Abstract

Uncontrolled population growth and urban displacement will continue to be the causes of the rise in garbage. Waste that accumulates for too long and becomes dense and scattered will cause pollution, i.e., the spread of pests and unwanted odors. The Abdimas team sees the role of compost houses as an optimal solution to provide knowledge or education while growing public interest and awareness of the importance of garbage control and reusing it to increase the economic value of partners and communities. The purpose of this activity is for the community to be able to have a positive impact on the establishment of other composite houses around it. The activities were conducted in the form of training and supporting workshops at the PCU Composite House, and follow-up of the implementation results was conducted through the visit of the Abdimas team at the location of the partner as a post-execution evaluation of the activities. Implementation of this activity is divided into three stages, namely: preparation of training, implementation of the training, and non-continued application of training results at the partner site. The training event is packed with the topic "Organic Composite Making Skills Upgrading Training". Based on the observations of the visits carried out by the Abdimas team, one of the partners is currently working on the construction of a new composite house, while the other partner site has already implemented fertilizer production activity for the fulfillment of the element of charity for the partners' crops. The construction of compost houses and garbage banks has proven to help in controlling household trash while providing economic value for partners.

Abstract

Sampah tidak selalu memberikan dampak buruk kepada masyarakat. Warga Kampung Herbal Nginden Jangkungan melihat peluang usaha dari sampah untuk mengingkatkan kesejahteraan warganya dengan mengelola sampah organic melalui prinsip sirkular ekonomi. Sampah organik diolah menjadi pupuk kompos membutuhkan tenaga kerja untuk memilah, merajang sampah, dan mengolah hasil rajangan. Setelah menyerahkan mesin perajang dan melakukan pelatihan pada Desember 2023, pengelola rumah kompos Kampung Herbal telah memanfaatkan mesin perajang sampah dengan memperkerjakan tiga orang warga yang tidak memiliki pekerjaan pasca Covid-19. Melalui diskusi yang dilakukan, pelatihan yang telah diberikan ke pihak pengelola telah ditransferkan ilmunya kepada warga Kampung Herbal sehingga tiga warga yang tidak memiliki pekerjaan dapat bekerja kembali untuk menghidupi keluarganya. Tiga orang pekerja yang melakukan pengolahan sampah menjadi pupuk kompos, Hasil olahan sampah organik yang diubah menjadi pupuk juga telah digunakan warga Kampung Herbal untuk menyuburkan tanaman herbal hingga menghasilkan produk sereh dapat dijual ke beberapa hotel untuk meningkatkan nilai ekonomisnya.

Abstract

Efforts to improve the performance of motorcycle brake system performance are essential for enhancing riding safety, particularly at high speeds. The main objective of this study is to evaluate the effect of a brake duct on brake disc cooling using computational fluid dynamics (CFD). This study also aims to determine the optimal brake duct design for motorcycles applications. To assess the accuracy of the numerical simulations, wind tunnel experiments were conducted to quantify the error between the simulation and experimental results. The validation results showed that the simulation error was 5.64%, indicating good agreement with the experimental data. The simulation was performed by modelling the motorcycle braking system and brake duct, then analyzed using ANSYS Fluent. To identify the optimal brake duct configuration, variations in the inner radius R, duct length L, and diffuser size D were evaluated. The best configuration was defined as the design that produced the lowest pressure loss and the highest ΔP statis. The simulation results indicate that the optimal configuration corresponds to R = 20 mm, L = 180 mm, and D = 8.75mmx 10mm.
