Abstract

Job vacancies are information that is really needed by many people with a very fast update rate, because it is related to the acceptance deadline. Speed of information and suitability of abilities are basic criteria in the job search process when applying for jobs. However, the distribution of this information is quite difficult to obtain when you have to look for the source of the information in certain places first. For this reason, a solution is needed to simplify these difficulties. The software development methodology used in the system development process is the waterfall methodology. In this methodology, several steps are taken to build software, namely software engineering, system analysis, system design, system implementation, system testing. By carrying out stages based on the methodology, it is hoped that the application will be built according to needs and can be used by consumers. The Job Seeker Application is an application that can help disseminate job vacancy information for job seekers and employers to assist the job application process directly for job seekers.

Abstract

The implementation of Carrier Aggregation makes it possible to expand spectrum use by combining several bandwidth channels that work like a single spectrum. The LTE network is deployed on several bandwidth channels, namely 1.4MHz, 3MHz, 5MHz, 10MHz, 15MHz and 20MHz. Each bandwidth channel that is correlated with the implementation of carrier aggregation will occupy a different and non-adjacent frequency band, namely 900MHz, 1800MHz, 2100MHz and 2300MHz. In this research, we tested the effect of a combination of CAs that occupy non-adjacent frequency bands on uplink and downlink performance. Measuring and analyzing network performance to determine throughput using several supporting software, namely Tems Investigation, Tems Discovery and Gnet Track. There was an increase in the downlink throughput and uplink throughput values due to the implementation of CA compared to not using CA. The maximum Downlink Throughput value in the CA combination is greater than the Uplink Throughput. The maximum Downlink throughput value on CA 20+20Mhz is 9427kbps, while the Uplink value is 1133.28kbps. The maximum downlink throughput value on CA 20+15Mhz is 8272.24kbps, and the maximum uplink throughput value is 745kbps.

Abstract

Extended Producer Responsibility (EPR) is a program that holds industries accountable for their products' environmental impact throughout their lifecycle. To guide EPR implementation, Indonesia's Ministry of Environment and Forestry issued Regulation P.75/2019 on waste reduction by producers. One key government initiative is optimizing partnerships for post-consumer packaging waste collection through Waste Banks, TPST3R, Recycling Centers, and digital platforms. This research introduces NaimaEcoSync, a platform designed to streamline waste take-back by integrating waste management data and mapping reports for industries. Developed using the Scrum methodology, NaimaEcoSync achieved a usability score of 96.07%. The platform contributes to industry sustainability by reducing waste and supporting EPR implementation in Indonesia

Abstract

Abstract: This system for predicting volcanic eruptions will produce information that can help BMKG in making decisions to provide warnings to residents around the mountain. This will also help in mitigating volcanic eruptions, evacuating residents in volcanic eruptions. By using artificial neural networks with the backpropagation method, it can be used to predict volcanic eruptions. To conduct this test, criteria and factors that influence this volcanic eruption are needed. This method is tested using Matlab 6.1 software. In this test, various patterns will be carried out to compare the results of the network. From the various patterns tested, it can be seen that the number of epochs used affects the test results and will achieve the desired goal. The more epochs used, the faster the goal will be achieved. Where in the 4-2-1 pattern the goal was found in the 7th epoch with an error value of 0.0987135. This 4-2-1 pattern states that this network is tested with 4 input layers, 2 hidden layers and 1 output layer. The α value (α = learning rate) used is the Default value of 0.1. With this backpropagation method, you get more accurate results by getting smaller error values.            Keywords: backpropagation, matlab 6.1, layer, epoch, goal Abstrak: Sistem untuk memprediksi gunung meletus ini akan menghasilkan informasi yang bisa membantu BMKG dalam mengambil keputusan untuk memberikan peringatan kepada warga sekitar gunung. Hal ini juga akan membantu dalam mitigasi bencana gunung meletus , evakuasi warga sekitar dalam bencana gunung meletus. Dengan menggunakan jaringan saraf tiruan dengan metode backpropagation bisa digunakan untuk memprediksi gunung meletus. Untuk melakukan pengujian ini dibutuhkan kriteria dan faktor yang mempengaruhi gunung meletus ini. Metode ini diuji dengan menggunakan software Matlab 6.1. Pada pengujian ini akan dilakukan dengan berbagai pola untuk membandingkan hasil dari jaringan tersebut. Dari berbagai pola yang diuji dapat dilihat bahwa jumlah epoch yang dipakai mempengaruhi hasil pengujian dan akan mencapai goal yang diinginkan. Semakin banyak epoch yang dipakai maka akan semakin cepat goal tersebut dicapai. Dimana pada pola 4-2-1 goal ditemukan pada epoch ke 7 dengan nilai eror 0,0987135. Pola 4-2-1 ini menyatakan bahwa jaringan ini diuji dengan 4 jumlah input layer, 2 hidden layer dan 1 output layer. Nilai α  (α = learning rate) yang digunakan adalah nilai Default yaitu 0.1. Dengan metode backpropagation ini mendapatkan hasil yang lebih akurat dengan mendapatkan nilai eror yang lebih kecil . Kata kunci: backpropagation ; epoch ; goal ; layer ; matlab 6.1

