Abstract

Lactic Acid Bacteria (LAB) are gram-positive bacteria that are rod or round in shape, do not form spores, and do not have cytochromes. LAB can be isolated from fermented food products. LAB is useful to inhibit the growth of pathogenic bacteria so that they are potential antibacterial sources. The purpose of this study was to isolate LAB from the traditional food Dali Ni Horbo, continued with characterization, antimicrobial testing, and sensitivity testing towards several antibiotics. From the results of the study, the number of colonies obtained was 2.4 x 107 CFU/mL. 6 isolates were randomly selected, coded as isolates UPDH1, UPDH2, UPDH3, UPDH4, UPDH5, UPDH6, respectively. Biochemical characterization showed that the isolates were gram-positive and catalase-negative bacteria.  Results of antibiotic sensitivity testing using 6 antibiotics, namely amoxicillin (AML), erythromycin (E), oxacillin (OX), ofloxacin (OFX), cefotaxime (CTX), and gentamicin (CN), showed that all the isolates were resistant to CTX. The UPDH1 isolate was resistant to AML and OX. The UPDH3, UPDH5, and UPDH6 isolates were resistant to AML, and the UPDH4 isolate was resistant to E, OFX, CTX, CN, and OX. Antimicrobial tests used the disk diffusion method against Escherichia coli and Staphylococcus aureus. The UPDH2 isolate, gave an inhibition zone of 6.7 mm, and UPDH5 and UPDH6 gave inhibition zones of 7.6 mm and 8.5 mm respectively, against E. coli. Microbial inhibition tests against S. aureus by UPDH1, UPDH2, UPDH5 and UPDH6 gave inhibition zones of 13.5 mm, 9.0 mm, 12.1 mm and 12 mm respectively. From the results in this research it can be concluded that the traditional food Dali Ni Horbo is a potential source of probiotics.

Abstract

Quality public service is a very important aspect to create good governance in the region. The success of implementing public policy does not only depend on the content of the regulation, but also on how the policy can be implemented in adaptive, responsive, and community satisfaction-focused service practices. This article aims to examine the effectiveness of implementing public service policies and the level of community satisfaction with services in Koto Tangah District, Padang City. The approach used in this article is a literature review that examines various reference sources. The results of the discussion show that public services in Koto Tangah District, Padang City still face a number of obstacles related to efficiency, speed of process, and openness of information to the public. This finding underlines the urgency of continuous evaluation of community needs and consistent improvement in the quality of public service management.

Abstract

Penelitian ini bertujuan untuk mengetahui bagaimana penerapan green accounting dapat meningkatkan kualitas sustainability reporting pada perusahaan. Metode penelitian yang digunakan adalah Systematic Literature Review (SLR) dengan pendekatan PRISMA, yang melibatkan penelusuran dan analisis terhadap 15 artikel ilmiah relevan yang dipublikasikan pada tahun 2020–2025 melalui database Google Scholar. Hasil penelitian menunjukkan bahwa green accounting berkontribusi positif dalam penyusunan sustainability reporting karena mampu memberikan data kuantitatif terkait dampak lingkungan perusahaan, meningkatkan akuntabilitas, transparansi, dan kepercayaan pemangku kepentingan. Simpulan penelitian ini menyatakan bahwa green accounting tidak hanya meningkatkan kualitas pelaporan keberlanjutan, tetapi juga mendukung kinerja keuangan dan reputasi perusahaan secara jangka panjang, meskipun masih menghadapi tantangan dalam implementasinya seperti keterbatasan regulasi dan sumber daya manusia yang kompeten.   Kata Kunci: Green Accounting, Sustainability Reporting, Akuntansi Lingkungan, Tanggung Jawab Sosial

Abstract

This paper presents an in-depth analysis of the Jowata architectural concept, designed as a net zero building through the integration of multiple renewable energy systems. Located in Kota Baru Parahyangan, Bandung, the design incorporates passive, active, and renewable energy strategies, focusing on solar photovoltaic (PV) panels, wind turbines, and pico hydro systems to meet the building’s energy needs. Comprehensive simulations, including Global Horizontal Irradiation (GHI) and wind speed analyses, were conducted to optimize the placement and efficiency of these technologies. The Jowata Grid System, supported by the local energy grid, achieves a 71.5% renewable energy offset, resulting in annual CO₂ emissions savings of approximately 23,987 tons. The building's Energy Use Intensity (EUI) is significantly below regional benchmarks, demonstrating the efficiency of the design. This study highlights the effectiveness of combining various renewable energy sources in achieving net zero emissions and offers a blueprint for sustainable building practices in similar climatic regions.

Abstract

Perhatian merupakan fungsi kognitif penting dalam proses pembelajaran, tetapi sering terganggu oleh beban kognitif dan distraksi lingkungan. Penelitian ini bertujuan menguji efektivitas latihan mindfulness singkat berupa pernapasan sadar dalam meningkatkan perhatian mahasiswa. Penelitian ini menggunakan desain eksperimen kuantitatif pre-test–post-test dengan kelompok kontrol yang melibatkan 30 mahasiswa semester awal yang dibagi secara acak ke dalam kelompok eksperimen (latihan pernapasan sadar 10 menit) dan kelompok kontrol (membaca teks netral). Indikator perhatian diukur melalui Stroop test yang mencakup waktu reaksi dan akurasi. Analisis menggunakan Mixed ANOVA yang menunjukkan adanya peningkatan signifikan antara pre-test dan post-test pada waktu reaksi (p = .012; η² = .203) dan akurasi (p = .004; η² = .257), meskipun tidak ditemukan interaksi signifikan antara waktu dan kelompok. Hasil ini mengindikasikan bahwa latihan mindfulness singkat berpotensi meningkatkan perhatian mahasiswa, meskipun tidak secara eksklusif membedakan kinerja antar kelompok.Perhatian merupakan fungsi kognitif penting dalam proses pembelajaran, tetapi sering terganggu oleh beban kognitif dan distraksi lingkungan.
