Abstract

Bromo is one of Indonesia’s premier tourist destinations, renowned for its unique biodiversity, including Edelweiss (Anaphalis javanica), a symbolic flower of mountainous ecosystems. However, increasing tourism activities and human interference have threatened the conservation of Edelweiss habitats. To address this challenge, faculty members from the Faculty of Engineering and Science, Universitas Pembangunan Nasional "Veteran" Jawa Timur, in collaboration with the local community of Bromo and international universities, conducted an Edelweiss planting program on September 26, 2024. This initiative was part of the Adjunct Professor program and the International Conference on Science and Technology (ICST) 2024. The program achieved a seedling adaptation success rate of 85%, contributing to improved soil stability in the planting areas. Beyond ecological impacts, the initiative successfully raised environmental awareness and fostered active local community participation in conservation. The collaboration among academics, the local community, and international partners highlighted the importance of multi-stakeholder approaches in environmental preservation. Despite challenges such as unpredictable weather and the need for long-term monitoring, the program serves as a model for community-based conservation initiatives in other sensitive ecosystems.

Abstract

Slaughterhouse wastewater contains high levels of organic matter and nitrogen, which can potentially pollute the environment if not properly treated. This study aims to analyze the effectiveness of the Moving Bed Biofilm Reactor (MBBR) system with intermittent aeration using pumice stone media in reducing Chemical Oxygen Demand (COD) and ammonia (NH₃-N) concentrations. The tested variables included media filling ratios (25%, 35%, and 45%) and hydraulic retention times (4, 6, and 8 hours) with balanced oxic–anoxic cycles. The results showed that increasing the media ratio and retention time significantly improved pollutant removal efficiency. The best performance was achieved with 45% media and an 8-hour retention time, resulting in COD and NH₃-N removal efficiencies of 87% and 82.8%, respectively. The pumice stone media effectively supported biofilm growth, which played a key role in the nitrification–denitrification processes. The intermittent MBBR technology with pumice media proved to be efficient, economical, and environmentally friendly for the treatment of slaughterhouse wastewater.

Abstract

Air sumur merupakan salah satu sumber air tanah yang banyak dimanfaatkan, namun umumnya mengandung mineral terlarut dalam konsentrasi tinggi seperti besi (Fe) yang dapat menurunkan kualitas air. Penelitian ini mengkaji upaya peningkatan kualitas air sumur melalui kombinasi proses aerasi dan adsorpsi. Aerasi dilakukan menggunakan  diffuser berukuran 8 inch dan 10 inch, sedangkan proses adsorpsi menggunakan sistem kolom kontinyu dengan adsorben Ampas tebu, kulit pisang, dan campuran keduanya.Tujuan penelitian ini adalah menganalisis efektivitas variasi aerasi terhadap penurunan kadar Fe. Menganalisis kinerja variasi adsorben pada kolom kontinyu, serta menganalisis efektivitas kombinasi kedua proses tersebut. Hasil penelitian menunjukkan bahwa aerasi sangat efektif dalam menurunkan Fe dengan persen removal 91,4 - 94,1%,. Pada proses adsorpsi, kolom campuran menunjukkan kinerja terbaik dengan persen removal Fe sebesar 86,7 - 87,1%. Secara keseluruhan, kombinasi aerasi  diffuser diikuti dengan Adsorpsi Kolom Campuran merupakan kombinasi 2 proses yang saling terhubung. Hal ini akan menghasilkan efisiensi penyisihan total yang sangat tinggi,serta lebih mempermudah dalam proses adsorpsi dan menghemat penggunaan media adsorben dikarenakan sebelum masuk kedalam proses adsropsi dilakukan proses aerasi terlebih dahulu.
