    (Simposium Nasional Rekayasa Aplikasi Perancangan dan Industri (RAPI) XII 2013, Fakultas Teknik Universitas Muhamaddiyah Surakarta, 2013-12-05) Iriani, Yani; Mariana, Adjeng; Lestari, Sri; Murnawan
    Informasi pemasaran merupakan titik tolak dasar untuk menyusun strategi. Keterbatasan informasi tersebut dapat mempengaruhi kualitas strategi pemasaran, baik strategi pasar produk, strategi bauran pemasaran (strategi-strategi produk, harga, distribusi, dan promosi), maupun strategi keunggulan bersaing, yang pada gilirannya dapat mempengaruhi daya saing industri. Hambatan suatu industri dalam meraih daya saing dapat mengancam kontinuitas usaha. Implikasi dampak selanjutnya akan mengancam industri kecil dalam kemampuannya untuk mengemban misi menciptakan nilai tambah dan kesempatan kerja di dalam negeri serta menjadi salah satu basic dalam pengentasan kemiskinan. Salah satu strategi pemasaran yang dapat digunakan oleh perusahaan adalah pemasaran berbasis website. Namun kenyataan di lapangan, banyak implementasi dari system pemasaran ini gagal disebabkan bukan karena faktor teknis namun lebih pada faktor sumberdaya manusia. Penelitian ini akan mengkaji perilaku pengguna sistem informasi di sebuah institusi lembaga pendidikan dan pelatihan di kota Bandung berdasarkan faktor-faktor yang mempengaruhinya dengan pendekatan Technology Acceptance Model (TAM). Adapun tujuan penelitian ini adalah untuk mengetahui pengaruh Perceived Ease of Use (PEOU) terhadap Perceived Usefulness (PU), 2) Mengetahui pengaruh Perceived Ease of Use (PEOU) dan Perceived Usefulness (PU) terhadap Attitude Toward Using (ATU), 3) Mengetahui pengaruh Perceived Usefulness (PU) dan Attitude Toward Using (ATU) terhadap Behavioral Intention to Use (ITU), dan 4) Mengetahui pengaruh Behavioral Intention to Use (ITU) terhadap Actual System Usage (ASU).

    ANALYSIS OF ENTERPRISE ARCHITECTURE MODELS USING PERFORMANCE QUANTITATIVE ANALYSIS TECHNIQUE
    (De la Salle Lipa Philipines + Universitas Widyatama Bandung, 2011-04-27) Murnawan; Sumiati, Ros
    To create such an integrated perspective of enterprise architecture, we need both a description technique for architectural models and model-based analysis techniques to realize this global optimization in practice. However, the value of architecture models increases significantly if they can also be used to support the decision making process. In this paper we argue that whenever a change in the enterprise architecture is needed, model-based analysis plays a central role.This paper presents an approach for quantitative analysis of layered, service-based enterprise architecture models, which consists of two phases a top-down propagation of workload parameters and a bottom-up propagation of performance or cost measures. By means of an example we demonstrate the application of the approach, and show that a seamless integration with other performance analysis methods.

    Business intelligence is a system that can help an executive or a decision-maker to analyze a fact that can become a value from a profit or sales from a different dimension. Business intelligence provides a data visualization usually in a form of graphics or charts that can help the decision-maker to make a decision. It can also help to do trend analysis and help make an indicator when the business is off the track. It can help the decision making a process like for item positioning and customer segmentation. The creation of a business intelligence dashboard can help PT. Inisiatif Mitra Mandiri to do the extensive analysis in order to make a decision such as sales performance monitoring, item positioning, and monitoring, and customer segmentation dashboard. Sales performance monitoring means that they can monitor the sales performance of a company and helping the executive to realize when their sales performance is off the track and need to be fixed. It gives a trend analysis about the sales and can help the executive to detect the losses. While item monitoring can be used to monitor the item in each site that is having high demand and can be used to plan for a placing and stocking the items on that site. For instance, executives can manage to make planning for item stocking on each site by looking to the previous years on which items are getting high demand. For customer segmentation, it can be used to determine a profitable customer that needs to be retained and it needs customer data from various dimensions that can help them to do the customer segmentation.

