Abstract

Computer-based test or assessment has been used widely, especially in the current COVID-19 pandemic, where many schools are conducting distance learning as well as distance examination. The need for a computer or software system to support education is inevitable. A range of solutions, from the free/open source software systems to the paid/proprietary ones have been publicly available. Still, an organization with limited resources prefers to find free or low-budget, while yet demanding reliable solutions. We have reported the use of the computer-based test in a new student recruitment test which is held country-wide. We developed the system based on TCExam, a free and open source computer-based test software, and successfully fulfilled the requirements, but with some tweaks. We found that the TCExam has a performance degradation when used by a large number of examinees concurrently, especially during specific phases during the test. This paper reports the result of our investigation to address the problem and suggests some modifications to the base codes as well as a recommendation of the hardware configuration. We evaluated the modified system in a simulated environment. We successfully achieved up to 56% performance gain using the modified system.

Abstract

As a higher education institution, Politeknik Statistika STIS also faces the same problems as universities in general, those are student failing to compare that year courses thus have to repeat those courses or student dropping out. To overcome this problem, this research proposes a Dropout Early Warning System (DEWS) that can provide early warnings for dropouts and repeat a class. With this system, it is hoped that it can help institutions to identify students who have the potential to drop out or repeat a class. The purpose of making this system is to help academic supervisors and decision makers from Polstat STIS in knowing the potential for student. The potential for students to drop out and repeat a class is measured by a potential score obtained from the results of an assessment of 5 criteria consisting of GPA scores, gender, economic factors, violation points, and record of repeating class. Prediction results are presented in three categories consisting of low potential, medium potential, and high potential which are calculated from the results of weighting calculations using the Analytical Hierarchy Process (AHP). The system is tested and verified using Black Box test and the evaluation of the calculation method using confusion matrix. Based on the test results, the functions that exist in the system can function properly and can supply the needs.

Abstract

Regulations in the Politeknik Statistika STIS (hereinafter called Polstat STIS) aims to produce graduates who are qualified, with integrity and trusted. In enforcing regulations in Polstat STIS, there are a student squad of regulations enforcement, which is called Satuan Penegak Disiplin or SPD in Indonesian, which aims to maintain the order, discipline and student ethics during their activities on and off campus. In upholding the regulations, SPD carries out surprise inspection and during the weekly morning assembly to check completeness and tidiness of student’s uniform as well as his/her look. However, previous research related to the student’s commitment to the campus regulations shows that half of the students have low commitment. This is partly due to the lack of supervision of students. Therefore, it is necessary to monitor the discipline and neatness of students on an ongoing basis. In order to conduct the monitoring and inspection on a more regular basis, the method of image recognition can be used to assist in overseeing student discipline and neatness. In this study, we developed a system which can detect in a real-time manner the completeness of attributes the student wears. The system we developed uses object detection to detect the completeness of student attributes. The system shows and records student(s) whose attributes are incomplete. The system expected to improve the discipline and neatness of the students.

Abstract

Data from censuses and surveys conducted by the Central Statistics Agency are urgently needed in various fields, one of which is in projects carried out by government agencies or researchers. The purpose of this research is to build a system that is used in microdata processing. This system provides microdata access to data users but users do not get these microdata files which can be taken home and cannot be accessed at any time through the user's device. Users can only do processing and get output from microdata processing. At the implementation stage, two applications were produced in the BPS DataLab system, namely applicationswebsite and desktop applications. Applicationwebsite used for account requests and requestsproject. Desktop applications are used to limit the user's time in processing data, triggers to start screen recording and restart the computer, and upload files resulting from data processing. Based on the research results, it can be concluded that the BPS DataLab system has fulfilled the research objectives

Abstract

Statistics Indonesia, known in Indonesia as Badan Pusat Statistik (BPS), has conducted a series of trials to utilize Computer-Assisted Personal Interview (CAPI) in a census or survey. However, CAPI costs a lot of money to procure and maintain the device. Bring Your Own Device (BYOD) principle offers cost opportunity to device management. In the practice of BYOD in BPS, a device that has good performance is required, because some devices aren’t capable of running CAPI properly. Yet, in BPS there is no standard value to qualify mobile devices to be used in census or survey. Therefore, it is necessary to review what kind of device is suitable for using CAPI. This study utilized CAPI used in a student’s field study as a case study reference. Initially, researchers develop benchmark applications as a tool for feasibility. Furthermore, developed application is tested on a certain base device to calculate the scores to be used as the standard values.

Abstract

The simplification of the organizational structure by BPS-Statistics Indonesia aims to form a simpler institution to support performance more effectively and efficiently. Challenges arise in the implementation of this simplification at Statistics of NTB Province, particularly with the division into several work teams leading to activity overlap. As a solution, it can be considered to develop an information system. The data collection method used involves interviews and observation, while system development follows the prototype model in the Software Development Life Cycle (SDLC). System evaluation was carried out using the Post-Study System Usability Questionnaire (PSSUQ). System development has gone through three iterations according to user needs and test results show the system is ready for use. After system integration on the server and system handover, an evaluation of system usability is carried out with PSSUQ. The evaluation results show that overall, the system provides good use for Statistics of NTB Province.

Abstract

Micro-enterprises play a vital role in Indonesia’s economy but continue to face persistent barriers in adopting information and communication technology (ICT). Understanding E-Readiness is essential for implementing effective digital interventions, especially for micro-enterprises. To address the lack of validated frameworks for assessing digital readiness at the micro-enterprise level, this study develops and empirically tests a novel E-Readiness Assessment Framework specifically designed for micro-enterprises. The proposed conceptual model consists of four dimensions: Technology, Organisation, External Environment, and Human Resources, which are derived from established e-readiness models. This study also proposed the measurement indicators that have been adapted to the characteristics of micro enterprises. Using quantitative data from 641 food and beverage (F&B) micro-enterprises in Batu City, Indonesia, exploratory factor analysis (EFA) was applied to evaluate construct validity. Despite the elimination of five indicators due to insufficient communality value, the overall model structure remained statistically valid. Subsequently, factor analysis was succeeded by the calculation of E-Readiness index using weighted aggregation and normalisation methods.  The resulting E-Readiness Index for Batu City was 46.47, with 57.10% of enterprises classified as “Not Ready,” primarily due to technological and infrastructural limitations.  The proposed model in this study efficiently assesses e-readiness at the micro-enterprise level and is adaptable for application in different regions or business sectors.  This model also provides valuable insights for policymakers in formulating targeted digital support initiatives.  Future research may consider expanding the scope of indicators and validating the model using confirmatory analysis.
