Chicken is one type of poultry that has many benefits, so the chicken can be an option for livestock. This research was conducted to create an expert system that helps provide information to farmers about poultry diseases, especially broilers. This expert system is built on the Android platform and uses the Dempster Shafer calculation method to get the diagnosis of chicken disease. The data used in this study consisted of 38 symptoms and 10 diseases data which were limited to diseases caused by bacteria and viruses. Each symptom has the value of belief given by 3 veterinarians. This study used four types of testing in the form of black-box testing, questionnaire testing, theoretical testing, and accuracy testing. The results of the accuracy testing of the 30 cases given are 92.22% and the system accuracy is 93.33% if the system diagnosis results are assumed to be valid because it is a subsection of expert diagnosis. For questionnaire testing using the MOS, parameters obtained 4.58 results from a scale of 5, as well as theoretical calculation tests that get the same calculation results between the results of expert diagnoses and system diagnoses. Based on the test results, the system built is good and appropriate.

Rice (Oryza sativa) is one of the main commodities in Indonesia. One of the inhibitors of rice crop production is disease. Rice plant diseases can be caused by pathogens, host plants or bad environment. The process of diagnosing rice diseases requires expertise, knowledge and experience. This study aims to build an expert system that can diagnose 13 types of rice plant diseases from 43 symptoms based on the knowledge of 3 experts with forward chaining reasoning methods and mobile-based dempster shafer calculation methods. The testing technique used is black box testing, theoretical calculation testing, system accuracy testing and MOS (Mean Opinion Score) testing. The black box test results state that the expert system has 100% compatibility in terms of functionality. The theoretical calculation test results state that the expert system calculations are in accordance with the results of manual calculations. System accuracy testing results from 30 test cases get an accuracy of 81.11%. The results of MOS testing conducted on 30 respondents produced MOS of 4.2 from a scale of 5 categorized into a good system.

Software that contains defects (errors) can cause harm. Losses caused can affect all stakeholders. Losses can take the form of financial, time, and others. So before the software is implemented it needs to be tested. Testing on an application aims to check whether a program is running properly or not. In testing this software will use Blackbox Testing. Black Box Testing Method consists of several techniques, including Equivalence Partitions, Boundary Value Analysis, Sample Testing, and so on. Among the many testing techniques, in this study the testing technique was chosen using Equivalence Partitions. Equivalence Partitions technique is a test based on data input on each form in the performance data information application system, each menu input will be tested and grouped according to function whether it is valid or invalid. Testing is done on 4 forms that will be filled with data form added jobdesk, form added work targets, form edit work targets, form approve work targets, and employee performance while in the company. The test results show that there are still many shortcomings when validating data to be entered, so that it can cause data stored in the database to be incompatible with the expected data. The results of this test can be used as input to improve the application of performance data for the future.

Praktek Kerja Industri (PRAKERIN) information system is a system used to record grades and other student data relating to the implementation of work practices in industry. This information system must be error free. If an error occurs can cause losses to stakeholders. To provide assurance that the information system developed has been free from errors, it is necessary to test. Testing is one level of the program implementation process that must be passed in order that an error can be found. Tests that can be said to be good are if the tests were initially found no errors and then errors can be found, even if only a small error. In testing the Praktek Kerja Industri (PRAKERIN) information system it is proposed as a Black Box. Black Box testing has various techniques. Of the many testing methods currently available, the current testing will use the Boundary Value Analysis method. The technique of determining the limits that exist in the lower and upper values to be able to produce the actual value. The test results show that the information system developed has been error free and has good quality.

The train ticket booking application is an important application because it involves financial transactions. If something goes wrong can be detrimental to the parties involved. The developer of the train ticket booking application must be able to provide a guarantee that the application has been made according to the requirements and has good quality. To provide a guarantee can be done by testing the application. Testing on a product intends to check if a program has been running as per its capacities or still have blunders that should be adjusted so as to have a decent quality program. A famous testing strategy and broadly utilized by analyzers to investigate the program works out in a good way or not is Black Box Testing and White Box Testing. In this examination, the product that will be surveyed utilizing Black Box Testing is a train ticket booking framework that has two structures: the login structure and the booking type of the train pass to be filled by the administrator. The application will test utilizing Black Box Testing in which the test is just planned to see whether the program is as per the capacity that the program needs without realizing the program code utilized. The sort of testing of the Black Box Testing technique shifts one of which is Equivalence Partitions utilized by the creators in this investigation. Comparability Partitions procedure is a test dependent on entering information on each structure on the framework, each info menu will be tried and assembled by work either legitimate or invalid. Incorrect test results can be found and corrected immediately. So after testing, all requirements have been met and can be guaranteed that the train ticket booking application that has been made is error free and meets all the requirements specified.

In this paper, a novel positioner fixture with a high repeated positioning accuracy and a high stiffness is proposed and investigated. A high-precision end-toothed disc is used to achieve the high repeated positioning accuracy of the designed positioner fixture. The mathematical models of the cumulative error of the tooth pitch, the tooth alignment error and the error of the tooth profile half-angle of the end-toothed disc are analyzed. The allowable tolerance values of the cumulative error of the tooth pitch, the tooth alignment error and the error of the tooth profile half-angle of the end-toothed disc are given. According to the theoretical calculation results, a prototype positioner fixture is fabricated and its repeated positioning accuracy and stiffness are tested. The test results indicate that the stiffness of the proposed positioner fixture is 1050.5 N/μm, which is larger than the previous positioner fixtures of the same type. The repeated positioning accuracy of the proposed positioner fixture in the x, y and z directions are ± 0.48 μm, ± 0.45 μm and ± 0.49 μm, respectively, which is significantly higher than the previous positioner fixtures.

Testing is a process in implementing a program for the purpose of finding / looking for an error. A test case is said to be good is if the test to be performed has the possibility of finding an error that cannot be revealed. While testing is said to be successful if the test to be carried out successfully found an error that originally could not be found. This research was tested by applying the Black Boxt Testing method. There are several ways in the Black Box Testing method, namely Boundary Value Analysis, Comparison Testing, Sample Testing, Robustness Testing, Equivalence Partitioning and others. In this study using testing by Equivalence Partitioning. Equivalence Partitioning Analysis is a case / problem that will be tested by finding several errors and reducing / minimizing the number of cases that must be made. This test is performed on the Parking Management Application function to facilitate managing parking. The test results indicate the application is in accordance with needs.
