Abstract

relatively shorter adult phase than the larval stage. The larval stage of this organism lives in piles of organic matter, including in piles of household waste. The ability of larvae to utilize organic matter in their environment is inseparable from the role of potential microbes that produce enzymes associated with their gut. This study aims to isolate, screen, and identify the potential bacteria in producing hydrolytic enzymes from gut of O. rhinoceros larvae. The third instar larvae were dissected aseptically to obtain gut bacterial isolates. The isolates were tested for their ability to produce amylase, cellulose, lipase, and protease using agar plate containing specific substrates. There were eight different isolates, and three of them had the ability to produce all four enzymes. The three isolates were identified as Bacillus. These results can be used as a reference for handling household organic waste.

Abstract

Artikel ini membahas konstruksi entity business melalui integrasi perspektif modern dan nilai-nilai keislaman. Dalam konteks modern, entity business difokuskan pada penciptaan nilai ekonomi, inovasi, dan keberlanjutan, namun sering mengabaikan aspek spiritual dan etika. Dengan menggunakan pendekatan holistik yang menggabungkan prinsip-prinsip syariah, artikel ini menegaskan pentingnya keselarasan antara tujuan duniawi dan ukhrawi. Temuan menunjukkan bahwa integrasi nilai-nilai Islam, seperti tauhid, maslahah, dan akhlak, memberikan kerangka kerja yang lebih berkelanjutan dan bermakna bagi pengelolaan entity business.

Abstract

Pertumbuhan penduduk perkotaan yang terus meningkat menimbulkan dampak spasial yang serius bagi kehidupan kota, terutama dengan meningkatnya kebutuhan akan tempat tinggal atau permukiman, yang berpotensi terjadinya ketidakseimbangan kemampuan lahan permukiman. Penelitian ini bertujuan untuk menganalisis spasial daya dukung lahan permukiman di Kota Sentani dengan mengukur besaran luas lahan permukiman dan data jumlah penduduk. Hasil penelitian menunjukkan bahwa luas lahan permukiman di Kota Sentani pada tahun 2023 mencapai 704.874,57 m², sementara jumlah penduduk sebanyak 73.927 jiwa. Nilai Daya Dukung Lahan Permukiman (DDPm) yang diperoleh sebesar 0,36 m²/kapita, yang menunjukkan bahwa daya dukung lahan di Kota Sentani tergolong rendah dan tidak mampu menampung kebutuhan penduduk dengan layak. Faktor utama yang memengaruhi kondisi ini adalah alih fungsi lahan yang tidak terkendali, distribusi infrastruktur yang tidak merata, serta keterbatasan lahan akibat kawasan konservasi Pegunungan Cycloop dan Danau Sentani. Hasil penelitian ini diharapkan dapat mendukung perencanaan tata ruang berbasis daya dukung lahan secara berkelanjutan dan mencegah dampak negatif pembangunan, seperti degradasi lingkungan dan risiko bencana. Dengan demikian, hasil penelitian ini diharapkan dapat menjadi dasar kebijakan dalam pengelolaan dan pengembangan wilayah Kota Sentani secara bijaksana dan berkelanjutan.

Abstract

Propolis, which is produced by Tetragonula sp., has the potential to treat a number of illnesses, including microbial infections, wounds, depression, and cancer. However, in order for propolis to be used as a raw material for traditional medicine, it must be standardized. The goal of this study was to standardize the values of specific and non-specific parameters. Propolis was extracted using the maceration method with 70% ethanol solvent until a thick extract was obtained, and the thick extract was tested for both specific and non-specific parameters. In terms of specific parameters, the obtained extract is a thick yellowish-brown liquid, has a characteristic sour propolis scent, and is sticky. Phytochemical screening also showed that the extract was positive for flavonoids, phenolics, alkaloids, saponins and tannins. Meanwhile, the nonspecific test obtained a drying shrinkage value of 35.059%, moisture content of 33.698%, specific gravity of 1.0082 g/ml, and total ash content of 1.26%. The results of the specific and nonspecific parameter tests have met the established extract requirements. Further quantitative identification of the activity of compounds in propolis is recommended for the development of traditional medicine.

