Ahmad Taufik — Thu, 26 Sep 2024 00:00:00 +0000

Sei Padang Dam is a dam that dams the flow of the Padang River specifically to meet the needs of 3 irrigation areas, namely Paya Lombang, Langgau and Bajayu. Sei Padang Dam is currently only used as an irrigation channel and the potential energy that can be produced is not yet known. This study utilizes dam structures that have been completed such as intake channels, headrace channels, forebays and tailrace channels. This potential analysis was carried out using several methods, such as measuring the head using Google Earth, and using irrigation water discharge data from BWS Wil II Sumatra. The results of the study showed that Sei Padang Dam has a PLTMH potential of 50 kW with a water discharge of 2 m3/second and a water fall height/head reaching 4 meters. The most optimal turbine type is the Archimedes screw turbine type.

Implementasi Recurrent Neural Network Sebagai IDS Terhadap Serangan Jaringan

Fransko Gultom, Rosyidah Siregar — Mon, 30 Sep 2024 00:00:00 +0000

In recent years, a new term has emerged which is now widely applied as IDS (Intrusion Detection System), namely Deep Learing. One type of Deep – Learing is RNN (Recurrent Neural Network) which has recently been applied to IDS. Cyber attacs cannot be avoided, but they can be anticipated by building a system than can detect the performance of network data flows so that users can avoid all kinds of attacks and intrusion attempts from unknown parties. This research aims to test and analyse the accurary and speed of the Recurrent Neural Network in detecting attacks. The method used for this research is RNN, which is operated through the Python and Google Colab programs. Based on the results, the model was trained with 50 epochs resulting in an accurary of 92%. Meanwhile, a model with 30 epochs produces an accurary of 99%. So, the model can work well on training data with a total of 30 epochs.

The main problem in choosing an e-commerce platform for an online business is finding the one that best suits the specific needs of the business. Each platform has its advantages and disadvantages, such as ease of use, cost, features offered, as well as support for inventory management, shipping, and payments. Other challenges include ensuring that the platform can support future business growth, offer good scalability, and provide flexibility in terms of customization and integration with digital marketing tools. In addition, data security and a good user experience are also important considerations for long-term success. The purpose of this study is to implement the MABAC method and Entropy weighting in determining the best e-commerce platform for online businesses, so that this research can provide clear and data-driven recommendations to stakeholders regarding the most effective e-commerce platform. The application of the MABAC method combined with Entropy weighting in determining the best e-commerce platform for online business people offers a comprehensive and objective approach in decision-making. This combination not only improves decision-making accuracy, but also ensures that the most important criteria are weighted accordingly, resulting in more reliable results in choosing the best platform for business needs. The final result of the MABAC Platform A score is the first choice, considering the highest score of 0.82, which indicates its optimal performance in meeting the criteria that have been set. In addition, Platforms B and C, with scores of 0.78 and 0.75, respectively.

Kajian Pemilihan Sistem Drainase Berkelanjutan dalam Penanggulangan Banjir Perkotaan di Kec. Medan Selayang, Kota Medan

Fikri Auza’i Ikhwan — Mon, 30 Sep 2024 00:00:00 +0000

Medan Selayang sub-district is one of the sub-districts in Medan City that experiences urban flooding problems. There are at least seven flood points found in the area. Until now, the solution has been to increase the size of the existing drainage channels, which is still a conventional drainage system that adheres to the concept of grey infrastructure. Therefore, it is necessary to find a new method of solving urban flooding problems that is more sustainable, where rainwater can flow and not cause flooding, but also has the opportunity to be absorbed into the soil layer to increase groundwater reserves. Sustainable drainage systems are one method that can solve these problems. There are at least ten methods in sustainable drainage system, therefore a decision-making analysis is needed to select the most appropriate infrastructure to be implemented in Medan Selayang Sub-district. Decision-making is done with the Simple Additive Weighting (SAW) method and the following order is obtained: First place with a score of 130 is occupied by rainwater harvesting, followed by permeable pavement and rain garden with a final score of 128 each.

Penerapan Metode Waterfall dalam Pengembangan Aplikasi Edukasi Pelestarian Mangrove Berbasis Mobile

The mangrove ecosystem plays a vital role in maintaining coastal environmental balance. However, mangrove degradation continues to increase due to a lack of public awareness and education about its benefits and conservation methods. This study aims to develop a mobile-based educational application focused on introducing mangroves, highlighting their benefits, and demonstrating conservation techniques. The Waterfall method was applied in its development, consisting of the stages of requirements analysis, design, implementation, testing, and maintenance. This method was chosen for its structured and systematic approach, allowing for a well-planned application development that meets user needs. Testing results indicate that this application provides educational information interactively and is easily accessible to a broad audience, especially students and coastal communities. This application is expected to raise public awareness of the importance of mangrove conservation and serve as an effective solution in disseminating information about the mangrove ecosystem

Optimalisasi Pemilihan Title untuk Senjata pada Game Point Blank Menggunakan Metode TOPSIS

Derry Herlan Koto, Haida Dafitri — Mon, 30 Sep 2024 00:00:00 +0000

One of the main features in the point blank game is the title system, the benefit of the title gives the effect of the character gaining additional abilities and increased performance when using weapons. The purpose of this study is to create a website-based decision support system that can help point blank game players in choosing the optimal title combination for weapons, then a decision support system test is carried out using a data sample which will later be compared with the results of the manual calculation of the data sample, to obtain this purpose the method used in this study is the TOPSIS. The TOPSIS method is used because it is one of the methods in multi-criteria decision-making, which is known for its ease in calculating and interpreting results. Based on the results of the TOPSIS method calculation trial using a sample of 8 alternative and 7 criteria data, which were calculated manually and using the decision support system of this study, both produced title still assassin with a prevalence value of 0.36, title nimble sneaker with a prevalence value of 0.36, and title shooting star with a prevalence value of 0.325 are the recommendations of the results of this study for the combination of titles which fills 3 title slots in Game Point Blank for the use of assault rifles, sub machine guns, snipers, and shotguns.
