Abstract

The thesis report for the April algorithm application of the menu sales in the TOCIN CORNER sukoharjo bar has been conducted on July 1, 2019-31, 2019. In view of the condition of sales in the TOCIN CORNER, there is still a problem in menu and raw materials stocks. Among other things, there is still a steady buildup of preordained menu supplies. This leads to the possibility of consumer disappointment even turning to other wedgies, as the availability of preferred menu has been exhausted. The objective of this thesis is to build a system that can be useful in locating and compiling the appropriate combination of the menu by using the apricot method on the menu sales in the TOCIN CORNER in order to increase the sales of the menu. The research methods used in this study include data collection methods and data analysis methods. Data collection methods include observation, interviews and library studies. While the data analysis method is done by means of data obtained will be described according to actual circumstances, researched, studied and processed as a material to create the program. In this study a design model system development life cycle (SDLC). The system development life cycle isa gradual approach to analyzing and building the design system using a specific cycle of user activities as for the SDLC stages are analysis, design, construction/coding, implementation, and testing. The results of the data analysis on the implementation of the menu selling system in TOCIN CORNER are using apricot method with system design usecase, output input design, database design, technology design, instructions to run the program. The implementation of the menu of TOCIN CORNER USES the apriestary method that has been created has transaction data facilities, daily data input, accounting processes, data reports. From this data the launch will produce results reports.

Abstract

The bottled consuming water enterprise has grown rapidly to diverse provinces and cities in the course of Indonesia now. The development of this enterprise is because of high call for clients and the lower nice of uncooked water in springs and wells PT. Cahaya Bumi Intanpari (CBI) is a agency that produces gallons, bottles, and glasses bottled drinking water beneath the logo “AirMu”. sales of bottled water every month constantly vary, the control of PT. Cahaya Bumi Intanpari calls for an estimate of the quantity of manufacturing of each type of bottled water to marketplace demand within the destiny. based totally at the description of the history, in this take a look at, a computing device-based application became designed and built. The research method used consists of information series and statistics analysis, statistics series includes remark, interviews, and literature have a look at, whilst statistics evaluation consists of making facts waft diagrams. The forecasting version is used in forecasting the income of bottled drinking water at PT. Cahaya Bumi Intanpari is a time series or it may be referred to as a time collection, and the forecasting technique used is unmarried exponential smoothing. From the outcomes of calculation checking out, it's far demonstrated that the single exponential smoothing method can be applied inside the AMDK income forecasting system, primarily based on the validity take alook at, it’s miles discovered that the prediction check effects of bottled consuming water sales below 20% are covered within the appropriate standards.

Abstract

Improvement of Human Resources (HR) is an effort made to form quality human beings with skills, work abilities and work loyalty to an organization or government. The flow of technology and information as well as the mobility of human resources from one place to another. One of the HR improvements that must be done is through training, education, and coaching. Information technology is a concept where certain objects have the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction. Sirnoboyo Village, Giriwoyo District, Wonogiri Regency. The purpose of raising the theme of improving human resources in the field of information technology for posyandu cadres and village officials is to provide insight and improvement on the basis for using Ms. Word and digital form creation with Google - Forms. The method of implementing the service includes a basic computer workshop using Microsoft Office 2013. Then a workshop on improving the ability of posyandu cadres in making digital forms using Google-Form. The resulting output is the implementation of a workshop and an increase in the capacity of Sirnoboyo village human resources, namely posyandu cadres and village officials. At the end of this program, activities will be published through print and online media. Keywords: Human Resources, Posyandu Cadres, Digital Forms.

Abstract

Intensitas hujan tahunan di daerah aliran sungai (DAS) Bengawan Solomengakibatkan debit aliran sungai besar di beberapa anak sungai. Debit aliransungai yang besar mengakibatkan tinggi muka air di beberapa pos pemantauanmeningkat. Tinggi muka air di setiap pos pemantauan diukur setiap hari denganperiode yang sama, pagi (06.00), siang (12.00), dan sore (18.00). oleh karena itu data tinggi muka air merupakan data runtun waktu. Salah satu metode peramalan data runtun waktu adalah single exponential smoothing dan Brown’s double exponential smoothing. Dalam penelitian ini akan dilakukan pemodelan data tinggi muka air sungai Bengawan Solo pada pos pemantauan Wonogiri Juni – Desember 2018.

Abstract

Along with the development of technology, some students have left learning with books because it is easier to find knowledge on the internet. But everything listed on the internet is abstract, and not all can be accessed by Android. Therefore an android application is needed to make it easier for students. The design of this android contains learning Mathematics, rules of enumeration and opportunities for multiple events for high school. This application uses data collection methods in the form of material from books, the internet, and various other sources. Development methods include system analysis, system design and system testing. The design of this application uses Adobe Flash to make applications and Android as compailer. The programming language used is action script 3.0.

Abstract

Bioinformatics is a science that studies the management and analysis of biological information. Bioinformatics includes application of mathematics, statistics, and informatics to biological problems to solve. Bioinformatics can store data generated by the genome project with regular and high degree of accuracy. Basic local alignment search is one of the methods used to process penyejajaran molecular data sequences. In 2009, there is a virus that attacks the respiratory tract that is the swine flu. The virus is spread around the world, so that retrieved the journal research on diverse virus DNA sequences in different endemic countries. Therefore, in this study will be explained about the process sequence alignment of the H1N1 swine flu virus. H1N1 Weiss AF 250365.2 and H1N1 Swine AF250364.2 have 90% similarity level.
