Enhancing Software Developer Selection with Integrated F-AHP and F-TOPSIS Techniques

Murnawan Murnawan — 2024-07-09

This study focuses on enhancing the selection process for software developers by integrating the Fuzzy Analytic Hierarchy Process (F-AHP) and the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (F-TOPSIS). The primary objective is to address the uncertainties and ambiguities in determining evaluation criteria and weights, thereby facilitating accurate decision-making when faced with multiple criteria and alternatives. Conducted within a software development company in Bandung, Indonesia, the study involved evaluating ten potential candidates for the software developer position. The methodology employed F-AHP to assess the importance of each criterion through pairwise comparisons, and F-TOPSIS to rank the candidates based on these criteria weights. The results revealed that Candidate CK-7 exhibited the highest closeness coefficient (CC_i), making them the top candidate, while CK-4 ranked the lowest. This integrated approach provided a systematic and transparent framework for decision-making, demonstrating its effectiveness in optimizing recruitment processes. The study contributes to the field by offering a robust decision-making tool that can be adapted to various industries, ensuring the selection of high-quality employees who meet necessary competencies, thereby improving overall productivity and performance.

E-Government Maturity Model Based on SPBE at Department of Spatial Planning and Development

Endang Amalia — 2024-07-20

Sistem Pemerintahan Berbasis Elektronik known as SPBE is a government administration that utilizes information and communication technology to provide services with the aim of realizing clean, effective, transparent, and accountable government governance, quality, and trustworthy public services. Because he role of ICT in supporting work processes and services in achieving the vision and mission of the Regional Government of West Java Province is very important, it is necessary to evaluate the use and implementation of ICT solutions for continuous improvement in all Regional Apparatus. In the department spatial planning and development, e-government maturity measurements are carried out in 4 domains (application, infrastructure, information security and IT governance and) by adopting a descriptive research method using questionnaire data with a scale of 5 likers. The results showed the evaluation of the maturity of the SPBE in department spatial planning and development obtained a “Very Poor” category with a total index value of 0.61. This research also provides recommendations and considerations in making decisions on how to take policies in implementing e-Government Implementation in the community development service to determine the development priority scale from the level of maturity.

Revealing Consumer Preferences in the Fashion Industry Using K-Means Clustering

Feri Sulianta — 2024-08-15

The fashion industry, driven by rapidly shifting e-commerce trends and consumer preferences, demands precise data analysis to optimize marketing strategies and enhance customer satisfaction. This study utilizes data mining techniques, specifically K-Means Clustering and the Elbow Method, to reveal consumer preferences within a dataset of 1,000 fashion product sales records, which include attributes such as product ID, name, brand, category, price, rating, color, and size. By grouping data into distinct clusters based on price and rating preferences, the analysis uncovers four key consumer segments. The optimal number of clusters is confirmed using the WCSS (Within-Cluster Sum of Square) method. These insights offer valuable guidance for refining marketing strategies in the fashion industry. Future research should consider additional variables and employ advanced tools for deeper analysis.

Techno-Economic Analysis of Blue Methanol Production from Natural Gas with Carbon Capture in Indonesia

Samuel Pangeran Aletheia — 2024-08-24

Methanol market in Indonesia is projected to grow with Compound Annual Growth Rate of 3.2% by 2034. Utilizing natural gas as a feedstock and employing carbon capture and storage technology using activated metildietanolamin with piperazine (MDEA-PZ), the process is designed to produce methanol with a low carbon footprint. The process design and simulation were carried out using Aspen HYSYS, focusing on mass and energy balances across pre-treatment, syngas formation, methanol synthesis, purification and carbon capture stages. The pilot-scale plant with a capacity of 100,000 tons per year located in the Special Economic Zone (KEK) Arun, Aceh, demonstrating promising results with an Internal Rate of Return (IRR) of 11.73%, a Net Present Value (NPV) of USD 166.63 and levelized cost of methanol (LCOM) of 611.61 $/ton MeOH. Compared to other low emission chemical plant, this plant offers promising economic feasibility.
