The research will utilize secondary such as financial reports, annual reports, public expose from idx.co.id, and other literature sources. The methodology to process the data is Discounted Cash Flow valuation method to find the actual intrinsic value and value-added intrinsic value, to find the fair value using Net Asset Value valuation method. The added value is a proposal to developing housing projects for Generation Z with goal to increase the company share price. The result is the stock fair value to be IDR 1,312 – 2,554. Finally, the author will determine if the stock of PT B is undervalued or overvalued based on the research results.

In Citeureup Sub-district, Bogor, Indonesia, many MSMEs have developed their business around the metal sector. Despite many MSMEs operating in the area, there still a lack of OHS implementation. This study aimed to create an online database regarding business profile, OHS implementation, and health symptoms among workers at surveyed MSMEs. The survey was conducted to the 56 MSMEs located in Pasir Mukti Village, Citeureup District, Bogor Regency, Indonesia. The majority of MSMEs are micro-sized enterprises with 1-4 workers and produce metal products. Only 2% of MSMEs have an OHS commitment that is formally signed by the employer. The most prevalent hazards found in MSMEs were noise (71%), dust exposure (57%), and vibration (45%). Awkward postures and manual handlings are also commonly found in MSMEs. The most prevalent health symptom commonly experienced by workers is the soreness of the musculoskeletal system. There are six primary healthcare facilities located around MSMEs, yet only one facility operates for 24 hours and only 2 out of 6 facilities have an ambulance for emergencies.

The purpose of this research is to carry out analysis regarding the influence of Operating Cash Flow Growth, Inflation, Earning per Share Ratio, Debt to Equity Ratio, and Current Ratio on Stock Returns in building, property, and real estate construction companies. In the implementation of this research, the population used is building construction companies, property, and real estate which are listed on the Indonesia Stock Exchange for the period 2016 to 2019. In this study, the sampling technique is using purposive sampling. The data used are quantitative secondary data. The data analysis method is multiple linear regression. Based on the results of the analysis, it is determined that simultaneously the independent variable Debt Equity Ratio, the independent variable Current Ratio, the independent variable Earning per Share, the independent variable Dividend Payout Ratio, Inflation and Growth in Operating Cash Flow do not provide contribution to the influence of Stock Return. Partially the results of the analysis determine that the independent variable of the Debt Equity Ratio contributes a significant effect on stock returns, meanwhile for the independent variables of Current Ratio, Dividend Payout Ratio, Earning per Share, Inflation and Operating Cash Flow Growth did not contribute significantly to Stock Returns. Keywords: Debt Equity Ratio, Current Ratio, Dividend Payout Ratio, Earning Per Share, Inflation, Operating Cash Flow Growth and Stock Returns

<strong><em>Background:</em></strong><em> Impression material is a material that is used to negatively replicate a patient's tooth structure and periodontal, and it is preferable to sterilize the negative model first before the casting process to avoid cross-contamination between the dentist and the patient. Then casts are made from the impression using type III gypsum, producing diagnostic cast or working cast. Ultraviolet-C (UV-C) sterilization was introduced as the lastest sterilization technology from UV rays with an effectiveness rate of 99.9% in lysing germs, viruses, and fungi. The wavelength of UV-C light itself is also the smallest at 200-270 nm compared to UV-A 320-400nm and UV-B 270-320nm. <strong>Objective:</strong> To determine the effect of UV-C sterilization on the changes in dimension of alginate impressions. <strong>Methods:</strong> The type of this research was experimental laboratory research. The samples were taken from the maxillary model which were divided into 2 groups, namely (A) the treatment group where cast was irradiated with UV-C and (B) the control group where casts were sprayed with disinfectant. Samples of the treatment and control groups were both sterilized first before casted. For the treatment group, casts were put in a UV-C box for 10 minutes. For the control group, casts were sprayed with disinfectant, then covered with a moistened tissue and put into a plastic seal. <strong>Result:</strong> UV-C sterilization did not show significant changes toward dimensional changes of alginate impressions. <strong>Conclusion:</strong> UV-C sterilization can be used to sterilize alginate impression materials because it does not cause significant dimensional changes of the impression</em>

Monkeypox adalah penyakit yang pertama kali ditemukan pada tahun 1958 di Denmark ketika ada dua kasus seperti cacar pada koloni kera yang dipelihara untuk penelitian, sehingga cacar ini dinamakan ‘Monkeypox’. GLCM adalah suatu matriks yang merepresentasikan frekuensi munculnya pasangan dua piksel dengan intensitas keabuan, jarak dan sudut dan Random Forest adalah salah satu metode klasifikasi yang merupakan kombinasi   dari setiap pohon yang baik kemudian dikombinasikan ke dalam satu model. Penelitian ini menggunakan public dataset monkeypox dan non-monkeypox dan memiliki gambar berjumlah 3.192 dibagi menjadi data uji dan data latih dengan rasio 60:40, 70:30, 80:20, dan 90:10. Hasil dari fitur tekstur GLCM dilakukan pengujian dengan metode Random Forest menggunakan parameter n_estimator = 100, 500, dan 1000. Dari empat pengujian yang sudah dilakukan, disimpulkan bahwa n_estimator terbaik adalah 100 dengan proporsi rasio dataset 90:10, yang menghasilkan nilai accuracy sebesar 77%, precision 77% ,recall 77%, dan f1-score 76,5%.
