Abstract

The “Lentera” power plant is a 130 MW coal-fired power plant facility. The quality of the supplied coal to the “Lentera” power plant were tested using proximate and ultimate analysis to determine sulphur and nitrogen content. The production of SO2 and NOX emissions from coal combustion was affected by the sulphur and nitrogen content in the coal. Emission levels were observed using the Continuous Emission Monitoring System (CEMS). This research was conducted to determine the effect of the sulphur and nitrogen content in coal on the production of SO2 and NOX gas at "Lentera" power plant during June-December 2020. The analysis was done based on statistical analysis using simple linear regression methods and analysis of variance. Based on the content of sulphur, nitrogen and caloric value, coal from East Kalimantan Province has a lower value than coal from South Sumatra Province. The content of sulfur and nitrogen significantly affected the production of SO2 and NOX emissions. The higher the sulfur and nitrogen content in coal showed the higher the production of SO2 and NOX emissions. The caloric value of coal did not show a correlation with the production of NOX emissions.

Abstract

Abstrak: Pemanasan global merupakan fenomena yang mempengaruhi kehidupan manusia dalam berbagai aspek, termasuk kehidupan sehari-hari siswa. Oleh karena itu, media pembelajaran mengenai pemanasan global menjadi sangat penting. Penelitian ini bertujuan untuk mengetahui efektivitas penggunaan Instagram sebagai media pembelajaran yang inovatif dalam meningkatkan pemahaman siswa terhadap materi pemanasan global, serta menganalisis persepsi siswa terhadap media tersebut. Penelitian dilakukan di SMAN 2 Klaten kelas XI IPS 2 dengan sampel 35 siswa menggunakan desain pre-eksperimental (pra-tes dan pasca-tes). Hasil penelitian menunjukkan bahwa 86% siswa memiliki persepsi positif terhadap akun Instagram @fakta_globalwarming. Selain itu, terdapat peningkatan signifikan pada hasil belajar siswa setelah menggunakan Instagram sebagai media belajar dengan peningkatan rata-rata sebesar 27%. Hasil ini menunjukkan bahwa Instagram efektif digunakan sebagai media pembelajaran. Diharapkan hasil penelitian ini dapat menjadi dasar dalam mengembangkan strategi pembelajaran berbasis digital yang lebih menarik dan relevan di era industri 4.0. Abstract:  Global warming is a phenomenon that affects various aspects of human life, including students’ daily activities. Therefore, learning media that address global warming are critically important. This study aims to examine the effectiveness of using Instagram as an innovative learning medium to enhance students’ understanding of global warming and to analyze students’ perceptions of the platform. The research was conducted at SMAN 2 Klaten, class XI IPS 2, with a sample of 35 students using a pre-experimental design (pre-test and post-test). The results show that 86% of students had a positive perception of the Instagram account @fakta_globalwarming. In addition, there was a significant improvement in students’ learning outcomes after using Instagram as a learning tool, with an average increase of 27%. These findings indicate that Instagram is an effective learning medium. It is hoped that the results of this study can serve as a foundation for developing more engaging and relevant digital learning strategies in the era of Industry 4.0.

Abstract

Kendala geografis merupakan faktor utama terhambatnya distribusi PLN dalam memenuhi kebutuhan lsitrik masyarakat di Desa Jonggon Jaya, Kecamatan Loa Kulu, Kabupaten Kutai Kartanegera. Sehingga untuk memenuhi kebutuhan energi listrik dilakukan dengan menggunakan Genset. Kegiatan ini bertujuan untuk memberikan solusi alternatif bagi pengentasan masalah elektrifikasi dengan penerapan Teknologi PV-SHS (Photovoltaic-Solar Home System) yang memanfaatkan sumber energi matahari yang dikonversi langsung menjadi energi listrik. Tahapan kegiatan yang dilakukan dalam merealisasikannya, diantaranya perakitan Sistem PV-SHS, uji fungsionalitas dan perhitungan perkiraan kebutuhan energi listrik sesuai kebutuhan sehari-hari. Perangkat Sistem PV-SHS yang dihasilkan merupakan perangkat modular yang terdiri dari modul PV, charge controller, inverter, dan sistem beban (loading) dalam bentuk perangkat yang kompatibel sebagai penghasil energi listrik. Hasil uji fungsionalitas menunjukkan bahwa pengujian kinerja Sistem PV-SHS berpotensi tinggi untuk dikembangkan di daerah ini. Selain itu, upaya untuk menekan biaya investasi dilakukan dengan perhitungan perkiraan kebutuhan energi listrik harian untuk menghindari terjadinya over-sizing pada perancangan dan implementasinya.

Abstract

Geography Education students are expected to have literacy about the phenomena around them, one of which is Urban Heat Island (UHI) literacy. It is appropriate by the mission of Geography Education at the Muhammadiyah University of Surakarta (UMS) is to produce geography educators with a view on disaster mitigation. This study aims to determine the UHI literacy of students in 7th semester, Deparment Geography Education, Faculty of Teacher Training and Education, Universitas Muhammadiyah Surakarta. This research is a quantitative descriptive study with survey methods. The study using purposive random sampling of 80 respondents and as many as 54 collage students were selected as samples. The UHI literacy research instrument was developed based on the OECD's International Program for Student Assessment (PISA) in 1999. Based on the indicators in scientific literacy which are divided into three categories, the results are obtained: 1) Indicators of UHI's concepts show that high categories are middle class 20.4 % and the majority of students at a high level with 79.6%; 2) Indicators of UHI's processes obtained results with 1.8 % of students at a low level, 20.4 % of students at a medium level, and 78.8 % at a high level; 3) UHI's situation indicators showed that the high category was 93% and moderate was 7%. The conclusion shows that the UHI literacy of students is relatively high, indicating that curriculum based on disaster insight has been doing well, but further research is needed on other disaster insights and analysis of factors which affect the results above.Keywords: Urban Heat Island, Urban Heat Island Literacy, Curriculum
