Abstract

Pupuk Organik Cair (POC) merupakan salah satu inovasi dalam bidang pertanian yang bertujuan untuk meningkatkan produktivitas tanaman dengan pendekatan yang lebih ramah lingkungan. Penggunaan pupuk kimia secara berkelanjutan dapat menurunkan kesuburan tanah, merusak struktur tanah, dan meninggalkan residu kimiawi pada tanaman yang berisiko membahayakan kesehatan manusia, khususnya dalam jangka panjang. Metode yang digunakan adalah pendekatan deskriptif kualitatif dengan pengumpulan data primer dan sekunder, serta metode persuasif melalui sosialisasi pemanfaatan sampah organik sebagai bahan baku pembuatan EM4. Pembuatan pupuk organik cair EM4 yang berbasis bahan organik diharapkan dapat menjadi alternatif yang lebih ramah lingkungan, ekonomis, dan berkelanjutan. Tujuan dari pengabdian ini adalah untuk menghasilkan pupuk organik yang aman, murah, serta mendukung keberlanjutan. Hasil yang diperoleh menunjukkan bahwa penggunaan pupuk cair EM4 secara signifikan dapat meningkatkan pertumbuhan tanaman. Penggunaan pupuk organik cair juga terbukti meningkatkan daya serat nutrisi oleh tanaman dan mengurangi pencemaran lingkungan dibandingkan dengan pupuk kimia. kesimpulan yang diperoleh adalah pupuk organik cair memiliki potensi besar sebagai alternatif yang efektif dan berkelanjutan dalam praktik pertanian modern, yang dapat mendukung produksi tanaman secara optimal dengan dampak lingkungan yang minimal

Abstract

Leveraging maritime transport for bulk material shipments is a common approach in supply chain cost optimization efforts. However, the operational aspects of this shipping method are characterized by limited visibility and high levels of uncertainty. This condition is negatively correlated with the company's ability to meet established service level standards, ultimately leading to a decline in consumer trust. This research develops a simulation model to evaluate three scenarios aimed at improving service level. The three factors evaluated are optimization of port operating hours, implementation of a reorder point system, and increasing ship capacity. By implementing a combination of these strategies, the existing distribution system can be significantly improved. The results of this study indicate that implementing a combination of these scenarios can substantially improve the performance of the existing system. The most influential factor is the implementation of a reorder point (Factor 2), which results in an increase of 13.80%. The factor combination that yields the highest service level is scenario number 10, which achieves a service level of 92.36%.

Abstract

This research has an urgency to develop environmentally friendly materials as an alternative to synthetic fiber-based composite materials that are widely used in the automotive, construction, and manufacturing industries. This research develops bamboo fiber-based composites that have advantages such as corrosion resistance, lightweight, inexpensive, and competitive in strength with metal materials. The goal of this development is to produce a lightweight, strong, and elastic material, which can be applied to a variety of products. The composite sample was made using an epoxy resin matrix using the hand lay-up method. Three variations of fiber volume fractions (10%, 20%, and 30%) were used to explore their effect on load distribution and energy absorption ability during impact. The results showed the highest value of 0.552 J/mm2 at Sp30.6, which was a fiber volume fraction of 30%, while the lowest value at Sp10.4 was a 30% volume fraction of 0.0251J/mm2. This shows that the increase in the volume fraction of petung bamboo fibers in the epoxy matrix significantly increases the impact toughness of the composite. This research is expected to determine the optimal composition to produce the best impact strength, so it is expected to produce an ideal material configuration for sustainable industrial applications.

Abstract

Suspension is the most important thing that must be taken into account because it greatly affects driving comfort on the road. The working mechanism of the suspension consisting of spiral springs and shock absorbers is loaded vertically from the weight of the body, driver, and passengers. The uneven shape of the road surface in the form of potholes or bumps will greatly affect the comfort of the driver. This study aims to determine the effect of suspension work and the optimal value of vibration that occurs on one of the wheels of the vehicle against vertical dynamic loads. The method used in this study uses the Taguchi method which is used to determine the optimum dynamic load conditions against vibration in the suspension system.   The characteristics used in this method are "Smaller is better". Several variables such as bump height, tire pressure on the wheels, as well as vehicle body weight and passenger weight are necessary factors to calculate optimal dynamic load conditions against vibration in the suspension. Based on the results of the optimum value conditions obtained, namely the height of the mound of 5 cm, tire pressure of 32 Psi, load of 84 kg, and dynamic load of 71 kg. From the results of the contribution rate to the ANOVA obtained, factor A (bump height) and factor D (dynamic load) are significant factors while factor B (tire pressure) and factor C (load load) are insignificant factors. Under optimal conditions, there was a decrease in suspension vibration value by 49.65%.
