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 research was conducted to examine the steps and techniques for evaluating Islamic Religious Education learning outcomes. The research is qualitative in nature by analyzing several literature books and as the main data source. The results of the research are the steps for evaluating learning outcomes, namely, preparing a plan for evaluating learning outcomes, collecting data, verifying data, processing and analyzing data, providing interpretations and drawing conclusions, and then continuing with the evaluation results. Meanwhile, learning outcomes evaluation techniques are test techniques, objective techniques and non-test techniques. The research results state that the diagnostic assessment aims to diagnose students' basic abilities and determine students' initial conditions. Diagnostic assessments are divided into non-cognitive diagnostic assessments and cognitive diagnostic assessments. The Merdeka Belajar curriculum wants to create a happy learning atmosphere.

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.
