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
Serangga hama walang sangit merupakan salah satu faktor kegagalan dalam budidaya tanaman padi. Untuk mencegah peningkatan serangan pada tanaman padi, dibutuhkan instektisida alami yang mampu meningkatkan mortalitas walang sangit. Tujuan penelitian ini adalah meningkatkan mortalitas serangga hama walang sangit melalui pemberian agen hayati larutan Beuveria bassiana pada berbagai taraf konsentrasi. Larutan Beuveria bassiana disempotkan pada walang sangit di dalam sungkup jaring pada rumpun tanaman padi. Dosis yang diberikan antara ekstrak beuveria bassiana dengan air menggunakan perbandingan 2 ml/L, 5 ml/L, 8 ml/L, dan 10 ml/L. Hasil penelitian menunjukkan dosis terbaik untuk pengendalian hama walang sangit pada tanaman padi adalah 10 ml larutan beuveria bassiana per liter air. Hal ini ditunjukkan dari mortalitas walang sangit tertinggi yaitu 76,92 % selama 12 hari pengamatan. Pada dosis 10ml/L telah menunjukkan perubahan fisik pada serangga hama yang telah mati. Cendawan beuveria bassiana muncul di seluruh jaringan tubuh walang sangit yang telah mati. Pertumbuhan cendawan mulai tampak menyelimuti serangga hama yaitu hari ke 8 menggunakan dosis 8 ml/L air dan 10 ml/L air. Di samping itu, dosis yang menunjukkan mortalitas terendah pada walang sangit adalah 2 ml larutan beuveria bassiana per liter air. Mortalitas walang sangit pada dosis ini adalah 28,57 % selama 12 hari pengamatan. Kata Kunci: agen hayati, larutan beuveria bassiana, pengendalian hama, serangga hama walang sangit, tanaman padi
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.

Untuk mempermudah pemanfaatan limbah batang singkong, diperlukan mesin yang dapat merubah ukuran batang singkong menjadi lebih kecil. Perajang Batang Singkong (Rabakong) tipe TEP 2 merupakan mesin yang dapat menghasilkan rajangan batang singkong berbentuk serbuk halus. Tujuan pnelitian ini adalah untuk mendapatkan analisis kelayakan mesin Rabakong tipe TEP 2 yang dapat digunakan sebagai pertimbangan pemanfaatan bagi masyarakat luas. Penelitian ini dilakukan dengan menganalisis data mulai dari biaya pembuatan mesin sampai biaya pengujian atau biaya operasi mesin Rabakong tipe TEP 2. Analisis yang dilakukan meliputi analisis biaya mesin, analisis BEP, dan analisis kelayakan. Berdasarkan hasil analisis ekonomi mesin Rabakong tipe TEP 2 menghasilkan pendapatan sebesar Rp. 26.258.447,45 dengan jumlah jam kerja 8 jam/hari. Sehingga mesin ini layak untuk digunakan dengan tujuan ekonomi tertentu. To facilitate the utilization of cassava stem waste, a machine is needed that can reduce the size of the cassava stems to be smaller. Cassava stem chopper (Rabakong) type TEP 2 is a machine that can produce chopped cassava stems in the form of fine powder. The aim of this research is to obtain a feasibility analysis for the Rabakong type TEP 2 machine which can be used as a consideration for the utilization to the public. This research was conducted by analyzing data ranging from machine manufacturing costs to testing costs or operating costs for the TEP 2 Rabakong machine. The analysis carried out includes machine cost analysis, BEP analysis, and feasibility analysis. Based on the results of the economic analysis of the Rabakong type TEP 2 engine, it generates an income of Rp. 26,258,447.45 with the number of working hours 8 hours/day. So that this machine is suitable for use for certain economic purposes.
Preparation of cassava seeds using a machete or hand saw takes a long time, the results are not uniform, and there is a potential for damage to cassava seedlings. The double block cutter type cassava stem cutting machine has been designed to produce high capacity and good quality cassava seeds. This study aims to test the performance of the cassava stem cutting machine with the double block cutter type. Performance tests include measuring machine working capacity, fuel consumption, seed uniformity, and planting test. The cutting test was carried out using 3 varieties of cassava seedlings. The machine works at a rotational speed of 3800 rpm and the test was carried out with various feeding loads, namely 3 rods, 4 rods, and 5 rods with. Each test was repeated 3 times. Cassava stem cutting machine (Petokong) is suitable for producing cassava stems with an average working capacity of 16275 seeds/hour. The results of the Anova test showed that the number of baits and varieties of cassava seeds and their interaction had a significant effect on the working capacity of the Petokong machine. Variations in fuel consumption are thought to be influenced by the variety of cassava stem used, which is influenced by the stem diameter of each variety. The Petokong machine is far superior to manual cutting using a machete or saw which can only produce 815 and 3005 seeds/hour per hour. The average fuel consumption is 1.82 liters per hour. Seed uniformity is about 98% and seedling damage can be minimized to 2%. The seeds produced by the Petokong machine can grow well, which is indicated by the appearance of shoots and an even distribution of roots.
