    Bread is a type of snack that with times becoming a primary food on daily life. In the process of making bread, beside the composition of materials, there is a step that conclude whether the dough is ready for baking or not, which called Proofing. In this proofing process, the temperature and humidity will be controlled according to the required proofing standard. The trouble is to control the stable temperature at 35°C and 80% RH humidity when the proofing is being process so we can have the perfect dough before we start with the baking process. For this research, a machine was made to help the proofing process where the temperature and humidity can be controlled with using Fuzzy-Pid method to an oven so we can make the dough expand perfectly. To display the temperature and humidity inside the oven, the machine equipped with LCD Temperature Display with censor DHT22. Based on the research, we acquired a respectable result where the fastest time to reach the set point of 35°C and humidity 80% RH is 8 minutes. Room temperature 29.3°C and room humidity is 69%RH.

    Sistem Kontrol Dan Monitoring Load Bank 150 Kw Berbasis Android
    (Politeknik Negeri Batam, 2017-05-18) Dolly Harahap, Syukri; Febriansyah Juwito, Arif
    By using automation technology, everyone can do anything without act direct manually. With the convenience offered, the human need for automation applications will always increase. One of The example is control of load bank. Load bank is needed in the commissioning process of medium voltage generating system. The manual operation of load bank is considered inefficient because it is ineffective in time and communication, which slows down the work. Control and monitoring of load bank based on Android is felt to be able to solve the problem. By using a smartphone we can control and observe the power loading system in one time. To apply on the load bank, it require a system which can communicate and perform commands remotely. Remote method can determine which execution will be done through android smartphone. In testing of load bank, control is done at different distances, The distance between the user and the load bank affects the decision-making speed of the device. The response is proper and accurate, the speed of the load transfer process occurs for 1,0 seconds from a distance of 50 meters, and 1.42 seconds from a maximum distance of 100 meters. The largest drop in voltage occurs at load 45 kW in amount of 3.25%.

    Kipas Otomatis Menggunakan Fuzzy Logic
    (Politeknik Negeri Batam, 2017-05-16) Andhika Fernanda, Dio; Juwito, Arif; Ridwan, Ridwan
    Fan is an electronic device which has function to produce wind. In general, fan still using manual system that need push button provided by manufacturer. By controlling fan using this manual system, it requires the operator to change speed of the fan. Therefore it is necessary to control the speed of the fan automatically. The automatic control used microcontroller with fuzzy logic method. By utilizing this method, we can adjust condition of the fan according to the value of two temperature sensors that will become fuzzy logic input. The result are obtained when the input fuzzy temperature 1 equals 30,74oC and temperature 2 equals 29,77oC, then output fuzzy it in the range 0-100% is 72.30% the result is mapped into PWM as input dimmer circuit. Then the PWM determined the speed of fan, and within 10 minutes if the PIR sensor did not detect any movement the fan will turned off until it detect any movement again.

    Rancang Bangun Configurable Lambda Sensor Controller Pada Oxygen Detection System
    (Politeknik Negeri Batam, 2017-05-16) Adhiyatma Tp, Yoga; Pamungkas, Daniel
    Oxygen detection system is a system which is capable to detect presence of oxygen in one place. One kind of the sensor used in an oxygen detection system is lambda sensor. This sensor only operate effectively at temperature 300°C to 750°C . So, it needs lambda controller on its application. Problem arise when controllers in market only has one kind of output for specific application. That way, a configurable controller would facilitate user to comply for many system. To resolve this problem, writer designed a configurable lambda sensor controller. This controller designed with some selection of output, that is 4-20 mA, 0-10 V, and a relay output. The presence of this device is expected to ease user in installation of lambda sensor, especially for instrumentation needs.

    Ic Tester Menggunakan Mikrokontroler Arduino Dengan I2c Module Sebagai Output Ke Lcd 2x16
    (Politeknik Negeri Batam, 2017-05-24) Rusnadi; Sugandi, Dr Budi
    IC or Integrated Circuit is one of the important electronic components in an electronic device. IC is divided into two categories, Digital IC and Analog IC or Linier. Linier IC is used for amplifier, voltage regulator and radio frequency receiver, while digital IC is used as flip-flop, logic gate and et cetera. In this last assignment, a development in an IC Tester was made by using micro single board. This IC Tester using method compared output and truth table.The purpose is to check the condition of logic gates in an IC. This device will give information about location of a broken gate and the IC’s category if the recognition code is missing. The test result will be compared manually. The obtained results show this device can work well with level of accuracy 100% (one hundred percent).

    Pengendali Tinggi Torch Plasma Cutting otomatis Pada Motor Penggerak Pnc-10
    (Politeknik Negeri Batam, 2018-01-19) Ismail, Muhammad; Istardi, Didi; Pamungkas, Nurman
    In the cutting system by the method of plasma cutting, the distance of torch to cut material greatly affect the success of cutting material. This research aims to make the control of high torch motor drive, with controller input coming from the output voltage of plasma cutting machine of Hyperterm Powermax85 which has been reduced by 50 times the actual plasma output value of plasma machine during cutting process. The problem limitation of the manufacture of this tool is that it controls only one driving motor with one axis, up and down. In this study, the measurement of output voltage is done by using digital clamp meter and digital multimeter while to measure the distance of torch by using filler gauge and caliper. Then, the tool has been made, tested the functionality of the tool by adjusting the position of the workpiece by reviewing the kerf value changes. Based on the measurement of torch distance to material from 0mm to 8mm distance, the material condition is cut off and when the distance is 9mm, the material condition is not cut. Thus found the limit of the distance torch so that the material can be cut that is equal to 8mm. Then by taking large data of plasma output voltage which has been divide 50 times by voltage divider on plasma machine cutting to torch distance to cutting material, each of 0mm, 2mm, 4mm, 6mm, and 8mm, obtained data of average voltage of 2,620 V, 2,755 V, 2,995 V, 3,185 V, and 3,243 V. So based on the data, there is a relationship between the change of voltage (plasma output) to the distance (torch to cut material) that is: V = 0.083 (Distance) + constant. This equation shows that there is a relationship between the distance and the near linear voltage. While with cutting test of material set at different distance with fixed cutting machine position, this tool can cut the material without any part of the material that is not cut with the change of kerf value of 0.4mm from the initial value of 2.7 mm.

    Pengontrolan Oksigen Terlarut Pada Tangki Pengangkutan Ikan Menggunakan Logika Fuzzy
    (Politeknik Negeri Batam, 2017-05-15) Ariswandi; Ridwan, Ridwan; Wivanius, Nadhrah
    Controlled transport tanks for live fish are important things that are needed by the distibutor to keep the fish alive and fresh to the destination. Therefore, need a system that can control and maintain dissolved oxygen stability (Dissolved Oxygen) in water in fish transport tanks. A closed tank transport system requires pure oxygen for the survival of the fish in it. This parameter (oxygen levels) can be used as input obtained from Dissolved Oxygen sensor input to create a control system using fuzzy logic method, where fuzzy logic will compare the error and deltaerror value, so that the output oxygen can be adjusted to the requirement. The end result of this control system research shows that the transportation tank has been able to maintain the stability of dissolved oxygen in water according to the fish consumption requirement that is set with the 7.5% error rate.
