Abstract

This study evaluate the performance of nanofiltration (NF) membrane system and pre-treatment coagulation and floculation in the treatment of palm oil mill effluent (POME) by varying the effect of concentration of coagulant, slow mixing speed, and transmembrane pressure. The process of coagulation-flocculation used aluminium sulfate with variation of concentration 3.5 g/l; 4.0 g/l; 4.5 g/l. The process completed with rapid stirring 200 rpm for 5 minutes and variation of slow stirring 65 rpm; 85 rpm; 105 rpm for 15 minutes, settling time for 30 minutes. Nanofiltration membrane processes conducted during the 60-minute operation on transmembrane pressure variation 6.5 bar; 7.5 bar; and 8.5 bar. In each treatment process, wastewater quality tests were carried out with biochemical oxygen demand (BOD) test parameters, chemical oxygen demand (COD), and total suspended solid (TSS). In addition, an analysis of permeate fluxes and the percentage of NF membrane rejection was also carried out. The research results obtained the best concentration of aluminium sulfate at 4.5 g/L and slow mixing speed 65 rpm i.e. of 71.04%; 75.49%; and 90.43% respectively for BOD, COD, and TSS. The research results obtained the value of most NF membrane high selectivity at transmembrane pressure 8.5 bar i.e. of 84.66%; 86.76%; and 94.95% respectively for BOD, COD, and TSS with a flux value of 6.32 L/m2.hours.Keywords: Aluminium Sulfate, Coagulation, Flocculation, Nanofiltration, Palm Oil Mill Effluent

Abstract

Peat water has a low pH (3-5), brown (124-850 PtCo), and contains many organic substances that do not meet the standards of water quality requirements as Permenkes No.416/MENKES/PER/IX/1990. Therefore it is necessary for processing methods to eliminate pollutants contained in the peat water so it can be used according to quality standards, either by adsorption. Adsorbent used in this research is compost. Compost carbonized by variation of 30, 60 and 90 minutes, which is activated in physics at a temperature of 500 ° C. Adsorbent mass variations as much as 1, 2, 3, 4 and 5 grams with a stirring speed of 100 rpm for 120 minutes. Characteristics of activated carbon in the form of compost moisture content, ash content, volatile and fixed carbon content obtained the best results in 60 minutes with a water content of 4.00%; ash content 0.99% volatile 1.57% and fixed carbon 97.44%. The efficiency of color reduction was measured using a UV-VIS spectrophotometer. The result showed that the highest efficiency was 81,63% at carbonization time 60 minutes with mass 5 gram and the lowest efficiency value was 66,57% at carbonization time 30 minutes with mass 1 gram.Keywords : Adsorbent, activated carbon, compost, color.

Abstract

Sago bark waste (uyung) is abundant in Sungai Tohor Village, Kepulauan Meranti Regency, but has not been optimally utilized, causing environmental problems. Research conducted by the Environmental Engineering Study Program, Universitas Riau, has developed charcoal briquettes from sago bark, which are then implemented in the community to provide real impacts on improving quality of life and supporting the impactful campus program. This community service aims to assist local communities and businesses in improving the quality of sago bark charcoal briquettes to meet export standards and support village energy transition. The methods included counseling, Focus Group Discussions (FGD), technical training on briquette production, quality testing, and business management strengthening. The FGD held in Selat Panjang (September 18–21, 2025) involved 20 participants from strategic partners including the Meranti Regency Department of Industry and Trade, Department of Housing and Environment, Sago Center, Village-Owned Enterprises (BUMDes), and export practitioners from Ecotohor Solution. The results showed increased community understanding of export briquette standards with characteristics such as high calorific value, low moisture content, good density, and stable combustion. This technology implementation strengthens the potential of sago bark charcoal briquettes as a village flagship product for the global market while promoting energy transition and sustainable economy.

Abstract

Program pengabdian masyarakat ini dilaksanakan di Desa Sagu Sungai Tohor, Kabupaten Kepulauan Meranti, yang dikenal sebagai salah satu sentra industri sagu terbesar di Riau. Aktivitas pengolahan sagu menghasilkan limbah kulit batang sagu dalam jumlah besar, yang memiliki potensi tinggi untuk dikonversi menjadi briket arang bernilai ekonomi. Kegiatan pendampingan ini bertujuan untuk meningkatkan kualitas briket arang kulit batang sagu agar memenuhi standar komoditas ekspor serta memperkuat pemasaran produk melalui pendekatan teknologi dan manajemen usaha. Pendampingan mencakup: pelatihan proses karbonisasi dan pembriketan kulit batang sagu, peningkatan mutu produk sesuai standar SNI dan kebutuhan pasar ekspor, serta pelatihan strategi pemasaran digital dan jaringan distribusi. Sebelum kegiatan, produksi briket dilakukan secara konvensional dan belum memenuhi standar kualitas internasional. Melalui program ini, UMKM lokal difasilitasi untuk meningkatkan kapasitas teknis, kualitas produk, serta kompetensi pemasaran sehingga briket arang sagu berpotensi menjadi komoditas ekspor unggulan daerah dan mampu meningkatkan perekonomian masyarakat. Kegiatan pengabdian ini dilaksanakan dari bulan Agustus hingga akhir November 2025.. Melalui kegiatan ini diharapkan masyarakat dapat memanfaatkan arang kulit batang sagu menjadi biopelet sebagai bahan bakar dirumah tangga atau skala lebih besar di skala industri pengganti bahan bakar di boiler . Diharapkan melalui kegiatan ini dapat menjadi sumber pendapatan yang dapat meningkatkan kesejahteraan masyarakat disamping dapat mengatasi permasalahan dari limbah kulit batang sagu yang mencemari lingkungan
