Abstract

This study aimed to compare the influence of the hole diameter of the outlet of the main jet from 2.5 mm to 2.8 mm on the carburetor to the engine performance and fuel consumption.The test is performed with the brand gasoline motor honda tiger type GL 200 R  four-stroke single cylinder. The materials studied were the main jet. Tests performed with standard conditions in without making any changes. Testing machine at the ready on a dynamometers test bed. Then do the testing phase and retrieval of data that is torque and fuel consumption. Torque (Nm) play a modified jet yield increase of 2.2% from the main jet standard. Power (kW) jet modification produces a maximum power of around 2.2% of the main jet standard. The rate of fuel consumption (mf) on the main jet modification is greater than the main jet standard. Fuel consumption (sfc) on the main jet modification will further increase the standard of the main jet. Calorific fuel (Qi) in the main jet modification is greater than the main jet standard. Jet played modifications that do not significantly change the main jet standard.

Abstract

The tool pin rotational speed and welding speed affect the electrical conductivity value of the Al-Cu connection. Al-Cu connection is a butt joint resulting from the friction stir welding (FSW) process. The material used is Al 6061 and pure copper. The friction stir welding (FSW) process uses a pin tool with a pin design that integrates with the pin tool and a three-degree angle. The purpose of this study was to determine the electrical conductivity value of the Al-Cu connection with the friction stir welding (FSW) process at the butt joint connection. The variables used in this study were pin tool rotation speeds of 800, 1000, and 1250 RPM and welding speeds of 10, 12.5, and 16 mm/min. Tests conducted in this study were macro structure testing, measurement of resistance values,  and microhardness testing. Besides, an analysis of heat input and welding time is needed for each variable. The results of macro and XRD structure test results show that in the aluminum and copper connection, there are intermetallic compounds in the form of AlCu and Al2Cu. The results of the analysis state that the welding results with a welding speed of 12.5 mm/min are the most optimum variables. The welding process results in conductivity values ranging from 27.173 m?-1mm-2 and 28.09 m?-1mm-2. The presence of intermetallic compounds affects the conductivity value of the connection.

Abstract

Corrosion occurs in almost all metals. Even corrosion-resistant metals are corroded, but their corrosion rate is different from ordinary or non-corrosion resistant metals. This study examines the corrosion rate that occurs in stainless steel that is stainless steel. Stainless steel contains high enough chromium levels that can reduce the rate of corrosion that occurs. The metal material to be studied is the AISI 420 steel, which belongs to the Martensitic Stainless Steel class. This study examined the effect of heat treatment on corrosion rate and hardness level of AISI 420 steel. The heat treatment carried out was Quenching at 1020oC with a holding time of 60minutes with an oil cooling medium. After quenching the subsequent heat treatment is tempering with temperature variations of temperature 200oC and 300oC with a resistance time of 45 minutes and air cooling media. The results of this study showed that the base material specimens had the highest corrosion rate of 0.569 mm/y. The lowest corrosion rate is in specimens with quenching process with a value of 0.267 mm/y. The highest Vickers hardness values were found in specimens with quenching process with a value of 551 kg/mm2. The lowest hardness value is in the specimen with tempering process at 300oC with 405 kg/mm2.

Abstract

The growing trend today is the exclusive breast milk given to the baby until the baby has a sufficient age. This is certainly not too problematic for housewives who most of the time are at home, so it can menyusi baby without interference. But this is different from career women who have babies and want to provide exclusive breast milk, a great distance between home and workplace and time constraints become a barrier factor that makes exclusive breast milk becomes very difficult given career woman to her child. Cooler box can keep asi temperature remain in cold condition prevent damage of breast milk content. Inside the cooler box put ice gel to keep the temperature cool. The ice gel can keep the temperature cool for 3-4 hours. Another problem is the hygiene of the cooler box and storage container from the breast milk. Not infrequently the cooler box into a source of bacteria that can spread to the breast milk contained in the cooler box, this can be caused moisture or from the hands that are not sterile. This is because in the process of pumping and transfer into the cooler box is still using the manual by hand. The researcher will design a cooler box build by using thermoelectric as cooling from cooler box and have water sterilizer, which is useful to decrease the amount of bacteria by using uv light. Low levels of bacteria will make the cooler box becomes more hygienic as a storage area when it will be shipped.

