Carbon emissions are a significant cause of climate change. As an effort to reduce emissions in the university environment, carbon footprints at Diponegoro University (Undip) need to be calculated to find out how much campus activity contributes to the emissions produced and analyze scenarios that can be applied in minimizing them. The carbon footprint study at Undip was carried out in 3 scopes according to The Greenhouse Gas Protocol. Scope one covers clean water treatment activities. Scope two covers electricity usage activities, while scope three covers transportation, wastewater, and solid waste treatment activities in the campus environment. Carbon footprint emissions from the three scopes are calculated based on methods from the International Panel on Climate Change (IPCC). Emissions calculated are CO2, CH4, and N2O expressed in TonCO2-eq. The carbon footprint resulting from campus activities at Undip is 16, 345.83 TonCO2-eq. The first and second-largest carbon footprint contributors came from electricity and transportation activities with a total carbon footprint of 13, 953.22 TonCO2-eq and 1, 449.99465 TonCO2-eq, respectively. The emission reduction business strategies that can be carried out are through conservation and energy efficiency approaches as well as the use of Campus Buses and increasing the number of green space.
Coagulation-flocculation process is one of the first step of wastewater treatment. Coagulant aid as flocculant material is an essential for it's treatment successfully as an important factor for the next step processes. Although, flocculant fron unnatural polymer have potentially to cause environmental contamination and may affect to human health due to its persistent in environment and difficulties to degraded. This paper examines some of the natural flocculants that have been developed and their potential used to wastewater treatment. A type of natural flocculant that is widely developed to treat wastewater is cassava starch. Plant seed extracts such as from Plantago ovata were able to remove turbidity was > 90% at pH 6-8. Flour of Moringa oleifera Lam seeds are used to treat various types of wastewater with the ability to remove color and turbidity was > 90%. Tamarindus indica pods seed, able to remove golden yellow was 60% and was 25% for direct fast scarlet. The latest development was used durio seed to treat leachate that showed high potential as natural flocculant. Natural flocculant application for water and wastewater treatment is able to decrease of energy using to production and commercialization of it.
The purpose of this study is to describe the application of the active learning approach in inviting students to be able to think critically, be more creative, able to take roles, and be able to apply them. The research model is library research, research data from primary sources and secondary data. Then the data is processed by concept analysis. The conclusion of this study in the learning of PAI needs to be built an atmosphere such as encouraging learning is very important to attract students' interest in absorbing and interpreting the lessons that have been delivered by educators. Contextualizing the PAI material with other materials will make the students' understanding more comprehensive and integrate it with other subjects that can be easily understood. When a student understands the material received, the educator can ensure that the student is able to contextualize the material. Creativity and foresight of educators on social and cultural conditions must be able to illustrate the PAI material so that the material does not seem outdated and can be applied in appropriate conditions and conditions. This is also to facilitate students in understanding the material and its implementation in real life. Keywords: Implementation of Active Learning, PAI Learning Abstrak: Tujuan dari penelitian ini untuk memaparkan penerapan pendekatan active learning dalam mengajak peserta didik untuk mampu berpikir kritis, lebih kreatif, mampu mengambil peran, dan mampu menerapkannya. Model penelitian ini adalah library-research, data penelitian dari sumber primer dan data sekunder. Kemudaian data-data ini diolah degan analisa konsep. Kesimpulan peneletian ini dalam pembelajaran PAI perlu dibangun suasana seperti pembelajaran yang menggembirakan sangat penting untuk menarik minat peserta didik dalam menyerap dan menginterpretasikan pelajaran yang telah disampaikan oleh pendidik. Dengan mengkontekstualkan materi PAI dengan materi yang lain, akan membuat pemahaman peserta didik menjadi lebih menyeluruh dan mengintegrasikannya dengan mata pelajaran lain yang dapat dengan mudah untuk dipahami. Ketika seorang peserta didik memahami materi yang diterima, maka pendidik bisa memastikan bahwa peserta didik tersebut mampu mengkontekstualkan materi tersebut. Kreativitas dan kejelian pendidik terhadap kondisi sosial dan budaya, harus mampu mengilustrasikan materi PAI agar materi tidak terkesan ketinggalan zaman dan mampu diterapkan dalam keadaan dan kondisi yang sesuai. Hal ini juga untuk memudahkan peserta didik dalam pemahaman materi serta implementasinya dalam kehidupan nyata. Kata Kunci: Penerapan Active Learning, Pembelajaran PAI
Abstract. Livestock waste from cattle farms in Tekelan village, Getasan Subdistrict, Semarang Regency can be grouped into three types, namely solid waste, slurry and waste water. Solid waste (cow dung) was processed into compost, while slurry and waste water were used to make liquid fertilizer. This compost was used as a component of planting media in horticultural crops and potted plants production. We evaluated the toxicity (phytochemical and ecotoxicological) test of compost by using germination index (GI). Vigna radiata seeds are sown on filter paper dampened with compost extract for different times. GI was calculated by relative germination (G) and relative radical length (L). The germination index (GI) = G / G0 x L / L0 x 100, where G0 and L0 are values obtained by distilled water as a control. The results showed that germination bioassay and radical length using aquades and groundwater in Tekelan village did not affect the radical length of Vigna radiata . Technically, groundwater in Tekelan village can be used as a germination bioassay control. The cow dung compost substrate appears to have a major influence on compost toxicity. Mature compost was produced on day 14 with a GI of 104.03.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
