Abstract

This research aims to facilitate a more even fish maturation process due to the rotation process of the fish rack which is regulated by the system in Mechanism Timer and Temperature at the Fish Smoking machine. The smoking machine can also make it easier for people to smoke fish. It has an overall height of 150 cm, door height of 110 cm, Fuel tank height of 30 cm, and foot height of 10 cm, in the fish smoking room there are 2 fish tray racks. The fuel for the smoking machine uses coconut husk and the coconut shell is equipped with a Digital Thermostat to read the temperature in the room and is also equipped with a Thermohygro to read the humidity in the room. The working principle of this tool is that the first step is to connect the multi-plug to the power source, from the power source to the MCB, the MCB gets current and when the MCB is turned on, the current enters the Push Button Switch, and when the Push Button On is pressed, the red light turns on, indicating there is the current that enters the Digital Thermostat digital from the Thermostat to the plug terminal, from the plug terminal to the Timer and from the Timer to the Power Supply From the Power Supply changes the current from 220 volts to 12 volts when the green light is on then the Power Window functions by moving the fish rack tray.

Abstract

Sound system merupakan alat bantu penguat suara yang banyak dipergunakan oleh masyarakat untuk kebutuhan tertentu. Seringkali suara yang dihasilkan dari perangkat sound system tersebut kurang jernih atau timbul derau (noise). Ada dua faktor yang menjadi penyebab timbulnya noise yakni faktor internal dan faktor eksternal sehingga untuk menghasilkan suara yang jernih membutuhkan filterring agar suara yang dihasilkan tidak menimbulkan noise. Filter noise yang digunakan adalah menggunakan automatic mixing untuk mengurangi nilai amplitudo pada frekuensi yang dikeluarkan dengan mentunning potensiometer secara otomatis. Pada umumnya pengguna sound system akan mentunning dengan cara manual untuk mendapatkan nilai amplitudo dan frekuensi yang diinginkan. Melalui perancangan automatic mixing audio sebagai pereduksi noise pada sound system menggunakan mikrokontroler arduino maka diharapkan pengguna dapat mudah memilih genre music dalam operasional sound system yang diinginkan serta dapat mereduksi noise secara otomatis. Penggunaan filter FIR (Finite Impulse Response) bertujuan untuk mengurangi noise yang berlebihan sehingga suara yang dihasilkan dapat dioptimalkan dengan baik. Hasil dari penelitian kali ini diperoleh bahwa terdapat pengaruh yang signifikan antara korelasi variabel independen (jarak percobaan dan jenis musik) terhadap variabel dependen (noise) serta terdapat kelebihan dan kekurangan antara Automatic Mixing dengan filter FIR. Adapun timbulan noise paling besar pada penelitian kali ini terdapat pada percobaan 3 dengan jarak 40 cm dan untuk genre musik vocal.

Abstract

Malaria is an infectious disease transmitted by the Anopheles mosquito vector and is still a public health problem in Indonesia. The morbidity and mortality rates due to malaria are high, and have the potential to cause Extraordinary Events (KLB). The existence of malaria vectors is influenced by physical, biological, and socio-cultural environmental factors, so that control efforts require cross-sectoral and programmatic cooperation. Along with the national malaria elimination target in 2030, Bengkulu Province has had four districts/cities achieve elimination status, one of which is Bengkulu City. To maintain this status, strengthening environmental surveillance is crucial.This study aims to map the type and distribution of breeding sites and the presence of Anopheles sp. larvae in the working area of Sidomulyo Health Center, Bengkulu City. This study used spatial analysis with the help of Geographic Information System (GIS) to produce effective visualization and illustrate the relationship between ecosystem characteristics and vector presence. Coordinates of breeding sites were identified and the presence of Anopheles sp. larvae was observed.From the mapping results, 12 potential breeding sites were found, consisting of 6 ditches, 3 swamps, and 3 ponds. Four of them were confirmed positive for Anopheles sp. It is recommended that surveillance officers and malaria program managers conduct routine monitoring at positive sites as well as malaria screening for migrants from endemic areas who live temporarily or permanently in the Sidomulyo Puskesmas area.

Abstract

Clean water is a fundamental need that must be fulfilled at all times. Approximately 70% of the human body consists of water (Kumala et al., 2029). However, the availability of clean water that is safe for human consumption is very limited. Clean water intended for consumption must meet health standards, including physical, chemical, and bacteriological requirements (Fadli, 2022; Ministry of Health, 2023; Hiola et al., 2022). The most commonly used clean water facilities in both urban and rural areas are dug wells (FS et al., 2022). Contamination of clean water in dug wells is influenced not only by the presence and quantity of pollution sources such as seepage from latrines, animal pens, and domestic wastewater drainage systems (SPAL) surrounding the well but also by the physical construction of the well, including the height of the well curb, well walls, well flooring, SPAL condition, and the distance between the well and pollution sources (Sari, 2021; Asih, 2019; Agrelo, 2020; Rohmania et al., 2022).This study aims to describe the quality of dug well water based on physical parameters and acidity level (pH) in RT 12 and RT 14 at Grand Korpri Housing, Bentiring Subdistrict, Bengkulu City. The research used a descriptive method with a total of 13 dug well samples selected using purposive sampling. Examinations were conducted on physical parameters (TDS, turbidity, odor, temperature) and chemical parameters (pH) using a test kit, and the results were compared with the clean water quality standards based on Ministry of Health Regulation No. 2 of 2023, followed by an intervention using alum (tawas).The results showed that the TDS parameter met the quality standard. Meanwhile, 23.1% of turbidity parameters did not meet the standard, 38.5% of odor parameters did not meet the standard, 7.7% of temperature parameters did not meet the standard, and the pH parameter did not meet the standard. The intervention using 100 grams of alum per well resulted in a decrease in turbidity levels from 85.2 to 25.1 NTU, while TDS, pH, odor, and temperature showed no change.
