Abstract

The palm oil industry produces POME (Palm Oil Mill Effluent) liquid waste. POME is generally brownish, has an odor, and contains dissolved and suspended solids in the form of colloids and oil residue with a high Chemical Oxygen Demand (COD) content. Currently, the POME processing system still uses a conventional system known as the open pond system. This research aims to reduce the burden of organic materials related to removing COD levels, and color. It can solve the technical and operational obstacles of conventional processing systems. One of the extensive efforts to process POME is to develop Fenton-based photocatalytic technology, namely the Fenton-TiO2-UV method. Photocatalytic technology has several general processes involving semiconductor photocatalysts such as TiO2 and photon (UV) energy sources. In this study, the Fenton-TiO2-UV method was used with variations in the Fenton molar ratio of 1:100, 1:200, 1:300 (v/v), reaction times of 30, 60, and 90 minutes with TiO2 concentration 0.6% and uses 2 UV lamps (15 watts). This study achieved the maximum color degradation percentage at a Fenton molar ratio of 1:100 with a reaction time of 30 minutes, namely 95.28%. Meanwhile, the maximum COD degradation percentage was achieved at a Fenton molar ratio of 1:100 with a reaction time of 90 minutes, namely 98.88%.

Abstract

Pemilahan sampah rumah tangga di sumbernya pada Kelurahan Rajabasa Jaya, Kota Bandar Lampung, masih tergolong rendah, sehingga diperlukan intervensi edukatif yang sejalan dengan Permen LHK No. 14 Tahun 2021 serta kebijakan 3R (Reduce, Reuse, Recycle). Kegiatan bertujuan memperkuat pengetahuan, sikap, dan keterampilan warga dalam pemilahan sampah rumah tangga. Kegiatan dilaksanakan di Bulan Agustus 2025 di Kelurahan Rajabasa Jaya. Metodologi menggunakan desain sebelum–setelah pada satu kelompok (20 peserta) melalui penyuluhan, demonstrasi pemilahan tiga wadah (organik, anorganik, B3), latihan langsung/simulasi, serta evaluasi dengan kuesioner 10 butir (jawaban positif/negatif) dan analisis deskriptif. Hasil penelitian menunjukkan bahwa persentase keseluruhan jawaban positif sebelum perlakuan sebesar 6,5 persen, sedangkan setelah perlakuan meningkat menjadi 100 persen. Berdasarkan hasil tersebut, pelatihan ini menjadi langkah yang efektif untuk penguatan kapasitas rumah tangga dalam pemilahan sampah dan dapat menjadi dasar implementasi program 3R berbasis komunitas di Rajabasa Jaya.

Abstract

The issues of freshwater pollutions and the high demand of clean freshwater for daily human activities have forced developing countries such as Malaysia to continuously monitor the quality of the freshwater. The present study objective is to present the trend of water quality status in the Kelantan River downstream, Peninsular Malaysia from 2005 to 2018. Water samples were collected during dry and monsoon seasons from a sampling station located at downstream of the Kelantan River. Water quality parameters such as temperature, pH and dissolved oxygen (DO) were measured in situ while other parameters were analysed in the laboratory based on retrieved water samples. Water quality status was determined based on National Water Quality Standard (NWQS) for River in Malaysia by calculating the water quality index (WQI) according to the concentration of six water quality parameters involving pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (TSS) and Ammonia Nitrogen (AN). The results showed that Kelantan River had good water quality during the dry season classified in Class II at 2005. The water quality was found to be slightly lower during the monsoon season in year 2006. In addition, increasing the number of construction, human activities in the land use areas, land use changes and the sewage water from domestic, industrial, wet market and food outlets in the Kelantan State have declined the water quality in Kelantan River from Class II (in 2005) to Class III (in 2010 and 2011) and to become Class IV in 2017 to 2018. The results of the present study are expected to give valuable information for the water managers in order to deal with better strategies in controlling the quality of freshwater at the Kelantan River and minimize the incidence of pollution-oriented problems, thus the water can be utilized for various water uses with appropriate quality.

Abstract

SMA Negeri 5 Bandar Lampung is located in a strategic yet disaster-prone area, facing risks such as floods, earthquakes, and fires. The school did not have a structured evacuation route system or evacuation maps displayed in strategic areas, leaving the school community without clear visual guidance for evacuation routes and assembly points during emergencies. This community service activity aimed to develop evacuation route maps based on the actual spatial conditions of the school to improve preparedness. The methods included field observation, manual measurement, visual documentation, and digital mapping using AutoCAD, with design validation involving school stakeholders. The activity produced a proportional digital evacuation map showing routes from all strategic areas to three designated assembly points. Before the implementation, only 16.7% of evacuation-supporting elements were available; after installation and dissemination, the preparedness index improved significantly from an average of 22.7% to 76.7%. The map is clear, easy to understand, and serves as an essential visual reference to support the Disaster-Safe School program. The development of this evacuation route map has improved the structural preparedness of the school and provides a technical foundation for future disaster drills and training.
