Abstract

The level of accuracy of a measuring instrument is expected to be good because it is expected to provide information that can be used as a reference and benchmark in research and application in public life. The use of a compass measuring device in determining the direction of the wind and the location of the magned earth may vary from year to year such as the compass analog and digital. Both offer good reading results with the same way of working utilizing magnetic poles north and south as a reference point. HMC 5883L sensor is one measuring tool that is able to detect the direction of the compass with the same way of working from analog and digital compasses. By using Arduino Uno as a microcontroller as a central control that is able to change the information received from the HMC 5883L sensor into an easy-to-understand form of data. Qibla is more accurate by comparing the reading results of both. The results of the HMC 5883L compass sensor reading will be visualized in the form of the pointer, the pointer light and will be changed in numerical form. All data changed in the form of work is the result of an order from Arduino Uno received from the HMC 58883L sensor. A total of eight LED lights are used as a pointer to the compass and are connected with data obtained from the sensor.

Abstract

Humans have always tried to create new materials that have a strong, rigid, lightweight, and inexpensive construction. The honeycomb structure is a man-made material that has a honeycomb geometry to minimize the amount of material used, to achieve a minimum weight so that a light mass is obtained for the construction. The honeycomb structure is commonly used in aerospace, transportation, F1 competitions, and many other industries. In general, the purpose of this study is to determine the level of deformation, strain stress that occurs in the honeycomb structure that is statically tested. Honeycomb is made using aluminum material with a thickness of 0.4 mm and then formed with a hexagonal size that varies with 2 mm, 4 mm, and 6 mm. This compressive test is carried out using a Universal Testing Machine with 2 positions namely horizontal and vertical. The specimen is pressed until it has a visible point on the graph. The results that have been found from this compressive test in the form of deformation values and the maximum force acting on the specimen. From the results of the comparison of hexagonal size variations, it can be concluded that the larger the hexagonal honeycomb size, the greater the deformation that occurs.

Abstract

Penggunaan mesin pembeku saat ini sudah menjadi kebutuhan masayarakat luas, dikarenakan sangat membantu manusia dalam kehidupan sehari-hari. Beban pendingin yang diberikan sangat mempengaruhi kinerja mesin Pembeku, baik dari konsumsi energi listrik maupun kemampuan yang akan meningkatkan waktu pemakaian sistem yang lebih lama. Semakin besar beban pendingin akan meningkatkan penggunaan energi listrik saat pengoperasian. Hal ini sangat megkhawatirkan dimasa kedapanya dimana isu menipisnya sumber energi fosil yang saat ini menjadi prioritas penghasil energi listrik semakin banyak  dan memenuhi media. Beberapa tahun terakhir, energi matahari diisukan menajadi jawaban dari masalah tersebut. Dimana energi panas dari matahari dimanfaatkan untuk menggerakkan proton dan elektron pada suatu media penel surya untuk menghasilkan energi listrik yang dapat dimanfaatkan untuk kebutuhaan masyarakat banyak. Hal ini menjadai daya tarik peneliti untuk membuat sebuah inovasi pemanfaatan energi matahari pada sebuah sistem lemari pembeku. Dilihat dari roadmap penelitian terkait dengan energi matahari dan sistem kompresi uap pada lemari pemebeku yang dilansir beberapa tahun terakhir, belum banyak dilakukan inovasi pembaruan dalam penggunaan sumber energinya. Beban pendingin yang akan digunakan akan disesuaikan dengan kapasitas dari sumber energi yang digunakan yaitu berdaya 410 WP. Dengan kapasitas lemari pembeku yang digunakan berdaya 1/4 PK yang akan ditingkatkan kemapuannya/efisiensi untuk dapat digunakan dan menggantikan lemari pembeku berenergi listrik berbayar. Hal ini diharapkan berguna bagi khalayak masyarakat dan menyumbang ilmu pengetahuan dan membantu mewujudkan roadmap universitas dimasa kedepan.

Abstract

Honeycomb structure is a natural or man-made structure (material) that has the geometry of the honeycomb, in addition to being directed to the mass of light construction material, also obtained a degree of flexibility from the selection of such materials. The purpose of this study is to analyze the ability of energy absorption in static press testing. Energy absorption is a method of how an object attenuated due to external pressure. Energy absorption testing is conducted with static press tests, aluminum plate test objects in the form of honeycomb structures with different hexagonal size variations. This test will compare the results of voltage data – strain and energy suppression in each specimen that has been tested to see which is more efficient among three specimens of different hexagonal sizes. The final results of this test will be displayed using a voltage graph – horizontal and vertical position strain and energy absorption capability with horizontal and vertical testing positions. Therefore, the largest energy absorption result is in the horizontal testing position with a hexagonal size of 2 mm, and the smallest energy absorption is found in the vertical testing position with a hexagonal size of 6 mm.

The honeycomb structure is a man-made material that has a honeycomb geometry to minimize the amount of material used, to achieve a minimum weight so that a light mass is obtained for the construction. This honeycomb structure is commonly used in aerospace applications, transportation, F1 racing and many other industries.

The honeycomb is made using aluminum material with a thickness of 0.4 mm and then formed with varying hexagonal sizes, namely 2 mm, 4 mm and 6 mm. This compression test is carried out using a Universal Testing Machine with 2 positions, namely horizontal and vertical. The specimen is pressed until it finds a broken point that is visible on the graph. The results obtained from this compressive test are in the form of deformation values and the maximum force acting on the specimen. From the results of the comparison of hexagonal size variations, it can be concluded that the larger the size of the honeycomb hexagon, the greater the deformation that occurs

The honeycomb structure is a natural or man-made structure (material) that has a honeycomb geometry, which is aimed at lightweight construction material companies, also getting a quality level from the material selection. The purpose of this study was to analyze the energy absorption ability of the statistical pressure tester. Energy absorption is a method of how an object attenuates due to external pressure. The energy absorption test was carried out by means of a statistical press test, the test object made from aluminum plates in the form of a honeycomb structure with different hexagonal size variations. This section will compare the results of the stress-strain and energy absorption data on each tested specimen to see which one is more efficient among the three specimens with different hexagonal sizes.

Abstract

The pump is a device used to move fluid from one place to another through a media pipe or channel. The energy in the fluid is produced from the impeller which converts the kinetic energy (velocity) of the liquid into potential (dynamic) energy. Besides being used to move fluid (fluid) at this time the pump can also be used as a turbine by changing the working principle of the pump by giving a drop of water at an altitude to rotate the impeller on the pump so that the pump can operate upside down or called a pump as turbine), in this study the impeller on the pump as a turbine is driven by a water flow or water pressure that is large enough, the water flow is sourced from two centrifugal pumps with a series arrangement that functions as a driving force or fluid distributor which is assumed to be a high water fall or head. The use of centrifugal pumps with a series arrangement is so as to produce a large head to get a high water fall or a maximum head for turning a pump as a turbine. This study uses an experimental method that is using two centrifugal pumps as a fluid distributor and one pump that is used as a turbine and uses a variation of 5 watt and 10 watt light bulb. From the calculation of the suction pump and pump as a turbine without using a light bulb pump speed namely 920.5 rpm and the specific speed of the turbine produced is 76.61 rpm. by using a 5 watt light bulb load the pump rotation speed is 553 rpm and the specific turbine speed produced is 44.24 rpm, using a 10 watt light bulb load the pump rotation speed is 335 rpm and the specific turbine speed produced is 26.8 rpm. The greater the value of the pump head, the resulting water discharge will be smaller and vice versa, the size and size of the pump head obtained is also influenced by the presence of load on theturbine.
