Abstract

Tiga buah variabel bebas yang digunakan pada penelitian ini adalah Produktivitas Kerja, Ketersedian Peralatan dan bahan berpengaruh  terhadap kinerja proyek bangunan dan jalan PT. “Y”. Tujuan penelitian adalah untuk menganalisis seberapa besar pengaruh produktivitas Kerja, ketersedian peralatan dan ketersediaan bahan baik secara terpisah maupun secara bersama-sama terhadap kinerja PT. “Y”.Untuk menjawab tujuan penelitian tersebut dirancang masing-masing 15 pertanyaan. Kuesioner variabel penelitian dibuat berdasarkan dimensi dan indikator variabel penelitian yang disebarkan kepada sampel sebanyak 95 responden proyek bangunan dan jalan  PT. “Y”. Kemudian, ditentukan formula persamaan regresi setelah dilakukan uji validitas, uji reliabilitas, uji normalitas, uji multikolinieritas, dan uji heteroskedastisitas terhadap setiap hasil kuesioner dan skor baik untuk variabel terikat maupun variabel bebas. Berdasarkan hasil penelitian bahwa kinerja proyek bangunan dan jalan PT. “Y” dengan ketelitian 99% secara parsial dipengaruhi oleh produktivitas kerja sebesar 64,2 %, ketersediaan peralatan sebesar 54,8 % dan ketersediaan bahan sebesar 37,6 %. Secara simultan produktivitas kerja, ketersediaan peralatan, dan ketersediaan bahan dengan ketelitian 99% berpengaruh terhadap kinerja proyek bangunan dan jalan PT. “Y” sebesar 70,2 %. Hal ini membuktikan bahwa pengaruh ketiga variabel bebas yang digunakan untuk menentukan kinerja proyek bangunan dan jalan PT.”Y” adalah saling menunjang.

Abstract

Solar energy technology is one of the most rapidly advancing renewable energy solutions aimed at meeting electricity demands in a sustainable manner. This technology converts sunlight into electrical energy through two primary approaches: the photovoltaic (PV) system, which utilizes solar panels to directly transform sunlight into electricity, and the Concentrated Solar Power (CSP) system, which uses mirrors or lenses to concentrate solar heat for electricity generation. The main advantage of solar energy lies in its environmentally friendly nature, as it does not produce carbon emissions or harmful greenhouse gases. Moreover, solar energy is derived from the sun—a renewable and abundant source that will not deplete. Economically, solar technology offers long-term cost efficiency; after the initial installation, operational costs are relatively low and can significantly reduce or eliminate electricity bills. The versatility of solar applications is another key benefit, as it can be used for various needs, ranging from household systems to large-scale industrial projects. With these advantages, solar energy stands as a strategic alternative in supporting the transition toward a cleaner, more sustainable energy system and environmentally friendly, especially within the environment of Mpu Tantular University in Jakarta.
