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

This study aimed to determine the formula of anti-aging cream using lemongrass leaf extract. The treatment by giving respondents lemongrass leaf extract and using moisture, evenness, pore, spot, and wrinkle as parameters. Human skin provides protection on the surface of the body against the influence of the surrounding environment. Skin can experience aging, especially in areas that are often exposed to direct sunlight such as the face, neck, upper arms, and hands. Aging is a process experienced by humans in their 30s whose functions in the human body are decreasing, for example, thinning skin, wrinkles, rough skin, and dark spots on the face. Treatment to prevent aging of the skin by using an antioxidant product such as flavonoids because it has the function of preventing or neutralizing free radicals. In Indonesia, several species of plants can be found that function as food and cosmetic ingredients. The lemongrass leaf extract which contains antiaging are Alkaloids, Flavonoids, and Tannins. The data were analysed by using the Kolmogorov-Smirnov method to determine homogeneity and normality. Then, if the data is normal, it is continued to be analysed using the One-Way ANOVA method to determine the average difference between groups. There is a difference between treatments, and it is continued with the Post-hoc Tukey HSD test. The higher the concentration of extract used, the greater the anti-aging productivity formed. It is concluded, the best anti-aging effect is a concentration of 9% with increase in moisture, evenness, pore reduction, reducing spots and wrinkles.

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.

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

Persons with disabilities in Bitung City, particularly the Deaf community, continue to face limited access to education, employment, and social participation. In response, PT Pertamina Patra Niaga, through its Corporate Social and Environmental Responsibility (TJSL) program, implemented a participatory and collaborative approach that included surveys, interviews, focus group discussions (FGDs), and observations, accompanied by pre- and post-test evaluations to measure participants' competency improvement. The PADU Program offers five main training modules — Sign Language, Souvenir Production, Barista Skills, Shoe Care, and Digital Creativity — tailored to the diverse types of disabilities among participants. The results indicate an average increase of 40% in technical skills and 35% in social aspects, including self-confidence and communication. Economically, participants successfully produced approximately 200 coconut-shell souvenirs, valued at around IDR 10 million per month. The program also contributed to reducing potential emissions by up to 15 tons of CO₂ per month through the implementation of a circular economy approach. PADU contributes to SDGs 8, 10, 12, and 13, demonstrating that multi-stakeholder collaboration can foster inclusive, equitable, and sustainable social transformation for persons with disabilities. The Bitung Deaf Care Community (KALEB) established the PADU Inclusive Disability Learning Center as a community-based model for inclusive empowerment. This study employs a qualitative approach.

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.
