Kata kunci: Petunjuk praktikum; video tracking; minat mahasiswa. ABSTRACTThis study is conducted to produce practical video tracking-based instructions that are valid, effective, and can increase student interest in the frictional force material on an inclined plane. The method used in this study was Research and Development (R&D) concerning the 4D development model (Define, Design, Develop and Disseminate). In general, the developed practicum instructions had covered two topics of activity, namely the determination of the coefficient of static friction by manipulating the slope of the plane and the coefficient of kinetic friction by analyzing the motion of objects on an inclined plane. Practical instructions in the design adopted a closed practicum/experimental model. The results of expert validation which include aspects of the feasibility of content, presentation, linguistic components, and implementation indicated that the practicum instructions developed were estimated valid with an average score of 4.03 and were suitable for use. On the other hand, the results of the practicality test consisting of components of attractiveness, ease of use, and the benefits of the developed practicum instructions were also considered practical with an average score of 3.93. Moreover, the results of the effectiveness test on the practicum instructions showed that this development product was considered effective for increasing student interest (high category). Thus, it can be concluded that this video tracking-based practicum guide product is valid, practical, effective to be used as a practicum guide, and is able to increase student interest. Keywords: Practical Instructions; video tracking; student interest.

ABSTRAKPenelitian ini bertujuan untuk mengetahui prinsip dasar dan sistem kerja pembangkit listrik tenaga mikrohidro (PLTMH) dari sudut pandang fisika sebagai upaya penyediaan dan pengembangan sumber belajar kontekstual. Penelitian ini dilaksanakan menggunakan metode studi literatur, observasi, dan wawancara. Hasilnya ditemukan bahwa PLTMH memiliki tiga komponen utama yakni air sebagai sumber energi, turbin, dan generator. Skema konversi energi pada PLTMH yang menggunakan head adalah sebagai berikut: 1) energi potensial air dari reservoir diubah menjadi energi kinetik pada pipa pesat, 2) energi kinetik air diubah menjadi energi mekanik oleh turbin air, 3) energi mekanik diubah menjadi energi listrik oleh generator. Turbin air berdasarkan prinsip kerja dibagi atas turbin impuls dan turbin reaksi. Turbin impuls memanfaatkan perubahan momentum air sebelum dan setelah menabrak sudu turbin, sedangkan turbin reaksi memanfaatkan perbedaan tekanan pada permukaan sudu. Generator bekerja berdasarkan prinsip induksi elektromagnetik. Ketika rotor generator yang terkopel pada turbin berputar, kumparan konduktor akan memotong garis medan magnet sehingga timbul tegangan induksi. Kata kunci: pembangkit listrik tenaga mikrohidro; konversi energi; turbin, generator. ABSTRACTThe research aims to determine the fundamental principles and working systems of Microhydro power plants from a physical standpoint as an effort to provide and develop contextual learning resources. This study was conducted using literature, observation and interview methods. The results found that PLTMH had three main components i.e. water as energy source, turbine, and generator. The energy conversion scheme on PLTMH that uses the head is as follows: 1) The potential energy of water from the reservoir is converted into kinetic energy on the rapid pipeline, 2) water kinetic energy converted into mechanical energy by water turbine, 3) changed mechanical energy into electrical energy by generators. The water turbine based on the working principle is divided into impulse turbines and reaction turbines. The impulse turbine utilizes a change in water momentum before and after crashing the turbine's sudu, while the reaction turbine utilizes pressure differences on the surface of the Sudu. The generators work based on electromagnetic induction principles. When the rotor generator is attached to the turbine spinning, the conductor coil will cut off the magnetic field line so that the induction voltage arises. Keywords: microhydro power plant; energy conversion; turbine; generator.

This study aims to determine the feasibility level of physics worksheets and to figure out the increase on student’s understanding after using the physics worksheets based on science process skills. This study is a development research employing ADDIE development model which consists of five stages, namely: analysis, design, development, and implementation. The design of this study was One Group Pretest-Posttest Design. The instruments used were validity assessment sheet, feasibility assessment sheet, questionnaire about the students’ response toward the worksheets based on science process skills, and assessment of science process skills. the data were analyzed by using percentage of agreement (R), and N-gain (g). The results showed that the physics students’ worksheet based on science process skills was feasible and could be used in learning as the feasibility level reached 97%. The students’ understanding of fluid material gained through working with the worksheets can improve students’ science process skills both at the basic level and at the integrated level. This is proven by the results of the initial test or pre-test which indicate that the students' science process skills affected the learning outcomes obtained in which 62.25% of students’ scores were in good category and 35.75% of students’ scores were in fair category. Meanwhile, in the final test or post-test of students' science process skills, it was obtained that 74.50% of students’ scores were in very good category and 25.50% of students’ scores were in the fair category. This means that there is an increase by 0.7 % in students' science process skills when using the students’ worksheets.
