Abstract

Abstract. World Class University is considered as a way of a Telkom University to be able compete in this globalization era. One of the supporting facilities to achieve goal of becoming the World Class University is providing the student dormitories. Dormitory can be a place for learning activities, socialize, and discuss, which is expected to increase student motivation to more achievement and beneficial to the world. Feasibility study is require to determine whether the investment is worth to executed and to convince the investors. It can be viewed from a variety of indicators such as PBP, NPV, IRR, ROI, and ROE. Next  analysis is to perform a sensitivity analysis to see the effect of changing the volatile variable (inflation, revenue, proportion of debt, labor costs, and interest rates) to financial indicators such as NPV and optimal analysis to obtain the minimum number of dormitory occupants and minimum rental price dormitory that the project still feasible. Based on the results, the construction of student dormitories investment is feasible. The feasibility analysis generates a value of PBP 2 years 4 days, NPV Rp. 35,959,231,012, IRR 52.43%, ROI 13.93%, and ROE 39.79%. Sequentially, the variables that influence the change in NPV is inflation, revenue, proportion of debt, labor costs, and interest rates. Minimum number of dormitory occupied is 82% or 1542 students and minimum rental price dormitory is Rp. 5,200,000 per year. Implementation of this dormitory building process starts from feasibility analysis, bank selection and loan process, contractor selection, and process construction includes build structures, architectural, mechanical and electrical. This dormitory construction project can be completed within 16 months. Recommendation for this project,  to increase the value of NPV, the company must have the ability to well negotiate with the investor in order to get maximum the proportion of debt, because of the cost of debt for the project is lower than the cost of equity.Keywords : Dormitory,  NPV, IRR, sensitivity, optimal

Abstract

Understory plants are a group of plants that form a layer near the surface of the soil. One of the functions of undergrowth is as a ground cover which contributes to increasing the organic matter content in the soil. This research was conducted in November 2023 in the garden behind the KH. Hasyim Asy'ari Building, Jakarta State University. The aim of this research is to determine the diversity of understory plants found in the Jakarta State University environment. The research method used was a survey using a sampling technique with a quadratic method. There are 4 types of undergrowth in the garden behind the KH. Hasyim Asy'ari Building, namely Cyanthillium cineroum, Pilosela officinarum, Eclipta prostrata, and Cynodon dactylon. The results of the calculation of the Shannon-Wiener diversity index based on its classification show that the garden behind the KH. Hasyim Asy'ari Building, Jakarta State University has a low level of understory plant diversity.

Abstract

Parkia speciosa ethanol leaves extract contains flavonoid, tannin, and terpen as ulcus peptic remedy. These compounds exhibit limited activity in the stomach due to the short gastric residence time following oral administration. The formulation of gastroretentive tablets can overcome this limitation. This research aims to control the prolonged release of drugs in the stomach to increase bioavailability and characterize the ethanol leaves extract. Extraction was carried out by maceration using ethanol, followed by standardization based on specific and non-specific parameters extract. Gastroretentive tablet was formulated with combination of HPMC-K4M and chitosan using factorial design 22. Effects of compositional factors and their interactions on gastroretentive tablet was observed on hardness, friability, floating lag/duration time, swelling index, and mucoadhesive time. Results standardization extract showed that extract met the required criteria for both specific parameters (organoleptic properties and phytochemical screening) and non-specific parameters (moisture content, loss on drying, water/ethanol-soluble extract content). Based on with DX®10 analysis, the optimum formulation was achieved with 20.25% of HPMC-K4M and 10.26% of chitosan. The analysis of the optimum formulation characteristics was as follows: friability (0.22%), hardness (29.53 N), mucoadhesive time (22.86 hours), floating lag/duration time (27.54 minutes; 12 hours), and swelling index (312.82%). Result revealed that gastroretentive tablets formulated with ethanol extract of Parkia speciosa leaves improve gastric residence duration and promote better bioavailability.

Abstract

Penyakit cacingan masih menjadi salah satu masalah kesehatan yang sering terjadi pada anak-anak di Indonesia. Kurangnya pengetahuan ibu mengenai penggunaan obat cacing dapat menyebabkan pemberian obat yang tidak tepat dan meningkatkan risiko terjadinya infeksi cacing berulang. Penelitian ini bertujuan untuk mengetahui gambaran tingkat pengetahuan ibu tentang penggunaan obat cacing pada anak di wilayah kerja Puskesmas Muara Bangkahulu Kota Bengkulu. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kuantitatif. Pengambilan data dilakukan menggunakan instrumen kuesioner yang telah disusun berdasarkan indikator pengetahuan tentang penggunaan obat cacing. Sampel penelitian berjumlah 78 responden yang merupakan ibu yang memiliki anak usia 3-12 tahun dan dipilih menggunakan teknik purposive sampling. Data dianalisis secara univariat dan disajikan dalam bentuk distribusi frekuensi dan persentase. Hasil penelitian menunjukkan bahwa tingkat pengetahuan responden kategori baik sebanyak 21 responden (27%), kategori cukup sebanyak 26 responden (33%), dan kategori kurang sebanyak 31 responden (40%). Hasil tersebut menunjukkan bahwa sebagian besar responden memiliki tingkat pengetahuan yang masih kurang mengenai penggunaan obat cacing pada anak. Kesimpulan penelitian ini menunjukkan bahwa tingkat pengetahuan ibu tentang penggunaan obat cacing pada anak di wilayah kerja Puskesmas Muara Bangkahulu Kota Bengkulu masih tergolong kurang sehingga diperlukan peningkatan edukasi kesehatan kepada masyarakat mengenai penggunaan obat cacing yang benar.

Abstract

Staphylococcus aureus merupakan bakteri penyebab infeksi yang masih menjadi masalah kesehatan, sehingga diperlukan alternatif antibakteri dari bahan alam. Kulit buah kopi robusta (Coffea canephora) dan bunga kecombrang (Etlingera elatior) diketahui mengandung senyawa metabolit sekunder yang berpotensi sebagai antibakteri. Penelitian ini bertujuan untuk mengetahui aktivitas antibakteri kombinasi ekstrak etanol kulit buah kopi robusta dan bunga kecombrang terhadap Staphylococcus aureus. Metode penelitian meliputi ekstraksi dengan metode maserasi menggunakan etanol 70% serta uji aktivitas antibakteri dengan metode difusi cakram. Parameter yang diamati adalah diameter zona hambat. Hasil penelitian menunjukkan bahwa kombinasi ekstrak memiliki aktivitas antibakteri terhadap Staphylococcus aureus yang meningkat seiring dengan kenaikan konsentrasi, dengan kategori daya hambat dari lemah hingga kuat. Simpulan penelitian ini menunjukkan bahwa kombinasi ekstrak etanol kulit buah kopi robusta dan bunga kecombrang memiliki aktivitas antibakteri terhadap Staphylococcus aureus dengan efektivitas terbaik pada konsentrasi tinggi.
