Abstract
Bioethanol has a low calorific value from gasoline, so that in its application in the motorbike, the duration of fuel injection must be multiplied by natural air intake which results in a richer fuel mixture. Based on this problem, a research was conducted which focused on adding combustion air. This research was carried out experimentally on Honda CB150R engine with a compression ratio of 12.5 using 100% bioethanol fuel with modification of ignition timming and duration of fuel injection. The test was carried out by using 92 RON at a compression ratio of 12.5 which used 100% bioethanol fuel as a control group and a variation of adding combustion air using a blower. By taking 3 variations of the addition of air 10%, 20%, 30%. Tests are carried out using the Waterbrake Dynamometer at the opening of the full butterfly valve (Fully Open Throttle) to obtain maximum power at each engine speed and the desired engine speed setting is done by adjusting the load size. Each change in engine speed 2000 to 8000 rpm at intervals of every 1000 rpm. From the experimental results of adding combustion air with E100 bioethanol fuel at a compression ratio of 12.5, the best performance results were obtained in the addition of 10% combustion air. At the addition of air 10% torque, power, temperature and thermal efficiency produced increased by 12.52%, 9.25%, 12.52%, 35.18%, and Spesific Fuel Consumption (SFC) down by 29.15%.

Abstract
Lung is one of the vital respiratory organs in the human body. Where during respiration, there is a process of gas exchange in the lungs by taking oxygen (O2) from the air and releasing carbon dioxide (CO2) into the air. Because in the process of respiration involves air in the surrounding environment, the more contamination of air is inhaled, can cause various lung diseases. If the lung diagnosis is done early, then lung disease can get health care earlier. Chronic Obstructive Pulmonary Disease (COPD) is a type of disease that blocks the flow of air into the lungs due to swelling and mucus or phlegm, so that the sufferer has difficulty breathing. In making this research, we want to make a design tool to detect COPD and determine its severity using medspiro (medical spirometer). COPD can be diagnosed by measuring the value of Forced Expiratory Volume in One Second (FEV1), Forced Vital Capacity (FVC) and comparing it with predictive values of FVC and FEV1. The results obtained from the manufacture of spirometers have FVC measurement errors of 5.8950%, and FEV1 measurement errors of 10.5030%.

Published: July 2020

Abstract
Humans often encounter obstacles in doing their work. Especially if the work is related to an emergency situation that concerns the safety of human life, it needs quick and appropriate handling. Telerobotic technology that has a haptic function is one solution to these problems. In this study a system of 1 DOF haptic manipulator with slave master configuration was developed using bilateral haptic manipulator control. In bilateral control the position and information are transmitted in two directions between two manipulators. Position information is obtained using a potentiometer and force information is obtained by representing the force with the current using the WCS2702 sensor. There are three control methods used, namely bilateral symmetrical position control, bilateral reflection force control and force feedback bilateral control. The best method of control is the bilateral feedback force control. In the force feedback bilateral control system, the slave can move following the master movement with a ± 2° position error. When the slave arm is held by a hard object, the master arm is also restrained with ± 11° position error. Whereas when the slave arm is held by a soft object, the reflection of the object is felt by the master arm with ± 10 position error. Movement of the master and slave arms is lighter than using bilateral control of symmetrical position.

Published: July 2020

AbstractThe wound healing process consists of three phases, namely the inflammatory phase, proliferation, and maturation. An increase in the number of neutrophil cells and macrophages signifies an inflammatory phase. Fibroblasts and epithelialization indicate a proliferation phase, whereas in the maturation phase is marked by the occurrence of wound healing. Ginger (Zingiber officinale Roscoe) contains active substances, namely triterpenoids, flavonoids and saponins. Flavonoids function as anti-inflammatory. Although it has many benefits, the effect of giving ginger extract to neutrophil cells, fibroblasts, and epithelial thickness in incision wounds has not been studied. The purpose of this study was to determine the effect of ginger extract on the number of neutrophil, fibroblast cells, and epithelialization in incision wounds. The research design used was post test only control group design. Rats were divided into control groups given 1% CMC solvents and the treatment group were given oral ginger extract at a dose of 1 g / kg BW. The tissue was observed on days 1, 5 and 10. Based on the results of the Kruskall Wallis test, the p value was 0,000 with α 0,05, so it can be concluded that the administration of ginger (Zingiber officinale Roscoe) can reduce the number of neutrophil cells, increase the number of fibroblast cells, and increase epithelialization of incisional wounds in white mice (Rattus norvegicus).

Among other resources, anchovy becomes the prior Indonesia’s marine commodities greatly consumed by domestic residents and demanded by many exporters. Unfortunately, the production process of dried anchovy seemingly encounters several problems, especially in the drying process. Since the drying process uses sunlight, it comes into problems with a cloudy weather or rain. Less intensity of sunlight might make the drying process result not perfect dried anchovy. Moreover, current manual monitoring technique remains ineffective drying process. Thus, this study aims to design a prototype of automatic anchovy drying robot using Arduino ATmega 2560 microcontroller to address the problems. This study considers the uses of Arduino ATmega 2560 as a robot controller, DC motor as a driving system, and LDR and rain sensors as automatic modules. LDR sensors are used as a robot roof drive or anchovy drying container to open automatically when sunlight is detected. In addition, rain sensor serves to close the robot roof when it detects rains and the robot turns into its initial position. This robot is further expected to be able to work automatically and optimally in helping anchovy drying process.

Published: July 2020

Abstract
Partial discharge is a partial electrical discharge event in isolation that is not directly connected between the two conductors, which discharges can occur either near or not on the conductor. An Archimedean spiral antenna is created to detect partial discharges in high voltage equipment. Electromagnetic waves produced by partial discharge will be detected by the antenna which has a frequency range of 300 MHz - 3 GHz. The next measurement of partial discharge uses an RC detector. The purpose of this study was to determine the performance of Archimedean spiral antennas which were then compared to RC detectors. Based on the results of tests carried out as many as 50 times, both the spiral arsenic antenna or the RC detector showed good results. Antennas get slightly lower yields, due to the reduction in the flow of electromagnetic waves on the metal walls of high voltage equipment. Whereas RC detector is better by displaying more sensitive results.
