Nowadays , most students are familiar with the notebook for daily use. The compactness and flexibility of the notebook offer more benefits than a PC. The teachers can engage it during teaching physics. Hence, th is research had developed an electrical circuit virtual experiment that acts like real experiments . It can be accessed easily by students in their notebook. This study introduces a flash-based animation C ircuit B uilder as a simulation designed to help students understand the electrical circuit. This study's purposes were: (1) to analyze the feasibility level of Circuit Builder for enhancing students’ electrical circuit mastery and (2) to know the effectiveness of Circuit Builder based on students’ electrical circuit mastery. Circuit Builder was developed by 4D (Define, Design, Develop, and Disseminate) model. The feasibility level was analyzed by CVI (Content Validity Index). Then, the effectiveness was tested with effect size . This study proved that the virtual laboratory "Circuit Builder” was feasible in physics class with a moderate effect size. The virtual laboratory could improve students’ electrical circuit mastery than doing practices with traditional laboratories .

Graph-QL (Query Language) is a new concept in the Application Programming Interface (API). Graph-QL was developed by Facebook which is implemented on the server-side. Although it is a query language, Graph-QL is not directly related to the database, in other words, Graph-QL is not limited to certain databases, either SQL or NoSQL. The position of Graph-QL is on the client and server-side that access an API. One of the objectives of developing this query language is to facilitate data communication between the backend and frontend / mobile applications. For this reason, this paper will examine the responsibility of Graph-QL in terms of response time and response size in the development of an integrated competency certification test system based on web service and compared with efficiency and flexibility using the REST API. From the test results, it was found that Graph-QL provided some advantages compare to REST API. It give more flexibility for the clients to access the data and solve the most typical problem that was over or under fetching cause by fixed data given by REST API endpoints.

Abstract— A variety of knowledge, especially for universities in making standards, is one of the important things to be managed and documented. The standard drafting process is carried out by the drafting team in holding meetings and meetings directly. Constraints arise when in the drafting process, the drafting team is difficult to determine the time of meeting the standard discussion directly due to busyness and work constraints. In addition, the unavailability of online media repositories for the PPEPP process is another obstacle because the standard documents that have been discussed are only printed and stored as campus files. This storage process is vulnerable to damage, loss, and sometimes it is difficult to do a search if it is merged with other documents. STMIK Multicom management system is not yet available that can accommodate these knowledge. Thus, to ensure the flexibility and changes of STMIK Multicom to keep up with technological developments, a system that can accommodate individual and organizational knowledge in one portal is needed so that the sharing process becomes easier. Through a systematic Knowledge Management System application development plan, the results of system testing conducted on respondents as system users obtained results of 81.16% as the value of benefits for the evaluation of KMS application planning.

Suhu dan kelembapan sangat berpengaruh terhadap keberhasilan tanaman padi. Untuk itu sangatlah penting untuk selalu dilakukan monitoring kedua aspek tersebut sehingga produksi tanaman padi dapat meningkat. Dan untuk melakukan monitoring diperlukan peralatan yang fleksibel, mudah dan murah dalam pengimplementasiannya. Oleh sebab itu dalam penelitian ini dibuatlah sebuah peralatan monitoring suhu dan pH yang berbasis embedded sistem dan wireless mesh. Penggunaan embedded system dikarekan bentuknya yang kecil namun power full untuk fungsi tertentu, dan wireless mesh memiliki fleksibilitas tinggi untuk diterapkan di area rurel seperti persawahan. Di dalam penelitian ini dilakukan dalam beberapa tahapan yakni studi literatur, analisa dan perancangan sensor berbasis embedded, pembuatan sistem, pengujian sistem dan diakhiri dengan pelaporan serta publikasi. Pada tahapan pengujian akan dilakukan di dua lokasi berbeda yakni di LAB Teknik Informatika dan di lokasi pertanian. Disamping itu parameter-parameter yang di analisa pada saat pengujian adalah stabilitas pembacaan suhu dan pH, pengaruh jarak jangkau wireless mesh terhadap kualitas pembacaan, pengaruh banyaknya hop dan pengaruh routing protokol wireless mesh. Setelah dilakukan pengujian dan analisa pada akhirnya akan didapatkan sebuah peralatan monitoring suhu dan pH yang handal, stabil, dengan karakteristik jarak, hop count serta routing protokol yang optimum. Penelitian ini akan memberikan manfaat yang besar bagi dunia pertanian oleh sebab itu sangatlah penting untuk dilakukan penelitian ini dan akan memberikan manfaat bagi masyarakat umum.

In several locations, the security system is becoming a priority. One of the location is the laboratory. There are many valuable research tools and equipment in the laboratory, so to improve the security system. Generally, the access to entry the laboratory is equipped with a digital safety system. Computer Control System Laboratory at Information Technology Department of Jember State Polytechnic uses RFID-Card as access right for entrance to the laboratory. RFID-Card also functions as ID-Card (printed with photo and biodata) and packaged to fit in user clothes pocket. However, using RFID gives less of flexibility. The user must remove the ID-Card and attach the card to the RFID reader box. Therefore, in this study will design a door lock security system based on the image processing to replace the use of RFID. Later, the user simply positions themselves in the Pi Camera work area. Processed data from the camera, the matched with image data which stored in the database. The database contains a photo of laboratory members which listed on the employee ID-Card. Template matching method is used as image matching method which stored in Raspberry Pi database. If the image which captured by camera is matched with the image data in the database, the controller will give entry access to the user. Based on the experimental results, template matching method has a success rate of 96%.

This purpose of this research is to identify and analyze the affect of environmental uncertainty on business performance, the affect of environmental uncertainty on strategic flexibility, and the affect of strategic flexibility to business performance. Strategic flexibility as a mediation variable. The design of this research is explanatory research. The research object are the Small Real Estate Developers (REDs) in the region of Probolinggo. The analysis uses is Partial Least Square (PLS). The results shows that there are influence between environmental uncertainty on business performance, environmental uncertainty on strategic flexibility, strategic flexibility to business performance, and strategic flexibility mediate environmental uncertainty on business performance. Nevertheless the mediating role of strategic flexibility in determining the magnitude of the influence of environmental uncertainty on business performance is smaller than the direct affect. Overall the results of this study indicate that if the uncertainty of the environment as a combination of� the state uncertainty, the effect uncertainty and� the response uncertainty can be used as a basis for Small Real Estate Developers (REDs) in forming strategic flexibility, then Small Real Estate Developers (REDs) will be able to improve its business performance Keywords: Environmental uncertainty, strategic flexibility, business performance, Small Real Estate Developers (REDs) �
