Abstract

Training is a form of Community Service or Pengabdian Kepada Masyarakat (PKM) carried out by lecturers. The target of the training is students with weight conversion material. The stages carried out are taking care of the PKM implementation permit, preparing the place as well as the tools and materials needed in the training, and implementing PKM. Weight conversion is interpreted as the weight of units between units having the same value. Weight conversion must be mastered by students as prospective teachers so that media creation training is needed. The training was held in March 2025 at Building 1.3, Musamus University. The results of the weight conversion training were that students were able to use weight conversion media and explain the conversion method in detail. The benefits obtained were that lecturers could share knowledge and experience in developing weight conversion media; for students, the benefits obtained were being able to make weight conversion media, becoming one of the media used when teaching, increasing creativity, and better communication skills.

Abstract

IPLT Keputih, the only fecal sludge treatment plant in Surabaya City, plays a critical role in the city's sanitation infrastructure. Its operation is critical to manage the fecal sludge generated by Surabaya residents, ensuring that the effluent is effectively treated before being safely discharged to the environment. According to previous studies, IPLT Keputih still has significant untapped potential, especially in the Solid Separation Chamber (SSC) and Grease Trap (GT) units, which have idle capacity that can be optimized to improve overall efficiency. The study involved primary and secondary data collection. Primary data was collected through comprehensive field observations and measurements, while secondary data was obtained from relevant agencies. Data analysis showed that IPLT Keputih currently treats an average of 97.71 m3 of septage per day. However, the facility has an idle capacity of 139.89 m3/day, which indicates a great opportunity to improve utilization. The calculation of the existing idle capacity was conducted based on the maximum discharge of sludge entering the IPLT Keputih in 2022. Several scenarios were developed to fully utilize the idle capacity of the SSC and GT units. The scenarios include the optimization of the SSC unit through improved desludging services, the optimization of the SSC and GT through improved non-fecal sludge management services for restaurants, as well as the implementation of a blended approach to improve the overall service of IPLT Keputih.

Abstract

Evaluasi unit operasi dan unir proses IPLT Keputih perlu dilakukan, guna menunjang tingkat pelayanan IPLT Keputih. Pengujian karakteristik lumpur yang masuk ke IPLT dilakukan dengan melakukan pengujian di laboratorium terkait parameter pH, BOD, COD, TSS, TVS, TFS, N, P, minyak, lemak serta uji SVI. Sampel yang diambil dari beberapa tempat, yaitu berasal dari non tinja seperti Sentra Wisata Kuliner, Rusunawa, Sentra Pasar Ikan, Fasilitas Kesehatan, Mall dan Restoran. Sedangkan untuk lumpur tinja diambil dari masing-masing unit pengolahan di IPLT Keputih. Berdasarkan karakteristik masing-masing beban pencemar, yaitu berasal lumpur non tinja dan tinja mengindikasikan beban yang cukup besar. Beban lumpur sendiri yang didapatkan dari Rusunawa mengindikasikan bahwa lumpur masih tergolong segar, belum ada degradasi yang terjadi. Hasil penelitian menunjukkan bahwa karakteristik lumpur tinja dari masing-masing unit pengolahan IPLT Keputih masih melebihi baku mutu yang berlaku. Besarnya beban pencemar yang masuk ke IPLT Keputih yang bukan hanya dari lumpur tinja, namun juga lumpur non tinja mengakibatkan beban pengolahan yang tidak sesuai idle capacity unit pengolahan di IPLT Keputih.

Abstract

This study aims to measure the effectiveness of reading e-books based on a contextual approach to the environmental care attitude of fourth grade elementary school students. This study is a quantitative study. The design of this study is a one group pretest-posttest design. Thus, it can be known more accurately, because it can be compared with being held before being treated. This study was conducted in SD Advent, SD YPK Kuprik and SD YPPK St. Fransiskus Xaverius 2 Merauke. Data collection techniques include tests, observations and documentation. The tests conducted include pretests and posttests. Quantitative data are pretest, posttest and N-gain scores, to determine how effective the application of local wisdom-based teaching materials is by looking at N-gain. The results of the study also showed that the pretest results of students' environmental awareness attitudes without using contextual approach-based reading teaching materials obtained a percentage of 47.25% with a category that was starting to be seen. The posttest results showed an increase in students' environmental awareness attitudes. Students' environmental awareness attitudes at the time of the posttest obtained a percentage of 82.42% with a category that had become a culture.

Abstract

This study aims to analyze the effect of profitability, leverage, liquidity, and firm size on tax aggressiveness in transportation and logistics companies listed on the Indonesia Stock Exchange (IDX) during the 2016–2023 period. This research uses a quantitative approach with a descriptive method. The data used are secondary data obtained from financial statements and annual reports. The data analysis technique employed is multiple linear regression using SPSS version 27.0. The results show that partially, profitability, leverage, and liquidity have a significant effect on tax aggressiveness, while firm size has no significant effect. Simultaneously, all independent variables significantly influence tax aggressiveness. The Adjusted R Square value of 0.347 indicates that the independent variables explain 34.7% of tax aggressiveness, while the remaining 65.3% is influenced by other variables outside the research mod

Abstract

Stakeholder value creation has become an essential concept in evaluating corporate sustainability and performance. However, discrepancies remain in measuring stakeholder value, particularly between traditional aggregation methods and more advanced weighting techniques. This study aims to compare stakeholder value creation measurement using the entropy weighting method (Xu et al., 2023) and the summation approach (Signori et al., 2021). The study employs a quantitative approach with paired sample t-test analysis to examine the differences between the two measurement methods. The results show a significant difference (p-value < 0.05) between the two approaches, indicating that the entropy method provides a more accurate and consistent representation of stakeholder value distribution. The entropy method demonstrates lower standard deviation, reflecting better data homogeneity and precision. These findings suggest that entropy-based measurement is more appropriate for capturing stakeholder value creation compared to the traditional summation method.

Abstract

Number bond is defined as a number bond meaning the separation of numbers into smaller values. There are similarities in the number bond principle with the calculations used by the Marind Tribe, Merauke, South Papua which is the background of the research. The purpose of the research is to develop a number bond book with an ethnomathematics approach with the intention of making mathematics easy to understand for students without eliminating the cultural elements and mathematical knowledge that students bring to school. The research uses the research and development (RnD) method through the planning and design stages. The results of the research show that the draft book consists of 3 chapters including chapter 1 containing the meaning, benefits, and how to teach number bond; chapter 2 describes ethnomathematics, the relationship between mathematics and culture, and the benefits obtained when studying ethnomathematics; and chapter 3 discusses the Marind Tribe, the Marind language, and Number bond in the Marind language.
