Abstract

Population and economic growth causes an increase in waste production, especially plastic waste. Pyrolysis is the process of fracturing or breaking down polymer chains into simpler compounds through a thermal process (heating/burning) with little or no oxygen. Plastic waste can be decomposed and converted into fuel which has a high calorific value through the pyrolysis process. This research aims to determine and compare the capabilities of plastic pyrolysis oil with kerosene and diesel in terms of density, burning time, water temperature and volume of water lost (evaporated) when cooked using the oil. The research results show that 1) the density of pyrolysis oil is 0.8 g/ml. The time required to completely burn an object is 4.02 minutes. Cooking water using pyrolysis fuel oil produces a temperature of 75°C at a cooking time of 4 minutes with a volume of water lost (evaporated) of 12.6 ml. 2) Of the 4 parameters observed, the quality of pyrolysis oil is below kerosene but above diesel oil.

Abstract

Indonesia is an archipelago, and some cities began as coastal towns. Takalar, a coastal city, has experienced social, cultural, and economic development. The Galesong Coastal Area, located in Takalar Regency, South Sulawesi, has various aspects of social, cultural, and financial life, as well as a tourism sector. The relative sea level on the Galesong coast ranges between 6,203 and 6,274 mm per year. On the other hand, sea level rise has tremendous effects on climate change and marine disasters. Some of the effects produced by sea level rise include increased frequency and intensity of flooding, changes in ocean currents, greater mangrove damage, and increased threats to the socioeconomic activities of coastal communities. The purpose of this study is to identify the effects and sources of sea level rise and disasters, hence this study shows the impacts on coastal communities and surrounding marine ecosystems. Based on the declining terrain, socialisation and education of the community on disaster mitigation, and the creation of evacuation routes are some of the impacts that can be anticipated from sea level rise and disasters.

Abstract

Higher Order Thinking Skills (HOTS) merupakan salah satu kemampuan esensial guna mendukung pencapaian Sustainable Development Goals (SDGs). Hasil PISA 2022 menunjukkan bahwa lebih dari 80% murid Indonesia masih berada pada kategori lower order thinking, sehingga kemampuan HOTS masih tergolong rendah. Berdasarkan identifikasi permasalahan tersebut, penelitian ini bertujuan mengembangkan web-game dan worksheet berbasis PBL-etno Museum Kereta Api Ambarawa untuk mendukung peningkatan HOTS. Penelitian ini menggunakan metode Research and Development (RD) dengan model 4D hingga tahap Develop, meliputi proses validasi dan uji keterbacaan. Validasi dilakukan oleh dua ahli dan satu praktisi terhadap media pembelajaran, modul ajar, dan instrumen tes HOTS. Hasil validasi menunjukkan bahwa media pembelajaran memperoleh rata-rata 94%, modul ajar 92,2%, dan instrumen HOTS 90,7%, seluruhnya termasuk kategori sangat layak dan sangat valid. Uji keterbacaan melibatkan 26 murid dan menghasilkan skor 80,4% dengan kategori baik. Hasil tersebut menunjukkan bahwa web-game dan worksheet berbasis PBL-etno yang dikembangkan layak digunakan sebagai media pembelajaran interaktif, kontekstual, dan menarik untuk mendukung peningkatan HOTS murid sekaligus menanamkan apresiasi terhadap nilai budaya lokal.
