Abstract

The commercial synthesis of fatty acid esters of glycerol is important because it can be used for other derivative production varieties. This research aims to construct the quality monitoring system for esterification condition faster and more efficient for the production of esterification glycerol. The monitoring systems were based on the measurement parameters from two inputs LED mid IR 3,4 and 5,5 μm sensors that using the data acquisition with computer database via USB 2.0 using Arduino Leonardo microcontroller and classifying the esterification quality condition using the classification method K-Nearest Neighborhood (KNN) The purpose of KNN method is to classify the variations of parameter inputs from the LED mid IR sensors in quality monitoring. In this research the condition of esterification was divided into three conditions: not good, fair,good., these classification was trained and tested in Orange Software for data mining using receiver operating characteristic (ROC) curve that is a graphical plot that illustrates the excellent performance of a classifier system for esterification condition with AUC . In application for quality monitoring, the influence of various parameters such as temperature set in the reactor has relation to the quality of product. By using this system, we obtained the optimum process conditions is 200oC and time needed for the process was 200 minutes.

Abstract

Taekwondo merupakan salah satu cabang olahraga bela diri yang mengandalkan kecepatan dan ketepatan tendangan. Dalam latihan, diperlukan alat bantu yang dapat mengukur kekuatan serta kecepatan tendangan secara objektif. Penelitian ini bertujuan untuk merancang dan membangun alat latihan teknik tendangan taekwondo berbasis Arduino Mega yang mampu memberikan target tendangan secara otomatis dan menilai respons atlet. Sistem ini menggunakan motor DC sebagai aktuator, sensor tekanan FSR402 untuk mendeteksi kekuatan tendangan, serta LED sebagai indikator kecepatan. Metode penelitian mencakup perancangan perangkat keras dan lunak, pengujian sensor tekanan, serta evaluasi sistem secara keseluruhan. Hasil pengujian menunjukkan bahwa alat dapat beroperasi dengan baik dalam memberikan target tendangan secara acak maupun terstruktur, serta mampu menampilkan umpan balik kecepatan tendangan melalui sistem LED. Keberhasilan alat ini diharapkan dapat meningkatkan efektivitas latihan atlet taekwondo dalam meningkatkan ketepatan dan kecepatan tendangan, sekaligus memberikan metode evaluasi yang lebih objektif bagi pelatih.

Abstract

The purpose of this research is to obtain empirical evidence supporting the hypothesis that sustainability reports can reduce shareholders' negative reactions to tax avoidance. The selected research sample consists of non-financial companies listed on the Indonesia Stock Exchange over a period of five years (2018-2022). The research data were tested using panel regression methods. The results of the test on 1.690 observation data indicate that only 40% of the samples engage in sustainability reporting. This suggests that a considerable number of publicly listed companies in Indonesia do not engage in sustainability reporting. The results of the analysis indicate that tax avoidance does not have a significant impact on the company's value. Sustainability reporting as a moderating variable has a positive effect on the relationship between tax avoidance and the company's value. Several control variables have a significant impact on firm value, namely leverage, profitability, and plant assets. This study contributes to the analysis of the impact of tax avoidance on the value of companies in Indonesia, moderated by sustainability reporting.

Abstract

This study aims to identify and strengthen the strategic role of women in the development of the creative economy through a community-based participatory empowerment approach. Located in Jagakarsa District, Jakarta, this Community Service activity employed a qualitative descriptive method combined with a participatory approach. Data collection techniques included observation, in-depth interviews, focus group discussions (FGDs), and pre-posttest questionnaires with 35 female micro and small business owners in the culinary and craft sectors. The results showed significant improvements in digital literacy, managerial skills, and product branding skills among participants. Furthermore, the formation of a network of women entrepreneurs strengthened local collaboration and leadership. However, structural barriers such as limited access to financing and the burden of multiple roles hinder business sustainability. These findings confirm that integrating technology-based training, strengthening social networks, and a participatory empowerment approach is an effective strategy for building the capacity of women as key actors in the local creative economy. This research provides a conceptual contribution to gender-based inclusive economic development and a contextual and sustainable empowerment model.

Abstract

This project focuses on developing a comprehensive Tax Standard Operating Procedure (SOP) for PT Momentum Sample Indonesia as a response to the company’s lack of formalized tax administration guidelines. Previously, tax-related tasks were performed based on informal habits, which led to inconsistent practices, unclear responsibilities, calculation errors, and increased exposure to administrative sanctions. Through a qualitative methodology involving direct observation, interviews with accounting/tax personnel, and examination of relevant documents, the program identified operational problems and designed standardized procedures for the completion of both periodic (SPT Masa) and annual (SPT Tahunan) tax obligations. The finalized SOP compiles step-by-step procedural narratives, workflow flowcharts, tax rate references, calculation templates, and document archiving standards to improve accuracy, efficiency, and regulatory compliance. Its early implementation yielded notable results, including clearer process mapping, improved accuracy in tax computations, strengthened documentation systems, and the identification of previously overlooked 2023 tax outstanding through structured reconciliation with the Coretax DJP database. These findings show that the SOP functions not only as an operational guideline but also as an effective mechanism for detecting legacy compliance issues. Future recommendations include integrating automated tax features via accounting or ERP systems, conducting periodic internal compliance audits, routinely updating the SOP in line with regulatory developments, enhancing staff capability in digital tax platforms, and reinforcing the company’s digital archiving infrastructure.
