Abstract

This research designs and builds a device capable of sorting and counting the number of items automatically by utilizing the working principle of a laser sensor. The system is controlled by an ATmega8535 microcontroller, enabling it to operate without manual intervention. The main components of the system include an item detection sensor, a control unit, a conveyor, and a power supply. The detection process is carried out using an ATmega8535 microcontroller, laser, photodiode, LCD, and computer display. System testing includes testing the sensor circuit, servo motor, and automatic sorting and counting functions. When the laser sensor detects an object, the data is sent to the microcontroller and then displayed on the LCD screen and computer. The system is also equipped with an automatic separator bar to separate acceptable and unacceptable items using a DC servo motor. The system's detection accuracy reaches 95–100% with an error margin of 0–5%.

Abstract

Multiple linear regression is one commonly used method in predicting, knowing the influence of several variables at once, predicting the value of dependent variables, and as a control variable. In its application, it is very widely used in the economic field. This study examines the influence of various factors on food and non-food consumption in North Sumatra from 2011-2022. Dependent variables include economic growth, inflation, human development index, unemployment rate, and poor population. The model equation using multiple linear regression is Ŷ = -6.268 + 0.000X1 - 0.004X2 + 0.105X3 + 0.028X4 - 0.036X5 then on the simultaneous test (F-test) shows F-count 167.91 > F-table (4.39). While the value (R2) was 0.993, indicating that independent variables affected 99.3% of the variation in consumption, with 0.7% explained by other factors. The double correlation between the free and bound variables was 99.6%.

Abstract

The gross up method is one of the approaches in calculating Article 21 Income Tax (PPh) used by employers. In this method, the taxes that are borne by the employee are borne by the company through the provision of tax allowances, where the amount of the allowance is equivalent to the amount of Income Tax Article 21 owed by each employee. This study is to determine the application of tax planning using the gross up method. This type of research is qualitative descriptive research. Data were obtained using documentation and interview methods. The results of the study show that the gross up method can increase the amount of gross income incurred by the company quite largely, namely Rp. 1,093,449,391, but tax allowances worth Rp. 20,011,136 provided by the company can be charged as deductible expenses, so that there is no need to make a positive fiscal correction and there are savings for the company in corporate income tax which is Rp. 4,402,450.

Abstract

Investment decision-making, such as buying or maintaining fixed assets, requires relevant and precise information. Differential accounting information is one of the tools in assessing alternative decisions rationally. This study aims to analyze the application of differential accounting information in making decisions to buy new heavy equipment machines or maintain old ones at PT. The Eternal Glory of Manado. The method used is descriptive qualitative, with primary and secondary data through interviews and observations. The results of the study show that differential accounting information helps companies compare the relevant costs of the two alternatives. In the short term, maintaining old machines is more profitable, but in the long term the purchase of new machines provides higher efficiency and productivity. Thus, differential accounting information is important in supporting more informed investment decisions.

A qualitative method with a phenomenological design was used to explore employees’ subjective experiences of organizational communication practices. Data collection techniques include in-depth interviews, participatory observation, and document analysis, with thematic and interpretive analysis employed. The findings reveal that communication in the Bureau occurs multidirectionally, is adaptive to digital channels, includes inclusive content, and adopts a flexible communication style.

Abstract

This study aims to analyze the implementation of the School Procurement Information System (SIPLah) policy at SMAN Pesanggaran, Banyuwangi Regency. The main problems lie in the effectiveness and efficiency of SIPLah implementation, considering the limitations in resources, institutional capacity, and the lack of technical training. This study adopts a qualitative approach with a case study design, using data collection techniques such as in-depth interviews, observations, and documentation. The results show that, normatively, SIPLah implementation complies with existing regulations. However, it remains suboptimal due to technical and administrative challenges, as well as the lack of institutional support. Strengthening technical capacity, improving supervision, and providing contextual policy support are necessary to ensure effective and sustainable implementation.

Abstract

The Indonesian Air Force Academy (AAU) is committed to improving the quality of education by developing an Academic Information System (Siakad). Siakad plays a crucial role in enhancing academic administration efficiency, facilitating the management of educational data, and supporting institutional accreditation achievements. This system enables the management of data related to cadets, lecturers, courses, and community service activities. With Siakad, academic administrative processes that were previously manual can now be handled more effectively and efficiently, reducing human errors and ensuring transparency. The use of Siakad at AAU has great potential to improve efficiency, transparency, and accuracy in education management. To achieve this, AAU must ensure technological infrastructure improvements, intensive training for lecturers and administrators, and better integration of various systems supporting academic activities.
