Abstract

A series of analyses techniques were performed to study the influence of different acid concentrations on the rock properties during the acidizing process. Based on the Thin section and Routine Core Analysis (RCA), the calcite content have effect on the reservoir quality from the aspect of rock-fluid properties. In this paper, the physical and mineralogical responses to rock acidizing of carbonate rock are evaluated. This study found that calcite content decreases approximately 25% from the total calcite content of rock samples after the addition of HCl. Scanning Electron Microscope (SEM) Analysis show that samples treated using HCl 15% provide a wider pore size distribution, resulting in the increasing permeability fluid flow rate

Abstract

Photoanode is a component of the dye-sensitized solar cell (DSSCc) which is synthesized from metal oxide semiconductor material with nanoparticle size deposited on transparent conductive glass. TiO2 powder was synthesized by mixing 20 mL of Titanium (III) chloride (TiCl3) with 100 mL of the equator and stirred for 1 hour. TiO2-SnO2 thin films have been successfully synthesized using the coprecipitation method and coated on ITO (Indium Tin Oxide) substrate by doctor-blade technique. The structure and morphology of the films were investigated by XRD and SEM respectively. The analysis of optical characteristics shows that the absorbance of TiO2 photoanode is in the wavelength range of 300-600 nm while SnO2 is in the wavelength range of 300-870 nm. The results showed that the synthesized film with SnO2 had a stronger anatase formation than the film with pure TiO2. Finally, incorporating SnO2 into the TiO2 matrix is an effective strategy to improve the overall properties of solar cells in future applications

Abstract

Inventory control is one of the problems faced by Universitas Pertamina. In the management of inventory, especially Consumable items, Universitas Pertamina does not determine the limited value of inventory that must be stored. Thus, this causes asset management difficult to determine the ordering quantity for each item and how many items should be stored in the warehouse. The purpose of this study is to recommend policies related to the value of safety stock, minimum stock, and maximum stock for each consumable item. The method used is the Min-Max Stock method. In addition, the ABC classification method is also used to classify items based on the level of usage. The results of this study are in the form of value limits for safety stock, minimum stock, and maximum stock. Then the priority item classification must be managed. Based on the calculation results, it is found that by using the min-max method, Universitas Pertamina can save up to 30% of inventory costs compared to the current policy.

Abstract

Warehouse costs contribute about 22% of the company's total logistics costs. Thus, a warehouse manager must have comprehensive knowledge of costs and cost triggers in the warehouse to be able to minimize costs while keeping customer satisfaction. One effective way to minimize warehouse costs is by conducting the cost analysis. Although PT XYZ is one of the biggest Fast Moving Consumer Goods (FMCG) companies in Indonesia applying one of the most comprehensive Enterprise Resource Planning software, its existing warehouse management support system occupies only standard Microsoft Excel. One of its warehouses, located in West Java, is responsible for more than 147,000 pallets each day, and the warehouse manager still uses Microsoft Excel with limitations in displaying the required information, especially the information related to the Cost Per Case (CPC) in every activity. Therefore, a template or dashboard that can provide information related to CPC in the warehouse is urgently needed. Given the importance of cost monitoring in the warehouse of PT XYZ, this research aims to create a dashboard that can make it easier for companies to monitor warehouse performance from a CPC perspective. The methods used in data collection consist of several processes, namely interviews, observations, and literature studies. While analyzing the needs of dashboard creation, this research uses the PureShare method. Thus, the results are obtained in the form of a proposed warehouse dashboard that can be used by the company to conduct cost analysis by providing information related to CPC of every activity in the warehouse, where the information presented on the dashboard is in accordance with the company's needs.

Abstract

Indonesia is a large archipelago with a tropical climate consisting of dry and wet seasons. Indonesia has had high rainfall and temperature over the year because this country lies on the equator lines. Moreover, severe global warming occurs because of the depletion of the ozone which affects the inclement weather, air, and temperature over the years. Therefore, special equipment is required to obtain appropriate thermal conditions by controlling the temperature. This paper proposed the PI controller to maintain the temperature in their nominal values and its temperature stability is analyzed using pole placement. In this study, the system model is 1st order, called first order plus dead time (FOPDT). Pole placement is utilized to improve the output signal to obtain the gain of the PI controller. The gain of the PI controller obtained is Kp as 0.36095 and Ki as I as of 0.00072231. The percentages of overshoot and steady-state error are 29.98% and 1.5% for the Ziegler Nichols method while 1.28% and 0.26% for the PI Tunner, respectively. PI controller is robust for this system where the pole's position is on the left side of the real axis and has small values of overshoot and steady-state error.

Abstract

Solar energy is one of the largest energy potentials that Indonesia has, which can be utilized in solar heater that are integrated with latent heat energy storage (LHTES). This research aims to investigate the effects of the operating conditions of flow rate and inlet temperature on the performance of the annulus type Low-Temperature LHTES using Computational fluid dynamics method in which the enthalpy-porosity is used as the solidification model. The results indicate that the increase of performance can be obtained by increasing the flow rate and inlet temperature. The increase in flow rate will promote higher heat transfer thus produce better performance up to 11.91% and 24.91% during charging and discharging, respectively. Meanwhile, increasing the inlet temperature will increase the performance up to 192.72% during charging and 13.07% during discharging of the Low-Temperature LHTES system.

