Abstract

IEEE 802.15.4 is one of the standards of the Wireless Sensor Network (WSN) which is at the Medium Access Control (MAC) layer. IEEE 802.15.4 is also technology and protocol within a computer network that can connect all device quickly, has a large capacity and low power consumption. The challenge of Wireless Sensor Network is how to improve the Wireless Sensor Network network performance matrix (goodput, bandwidth utilization, and energy consumption) both in the Contention Access Period (CAP) and in the Contention Free Period (CFP) based on the IEEE 802.15.4 standard. This research is an analysis combination of adjustment delay and slot duration methods to increase goodput, bandwidth utilization and reduce energy consumption in Wireless Sensor Networks in the allocation guaranteed  time slots on fixed data simulated using Castalia Simulator software. The problem of this research is whether the combination method can improve the performance matrix of Wireless Sensor Networks on fixed data compared to other methods (SUDAS, ADES, IEEE 802.15.4 Standard). This reserch it aims to determine the performance matrix of combination methods is when compared to other methods (Superframe Duration Adjustment Scheme (SUDAS), Adjustment Delay Scheme (ADES), IEEE 802.15.4 standard) using quantitative approach research methods. Based on the data obtained, the goodput of the combined method increased by 10%, 416%, and 513% respectively compared to the SUDAS method, ADES method, and IEEE 802.15.4 standards. Bandwidth utilization of the combination methods increased by 0.025, 0.223 and 0.232, respectively compared to the SUDAS method, the ADES method, and the IEEE 802.15.4 standard. And the consumption of the combination methods are respectively reduced by 1.02%, 8.72% and 9.08% compared to the SUDAS, ADES and IEEE 802.15.4 standards. With the combination method of delay adjustment and slot duration it is able to optimize the performance of the Wireless Sensor Network compared to other methods.

Abstract

Learning in school or in every educational institution has an important role as a media liaison between knowledge and students or students. There are many learning methods or models used in education. Of the many methods or modes, there is one of them is a clarification value technology (VCT) model. The teaching method is a knowledge of teaching methods used by a teacher or instructor. Another understanding is the presentation technique mastered by the teacher to teach or present learning materials to students in class both individually and in groups. the learning method by clarifying the value of the value clarification technique is teaching to shape students in finding and determining a value that is considered good in dealing with a problem through the process of analyzing existing values and embedded in students. Meanwhile, learning outcomes are abilities students have after they have a learning experience. The purpose of this study is to determine the level of learning outcomes of a particular institution. In this study the object of research from an educational institution that is competent in the field of flight is used. The institution is Surabaya Aviation Polytechnic. The subject of learning taken was Regulation of Dangerous Goods at Surabaya Aviation Polytechnic. In addition, this study was also conducted to determine differences in learning outcomes of cadets in the Lessons on Dangerous Goods Regulations in Surabaya Aviation using the Value Clarification Technique (VCT) method. This type of research is Classroom Action Research (CAR). The research carried out is included in the design of one group pretest and possttest research. the research design that contained pretest before being given treatment and posttest after being treated. This research was conducted at Surabaya Aviation Polytechnic. The data analysis technique used is the different test. Based on data management and analysis results, it can be concluded that the application of learning of Value Clarification Techniques can improve the learning outcomes of cadets. This is evidenced by the differences in learning outcomes of Cycle I and Cycle II significantly
