Abstract

Program PKM ini bertujuan untuk meningkatkan kualitas dan kuantitas produksi sambal di Dusun Leses Kabupaten Malang. Sambal merupakan salah satu unsur khas hidangan Indonesia. Ada bermacam-macam variasi sambal yang berasal dari berbagai daerah. Masyarakat kota Malang yang didominasi remaja dan mahasiswa baik dalam kota maupun luar kota Malang rata-rata menyukai makanan dengan citarasa pedas atau menggunakan sambal. Permintaan pasar akan sambal kemasan di kawasan ini semakin meningkat. Lokasi mitra Dapur Uni Amel berada di RT 04 / RW 09 Dusun Leses, Kelurahan Ngijo, Kecamatan Karangploso, Kabupaten Malang. UKM Dapur Uni Amel yang dimiliki oleh Ibu Darnety ini telah berproduksi sejak tahun 2017. Mitra UKM telah berusaha untuk mengembangkan produksinya dengan menambah varian jenis sambal. Hingga saat ini ada 5 macam varian rasa yang berhasil diproduksi yaitu: Sambal hijau, Sambal merah, Sambal bawang, Sambal teri dan Sambal pencit.  Beberapa kendala utama yang dapat diungkapkan disini adalah kurangnya modal pembuatan produksi sambal, sehingga produksi dilakukan dengan skala kecil yang menyebabkan cash flow tidak terjadi dengan baik. Proses produksi pada mitra masih menggunakan alat-alat masak yang sederhana dan masih manual menggunakan cobek, yang tentunya kesulitan jika pesanan yang masuk banyak. Ada beberapa tahap dalam proses produk pembuatan sambal, dikarenakan ada beberapa varian rasa dan tiap varian sambal memiliki proses yang berbeda. Penyelesaian masalah yang dialami mitra melalui pelatihan peningkatan kualitas sistem pengelolaan keuangan UKM, pelatihan manajemen organisasi, pengadaan alat produksi yaitu mesin sealer plastik dan mesin penggiling sambal.

Abstract

The study aims to determine the effect of using a mixture of methanol add on to pertalite to the performance of gasoline engines, especially injection system with a capacity of 250 cc engine with two cylinders. This research used experimental method with variables used in this research is mixture of pure pertalite (P), mixture of pertalite - methanol 90% - 10% (PM1), mixture of pertalite - methanol 80% - 20% (PM2), mixture of pertalite - methanol 70% - 30% (PM3), mixed pertalite - methanol 60% - 40% (PM4), 50% - 50% (PM5) pertalite - methanol mixtures, pertalite - methanol 40% - 60% (PM6). Variable related in this research is power, torque and working temperature of the engine. The results of this study indicate that the addition of methanol with pertalite fuel tends to produce lower power and torque, while the temperature of the radiator and exhaust system shows that the use of methanol mixture with pertalite fuel can significantly increase the engine temperature of the vehicle.

Abstract

In a power plant unit whose main fuel is coal, there is generally use a belt conveyor installation. This conveyor belt serves to supply coal from the crusher unit to the combustion chamber of the power generation unit. In this study, we discuss a case where the installation of a belt conveyor which was initially only one line was then made a new branch that supplies coal to other power generating units. Equitable capacity distribution and continuity of coal distribution are the main focus of this study. Therefore, a design of automatic control system of coal flow divider on belt conveyor installation was designed. The working principle of this coal flow splitting system is to control the movement of the straight blade plough that directs the flow of coal to each unit at the certain time and continuously. Straight blade plough in the form of steel metal plate with a thickness of about 10 millimeters in which one end is connected to the end of the pneumatic cylinder. Automatic control system of coal flow divider in belt conveyor installation designed using CX-Programmer and CX-Designer applications. CX-Programmer serves to create automatic control logic concepts. While the CX-designer functions to create a Human Machine Interface (HMI), making it easier for operators to control the course of the coal supply process. The results of this study are in the form of control logic lines that can be applied to Programmable Logic Control (PLC) device and Human Machine Interface (HMI) equipment.

Abstract

Almost of kids in the world still bring a lunch box and a bottle of water in their bag when their go to school. His mother always prepares a lunch box complete with a bottle of drinking water, hoping that his son can enjoy his favorite lunch and avoid starvation. Sometimes the mother is very worried when the lunch box has been brought by the child but the water bottle is left behind. Then the mother was willing to take her child's water bottle to her school. This is certainly not expected by either the mother or the child. As a form of concern for the author to this problem, the author proposes a lunch box design with a lunch box lid that also functions as a drinking water bottle. The idea of this design proposal is ones grab, both are food & drink in your hand. The goal is how to make a kids can grab their food and drink easily and practice. So it is proposed to modify a top cover of common foodpack to become a drink bag. The design process begins with analyzing market needs, making sketches, creating 3D design models using the Autodesk Inventor CAD application, material selection, and product evaluation.

Abstract

This research proposes a new model of overlap and helix blade shape. The overlap shape of the blades gives room to the air flow shortly after pounding the blades. Air flow direction is strived to be able to push the next blade so that the process of the turbine blade rotation becomes more effective. While the helix model is expected to produce a more efficient turbine rotation due to its multilevel shape. The wind speeds tested were 2 m / s, 4 m / s, and 6 m / s. Turbine speed rotation data retrieval is carried out at each additional time. The overlap blade has a greater angular velocity value of 9.4 rad / s at 2 m / s wind speed, 21.9 rad / s at 4 m / s wind speed, and 29.8 rad / s at 6 m / s wind speed.Turbines with multilevel helix blades have a higher level of stability compared to overlap blades. This is because there are two levels of turbine blades which have an angle difference of 600 which can receive more stable wind collisions. However, due to the smaller cross-sectional area of the helix blade turbine (ie 50% of the overlap blade) the effective impact area on the blade is also getting smaller. So that the energy that can be converted is also relatively smaller than the overlapping blade.

Abstract

Two-phase flows consisting of liquids and gases are often found in everyday life and are used on an industrial scale. In an industrial environment, this flow has many weaknesses, including pressure drop and void fraction. One strategy to reduce losses that arise is to use passive methods. The passive method used is to utilize the shape of the grooves in the channel. In this study, the flow is used to determine its effect on the pressure drop and void fraction that appears in two-phase flow. The experimental method was used for this study. The test pipe is equipped with 16 grooves, while the smooth pipe (without grooves) is used as a comparison. The test pipe is made of acrylic material. The water fluid is circulated using a centrifugal water pump with a superficial speed of 0.33-0.42 m/s. Air fluid is supplied using a compressor with superficial speeds of 0.049, 0.066, and 0.082 m/s. Measurement of pressure drop was carried out using a pressure transmitter with an Arduino data logger. The void fraction is calculated by determining the ratio of the volume fraction of water and air in the test tube. The results of the study revealed that the use of 16 grooves in the pipe can reduce the pressure drop and cavity fraction that appears when compared to smooth pipes.