Abstract

Membrane technology is an emerging alternative in water treatment. This study aims to synthesize a filtration membrane made of polysulfone polymer with the addition of ZnO in order to enhanced the membrane antibacterial/antibiofouling property. The membrane was manufactured via Non-Induced Phase Separation (NIPS) phase inversion of the polymer casting solution. The composition of ZnO was varied into 0%, 0.5%, 1%, 2%, and 3%. The results of the membrane synthesis were characterized using Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM), pure water permeability test, and selectivity test with a turbid meter. The hydrophilic properties of the membrane were analysed by measuring the contact angle, and the antibacterial characteristics were analyzed by the disc diffusion test. Analysis by FTIR showed the presence of a sulfone functional group (S=O) derived from polysulfone polymer and a methyl functional group (C-H) derived from PEG. SEM analysis showed that each variation of the polysulfone membrane had an upper surface structure that was close to the honeycomb structure. The pure air permeability test shows that the membrane is porous and able to pass through pure air. Selectivity test with a turbid meter showed that the membrane is selective to the feed stream that passes through it. Analysis of contact angle measurements showed that the polysulfone membrane surface was hydrophilic. Antibacterial activity analysis showed that polysulfone membrane had antibacterial ability with the largest zone of inhibition with a value 1.8 mm on the membrane with the largest concentration of ZnO.

Abstract

Today, electricity is one of the important components to drive the industrial process and other daily human activities. While the continuity of power supply through the power system grid is impressionable from disturbances such as a short circuit. In addition, the rapid development of distributed generation (DG) technology triggers the industry to use DG technology to maintain power quality and support for industrial processes. This paper proposed the coordination of over current relay (OCR) considering distributed generation (DG) to provide an extraordinary protection system in an electrical system network. The relay is coordinated with the other relay equipment to enhance the system more reliable, secure, and stable. To examine the efficacy of the proposed approach, the radial distribution system model is utilized in this paper where the DG is installed in bus 6. To compute the protection coordination index (PCI) and coordination time interval (CTI), the DG capacity is varied from 100 KVA to 1000kVA. From the simulation result, it could be seen that the installed DG that allowed in bus 6 was 900kVA because the CTI value reached convergence value as of 0.294 second for higher DC capacity than 900kVA. Moreover, the higher of DG capacity was injected to electrical system, the higher of PCI values was obtained.

Abstract

This research is about conducting a risk assessment of the pressure relief device unit by conducting a risk-based inspection analysis method. With the aim of mapping the risk categories in the PRD unit and providing recommendations for actions that must be taken to mitigate these risks with a quantitative approach. Pressure relief device (PRD) is a device that automatically discharges a certain pressure which is controlled by upstream static pressure coming from the valve and opens naturally with an increase in pressure above the opening pressure. The risk-based inspection method is carried out to calculate the risk value on an equipment by conducting analysis and calculations to determine the probability and consequence values on the PRD unit, the data used to calculate the risk value in the form of PRD data sheets include: general data, process condition data, data materials, data connection, and database and selection data, as well as inspection history records at the PRD unit (17 – PSV – 298) which are used to determine risk values, inspection plans, and recommendations for actions to be taken in mitigating risks. According to the calculation of the risk value on the PRD unit equipment (17 – PSV – 298) which was analyzed using the risk-based inspection method, the risk value for the PRD unit was 0.1135 m2/year, so it can be determined that the risk category is the medium category according to plotting against the risk matrix. The PRD unit (17 – PSV – 298) will approach the risk target as determined by the company in the 24th year since the first risk assessment was carried out using the RBI method and estimated on January 11, 2042. Based on the inspection history, there has been a leak in the PRD unit (17 – PSV – 298) during the pop test. Thus, the recommended type of inspection is the type of shop inspection/overhauls and is carried out periodically at least every 4 years. This is in accordance with PERMEN ESDM No. 32 of 2021 Article 21 Paragraph 4a.

Abstract

Chemical reduction with sodium thiosulfate is commonly used to dechlorinate chlorinated waste. U.S. Environmental Protection Agency recommends sodium thiosulfate (Na2S2O3) as a dechlorinating agent for waste samples containing residual chlorine before being released into the environment or entering the distribution system. However, sodium thiosulfate's efficiency and chlorination kinetics at different concentrations are still unknown due to a lack of information on chlorination kinetics. The study was conducted by determining the number of efficient doses of sodium thiosulfate and observing chlorination kinetics using sodium thiosulfate as a dechlorination agent observed at different stoichiometric ratios (1x, 1.5x, and 2x). Sodium thiosulfate at a stoichiometric dose of 2x can reduce chlorine residue by up to 0.4 ppm. The regression analysis of and constant rate are used in the kinetic analysis of sodium thiosulfate dechlorination processes. The kinetics of the chlorination process employing sodium thiosulfate is first order to the total concentration of chlorine in solution at a stoichiometric dosage of 2x, according to the findings.
