This evaluation study aims to determine the profile of the implementation of learning programs in PNB in terms of components: 1) context, 2) input, 3) process, 4) products, and 5) linkages of learning program products with context, input and process components. The study was conducted at the Bali State Polytechnic in 2017/2018 . Object of research Student, Lecturer, Administrative Staff, and Head of department / Chair of the Study program. Research subjects were recruited proportionally stratified random sampling. The size of the sample was determined using the Krejcie table and Harry King's Nomogram based on a 5% error of 241 people. The research variable includes four main function variables for evaluating the implementation of learning programs. Data were collected with documentation and questionnaires and analyzed quantitatively and qualitatively. The results of the analysis show that the implementation of the learning program at the Bali StatePolytechnic when viewed from the components: 1) contex is effective, 2) input is effective, 3) process is effective, 4) product is ineffectiveis, and 5) the relationship between contex, input, process, and product is quite effective.

This study is aimed at finding out: (1) the level of effectiveness of the teaching implementation at a polytechnic education institution viewed from the interrelatedness of the components of context, input, process, and product, and (2) the constraints in the teaching implementation at the institution. This study used the Contex Input Process Product (CIPP) model from Stufflebeam. The data were collected using a questionnaire, interview guide, and related docu-ments. The subjects of the evaluation were the students, lecturers, and the top management staff of the departments at the polytechnic. The data were analyzed using a quantitative descriptive method. The effectiveness of the learning program is determined based on the results of the prototype verification in the Glickman quadrant. The results of the analysis show that the teaching program implementation at the polytechnic viewed from the inter-relatedness of context, input, process, and product is considered effective enough. The constraints in the implementation of teaching at the polytechnic are in teaching planning, implementation of semester teaching plans, curriculum, and infrastructure as well as facilities. Those constraints create other barriers to the achievement of learning outcomes, both academic and non-academic.

An evaporative cooling system for fruit and vegetable was designed, fabricated, and evaluated in this study. The evaporative cooling system is made of plywood covered with steorofoam. The inside system is made of plywood with dimensions of 30 cm x 30 cm x 30 cm. The inside of the box is covered with steorofoam with a thickness of 2 cm on the front, sides and back. The cooling pad in this evaporative cooling system is sintered zeolite. Sintering zeolite is a new material used to optimize evaporative cooling systems. One suction fan to draw environmental air through the cooling pad and into the controlled room. There is a water reservoir used to collect cooling water and place a cooling water circulation pump. The pump lifts water from the reservoir then sprays the cooling pad through the pipe and then the water is stored back in the reservoir. As water drips through the cooling pad, the suction fan keeps the air moving and blowing through the cooling pad. When passing through the cooling pad, the evaporation process occurs, and the cooling effect takes place.

Bali kaya akan potensi dan berbagai sumber daya alam yang dapat menunjang kehidupan masyarakat, salah satunya adalah padi yang banyak dimanfaatkan oleh masyarakat dan diolah menjadi beras sebagai bahan pokok nasi. Desa Jatiluwih, Kabupaten Tabanan merupakan salah satu daerah di Bali yang mempunyai potensi sektor pariwisata. Proses perontokan padi masih dilakukan secara manual menggunakan meja kayu atau dengan mesin perontok padi dengan motor bakar diesel. Proses kerja manual banyak membutuhkan tenaga dan waktu yang cukup lama dalam proses merontokkan padi, sehingga produktivitas menjadi rendah. Dipihak lain penggunaan mesin perontok padi bertenaga motor bakar diesel kurang ramah lingkungan. Untuk mengatasi masalah tersebut perlu upaya alternatif untuk memudahkan proses merontokkan padi yaitu dengan menggunakan mesin perontok padi dengan penggerak motor listrik dengan matahari sebagai sumber energi. Setelah dilakukan perhitungan, hasil perencanaan yang diperoleh, motor 200 watt dengan diameter poros 1 inchi dan bantalan yang digunakan adalah bantalan gelinding dengan diameter dalam 25 mm, gir 50 mata untuk di mata perontok dan 25 mata untuk di motor listrik dan rantai yang digunakan adalah tipe 428H dengan panjang 1000 mm. Dari hasil pengujian alat yang sudah dibuat diperoleh waktu rata-rata untuk merontokkan padi 14,642 detik.

The simulation design of this animal waste treatment plant is a design that applies the sewage treatment plant system which is made to cope with environmental pollution, especially rivers due to indiscriminate disposal of animal waste. Making this animal waste treatment plant provides information to readers or the public about how to design an animal waste treatment plant system and the performance of the sewage treatment system so that people know how to deal with environmental pollution caused by the livestock themselves. The manufacture of this installation system uses data collection methods from direct farmers and theories obtained from books, journals, articles related to sewage treatment plant theory, plumbing, electricity, and others. Finally, the data was collected by testing the animal dung waste treatment system where the test data was taken from the pH content of the water used for processing the animal dung waste treatment system. The test results on the sewage treatment plant system concluded that in order to obtain optimal results or water pH content, namely the pH content of 6, it is necessary to deposit animal manure between two to three days, while the maximum processing of this system is the pH content of 6.5. and processing of animal manure, which is on the fourth day to get the maximum pH content.
