Authors: Abdul Norafnan  , Muhammad Ansari  , Slamet Riyadi
Published: November 2024

This article aims to describe the implementation of the Madrasah Education Section's Educator and Education Personnel Management Information System (SIMPATIKA) at the Palangka Raya City Office of the Ministry of Religious Affairs. The main focus in this research includes: implementation, effectiveness of use, and inhibiting factors of SIMPATIKA implementation. This research was conducted qualitatively with data collection through in-depth interviews, observation, and documentation. The results showed that: 1) The implementation of SIMPATIKA has been carried out by the Madrasah Education Section at the Palangka Raya City Ministry of Religious Affairs Office, which is managed by SIMPATIKA Special operators.2) The effectiveness of using SIMPATIKA as a madrasah data management system has not been fully realized.3) The inhibiting factors of SIMPATIKA implementation are mainly caused by the ignorance of some teachers in accessing the management information system for educators and education personnel (PTK). This has led to the delegation of SIMPATIKA account management to madrasah operators, whereas the account should be managed individually by each educator. The proposed solution is to hold technical guidance on the SIMPATIKA management information system, and provide an understanding of the rights and responsibilities in using individual SIMPATIKA accounts..

Authors: Elias James
Published: November 2024

Employees are the key players in successfully implementing the Financial Management Information Systems (FMIS) in public institutions. Therefore, it is important to understand and address the attitudes of employees towards behavioural intentions to use these systems. However, the empirical evidence specifically targeting FMIS implementation in public institutions is limited. This study determined the influence of employees' attitudes towards implementing FMIS in public institutions. The study adopted a quantitative research approach and the Decomposed Theory of Planned Behaviour (DTPB) in which a structured questionnaire was used to collect primary data. The study applied data analysis through SPSS to test Pearson Chi-Square, One-Way ANOVA and Ordinal Regression Analysis. The study found that attitudes influence the implementation of FMIS in public institutions. The findings suggest that public institutions have to strategise how to change the attitudes of employees to adapt to the use of information systems. The institutions should work towards complete participation of employees in the requirements of system users, adequate communication during implementation, hands-on training, and full support from developers of such systems. Also, the government must ensure that all the employees who are the principal users of these systems know the benefits of these accounting systems in day-to-day operations.

This article seeks to offer a descriptive analysis of the interventions of the Cabildo and other authorities in Buenos Aires, around the shortage of flour. We understand the latter as fundamental, due to their direct relationship with agricultural production and with the preparation and consumption of bread. In order to comply with what has been stated, we based ourselves fundamentally on the analysis of proceedings and other official records on the treatment of the lack of grains and their derivates. To identify similarities and differences at the regional level, we include examples from other towns and cities. The period studied is crossed by the demographic and economic growth of the city and its countryside, the greater demand of food, political and institutional reforms. We start from the hypothesis that the shortage was associated with bad crops, commercial excesses, speculation and fraud by bakers and millers, who concentrated a much of the supply.

Authors: Hannisa Kautsarani Hamidah  , Agus Khumaidi  , Ii Munadhif  , Ryan Yudha Adhitya
Published: November 2024

The apple cider vinegar fermentation process requires careful monitoring and control of variables such as pH, alcohol content, and amount of acetic acid.  This research adopts Fuzzy Logic Control by utilizing the MQTT communication protocol, pH, alcohol and water pump sensors, as well as solenoid valves and DC motors as actuators.  This Internet of Things (IoT) based solution provides real-time monitoring information on the fermentation process.  The results showed that the test system succeeded in maintaining a stable pH of around 3.9-4.0 during the initial stages of fermentation, while industrial data showed greater variations.  Alcohol content increased consistently in the test system, in contrast to the spike on day 7 in industry data.  At the formulation stage, the pH dropped to 3.68 in the test system, while the industry maintained 3.70.  At medium and slow mixing stages, the test system showed a significant decrease in pH and a consistent increase in alcohol.  At the harvest stage, the pH was lower in the test system compared to industrial, with slightly higher alcohol content.  Test results show that the implementation of this system can reduce the fermentation process time by up to 2 days faster compared to conventional methods.  This conclusion shows that IoT-based systems are able to provide better control and monitoring than conventional systems, so they have great potential for wider adoption in the apple vinegar fermentation industry to increase production effectiveness.

Authors: Andi Muhammad Rezky Putra Ardian  , Adnan Adnan  , Abd. Muis Baharuddin
Published: November 2024

Porous concrete is commonly used in road linings with minimal traffic, parking areas, pedestrian paths, and parks. The strength of porous concrete depends on the size of the aggregate and the correct composition of water and cement. The objective of the study was to analyse the effect of cement water factor in uniformly graded porous concrete on compressive strength and permeability in uniformly graded porous concrete on permeability values. The relationship between the compressive strength of concrete tends to decrease as the value of cement water factor increases. The water-cement factor strongly influences the permeability value. The greater the value of cement water factor, the smaller the permeability of uniformly graded porous concrete, this is due to the deposition of cement water at the base of the slab. The use of super plasticizer (SP) in porous concrete accelerates the pavement process, but does not improve permeability. cement water factor 0.35 with a 28-day treatment period obtained a Slump test value of 178 mm, cement water factor 0.5 of 192 mm, cement water factor 0.6 with a 28-day treatment period obtained a Slump test value of 196 mm. while porous concrete with a cement water factor of 0.35 has an average compressive strength of 6.13 Mpa, while a cement water factor of 0.50 has an average compressive strength of 5.47 Mpa, and a cement water factor of 0.60 has an average compressive strength of 5.00 Mpa.
