Abstract

The improper waste management in RT 041 Liliba, Kupang City, has become an urgent environmental issue. Organic and inorganic waste are often discarded without proper segregation, contributing to air and soil pollution. To address this, a training and mentoring program was implemented focusing on waste segregation, managing plastic waste through the Waste Bank, and processing food waste into liquid fertilizer and compost. The program involved 30 participants, including RT administrators and local residents. The results showed an improvement in community awareness and knowledge about waste segregation and management, as well as increased participation in the Waste Bank program and fertilizer production. It is hoped that this initiative can be continued and expanded to other communities in Kupang City to create a cleaner and healthier environment. The success of this program highlights the importance of collaboration between the community, RT administrators, and other stakeholders in managing waste responsibly and sustainably.

Abstract

1,1,1-Trichloro-2,2-bis(4-chlorophenyl) ethane (DDT) is a persistent organic pollutant that remains a global environmental concern due to its high toxicity and recalcitrance. This study investigated the ability of the white-rot fungus Phlebia brevispora to degrade DDT in a nutrient-rich Potato Dextrose Broth (PDB) medium under a short incubation time. The fungus degraded 64.25% of DDT within 7 days. Metabolites identified by GC/MS were DDE (1,1-dichloro-2,2-bis(4-chlorophenyl) ethylene), DDD (1,1-dichloro-2,2-bis(4-chlorophenyl) ethane), and DDMU (1-chloro-2,2-bis(4-chlorophenyl) ethylene), indicating both reductive dechlorination and dehydrogenation pathways. The results demonstrate that P. brevispora has strong potential for rapid biotransformation of DDT in nutrient-rich environments.

Abstract

Methylene blue is a textile dye with carcinogenic and mutagenic properties which can cause various problems for the environment and organisms, therefore it is necessary to treat the waste. This study describes the adsorption of methylene blue using base-activated coconut coir. Coconut coir as waste was prepared into 80 mesh-sized powder and then activated using NaOH solution. The base-activated coconut fiber was then used for methylene blue adsorption under several optimization conditions such as pH, contact time, concentration, and adsorption isotherm. The determination of methylene blue was adsorbed by the adsorbent measured using UV-VIS. The pH and contact time results were 7 and 75 minutes, respectively, with the adsorption capacity (qe) of 1.98 mg g-1 and 99.91%. The isotherm adsorption of blue methylene followed the Langmuir isotherm model with the maximum adsorption capacity (Qmax) of 0.2 mg -1. The result showed that the coconut fiber base activated could be used as a dye adsorbent.

Abstract

This study aims to: (1) evaluate the validity of the Problem-Based Learning (PBL)-based Student Worksheet (LKPD) used in chemistry teaching, particularly on the topic of Colligative Properties of Solutions; (2) evaluate learning outcomes in terms of knowledge and skills among 11th grade students at SMA Negeri 1 Titehena after using PBL-based LKPD; and (3) analyze student responses to the developed LKPD media. This study used a research and development design, involving a sample of 11 students from class XI MIA 2. The tools used included a PBL-based LKPD validation sheet, a learning outcome assessment sheet for KI-3 and KI-4 competencies, and a student response questionnaire. The data analysis techniques applied included: LKPD Media Validity Analysis, Learning Mastery Analysis, and Student Response Analysis. The results of the study show that: (1) the PBL-based Student Worksheet (LKPD) developed by the researcher is found to be highly valid and suitable for use; (2) students achieved learning mastery with an average score of 95; and (3) student responses to learning using PBL-based LKPD media were categorized as very positive, with a percentage score of 94%.ABSTRAK Penelitian ini bertujuan untuk: (1) mengevaluasi validitas Lembar Kerja Peserta Didik (LKPD) berbasis Problem-Based Learning (PBL) yang digunakan dalam pengajaran kimia, khususnya pada topik Sifat Koligatif Larutan; (2) mengevaluasi hasil belajar dalam hal pengetahuan dan keterampilan di kalangan siswa kelas XI SMA Negeri 1 Titehena setelah menggunakan LKPD berbasis PBL; dan (3) menganalisis tanggapan siswa terhadap media LKPD yang dikembangkan.

Abstract

Pengelolaan sampah organik di lingkungan sekolah masih menjadi tantangan yang belum tertangani secara optimal, termasuk di SMA N Harekakae, Kabupaten Malaka, Nusa Tenggara Timur. Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan literasi lingkungan siswa, membangun keterampilan pengolahan sampah organik menjadi Pupuk Organik Cair (POC), serta mengintegrasikan kegiatan tersebut ke dalam Projek Penguatan Profil Pelajar Pancasila (P5) bertema Gaya Hidup Berkelanjutan. Metode yang digunakan adalah pendekatan participatory action yang mencakup empat tahap, yaitu persiapan dan koordinasi dengan mitra, sosialisasi, pelatihan dan pendampingan pembuatan POC dan kompos, serta panen POC dan evaluasi. Sosialisasi dilaksanakan secara interaktif melalui presentasi visual dan diskusi, sedangkan pelatihan dilakukan melalui demonstrasi dan praktik langsung pembuatan POC berbahan organik kantin sekolah dengan bioaktivator EM4. Hasil kegiatan menunjukkan peningkatan pengetahuan peserta yang signifikan, tercermin dari kenaikan rata-rata skor pre-test ke post-test sebesar 68,1%, dari 28,4% menjadi 96,5%. Tingkat kepuasan peserta mencapai 83%, dan seluruh aspek kesesuaian kegiatan dengan kebutuhan implementasi P5 berada di atas 80%. Kegiatan ini berhasil mengintegrasikan pengolahan sampah organik ke dalam P5 sekaligus menumbuhkan semangat kewirausahaan hijau di kalangan siswa.Abstrak ditulis secara ringkas dan faktual menggunakan huruf Tahoma, ukuran 9pt dengan panjang teks antara 150-200 kata.
