Abstract

This study aims to design the wastewater utility system (blackwater and greywater) for SMP Negeri 4 Tagulandang building, which is part of the permanent housing relocation project following the Mount Ruang eruption in Modisi Village, South Bolaang Mongondow Regency. A descriptive quantitative case study method was employed with technical calculations based on SNI 8153:2015, SNI 03-7065:2005, and SNI 2398:2017. User data of 32 people (23 students, 8 teachers, and 1 principal) served as the basis for clean water demand and wastewater generation calculations. Results show blackwater discharge of 960 L/day (0.0444 L/s) and greywater of 320 L/day (0.0148 L/s) with a total peak discharge of 0.145 L/s. Piping network design using the Plumbing Fixture Unit (UBAP) method resulted in Ø4" (110 mm) pipes with 1% slope for blackwater and Ø3" (75 mm) pipes with 2% slope for greywater. The designed separate septic tank capacity is 7.68 m³ with dimensions of 2.77 m × 1.87 m × 1.79 m. The system meets hydraulic requirements and applicable technical standards, ensuring safe and sustainable operation.

Abstract

Student housing blocks are used intensively and funded from institutional budgets, yet their maintenance often begins only after something breaks. This article reviews nineteen studies published between 2019 and 2026, selected through a documented search of Google Scholar and Garuda with explicit inclusion criteria, to identify the technical, economic, and management factors linked to maintenance performance, and proposes a conceptual model for Student Housing X. Technical and management factors each appeared in 10 studies, economic factors in 8, and user-side outcomes in 5. Economic aspects were measured either as budget availability or as separate life cycle cost calculations, never as long-term cost practice. In the draft instrument, two economic indicators duplicated two performance indicators, and only ten of 22 indicators measured practice. The refined model uses 19 resident-observable indicators, three reflective factors and a formative performance construct, while documents and budget projections are verified with managers outside the structural model. Present-value life cycle cost per component group is then combined with importance-performance map analysis to rank interventions for the maintenance SOP. The model and its hypotheses have not yet been tested empirically.