Abstract

Abstract: The internship recruitment process at PT Semen Padang was previously conducted manually, leading to issues such as data duplication, delays in selection, and limited information transparency. This study aims to design and implement a web-based information system to digitalize the entire internship registration and selection process. The system was developed using the Laravel framework and MySQL database, adopting the waterfall development method consisting of requirements analysis, system design (using Figma and Draw.io), implementation, and black-box testing. The results show that the system effectively improves the registration process, expedites document verification, and provides real-time selection status updates for applicants. Key features include online registration, document upload, status monitoring, admin verification, and automated report generation. Based on the testing results, all features function as intended without significant issues. In conclusion, the system contributes to enhanced data accuracy, operational efficiency, and transparency in the internship admission process. The system also has potential for future enhancements, such as automated notifications and academic system integration. Keywords: Information system, internship, Laravel, MySQL, waterfall, digitalization, transparency, efficiency Abstrak: Proses penerimaan peserta magang di PT Semen Padang sebelumnya dilakukan secara manual, yang menimbulkan berbagai kendala seperti duplikasi data, keterlambatan proses seleksi, dan minimnya transparansi informasi. Penelitian ini bertujuan untuk merancang dan mengimplementasikan sistem informasi berbasis web untuk mendigitalisasi proses seleksi magang secara menyeluruh. Sistem dikembangkan menggunakan framework Laravel dan database MySQL, dengan pendekatan metode pengembangan waterfall yang terdiri atas tahapan analisis kebutuhan, perancangan sistem (menggunakan Figma dan Draw.io), implementasi, serta pengujian menggunakan metode black-box. Hasil penelitian menunjukkan bahwa sistem mampu meningkatkan efisiensi proses pendaftaran, mempercepat verifikasi dokumen oleh admin, serta memberikan akses informasi seleksi secara real-time kepada peserta. Fitur utama sistem meliputi pendaftaran online, unggah dokumen persyaratan, pemantauan status seleksi, verifikasi data oleh admin, dan cetak laporan otomatis. Berdasarkan hasil pengujian, seluruh fitur berfungsi sesuai kebutuhan tanpa ditemukan kendala signifikan. Kesimpulannya, sistem ini berkontribusi dalam meningkatkan akurasi data, efisiensi operasional, dan transparansi proses penerimaan peserta magang. Sistem ini juga memiliki potensi untuk dikembangkan lebih lanjut dengan penambahan notifikasi otomatis dan integrasi sistem akademik kampus. Kata kunci: Sistem informasi, magang, Laravel, MySQL, waterfall, digitalisasi, transparansi, efisiensi.
