Abstract

The clean water needs of the community, both domestic and industrial, in the cities of Banjar and Banjarbaru Regency are provided by the Intan Banjar Regional Drinking Water Company in collaboration with PT. Drupadi Tirta Intan who uses the Martapura river as a source of raw water. PAC is a coagulant commonly used in water treatment. PAC influences the size of production costs. This research aims to obtain PAC chemicals that are effective, efficient and in accordance with the characteristics of PT Drupadi Tirta Intan's WTP, so that Syarkawi WTP operators can easily operate the IPA using PAC chemicals when raw water turbidity is high or low. The chemical application process is good, namely the Jartes and Plant Test processes. To compare the parameters of the Jartes test and plant test, the author used the statistical method Analysis of Variance (ANOVA) to find out whether the two products had good performance. From the research results, it was found that both PAC products from PT A and PT B could be used as coagulants for the Syarkawi IPA Water Treatment Plant unit, however the level of effectiveness and price efficiency of the products from PT B was better.

Abstract

The purpose of this study is to investigate the impact of implementing procedures and monitoring functions on vessel safety at Nunukan Port. This study uses a quantitative approach using the smart partial least squares (PLS) method. This method analyzes quantitative data and models the relationships between the variables involved in the study. The study results were obtained by analysis using the Smart PLS method. First, there is a positive correlation between the implementation of effective management procedures at Port Nunukan and the level of vessel safety. This means that the better the control procedures are implemented, the higher the level of vessel safety that can be achieved. In addition, the study found that proper training of port personnel has a positive impact on vessel safety. A port officer with sufficient knowledge and skills to carry out their supervisory duties can significantly improve the safety level of vessels in Nunukan Port. Furthermore, the study shows that coordination among the various actors involved in maritime management, such as authorities, port officials and ship owners, also has a positive impact on vessel safety. Proper cooperation of all involved will increase the effectiveness of supervision and reduce the risk of accidents.

Abstract

The development of technology and the challenges of the times that are getting bigger with the dissemination of information that is so massive can affect the formation of the character of the younger generation so that a program is needed that can shape the character of the younger generation. Character education is an important alternative solution that can be implemented in the era of globalization given the rapid flow of information and the influence of foreign cultures that are increasingly unstoppable with digital technology. One alternative that can be implemented to be able to carry out character education is Interprofessional Education (IPE), which has been widely applied in the world of health. This article provides a conceptual framework for how Interprofessional Education (IPE) can be developed and applied in character education because the basic competencies contained in Interprofessional Education (IPE) have values ​​and principles that are in line with character education. In this article, the author explores the values ​​and principles in Character Education in the Interprofessional Education (IPE) program.

Abstract

Forklifts are vital assets in industrial logistics systems, especially in material handling and loading and unloading activities in Warehouse and Jetty areas. High availability is an essential factor to ensure smooth operations and supply chain efficiency. This study aims to analyze the 2014 Komatsu FD25C-17 SN: FA15 forklift and determine the optimal preventive maintenance interval to maximize equipment availability. The research method employs an acoustic analysis approach, utilizing historical maintenance data from the period 1 January 2025 to 30 June 2025. The data is used to calculate the Mean Time Between Failures, Mean Time To Repair, and actual availability. A goodness-of-fit test is carried out to determine the best distribution probability, and the results show that the lognormal distribution best fits the smallest Anderson-Darling value (2.055 and 1.713). Based on the lognormal distribution parameters, a preventive maintenance interval simulation was conducted to find the optimal point (Topt), considering a minimum reliability of 49% and a maximum downtime of 18 hours. The simulation results show that the optimal maintenance interval was achieved at 224 hours of operation, with an availability value increasing from 89.71% to 92.32%. Although there was a slight decrease in the reliability value from 49.42% to 49.15%, this value was still within acceptable limits. This study concludes that implementing the Reliability-Centered Maintenance approach, based on lognormal distribution analysis, significantly increased forklift sales and availability. It can serve as a practical reference for making data-based maintenance policy decisions in the logistics industry.
