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

Scientific literacy is one of the main keys for education personnel in facing the challenges of the 21st century which continues to experience global changes. Project learning is carried out to increase scientific literacy and achieve sustainable development. This study aims to describe the scientific literacy profile of vocational students in the application of green chemistry-based electroplating learning projects. The principles of green chemistry raised in the electroplating project are the use of safe chemicals, the use of green solvents, and waste prevention. The research method used was a descriptive analysis. The research subjects were 27 students from the Industrial Mechanics Engineering program in the Department of Technology and Engineering at a Vocational School in the city of Cimahi for the 2022-2023 Academic Year, selected using the convenience sampling technique. Data collection techniques were carried out using 20 scientific literacy test instrument questions with four answer choices that have been validated and tested for reliability. Data analysis was carried out by paired t-test on pretest and posttest values using the Microsoft Excel program. The scientific literacy profile of SMK students in the domain of science knowledge is categorized as low with a percentage of 48%, the scientific competence domain is categorized as moderate with a presentation of 66%, and the attitude domain is categorized as moderate with a percentage of 63%.

Abstract

Masa pandemi Covid-19 yang telah berlangsung selama hampir dua tahun menyebabkan siswa kehilangan kesempatan untuk melakukan kegiatan laboratorium. Kondisi tersebut menjadikan pembelajaran kimia lebih bersifat teoritis. Hal ini menjadi salah satu penyebab rendahnya minat dan motivasi siswa untuk mempelajari kimia yang pada akhrinya dapat berimbas pada rendahnya hasil belajar siswa. Oleh karena itu, kegiatan pengabdian kepada masyarakat ini dilakukan untuk mengetahui minat, motivasi, dan tanggapan para siswa terhadap pelajaran kimia melalui demonstrasi berbasis chemistry for fun. Sebanyak 12 judul percobaan kimia sederhana didemonstrasikan terhadap 54 siswa kelas X-XII di SMAN 1 Pangandaran. Pengumpulan data dilakukan dengan angket tanggapan para siswa terkait keterlaksanaan demonstrasi kimia berbasis chemistry for fun serta minat dan motivasi belajar siswa terhadap pelajaran kimia. Hasil analisis menunjukkan bahwa para siswa memberikan tanggapan positif terhadap demosntrasi kimia berbasis chemistry for fun dengan tingkat keterlaksanaan sangat baik. Selain itu, tingkat minat dan motivasi belajar siswa terhadap pelajaran kimia masing-masing berada pada kategori tinggi dengan presentase 64,8% dan 70,4%. Dengan demikian, demonstrasi kimia berbasis chemistry for fun dapat menjadi alternatif metode pembelajaran untuk meningkatkan minat dan motivasi belajar siswa terhadap pelajaran kimia.

Abstract

Dalam proses pembelajaran di abad ke 21 menekankan proses yang berpusat pada siswa (student center). Berbagai pendekatan yang dilakukan oleh guru agar siswa tidak mengalami tekanan/stres dalam pembelajaran, diantaranya dengan pendekatan emphaty dan mindfulness Penelitian ini mendeskripsikan profil emphaty dan mindfulness dalam pembelajaran kimia. Metode yang digunakan dalam penelitian ini adalah desktiptif dan naratif berdasarkan hasil pengamatan siswa terhadap subjek penelitian sesuai fakta ketika siswa mengikuti pembelajaran kimia di kelas. Instrumen yang digunakan berupa lembar skala sikap menggunakan model Guttman (dua pilihan jawaban ya/tidak) serta uraian terbatas melalui spreadsheet dalam google-form. Hasil penelitian menunjukkan hampir seluruh guru kimia sudah menerapkan pendekatan emphaty dan mindfulness di kelas dengan saran perbaikan berupa menjalin hubungan dan komunikasi yang lebih baik serta memberi saran dan solusi terhadap masalah yang dihadapi siswa.