    (Solid State Technology Volume: 63 Issue: 3, 2020) Iskandar, Defina; Darmawan, Galih Rizka; Puspitasari, Nindya; Darajaat, Raafi’ud; Murnawan
    This study aims to design a data warehouse used to present operational information related to purchase prices, price increases, purchase values for parts, currency, and vendor performance evaluation at PT. XYZ, especially in the purchasing department. The problem is the difficulty obtaining the desired data because of the large amount of operational data that must be processed and combined from several sources. When the purchasing department has to decide which vendor to use for purchasing raw materials, it must look at data from each vendor, which takes a long time. The process of designing a data warehouse is done using top-down. The top-down method is a method where a series of processes begins by analyzing the problems that exist in the company. The data warehouse architecture that will be used is a centralized data warehouse. This architecture contains a collection of several separate sources and is put together into one centralized place. The data collected will be distributed into their respective functions for further use by the divisions—certain according to need. With the design of this data warehouse, it is hoped that PT. XYZ, especially the purchasing department, can easily get operational information needs without looking at data from several sources.

Information is a very valuable commodity in this era of globalization to be mastered in order to improve the competitiveness of an organization an ongoing basis. To answer these challenges, the Government of the Republic of Indonesia has initiated a policy for the use of ICT to build the Electronic Government for Good Governance is integrated from the local level up to the center. The aim is that the ICT infrastructure to be built can be used together to coordinate by all agencies, both at central and regional levels. The main indicators of their e-Gov are the services to the public and interaction between government agencies, as well as the interaction between government agencies and non-governmental, complete through online channels. That is, it can be said there are e-Gov if people still have to leave the house to take care of licensing, taxes, public school enrollment, certification of property, etc. Implementation of e-Gov development may not be comprehensive from the outset but will continue to grow steadily over time, in tune with the readiness of each layer of bureaucracy that would be expropriated e-Gov and socialization to people. But the reference and direction must be right in order to reach the goal, that no manual service to the public, both individuals and institutions, and there is no manual interaction among institutions, and there should be no redundancy process and data. Development e-Gov in XYZ City, still require the appropriate references to Reach Goal and Objectives with due regard to the development needs at every layer of bureaucracy, so we need a Master Plan E-Gov XYZ City that can accommodate the needs of the implementation of government services to the public and interaction with other agencies or other agencies online, according to the dynamics of development in XYZ.

    AN IMPLEMENTATION OF FUZZY LOGIC TO SALINITY CONTROL OF CHANOS CHANOS POND BASED ON INTERNET OF THINGS
    (International Journal of Psychosocial Rehabilitation, Vol. 24, Issue 1, 2020) Indra, Jamaludin; Fauzi, Ahmad; Murnawan
    Chanos chanos has great potential to become a business field in Indonesia. To manage a farm many factors must be considered, one of the factors that must be managed well is Water Salinity. At present in Tanjungpakis - Karawang Village, pond farmers still use traditional methods to find out the condition of pond water. Farmers do it by looking at the color of water, the smell of water and using taste buds. Generally brackish chanos chanos can grow well in water conditions that have saline levels ranging from 5 - 25 ppt. With changing environmental conditions and weather, the salinity of ponds usually increases or decreases, during the dry season the pond water salinity usually increases quite dramatically, whereas in the rainy season the pond's water salinity is usually at normal or even less normal limits. Farmers in the pond do additional fresh water in the dry season and increase sea water in the rainy season so that the pond's water salinity remains stable. this study made a water salinity control system for chanos chanos fishponds. The control system is carried out by measuring the salinity of pond water using conductivity sensors, processing data using fuzzy logic, direct monitoring through computers and mobile phones and using aquaculture, namely freshwater and sea water pumps to maintain the stability of salt levels in the ponds. This system runs well with an accuracy rate of 87.8% compared to refractor meter and condition determination using fuzzy logic with 100% accuracy.

    (International Journal of Psychosocial Rehabilitation, Vol.24, Issue 01, 2020) Malabay; Augustinus, Andreas; Tjahjono, Budi; Murnawan
    Cost estimation is a part that will be used as a basis for determining whether a construction project is feasible or not, the estimated cost is also required at the beginning before the start of a project. Cost estimation has an important role for the parties involved in it such as the Project owner, Consultant Planner and contractor. In general, construction cost estimates are divided into conceptual cost estimates and detailed cost estimates. Conceptual cost estimation is the estimated cost based on the concept or general description of the building to be built, for example a modest house, a luxury home, and. Through this estimation, conceptual costs are obtained, namely costs based on a general description that becomes a reference to the planned building construction before the detailed costs are calculated. Detailed cost estimation is the estimated cost based on a detailed calculation of the quantity and unit cost of each building component so that a more accurate total cost is obtained. The data used in this study came from the Indonesian Association of Appraisers (MAPPI) and the Ministry of Public Works and Homework which have been reviewed and used in the professional world.
