Abstract

Abtract: The effect of R410 Refrigerant Mass Variation of The Low Stage Side on Performance of Cascade Engine Cooling. The aim of this research is to determine the effect of changes in the mass variation of refrigerant R410A in the Low - Stage Cooling on the coeficient of performance of the cascade refrigeration. The benefits of this research is to contribute valuable knowledge in the field of refrigeration, especially in the areas of health, agriculture and fisheries. The research method used is to perform testing or direct observation of the cascade refrigeration by replacing the stuffing or the mass of refrigerant in the low - stage of cascade system. Variation of refrigerant mass is 180, 190 and 200 gram. Any variations were observed mass of the pressure and temperature at a predetermined test points. The results showed that at the same time the rising in cooling capacity of the machine cascade with increasing refrigerant mass speed. With a mass of 180 gram showed a significant increase in weight compared to other masses, where a higher cooling capacity kW at 0.39 and coefficient of performance is 1.23.   Keywords :  Mesin refrigerasi, cascade, refrigeran R410A

Abstract

This aim of the study was to experimentally analyze the natural frequency (wn) of fiberglass reinforced polymer composite beam. The study used the spectrum method for experimental analysis. The spectrum method for experimental analysis was done by various position of 5 exciters. The supports used were a fixed-free (cantilever) with the material of fiberglass reinforced polymer composite in the form of beam with length 50 cm, width 3 cm, and thickness 2 cm. Composite material consisted of two compositions that was 5 % of fiberglass and 20 % of fiberglass. The devices used in the study was testing machine, IRD mechanalysis comprising vibration sensor, speed regulation unit, tachometer, and vibrator engine. The measurement was done on deflection, frequency response function, and spectrum. The results of the study obtained : For experimental analysis, at percentage of fiberglass   5 %, value wnmax = 13125 rpm, wnmin = 12600 rpm, whereas the percentage of fiberglass 20 %, value wnmax = 13230 rpm, wnmin = 12990 rpm.

Studi ini dilatarbelakangi oleh kegiatan penanaman nilai-nilai keagamaan yang dilaksanakan oleh organisasi Bundo Kanduang Andakasuma Nusa Sulawesi Utara dan strategi yang digunakan dalam melaksanakan kegiatan tersebut agar lebih efektif dan merasa pantas dengan adat istiadat yang dipegang teguh oleh masyarakat Minang yaitu Adat Basandi Syarak dan Syarak Basandi Kitabullah.Penelitian ini dilakukan menggunakan metode Kualitatif, karena penelitiannya dilakukan pada kondisi yang alamiah agar lebih mudah disesuaikan apabila berhadapan dengan kenyataan jamak dan menyajikan secara langsung hakikat hubungan antara peneliti dan responden. Tujuan penelitian untuk mengetahui (1) bagaimana peran organisasi Bundo Kanduang Andakasuma Nusa dalam melaksanakan pendidikan Islam di Manado, (2) faktor pendukung dan penghambat organisasi Bundo Kanduang Andakasuma Nusa dalam melaksanakan pendidikan Islam di Manado. Pengumpulan data yang digunakan yakni melalui observasi, wawancara dan dokumentasi.Hasil temuan penelitian ini menunjukkan bahwa peran organisasi Bundo Kanduang Andakasuma Nusa sebagai ajang silaturahmi terhadap anggota yang dijadikan sebagai sarana untuk saling berbagi ilmu khususnya membahas pendidikan Islam. Sehingga Bundo Kanduang Andakasuma Nusa merupakan wadah pemersatu terhadap anggotanya dalam mengembangkan pendidikan Islam. Disamping itu telah terbentuk Tahfidz Qur’an sebagai lembaga pendidikan Islam yang dibuka untuk umum. Faktor pendukung berupa fleksibilitas keanggotaan yang merangkul, adanya semangat pengurus untuk perkembangan organisasi menjadi besar, semangat anggota yang aktif untuk terus belajar pendidikan Islam. Faktor penghambat berupa sarana dan prasarana yang masih perlu untuk ditingkatkan, kurangnya kehadiran dari anggota untuk mengikuti kegiatan rutin, kurangnya disiplin dari beberapa anggota yang sering terlambat datang, serta adanya keterbatasan waktu membahas materi seputar pendidikan Islam yang hanya setiap sekali dalam dua minggu.

Abstract

This research aims to determine the effect of using the focus group discussion method on students' enthusiasm for learning in the Islamic religious education subject class VIII SMPN 1 Sungai Pua. This research uses a quasi-experimental research method by taking two classes which are used as a control class and an experimental class. This research is a quantitative experiment, by giving pre-tests and post-tests to students in both classes. Totaling 50 people. The sampling technique was carried out using Cluster random sampling technique. The instrument used for data collection was a learning interest questionnaire. The data analysis technique uses normality, homogeneity tests, then continues with hypothesis testing. From the research results, it shows that the results of hypothesis testing that was carried out in the experimental class and control class obtained a Sig value. (Pvalue) = 0.001˂ α = 0.05. which means H0 is rejected and Ha is accepted. Based on the results of these calculations, it can be concluded that there is an influence of using the focus group discussion method on students' enthusiasm/interest in learning in class VIII Islamic Religious Education subjects at SMPN 1 Sungai Pua.

Abstract

This study examines the ability of summation operations in deaf students. The purpose of this study is to find out: 1) The ability of summation operations in grade II deaf students at UPT SLB Negeri 2 Jeneponto during the initial conditions, 2) Improvement of summation operation ability with ultrasy (numeracy snakes) in grade II deaf students at UPT SLB Negeri 2 Jeneponto during intervention, 3) Improvement of summation operation ability with ultrasi (numeracy snakes) in grade II deaf students at UPT SLBN 2 Jeneponto after being given intervention, 4) Improvement of the summation operation ability of grade II deaf students at UPT SLB Negeri 2 Jeneponto after using ultrasy (numeracy snakes and ladders) based on the results of the analysis of initial conditions, conditions when given intervention and conditions after being given intervention. This study used an experimental method with a single subject research (SSR) with an A-B-A design. The results of this study can be concluded: 1) the summation operation ability of AQ subjects before being given treatment is very low based on baseline conditions 1 (A1), 2) the ability of the addition operation of AQ subjects during treatment increases to a high category seen from the analysis under intervention conditions (B), 3) the ability of AQ subjects addition operations after treatment decreases to sufficient categories can be seen from baseline conditions 2 (A2), 4) improvement in the operation ability of summation of AQ subjects based on the results of inter-condition analysis, namely in the conditions before being given treatment, students' ability was very low, increased to the high category during treatment, and from the high category in conditions during treatment decreased to sufficient categories after being given treatment, but the scores obtained by AQ subjects were higher than before being given treatment.