Abstract

The purpose of this research is to know the effect of Fe12% powder alloy on aluminum to porosity and micro structure by gravity casting method. Metal Matrix Composite (MMC) is an engineering material formed from the combination of two or more materials to obtain new materials with better properties. Making of composite material with aluminum matrix or metal matrix composite (MMC) can be done by casting method. The composite forming elements are called boosters (fibers or particles) and binders (matrices). In the process of casting metal can occur porosity In the casting process with sand molds usually occur porosity, causing the mechanical properties of casting objects decreased. Porosity is caused by bubbles of gas, gas released by the core when exposed to metal liquid heat, resulting in pores or perforated defects.The process of smelting was carried out at the metal foundry laboratory of Mechanical Engineering UP 45 Yogyakarta. The smelting process uses a krusible furnace with coke fuel, on which it is placed kowi to place aluminum and iron powder to be melted. Aluminum and 12% iron powder are weighed in accordance with the volume of the pattern, so that the melt does not suffer from metal deficiency. Observation of porosity is done by looking visually on each side of the outer part of the casting object. Observation of microstructure using optical microscope is done by taking three samples of specimen castings that have been in the preparation of polishing machine and etching. The effect of Fe 12% alloys on porosity is the average porosity occurring on specimens A, B and C of 2,766 gr / cm3. The effect of Fe 12% alloys on micro structure is the spreading of Fe, Si and Mg elements evenly, but for the C specimens of Fe and Si bersenyawa, while the Al and Mg elements are separate.

Abstract

Kerupuk jengkol merupakan makanan tambahan sebagai pelengkap hidangan. Kerupuk jengkol banyak sekali penggemarnya dari kalangan anak-anak, muda dan orang tua. Hal ini disebabkan kerupuk jengkol itu renyah serta gurih dan dapat menyesuaikan jenis hidangan yang disantap. Disekitar kita banyak sekali tentang jenis kerupuk jengkol yaitu kerupuk jengkol yang berbentuk lingkaran. Hampir semua pembuat kerupuk jengkol, khususnya kalangan menengah kebawah dapat dikatakan sangat memerlukan sentuhan teknologi dalam pemotongan gendar kerupuk jengkol. Kebutuhan akan kerupuk jengkol oleh masyarakat semakin bertambah, sedang industri pembuat kerupuk jengkol belum dapat mengimbangi akan kebutuhan konsumen. Sampai sekarang industri kecil dalam hal proses pemotongan gendar kerupuk  jengkol masih manual, yaitu memakai pisau sehingga hasil yang didapatkan sedikit, tidak seragam dan waktu yang dibutuhkan lama dan proses pengadukan. Hal inilah yang menyebabkan kebutuhan akan kerupuk jengkol untuk dikonsumsi terbatas. Bagi industri kecil kesulitan tersebut diatas belum terpecahkan, sehingga diperlukan inovasi program pengembangan Teknologi, khususnya proses pemotongan gendar kerupuk jengkol. Tujuan utama dari kegiatan ini adalah membuat mesin pemotong gendar kerupuk jengkol dan mesin pengaduk yang mampu bekerja secara efektif, sehingga meringankan beban UKM. Metode yang ditawarkan: Survey, perancangan komponen, desain mesin, pembuatan, pengujian mesin, evaluasi, pembuatan laporan. Hasil yang didapatkan  mesin ini adalah 10 batang gendar kerupuk rambak seberat 5 kg proses pemotongan membutuhkan waktu 10 menit, karena proses pemotongan dengan menggunakan mesin. Dengan demikian hasil rekayasa dapat dikatakan dapat bekerja dengan baik, seperti yang diharapkan.
