Tujuan dari penulisan Buku ini tidak lain adalah untuk membantu Mahasiswa dalam memahami MetodologiPenelitian. Buku ini juga memberikan informasi secara lengkap mengenai materi apa saja yang akan mereka pelajari yang berasal dari berbagai sumber terpercaya yang berguna sebagai tambahan wawasan. Walaupun buku ini memberikan ulasan teori secara ringkas Metodologi Penelitian, namun diharapkan dapat memberikan sumbangsih kepada Mahasiswa. Buku inimasih jauh dari sempurna. Oleh karena itu kritik dan saran yang membangun dari berbagai pihak sangat kami harapkan.

Nowaday, computers already can be used to provide choices in taking of the decision, not only used for data processing or presenting information, process of taking the decision it self is the results of a system that called Sistem Pendukung Keputusan (SPK). The system of taking the decision is possible because there has been a development of hardware technology, integration of hardware and software. In the business sector one of them is a truck and expedition which engages in the transportation services of stuffs between Lampung-Surabaya cities and vice versa. In this expedition service consists of arround used by 76 units of cars. And the supply of stuffs still used bookkeeping which is sometimes taking of the decision supply of stuffs is still handled by superiors. Therefore, this research used Simple Additive Weighting (SAW) method which is used to make decisions in problems solving by create a design system and building software. This research will create a system when taking the decision in the supply of stuffs in the Business Entity Expedition Services with SAW method by using WEB.

A game or game is something that can be played by having rules so that there is a winning and losing result, usually the game is a context that is not serious or for self-entertainment. Learning to recognize letters is one of the most important milestones in a child's development because it is the first step in learning to read and write. The game was made using the MIT App Inventor so that this game can be used on cellphones or smartphones, with the aim of this educational game not only for mere entertainment but with games we can also learn, so with educational games like this we can increase interest in learning. From the results obtained the conclusion is that this application can help respondents to learn to recognize letters. Based on the results of the recapitulation of the 5 test criteria that have been carried out, the results show that the number of answers from the respondents has a value of 100% according to the system functionality test using black box testing.

The development of the era towards the era of society 5.0, allows every human being in his life to using modern technology such as AI and robots to meet needs and make life easier. With technology, it will be easier, because all humans are aware that getting work done quickly and easily will be better. Technological development has advantages and disadvantages, but the weakness is that it will be a concern for every human being that in Society 5.0, machines will replace all human tasks easily and which can improve the quality of human life in general. Many problems arise in life, in the form of problems in the fields of education, culture, society, economy, and other issues. One of them is the problem of garbage or waste which is increasing at this time. Seeing this situation, we innovated to create the E-TRASH application, where the application In practice, allows the process of disposing of previously useless waste, to be converted into something that has economic value, namely money/balances. This study aims to create a design for the E-TRASH application system using an Android-based operating system, this is because the use of smartphones is growing rapidly. The design of the E-TRASH application system aims to facilitate the community in minimizing the use of waste in the surrounding environment. The design of this garbage bank program system will utilize a technology called E-TRASH which will later be used for a transaction system. This design process produces a UML design which will later be used as the basis for making which includes the design containing the menus in the application. The application of E-TRASH application uses smartphone technology for customers, namely the general public, the E-TRASH mobile application implements the M-BANKING system, in this application, customers can find out the balance of transactions made, not only obtain balance information, but customers can also see the total debit and credit when transacting, this application also implements a transfer system, where customers can transfer their money to other banks if they don't want to withdraw cash.
