Abstract

Indonesia adalah negeri jamrud di khatulistiwa yang kaya raya dengan sumber daya alam, namun demikian kekayaan alam tidak berbanding lurus dengan kesejahteraan rakyat. Letak kesalahan pengelolaan negeri ini tidak ada yang dapat memberikan penjelasan dengan memuaskan. Tulisan ini hanya sekedar pemikiran untuk memperkaya panduan perilaku Pengelola dan Rakyat Indonesia dalam berekonomi. Negara Indonesia ini telah dihuni oleh Pengelola dan Rakyat yang banyak belajar tentang ilmu pengetahuan yang rasionalis namun kurang memperhatikan rasa. Ilmu pengetahuan yang dilahirkan dari jaman renaissance lebih sekuler. Sekulerisme ilmu pengetahuan sesungguhnya menjadikan manusia berkepribadiaan terbelah (split personality), yakni manusia yang terpisah antara akal dan jiwanya; antara kepintaran dan kesalehan; antara ilmu dan perilaku; antara badan dan ruh. Manusia terdiri dari jiwa atau rasa dan badan. Pemisahan jiwa atau rasa dan badan menjadikan pandangan manusia tidak sebagai manusia yang utuh. Sekularisasi ilmu pengetahuan sebenarnya tidak sesuai dengan cita-cita luhur pendiri Bangsa Indonesia yang menghendaki pembangunan jiwa dan raga. Ilmu barat modern menjadikan alam semakin cepat mengalami krisis multi dimensi. Tulisan ini mengajak kita semua untuk kembali menyatukan antara Ilmu Ekonomi dan Agama, karena Agama adalah sumber ilmu.

Abstract

Tujuan PKMM ini adalah memberikan pelatihan pengolahan tanaman singkong menjadi aneka makanan olahan yang bernilai ekonomi tinggi. Target kegiatan PKMM ini adalah memberikan pelatihan kepada ibu rumah tangga di Dusun Mrico Desa Lebak, Grobogan. Setelah diberikan pelatihan maka selanjutnya mereka akan melakukan praktek secara terbimbing dan dilakukan pendampingan usaha. Pelatihan dilakukan secara berkelompok dengan pendekatan andragogi. Materi pelatihan disajikan dengan lebih banyak praktek dari teori, dengan rasio perbandingan 30 % teori dan 70 % praktek. Pelaksanaan PKMM telah memberikan pengetahuan kepada peserta pelatihan tentang diversifikasi olahan singkong, pengemasan dan pelabelan, sertifikasi cara produksi pangan yang baik, tata letak produksi, kewirausahaan, perhitungan harga jual dan titik impas, serta materi praktek pengembangan produk yang meliputi pembuatan keripik singkong aneka rasa. Pengabdian berjalan dengan baik karena adanya koordinasi yang baik antara ketua tim PKMM dengan anggota tim PKMM dan juga komunikasi yang baik dengan pihak eksternal mitra untuk menjalin kerja sama yang berkelanjutan. Namun demikian, masih ada satu kendala yaitu mindset warga yang masih sulit berubah menjadi wirausaha. Oleh karena, untuk merubah mindset tersebut tim PKMM akan fokus di lokasi pelatihan dan memberikan pendampingan dalam pemasaran produk keripik singkong yang dihasilkan.

Abstract

Fraud is a problem that occurs in various organizations, including educational institutions. This condition is very ironic, educational institutions as institutions are required to teach anti-fraud education, but in fact, the educational institutions themselves are still fraudulent. This study aimed to explain the factors that can influence the principal, treasurer, and school committee to abuse school aid funds. The research sample was 145 principals, treasurers, and school committees for the elementary, junior high, and senior high school levels selected by convenience sampling method. All variables were measured using five Likert scales and analyzed with the multiple regression method. Instrument validity test using Pearson product-moment. This study shows that we found that pressure, internal control, integrity, and religiosity influence fraud. High financial pressures stemming from greed, a luxurious lifestyle, debt, integrity, low systems of control, and religiosity can increase fraud. These results reinforce the importance of schools or education-related regulatory agencies to be able to take policies to form a school environment that encourages honesty, limits teachers to hedonism, has a fair compensation system, and encourages teachers to practice worship, which needs to be done to avoid financial fraud from abuse of school aid funds.

