PENGARUH JARAK ANTAR FIN PADA SILINDER BERSIRIP TERHADAP SEPARASI ALIRAN DI PERMUKAAN SILINDER DAN FIN
Sudirman, -
Ruslim, -
AbstrakFluida yang mengalir melewati objek akan memberikan pengaruh yang cukup signifikan berupa gaya angkat dan gaya drag pada permukaannya. Besar gaya-gaya ini tergantung pada kecepatan aliran freestream, profil aliran, kondisi permukaan benda, bentuk maupun orientasi benda yang dilintasi. Pada bluff body, gaya drag didominasi oleh pressure drag sedangkan pada streamlined body, didominasi oleh skin friction drag. Efek viskositas memberikan kontribusi terhadap gesekan sehingga fluida pada boundarylayer kehilangan energi selama mengalir. Hal ini dapat menimbulkan separasi aliran di permukaan benda jika dikombinasikan dengan kenaikan tekanan. Semakin cepat separasi aliran terbentuk, maka luas daerah wake semakin besar. Pada penelitian ini, diamati silinder bersirip dengan variasi jarak antar fin untuk mengetahui pengaruh fin pitch tersebut terhadap separasi aliran di permukaan fin.Benda uji berupa silinder sirkular diameter 25 mm ditambahkan annular fin pada permukaannya dengan tebal fin 2 mm. Pengaruh jarak antar fin dengan variasi 10 mm, 14 mm, dan 18 mm terhadap separasi aliran di permukaan fin diamati dengan metode simulasi numerik menggunakan software Fluent 6.3 dengan bilangan Reynolds 2,5 x 104 berdasarkan diameter silinder dan kecepatan rata-rata inlet.Hasil pengamatan menunjukkan semakin rapat jarak antar fin, separasi aliran yang terjadi pada ruang antar fin terjadi lebih awal. Ketika jarak antar fin meningkat, posisi separasi aliran dan vorteks di permukaan fin bergerak mendekat ke daerah di belakang silinder. Hal ini menunjukkan bahwa udara tidak mengalir dengan baik pada daerah tersebut untuk fin pitch yang sempit.Kata Kunci: Silinder bersirip, separasi aliran, jarak antar fin.AbstractFluid flowing through the object will give a significant influence in the form of lift and drag force on the surface. The magnitude of these forces depends on the speed of the free-stream flow, flow profile, surface condition of the object, the shape or orientation of the object being traversed. In bluff body, drag force is dominated by pressure drag while in streamlined body, dominated by skin friction drag. The viscosity effect contributes to friction so that the fluid on the boundary layer loses energy during flow. This can cause flow separation on the surface of the object when combined with the increase in pressure. The faster the flow separation is formed, the larger the wake area. In this study, we observed finned cylinders with variations of the fin distance to determine the effect of the fin pitch on the flow separation at the fin surface.Test specimens of circular cylinder diameter 25 mm added annular fin on the surface with fin thickness 2 mm. The effect of fin distance between the variations of 10 mm, 14 mm, and 18 mm on the flow separation at the fin surface was observed by numerical simulation method using Fluent 6.3 software with Reynolds number 2.5 x 104 based on cylinder diameter and average speed of inlet. The observations show the closer the distance between fin, the separation of flow that occurs in the space between the fin occurs earlier. As the fin distance increases, the position of the flow separation and the vortex on the fin surface moves closer to the area behind the cylinder. This shows that air does not flow well in the area for a narrow fin pitch.Keywords: Finned cylinder, flow separation, spacing between fin.

