Abstract

The Community Service Team of the Faculty of Engineering of Riau University together with students of the Riau University 2022 Kukerta team in Batu Belah Village, Kampar District provided assistance and demonstrations on how to make eco-enzyme solution from organic waste as a multifunctional solution. The eco-enzyme solution is a liquid resulting from the fermentation of organic waste in the form of fruit and vegetable waste which is added brown sugar and water in a ratio of 3:1:10 for 90 days. The purpose of this community service activity was to provide knowledge to the community and housewives group of Batu Belah Village, Kampar District to utilize organic waste into eco-enzyme solution and the benefits of eco-enzyme for various functions. In the implementation of community service activities, several stages were carried out including the stage of meeting with village officials and recording enthusiasts who wanted to take part in the training, then from the results of the participant data, the socialization stage and demonstration of training materials for making eco-enzyme solutions. The last stage to see the achievement of the training results is monitoring the level of understanding and enthusiasm of the participants. The results of the service showed that the Batu Belah Village community was very enthusiastic about participating in the socialization of making eco-enzyme from organic waste and was willing to practice it in their respective homes with an understanding level of 93.3%.

Abstract

Functioning industrial waste as raw material or as a product is an achievement that will continue to be optimized, especially in industries where the amount of waste is significant. Pulp and paper mills produce waste in the form of solid, sludge, liquid and gas. The objective of this research is to extract the element ferrum contained in one of the solid wastes in pulp and paper mills. By using two fatty amine extractor, lauryl amine and stearyl amine with ethanol and n-hexane as solvents. The results showed that the use of stearyl amine as an extractor and n-hexane as a solvent with operating conditions of 4 hours and a dose of 5 grams gave the best results with an extraction yield of 10,964 mg/kg.

Abstract

Proses pembakaran batu bara menghasilkan emisi berupa gas SO2, NO2, CO, CO2, volatile hydrocarbon (VHC), suspended particulate matter (SPM), serta residu padat berupa abu boiler. Abu boiler mengandung berbagai logam berat beracun, diantaranya tembaga (Cu), kobalt (Co), kromium (Cr), cadmium (Cd) dan timbal (Pb). Penelitian ini bertujuan untuk menentukan efisiensi reduksi logam berat Cu, Co, Cr, Pb, dan total dengan melakukan ekstraksi menggunakan pelarut kimia NaOH dan mengubah logam transisi menjadi kompleks dengan Ethylene diamine tetraacetic acid (EDTA) pada rasio EDTA: abu boiler sebesar 1:2, 1:1, 2:1; durasi pengadukan sebesar 2 dan 4 jam; serta suhu ekstraksi sebesar 25 dan 60 oC. Analisis Inductively Coupled Plasma (ICP) dilakukan untuk mengetahui penurunan kadar logam berat dari ekstrak abu boiler. Hasil penelitian menunjukkan bahwa kondisi ekstraksi berupa rasio EDTA: abu boiler sebesar 2:1, durasi pengadukan sebesar 4 jam, dan suhu ekstraksi sebesar 60 oC dapat menghasilkan persentase penurunan kadar logam berat total tertinggi yang mencapai 77,2% dengan persentase penurunan kadar Co, Cr, Cu, dan Pb secara berturut-turut sebesar 75,4%, 77,9%, 74,5%, dan 81,9%. Penelitian ini diharapkan dapat menjadi rekomendasi bagi penelitian selanjutnya dalam mengeksplor potensi pemanfaatan abu boiler yaitu sebagai bahan campuran aspal, pembuatan batako, dan sebagainya.

