Abstract

Abstrak— Sistem informasi saat ini telah menjadi kebutuhan pada masyarakat untuk membantu dalam menyelesaikan berbagai pekerjaan. Masyarakat telah menyadari akan pentingnya keberadaan sistem informasi dalam membantu memonitoring pekerjaan yang sudah dilakukan maupun sebagai bentuk untuk pengolahan data yang lebih mudah dibandingkan dengan cara manual. Salah satu bentuk implementasi sistem informasi akuntansi adalah pengelolaan dana biaya operasional sekolah. Dimana pada biaya operasional sekolah lebih mengarah pada akuntansi dikarenakan pengolahan didalamnya sesuai dengan keilmuan dibidang akuntansi. Oleh karena itu, supaya penggunaan dana BOS bisa dipertanggungjawabkan maka diperlukan sebuah sistem dalam pengelolaan dan monitoringnya. Pembuatan sistem informasi akuntansi biaya operasional sekolah diperlukan supaya bisa membantu para pengelola dana BOS dalam memonitoring dan mengevaluasi setiap penggunaan dana BOS. Perancangan dalam pembuatan sistem informasi akuntansi biaya operasional sekolah ini lebih tepatnya menggunakan metode rapid application development (RAD). Model RAD (rapid application development) merupakan model proses pengembangan perangkat lunak secara linier sequential yang menekankan pada siklus pengembangan yang sangat singkat. Black Box Testing berfokus pada spesifikasi fungsional dari perangkat lunak. Tester dapat mendefinisikan kumpulan kondisi input dan melakukan pengetesan pada spesifikasi fungsional program. Berdasarkan hasil pengujian sistem dengan menggunakan metode black box, aplikasi SIA BOS yang telah dibuat tidak ditemukan permasalahan dari sistem. Kata kunci— sistem informasi, akuntansi, dana BOS, RAD, black box.Abstract— The current information system has become a necessity for the community to assist in completing various jobs. The public has been aware of the importance of the existence of information systems in helping to monitor the work that has been done and as a form for data processing easier than the manual way. One form of accounting information system implementation is the fund management of school operational costs. Where on the operational costs of schools more leads to accounting because the processing therein in accordance with the scholarship in the field of accounting. Therefore, in order for the use of BOS funds can be accounted for, it is necessary a system in the management and monitoring. Creation of school operational cost accounting information system is needed to assist BOS fund managers in monitoring and evaluating every use of BOS funds. The design in making the information system of school operational cost accounting is more precisely use method of rapid application development (RAD). RAD model (rapid application development) is a model of sequential linear software development process that emphasizes on a very short development cycle. Black Box Testing focuses on the functional specifications of the software. The tester can define the set of input conditions and perform testing on the functional specifications of the program. Based on the results of testing the system using black box method, SIA BOS application that has been made not found problems from the system. Keywords— information systems, accounting, BOS funds, RAD, black box.

Abstract

Abstrak-Dalam bahasa Aceh teks emosi marah, senang, sedih, jijik dan normal dapat dinyatakan dalam bentuk verbal (menulis kata- kata). Emosi marah, senang, sedih, jijik dan normal juga dapat ditunjukkan dengan teks, akan tetapi tingkatan emosinya agak sulit ditebak disebabkan teks yang tidak dikenali suatu teks itu berupa emosi marah, senang, sedih, jijik dan bahkan emosi normal. Tingkatan emosinya agak sulit ditebak karena dalam bahasa aceh teks emosi belum tentu dapat digambarkan dengan pasti perasaan emosi yang dirasakan oleh teks itu sendiri. Oleh karena itu, dibuat sebuah program aplikasi yang dapat mengetahui tingkat emosi seseorang. Penelitian ini bertujuan untuk membahas teks emosi marah melalui kalimat atau teks marah, senang, sedih, jijik dan normal dalam bahasa Aceh untuk memperoleh tampilan persentase tingkat emosi dari suatu teks. Program aplikasi ini menggunakan metode Term Frekuensi / Invers Dokument Frekuensi. Penelitian sistem aplikasi ini menghasilkan akurasi kebenaran prediksi sebesar 80%.

Abstract

Cloud storage is a technology used to store data online. However, this technology also poses problems in terms of security. Therefore, the author wants to build a cloud storage system by implementing cryptographic security to secure data. By implementing cryptographic techniques in cloud storage, users don't need to worry about data loss or theft. The cryptographic method applied is the Vigenere Cipher algorithm, which is a classic type of cryptography. Cloud storage is applied to public and private networks to test the comparison of data encryption times. Based on tests carried out, implementation on private networks is better with an average time of 3.84 seconds for encryption and 253.6 milliseconds for decryption. Meanwhile, on public networks, the average time is 45.3 seconds for encryption and 392 milliseconds for decryption. To measure whether cryptography is effective or not, the avalanche affect method is used which produces a value of 1.4% to 7% with an average of 3.92%.

Abstract

Water management is a very important role in the success of increasing rice production in fields. This study took a case study on irrigated rice fields. In an effort to improve the quality and efficiency of water management in rice fields, a good monitoring system is also needed. Generally, monitoring has been done manually so far, the interaction between farmers and irrigation officers is still using the telephone, which costs a lot of money. With the IoT (Internet of Things) technology, it can be applied to a monitoring system for managing water needs in rice fields using mobile-based AHP, which is a system that provides notifications in the form of information on water levels and the best humidity values for rice plants in rice fields in real-time and is able to deliver reports via internet transmission media. This study aims to obtain the value of report delivery speed through monitoring applications and to be able to detect water levels and soil moisture in paddy fields using the Analytical Hierarchy Process (AHP) method and sensor accuracy so that the results are as expected. The research data has been obtained by looking at the suitability of soil moisture information in the application with the ETP302 measuring instrument with an accuracy value of 86.12% and the water level in applications with an actual water level of 66.35%. In testing the speed of sending reports an average value of 1.67 s. In the best soil moisture detection test using the AHP method, the suitability value is up to 91.7% and the water level reaches 93.4%. The sensor can also be turned off or on through the monitoring application.

Abstract

Job vacancy info mobile application has now become an important tool for job seekers in the digital era since the COVID-19 pandemic which recorded a significant spike in the number of unemployed people in Indonesia. In facing this challenge, cloud computing implementation is a crucial solution. This research aims to test performance using the stress testing method and test cloud services from Google Cloud Platform using the Quality of Service (QoS) method. The results show that the server can withstand loads of up to 7000 users simultaneously within 180 seconds or 3 minutes. QoS testing shows that cloud services from Google Cloud Platform achieve an average throughput of 1301.4 kbps with a packet loss rate of 0.54%, an average delay of 0.0019 ms, and an average jitter of 0.00 ms. These results confirm that the implementation of cloud computing in the mobile application of job vacancy information can improve efficiency and quality of service, in accordance with the demands of a dynamic labor market and facing a significant surge in users.
