Abstract

The check-out system is one of the most important systems when we make purchases at a shopping center, shops, supermarkets, or mini markets. Determining different types of fruit is one of the problems faced in making payments, especially in supermarkets, because cashiers must determine the category labeling and weight of a particular fruit to determine the price. In this research, a design is proposed which utilizes Deep Learning in the field of image processing using the Convolutional Neural Network (CNN) algorithm utilizing RaspberryPi3. In making a classification system that uses deep learning, there are several main process stages, such as dataset collection, system design, training, and testing to see the results of the designed CNN model. The processed dataset in this research is a fruit image dataset derived from the Fruits-360. The results of the learning process obtained CNN models with 100% accuracy and loss of ≤ 0.026. The results of the CNN model that has been carried out will be combined with the load cell sensor which is expected to be used as an automatic self-checkout, especially for fruits. On the other hand, the calibration process of the loadcell weight measurement sensor is conducted which resulting an error measurement rate of 0.2 grams.

Abstract

Practicum is one of the supporting activities in the learning process as well as routine and mandatory activities that students must follow. Practicum management at the Untirta Industrial Engineering Laboratory is still carried out conventionally, so it is inflexible, inefficient, and the information provided is not detailed and transparent. The design of information systems in practicum management is carried out to overcome these problems. This study aims to obtain a practicum management information system design at the Untirta Industrial Engineering Laboratory. The method used in this study is the Framework for the Applications of System Thinking (FAST) method. The results of this study indicate that the practicum management information system design at the Untirta Industrial Engineering Laboratory is in the form of a context diagram that describes the process and scope of the system. Data flow diagrams provide an overview of data flow in processes within the system and entity relationship diagrams describe the relationships that exist in entities. Blackbox testing has been carried out on 17 page groups and shows valid results and functions properly. The usability test resulted in a system usability scale value of 86.75 which indicates that the designed information system is acceptable with grade B and an excellent rating.

Abstract

Waste water needs to be managed properly based on its characteristics to reduce the levels of contaminants contained therein. Communal IPAL or Waste Water Treatment Plants (WWTP) is a centralized wastewater treatment system. Several Communal WWTPs in Bone Bolango Regency have been built, but monitoring is rarely carried out. The purpose of this research was to determine the processing efficiency of communal WWTPs in Kabila District (Dutohe Barat Village and Tanggilingo Village), and Tilongkabila District (Butu Village and Iloheluma Village). The parameters measured were Total Suspended Solid (TSS), Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Coliform, Ammonia, and fatty oil tests from inlet and outlet water samples from WWTP. The values obtained are then compared with the quality standards based on the Indonesian National Standard (SNI) 6989.59:2008 concerning Water and Wastewater. The research method uses non-experimental with a quantitative descriptive approach. Sampling using a purposive sampling technique. Based on the results of observations, it was found that there were differences in the results of the efficiency of domestic wastewater treatment, namely the highest TSS removal efficiency in Butu Village (82.9); total coliform in all locations (0); the highest removal in efficiency values were in Iloheluma Village, namely BOD (100), Ammonia (86.95), COD (65.53) and fatty oil efficiency values (98.11) in Tanggilingo Village.

Abstract

In competing with competitors, each company will certainly do various ways so that the performance of its employees can be maintained properly, one of which is to provide rewards and punishments. This research was conducted by the authors to be able to show the effect of reward and punishment on employee performance at PT. XYZ in Karawang because at the time the research was carried out the reward and punishment system that was currently implemented by PT. XYZ was still not optimal. Because all members of the population consisting of 16 people were sampled in the study, the sample for this study was a saturated sample. Multiple linear regression is the method used for problem solving in this study. The results showed that after testing with multiple linear regression methods each (partial) there was no effect on each independent variable, be it reward or punishment on the dependent variable on employee performance at PT. XYZ. The researcher's suggestion for the company is to make improvements to the reward and punishment so that it can be used as a tool to improve the performance of each employee.

Abstract

Indonesia is the largest coconut fiber producing country in the world and has not been able to process it optimally. Egg shell waste is also one of the wastes that is often encountered because many food raw materials use eggs. This research was conducted to determine the value of the compressive strength of concrete with the addition of coconut fiber ash and eggshell powder as a substitute for cement and which of the percentages of 0%, 0.5%, and 1.5% added mixture has optimal compressive strength for concrete quality. K – 225 or equivalent to 19.3 MPa at 28 days of age. The method used in this study is an experimental method according to SNI 03-2834-2000 concerning Procedures for Making Plans for Normal Concrete Mixture. The results of this study revealed that the addition of coconut fiber ash and eggshell powder to the concrete mixture decreased the compressive strength compared to normal concrete but not significantly. The average compressive strength value of normal concrete is 19.58 MPa. Whereas the compressive strength of concrete with the highest added material is the percentage of 0.5% coconut fiber ash and 0.5% eggshell powder with an average compressive strength of 19.30 MPa.
