LEMIGAS merupakan lembaga pemerintahan yang bergerak sebagai badan penelitian dan pengembangan yang berfokus pada sektor teknologi minyak dan gas bumi milik kementerian energi dan sumber daya mineral. Saat ini penerapan SI/TI di lingkungan LEMIGAS belum optimal mengacu kepada sistem yang belum terintegrasi sehingga pertukaran data dan informasi tidak efektif, investasi SI/TI yang dilakukan juga belum memberi return yang baik, proses pengadaan setiap tahunnya secara konsisten tidak optimal, dan beberapa indikator kinerja ditemukan tidak memenuhi targetnya. Oleh sebab itu, diperlukan adanya perencanaan enterprise architecture pada LEMIGAS yang bertujuan untuk merumuskan prinsip dan dasar-dasar LEMIGAS agar sesuai dengan arah tujuannya sehingga menghasilkan proses bisnis yang sehat, sistem yang dapat mendukung kegiatan operasional serta infrastruktur yang mampu menunjang sistem tersebut dapat berjalan baik. Perencanaan enterprise architecture ini dibuat menggunakan TOGAF (The Open Group of Architecture Framework) versi 9.1 dengan metode ADM (Architecture Development Method). Perencanaan enterprise architecture ini akan menghasilkan diantaranya peta kegiatan utama dan pendukung LEMIGAS, stakeholder, fokusnya, tujuan bisnisnya dan prinsip dasarnya, blueprint target arsitektur bisnis, arsitektur sistem informasi, arsitektur teknologi, analisis gap, serta roadmap implementasi aplikasi.
Eguards are newly established startups that provide on-demand online security. It's still difficult to be able to develop the potential of existing resources and trying to improve customer brand awareness. Therefore, research being conducted on digital strategy planning. This digital strategy planning uses the Design Thinking approach supported by an analysis of the Platform Design Toolkit. This digital strategy planning focuses on analyzing platforms from the customer side of Eguards. The data collection method is carried out through literature study, observation, and interviews conducted at Eguards startup and Eguards user questionnaire. The results of this research are in the form of three suggested features that researchers propose in this research which are intended to increase the ease of Eguards application users, namely the "chat -on apps" feature, the feature can see the coverage of the Eguards service area and the feature of adding payment methods.
PT. Jakarta Maju Pusaka adalah perusahaan yang bergerak dalam bidang kargo barang yang sangat berperan dalam pertumbuhan ekonomi, terutama dalam bidang ekspor-impor barang di Indonesia. Selama ini manager dalam melakukan monitoring finance perusahaan masih menggunakan proses pencatatan pada buku besar di bagian finance. Sistem informasi monitoring (dashboard system) mempunyai ide dasar dan manfaat yang dapat diperoleh sama dengan analogi kegunaan dashboard bagi pengemudi, yaitu dashboard dengan layar yang didesain yang menampilkan informasi mengenai kondisi bagian finance, yang memungkinkan para eksekutif dapat dengan cepat mengidentifikasi masalah dan menentukan langkah perbaikan untuk meningkatkan kinerja pada bagian finance PT. Jakarta Maju Pusaka secara keseluruhan. Pembangunan sistem informasi monitoring (dashboard) ini menggunakan model prototype requirement. Penelitiaan ini bertujuan membangun sistem informasi monitoring (dashboard system) yang memberikan kemudahan kepada manager dalam monitoring laporan finance PT. Jakarta Maju Pusaka.
The Kartini reactor is a TRIGA-type research reactor with an operating power of 100 kW. The Kartini reactor was built in 1974 and is used for research, irradiation, education, and training purposes. In 2004, this reactor failed to display the fuel temperature in the control room. Therefore, a simple system is made to temporarily show the fuel temperature value while the fuel temperature display in the control room is improved. This system is designed to measure reactor fuel temperatures up to 250 0C. This system consists of an operational amplifier circuit (op-amp), an active low-pass filter circuit, an analog-to-digital converter circuit, and an AT89S51 microcontroller with an LCD circuit. First, the method converts the analog input into a digital value using ADC-0809. Next, the microcontroller's digital data from ADC-0809 is compared with the temperature value of the type K thermocouple. Finally, the temperature value (in 0C) closest to the digital value resulting from the ADC conversion is displayed by the microcontroller via a liquid crystal display. The results of the equipment being made satisfactory are proven by measurements of the Kartini reactor, which was operated for 4.5 hours at a power of 100 kW showing the temperature value on the core in ring B with a value of 117 0C. The voltage vs. temperature table on the K-type thermocouple has validated this temperature value. Keywords: reactor fuel temperature, microcontroller, analog to digital converter.
