Abstract

Abstract - System reliability becomes an important part in the distribution of electrical energy. Disruptions from both internal and external factors that caused a long duration blackouts and often occured can affect the level of system reliability, in fact the blackouts that occured can cause cost losses due to undistributed energy. Therefore, it needs to calculate the reliability index based on SAIFI (System Average Interruption Frequency Index) and SAIDI (System Average Interruption Duration Index) in North Minahasa area which have 9 feeder from 4 main station and compare the result of calculating with PLN, IEEE, and WCS&WCC standard which has been multiplied with Sulawesi area adjustment factors by 1.3 and the calculation of cost loss experienced due to blackouts in 2019 and 2020. Based on the calculation result and analysis shows that almost all feeder in 2019 and 2020 had SAIFI and SAIDI value exceeding the standard except SW 2 feeder with SAIFI and SAIDI value by 0,00028 times/customer/year and 0,00083 hours/customer/ year in 2019 and in 2020 by 0,00011 times/customer/year and 0,00032 hours/customer/year. With the total of cost loss in 2019 and 2020 is Rp.2.069.227.200 and Rp.859.432.000. All the feeders that do not exceed the standard can be said reliable and the feeders that exceed the standard is unreliable. Keywords - Cost loss; North Minahasa; Reliability; SAIDI; SAIFI. Abstrak - Keandalan sistem menjadi bagian penting dalam pendistribusian energi listrik. Gangguan- gangguan baik oleh faktor internal maupun eksternal yang menyebabkan pemadaman yang durasinya begitu lama dan sering terjadi dapat mempengaruhi tingkat keandalan sistem, bahkan pemadaman yang terjadi dapat menimbulkan kerugian biaya karena energi yang tidak tersalurkan. Untuk itu perlu dilakukan perhitungan indeks keandalan berdasarkan SAIFI (System Avarage Interruption Frequency Index) dan SAIDI (System Avarage Interruption Duration Index) di area Minahasa Utara yang terdapat 9 penyulang dari 4 Gardu Induk dan membandingkan hasil perhitungan dengan standar PLN, IEEE, WCS&WCC yang telah dikalikan dengan faktor   penyesuaian daerah Sulawesi sebesar 1,3 serta perhitungan kerugian biaya yang dialami akibat adanya pemadaman tahun 2019 dan 2020. Berdasarkan hasil perhitungan dan analisa menunjukkan bahwa hampir semua penyulang di tahun 2019 dan 2020 memiliki nilai SAIFI dan SAIDI melebihi standar kecuali penyulang SW 2 dengan nilai SAIFI dan SAIDI tahun 2019 sebesar 0,00028 kali/pelanggan/tahun dan 0,00083 jam/pelanggan/tahun serta tahun 2020 sebesar 0,00011 kali/pelanggan/tahun dan 0,00032 jam/pelanggan/tahun. Dengan total kerugian biaya di tahun 2019 dan 2020 sebesar Rp.2.069.227.200 dan Rp.859.432.000. Semua penyulang yang tidak melebihi standar dapat dikatakan andal dan yang melebihi standar dapat dikatakan tidak andal. Kata kunci – Kerugian Biaya; Minahasa Utara; Keandalan; SAIDI; SAIFI.

Abstract  — This study aims to analyze the efficiency of two dominant animation methods Motion Capture and Keyframe Animation in contemporary animation production. Using a qualitative descriptive approach supported by a literature review and document observation from 20 academic and industrial sources (2022–2024), this research highlights critical aspects such as production time, motion realism, creative flexibility, and resource allocation. The results show that Motion Capture excels in speed and naturalistic movement reproduction, making it ideal for realistic characters in film and video games. However, Keyframe Animation offers superior stylization and control, suitable for creative storytelling and exaggerated motion. The study concludes that both methods have strategic relevance depending on production context and recommends hybrid workflows as an emerging solution in modern animation pipelines. Keywords — Motion Capture, Keyframe Animation, animation efficiency, character movement, hybrid animation   Abstrak — Penelitian ini bertujuan untuk menganalisis efisiensi dua metode animasi utama Motion Capture dan Keyframe Animation dalam produksi animasi kontemporer. Dengan pendekatan deskriptif kualitatif yang didukung studi pustaka dan observasi dokumentasi dari 20 sumber akademik dan industri (2022–2024), penelitian ini menyoroti aspek penting seperti waktu produksi, realisme gerak, fleksibilitas kreatif, dan alokasi sumber daya. Hasil penelitian menunjukkan bahwa Motion Capture unggul dalam kecepatan dan reproduksi gerakan alami, menjadikannya ideal untuk karakter realistis dalam film dan video game. Namun, Keyframe Animation menawarkan gaya dan kontrol yang lebih ekspresif, cocok untuk penceritaan kreatif dan gerakan yang dilebih-lebihkan. Studi ini menyimpulkan bahwa kedua metode memiliki relevansi strategis sesuai konteks produksi, dan merekomendasikan pendekatan hibrida sebagai solusi inovatif dalam pipeline animasi modern.

Abstract

Traditional dance is an important part of cultural heritage that reflects the identity and values of the community. Minahasa has various traditional dances, such as the Kabasaran, Maengket, and Pisok dances, which are rich in philosophical and historical meaning. However, the younger generation's interest in traditional dances tends to decline due to the lack of interesting and interactive learning media. Virtual Reality (VR) technology offers an innovative solution in cultural preservation by creating an immersive experience that allows users to interact in a three-dimensional environment. This research aims to develop a Virtual Reality-based application as a medium for introducing Minahasan Traditional Dances so that it can be accessed anytime and anywhere. The system design method includes concept, design, material collection, assembly, testing, and distribution. The test results show that the VR application can run well on the device used and can display the dance stably. The result of this research is a Virtual Reality application that can introduce Minahasan dances and support the preservation of Minahasan culture.

Abstract

Abstract — A university's strategic objectives need to be systematically aligned with InformationTechnology (IT) governance to ensure IT truly supports the achievement of the institution's vision and mission. An effective method to achieve this goal is by using the COBIT 2019 framework. The approach taken is a two-stage mapping process. The first stage involves translating the university's Vision and Mission into COBIT's Enterprise Goals (EG). Then, in the second stage, each EG is mapped to the relevant IT Alignment Goals (AG). This step-by-step mapping process serves as a bridge connecting the university's high-level strategic direction with specific IT management activities and objectives. The result of this method is the creation of a clear and measurable connection between the university's strategic objectives and the main focus areas of IT governance, namely Value, Risk, and Performance. This connection shows how each university objective is influenced or supported by IT governance efforts. The implications are significant, as the mapping results become a strong foundation for developing the university's IT roadmap. Additionally, it helps the institution prioritize which COBIT management and governance domains should be optimized first to align with the institution's most pressing strategic needs. Thus, IT transforms from merely a supporting function into a strategic driver for the university. Key words — COBIT 2019; Enterprise Goals; Alignment Goals; IT Governance; Higher EducationStrategy; Strategic Mapping.
