In 2015, the United Nations Environment Program (UNEP) revealed that there are 280 million tons of plastic produced globally each year This research was conducted to convert plastic waste to be useful products. Polyethylene Terephthalate (PET) is converted into gas and coke using thermal cracking method and a stainless steel batch type reactor. Looking for the effect of temperature variations on the thermal cracking of PET plastic waste and studying the kinetic phenomena are the purpose of this research. A total of 40.17 grams of Polyethylene Terephthalate (PET) plastic waste was cracked in a batch reactor at 450, 500 and 550 °C for 15, 30 and 45 minutes. The highest percent yield of gas (89.92%) was resulted at 30 minutes of reaction time and 550 °C of the reaction temperature. The highest percent yield of coke (26.01%) was resulted at 45 minutes of reaction time and 500 °C of the reaction temperature. The activation energy for the highest percent yield of coke, 26.01% is -9,257701 kJ/mol, otherwise the process needs to be revised to get the positive activation energy.

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

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

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
