Abstract

The main method of preventing infections is good hand cleanliness. Bilimbi (Averrhoa bilimbi) fruits contains flavonoids, which have been tested for antibacterial activity. Polar chemicals like flavonoids are often extracted using ethanol as a solvent.  Therefore, this study aimed to formulate an ethanol extract of A. bilimbi fruits in the form of hand soap. This formulation used vegetable oils such as olive oil, coconut oil, and castor oil, which are high in fatty acids to maintain healthy skin. Antibacterial activity was carried out against Staphylococcus aureus and Escherichia coli. The extract was prepared by maceration for 5 days using an ethanol solvent. Liquid soap contained A. bilimbi fruit extracts at 5% (F1) and 10% (F2). The F1 and F2 organoleptic tests showed the preparation as a thick liquid with a distinctive coconut oil aroma, light brown (F1) and brown (F2) color. pH values of 5.8 (F1) and 5.6 (F2). Foam height stability was 71.5% (F1) and 73.1% (F2). The specific gravity for the two formulas was 1.02 g/mL. The viscosity of F1 and F2 was 137.6 cP and 163.5 cP, respectively. Inhibition power against S. aureus using the agar diffusion method by measuring the diameter of the inhibition zone showed strong (F1) and very strong (F2) categories The inhibition against S. aureus showed strong (F1) and very strong (F2) categories. While F1 has no inhibitory power against E. coli, F2 showed inhibition in the strong category. Based on our research, it can be concluded that A. bilimbi fruit extract can produce good hand soap and have bacteria-inhibiting activity. However, further formula development is still needed to obtain preparations that meet all the requirements and stability tests.

Abstract

Peningkatan peduduk di Kota Tangerang berbanding terbalik dengan ketersedian lahan pada kota ini, oleh karena itu proyek permbangunan tempat tinggal dibuat menjadi kearah vertikal atau dikenal dengan apartermen. Dalam suatu proyek konstruksi, proses penjadwalan adalah salah satu faktor penting penentu berhasil atau tidaknya proyek konstruksi tersebut. Tingkat kerberhasilan suatu proyek dapat dilihat dari waktu yang efektif, besar biaya yang efisien, dan mutu yang tepat pada produk yang dicapai. Penelitian ini dilakukan untuk mengetahui jaringan kerja dan jalur kritis pada proyek pembangunan apartemen Elevee Penthouse & Residences. Metode yang digunakan adalah metode CPM (Critical Path Method). Dengan metode ini diharapkan dapat mengetahui berapa lama waktu yang dibutuhkan untuk menyelesaikan pembangunan proyek tersebut dan memperhitungkan kemungkinan percerpatan waktu pelaksanaannya. Metode CPM dapat digunakan sebagai analisis untuk proyek yang sedang berjalan dan untuk mengetahui keadaan proyek kedepan. Berdasarkan S-curve proyek terserbut sudah berjalan hingga minggu ke 68 dengan progress 37,020%. Namun aktualnya pada minggu tersebut progress hanya mencapai 36,437% dengan deviasi -0,584%, khususnya di tower 2 pada pekerjaan instalasi precast façade lantai 10 memiliki deviasi sebesar -1,136% dan pada pekerjaan finishing lantai ground floor memiliki deviasi sebesar -0,012%. Durasi yang dijadwalkan proyek untuk tower 2 adalah 2448 hari, namun secara aktual mengalami keterlambatan 125 hari sehingga diestimasi proyek akan selesai dalam durasi 2573 hari. Setelah dievaluasi dan dianalisis dengan mengimplementasikan metoda CPM, proyek tersebut dapat diselesaikan dalam waktu 2520 hari, artinya proyek dapat dikerjakan lebih cepat 53 hari, dengan jalur kritis berada pada aktivitas A – B – F – G – H – I – K – N – O – Q – R – T – U dengan efisiensi waktu proyek sebesar 24%.

Abstract

This study explores the English literacy challenges faced by 12th-grade students in Indonesia as they prepare for the UTBK 2025, focusing on reading comprehension, vocabulary, and grammar. Using a qualitative research approach, data were collected through semi-structured interviews, focus group discussions, and classroom observations from a purposively selected sample of 20-30 students. Thematic analysis revealed that the primary challenges students face include difficulties with complex academic texts, limited vocabulary knowledge, and grammatical errors, all of which hinder their performance in the English section of the UTBK. The study further investigates the factors influencing students’ English literacy preparation, such as the quality of educational support, access to external resources (e.g., online learning platforms, tutoring), and peer support. Results indicate that students attending well-resourced schools and those utilizing additional learning resources felt more prepared. Peer learning also played a key role in overcoming literacy challenges. Moreover, students employed various coping strategies, including active reading, vocabulary-building techniques, and practice tests, to improve their skills. This study provides valuable insights for educators and policymakers seeking to improve English literacy preparation for high-stakes exams like the UTBK.

Abstract

Poverty is a complex social issue that affects many aspects of human life. This study aims to analyze the factors contributing to poverty in urban and rural areas, as well as its impact on social, economic, and environmental life. The research method used is a qualitative approach with a comparative analysis of poverty in urban and rural areas. The results of the study indicate that poverty in urban areas is primarily influenced by urbanization, unemployment, and income inequality, while in rural areas, it is more influenced by dependence on the agricultural sector, inadequate infrastructure, and low levels of education. The impacts of poverty are visible in various aspects, ranging from education, health, to excessive exploitation of natural resources. Furthermore, this study also found significant differences in the severity of poverty and the necessary solutions between urban and rural areas. Poverty alleviation requires a locally-based approach that involves cooperation between the government, NGOs, and the community, with a focus on improving access to education, health, and economic empowerment.

Abstract

In an increasingly globalized administrative landscape, English communication skills have become essential for professionals across public and private sectors. However, the communicative functions and expectations in each domain differ considerably. This study aims to compare the specific English communication needs of public and private sector administration, incorporating insights from practitioner-teachers and students in public administration and management programs. Using a comparative qualitative approach, data were collected through semi-structured interviews and classroom observations involving over ten professionals and educators, alongside student participants. Thematic analysis revealed distinct patterns: public sector communication focuses on formal documentation and bureaucratic clarity, while the private sector emphasizes interactive, client-facing communication. Despite these differences, both sectors share foundational skill demands such as meeting participation and professional writing. Furthermore, practitioner-teachers were found to enhance instructional relevance by integrating real-world experience into ESP classrooms. The study concludes that English instruction in administrative education should be tailored to reflect sector-specific needs and supported by practice-informed pedagogy.

Abstract

These days, technology-based learning is essential since it provides media and tools for the process of teaching and learning. However, in addition to all of the effort that teachers put into integrating technology into the classroom, other factors must be taken into consideration, one of which is the teacher's role. The purpose of this study was to find out the efficacy of the roles and digital learning resources that English teachers employ in their classes. The responders to this study were 5 English teachers from various junior high schools in Tebing Tinggi, North Sumatera, in the academic year 2022/2023. In addition, 9 students from each class also involved as the respondents. So the total number of students that participated in this study was 45. A qualitative approach was taken in conducting this study. The researcher used interviews and observation as instruments to get the data required for this study. The results of this study showed that teachers additionally played the roles that were necessary for technology-based learning, including as the operators, mentors for technology use, organizers of technology-based learning, and monitors of digital learning.
