Abstract

Desa Paduan Rajawali merupakan salah satu sentra penghasil Rosella di Kabupaten Tulang Bawang. Produk yang dihasilkan hanya ditangani dengan cara yang sederhana. Akibatnya produk mengalami kendala untuk dapat dipasarkan secara global. Selain itu, pemasaran produk Desa hanya sebatas pameran produk yang di adakan pada tingkat lokal dan provinsi sehingga kegiatan yang dilakukan oleh Kelompok Wanita Kreatif Rosella ini tidak signifikan meningkatkan pendapatan desa. Pengabdian ini bertujuan untuk meningkatkan produktifitas produk olahan Rosella melalui penambahan varian produk Rosella dan pengemasan produk. Metode yang digunakan untuk mendukung kegiatan ini ialah dengan memberikan edukasi dan pendampingan tentang pengolahan produk-produk hasil pertanian khususnya Rosella. Materi kegiatan pengabdian sangat sesuai dengan kebutuhan mitra dan pelaksanaan kegiatan secara berkelanjutan yang ditunjukkan dengan 80% peserta memberikan penilaian sangat setuju (SS) dan 60% peserta menyatakan bahwa peralatan yang digunakan sesuai kebutuhan dan mudah untuk digunakan. Mitra juga menyambut dengan baik disain logo yang diberikan, saran pengemasan, tambahan produk, serta pemasaran online yang telah dibuatkan. Mitra sangat antusias terhadap kegiatan ini dan berharap dilakukan pendampingan serupa Kata kunci: diversifikasi, produk Rosella, Rosella

Abstract

Increasing of ambient temperature due to global warming has a direct impact on increasing the room temperature. Heat from surrounding is transferred to building wall and room. By installing the Vertical Greenery System (VGS) on the building wall, it can be an alternative for heat absorber and eco-friendly indicator. The aims of this study are to determine the temperature that can be reduced by VGS type Green Façade (GF) and  achieve the energy consumption reduction because of GF installation.  GF is installed on the building wall, property of Mining Engineering Department, Sriwijaya University, to measure its temperature, then compare it with the  temperature on control wall. The results showed that the GF can reduce the room temperature up to 1,2oC, compared to the control wall and the average is 0,3oC. The decrease in average temperature causes a decrease in energy consumption due to the use of air conditioners by 1.56-1.92%. Keywords: global warming, green facade, thermal evaluation, vertical greenery system

Abstract

To obtain ethanol purity >99.5%, an adsorption method using Lampung Natural Zeolite (ZAL) is needed. In order to be used as a zeolite adsorbent, activation must be carried out using UV light lamp irradiation germicidal lamp 254 nm, blacklight lamp 360 nm and insect lamp 546 nm. The results of the BET characteristic test showed that the surface area of ??the non-treated zeolite was 41,331 m2/g, the germicidal lamp was 41,158 m2/g, the black light lamp was 40,399 m2/g and the insect lamp was 38,796 m2/g. The largest total pore volume was obtained from UV germicidal lamp activated zeolite 0.0690 cc/gram and the average pore size was found in insect lamp activated zeolite 35.57. After the activation of the zeolite, pellets were formed using a binder from wheat flour with a composition of 35% by weight of zeolite, then the zeolite was calcined to remove the binder that was still attached and opened the pores that were closed by the binder. The results obtained were dehydrated ethanol to increase purity using zeolite activated by UV germicidal lamp 98.69% v/v for 45 minutes, blacklight and insect lamp 98.69% v/v for 55 minutes.

Abstract

Palm oil shells are solid waste from the palm oil processing industry. In 1 ton of palm oil produces 6.5% shell waste. Solid waste can be converted into fuel as a substitute for oil, namely bio-briquettes as an alternative fuel through a combustion process with less air. This study aims to determine the effect of time variations on the quality and yield of bio-briquettes produced using a combined pretreatment method of densification (with additional binder) and torrefaction at a temperature of 275 oC and time variations of 30, 45, 60, 75 and 90 minutes. Torrefaction is a new method in the briquetting process where this method takes place at low temperatures. The results showed that the longer the torrefaction time, in general, the value of water content, ash content, volatile matter content, fixed carbon value and burning time also increased. However, this is inversely proportional to the yield value of the resulting product, so the best quality is obtained in 75 minutes with a moisture content of 0.86%, ash content 2.38%, volatile matter content 18.23%, fixed carbon value 78.51 %, product yield is 36.3165% and calorific value is 5964 Kcal/kg.

Abstract

Proses gasifikasi terjadi di reaktor gasifikasi yang disebut gasifier. Di antara jenis proses gasifikasi, yang paling sederhana dan mampu menghasilkan gas dengan kualitas yang cukup baik adalah jenis gasifikasi downdraft. Dalam penelitian ini akan digunakan gasifier downdraft di mana udara pembakaran akan masuk dari bagian atas atau samping di zona pembakaran dan syngas akan keluar dari bagian bawah reaktor. Pada penelitian ini, gasifikasi biomassa berbahan baku kayu karet dengan tujuan untuk mengetahui pengaruh AFR dan suhu terhadap nilai kalor dan komposisi syngas dengan menggunakan downdraft gasifier dan batubara sebagai stabilisator. Hasil dari penelitian ini terdapat persentase penurunan CO, H2, dan CH4 karena AFR meningkat, pada 0,64 AFR kadar CO2 menurun secara signifikan pada suhu 700ºC - 800ºC yaitu sebesar 6,01% tanpa batubara. Kondisi optimum terbaik terdapat pada suhu 0,64 AFR dan suhu 800ºC, pada kondisi tersebut didapatkan kadar CO2 sebesar 18,77%. Kondisi operasi terbaik pada penelitian terjadi pada air fuel ratio (AFR) 0,64, temperatur 800ºC dengan batubara sebesar 33,95% dan tanpa batubara sebesar 31,54%.

Abstract

Solid waste has always been a problem for developing countries. In Bandar Lampung, the traditional market is the second largest contributor of solid waste, after households. Data for Traditional Market Solid Waste (TMSW) composition and generation rate in Bandar Lampung is rarely found, even though, data is needed to write the policy for TMSW management and its recycling potential. This research aims to provide data on TMSW composition, generation rate and chararacteristic in Bandar Lampung, also its recycling potential. The sample from 10 of 31 traditional markets in Bandar Lampung is collected for 8 consecutive days in morning and afternoon. Then, the sample was processed to obtain its composition, generation and density. 48.06% of TMSW compositions is donated by vegetable. Meanwhile, metal is rarely found in traditional markets, with only 0.37%. The average density of TMSW is 180.11 kg/m3, while Kangkung Market has the highest density with 237.84 kg/m3 and Cimeng Market has the lowest TMSW density with 123.07 kg/m3. The generation rate of TMSW is 53,602.35 kg/day. Biodegradable wastes from traditional markets in Bandar Lampung, with 53% water contents, can be potentially recycled by composting and/or anaerobic digester because of its economic value and characteristic. Keywords:   Recycling, Solid Waste Management, Traditional Market Solid Waste, Waste Characterization
