Feeling disorder a group of clinical features characterized by reduced or lost emotional control and self-control. Affective disorders can be depression, manic or a mixture of both (bipolar). Someone who has mood disorders needs treatment as early as possible through early detection and an accurate assessment is carried out in consultation with a psychologist. So a system is needed that can detect the possible disturbance of the mood. Expert systems are part of artificial intelligence that mimics the slow pace of an expert. Bayes' Theorem is a way of knowing conditional probabilities. Conditional probability is the probability of an event occurring, given that it has some relationship with one or more other events. The probability value of symptoms and disease is obtained based on the experience of an expert. This expert system can produce a process of diagnosing mood disorders with some data about mood disorders in the form of symptom data, disease data and its probability value. The accuracy rate is 100% using 10 test data. An expert system for diagnosing mood disorders which is designed to be an Android-based application of JavaScript and PHP as a programming language, Cordova as a framework for creating mobile applications, PHP 7.2.1 as a web server, MySQL 5.0.21 as a database.

Planning and controlling costs and time is part of the overall construction project management. In addition to the assessment in terms of quality, the achievement of a project can also be assessed in terms of cost and time. The costs that have been incurred and the time spent in completing a job must be measured continuously for deviations from the plan. The presence of significant cost and time deviations indicates poor project management. With the existence of project performance indicators in terms of cost and time this allows preventive actions so that project implementation goes according to plan. The concept of "Earned Value" is one of the tools used in project management that integrates cost and time and by using Ms. Projects. Ms. Project is a project management software product and is developed and sold by Microsoft. It is designed to assist a project manager in developing plans, assigning resources and tasks, tracking progress, managing budgets and analyzing workloads. From the results of the evaluation of cost control and project schedules on outpatient and basement building construction projects using the earned value method, it can be concluded that the CV (Cost Variant) in this project results in 0 which means the Zero Number on the Cost Variant indicates that the cost is within the budget, SV (Schedule). Variant ) the value shows a negative number, this means that the completion of the work is delayed, the CPI (Cost Performance Index) is 1, meaning that the expenditure is in accordance with the project budget

Soft crab is an export product where foreign demand is much higher than production. In the production of soft crabs, it is done by keeping the crabs individually in a crab box which is placed in the pond until they molt. Molting is a natural process of molting, i.e. removing the old tough skin for growth purposes. Shortly after molting, the new crab shells are still very soft and will harden again after water absorption occurs. Therefore it is important to monitor molting crabs to help farmers in the cultivation of soft shell crabs. The number of crab datasets is 1060 which consists of 1000 training data and 60 testing data. There are several popular image classification algorithms, namely K-Nearest Neighbors (KNN), Support Vector Machine (SVM), and Random Forest Classifier (RFC). KNN, SVM, and RFC are classification algorithms from Machine Learning. This study aims to compare the performance of the three algorithms so that the performance of the three algorithms is known. Several parameters are used to configure the KNN, SVM, and RFC algorithms. From the results of the trials conducted, KNN has the best performance with 98.33% accuracy, 98.33% precision, 98.38% recall, and 98.38% F1 Score.

The socket is an electrical installation that functions as a liaison between electric current and electrical equipment, one example is a garden lamp. To be able to turn on, you need a power outlet, but manual sockets are considered less effective due to the development of human habits leaving the house with the lights still on. With current technological developments, namely utilizing internet of things (IoT) technology, a smart socket is made that can be controlled remotely via a smartphone. The smart socket is made using Wemos D1 R1 as the microcontroller and is equipped with a raindrop sensor as a safety where the system will turn off the electricity automatically when the sensor detects water and a notification will appear on the smartphone as if water has been detected, so users don't have to worry about leaving the house. with a state of forgetting not to turn off the garden lights.

The use of human labor in the industrial world in Indonesia is still very dominant, especially in Manual Material Handling (MMH) activities. The activity of bending and twisting in the workplace while doing MMH should be reduced or even if possible this activity should be eliminated because this attitude is prone to causing disorders of the musculoskeletal system. Considering that MMH activities have a vital role in the work carried out in the production process section, therefore the researcher will conduct an analysis of the Manual Material Handling (MMH) work posture using the Rapid Upper Limb Assessment (RULA). RULA is a work posture research method to investigate disorders of the upper limbs. The results of the work posture analysis based on the results of the assessment using the RULA method stated that all manual material handling activities assessed above required corrective action or efforts. In the shuttle area, the final score for the action category obtained is 7 with a high risk level and the action that must be taken is action now. In the Pirn Winder area, the final score for the action category obtained is 6 with a moderate risk level and the action that must be taken is action in the near future. In the vacuum heat setter area, the final score for the action category obtained is 7 with a high level of risk and the action that must be taken is action now.

Foil is a ship installed wings at bottom of hull support. If the speed’s ship increases, foil will produce a lift that causes the hull rised and exit from the water. Therefore, there will be a reduction in friction force that results in the ship's velocity increase. The choice of foil is important to improve the ship performance. The study aims to compare 2 optimization methods, namely Genetic Algorithm (GA) and Particle Swarm (PSO) produce maximum lift and minimum drag. The designed foil is Joukowsky type with angle of attack 2°, 4°, 6°, 8°, 10° and 150,000 Reynold numbers. The method is used to state initial geometry of Joukowsky foil, iterated JavaFoil, optimized by GA and PSO using GNU Octave software. They are compared foil produces the maximum optimum C L /C D value. Validation of lift coefficient (C L ) and drag (C D ) Airfoil S9000 is almost similiar with the Williamson experiment. Stall is at angle of attack 9.3 o , with C L error of 3.66%, C D error of 6.83%. It results in the allowed tolerances are below 9.5%. Validation with JavaFoil Solver shows accurate results, with error of 4.15%. GA optimization produces C L /C D averages of 41,777 so it grows 6,544%. Whereas the C L /C D average PSO is 36,197, improve of 4,793%. GA optimization has a fairly high convergence speed at the first, then followed by stagnation process, the resulted solution improves significantly.

If the speed’s ship increases, foil will produce a lift that causes the hull rised and exit from the water. Therefore, there will be a reduction in friction force that results in the ship's velocity increase. The choice of foil is important to improve the ship performance. The study aims to compare 2 optimization methods, namely Genetic Algorithm (GA) and Particle Swarm (PSO) produce maximum lift and minimum drag. The designed foil is Joukowsky type with angle of attack 2°, 4°, 6°, 8°, 10° and 150,000 Reynold numbers. The method is used to state initial geometry of Joukowsky foil, iterated JavaFoil, optimized by GA and PSO using GNU Octave software. They are compared foil produces the maximum optimum C L /C D value. Validation of lift coefficient (C L ) and drag (C D ) Airfoil S9000 is almost similiar with the Williamson experiment. Stall is at angle of attack 9.3 o , with C L error of 3.66%, C D error of 6.83%. It results in the allowed tolerances are below 9.5%. Validation with JavaFoil Solver shows accurate results, with error of 4.15%. GA optimization produces C L /C D averages of 41,777 so it grows 6,544%. Whereas the C L /C D average PSO is 36,197, improve of 4,793%. GA optimization has a fairly high convergence speed at the first, then followed by stagnation process, the resulted solution improves significantly. PSO is focused on local search so convergence is difficult to achieve. The recommended foil optimization is to use GA.
