This study aims to determine and analyze service waiting times, identify the root causes of long queues, and develop a strategy to improve service performance at the 5361137-gas station (SPBU) at the Surabaya-Gresik Toll Rest Area. The research method used is a mixed-methods approach with an exploratory sequential design. This study combines quantitative analysis using Queuing Theory to measure system performance (arrival rates and service times) and descriptive qualitative analysis using a Fishbone Diagram. Data were collected through direct observation, interviews, and g-form techniques. The results indicate that the current queuing system performance is in a critical or severe condition, indicated by a server utilization rate of 0.94 to 1.02 during peak hours. The average time spent by vehicles in the system is 14.3 minutes, of which 9.6 minutes (67%) is spent waiting in the queue. Fishbone diagram analysis revealed that the root cause of the main problem lies in the complex interaction of factors: Machine factors (EDC signal failure and pump repair downtime), Human and Method factors (implementation of static shifts and reactive maintenance), and Environmental factors (narrow layouts that hinder large vehicle maneuvers). As a solution, this study formulated a hybrid improvement strategy that includes short-term business process engineering (the use of Floating Staff and lane segregation) and long-term investment in additional pumps to change the queuing model from Single Channel to Dual Channel. This strategy is expected to reduce the utility level to a safe zone below 0.80 with a target waiting time of 3–5 minutes.

Corrective maintenance is one of the maintenance strategies performed after system failures or malfunctions occur, particularly in diesel power plants (PLTD) that play a crucial role in supplying electricity to remote areas such as Jayapura. This study aims to identify the types of failures occurring in diesel engines at the Jayapura PLTD and to evaluate the corrective maintenance actions implemented. Data were collected through direct observation during an internship program, interviews with technicians, and analysis of historical maintenance and failure records. The results indicate that the most common failures occurred in the lubrication system, fuel system, and cooling system. Corrective actions included component repairs, spare part replacements, and system adjustments. The application of timely and appropriate corrective maintenance significantly reduced machine downtime and improved the reliability of the power generation system. This study recommends integrating corrective and preventive maintenance strategies to maximize operational efficiency of the PLTD.

Legal protection for consumers is a crucial element in the legal relationship between business actors and the public, particularly in high-risk service sectors such as gas stove repair services. In practice, many consumers still experience losses due to negligence by service providers, whether caused by inadequate technical handling or insufficient information regarding the condition of the stove after repairs. This study aims to identify and analyze the forms of legal protection available to consumers who suffer losses as a result of such negligence, as well as to determine the types of legal liability that may be imposed on gas stove repair service providers. Using a normative legal research method, this study applies both legislative and conceptual approaches. The legislative approach examines relevant laws and regulations concerning consumer protection, while the conceptual approach analyzes legal principles and expert doctrines related to liability. The findings indicate that consumer protection is provided in two forms: preventive protection, which ensures product and service safety in accordance with Indonesian National Standards (SNI), and repressive protection, which is implemented through enforcement mechanisms such as claims for compensation or dispute resolution through the Consumer Dispute Settlement Agency (BPSK) or the courts. Business actors who commit negligence in providing repair services can be held legally responsible based on the principles of negligence or strict liability. To strengthen consumer protection, the study recommends the establishment of derivative regulations concerning technician certification, standardized repair service procedures, and integrated supervision of safety compliance within the gas stove repair service industry.
