Abstract

This research aims to analyze the implications of conflicts of interest in procurement activities within Indonesian government institutions, focusing on motives such as personal gain, nepotism, and political influence on Procurement Committees. The study conducted interviews with seven procurement committees in a government institution in Indonesia. The findings indicate that the acceptance of personal gain significantly affects the procurement process, as the authority held by procurement committees provides opportunities to exploit gaps in each procurement process. Additionally, nepotism leads to biased decisions by the procurement committee, resulting in deviations from established procedures. Meanwhile, political influence on procurement committees, both directly and indirectly, poses a risk of intervention that disrupts the procurement process from planning to the determination of winners. Furthermore, based on Cause-Effect Diagram analysis, it was found that factors such as low individual moral principles, suboptimal inherent supervision, and the lack of stringent sanctions against fraudulent actors are the main triggers of conflicts of interest in the procurement process. Proposed improvements include the implementation of moral principles to encourage individuals involved in procurement to prioritize institutional interests and the involvement of internal supervisors in every stage of the procurement process to help identify signs of fraud or "red flags" that arise during the process.

Abstract

Cyber security is paramount to the sustainability of higher education institutions as more institutions move their information system to the cloud and allow stakeholders to access their information technology services from on-campus WIFI and mobile devices. This study aims to understand Indonesian higher education's current cyber security landscape by analyzing recent cyber-attacks that hit all sectors, notably higher education. Recent news articles and government reports related to cyber-security were analyzed using document analysis. This study found that data theft attacks were the number one cyber threat that higher education institutions faced, followed by attacks on institutional websites, social media pages, and personal mobile devices. This study found that the nature of recent cyber-attacks was consistent with the assessment posed by previous literature that stakeholders’ recent level of ability in cyber-security is not where it is supposed to be. The potential impact of future cyber-attacks on institutions and stakeholders is significant, underscoring the importance of this new understanding, which can help institutions prepare their stakeholders better to mitigate such threats.

Abstract

This study presents a structured framework for supply chain performance evaluation by integrating the SCOR model with the Analytical Hierarchy Process (AHP) and Fishbone Diagram. The approach is applied to PT. XYZ, an Indonesian pharmaceutical company recently entering the medical device distribution sector. The objective is to demonstrate how combining these methods can enhance the accuracy and depth of supply chain diagnostics. SCOR Level 1 identifies performance gaps, AHP in Level 2 prioritizes improvement areas, and Fishbone in Level 3 explores root causes. Rather than focusing solely on outcome metrics, the study emphasizes how method integration enables clearer identification of performance issues and actionable priorities. Results indicate that reliability, responsiveness, and agility are the most pressing concerns, primarily due to workforce limitations, digitalization gaps, and planning inefficiencies. This integrated approach provides deeper insights, better alignment between strategy and operations, and more targeted recommendations. It offers a practical and replicable model for organizations operating in highly regulated or transitional industries.

Abstract

This study used sentiment analysis and text mining on the user reviews of the Lelang Indonesia mobile application, specifically focusing on the ratings and reviews on the Google Play Store for the past six years. Sentiment analysis was performed by manually categorizing the data according to user review scores (positive or negative) and subsequently classified using the Support Vector Machine technique to assess accuracy levels. Various text mining approaches were employed to extract details regarding the issues or problems encountered by users. The study found that numerous Lelang Indonesia mobile application users encounter barriers that adversely influence their evaluation of public service quality, as seen by the attitude expressed in their reviews. The analysis of these reviews revealed several concerns, mainly regarding technical applications and service business procedures that require attention and follow-up from institutions. The study's findings can offer institutions a means to evaluate the quality of auction services delivered via mobile applications and serve as a basis for proactively enhancing these services to align with user expectations. This study enhances the understanding of mobile application-based public service satisfaction evaluation, enabling public institutions to evaluate these services in real-time by analyzing user sentiment from reviews.

Abstract

Penelitian ini bertujuan untuk menganalisis makna yang terkandung dalam lirik lagu Anakku Naburju dengan menggunakan pendekatan semiotika Roland Barthes. Lagu ini dipilih karena merupakan salah satu bentuk sastra lisan dalam budaya Batak Toba yang kaya akan nilai-nilai moral, emosional, dan spiritual. Metode yang digunakan adalah deskriptif kualitatif dengan teknik analisis semiotik yang meliputi tiga level: denotasi, konotasi, dan mitos. Hasil penelitian menunjukkan bahwa secara denotatif, lirik lagu ini menyampaikan pesan kasih sayang dan dukungan orang tua kepada anaknya yang sedang merantau atau menuntut ilmu. Pada tingkat konotatif, ditemukan makna yang lebih dalam seperti kekuatan mental, doa sebagai penguat spiritual, dan kecemasan orang tua dalam melepas anaknya. Sementara itu, pada level mitos, lagu ini merepresentasikan pandangan hidup masyarakat Batak, antara lain pentingnya perantauan, peran doa, serta nilai kekeluargaan dan kebersamaan. Lagu Anakku Naburju tidak hanya berfungsi sebagai sarana hiburan, tetapi juga sebagai media pewarisan nilai budaya antar generasi. Melalui analisis semiotika, penelitian ini menegaskan bahwa teks lagu dalam masyarakat tradisional memiliki peran penting dalam membentuk identitas budaya dan menyampaikan ideologi sosial. Dengan demikian, lagu ini merupakan refleksi dari struktur nilai dan pandangan hidup masyarakat Batak Toba yang tetap relevan hingga kini.

