PELATIHAN PENGOLAHAN SAMPAH DAN BISNIS DROPSHIP DI KELURAHAN TANJUNGMEKAR - KARAWANG
Kelurahan Tanjungmekar merupakan salah satu kelurahan dari 8 (delapan) kelurahan yang ada di Kecamatan Karawang Barat. Sebuah wilayah yang merupakan bagian dari kawasan industri, sehingga banyak para kepala keluarga dan pemuda mengais rezeki pada perusahaan-perusahaan yang ada. Di sisi lain aktivitas ibu-ibu rumah tangga dalam kesehariannya, terlihat hanya sekedar berbincang dan merumpi tanpa ada aktivitas yang produktif. Kelurahan Tanjungmekar juga merupakan wilayah yang dibatasi oleh Sungai Citarum, sehingga membuat Tanjungmekar tidak bisa terhindar dari luapan air Sungai Citarum, dan menyebabkan banjir. Terkait dengan hal tersebut, sangat disayangkan bahwa masih banyak warga masyarakat yang belum peduli lingkungan, mereka masih membuang sampah sembarangan. Berdasarkan hal tersebut, Tim Abdimas Universitas Bhayangkara Jakarta Raya berinisiatif untuk melakukan kegiatan Pelatihan Pengolahan Sampah dan Pelatihan Bisnis Sistem Dropship pada Warga
Masyarakat RW. 02 dan RW. 03 Kelurahan Tanjungmekar Kecamatan Karawang Barat Kabupaten Karawang. Tujuan dari kegiatan dimaksud adalah untuk memberikan keterampilan pengolahan sampah dan keterampilan berbisnis dengan sitem dropship khususnya bagi ibu-ibu pemberdayaan kesejahteraan
keluarga (PKK). Luaran yang diharapkan pada kegiatan Abdimas ini adalah, ibu-ibu PKK dapat mengolah sampah, selanjutnya sampah bisa menjadi produk yang bermutu, dan dapat meningkatkan perekonomian keluarga dengan berbisnis sistem dropship
Effect of Low Flow Rate of Air Injection on Remazol Red Degradation in Contact Glow Discharge Electrolysis Reactor
Background and Objective: The plasma electrolysis requires a high amount of energy at the beginning of the process. The purpose of the study was to examine how air injection could reduce the energy of plasma formation. Furthermore, the effect of the flow rate of injected air on hydroxyl radical production and Remazol Red degradation were also studied. Methodology: In this research, the air was injected directly through the glass sheath at the anode in Contact Glow Discharge Electrolysis reactor. Result: For the same energy input, the higher the flow rate of air injection, the radical hydroxyl concentration increased to an optimum point at a certain flow rate. Moreover, the rate of airflow at optimum condition increased with increasing voltage. An airflow rate of 0.05 L/min and a voltage of 600 Volts was the optimum condition. The concentration of hydroxyl radical at this condition produced 19.0849 mmol/L after 30 minutes. Conclusion: This was an increase of 48.43% in comparison with the amount of •OH where air injection was not used. The presence of air injection also increased the degradation of Remazol Red. Within 5 minutes, Remazol Red degradation had reached 86.37% at an airflow rate of 0.05 L/min. This indicated a 53.59% increase compared to the degradation process without air injection
Air Injection Effect on Energy Consumption and Production of Hydroxyl Radicals at Plasma Anode
Background and Objective: Plasma anode has been known as a very productive method of producing hydroxyl radicals that oxidize effectively in almost all organic and non-organic liquids. This research was conducted to investigate the effect of air injection and anode depth variation on required energy for plasma generation and production of hydroxyl radicals. Material and Method: A batch reactor (diameter 130 mm, height 190 mm) with tungsten electrodes (cathode diameter 6 mm and anode diameter 0.5 mm) was used by applying a continuous cooling system. The experimental parameters were composed of different rate of air injection (0, 2, 4, and 6 Lmin-1) and various depth of anode (5, 25, 45, and 65 mm). Current was observed at various voltage (20 – 700 V) in 30 second for each voltage. Result: The energy consumption of plasma formation was getting smaller at higher rate of air injection, while at deeper anode position, the energy consumption found higher. Although the •OH production became lower at a higher rate of air injection, the process efficiency observed higher. Conclusion: This research clarified that air injection on plasma anode and the anode depth position affected the energy consumption and production of hydroxyl radicals where the addition of air injection and variation of the anode depth could reduce energy consumption and also improved process efficiency