Prasetia, Abdul Muis
Harto, Dedy
AbstrakMakalah ini menyajikan sistem pengaturan suhu dengan konverter AC-AC melalui metode fuzzy logic control, penggunaan konverter AC-AC dilatarbelakangi oleh banyaknya aplikasi pengaturan suhu menggunakan pemanas listrik dan umumnya menggunakan prinsip on-off. Karena keterbatasan range pengaturan tegangan yang dapat diberikan, maka kontrol tegangan secara on-off kurang dapat memberikan akurasi nilai keluaran yang dibutuhkan sistem, sehingga untuk beberapa aplikasinya dapat menimbulkan tanggapan sistem pengaturan temperatur yang kurang baik. Untuk meningkatkan kinerja pengaturan suhu dengan memperluas range pengaturan tegangan digunakan konverter AC-AC. Pada penelitian ini usulkan pengaturan konverter dengan metode fuzzy logic kontrol. Hasil pengujian menunjukkan bahwa konverter dapat berfungsi dengan baik dan respon dapat mengikuti setpoint. Fuzzy logic control menunjukkan Rise time sebesar 3 menit, serta ketika telah mencapai setpoint yaitu 30ºC, suhu sedikit berosilasi dengan error steady state 0%.Kata Kunci: Suhu, Fuzzy logic control, Konverter AC-ACAbstractThis paper presents temperature control system with AC-AC converter based on fuzzy logic control method, the selection of AC-AC converters is motivated by the many applications of temperature control system using electric heaters and generally using on-off principle. Due to the limited range voltage settings, then the on-off voltage control is less able to provide the accuracy of required output value of the system, so for some applications it can lead to bad temperature control system response. To improve the temperature performance by extending the range of voltage settings used AC-AC converter. In this research, propose the converter arrangement with fuzzy logic control method. The results show converter can function well and the response can follow setpoint. Fuzzy logic control shows 3 minutes rise time, when it reaches 30ºC set point the temperature is slightly oscillated with 0% steady state error.Keywords: Temperature, Fuzzy logic control, AC-AC converter.

Traffic Jam is a problem that often occurs in transportation problems. Juanda Junction is one of theintersections that often experience traffic jam. The causes of traffic jam arise from many things, includingthe presence of side barriers, the absence of markers so that the traffic light that works is not optimal.Based on the results of the initial survey, it was found that the duration of the green light in each pendekawas not adjusted for how many cars and motorcycles were passing. North approacher where most cars andmotorbikes are passing but get fewer duration of green lights than other approaches. This shows lessoptimal traffic light settings. The use of fuzzy method is expected to make traffic light settings moreoptimal because the old green light produced is more flexible in accordance with many cars andmotorcycles that pass through an approach. The results of the study were obtained for vehicles passingthrough the northern approacher as many as 26 cars and 177/cycle obtained manually by the green light for43 seconds and with fuzzy 45 seconds. Western approacher with many vehicles passing by 25 cars and170/cycle motorbikes received a 51-second manual green light and fuzzy 42 seconds. As well as for theeast approacher with many vehicles passing 24 cars and 168 motorcycles/cycle get the green lightmanually 53 seconds and with fuzzy 42 seconds. Key Words: Fuzzy, Junction, Traffic Light
Kemacetan merupakan permasalahan yang sering terjadi dalam masalah transportasi. Persimpangan Juandamerupakan salah satu persimpangan yang seringkali mengalami kemacetan. Adapun penyebab kemacetanmuncul dari banyak hal antara lain adanya hambatan samping, tidak terdapatnya marka hingga traffic lightyang bekerja kurang optimal. Berdasarkan dari hasil survey awal diketahui bahwa lama lampu hijau padamasing-masing pendekat tidak disesuaikan dengan berapa banyak mobil dan motor yang lewat. Pendekatutara di mana paling banyak mobil dan motor yang lewat akan tetapi mendapatkan lama lampu hijau yanglebih sedikit dibandingkan pendekat yang lain. Hal ini menunjukkan pengaturan traffic light yang kurangoptimal. Penggunaan metode fuzzy diharapkan dapat menajdikan pengaturan traffic light lebih optimalkarena lama lampu hijau yang dihasilkan lebih bersifat fleksibel sesuai dengan banyak mobil dan motoryang melewati suatu pendekat. Hasil dari penelitian diperoleh untuk kendaraan yang melewati pendekatutara sebanyak 26 mobil dan 177 persiklus diperoleh lama lampu hijau secara manual 43 detik dan denganfuzzy 45 detik. Pendekat barat dengan banyak kendaraan yang melewati sebanyak 25 mobil dan 170 motorpersiklus mendapat lama lampu hijau secara manual 51 detik dan dengan fuzzy 42 detik. Serta untukpendekat timur dengan banyak kendaraan yang melewati sebanyak 24 mobil dan 168 motor per siklusmendapat lama lampu hijau secara manual 53 detik dan dengan fuzzy 42 detik.