Abstract

This study aimed to see how financial distress, conflicts of interest, and litigation risk affected accounting conservatism when an audit committee was present as a moderating variable. The population was manufacturing companies indexed at the Indonesia Stock Exchange (IDX) in 2019-2021. The tool employed descriptive and moderation regression analysis. The findings of this research showed that financial distress, conflicts of interest, and litigation risk had a significant positive effect on accounting conservatism. However, the audit committee could not moderate the impact of financial distress, conflict of interest, and litigation risk on accounting conservatism. Financial distress had a significant positive effect on accounting conservatism. Litigation risk was one of the negative impacts of agency problems in a company. These results supported the agency theory, which explains that lawsuits or litigation risks can occur due to differences in interests between management and investors, creditors, or the government. This research contributes to accounting standard policymaking, particularly in applying the conservatism principle. Based on the occurrences and findings of past investigations, which are still inconsistent, the originality of this study was to see how financial distress, conflicts of interest, and litigation risk affected accounting conservatism by including the audit committee variable as a moderating variable.

Abstract

Weather and climate play an important role in everyday life, influencing various aspects of society and the environment. The city of Yogyakarta as a cultural center cannot be separated from the impacts of climate change, including rainfall patterns which can have significant effectiveness on daily activities, agriculture and infrastructure. This research uses a fuzzy logic methodology approach with the Mamdani method to predict rainfall. Fuzzy logic has proven to be effective in cold situations and is able to overcome the challenges of missing or incomplete data. The data used in this research was obtained from Bappeda DIY. The implementation for predicting rainfall levels uses Matlab by utilizing the provided Fuzzy Logic Matlab Toolbox. Based on research conducted using a fuzzy logic test to calculate all research accuracy data, an average error value in RMSE was obtained of 39.88%. These results indicate that there is significant error in these predictions, indicating that the fuzzy logic control model is not completely accurate. Therefore, it is necessary to review the data used in this prediction to ensure its accuracy.

Abstract

Global environmental concerns requiring excellent air quality have prompted the development of a variety of eco-friendly energy sources. Hydrogen gas is an environmentally friendly option that may be created using an electrolysis device that converts water into hydrogen (H2) and oxygen (O2). In this study, a dry cell electrolyzer with a polyvinyl alcohol (PVA) membrane was used as a separator between two stainless steel 316 electrodes to generate a high hydrogen yield. The hydrogen gas production from the dry cell electrolyzer was determined using gas chromatography. The results showed that using a KOH electrolyte and a PVA membrane considerably enhanced the hydrogen gas composition. Hydrogen gas compositions after electrolysis using a dry cell electrolyzer without a PVA membrane and KOH electrolyte concentrations of 0 M, 0.04 M, 0.07 M, and 0.11 M being 13.70%, 25.10%, 32.50%, and 15.60%, respectively. With a PVA membrane, the hydrogen compositions were 71.50%, 89.10%, 80.50%, and 84.60%, respectively. The results of these experiments show that the most hydrogen gas was produced utilizing a dry cell electrolyzer with a PVA membrane and a 0.04 M KOH electrolyte concentration. When a PVA membrane and a KOH electrolyte are utilized in electrolysis, the hydrogen gas composition improves significantly compared to when either is utilized.

Abstract

Indonesian aquaculture cultivation production of catfish has been growing faster than other fish. It is a potential source of fish oil and contains polyunsaturated fatty acids that have health benefits. The objective of this study was to perform physicochemical characterization and fatty acid profile of catfish oil. This study used fish oil extracted from the head and the flesh of catfish using dry rendering with a mechanic press. The result showed that catfish flesh oil (CFO) and catfish head oil (CHO) were significantly different parameters (p<0.05) in terms of physicochemical characteristics including acid value, peroxide value, iodine value, and saponification value. The best characteristics are catfish flesh oil than catfish head oil for acid value, peroxide value, iodine value, and saponification value following the number is 2.17 mg KOH/g, 5.15 meqO2/kg, 76.13 I2/100 g, 175.86 mg KOH/g. The predominant fatty acids were oleic, palmitic, and linoleic acids. These catfish oils are found suitable for consumption for beneficial health effects.

Abstract

Fish is a product with high nutritional content, and the development of fish oil has made it easier for consumers to consume. High-quality fish oil can be a target for adulteration, such as with vegetable oils like palm oil. FTIR spectroscopy was developed for the authentication of bawal fish oil (BFO) from palm oil (PO). Bawal fish oil and palm oil were prepared in binary mixtures with concentrations from 0-100%, resulting in 21 mixtures. The oil was directly measured by attenuated total reflectance (ATR) spectral measurement in the mid-infrared region (4000-600 cm-1). The results were combined with linear discriminant analysis (LDA) and multivariate calibration, such as PLSR or PCR. The results showed that LDA could make clear discrimination between bawal fish oil, palm oil, and their mixtures without any misclassification observed. Multivariate calibration with PLSR using the first derivative spectrum provided the best model for the relationship between actual and predicted FTIR values. At this conditions, the R2 values for the calibration and validation models obtained were 0.9966 and 0.9969, with RMSEC and RMSEP values of 0.0249 and 0.0248, respectively. Therefore, FTIR spectroscopy combined with LDA and PLSR is an effective method for authenticating bawal fish oil from palm oil.
