Abstract

Perumahan Griya Indah Blok D No.344 Kel.Penyengat Rendah Kec.Telanaipura merupakan lokasi yang berdekatan dengan pasar rakyat. Semakin tingginya aktivitas masyarakat di pasar dan sekitarnya menyebabkan semakin tinggi pula jumlah sampah yang dihasilkan. Sampah itu sendiri tergolong ke dalam dua jenis yaitu sampah yang dapat diuraikan dan sampah yang tidak dapat diuraikan. Jenis sampah yang tidak dapat diuraikan ini seperti sampah plastik dari botol air minuman dan plastik kemasan pembungkus makanan. Sampah plastik tidak termasuk jenis sampah yang berbahaya, namun apabila dibiarkan secara terus-menerus maka akan menumpuk dan menjadi limbah padatan. Sementara masyarakat sekitar belum memiliki pengetahuan dalam penanganan dan pengolahan sampah plastik yang baik.Tim Pengabdian masyarakat memberikan sebuah solusi penanganan sampah plastik yakni dengan metode pirolisis. Metode ini mampu mengubah sampah plastik menjadi bahan bakar cair dan hasil sampingnya dapat dijadikan sebagai bahan pembuatan paving block. Kegiatan pengabdian ini diharapkan dapat menjawab permasalahan lingkungan yang ada di masyarakat dan hasil yang diperoleh berupa produk dan menambah nilai jual bagi masyarakat.

Abstract

Mangrove merupakan tanaman agroindustry yang memiliki potensi untuk dikembangkan. Tanjung Solok merupakan daerah pesisir yang dikelilingi oleh tanaman mangorove dimana salah satu jenisnya adalah jeruju. Masyarakat belum mengetahui bahwa jeruju memiliki banyak manfaat diantaranya pada bidang kesehatan sebagai antioksidan, antiinflmasi, antijamur dan antikanker. Selain itu jeruju juga dapat diolah menjadi berbagai produk pangan. Ekstrak daun jeruju telah diteliti memiliki kandungan senyawa golongan flavonoid, polifenol, kumarin, alkaloid, saponin dan terpenoid. Adanya potensi antioksidan dari daun jeruju, membuka peluang dengan pemanfaatannya sebagai teh herbal. Ekstrak daun jeruju juga dapat digunakan sebagai bahan pada pembuatan kerupuk. Melihat adanya potensi pengembangan produk pangan berbahan dasar daun jeruju, maka perlu dilakukan pendampingan kepada masyarakat dalam melakukan pengolahan daun jeruju menjadi produk pangan fungsional. Berdasarkan Evaluasi kegiatan PPM, peningkatan pemahaman dan keterampilan Masyarakat meningkat sebesar 80-87%.

Abstract

Ceiba pentandra (Kapok) is a tropical plant belonging to the Malvales that contain palm oil. Naturally, Pure Plant Oil (PPO) can be used as a renewable energy source that is a promising energy alternative instead of fossil. Somehow, one of the effects of the quality of Pure Plant Oil (PPO) is the presence of unsaturated bonds and the presence of oxygen. The most appropriate method to overcome these problems is hydrodeoxygenation using a batch system autoclave reactor. In the present work, we synthesized of Green Diesel using hydrodeoxygenation and NiMo/-Al2O3 catalyst to saturate double bonds and remove oxygen. The yield of pure plant oil was 42.77-74.72% while the yield of green diesel at pressure conditions of 30 and 50 bar and at temperatures of 300, 350 and 400C produced 76.73 94.06%. Then, the best condition for the hydrodeoxygenation reaction for the biggest yield is at a pressure of 50 bar at 350C. The results of the characterization of gas products using GC-TCD showed the composition of gases H2, O2, CO, CH4, and CO2. Whereas for green diesel liquid products, pure plant oil, and kapok seed oil were analyzed using GC-MS obtained hydrocarbon compounds with interval C10-C20. Quality analysis of kapok seed oil, pure plant oil, and green diesel has been in accordance with quality standards except for FFA and viscosity.

