As an important means of sea transportation for the distribution of goods and human mobility between islands, ships require a reliable prime mover to avoid wear or damage, especially when overspeeding occurs which can result in fire. Therefore, a prototype was created that uses an IR Obstacle sensor to monitor the RPM speed of the rotating engine. By using Arduino Uno as a processor, this prototype is able to display the RPM value on the LCD and provide a signal in the form of a green light if the speed is below 4000 Rpm, as well as a red light and buzzer sound if overspeed occurs above 4000 Rpm, followed by the engine turning off after 15 seconds. Testing shows that this prototype has a high level of accuracy, with a difference between 0.08% to 2.73% and an average difference of 1.003%.

Chinese Betel Plant (Paperomia pellucida) is an herbal plant that has benefits for treating diseases such as acne, ulcers, antidiabetic, antioxidant, anti-inflammatory, antimicrobial, and antibacterial. The content of bioactive compounds from Chinese betel include alkaloids, flavonoids, steroids, saponins, tannins, triterpenoids, and carbohydrates. The aim The purpose of this study was to determine the effect of steeping Chinese betel and  on reducing blood glucose levels in male mice. This method used is an experimental method at the Pharmacology Laboratory D3 Pharmacy FMIPA Bengkulu University. The test animals used were three groups, namely the positive control treatment group that received glibenclamide, the negative control treatment group received aquadest, and the 2% Chinese betel steeping treatment group. The results showed that Chinese betel curd was reduced from 125 mg/dl to 93 mg/dl and there was no hypoglycemic decrease in blood glucose due to glibenclamide. From the results of the study it can be concluded that the administration of Chinese betel and glibenclamide steeping is effective in lowering blood glucose levels in male mice.

Furniture raw materials are still a major challenge in the industry, in line with the wishes of consumers to get good quality raw materials and soaring export demand, so there is a need for a control process to monitor the value of products using forecasting.

Malaria adalah penyakit menular yang disebabkan oleh plasmodium yang ditularkan melalui nyamuk Anopheles betina. Terdapat 4 jenis plasmodium malaria yaitu Plasmodium malariae, Plasmodium ovale, Plasmodium vivax dan Plasmodium falciperum. Pada tahun 2021 penyakit ini menyumbang hampir 80% dari seluruh kematian akibat malaria di Wilayah Afrika.  Parasit ini juga dominan di hotspot malaria lainnya, termasuk wilayah WHO di Asia Tenggara dan Asia Selatan, Mediterania Timur, dan Pasifik Barat, Amerika Tengah dan Amerika Selatan bagian utara. Tujuan dari penelitian ini yaitu mengetahui faktor risiko terjadinya malaria secara global. Metode penelitian ini menggunakan metode observasional dengan literature review dalam rangka mengidentifikasi faktor-faktor penyebab terjadinya kasus malaria secara global. Faktor resiko penyakit malaria dapat diklasifikasikan menjadi beberapa faktor seperti faktor Lingkungan tempat tinggal, Mobilitas manusia, Praktek pencegahan, Ekonomi, Gender dan usia.

Introduction: Water quality parameters are indicated by the presence of E. coli bacteria. These bacteria come from human feces, warm-blooded animals, and non-fecal coliforms. Decree of the Health Minister of the Republic of Indonesia Number 907/MENKES/VII/2002 concerning requirements and supervision of drinking water quality states that good drinking water has a zero total coliform and fecal coliform. Methods: This research uses a descriptive approach with a cross-sectional design. It aims to determine the quality of water sources in Sulkatan village. Ten (10) water sources were used as the samples using total sampling method. The collected samples were then taken to the laboratory to be tested with a series of MPN tests Results and Discussion: The results show that the amount of Escherichia coli bacteria in water samples in Sulkatan Village is 0MPN/100 ml. It is owing to the location of the water source that is far from industrial activities, household waste and residential areas. Conclusion: The quality of the tested well-water samples is good and within normal limits in accordance with the Decree of the Health Minister of the Republic of Indonesia Number 907/MENKES/VII/2002
 
 

College Students' interest in participating in organizational activities is a current topic in the university environment. The existence of organizations can be seen from students' interest in joining organizations, one of which is in the Social Sciences Education Study Program, Faculty of Social Sciences, Jakarta State University.

At Republic of Indonesia State Civil Service Agency in carrying out work, it is often found that problems both software and hardware are installed in the computer and must be resolved immediately. However, the handling of problems is still not good, where in the process of reporting complaints and requests, you still have to go by telephone or come directly to the IT staff office to notify complaints, as well as in manual records that affect company performance. All recording reports and problem calculations are still manual. This can have a negative effect, namely: there are problems that are at risk of being recorded repeatedly, so it takes a long time to provide reports to managers. Therefore, the authors submit a helpdesk information system application to solve the problems of complaints and employee requests so that they can be resolved quickly and can be handled properly as well as recording reports that are well recorded. In developing this helpdesk information system, the author uses an object-oriented methodology, namely the iteration waterfall, which is modeled using UML (Unified Modeling Language). The tools used are XAMPP as a web server, PHP as a programming language and MySQL as a database. With this system, it is hoped that it can make it easier for employees to report complaints as well as get solutions to the problems they are complaining about and also make it easier for IT staff to automatically generate reports in the system.

In public service offices in the government, special areas or rooms are provided for smoking. At the Kendal District Court Class 1B the smoking room or smoking area still uses air ventilation and fans to neutralize cigarette smoke. As a result, the smoke that is exposed to the fan in the smoking room spreads out and disturbs the health of the surrounding community or disrupts the activities of employees at the Kendal Class 1B District Court. In this case, the Kendal Class 1B District Court, especially this smoking area, needs to be handled, namely making a device that can filter cigarette smoke and monitor the condition or level of air quality in the room so that cigarette smoke does not spread outside the room and harm your health. To help the filtration system in smoking rooms, there needs to be an automatic system that is able to work when cigarette smoke in the room is at a certain level. The sensors used to detect levels of CO ( carbon monoxidant), CO2 (carbon dioxidant) in cigarette smoke are MQ-7 and MQ-135. The way this tool works, if cigarette smoke in the room reaches the threshold level of gas in the room, the fan will suck it into the filtration room, after which it will be exhaled back into the smoking room and will notify the condition of the room on the LCD monitor display.
