Analisis Penyetelan Proteksi Arus Lebih Penyulang Cimalaka Di Gardu Induk 70 Kv Sumedang

20 kV distribution of PLN is not free from distractions short circuit. Greatest short circuit fault current occurs at 20 kV bus bar. This led to widespread outages as a result of the major security operation. The aim of this study was to identify the final interruption of short circuit current, short circuit fault current to calculate and determine the values Over Current Relay (OCR) and Ground Fault Relay (GFR). This study purposed to calculate short circuit current. The subject of research is the disturbances that occurred in Cimalaka feeders. The data required for this study were obtained from the Area Manager Distribution of Bandung. The data is analyzed to determine the magnitude of short circuit current and Over Current Relay (OCR) and Ground Fault Relay (GFR) adjustment. The results show the short circuit fault current at 0% distance from feeder is 2428,391 A and short circuit current for 3 phase is 2103,049 A short circuit fault current and the second phase of 570,406 A short circuit fault current one phase to the ground. The difference in the relay settings data from the field with the calculation results showed that the differences are not too significant, so the ability of the relays is still good. Thus, the feeder protection relays Cimalaka at 70 kV substation Sumedang still good and doesn't need to be reset. Keywords: Over Current Rela

Kepemimpinan Transformasional Pada Organizational Citizenship Behavior Dan Komitmen Afektif

The aims of this study are to explore a number of antecedents that affect the organizational citizenship behavior. The antecedent of organizational citizenship behavior is transformational leadership while affective commitment serves as a mediation variable. The respondents in this research are lecturers at private universities in Special Province of Yogyakarta Province. The number of samples used is 145 respondents by using purposive sampling. The analytical technique used in this study is Structural Equation Modeling (SEM). Based on the analysis, the influence of transformational leadership on the behavior of organizational citizenship is positively significant while transformational leadership to the affective commitment has significant positive effects, and the same also for affective commitment to behavior organizational citizenship which has a significant positive effect. The results of this study explain the phenomenon of organizational citizenship behavior among the lecturers which is increasingly demanding profession. The role of transformational leadership and affective commitment of lecturers are also becoming increasingly important

“M-Auto” The Augmented Reality-Based (AR) Learning Media Application for the Finite-State Automata (FA) Reduction Subject of Language and Automata Theory Courses

AbstractA proper learning process should contain innovative, amusing, challenging, and motivating aspects. It should be able to provide an opportunity for the students to develop their creativity and independence based on their interests and talent. Less interesting and tedious classroom learning activity indicates the factor of the students’ learning interest degradation, for example as in the language and automata theory and finite-state automata reduction subject. The current research aims to aid language and automata theory in a learning activity to be easier to acquire. With the Augmented Reality-based learning media, the researcher hopes that the students can develop their understanding and their interest in a learning activity, especially for finite-state automata subjects. The subject of the current research is the Augmented Reality-based application as the learning media for language and automata theory and finite-state automata material. The researcher employs several research methodologies such as literature review, library research, and questionnaire to support the current research. The application is designed according to system development that consists of problem identification, appropriateness study, need analysis, concept designing, content designing, script designing, graphic designing, system production, and system examination. The result of the current research is the AR-based learning media application for the finite-state automata reduction subject of language and automata theory. Keywords: Learning Media, Finite-State Automata Reduction, Augmented Realit

Audit Sistem Keamanan TI Menggunakan Domain DSS05 pada Framework COBIT 5 (Studi Kasus: Diskominfo Kabupaten Karawang)

