Abstract:Abstract: Nowadays, almost all of them use a dispenser, because of its practicality. But behind that there are several things that make the dispenser less efficient when taking drinking water from the glass, because the…
user has to press or turn the water tap in the dispenser. The working system of this tool is where the machine will run according to the commands obtained from the laser diode and the LDR sensor, the laser diode will reflect light that leads to the LDR. when the light reflected by the laser diode to the LDR is cut, it can be interpreted that the LDR and the laser diode detect or read the presence of an object in the form of a glass, automatically the two sensors instruct the controller to activate the water pump and the water pump will work to remove the water which will be filled in the glass that is placed in the dispenser with the volume of the glass used, the filling process and the end of filling will be displayed by the LCD and when filling the water the glass is full there will be a warning from the buzzer in the form of a sound. Users no longer need to press or turn the water tap when taking water from the dispenser using a glass.

Abstrak: Pada saat ini masyarakat sekarang sudah hampir semuanya menggunakan dispenser, karena kepraktisan. Namun dibalik itu semua ada beberapa hal yang membuat dispenser kurang efisien saat mengambil air minum pada gelas, karena pengguna harus menekan atau memutar keran air yang ada pada dispenser. Sistem kerja dari alat ini ialah dimana mesin akan berjalan sesuai dengan perintah yang didapat dari Dioda laser dan sensor LDR, Dioda laser akan memantulkan cahaya yang mengarah pada LDR, pada saat cahaya yang dipantulkan Dioda laser ke LDR terpotong maka dapat diartikan LDR dan Dioda laser mendeteksi atau membaca adanya benda berupa gelas, secara otomatis kedua sensor tersebut memerintahkan controller mengaktifkan pompa air dan pompa air akan bekerja mengeluarkan air yang akan diisikan pada gelas yang diletakkan pada dispenser dengan volume gelas yang digunakan, proses pengisian dan akhir pengisian akan ditampilkan oleh LCD dan saat pengisian air pada gelas penuh akan ada peringatan dari buzzer berupa bunyi. Pengguna tidak perlu lagi menekan atau memutar keran air saat mengambil air pada dispenser menggunakan gelas.

wer rating of 900 watts, making them unsuitable for use in Tomuanhollbung Village. To address this issue, the research team designed a stove that uses waste oil (35,000 kJ/kg) and incorporated embedded system technology, utilizing the French design research method. The research results indicated that by using a DC motor with specifications of 12VDC/3A, 3800 rpm, and a valve diameter of 9.7 x 9.5 x 3.3 cm, a power output of 36W was achieved, with a pressure of 288.7 Pa or 0.00289 bar and an angular velocity of 398.1 rad/s. When the burner stove was first ignited, the flame appeared yellow. With a voltage of 3.7VDC/3A, it produced a rotation of 3795 rpm, a yellow flame, a flame height of 8 cm from the stove, and a flame width diameter of approximately 18 cm. At a voltage of 3.7VDC, the pressure measured 0.000964 bar, with a flame temperature of 275°C (as measured by an infrared sensor). A voltage of 7.4VDC resulted in a pressure of 0.0192 bar and a flame temperature of 350°C, while a voltage of 11.8VDC produced a pressure of 0.0289 bar with a maximum flame temperature of 420°C. For fuel consumption over 10 minutes at 3.7VDC/3A, the flame height reached 7-10 cm, with a wind pressure of 0.000964 bar and a fuel consumption of 0.237 grams.

Abstract:Abstract: The Indonesian Red Cross or abbreviated as PMI, is one of the organizations in Indonesia engaged in the humanitarian field. PMI has branches in all cities in Indonesia such as the red cross in Asahan district.…
Currently, the Asahan district red cross has a blood donation stock of ± 100/360 cc per bag. The purpose of designing a blood group type reader is to increase the certainty of blood types that are tested by experts or medical workers from PMI Asahan, according to the testing of the tool design. This study used a qualitative type of method, namely data taken in the form of data on the condition of the blood when rhesus fluid was given, so that the data will be calibrated with the test results so that the right test results can be decided. The results of testing the device design with blood and fluids, found that blood group A+ got an LDR value of 19.5 and 4 with a bina-ry condition of 101, while for blood group B+ got an LDR value of 19, 4 and 4 with a bi-nary condition of 011, blood group AB+ got a value LDR 19, 3 and 4 with binary condi-tion 111, blood type O+ found LDR values 19, 2 and 4 with binary condition 001. Mean-while for basic conditions, or not detecting blood type, LDR conditions 20, <=4, <=4 and binary value is 000. After testing, all results of testing the design of the tool are in full ac-cordance with the results of the conclusions of the PMI Asahan medical personnel about the type of blood group
