Abstract

One alternative to solving the problem of wastewater treatment is to treat wastewater using Moringa seeds as a natural coagulant. Moringa seeds contain the bioactive compound rhamnosyloxy-benzil isothiocyanate, which can adsorb and neutralize mud and metal particles contained in suspension waste with dirt particles floating in water, so it has very potential to be used as a natural coagulant to clean water.This research was conducted to determine the method of wastewater treatment by using Moringa Oleifera Seeds for Phosphate (PO4) Content in Hospital Wastewater and calculating the difference in weight variations of Moringa oleifera seeds (1000, 1500, and 2000 mg / L) with deposition time (15 minutes). This type of research is quantitative research with true experimental research. The research design used was a randomized control-group pretest-posttest design.The results showed that in the range of observations made, the weight of Moringa seed powder as an effective coagulant was 2000 mg / L hospital wastewater with a deposition time of 15 minutes capable of removing phosphate levels by 28.77%.

Abstract

Developments in health science and technology show an increasing need for more efficient and effective health devices. One innovation in this field is the Narrowband Ultraviolet B (NB-UVB) phototherapy device, which is effective in the treatment of psoriasis and vitiligo. However, conventional tools are often out of reach for patients who are far from health service centers. This research aims to design and create a portable NB-UVB phototherapy device equipped with an Arduino-based HC-SR04 ultrasonic sensor control system, which can be used for psoriasis and vitiligo sufferers anywhere and anytime. The methodology used is Research and Development which is the design of tools for the development of previous tools. The result of this research is a portable NB-UVB phototherapy device that is easy to use and is able to reach skin areas that are difficult to treat with conventional instruments with a maximum illumination distance of 3 cm, as well as test results on a timer of 5 minutes, 15 minutes, 30 minutes.With results, 5 minutes has an accuracy of 99.84%, 15 minutes has an accuracy of 99.47%, and 30 minutes has an accuracy of 98.57%. The author's suggestion in research is to carry out measurements using a UV Meter to determine the intensity of the UV radiation produced, so that the dose to be used can be adjusted, and to optimize the radiation distance and to reduce the workload on the user.