—Keamanan informasi pada era digital sangat penting, sehingga menjadi masalah penting bagi Perusahaan, organisasi, serta lembaga pemerintahan. Dinas Komunikasi serta Informatika Kabupaten Karawang didirikan berdasarkan Peraturan Daerah No.14 pada Tahun 2016 mengenai Pembentukan serta Susunan Perangkat Daerah Kabupaten Karawang. Pemanfaatan teknologi informasi sudah diterapkan dalam sistem keamanan informasi pemerintah Kabupaten Karawang. namun dalam mewujudkan hal itu, belum sepenuhnya berhasil dalam pengambilan nilai serta manfaatnya. Riset ini mempunyai tujuan untuk melakukan evaluasi keamanan sistem informasi yang telah diimplementasikan pada institusi untuk menilai level kapabilitas menggunakan domain DSS05 pada COBIT 5. Metode yang dipakai yaitu Assesment Process Activities COBIT 5 antara lain Initiation Programme, Define Problems and Opportunities, Data Collection, Data Validation serta Process Atribut Level. Hasil riset ini didapatkan nilai kapabilitas 3,4 (as is) serta 4.1 (to be) maka proses yang telah diimplementasikan secara garis besar tercapai. Pada domain DSS05 mendapatkan capaian sebesar 92% berarti pada proses atribut 3.1 process definition tercapai penuh, sehingga penilaian dapat dilanjutkan ke level berikutnya yaitu (PA) 3.2 Process Deployment

Pengaruh Suhu Hydriding terhadap Laju Korosi Material Struktur Reaktor Nuklir Berbasis Paduan Zirconium dan Baja Tahan Karat

. Pengaruh Suhu Hydriding Terhadap Laju Korosi Material Struktur Reaktor Nuklir Berbasis Paduan Zirconium dan Baja Tahan Karat. Material struktur reaktor nuklir akan berada dalam lingkungan yang dipengaruhi oleh paparan radiasi dan temperatur tinggi sehingga harus dipastikan integritas mekaniknya. Tujuan dari penelitian ini adalah untuk mempelajari pengaruh hydriding terhadap laju korosi material kelongsong bahan bakar dan material struktur lainnya berbasis paduan zirconium dan baja tahan karat dalam larutan air demin. Uji korosi elektrokimia dilakukan pada suhu kamar untuk menghilangkan pengaruh suhu tinggi dan tekanan pada proses elektrokimia. Pada penelitian ini dilakukan pengamatan laju korosi material zircaloy-2 yang telah di hidriding pada suhu 150 °C dan 500 °C. Hasil pengamatan didapatkan bahwa zircaloy-2 lebih mudah bereaksi korosi dibandingkan dengan SS 304 dan 316. Suhu hydriding 500 °C dapat menurunkan energi potensial korosi pada material SS 304 dan SS 316, hal yang sama juga terjadi pada zircaloy-2. Dapat disimpulkan bahwa Perlakuan hydriding berpengaruh terhadap karakteristik korosi material cladding zircaloy-2, SS 304 dan SS 316 dalam air demin yaitu laju korosi yang terjadi pada zircaloy-2, SS 304 dan SS 316 akan semakin meningkat seiring dengan kenaikan suhu hydriding

Proceedings of the 3rd International Conference on Community Engagement and Education for Sustainable Development

This proceeding contains articles on the various ideas of the academic community presented at The 3rd International Conference on Community Engagement and Education for Sustainable Development (ICCEESD 2022) organized by the Universitas Gadjah Mada, Indonesia on 7th-8th December 2022.  ICCEESD is a biannual forum for sharing, benchmarking, and discussing HEI’s activities in developing Education for Sustainable Development towards community engagement. Education for Sustainability as a teaching strategy for resolving community challenges through formal, informal, or non-formal education is expected to benefit from various community service best practices by academics, researchers, and students. The 3rd ICCEESD has “Strengthening Education for Sustainability Towards Better Community Engagement” as its theme this year. It is expected that the 3rd ICCEESD will provide a forum for the presenters and participants to exchange best practices, policies, and conceptual implementation of Education for Sustainability towards better community engagement and explore ideas to address community needs.  Conference Title: 3rd International Conference on Community Engagement and Education for Sustainable DevelopmentConference Theme: Strengthening Education for Sustainability Towards Better Community EngagementConference Acronyms: ICCEESD 2022Conference Date: 7th-8th December 2022Conference Location: Grand Rohan Jogja Yogyakarta, IndonesiaConference Organizer: Universitas Gadjah Mada, Indonesi
