Penelitian ini bertujuan untuk mendeskripsikan dan mengetahui: (1) Pengaruh Budaya Organisasi Terhadap Kepuasan Kerja; (2) Pengaruh Budaya Organisasi Terhadap Motivasi Berprestasi; (3)Pengaruh Budaya Organisasi Terhadap Komitmen Organisasi; (4) Pengaruh Kepuasan Kerja Terhadap Komitmen Organisasi; dan (5) Pengaruh Motivasi Berprestasi Terhadap Komitmen Organisasi SMP Negeri Kecamatan Simanindo dan Kecamatan Pangururan Kabupaten Samosir. Metode penelitian yang digunakan adalah metode survei yang bersifat exploratori.Jumlah responden sebanyak 158 orang yang diambil dengan sampling random proporsional. Instrumen penelitian berupa angket, sedang analisis data lewat analisis jalur dan sebelumnya ada uji normalitas data dengan liliefors, uji linieritas dan keberartian regresi dengan Analisis Variansi pada taraf signifikansi α sebesar 0,05. Hasil dari penelitian ini ditemukan: (1) terdapat pengaruh langsung positif budaya organisasi terhadap kepuasan kerja dengan koefisien jalur  = 0,210 , dengan pengaruhnya sebesar 4,41%; (2) terdapat pengaruh langsung positif budaya organisasi terhadap motivasi berprestasi dengan koefisien jalur ρ31 = 0,381dengan pengaruhnya sebesar 14,51%; (3) terdapat pengaruh langsung positif budaya organisasi terhadap komitmen organisasi dengan koefisien jalur ρ41 = 0,216 dengan pengaruhnya sebesar 4,66%; (4) terdapat pengaruh langsung positif kepuasan kerja terhadap komitmen organisasi dengan koefisien jalur ρ42 = 0,269 dengan pengaruhnya sebesar 7,23%; (5) terdapat pengaruh langsung positif motivasi berprestasi terhadap komitmen organisasi dengan koefisien jalur ρ43 = 0,187 dengan pengaruhnya sebesar 3,49%. Semakin tinggi pengaruh budaya organisasi, kepuasan kerja, dan motivasi berprestasi guru, maka semakin tinggi pula dalam mempengaruhi komitmen organisasi guru SMP Negeri kecamatan Simanindo dan kecamatan Pangururan kabupaten Samosir.

The potential of solar energy as a renewable energy source is widely available in nature. Sunlight is abundant and even for tropical countries, the sun shines almost all year round. Therefore, solar power plants are very suitable for application in Indonesia. Solar electrical energy is generated by components called solar panels. This component converts energy from sunlight into electrical energy. Solar Reflector used in solar panels is a mirror. A plane mirror is a mirror that has a flat surface like a straight line, where one surface is coated with a reflecting metal so that the surface of the flat mirror can reflect more than 95 percent of the light that hits it. In this research, reflectors were added to the solar panels on the right and left sides. The reflector on the solar panel is shaped at an angle of 70 degrees. The reflector serves to optimize the light around the solar panel and focus the light towards the solar panel so as to produce greater output power. The highest voltage and watt are at 11.00 AM. 27 July 2021 is good condition for solar panels with average 19.63 V and 56.81 W.

This study aims to see the effectiveness of using Google Clasroom-aided blended learning for vocational teacher candidates. The effectiveness of blended learning in terms of the socialization of knowledge transfer and the internalization of knowledge transfer for vocational teacher candidates is good, in order to be able to adapt it for learning in vocational high schools. In detail the research was carried out to find: (1) the effective use of methods and strategies in the Google classroom assisted blended learning model for prospective teachers, (2) the effective use of the tools, media, and learning resources used in the Google classroom assisted blended model for prospective teachers , (3) the effectiveness of learning management on the use of google classroom assisted blended for prospective teachers, and (4) the effectiveness of learning outcomes using blended learning for prospective teachers. The research method uses a development and evaluation approach. The development approach is used to develop methods, strategies in the blended model that are used, while the evaluation approach is carried out to evaluate the results of development used. The results showed that: (1) he use of models and strategies in the Google classroom assisted blended learning model is very effective (3, 88) for prospective teacher students, (2) The use of tools, media, and learning resources used in the Google classroom assisted blended model very effective (3.86) for prospective teacher students, (3) Management of learning in the use of google classroom-assisted blended has been very effective (3.88) for prospective teacher students, and (4) learning outcomes in the use of Google-assisted blended assisted classroom learning outcomes Students are better than before using Google classroom assisted blended.