The rapid rate of growth of technology and information in the modern era today, encourages companies to further develop their thoughts and views to maximize the goals and objectives set. The Place to Practice Business Skills (TPKU), is a business engaged in the field of convection managed by Tebuireng Boarding School. One of the most widely used convection products is the school uniform. In producing school uniforms, convection also strives to continuously improve quality by pressing the number of defects in the product. Some things that need to be done are identifying the factors that cause disability using the Six Sigma method, calculate the quality of sigma, and propose appropriate actions to control the quality of school uniforms. Six sigma is a tool of quality improvement toward the 3,4 target of failure per a million opportunities for each production. So six sigma is one of the new methods in the field of quality management aimed at quality control and improvement. By using the six sigma method, it can be seen that there are seven types of defects (CTQ) that occur in school uniform products. The two most common types of defects are: seams that are not tidy with a percentage of 51.1% and stain on uniform of 28.4%. For the quality of school uniforms produced by Tebuireng Convection is still low ie 2.95 sigma with a product defect rate as much 74830 products in one million products (DPMO). From the application of these six sigma, it can be concluded that the proposed action to be done convection to reduce the level of product defects is to focus its supervision on improving employee performance, engine performance, applicable work standards, existing facilities and infrastructure, provide motivation to work, and improve time management well.

Coffee, Drying and Moisture
Coffee is one of the major agricultural commodities in Indonesia. The drying process is carried out conventionally (naturally), requires a relatively longer drying time between 1-2 weeks depending on the weather and hot sun, to shorten the time in the coffee bean drying process, a replacement heat source is needed, using a dryer with a roll tube type. which rotates using an LPG gas stove heater. The drying process uses drying variations of 60, 120, and 180 minutes with an initial weight of 1000 gr coffee beans with an initial moisture content of 22.8%. The drying process took 60 minutes, the weight of coffee beans was 955 gr, with 21% moisture content, temperature 42 ° C. Time 120 minutes, weight 911 gr with 20% moisture content, temperature 42 ° C, while time 180 minutes, weight yield 863 gr, water content 17%, with a temperature of 43.5 ° C. The greater the temperature in the drying process, the more effective it is to reduce the weight and moisture content of the coffee beans. The standard of coffee beans is 12% with a maximum drying temperature of 55 ° C.

Bambang Kurniawan, Basuki, Mochamad Arif Irfa`'i
Pipe bends, radius of turns and head loss.
The environment around us will not be far from the flow of fluids to meet the needs of life. For example, a series of PVC pipes used to distribute water at home, of course, has losses caused by its components, one of which is the pipe bend connection. One of the energy losses in changing the pipe cross section is the pressure loss. The pressure loss can be affected by the flow rate of the fluid and the magnitude of the bend connection of the pipe. The research in this thesis was carried out in the Mechanical Engineering laboratory of Hasyim Asy'ari University. This research is quantitative in nature which will discuss about the pressure loss in elbow pipe bends or broken and short pipe bends with a cross-sectional size of 1 terhadap inches to the value of pressure loss. The results showed that the greatest value of pressure loss was in the bend of the elbow or broken pipe, which was 0.002206 m, while the smallest value of pressure loss was in the bend of the short pipe which had a value of 0.00000332 m. So the conclusion of this pressure loss research is that the greater the r/d value of the pipe bend, the smaller the pressure loss value.

Analisa Hasil Penyusutan Kadar Air Temulawak Ditinjau Dari Waktu Pengeringan
Mochamad Chanifuddin Najib, Retno Eka Pramitasari
Drying, temperature, time, water content
Temulawak is a plant that is included in the category of plants that are very good for health. In its management, the community still uses natural methods such as solar heat, even though this method is less effective because the weather in Indonesia is uncertain. Therefore, there must be a new solution, one of which is to use oven drying. Oven drying is one method of drying using a temperature variation of 60°C with a time variation of 120 minutes. From the results of this study, the shrinkage value of the initial weight of the material was 400grams after the drying process was carried out, the final weight was 239.6 grams or the shrinkage was 40%. From this it can be concluded that the temperature and drying time are very influential for reducing the water content of temulawak.