Abstract

Pemahaman konsep matematika yang benar sejak sekolah dasar berperan penting dalam mengembangkan keterampilan berpikir logis dan pemecahan masalah, termasuk dalam aspek numerasi. Namun, Rapor Pendidikan Kota Makassar Tahun 2024 menunjukkan bahwa kemampuan numerasi peserta didik sekolah dasar masih berada pada kategori sedang dan mengalami penurunan dibandingkan tahun sebelumnya, yang mengindikasikan kesulitan dalam menguasai konsep dasar matematika. Penelitian ini bertujuan untuk menganalisis efektivitas kegiatan refleksi dalam pendekatan Teaching at the Right Level (TaRL) terhadap pemahaman konsep matematika dan keterlibatan peserta didik. Metode penelitian menggunakan Mixed Methods dengan desain Embedded Design, yaitu data kuantitatif dikumpulkan melalui eksperimen kuasi One-Group Pretest-Posttest, sementara data kualitatif diperoleh melalui observasi keterlibatan peserta didik. Hasil penelitian menunjukkan bahwa integrasi refleksi dalam pendekatan TaRL secara signifikan meningkatkan pemahaman konsep matematika, dengan peningkatan rata-rata skor dari 56,2 menjadi 74,8 (p = 0,0001), serta meningkatkan keterlibatan peserta didik dalam diskusi kelas, kerja kelompok, dan kemandirian dalam menyelesaikan soal. Dengan demikian, penerapan refleksi dalam pembelajaran berbasis TaRL dapat menjadi strategi yang efektif untuk meningkatkan pemahaman konsep matematika dan keterlibatan peserta didik di sekolah dasar.

Abstract

This qualitative study examines standard operating procedure (SOP) implementation for tugboat clearance operations at Jepara Port, analyzing service quality enhancement through comprehensive stakeholder engagement. Utilizing semi-structured interviews with 25 participants across five stakeholder categories, the research reveals significant operational improvements including a 35% reduction in clearance processing times and a 35.5% increase in stakeholder satisfaction scores. Findings demonstrate that standardized procedures enhance port operational efficiency while strengthening maritime vocational education integration. Beyond efficiency gains, the study highlights the role of SOPs in ensuring transparency, accountability, and consistency in port service delivery. Respondents emphasized that clear procedural guidelines reduce uncertainty, minimize conflicts between stakeholders, and establish a common framework for decision-making in dynamic operational contexts. Moreover, the integration of vocational education elements into procedural design strengthens workforce competencies, aligning training curricula with real-world port requirements and industry expectations. The study contributes both theoretically and practically by offering evidence-based frameworks that can be adopted by other Indonesian ports. It underscores the importance of combining procedural standardization with stakeholder collaboration to achieve sustainable improvements in maritime service quality. Overall, the findings establish replicable models for enhancing national port competitiveness and advancing maritime industry development through systematic procedural and operational innovation that ensures long-term sustainability and resilience.

Abstract

In the world of investment, investors must be able to identify investment opportunities that provide returns so that they can generate optimal levels of return with minimal risk. This study aims to analyze stock investment decisions using the Capital Asset Pricing Model (CAPM) using the LQ45 Index as a market proxy. This type of research is descriptive research with quantitative methods. The data source used is secondary data, namely monthly closing price data. The sampling in this study was determined using purposive sampling, out of 45 companies included in the LQ45 index, only 23 companies met the criteria and became a research sample. The data analysis method was used using the Capital Asset Pricing Model (CAPM) method to classify undervalued and overvalued stocks using Microsoft Excel 2016. The results of the calculation of the rate of return of individual shares (Ri) resulted in an average of 0.00506, with the largest return owned by ANTM shares and the lowest by INDF shares. The average systematic risk is worth more than 1, which is 1.25, so in general, the 23 shares of the companies used as research samples have high systematic risk and tend to be active in responding to market price changes. Based on the data analysis, there is a nonlinear relationship between systematic risk (β) and the expected rate of return on shares [E(Ri)]. Of the 23 company stocks that were the research sample, there were 12 company stocks that were included in the undervalued category, namely, ADRO, ANTM, BBCA, BBNI, BBRI, BBTN, BMRI, CPIN, EXCL, INCO, INKP, ITMG. Meanwhile, there are 11 company stocks that are in the overvalued category, namely, ASII, ICBP, INDF, INTP, KLBF, PGAS, PTBA, SMGR, TLKM, UNTR, UNVR.
