Abstract

One of the difficult material at the senior high school is the Reaction Rate, because students need to understand the factors that affect the Reaction Rate that are difficult if only explained verbally without being followed by practice. The problem is demonstrate the affect of the Reaction Rate requires time and effort. Learning books are considered to be lacking in representing factors of the reaction rate effectively. The teacher also has difficulty knowing the gap in understanding between students. Based on these problems, a learning media application is needed that can help teachers demonstrate the Reaction Rate material, know the level of understanding of students, are easily accessible and attract students' interest in learning. The methodology in this research uses Extreme Programming (XP) with the aim of covering all needs and changes in user needs. The design of the application is object oriented using the Model-View-Controller (MVC) design pattern.. The process of implementing the application is done using the CodeIgniter framework. Furthermore, the developed application was tested using the Basis-Path Testing and Compatibility Testing method to determine the level of successful implementation and User Acceptance Testing to determine user acceptance of the application. The results of the research indicate that the website-based Reaction Rate learning media application can accommodate needs and is easy to use by both teachers and students. Extreme Programming (XP) methodology is quite suitable to cover all needs, but for segmentation of learning media is less suitable because more changes occur in the user interface aspects.

Abstract

Aquarium water conditions that are not good can cause disruption to fish health, water conditions that tend to be unstable can interfere and threaten the health of fish. Ammonia gas that is dissolved in water exceeds a threshold that can be tolerated by koi fish can cause koi fish tend to be inactive in the aquarium due to food debris or feces from the fish. The mq-135 sensor is a device for detecting unpleasant odors in the air, which in this system is used to obtain the value of ammonia gas contained in the water content. Salinity or dissolved salt levels in aquarium water can also cause irritation to fish skin and people so that fish tend to rub against the bottom of the aquarium, but if the salt level is well maintained it can prevent, treat and kill bacteria that interfere with fish health, one of which is a bacterium caused by fish waste (ammonia). So that in this study a system was made that could classify the condition of the aquarium water by implementing the k-nearest neighbor method. The input of this system is the reading value of the ammonia gas sensor and electrical conductivity which will then compute and display the classification results on the LCD and the sensor reading value sent to the thingspeak platform. The results of this study obtained an accuracy of 27.28% for testing the k value and testing the time needed to do the computation so as to obtain classification results with an average of 1897.5ms or 1.9 seconds.

Abstract

Based on the export volume data recorded by the Ministry of Agriculture from 2012 to 2016, palm oil (Elaeis guineensis Jacq) became one of the centres of Government and investor attention. In the oil palm plantation company, one of which is PT. Sandabi Indah Lestari Bengkulu occurs constraints on palm oil crops that do not match the target expected. This target is the sum of harvest and when it is used to harvest the oil palm. When crops do not match the target, it can cause budgets of production that do not match the planned. Therefore, the company requires forecasting the crops to minimize the constraints caused by the crops that are not suitable for the target. The Multifactor High Order Fuzzy Time series method that is optimized with K-means Clustering to determine which subintervals are used can help in forecasting the oil palm harvest. The plot of this method is the determination of the Universe of discourse, the determination of the number of clusters, the formation of subintervals with K-means Clustering, the formation of the fuzzy set, the fuzzification process, the formation of Fuzzy Logic Relationship (FLR), and the defuzzification process. This research uses several factors that lacte over the harvest of oil palm Lot month, land area, age of the plant, and the amount of oil palm trees. From the results of the tested the sum of clusters, the sum of orders, the sum of training data, and the optimal threshold in the successive are 8, 6, 107, and 6 with the best AFER value of 36,98%.

Abstract

Meeting or consultation serves to bring two or more people to discuss together. Technology serves to facilitate access communication meetings and consultations are video conferencing. Video conferencing is communication using audio and video which connects users even though they are not in the same place and time. There is a service to share data or called file sharing when using video conferencing. Applications support video conferencing and file sharing is Skype, Cisco Webex, and Zoom. However, the above application has a disadvantage that each operating system is different and application installation is required for each different device. WebRTC is a solution to the problem. WebRTC can run on all browsers, open-source, and free. WebRTC uses JavaScript-based APIs to establish peer-to-peer connections. WebRTC requires two additional servers namely STUN and TURN to communicate peer-to-peer through NAT. Testing is to measure the reliability of file sharing to video conferencing. Testing is using six types of connections and three types of file sizes. First test result file sharing does not affect video conferencing because it runs on a different port. One Way Delay test results increase in line with the increase in the size of the file sent.
