<![CDATA[Peanut washers are useful for cleaning soil that sticks and can speed up the washing process inpeanut production. Peanut washers on the market have a fairly expensive price for small andmedium businesses so that it becomes a hindrance to have a peanut washing machine for smallentrepreneurs because it requires peanut washers at a cheap price by modifying used clotheswashing machines. In the modification of peanut skin washers to determine the optimalcleanliness of the use of the optimal number of brush variations from the results of washingpeanuts, use a GUI with image processing techniques looking for normalization of RGB valuesin Matlab Software. From image processing using RGB normalization value on matlab with freevariables using variations in the number of brushes 1, 2, and 3 pcs and 1 kg peanut-fixedvariables and 40 liters of water for 10 minutes to get the optimal use of 1 brush in experiment 2using 1 brush of 60% or 6 clean beans of 10 samples rather than 2 brushes and 3 brushesbecause on 2 and 3 brushes many nuts are stuck by the handle of the brush resulting from thevolume of water parallel to the brush angle so that it is not brushed.]]>

<![CDATA[Cooling is the best preservation method than others because the food that has been cooled will remain fresh and will not experience a change in taste, color and aroma, besides all the activities that cause decay will stop so that the cooled food will last longer. (Hartanto, 1984). With the proper cooling engine planning, it can help with spatial adjustments, adjustments to loading, estimation of the power to be used, and budget plans. That is what is commonly called the cooling load calculation. Calculation of cooling load needs to be carried out before planning. This is necessary because the magnitude of the pending load is very influential on the selection of the cooling engine so that the freezing point for preserving food can be accurate. Pendiginan burden is influenced by external and internal factors. With the experimental method, it is obtained the results of the external cooling load as the external cooling load is 11.6 kW, the inner cooling load is 138.8 kW and the performance work coefficient (COP) is 2.]]>

<![CDATA[Carburizing is a heat treatment process with the addition of carbon content to the metal surface. To obtain the microstructure and the desired properties of the metal can be obtained through the heating and cooling process at a certain temperature. To get a high hardness value after the carburization process of the workpiece, the quenching process is carried out, namely the rapid cooling process, so that the martensitic phase is obtained. AISI 4140 steel is one type of steel that is widely used in engine components such as piston pins. The piston pin is usually made of medium carbon steel AISI 4140. Based on its application this steel was developed with the aim of having mechanical properties especially hardness, strength and resistance to wear. This study tested the hardness of AISI 4140 steel before and after the solid carburizing process using 80% bamboo charcoal as carbon and 20% Barium Carbonate as a catalyst, with a holding time of 60, 90, and 120 minutes using oil quenching media. The results obtained showed an increase in the highest hardness value at the holding time of 120 minutes.]]>

<![CDATA[Surface roughness of a product plays an important role, especially for materials such as SUS 304 steel which is now widely used in a variety of industrial needs. Determination of the turning parameters or the appropriate type of cooling fluids are very important to obtain the desired surface roughness. The aim of the study was to determine the ideal value of feeding (f) and the ideal type of cooling fluids in the turning process of SUS 304 steel. The feedrate parameters used were 0.11 mm/rev, 0.15 mm/rev, and 0.19 mm/rev, whereas the types of cooling fluids used are Fumio Lube Fumicool 794 soluble oil and Suncut 16S lubricant oil. Surface roughness results are obtained through testing using a surface roughness measuring instrument. From the predetermined parameters were obtained the smallest roughness value on the feedrate was 0.11 mm/rev using Suncut 16S lubricant oil with a result of 0.770 µm, while the largest roughness value on the feedrate was 0.19 mm/rev using Fumio Lube Fumicool 794 soluble oil with a result of 3.942µm.]]>

<![CDATA[Baja mempunyai peranan yang sangat penting dalam bidang industri maupun otomotif, sebagian besar bahan utamanya terbuat dari baja. Contohnya seperti roda gigi, roda gigi termasuk kedalam golongan baja karbon rendah. Baja ini dapat ditingkatkan lagi kekerasannya dengan cara dilakukan proses perlakuan panas dengan metode karburasi. Karburasi ialah proses penambahan unsur karbon yang tujuannya untuk menambah kandungan karbon agar bisa ditingkatkan lagi kekerasannya di area permukaan baja. Agar mendapatkan struktur mikro dan sifat baja yang diinginkan pada logam tersebut, dapat diperoleh melalui temperatur pada fasa austenite yang kemudian di dinginkan dengan pendinginan cepat sehingga dapat menghasilkan fasa martensite. Baja ST37 mempunyai karakteristik mudah dibentuk, ketangguhan dan keuletannya yang tinggi tetapi mempunyai kekerasannya yang rendah. Tujuan penelitian ini adalah untuk mengetahui nilai kekerasan baja ST37 sebelum dan sesudah proses karburasi padat yang menggunakan media arang batok kelapa sebagai penambah unsur karbon dan barium karbonat sebagai katalis, dengan waktu pemanasan masing-masing yaitu 850°C, 880°C, dan 930°C yang kemudian di quenching dengan media oli. Dan hasil kekerasan baja maksimum dicapai pada temperatur 930°C.]]>

<![CDATA[Enhancement human need for energy, especially fossil energy that is used in everyday life as fuel in industry and fuel that is used for personal use. Increased consumption of fossil fuels is not offset by the availability of natural resources, therefore alternative energy is needed to reduce dependence on fossil fuels. One alternative energy that has been found is electrolysis of water to produce HHO gas. This study aims to determine the production rate and efficiency of the HHO gas generator using a variety of NaOH, NaCl and KOH catalysts where each catalyst uses a mass fraction percentage of 4.76%. From the results of the research that has been done the results of NaOH catalyst have a flow rate of 2.203 ml / s and are the best catalyst compared to 1.24 ml / s NaCl catalyst and 1.859 ml / s KOH catalyst. Then for efficiency, KOH catalyst was obtained as the best catalyst with an efficiency of 8.76% compared with NaCl of 8.18% and NaOH of 7.82%]]>
