This study was carried out at PT XYZ, a business involved in the oil and gas sector, located in Indramayu, West Java. The objective of this study is to identify and analyze the mental workload existing at PT XYZ by examining the Weight Workload (WWL) values. The research method used is NASA-TLX. The population for this study consists of 10 workers in the Delta 101 Tank Fabrication section at PT XYZ, totaling 10 individuals. Based on the study, the results of the mental workload calculations for the Delta 101 Tank Fabrication mechanics indicated that out of the 10 respondents, 2 mechanics were categorized as having a High workload. These mechanics are Mechanic 3, aged 53, Mechanic 5, aged 50, and Mechanic 8, aged 52, with a score of 90.7, which falls into the Very High category. The lowest score was obtained by Mechanic 7, aged 29, with a score of 77.3, categorized as High. The researcher provides suggestions for improvements that are expected to help the company address existing issues. The proposed improvements include recommending the addition of workforce; having additional personnel could reduce double job responsibilities, ensuring that installation and welding tasks are performed by different mechanics, thus optimizing the Tank Fabrication process.

The building to be utilized should undergo regular inspections and performance testing to determine whether it can function and operate according to its intended use. Compliance with administrative and technical regulations governing the utilization of buildings is demonstrated through the issuance of a Building Worthiness Certificate (SLF). This study aims to assess the compatibility of the building's function with the conditions during the planning phase and evaluate the structural feasibility of the building. It also seeks to implement the provisions of Government Regulation No. 16 of 2021 regarding the Implementation of Law No. 28 of 2002 on Buildings. Based on the research conducted, it can be concluded that the structural suitability of the MSC Indosat Baturaden building has changed compared to the planned building. Initially designed as a battery storage building, it is currently used as an MSC building or a facility for storing batteries and servers. Additionally, there are discrepancies in the area specified in the original Building Permit (IMB) compared to the current building. Further analysis of the building's structure and the application of current regulations regarding structural serviceability, including dynamic load analysis (earthquake), inter-story drift analysis, P-Delta analysis, and structural cross-section checks, concluded that the building is safe as it meets the requirements specified in SNI 1726:2019 and SNI 2847:2019. The highest structural cross-section capacity ratio was 0.2 < 1, and the inter-story drift value was 0.023 < 0.07. The existing concrete material meets the structural standards, with a characteristic compressive strength of 28.98 MPa. The results of the rebar scan detector test showed that the type of reinforcement used complies with the standards specified during the planning phase, referring to SNI 07–0408–1989. Overall, the structural analysis results for the MSC Indosat Baturaden building indicate that the building is safe and remains fit for use.    

This study explores the factors influencing attendance among employees enrolled in English language courses, with a focus on understanding attendance patterns and proposing interventions to improve participation. English proficiency is a critical asset in the global era, and many companies in Indonesia offer English courses as part of their professional development programs. Despite their importance, these programs face attendance challenges due to factors such as professional commitments and schedule conflicts. The research employs a quantitative method, utilizing surveys to gather data from 15 employees participating in English courses at two institutions in Indonesia, one in Jakarta (called Bravo – pseudonym) and another one in Bandung (called Delta – pseudonym). Results highlight two primary factors affecting attendance: (1) professional development as a key motivator and (2) schedule conflicts as a major barrier. To address these challenges, the study proposes actionable interventions, by implementing a blended learning model and integrating mutual agreements between companies and course providers including creating supportive environment such as implementing blended learning model, designating learning hours and providing reward or incentive.

Service quality significantly affects customer loyalty (β₂ = 0.319, t = 2.478, p = 0.014). Customer satisfaction significantly impacts customer loyalty (β₃ = 0.320, t = 2.690, p = 0.007). The marketing mix significantly influences customer satisfaction (β₄ = 0.453, t = 3.799, p = 0.000), and service quality significantly influences customer satisfaction (β₅ = 0.445, t = 3.830, p = 0.000).

The public health quandary in Indonesia encompasses the presence of Dengue Hemorrhagic Fever (DHF). DHF is frequently encountered in tropical and subtropical regions. The World Health Organization (WHO) has recorded Indonesia as the nation with the highest incidence of DHF in Southeast Asia. To avert DHF, it is imperative to engage in routine eradication of mosquito breeding grounds. Moreover, augmenting public cognizance and comprehension regarding DHF prevention through educational outreach is of paramount importance. The objective of this initiative is to ascertain the level of knowledge about DHF among students at SDN 18 Delta Pawan, Delta Pawan District, Ketapang Regency. The methodology employed includes lectures, discussions, and Q&A sessions, with a sample size of 35 respondents. The findings revealed that the students' knowledge at SDN 18 Delta Pawan fell into the High category for 12 students (34.3%) and the Low category for 23 students (65.7%). It can be inferred that this educational outreach was fairly beneficial in enhancing the students' knowledge about dengue hemorrhagic fever at SDN 18 Delta Pawan.

The advance of technology has affected many aspects of people’s lives. One field that also has been greatly affected by this advancement is Education. There are lots of online learning platforms that emerged in the past 2 decades. Khan Academy and IXL are two favourite examples of those platforms that are being used to help students learning Mathematics and Science. DeltaMath, although not as famous, is also of the platforms that are available and can be used to help students learning Mathematics. This study examined the impact of DeltaMath toward students’ Mathematics learning outcomes. There are 56 samples in total that are divided into 2 group of 28 students. One group is the group of students who are introduced to and are using DeltaMath as supplementary resources in their learning and the other group consisted of students that didn’t use the DeltaMath in their learning. Main findings show that: 1. The average score of the final exam of group who used DeltaMath is higher than the group of students that didn’t use DeltaMath. 2. Students who solved more than 150 questions in DeltaMath performed better in the final exam than most students, their average is 7 points higher compared to the average of all students. 3. There is no significant difference between group that are using DeltaMath compared to group of students who didn’t use DeltaMath. There are still few publications related to DeltaMath, unlike Khan Academy and IXL, thus, this study hopefully can contribute to the research of the impact of using DeltaMath.