Abstract

ABSTRAKProvinsi Jambi merupakan salah satu provinsi di wilayah Sumatera yang memiliki potensi sumberdaya alam yang cukup melimpah. Tanaman kelapa banyak dihasilkan di Provinsi Jambi, terutama di Kabupaten Tanjung Jabung Barat. Kelapa mempunyai peluang yang sangat besar untuk pengembangan agribisnis dari hulu maupun hilir. Peluang yang besar ini dapat dimanfaatkan untuk menjadikan produk kelapa dengan meningkatkan nilai tambah (added value) produk kelapa menjadi Virgin Coconut Oil (VCO). Pengolahan produk kelapa menggunakan teknologi yang murah dan efisien, sehingga menghasilkan VCO yang sesuai dengan standar mutu. Cara kerja alat pembuat VCO yang dibuat dengan teknologi tersebut dapat digunakan di kalangan masyarakat, sehingga hasil desain alat teknologi pembuatan VCO dapat menghasilkan produk VCO yang sesuai dengan standard dan juga dapat meningkatkan kesejahteraan ekonomi di Desa Pembengis Kecamatan Bram Itam Kabupaten Tanjung Jabung Barat Provinsi Jambi.Kata kunci : added value, kelapa, produk, teknologi, vcoABSTRACTJambi Province is one of the provinces in Sumatra which has abundant natural resource potential.

Abstract

Rhodamine B is an organic dye commonly used in the textile industry, but it is toxic. Therefore, a photodegradation method using Fe3O4/activated carbon (AC)/ZnO nanocomposite is necessary to address environmental issues caused by rhodamine B. The Fe3O4/AC/ZnO nanocomposite has been successfully synthesized using the sonication method. Iron sand is used as a source of magnetite (Fe3O4), coconut shells as a source of activated carbon, and Zinc nitrate as a source of ZnO. XRF results show that the Fe content in iron sand is 74.10%. The ratio of Fe3O4 addition used in Fe3O4/AC/ZnO nanocomposite is 0:1:1; 1:1:1; 2:1:1; 3:1:1; 4:1:1. XRD characterization shows that the 1:1:1 ratio of Fe3O4/AC/ZnO nanocomposite has the smallest crystal size of 48.17 nm. The addition ratio of Fe3O4 does not affect the structure of the formed Fe3O4/AC/ZnO nanocomposite. Fe3O4/AC/ZnO nanocomposite is formed at 2theta 30.23°; 35.60°; 57.11°; and 62.83° for Fe3O4, peak broadening at 26.72° and ~44.71 for AC, and 31.82°; 34.47°; 36.30°; 47.59°; 56.63°; 62.89° and 67.98° for ZnO. SEM results show particle sizes of 57.95 nm for ZnO and 42.74 nm for Fe3O4/AC/ZnO 1:1:1 nanocomposite. VSM showed saturation magnetism of 4.41 emu/g for Fe3O4/AC/ZnO 1:1:1 nanocomposite and 28.8 emu/g for Fe3O4. The photocatalytic test showed that the Fe3O4/AC/ZnO 1:1:1 nanocomposite had the best % degradation of rhodamine B, at 96.1%, under sunlight.

Abstract

The COVID-19 pandemic has increased online shopping and food delivery, causing a surge in single-use plastic waste and has become a habit to this day along with the rapid development of digital technology. Dream Central Waste Bank (BSI Dream) in Wijaya Pura Village collects 3 tons of waste monthly but lacked advanced plastic processing technology. This community service initiative aimed to implement a pyrolysis reactor to convert plastic waste into fuel oil and paving blocks, thereby enhancing economic value while promoting environmental sustainability. The activity stages included partner coordination and surveys, reactor performance upgrades, operational training, and evaluation. This activity involved five partners representing the Wijaya Pura Village community.  The reactor successfully produced fuel oil (density: 0.848–0.912 g/mL) and residues suitable for paving block production. The outcome of this initiative demonstrated improved skills among partners, the creation of marketable products and increased community income opportunities. Furthermore, the activity fostered greater awareness of the importance of sustainable waste management and supported the application of circular economy principles.

Abstract

Mendalo Indah Village has great potential for trade because of its strategic location near two major universities in Jambi Province, namely Jambi University and UIN Sultan Thaha Jambi. Students in this area have a strong preference for instant food and beverages as a result of their busy academic and practicum schedules. The urgency of this community service activity lies in the need for instant but natural health supplements among students, as well as the need for housewives to gain additional income. The training on the production of “Japan Instan” in Mendalo Indah Village aims to empower the community, especially housewives and unemployed women, by developing creative economic activities through innovative and marketable prod ucts. Ginger was chosen as the main ingredient because of its well-known health benefits, such as relieving headaches, preventing colds, improving digestion and increasing appetite (stimulant). Ginger is also a commonly found local plant. The training covered the processing of ingredients, packaging and marketing strategies. Additionally, pandan leaves were utilized as an innovation to enhance the flavor and aroma, resulting in a healthy instant beverage product
