In the use of power plants that produce DC voltage, such as Solar panels (PLTS), Wind Power Plants (PLTB), Micro Hydro Power Plants (PLTMH), and others. Inverter is an important tool, inverter is a tool used to convert DC voltage into AC. The Modified Sine Wave Inverter is a type of inverter that produces a modified square wave. The design is done by connecting the inverter input to the battery and then connecting the jack to the inverter output so that the load being tested can be easily replaced with another output load, which is displayed by an oscilloscope of the form modified wave. The results of the research using this inverter produce the highest efficiency at an inductive load of 58.92% at a Blender load and the lowest efficiency of 1.67% at a 5 watt load.

Cow milking machines are used to help farmers in mountainous areas in the milking process. The problem faced is that it takes a schedule and selection of appropriate engine maintenance methods so that the milking machine for cows is not easily damaged. This study aims to make a schedule and determine the engine components that must be treated. The data obtained are then processed descriptively qualitatively. The results of the study concluded: (1) the maintenance of a portable milking machine with a bodypack model is carried out every day using the Inspection, Small Repair, Medium Repair, and Overhaul (ISMO) methods; (2) the main components to be examined are the electrical parts of the machine, the machine box, the putting straw, the milk container, and the carrying case; (3) routine maintenance carried out is proven to be able to maintain and extend the life of the portable milking machine model bodypack.

The applicaton of Performance Based Maintenance Contract (PBMC)is a kind of updated innovation which recently applied conventional contract. The maintenance contract performance based was applied by General Director of Highways (Bina Marga) to replace conventional maintenance contract. The contrast between conventional contract and PBMC lied on The maintenance system conducted. Conventional contract maintains the input and maintenance, however PBMC maintains the output and the outcome. The contractors independently determined the maintenance work will be conducted. In shake of fulfilling users intentions, the contractors will raise the value added for the maintenance process with fully creative and innovative. PBMC application training has been conducting since 2011 by director of highways, however the rapid overloading described that the condition of national roads application isn’t yet ideal, the provision of infrastructure is unstabel and preservation handling isn’t quite assertive and hasn’t completely conducted. In line with the well management principals, they are planning and organizing PMBC application. The way to handle broken and failed infrastructure. There are some topics being discussed in this paper, such as the deception of PBMC contract based on management principals, gap between field technically and basic concepts. Some challenges ruined over the concept of PBMC in improving the maintenance of national roads near future

Digestive disorders are various types of problems that occur in the body's digestive system, ranging from the mouth, esophagus, stomach, small intestine, large intestine, and anus. The digestive system functions to receive and digest food which is then converted into nutrients for the body to absorb. The absorbed nutrients will then be distributed throughout the body through the bloodstream. In addition, the digestive system is also tasked with separating and removing parts of food that are not needed and cannot be digested by the body. Digestive disorders that occur can be very difficult and should not be ignored. Many do not know that symptoms that are felt in the body are the result of certain digestive disorders, so it is often too late to be known and result in the need for a visit to the doctor. An Expert System is needed that can help the community in knowing the symptoms of the causes and prevention of digestive disorders in the body. Expert system to detect digestive disorders in this study uses backward chaining inference where the search process starts from the goal, which is the conclusion that becomes the solution to the problem at hand.

Kualitas menjadi faktor dasar keputusan konsumen di produk atau jasa. Akibatnya, kualitas merupakan faktor kunci yang membawa keberhasilan bisnis, pertumbuhan dan peningkatan posisi bersaing. CV Gunung Mas Medan merupakan perusahaan yang bergerak di bidang pembuatan keramik dengan sistem job order, dimana kualitas permukaan yang baik atau zero defect sangat diharapkan oleh konsumen. Pada keramik dengan motif White Ivory berukuran 40 x 40 cm yang diproduksi di Bagian II dengan pengambilan data yang dilakukan bulan Februari, Maret dan April pada tahun 2012 diperoleh rata-rata hasil produksi untuk KW 1 sebesar 67,83%, KW 2 sebesar 25,09% dan KW 3 sebesar 7,25%. Hal ini terjadi karena adanya proses yang kurang memenuhi spesifikasi yang telah ditentukan, sehingga output yang dihasilkan tidak konsisten dan memiliki tingkat variabilitas yang cukup tinggi. Oleh karena itu dalam penelitian ini masalah yang diangkat adalah bagaimana meningkatkan kualitas dengan menggunakan siklus DMAIC (Define, Measure, Analys, Improve and Control) dari Six Sigma. Dari penerapan metode tersebut didapatkan penurunan tingkat kegagalan yang cukup signifikan yaitu dari 57426,55 DPMO menjadi 40591,78 DPMO. Dengan perbaikan dan pengembangan sistem produksi yang telah ada masih memungkinkan dicapai nilai yang lebih baik lagi.
质量是消费者在产品或服务中做出决定的一个基本因素。因此，质量是导致企业成功、竞争增长和上升的关键因素。CV Mas Medan是一家专业从事陶瓷生产的企业，该公司采用了移位协议，其表面质量好或零缺陷都是消费者所期望的。2012年2月、3月和4月生产的白象牙图案陶瓷，平均输出为KW 1 67.83%， KW 2为2509%，KW 3为7.25%。这是因为缺乏既定的规范，产生的输出不一致，并且有相当高的可变性率。因此，在本研究中，所提出的问题是如何利用6 Sigma的DMAIC循环(定义、测量、分析、改进和控制)来提高质量。这种方法的应用大大降低了从57426.55 DPMO到40591.78。随着现有生产系统的改进和开发，仍然允许取得更好的成绩。
