Abstract

Talang Gulo Final Disposal Site (FDS) has a Leachate Treatment Plant (LTP) equipped with denitrification and nitrification facilities which function to reduce the concentration of ammonia (NH3) in leachate according to predetermined environmental quality standards. Research samples were taken in the form of leachate using the grab sampling method in accordance with SNI 6989.59:2008. The results of the research showed that the aeration time for the ammonia stripper of 3 hours, 6 hours and 12 hours both gave the highest value for the ammonia stripper efficiency percentage variable. The highest ammonia removal efficiency is aeration time of 12 hours. However, if we look at the operating efficiency of the ammonia stripper, the removal of ammonia by using an aeration time of 12 hours does not provide a significant improvement when compared to a treatment with an aeration time of 6 hours. This means that the operating time is 6 hours faster, the 6 hour variation can provide an ammonia removal efficiency of more than 90%

Abstract

This research aims to identify the type and amount of B3 waste, identify B3 waste management based on Government Regulation Number 22 of 2021, as well as the SWOT strategy for B3 waste management in the Jambi City hotel industry. The research method is a mixed method. Data collection techniques were carried out by means of open interviews using questionnaires, documentation and literature studies. This research used two types of informants, namely 5 experts and 36 hotel staff, with a questionnaire as the data collection instrument. The results of this research are the type of B3 waste in hotels, namely used oil with the highest amount, namely 0.786 tonnes, and the smallest amount, namely used cloth, amounting to 0.009 tonnes. The research results also found that the hotels that produced the most B3 waste were 5-star hotels, amounting to 0.752 tons. The stages of B3 waste management implemented in the hotel industry are the reduction stage and the storage stage. In the SWOT diagram, it is in quadrant II, namely a combination of strategies between strengths and threats (ST strategy), namely central government regulations, administrative sanctions for hotels, reducing the use of B3 waste in hotels, preparing TPS for B3 waste not mixed with other waste, the government working together. with third parties for B3 waste management, inviting the public to protect the environment.

Abstract

Background: Blended learning is a learning approach that combines face-to-face (synchronous) and non-face-to-face (asynchronous) learning. This learning approach has been implemented in various schools in Tanjung Jabung Barat Regency. However, in its implementation there are obstacles, one of which is the teacher's lack of knowledge in developing appropriate media that can be used in implementing blended learning. The aim of this service activity is to train the creation of e-learning media to support blended learning for MGMP Biology teachers throughout Tanjung Jabung Barat Regency. Method: The workshop and mentoring activities are carried out by delivering material, discussion and practice. Result: all activities run well. Every teacher can create e-learning media for their learning. Conclusion: as many as 100% of participants stated that PPM activities were very useful, and 93% of participants were committed to implementing the e-learning media developed in their learning process.

Abstract

Kondisi pembelajaran kimia hijau disekolah saat ini masih berpusat pada guru, yang mengakibatkan literasi sains dan pencapaian hasil belajar murid belum tergarap secara maksimal. Selain itu, kurangnya media ajar yang bersifat kontekstual serta berorientasi pada penyelesaian masalah menghambat siswa dalam mengaitkan konsep materi kimia hijau dengan fenomena kehidupan sehari-hari. Oleh karena itu, penelitian ini bertujuan mengembangkan Lembar Kerja Peserta Didik (LKPD) berbasis Problem Based Learning (PBL) pada materi kimia hijau berorientasi literasi sains dan hasil belajar, serta menguji kelayakan dan respon siswa. Penelitian produk ini menerapkan metode Research and Development (R&D) dengan model Lee & Owens, meliputi tahapan analisis kebutuhan, desain, pengembangan, implementasi, dan evaluasi. Hasil uji validasi memperlihatkan tingkat kelayakan yang sangat tinggi, yakni 95% dari ahli media, 92% dari ahli materi, dan 88% dari guru, yang dikategorikan sangat layak. Respon siswa dalam uji coba juga tercatat sangat baik, yakni 91,52 pada uji satu-satu (one to one trial) dan 90,67% pada uji coba kelompok kecil (small group trial) yang menunjukan bahwa LKPD terbukti layak dan dapat dijadikan altenatif media pembelajaran yang efektif.
