Abstract

Yutuk, which is also known as undur - undur laut, is a typical souvenir from Widarapayung Wetan beach. The handling of yutuk before consumption by community groups processing yutuk is still in a simple way by soaking it in a bucket or tub. Depuration of yutuk or shellfish makes the dirt contained in the organs of the body come out and can reduce the heavy metal content contained therein. This Community Service activity aims to increase the education of yutuk processing groups to use the depuration method with a special yutuk tub with a recirculation system that uses natural filters such as ginger coral, zeolite and activated charcoal. The Community Service activity stage begins with interviews and field observations and then continues with a Focus Group Discussion (FGD) and then implements a yutuk depuration tub for the yutuk processing group in Widarapayung Wetan village. Through Community Service activity, the yutuk processing community groups are equipped with good and correct depuration techniques so that they can be achieved properly and the community can consume them safely and comfortably.

Abstract

Semi-automatic water purification machines are urgently needed by the people around the Sitopong river, Cilacap Regency. Required application and testing of the YF-S201 type water flow sensor based on Arduino Uno. This is done so that the application of the water speed sensor in the river water purification machine can be maximized. The research method used is a literature study related to Arduino Uno and conducting experiments. The experiments were carried out in the form of testing the water flow velocity sensor, carrying out the process of calibrating the water flow sensor. Sensor testing was carried out 10 times after calibration. Based on the calibration results, an average volume of 329 ml was obtained from the desired volume of 330 ml so that an error of 0.3% was obtained. Whereas at the desired volume of 600 ml, the average volume of the calibration results is 598 ml, it can be seen that an error of 0.3% is obtained at a volume of 600 ml. Function test on the water filling process with 10 trials obtained an accuracy of 99.6% for a 330 ml volume bottle and 99.6 ml for a 600 ml volume bottle.

Abstract

An analysis of the uncertainty value of measuring spur gear dimensions using a profile projector has been carried out. Dimensions of spur gears measured are pitch diameter, root diameter and outside diameter. The manufacture of 3 samples of spur gears was first made with a shape milling machine based on the initial technical data that had been determined. Then measurements were made with a profile projector measuring instrument for the three measuring dimensions, the best repeated measurement average was found in the root diameter measurement for the PJ01 sample of 32.4053 mm with a standard deviation of 0.0077 mm. The uncertainty method used is statistically and applies only to a series of observations. Determination of the uncertainty value is done by performing repeated measurements five times on the same sample. This method refers to ISO GUM with type A evaluation. The uncertainty value obtained for the best measurement is 0.0034 mm with an expanded uncertainty of 0.0068 mm with a 95% confidence level.
