Abstract

Mesin pendingin mempunyai fungsi sangat penting sehingga penelitian di bidang tersebut banyak dilakukan untuk terus mengoptimalkan unjuk kerjanya. Unjuk kerja mesin pendingin bisa dinilai dari nilai coefficient of performance (COP). Penelitian ini dilakukan untuk mengetahui pengaruh variasi tekanan kerja freon terhadap unjuk kerja mesin pendingin. Alat yang digunakan adalah alat peraga atau traine sistem refrigerasi. Kondisi freon divariasikan dengan tekanan 8psi, 10pis, 12psi, dan 14psi. Berdasarkan hasil penagukuran dan perhitungan dari empat variasi tekanan freon dapat disimpulkan bahwa tekanan optimum system refrigerasi tersebut dicapai pada tekanan kerja 10psi dengan nilai COP 2,86 dan efek refrigerasi 120kJ/kg.

Abstract

Kapal General Cargo adalah kapal yang mengangkut muatan berupa barang, sehingga syarat-syarat yang diperlukan oleh suatu kapal berlaku pula untuk kapal General Cargo. Namun demikian berbeda dengan jenis kapal umum lainnya seperti kapal Ikan, kapal Tanker mempunyai fungsi operasional yang berbeda. Dengan demikian konstruksi dan desain kapal General Cargo berbeda dengan konstruksi kapal Ikan atau Kapal Tanker. Tujuan perhitungan Konstruksi Profil dan beban kapal adalah untuk mendapatkan perhitungan kapal yang akan dibangun dengan baik dan dilakukan dengan perhitungan sesuai dengan data kapal. Beban Kapal terbesar berada dibagian Geladak Cuaca daerah Buritan yaitu sebesar 41,815 kN/m2. Beban terkecil berada dibagian Compas Deck yaitu sebesar 10,03 kN/m2. Perhitungan Profil L terkecil dibagian Frame Utama pada daerah Buritan Kapal sebesar 202,80 mm, Profil H terbesar berada dibagian Frame Utama pada daerah Haluan Kapal sebesar 259,50 mm dan Perhitungan Profil H terkecil dibagian Frame Utama pada daerah Midship Kapal sebesar 174,60 mm.

Abstract

The ability that the people must have is the ability to read, however beginner readers usually have difficulty reading. To overcome this, it is necessary to have effective learning media to overcome reading difficulties. This research aims to analyze the effectiveness of audio visual media in overcoming the reading difficulties of the people of Putat Village RT 02 RW 06. This research was conducted using descriptive qualitative methods. The object of this research is the effectiveness of using media to overcome reading difficulties. Data collection techniques in this research used interviews and distributing questionnaires. The data analysis technique in this research uses inductive qualitative analysis. Based on the results of the analysis, it can be concluded that the use of audio visual media is quite effective in overcoming reading difficulties in the people of Putat Village Rt 02 Rw 06. This data is strengthened by data from the results of distributing questionnaires that have been obtained. he data is in the form of a diagram which has percentages of 100%, 100%, 90.9%, 81.8%, and 81.8% which, if averaged, is 90.9%. Therefore, it can be concluded that the use of audio visual media can overcome reading difficulties.

Abstract

The purpose of this research was to describe the process of the implementation of student state Vocational School Prakerin in Purwodadi and test the difference Prakerin in state Vocational School and private Vocational Schools in Purwodadi. This research uses research survey that is descriptive. The population of this research is the grade I Concrete Masonry Construction Engineering (TKBB) of state Vocational School and private vocational schools in Purwodadi. The Sampling technique used was Simple Random Sampling. The results of the research implementation process of state Vocational School that is as much as 10 students (21.74%) stated the very high category, 31 students (67.39%) including the categories high, by as much as 5 students (10.87%) stated the categories and score an average of 141.26. Results of the study in private vocational schools show that as many as 8 students (17.39%) including the very high category, 14 students (30.43%) said the high category, as many as 14 students (30.43%) including categories and score an average of 134.37. The results of calculation using SPSS t-Test of can to score t of extent and significance is 3.794 0.000 < 0.05 so the hypothesis described there are differences in the implementation process state Vocational School and private Vocational Schools in Purwodadi was supported by the data. Implementation of students state Vocational School Prakerin including categories higher and private Vocational Schools categories include enough.

Abstract

At this time technology can no longer be avoided, various sectors can take advantage of it, including the education sector. The way that can be utilized is by using learning media during the learning process because it will create a comfortable, enjoyable and interesting atmosphere to obtain maximum results. The aim of this research is to explain and identify the influence of using audio-visual learning media on vocational school student learning outcomes. This research aims to determine the effect of audio-visual learning media on vocational school student learning outcomes. To get what is desired, a quantitative research approach is used with experimental types and a Quasi Experimental research design. Data is calculated using statistical calculations (SPSS). In this research, simple linear regression analysis and t test were used. Testing the hypothesis with the t test obtained a t count value of 10.733 it means t hitung > t table (10.733 > 1.699) and significance (0.000 < 0.05) so it can be concluded that there is an influence of Audio Visual Learning Media on Vocational School Student Learning Outcomes.
