Abstract

Micro, small, and medium enterprises (MSMEs) is a form of business which is stipulated in Law No.20 of 2008 where the amount is very dominant in Indonesia. One of the obstacles in developing MSMEs is the limited access to funds. One of which is caused by the absence of financial statements based on the Accounting Standards for Entities Without Public Accountability (SAK-ETAP). MSMEs also experienced a shortage of human resources, especially in technology and accounting. To overcome this and to lead a good corporate governance, we need an accounting information system for MSMEs. This research resulted the accounting information system for MSMEs based on SAK-ETAP and has a general nature so that it can be applied to business in service sector with minor adjustments. This research resulted the complete information system as well as the UML design. The study also attached the complete mapping of each type of transactions to the financial statements. By using this information system, the MSME’s especially in service sector could generate the financial statement, order, invoice, and other report automatically

Abstract

Gender equality is one important item from the United Nation’s Sustainable Development Goals (SDGs). It makes a gender gap in companies’ top management becomes valuable to be studied because people still have a stereotype that leadership is a masculine job. This research will test the effect of performance, payment, bankruptcy risk, and earnings management. Data is taken from Indonesian public companies in 2016 using means different statistical test. The result shows that 30.9% or minority corporation have a female director. Hence, while women were given the opportunity to lead, the companies will have better performance and compensation than their male only board of director counterparts. It is proof that gender stereotypes happen in Indonesian Public Companies Leadership.

Abstract

This study aims to compare the effectiveness of machine learning models and economic models in predicting corporate bankruptcy, with a focus on addressing the issue of data imbalance. In this context, the number of companies experiencing financial difficulties is significantly smaller than that of healthy companies, which can lead to bias in predictions. The method used is an experiment with various data handling techniques and involves several classification models, namely Decision Tree, Neural Network (NN), K-Nearest Neighbors (KNN), Case-Based Reasoning (CBR), Support Vector Machine (SVM), and Merton Structural Model, which are tested on several data scenarios with resampling techniques, including Random Oversampling (ROS), Random Undersampling (RUS), and a combination of both. The evaluation results show that the Decision Tree, excluding ROA variables, and the Neural Network provide the best performance, with the Decision Tree achieving 86% accuracy and an AUC of 77.75, and the Neural Network achieving 86.76% accuracy and an AUC of 90.5. Other models, such as KNN and SVM, exhibit lower performance, achieving around 80% accuracy and a lower AUC. Based on these results, Decision Tree without ROA and Neural Networks are the best choices for predicting corporate bankruptcy. This study also demonstrates that financial models, such as the Merton Structural Model, are not significantly affected by data imbalance. The ultimate goal of this study is to provide recommendations for more reliable prediction models that enable financial institutions, investors, and companies to make more informed strategic decisions, as well as reduce financial risks through the early detection of companies at risk of failure.

Abstract

Mangkalaya Village in Sukabumi Regency faces the problem of organic waste management that has not been optimally handled. Approximately 115.10 m³ of waste per month with a composition of 56% organic waste, only 36% is transported to the landfill, while the rest is burned or dumped into the environment, causing pollution, health risks, and greenhouse gas emissions. This community service activity aims to implement Microbial Electrolysis Biodigester (MEB) Technology as a solution for processing organic waste into biogas and liquid organic fertilizer, while empowering the community to become an independent village in processing waste. The approach used includes socialization, technical and business management training, construction and commissioning of a community-scale MEB reactor unit, operational assistance, and technology and socio-economic evaluation. Data were collected through field observations, interviews, reactor operational records, and documentation of the activities of ABEL Porridge and Wet Cake MSME partners. The program successfully installed one MEB reactor unit with a design capacity of 1,000 L of organic waste, to process household waste and remaining MSME raw materials. Initial operational tests showed that the reactor was able to produce biogas that began to be used on a household scale and liquid organic fertilizer that was tested on residents' land. Waste incineration practices have decreased, while organic waste sorting has increased in partner households. However, through intensive mentoring and strengthening the role of partners, most of the first-year output indicators, including technology installation, increased production capacity, the formation of management groups, and publications, have been achieved. The implementation of MEB in Mangkalaya Village has proven technically and socially feasible as the first step for an independent village to manage waste. The next phase focuses on optimizing operations, strengthening the biogas and fertilizer business model, and replication to other villages.ABSTRAKDesa Mangkalaya di Kabupaten Sukabumi menghadapi persoalan pengelolaan sampah organik yang belum tertangani optimal. Sekitar 115,10 m³ sampah per bulan dengan komposisi 56% sampah organik hanya 36% yang terangkut ke TPA, sedangkan sisanya dibakar atau dibuang ke lingkungan sehingga menimbulkan pencemaran, risiko kesehatan, dan emisi gas rumah kaca. Kegiatan pengabdian ini bertujuan menerapkan Teknologi Mikroba Elektrolisis Biodigester (MEB) sebagai solusi pengolahan sampah organik menjadi biogas dan pupuk organik cair, sekaligus memberdayakan masyarakat menuju desa mandiri mengolah sampah. Pendekatan yang digunakan meliputi sosialisasi, pelatihan teknis dan manajemen usaha, pembangunan dan komisioning satu unit reaktor MEB skala komunitas, pendampingan operasional, serta evaluasi teknologi dan sosial-ekonomi. Data dikumpulkan melalui observasi lapangan, wawancara, pencatatan operasional reaktor, dan dokumentasi aktivitas mitra UMKM Bubur dan Kue Basah ABEL. Program berhasil memasang satu unit reaktor MEB berkapasitas desain 1.000 L sampah organik, untuk mengolah sampah rumah tangga dan sisa bahan baku UMKM. Uji operasi awal menunjukkan reaktor mampu menghasilkan biogas yang mulai dimanfaatkan pada skala rumah tangga serta pupuk organik cair yang diuji pada lahan warga. Praktik pembakaran sampah berkurang, sementara pemilahan sampah organik di rumah tangga mitra mulai meningkat. Namun, melalui pendampingan intensif dan penguatan peran mitra, sebagian besar indikator luaran tahun pertama yaitu instalasi teknologi, peningkatan kapasitas produksi, terbentuknya kelompok pengelola, serta publikasi dapat dicapai. Penerapan MEB di Desa Mangkalaya terbukti layak secara teknis dan sosial sebagai langkah awal desa mandiri mengolah sampah. Tahapan berikutnya difokuskan pada optimasi operasi, penguatan model bisnis biogas dan pupuk, serta replikasi ke desa lain.