Abstract

This study examines the legal requirements governing foreign capital investment in the industrial sector in Indonesia. This study uses a normative legal approach. The data collection technique in this study is through literature studies. The data that has been collected is then analyzed in three stages, namely data reduction, data presentation and drawing conclusions. The results of the study show that the requirements for foreign capital investment in the industrial sector in Indonesia are regulated in Article 5 of Law Number 25 of 2007. Foreign Investors are required to be in the form of a limited liability company and must be located within the territory of the Republic of Indonesia, unless otherwise regulated by law. Investors, both domestic and foreign, can invest in the form of a limited liability company. Foreign Investors are only allowed to carry out business activities in large sectors with an investment value exceeding IDR 10,000,000,000.00 (ten billion rupiah), excluding the value of land and buildings. In addition, they must also complete the licensing or establishment documents required for foreign investors. Strong legal protection is needed to create a comfortable atmosphere for foreign investment in the Capital City of the Archipelago (IKN). The regulations applied must maintain the sovereignty of the nation and not betray the values adopted by the state. Effective legal protection will provide certainty and trust for foreign investors, so that they can contribute positively to economic growth and infrastructure development in Indonesia.

Abstract

In the digital transformation era, enterprise architecture (EA) is critical in aligning IT capabilities with organisational strategies. This study explores the impact of EA on employee performance management and its contribution to organisational benefits. Using a resource-based theoretical framework, the study develops a model integrating IT capability and business governance as predictors of employee performance and organisational outcomes. Data were gathered from 56 HR, IT, and executive professionals in organisations that have implemented IT-based performance management systems. Partial Least Squares Structural Equation Modeling (PLS-SEM) using SmartPLS 4.1.1.1 was employed to analyse the data. The findings demonstrate that both IT capability and business governance positively and significantly affect employee performance management, which in turn influences organisational benefit. The results underscore the importance of high-quality EA services in driving strategic HR outcomes. The study contributes to bridging the gap between technical EA implementation and its practical utility in human resource management.

Abstract

The Indonesian automotive industry, a key economic driver, faces intense competition, with Multi-Purpose Vehicle models dominating due to their suitability for large families and challenging road conditions. This study aims to evaluate the operational and marketing efficiency of seven Multi-Purpose Vehicle models from Brand T, marketed from January 2023 to June 2024, to strengthen market strategy. Using the Data Envelopment Analysis method with an input-oriented Charnes, Cooper, and Rhodes model, the analysis incorporated inputs like marketing, sales, trial unit, and training costs, and outputs including sales volume, market share, and gross profit. Findings reveal that five models achieved maximum efficiency (1.00), with the Multi-Purpose Vehicle segment averaging 0.90, outperforming sport utility vehicles, hatchbacks, and sedans. This efficiency stems from alignment with Indonesia’s socio-economic needs, including price sensitivity and demand for durable, high-capacity vehicles. The study concludes that Brand T should prioritize resource allocation and innovation in Multi-Purpose Vehicles, repositioning less efficient models and using them as branding substitutes for halo cars. These strategies enhance profitability and competitiveness in Indonesia’s price-sensitive market, reinforcing Multi-Purpose Vehicles as a strategic cornerstone.

Abstract

This research examines the impact of digital transformation on banking risks, specifically focusing on credit risk (NPL), liquidity risk (LDR), and insolvency risk (Z-score). Employing a quantitative method, the study constructs a digital transformation index using text-mining techniques applied to annual reports of Indonesian commercial banks. The analysis utilizes Ordinary Least Squares (OLS), Fixed Effects (FE), and the System Generalized Method of Moments (SYS-GMM) on a dataset comprising 59 commercial banks in Indonesia from 2018 to 2024. The results reveal that digital transformation significantly raises credit risk. In contrast, its effects on liquidity and insolvency risks are statistically insignificant, suggesting potential improvements in credit evaluation through the use of enhanced data and technological tools. Additionally, the study demonstrates the utility of the SYS-GMM model in addressing endogeneity concerns in dynamic panel data. These findings can help regulators understand the strategic role of digital implementation and innovation in enhancing risk management and financial stability within the commercial banking sector.

Abstract

Background: In insolvency restructuring under PKPU, a fundamental tension exists between the collectivity principle and the protection of secured creditors’ proprietary rights. The Indonesian Insolvency Law lacks explicit mechanisms such as the best-interest-of-creditors test, adequate protection, or differentiated creditor classification, mechanisms proven effective in comparative legal systems (Germany, Netherlands, United States). Objective: This article examines the legal implications of a homologation decision in Suspension of Debt Payment Obligations (PKPU) on separatist creditors who reject a principal debt reduction. Methods: This research uses a doctrinal legal research methodology, focusing on the examination of norms, principles, legislation, and legal doctrines through interpretation and systematic analysis. Results: The analysis focuses on three issues: (1) the juridical legitimacy of including a principal debt haircut in a homologation decision against non-participating separatist creditors; (2) the tension between the principle of collectivity in PKPU and the principle of consensualism in contract law; and (3) a model of balanced legal protection for separatist creditors within the framework of Indonesian insolvency law. The case studies used are the Homologation Decision of PT Bahtera Niaga Indonesia (Number 408/Pdt.Sus-PKPU/2020/PN.Niaga.Jkt.Pst) and the Supreme Court Judicial Review Decision Number 10 PK/Pdt.Sus-Pailit/2022. Conclusion: Although a homologation decision is normatively binding on all creditors based on the principle of lex specialis under insolvency law, the application of a haircut to separatist creditors is limited by the best-interest-of-creditors test principle and must not result in the separatist creditor receiving a value lower than the realization value of their collateral.
