Abstract

Congregations are social entities that require a sense of community to function effectively. One of the most prominent locations for community engagement is the church. The diverse needs of congregants drive their attendance at church, including worship, social interaction, and spiritual growth. To fulfill these needs, churches offer a wide range of programs. To effectively address these needs, churches must have a clear understanding of the requirements of their congregants. A church management information system (CMIS) provides insight into the congregation's needs, enabling church leaders to comprehend their congregants' requirements and develop a strategic plan. The XYZ Church CMIS and data governance were developed based on a comprehensive literature review and input from IT professionals engaged in group discussions. This research's objective was to develop a CMIS to collect and manage data on the congregation and church. The insights from the CMIS have enabled church leaders to adjust event schedules. Prior to the implementation of the CMIS, the average attendance at events was below 20%. A review of the CMIS data over a 12-month period, in conjunction with the insights gained from group discussions with church leaders, revealed that event attendance had risen to above 70%. The church management information system has proven to be an effective tool for church leaders to create strategic plans for event scheduling, resulting in increased event attendance. In future research, it would be beneficial to consider not only enhancing event attendance but also increasing the number of congregants

Abstract

Sanitation infrastructure is intended to complement the needs of people who do not yet have access to wastewater infrasctucture include bathing, washing and toilet. Inadequate sanitation infrastructure in an area can cause problems of decreasing environmental quality in residential areas. Based on data from Ciamis Regency in Figures for 2022, it is stated that the population growth rate is 0.94%, this is one of the problems arising from the rapid population growth and various activities carried out, especially sanitation issues, which are related to domestic wastewater treatment including bathing, washing and toilet bathing facilities or Mandi, Cuci, Kakus (MCK). Ciamis Regency has a total of 63 MCKs that have been built in the 2010-2022 period, spread across 19 sub-districts and 62 villages with 63 MCK units. The results of the assessment of the functioning of the MCK infrastructure in Ciamis Regency show that 37 MCK units are in prime condition, 23 MCK units are damaged but can still function properly, 3 MCK units where users are hesitant to use the MCK. Efforts need to be made to repair damaged and/or non-functioning MCKs by increasing participation from the user community in the form of contributions to MCK managers. This is with the aim that people want to reuse and care for MCK as a form of sense of ownership and shared responsibility.

Abstract

Data analysis is essential for gaining insights and making informed decisions. A crutial step in data analysis is data processing, which involves preparing and filtering raw data to ensure accuracy, consistency, and structure. While Microsoft Excel is commonly used for data processing, it is susceptible to human errors and has limitations in handling large datasets. Python provides an alternative by automating data processing through scripts executed by the interpreter. The superior software for data processing is obtained by comparing the computer resource utilization based on statistical theory approach, Wilcoxon signed-rank test. This test is appropriate because it does not require the assumption of a normal distribution, providing flexibility in comparing computer resource utilization between Microsoft Excel and Python. Microsoft Excel and Python proceed *.csv and *.xlsx files, then Task Manager recorded the data of computer resource utilization for each processing step. The Wilcoxon signed-rank test analyzes the data and evaluating two hypotheses. H0 (there is no any significant differences in computer resource utilization between Microsoft Excel and Python are calculated for each data processing) and H1 (there is significant differences in computer resource utilization between Microsoft Excel and Python are calculated for each data processing). The sum of ranks in Wilcoxon test are compared to the critical value from the Wilcoxon distribution table to determine the accepted hypothesis. Based on the Wilcoxon test results, hypothesis H1 is accepted, indicating a significant difference in computer resource utilization between Microsoft Excel and Python.

Abstract

The square root number of two is an irrational number. If it is an irrational number, the result cannot be written as a fraction of the numerator and denominator. Fractions that approach the square root value of two have a correlation with Goen's A-B numbers. The regularity of the A-B Goen number sequence can be formulated into the A-B Goen function which is built from the Ivan Newton series. In this research, it can be proven that the A-B Goen function from the Ivan Newton (IN) series is computationally more effective and efficient when compared to the A-B Goen generating function in producing A-B Goen numbers which in infinite sequence will approach the square root value of two.
