Abstract

The provision of fiber optic infrastructure in dense urban areas like Taman Kambang Iwak, Palembang, often faces constraints related to excavation permits and potential damage to city aesthetics. 5G-based Fixed Wireless Access (FWA) technology serves as a strategic alternative solution to deliver high-speed broadband access without requiring physical cable installation to the user's premises. This study aims to design a 5G FWA network utilizing the 3500 MHz frequency (Band n78) with a 100 MHz bandwidth. The design was conducted through simulation using RadioPlanner 3.0 software with the Okumura-Hatta propagation model tailored for urban environmental characteristics. Analyzed parameters included signal coverage based on Reference Signal Received Power (RSRP), Reference Signal Received Quality (RSRQ) and data capacity (throughput). Simulation results indicate that the design scenario using three sectoral antennas is capable of providing "Good" category signal coverage in the target area. In terms of data performance, the system achieves a maximum downlink throughput of up to 750 Mbps and uplink ranging from 500 Mbps to 750 Mbps. (Discussion) Based on these results, the implementation of 5G FWA at the 3.5 GHz frequency is proven feasible and meets the standards for high-speed data service requirements in the Taman Kambang Iwak area..

Abstract

Penelitian ini bertujuan untuk menganalisis potensi penggunaan pendinginan evaporatif sebagai metode penyimpanan ikan alternatif bagi pedagang di Pasar Panorama, Kota Bengkulu. Latar belakang penelitian ini didasarkan pada permasalahan penyimpanan ikan di pasar tradisional yang mengandalkan es batu, sementara kondisi lingkungan yang panas dan lembap mempercepat pencairan es dan menurunkan kualitas ikan. Penelitian ini menggunakan metode deskriptif kualitatif melalui observasi lapangan langsung dan studi literatur terkait konsep termodinamika dan penerapan pendinginan evaporatif pada bahan pangan. Hasil observasi menunjukkan bahwa es batu mencair dengan cepat akibat suhu pasar yang tinggi dan sirkulasi udara yang minim. Studi literatur menunjukkan bahwa pendinginan evaporatif dapat menurunkan suhu lingkungan melalui proses penguapan air dan menciptakan kondisi penyimpanan yang lebih dingin dan stabil. Meskipun tidak dapat mencapai suhu dingin yang ideal untuk ikan, pendinginan evaporatif berpotensi sebagai sistem yang memperlambat pencairan es, menghambat kenaikan suhu, dan membantu menjaga kesegaran ikan lebih lama. Kesimpulan penelitian menunjukkan bahwa pendinginan evaporatif layak dipertimbangkan sebagai teknologi tepat guna yang mendukung penyimpanan ikan di pasar tradisional, mengurangi penggunaan es batu, dan mengurangi biaya operasional pedagang.
Valuation and Action Recommendations on the Control Panel of PT Bukaka Teknik Utama Duri's Pumping Unit Using Failure Mode and Effect Analysis (FMEA) : Valuasi dan Rekomendasi Tindakan Pada Panel Kontrol Pumping Unit PT Bukaka Teknik Utama Site Duri Menggunakan Failure Mode and Effect Analysis(FMEA) Son, Putut; Miratul Ansyari, Alif; Susianti, Elva

Abstract

PT Bukaka Teknik Utama Site Duri is a company engaged in the oil and gas equipment sector and collaborates with PT Chevron Pacific Indonesia in managing sucker rod pump type pumping units for crude oil extraction processes. The pumping units are powered by 75 HP electric motors that are controlled and monitored through a control panel. The control panel plays an important role in maintaining operational reliability and safety as it is equipped with various protection components, such as overload, over voltage, over current, and thermal protection. However, based on operational data, there are still control panel malfunctions that cause pump operations to stop and daily oil production targets to not be achieved, as well as increasing the risk of damage to the drive motor. This study aims to conduct a risk assessment and provide recommendations for improvements to the pumping unit control panel using the Failure Mode and Effect Analysis (FMEA) method. The FMEA analysis results show that the contactor and overvoltage components have the highest risk levels, while the fuse and MCB have the lowest risk levels. The recommended actions include replacing components with higher specifications and implementing preventive measures such as repairing the grounding system and adding protection against moisture and dust. The implementation of these recommendations is expected to reduce the failure rate and improve the reliability of the control panel in the next operational period.

Abstract

BPS data from 2021 states that coconut production in Indonesia is the largest in the world, with a total production of 988.3 thousand tonnes of coconuts. The largest coconut production comes from Riau Province, with a production of 1,100 tonnes. Generally, coconuts are used to make coconut milk, leaving behind coconut pulp as waste. This waste is considered garbage because it no longer has any beneficial value, so it is disposed of directly. This disposal has an impact on the environment because biomass waste that is disposed of directly will cause a foul odour and methane gas emissions that are 20 times more harmful than CO2 emissions, even though coconut husk waste contains nutrients that can be processed into a new energy source in the form of biogas. This research aims to analyse the biogas potential that can be generated from coconut husk waste, including the potential for electricity generation and its economic analysis. This research uses the anaerobic respiration method to produce biogas in an anaerobic digestion reactor simulated using the SuperPro Designer application. From the research conducted, it was found that the potential biogas that can be produced from coconut husk waste in a year in Riau Province is 15,321,231.9 m3, which is obtained from 134 tonnes of coconut husk waste in Riau Province in 2021. In addition, the biogas produced is capable of generating 141,703,473 kWh of electricity per year, with a potential revenue of Rp. 212,555,209,500 and an annual profit of Rp. 163,532,903,700. With a B/C ratio of 1.26 and a payback period of 9.6 months, it can be said that this investment is profitable and feasible to be realised.   Keyword: Biogas, Coconut Waste, Electricity, Economics.
