Abstract

Energy auditing is a method of increasing energy efficiency. An energy audit is conducted to provide an overview of energy use, analyze the electrical system, and determine potential cost savings. The laboratory of the national food and drug agency (BPOM) in Manokwari has problems with electricity that often cause interruptions, power outages, and expensive bills. Therefore, this research was conducted to audit the energy used in the laboratory of the BPOM of Manokwari, with a building area of 1,484 m2 and an installed power of 105 kVA. In this laboratory building, a diesel generator with capacity of 5 kVA is installed as a backup energy source and the generator has its own installation line. According to the calculation results before auditing, the energy consumption intensity (IKE) value obtained per month is 10.18 kWh. Energy audit through lighting loads and air conditioning systems. Then the recommendation through energy savings for lights and air conditioners is 274.12 kWh/month and 639.32 kWh/month, respectively. Therefore, total savings are 913.44 kWh/month, or about IDR 1,541,886.72/month.

Abstract

Pada penelitian ini, telah dilakukan pengujian tahap awal sifat tahan api batu bata yang dibuat dari tanah merah dan alumina (Al2O3) sebagai bahan paduannya. Bahan Al2O3 diperoleh dari ekstraksi limbah bungkusan susu formula, sedangkan tanah merah yang digunakan berasal dari daerah distrik Warmare, Manokwari Barat, Papua Barat. Analisis kandungan tanah merah menggunakan XRF diperoleh komponen utama berturut-turut 39.57%, SiO2, 30,94% Al2O3 dan 23,73% Fe2O3. Proses ekstraksi dilakukan dengan metode gravimetri, melarutkan limbah alumunium dalam larutan HCl 18%, selanjutnya pengendapan Al(OH)3 menggunakan larutan Amoniak 25%. Konversi endapan Al(OH)3 menjadi Al2O3 dengan proses kalsinasi pada suhu 800 °C, hasil analisis XRF terhadap ekstrak yang diperoleh menunjukan 89.1% Al2O3, 3.95% SiO2, 3.06% NA2O dan 1.79% MgO. Batu bata dengan kandungan Al2O3 30% dan 50% menunjukan sifat tahan api setelah dibakar pada suhu 300 °C dan 500 °C karena batu bata tersebut tidak mengalami keretakan.

Abstract

Community Service Program (CSP) is a form of manifestation of community service that is in line with the demands and realization of the Tridharma of Higher Education. It is hoped that through CSP, students will be able to utilize knowledge, analyze community conditions, and provide solutions to various problems (social, economic, health, and education) in villages especially. The CSP implementation method consists of 4 stages, namely the initial stage (literature study, location survey, and interviews), the planning stage, the implementation stage, and the monitoring and evaluation stage. The CSP activity which took place in Mandopi Rimom Village, Manokwari Regency was carried out for 36 days (24 June - 8 August 2022) involving 1 field supervisor and 9 students from different study programs. A total of 35 work/activity programs (wp) have been successfully implemented involving participation and cooperation from village residents, school officials, posyandu officers, district health services, and the LPPM of Papua University. The work programs cover 8 areas of activity, namely village administration (7 wp), education (5 wp), health (5 wp), environment (10 wp), religion (2 wp), agriculture (2 wp), animal husbandry (2 wp) and socio-cultural economics (2 wp). The KKN seminar was held on the 35th day to present the results of the activities as well as get appreciation and suggestions as recommendations for implementing KKN in the next period. The results of the work program, activity documentation, obstacles, and suggestions/recommendations are then prepared in the form of a report to be submitted to the university's LLPM.

Abstract

The aim of this research is to determine the potential of biodiesel from the algae Sargassum binderi from the North Coast of Manokwari by determining the lipid components contained in the algae. Lipid extraction was carried out using the soxhletation method with n-hexane solvent. Lipid percentage was determined via GCMS analysis. The research results obtained 4 lipid components consisting of hexadecanoic acid (palmitic acid), 9,12-hexadecadienoic acid, 9-octadecenoic acid (Z) (oleic acid) and octadecanoic acid (stearic acid) with a percentage of 18.12%, 4.75%, 19.4% and 4.29% respectively. The total percentage of lipid components extracted was 46.56%, almost half of the total extract.

Abstract

The red fruit (Pandanus conoideus) is an endemic plant from Papua, known for its distinctive color and shape. This fruit is recognized for its bioactive properties, such as antioxidant, anti-inflammatory, and antihyperglycemic effects. Its high pigment content is believed to have potential as a sensitizer in DSSC applications. However, research on this topic remains underexplored. Therefore, the aim of this preliminary study is to investigate the potential of red fruit pigments for DSSC. The characterization of red fruit pigments was conducted through phytochemical screening, FTIR and UV-Vis spectral analysis, as well as literature reviews. Pigment extraction was carried out using maceration without involving drying or grinding processes. Phytochemical screening results revealed that the macerate contains flavonoids, alkaloids, phenolics and terpenoids, compounds commonly used as natural pigments in DSSCs. FTIR analysis showed the presence of functional groups such as carboxyl (-COOH), carbonyl (C=O), and hydroxyl (-OH), which can act as effective anchoring groups when interacting with nanosemiconductor surfaces. Meanwhile, UV-Vis analysis showed absorption peaks in the UV region (wavelength 204–399 nm) and the visible region (wavelength 400–550 nm). Based on literature studies and research findings, it can be concluded that the pigments in red fruit have potential applications as DSSC sensitizers.

Abstract

The demand for electrical energy needs is always projected to increase by 2,214 (TWh) in 2050 or an increase of 9 times compared to the previous years of 254.6 TWh, it's just that current energy needs are still dominated by non-renewable energy which has limitations and does not require energy. environmentally friendly. Therefore, renewable and environmentally friendly energy sources are needed. Utilization of solar energy which is converted into electrical energy is a solution to reduce the use of non-renewable energy. The average daily solar radiation in Indonesia is 4.8 kWh/m². The purpose of this research is to design PLTS Rooftop at the Rectorate Building of the Papua University using helioscope software and to analyze the estimation of electrical energy savings. In designing, using 198 Tallmax TSM-PD14 320 Wp solar modules, SMA Sunny Tripower 20000TL-US brand inverter with a capacity of 4 units (20kW) and an AC Combiner Box containing protective equipment. The simulation results show that the highest electricity production was in May at 8,031.50 kWh and the lowest was in February at 5,997.60 kWh. So from the calculation, the estimated average electrical energy savings is 18%

Abstract

The quality of electricity includes several things, including continuity of distribution, length of blackout time, voltage stability. One of the causes of declining electricity quality is the shrinkage that occurs in the electric power network, network losses cannot be avoided but can be minimized by shortening the network, performing maintenance and maneuvering the load. Energy losses in the electrical system come from the power generation, transmission and distribution system. In the transmission system, energy losses can be minimized by increasing the transmission voltage to high and extra high voltage levels. The load curve is a curve in a time range which shows the value of electrical energy use and load for a feeder so that PT. PLN (Persero) UP3 Manokwari can estimate power requirements. Expense curves can be divided into three types, namely daily curves, monthly curves and annual curves. Research throughout October 2021 used quantitative methods in processing data and calculating losses so that the power loss was 2.0070% and the energy loss was 1.9847%. This loss is still far below the state electricity company standard D3.002-2 (2008) in range of 5% to 10%.
