Abstract

One of the most hazardous environmental pollutants that existed is silver liquid waste produced in photographic processing. Some types of water plants are believed to be able to absorb organic, inorganic, and other chemical compounds contained in liquid waste, water spinach (Ipoemea aquatica) being one of them. This study aimed to determine the effectiveness of water spinach (Ipoemea aquatica) in controlling silver liquid waste (Ag) contamination in water. The research design used was randomized block design. The data was then analyzed using a particular formula. The results of the study showed that after 15 days of treatment, water spinach (Ipoemea aquatica) was found to be effective in significantly reducing temperature and level of silver (Ag), but not the pH of the waste liquid. The highest effectiveness was observed when fifteen water spinach (Ipoemea aquatica) plants were used; temperature fell 17.90% (1.60% from the control value; and the level of silver (Ag) fell 5.30%

Abstract

Kementerian Lingkungan Hidup dan Kehutanan merilis data terbaru berkaitan volume sampah yang ada di negara Indonesia pada tahun 2021 tercatat 18,2 juta ton/tahun dari 154 Kabupaten/kota se-Indonesia. Sedangkan sampah yang mampu dikelola dengan baik hanya sebanyak 13,2 juta ton/tahun atau setara dengan 72,95%. Hal ini dapat terjadi dikarenakan masih terbatasnya daya tampung tempat pembuangan sampah baik Tempat Pemrosesan Akhir (TPA) maupun Tempat Penampungan Sementara (TPS), hingga minimnya standar dalam pengelolaan sampah yang sudah diterapkan. Dari kondisi yang telah terurai diatas, untuk pengelolaan sampah bukan hanya tugas dari pemerintah saja, melainkan ada peran serta dari masyarakat maupun pelaku yang harus bertanggungjawab agar lingkungan tetap bersih dan sehat. Untuk mengatasi masalah sampah, maka pemerintah melalui Dinas Lingkungan Hidup Perumahan Rakyat dan Pemukiman sejak bulan September 2019 mulai mencanangkan konsep bank sampah. Pengelolaan bank sampah harus dilakukan secara kreatif dan inovatif dengan mendampingkan teknologi informasi yang berkelanjutan untuk menunjang kegiatan pengelolaan dana nasabah bank sampah dengan baik dan transparan. Tim PkM Fakultas Teknik Universitas Satya Negara Indonesia melakukan sosialisasi dan penyuluhan kepada mitra pengelola bank sampah di wilayah Kelurahan Grogol Selatan berkaitan dengan penggunaan aplikasi digitalisasi bank sampah. Hasil responbility dari para peserta kegiatan sosialisasi ini bermanfaat untuk menunjang aktivitas peserta dengan direpresentasikan sebesar 83,33%.

Abstract

A coal-fired power plant is a type of power generation facility that uses coal as its primary fuel. During the power production process, both B3 (hazardous) and non-B3 waste are generated. One of the main types of waste produced is fly ash and bottom ash (FABA). When FABA is allowed to accumulate over a long period, it can cause environmental problems such as air and water pollution and a decline in ecosystem quality. The results of the FABA characteristic test using the Toxicity Characteristic Leaching Procedure (TCLP) showed that none of the tested parameters exceeded the quality standards, particularly for heavy metals, in accordance with Government Regulation Number 22 of 2021 concerning the Implementation of Environmental Protection and Management. This study examines the use of FABA as a growing medium for chili plants (Capsicum frutescens). The research employed visual observation and soil analyzer methods. Visual observations focused on plant growth indicators, including plant height and number of leaves, while soil analyzer was used to measure pH, moisture, and temperature. The treatment consisting of 75% FABA and 25% soil was found to be the optimal composition, producing the highest plant height and number of leaves up to the 10th week of observation. Furthermore, soil analyzer revealed that this combination is suitabie as a planting medium.

Abstract

Game Mobile Legends: Bang Bang menghasilkan jutaan ulasan pengguna yang mengandung sentimen berharga bagi pengembang, namun analisisnya terkendala oleh volume data yang besar serta penggunaan bahasa informal yang kompleks. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem analisis sentimen otomatis menggunakan model deep learning Transformers BERT untuk mengklasifikasikan ulasan pengguna ke dalam kategori positif, negatif, dan netral. Metode penelitian mencakup pengumpulan 548.250 data ulasan dari Kaggle, pra-pemrosesan teks untuk menangani noise, dan pelatihan model IndoBERT melalui teknik fine-tuning. Kinerja model dievaluasi menggunakan metrik akurasi, presisi, recall, dan F1-score. Hasil penelitian menunjukkan bahwa model IndoBERT yang telah disempurnakan (fine-tuned) mencapai akurasi 83.2%, sebuah peningkatan signifikan sebesar +62.8% dibandingkan model dasarnya (pre-trained) yang hanya mencapai 20.4%. Keberhasilan ini membuktikan bahwa proses fine-tuning secara efektif mengadaptasi model untuk memahami jargon dan konteks unik dalam ulasan game. Seluruh alur penelitian diimplementasikan dalam sebuah aplikasi web interaktif menggunakan Streamlit sebagai bukti konsep dan alat visualisasi hasil analisis.
