pendingin, dimana bila kalor yang diserap refrigerator selama pendinginan semakin besar maka waktu pendinginan optimal akan semakin cepat tercapai.
