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.

Creative writing plays an important role in developing students’ imagination, self- expression, and language competence in the digital era. However, many learners still struggle with generating ideas, maintaining motivation, and gaining confidence in writing. This study aims to analyze how the use of Wattpad, viewed through the Social Constructivist framework, can enhance students’ creative writing skills, motivation, and confidence. This research applies a qualitative descriptive approach supported by survey data from 30 high school students who actively use Wattpad.

PT. Tirta Fresindo Jaya, specifically its Pasuruan plant as the producer of Pucuk Harum Tea beverage, requires a large supply of steam to support various production processes. This steam is used in the process of heating tea leaves, heating water through a heat exchanger, and heating chemicals and water in the cleaning in place (CIP) process. Steam pressure of 5 bar that is flowed to the process equipment will undergo condensation to produce condensate. To separate steam and condensate, steam traps are used, consisting of several types, namely mechanical, thermostatic, and thermodynamic. However, in operational practice, steam trap malfunctions often occur, either in the form of steam leaks that are wasted with condensate or failure to drain condensate from the system. This condition causes a decrease in the efficiency of the steam piping system and increases the workload of the boiler. As a result, fuel consumption and boiler feed water requirements become greater than ideal conditions. Therefore, this study aims to analyze the energy and operational losses caused by steam trap malfunctions, as well as evaluate their impact on boiler system performance and steam utilization efficiency at PT. Tirta Fresindo Jaya Pasuruan plant.

This article explores legal accountability for flood disasters occurring in several regions of Sumatra, which are widely alleged to result from large-scale logging activities. The analysis is conducted within the framework of the Indonesian legal system, with particular emphasis on contract law. This study adopts a literature-based research method by examining statutory provisions, legal doctrines, and relevant scholarly publications. The analysis demonstrates that flood events should not be understood solely as natural occurrences, but rather as ecological consequences arising from the failure to fulfill contractual obligations embedded in forest utilization permits. From a contract law perspective, forestry concessions establish binding legal relationships that impose environmental protection duties on permit holders in accordance with the principle of pacta sunt servanda. Logging activities that exceed authorized limits may therefore be classified as contractual default (wanprestasi) and, at the same time, constitute unlawful acts that cause harm to the state and affected communities. Accordingly, this study underscores the necessity of strengthening environmental protection clauses within concession agreements and applying strict liability principles to enhance legal responsibility and prevent recurring environmental harm.

Sorghum (Sorghum bicolor L.) is an annual crop that is tolerant to drought and requires relatively low water input, making it suitable for cultivation on suboptimal lands such as peat soils. However, the utilization of peat soils for crop production faces major constraints, including high soil acidity and low availability of essential macronutrients, particularly nitrogen (N), phosphorus (P), and potassium (K). Improving the chemical properties of peat soils can be achieved through the application of dolomite to reduce soil acidity and NPK fertilizer to enhance nutrient availability. This study aimed to evaluate the growth and yield responses of sorghum to different combinations of dolomite and NPK fertilizer rates on peat soil and to determine the most efficient dosage. The experiment was conducted using a factorial randomized block design with two factors, namely dolomite rate and NPK fertilizer rate. Observations were made on growth and yield parameters of sorghum. The results showed that the interaction between dolomite and NPK fertilizer had no significant effect on all observed parameters. Based on efficiency analysis, the application of 1.16 kg dolomite per bed and 200 kg NPK per hectare was identified as the most efficient dosage to support the growth and yield of sorghum on peat soil. These findings indicate that appropriate soil amendment and fertilization management are essential for optimizing sorghum production on peat soils.