Abstract

Peningkatan produksi nanas di Indonesia menghasilkan limbah kulit nanas yang melimpah, namun belum dimanfaatkan secara optimal. Sementara itu, kebutuhan akan pupuk organik yang ramah lingkungan terus meningkat seiring dengan tren pertanian berkelanjutan. Penelitian ini mengkaji pembuatan pupuk organik cair berkualitas tinggi dari limbah kulit nanas melalui proses fermentasi. Tujuannya adalah mengevaluasi kualitas pupuk berdasarkan rasio C/N dan menganalisis pengaruh variasi nutrisi, konsentrasi EM-4, serta waktu fermentasi terhadap kandungan unsur hara. Metode yang digunakan melibatkan fermentasi 100 gram kulit nanas dalam 200 ml akuades dengan variasi rasio EM-4 (4, 8, 12 ml), jenis nutrisi (kombinasi gula merah, air kelapa, air cucian beras), dan waktu fermentasi (5, 10, 15, 20 hari). Hasil terbaik diperoleh pada kombinasi nutrisi gula merah:air kelapa:air cucian beras, konsentrasi EM-4 12%, dan waktu fermentasi 20 hari. Pupuk ini mengandung 0,28% nitrogen, 0,14% fosfor, 0,2% kalium, rasio C/N 1:10,06, 13,7 ppm besi, dan 8,71 ppm boron. Penelitian ini menunjukkan bahwa peningkatan waktu fermentasi dan konsentrasi EM-4 mengoptimalkan dekomposisi, menghasilkan pupuk organik cair dengan kandungan nutrisi yang lebih baik. Temuan ini membuka peluang pemanfaatan limbah kulit nanas sebagai sumber pupuk organik cair yang efektif dan ramah lingkungan, sekaligus menawarkan solusi untuk mengurangi limbah pertaniaan.

Abstract

Desa Batu Belah, Kecamatan Kampar, Riau, mengembangkan strategi pencegahan banjir berkelanjutan melalui penanaman Artocarpus integer (cempedak). Tanaman ini dipilih karena akarnya yang kuat dapat menyerap air dan mencegah erosi. Selain itu, cempedak juga berpotensi sebagai sumber ekonomi lokal melalui pengolahan produk makanan. Kegiatan ini dilakukan secara gotong royong, memperkuat kebersamaan masyarakat dan meningkatkan kesadaran lingkungan. Hasilnya adalah peningkatan ketahanan lingkungan dan potensi ekonomi masyarakat. Strategi ini menunjukkan bahwa penanaman Artocarpus integer dapat menjadi solusi efektif untuk mengurangi risiko banjir dan meningkatkan kualitas hidup masyarakat. Dengan demikian, desa ini menjadi model bagi pengembangan masyarakat yang berkelanjutan dan peduli lingkungan, serta meningkatkan keindahan dan keamanan lingkungan.

Abstract

Environmental awareness and concern for cleanliness remain common challenges, not only in urban areas but also in rural communities. In Pangkalan Bunut Village, the issue of poor waste management persists, largely due to limited community awareness and the lack of adequate waste disposal facilities. To address this problem, our Community Service Team implemented a program to provide waste bins in the Pangkalan Bunut Market. This initiative aimed to encourage proper waste disposal practices, improve environmental awareness, and promote a clean and healthy environment. The program produced several positive outcomes: (1) increasing community understanding of the importance of waste management and environmental care; (2) providing accessible waste bins at the market to support cleaner surroundings; and (3) fostering behavioral change, as residents became more aware of the importance of proper waste disposal. This initiative is expected to serve as a model for sustaining cleanliness and environmental health in Pangkalan Bunut Village.

Abstract

The synthesis of the ZnO-biochar composite from palm kernel shell biomass waste has been accomplished through the utilization of thesolvothermal method, yielding a satisfactory outcome. The resulting composite, a combination of ZnO and biochar, has been utilized in the degradation of methylene blue waste compounds. The objective of this research is to synthesize ZnO-biochar composites from palm shells, and to determine the optimal solvothermal temperature and duration. This research was initiated with the preparation of palm shells into biochar. Subsequently, the ZnO-biochar composite was synthesized with variable solvothermal temperatures and solvothermal times. The ZnO-biochar composite was characterized using analytical techniques including SEM-EDX, FT-IR, XRD, BET and UV-vis DRS. The most effective degradation of methylene blue was exhibited by the ZnO-biochar composite sample synthesized at a solvothermal temperature of 180 ̊C and a solvothermal time of 10 hours, achieving a degradation of 88.29%. The enhanced photodegradation performance of this composite sample is attributed to its high surface area, capacity for visible light absorption, and the dimensions of the active crystals, which can account for the high performance of the ZnO-biochar composite for photocatalytic degradation.
