Abstract

Knowledge of SOPs, documents, regulations, and experience is not well documented in the SEAMEO BIOTROP SLID environment to support the process of disseminating knowledge (knowledge) between employees in the SEAMEO BIOTROP SLID environment. Personnel experience and knowledge are lost when personnel are replaced, transferred, retired, or have expired personnel. At present, knowledge and experience in daily work accumulates in each personnel and is not documented in documents and systems, so it depends on each personnel. This research uses a methodology developed by Fernandez and Sabherwal. The results of this study are at the forefront of developing the knowledge management process. The knowledge management process developed at SLID SEAMEO BIOTROP is externalization, internalization, outreach for knowledge sharing, direction, routine, combination, socialization for discovery and knowledge sharing. Features created by a knowledge management system to support the knowledge management process consist of document management, knowledge management, discussion forums, and search capabilities. The prototype knowledge management system has been tested by SLID SEAMEO BIOTROP personnel using the user acceptance testing method and overall results are included in the evaluation criteria very well at the level of 84.51%.

Abstract

Fajar Collection is an individual business store that sells various products such as school uniforms, Muslim clothing, and casual clothes. In the existing business processes at Fajar Collection, using social media in the process of online sales transactions using Facebook and WhatsApp. However, with the online transaction business process, there are several obstacles experienced by the Fajar Collection store, namely, it is difficult for customers to find out stock availability, because there is no stock availability information on Facebook and WhatsApp, so customers have to ask the sales staff about stock inventory. Another obstacle is that the product promotion process is less than optimal, causing old products to be sold and slow to get new potential customers. Another obstacle is difficult in processing sales report data, because it is still done in bookkeeping by looking at sales notes to be included in the sales report, thus allowing different recordings of sales numbers and less than optimal in knowing sales data. Based on these constraints, an e-commerce website was designed using the Business Model Canvas (BMC) approach. Analysis of the strengths and weaknesses of the e-commerce business using the BMC methodology. The system was developed using the Unified Modeling Language (UML) approach and a Content Management System (CMS) based website with WordPress using the woocommerce plugin. Then it is optimized by applying Search Engine Optimization (SEO) so that the site is on the first page of search engines, making it easier for customers to find the site. With the E-Commerce website, it will expand product sales promotions, and help customers who want to buy directly from the website. It is hoped that by utilizing this E-Commerce website, it will be easier for customers to process the purchase transactions in Fajar Collection.

Abstract

Construction of oil and gas product storage facilities is one of the oil and gas activities in the downstream sector. A common impact on the environment from oil and gas activities is in the form of pollution of land, water, or air, it is necessary to identify the level of vulnerability to pollution early, areas that are sensitive to pollution are the main concern. The results of the initial identification of the level of vulnerability to pollution are shown in the map of the level of vulnerability to pollution processed using a geographic information system using the method of interpolation, weighting, and overlapping. The results of the initial identification of the level of vulnerability to pollution at the location of the oil and gas product storage facilities are divided into 3 (three) classes of vulnerability levels, low, medium, and high. The study area is in a relatively medium to high level of vulnerability with a high level of vulnerability being near the sea, so it needs high attention in its management.

Abstract

Solar cells or photovoltaic is a renewable energy source as a generator of electrical energy that is able to convert solar energy into electrical energy. Solar cells consist of series and parallel arrangement to form a solar panel. Solar panel technology is widely used, one of which is space technology, especially satellite technology. Solar cells use in satellites generates energy required for the satellite operation. To design the arrangement of solar cells based on the expected power and or the power produced, one of them is using mathematical modeling methods; The mathematical model of solar panels is developed and presented in this paper using the Matlab-Simulink GUI application. This mathematical model was developed using the basic circuit equations of a solar cell including the effects of solar irradiance and temperature changes. Based on the modeling, the output characteristic curve of the model is obtained according to the characteristics of each solar panel of the equatorial low orbit communication satellite. The power generated by the solar panel will increase when the solar irradiance increases at a constant temperature. When the temperature decreases and the solar irradiance remains constant, the output power and voltage increase slightly while the output current approaches a constant.

Abstract

Leasing the lab room is one of the services provided by the Integrated ICT LAB for every citizen of the Budiluhur University campus. So far in the process of borrowing the computer laboratory, the borrower must come directly to the Integrated ICT LAB or use social networks such as WhatsApp to communicate in two directions in making loans lab. This is not effective enough to serve borrowers who are usually lecturers. In the process of borrowing the lab, there are many problems, for example, the collision between lecture schedule and lecturer activity units, student activity units and other activities that require laboratory facilities. Seeing this problem, an application is needed to facilitate lab borrowing and coordination to the mobile-based ICT LAB Assistant. Meanwhile, for integration with existing systems a web service is required as a backend system so that lab lending services can be accessed by various platforms. The architecture used in the web service uses the RESTFUL API (Application Programming Interface), but there are still some problems with the RESTFUL API, namely regarding security in the process of authentication and data encryption on borrower data. In the REST architecture, a security method is needed, namely using the JSON Web Token and the Advanced Encryption Standard-256 (AES-256) cryptographic method. On the Web Services client side that provides requests and receives responses from the server then a token will be generated for the user which becomes plain data to be encrypted then saved to the database, and pulls the cipher data to be decrypted and returned to the calling application so that it can make transactions between platforms
