Limited land availability is a major constraint in developing school infrastructure in active urban educational facilities. This study evaluates the classroom development plan at SDN 39 Lubuklinggau from the perspective of a planner, focusing on land limitation, functional needs, safety, constructability, and long-term building performance. A descriptive-evaluative approach was applied through technical observation, document review, alternative assessment, weighted scoring, and risk analysis. The results indicate that horizontal expansion is constrained by limited open space and may reduce internal circulation, student activity areas, and emergency space. Three alternatives were compared: horizontal expansion, building rearrangement, and a two-storey classroom scheme. The two-storey alternative obtained the highest score of 84, compared with 61 for rearrangement and 56 for horizontal expansion. However, its feasibility depends on further soil investigation, structural design, staircase and evacuation safety, utility coordination, construction phasing, and strict site safety control. The study recommends that the planner prioritize detailed site measurement, geotechnical investigation, detailed engineering design, construction safety planning, and post-construction functional evaluation. A vertical classroom strategy can be considered a rational solution for land-constrained schools when supported by accountable technical planning and integrated project control.

This study aims to formulate an engineering strategy for water quality management and pollution control in the Tiku Sub-watershed, North Musi Rawas Regency. The study used a descriptive approach by integrating selected technical data from a dissertation-based assessment with semi-structured interviews involving 20 key informants representing technical agencies, village and subdistrict governments, community leaders, artisanal and small-scale gold mining actors, farmers, and riverbank communities. The analysis focused on water quality status, water availability and demand, pollution sources, perceived impacts, implementation constraints, and priority interventions. The results showed that the Tiku Sub-watershed is under significant environmental pressure. The average pollution index was 6.65, indicating a moderately polluted status, while mercury, cadmium, phosphate, and ammonia were the dominant parameters of concern. Surface water availability remained relatively adequate at 45,842,699.79 m3/year, and the average Criticality Ratio was 0.266; however, the water pollution carrying capacity was poor. Interview results indicated that mercury use and processing waste from artisanal gold mining were the most urgent issue (35%), followed by land-cover change and riparian degradation. The recommended strategy combines mercury-free processing technology, alternative livelihood development, cross-sectoral supervision, riparian rehabilitation, and transparent water-quality monitoring. The findings imply that watershed engineering should integrate technical, institutional, and socio-economic interventions.

Road improvement projects require consistency between technical planning documents and field implementation to ensure that service quality, structural performance, construction time, and user safety are achieved. This article evaluates the conformity between planning and realization in the Pangkalan-Batas Jambi road improvement project in Rawas Ulu District, North Musi Rawas Regency. The study used a descriptive-quantitative evaluative approach based on field monitoring, project technical documents, comparative quantity analysis between contract and Contract Change Order (CCO), and identification of implementation constraints. The results showed that several work items changed during construction because initial planning data did not fully capture actual field conditions. Quantities increased for drainage excavation (+18.87%), roadbed preparation (+8.99%), aggregate class A base course (+12.51%), and AC-Base (+11.98%). Conversely, reinforced pipe culverts decreased (-58.33%), unsealed aggregate base/sirtu decreased (-43.50%), and tack/prime coat volume slightly decreased (-0.47%). The time schedule showed a minor delay of -0.13% in the first week but recovered in the second week, indicating effective field coordination. Main constraints included traffic interference, limited worker visibility, and equipment visibility. The study recommends more detailed site surveys during planning, stronger traffic management, stricter occupational safety implementation, systematic progress control, and routine post-construction maintenance to maintain road service life.

Within the framework of Islamic family law (fiqh munakahat), the issue of nusyuz plays a significant role, as it is closely related to maintaining harmony and stability in the marital relationship. Generally, nusyuz is often defined as a form of a wife’s disobedience toward her husband. However, Islamic jurisprudence acknowledges that nusyuz can also be committed by a husband if he fails to fulfill the rights, responsibilities, and obligations he owes to his wife, in accordance with the principles of Sharia. This study aims to provide a comprehensive analysis of the concept of nusyuz in the context of family life, from the perspective of fiqh munakahat. The discussion covers the meaning and characteristics of nusyuz, its legal basis in Islamic sources, the factors contributing to its emergence, its various manifestations in married life, its implications for family relationships, and existing methods for addressing this issue. This study employs a literature review method supported by a descriptive qualitative approach, drawing on relevant literature from classical and contemporary Islamic legal sources. The results indicate that resolving issues of nusyuz should be approached through a gradual and constructive process, including counseling, dialogue, mediation, consultation, and reconciliation. These steps aim to restore mutual understanding and strengthen family unity. Therefore, raising awareness of each spouse’s rights and obligations is crucial to preventing nusyuz and creating a household filled with peace, love, mutual respect, and intimacy.

The rapid development of digital service platforms, particularly online motorcycle taxi services, has transformed modern economic transaction patterns, where the relationship between drivers and consumers is categorized as an ijarah (service lease) contract. However, in practice, various forms of breach of contract (wanprestasi) frequently occur and potentially harm one of the parties. This study aims to analyze the concept of the ijarah contract, identify the forms of wanprestasi, and review them based on Sharia Economic Law principles. This qualitative normative research employs a literature-based approach, utilizing secondary data from classical fiqh books, DSN-MUI fatwas, the Indonesian Civil Code, and reputable academic journals, which are analyzed descriptively-analytically. The findings reveal that breaches occur in three typologies: unilateral cancellation by consumers (ta'addi), negligence and fictitious account manipulation by drivers (taqshir and tadlis), and disproportionate cancel fee policies by platforms, indicating structural dzulm. From a sharia perspective, the settlement of wanprestasi requires compensation (ta'widh) calculated based on actual loss without riba elements, while classifying technical obstacles as force majeure under a fault-based liability approach. This study implies the need to reconstruct the digital ecosystem so that it is not only formally valid but also enforces substantive justice based on maslahah (public interest), al-‘adl (justice), mas,uliyyah (responsibility), and tawazun (proportional balance)

This research is motivated by the development of injection motorcycle engine management system technology that demands increased performance through optimization of the Electronic Control Unit (ECU). This study aims to analyze the performance comparison of the Yamaha MX King 180 cc using a standard ECU and a racing ECU on engine power and torque. The method used is an experiment with engine dynotest testing in the range of 6000-10000 RPM. The research sample is a 2015 Yamaha MX King unit that has been modified to 180 cc. Data were collected through direct measurements of power (HP) and torque (Nm), then analyzed descriptively in the form of tables and graphs. The results show that the racing ECU is able to produce a higher maximum power of 24.9 HP at 10000 RPM compared to the standard ECU of 22.2 HP at the same engine speed. In terms of torque, both types of ECU reach peak values ​​at 8000 RPM with a relatively small difference (18.18 Nm on the standard ECU and 18.15 Nm on the racing ECU). However, at low to mid-range revs, the racing ECU tends to produce slightly more torque, although at very high revs, it experiences a greater decrease compared to the standard ECU. The racing ECU excels at increasing high-rev power, while the standard ECU exhibits more consistent torque stability. Therefore, the choice of ECU type must be tailored to the performance requirements and the characteristics of the vehicle's use.
