Abstract

The energy crisis is a serious issue that all countries around the world are dealing with, particularly the energy sources used to generate electricity. There are numerous alternative energy sources available in nature, such as solar energy, wind energy, and so on. Wind and solar energy as hybrid energy sources are thought to be promising in electric generation technology. Hybrid Power Plants can also be used to address the issue of limited electrical energy supply in Indonesia's remote areas. The purpose of this study is to describe the effectiveness of the hybrid power plants implementation in Indonesia. The study was conducted using the narrative literature review method. It can be inferred that the purpose of developing this hybrid technology, among others, is to obtain more efficient electrical energy generation by combining the advantages of two or more types of power generation systems that work in an integrated manner as a compact system. The produced electric energy can be stored in the battery. In terms of use, the produced direct current (DC) is converted into alternating current (AC) using the inverter system prior to distribution to consumers. Therefore, this hybrid power plant is suitable to be implemented in Indonesia.

Abstract

masalah dengan menggunakan langkah-langkah sistematis layaknya komputer. Kemampuan computational thinking berkaitan erat dengan mathematical habits of mind jika dikaitkan dengan pemecahan masalah yang tidak mudah untuk dipecahkan. Mathematical habits of mind adalah kecenderungan untuk berperilaku cerdas ketika menghadapi permasalahan matematika yang sukar untuk dikerjakan. Penelitian ini bertujuan untuk mendeskripsikan kemampuan computational thinking peserta didik SMP kelas VIII ditinjau dari kategori mathematical habits of mind. Penelitian ini menggunakan pendekatan kualitatif dengan studi kasus. Subjek penelitian ini adalah  peserta didik kelas VIII di salah satu SMP Negeri di Kota Bandung yang telah mempelajari materi bangun ruang sisi datar. Data yang diperoleh dari penelitian ini menggunakan angket mathematical habits of mind, tes kemampuan computational thinking, dan wawancara. Hasil penelitian menunjukkan bahwa peserta didik dengan mathematical habits of mind tinggi memenuhi seluruh indikator computational thinking, yaitu dekomposisi, pengenalan pola, abstraksi, dan berpikir algoritma. Peserta didik dengan mathematical habits of mind sedang juga memenuhi seluruh indikator computational thinking. Peserta didik dengan mathematical habits of mind rendah hanya mampu dua indikator computational thinking, yaitu dekomposisi dan pengenalan pola, mereka belum mencapai indikator abstraksi dan berpikir algoritma.
