Abstract

Low labor productivity, weather dynamics, site changes, and material logistics constraints often trigger delays and cost overruns on PT SMJ's large-scale construction projects. This phenomenon underscores the importance of a comprehensive evaluation of operational control efficiency. This study focuses on analyzing project performance in terms of timeliness, budget availability, and resource procurement effectiveness. The methodology was systematically implemented through a questionnaire survey of 150 expert respondents, followed by statistical modeling using SmartPLS-based Structural Equation Modeling (SEM). Quantitative test results indicate that this model has a high fit, with an SRMR value of 0.045 and an NFI of 0.945. Path coefficient evaluation demonstrates that the budget has a very strong positive and significant influence on project performance, with an original sample value of 0.796 and a T-statistic of 6.368. Furthermore, resource procurement is listed as the most dominant determinant influencing budget stability, with a path coefficient of 0.834. The main conclusion of the study confirms that successful construction project performance relies heavily on the accuracy of operational budget management. Strict supply chain oversight and the use of the critical path method are recommended to mitigate the risk of delays and optimize financial efficiency in the field.

Abstract

Keterbatasan infrastruktur telekomunikasi di wilayah 3T menyebabkan rendahnya kualitas konektivitas digital dan berdampak langsung pada layanan publik. Hasil pengukuran awal di Kabupaten Simalungun menunjukkan kekuatan sinyal sangat lemah (< -85 dBm) pada sekolah, puskesmas, dan permukiman warga, sehingga akses internet hampir tidak dapat dimanfaatkan secara produktif. Kegiatan pengabdian ini bertujuan meningkatkan konektivitas desa melalui implementasi modul pemancar sinyal berbasis mesh Wi-Fi dengan Starlink sebagai sumber internet utama. Metode pelaksanaan meliputi observasi lapangan, pengukuran kecepatan menggunakan Speedtest, instalasi perangkat, serta pelatihan literasi dan manajemen jaringan kepada 40 peserta dari unsur perangkat desa, guru, tenaga kesehatan, pemuda, dan kader digital. Hasil implementasi menunjukkan peningkatan signifikan kecepatan internet hingga 150 Mbps di Kantor Desa dan lebih dari 70 Mbps di titik layanan lainnya. Peningkatan ini secara langsung mengubah kualitas layanan publik: pembelajaran daring di sekolah dasar dapat berjalan stabil, layanan puskesmas dan administrasi desa jarak jauh mulai dimanfaatkan. Selain itu, konektivitas yang lebih andal mendorong UMKM lokal untuk memanfaatkan marketplace digital. Indeks efektivitas layanan publik dan ekonomi meningkat lebih dari 60%, dengan tingkat kepuasan masyarakat mencapai 95%. Temuan ini menegaskan bahwa peningkatan konektivitas bukan hanya persoalan teknis, tetapi menjadi katalis transformasi layanan publik dan pemberdayaan ekonomi desa.

Abstract

Indonesia's nickel processing industry plays a strategic role in the global economy, yet fatal occupational safety incidents continue to plague the sector. This study aims to examine in-depth allegations of ethical violations in the PT Indonesia Tsingshan Stainless Steel (ITSS) smelter furnace explosion tragedy in Morowali on December 24, 2023. This study uses a descriptive qualitative method with a case study approach, analyzing secondary data through the lens of the Indonesian Engineers Association (PII) Code of Ethics and the Swiss Cheese Model accident investigation theory. The analysis reveals serious violations of the Catur Karsa principles, particularly the obligation to prioritize public safety. These failures are systemic, involving negligence in risk management, oversight of repair procedures (hot work), and the dominance of production interests over safety. This study recommends reforming the occupational safety and health culture by strengthening the authority of professional engineers and enforcing strict ethical sanctions.

Abstract

This study aims to examine in depth the implementation and violations of the engineering code of ethics in the Hambalang National Education, Training, and Sports School (P3SON) Project. The Hambalang Project, which experienced structural failure due to neglect of geotechnical engineering principles and political collusion, is used as a case study of systemic failure. The analysis focuses on violations of the Sapta Dharma of the Indonesian Engineers Association (PII) and the evaluation of professional responsibility based on ethical theories (Deontology, Teleology, and Virtue Ethics). The analysis results indicate that ethical violations, especially conflicts of interest and systemic corruption, are the main causes that trigger technical violations (ignoring the risks of expansive clay soil). The identified fundamental violations are Sapta Dharma Point 1 (Prioritizing Public Safety), Point 2 (Working According to Competence), and Point 4 (Avoiding Conflicts of Interest). Recommendations proposed include systemic solutions such as the separation of critical contracts and mandatory independent design validation (peer review) to strengthen the culture of engineering ethics.
