Abstract

Vibration testing on telemetry system payload is needed to determine its resistance to vibration during operation. Vibration testing of telemetry system payloads requires a test fixture. Test fixture is used to transmit vibration from shaker to telemetry system payload. The payload of telemetry system to be tested is a tubular. The test fixture in this study was designed using SolidWorks software. The material used for manufacture of test fixture is aluminum. Aluminum material was chosen because it has good rigidity with a relatively light mass. Stiffness and mass properties affect to natural frequency value of test fixture, which must be greater than the frequency range of operating telemetry system. Data collection uses two accelerometers placed on test fixture. Sine sweep vibrations are given from 5 Hz to 2000 Hz with a constant amplitude of 1 g and a sweep rate of 1 octave/minute. The test produces three peaks that they are candidates as natural frequencies, i.e at a frequency of 1532 Hz with an amplitude of 2.898 g, a frequency of 1706 Hz with an amplitude of 6.582 g, and at a frequency of 1806 Hz with an amplitude of 6.472 g. From those three natural frequencies, the second natural frequency at 1706 Hz is the most critically because it has the largest response value.

Abstract

Efficiently managing academic information systems (AIS) is essential for educational institutions to provide reliable services to students and faculty. This research explores the integration of HAProxy load balancing and file synchronization techniques to optimize the performance of AIS. HAProxy is employed to distribute incoming requests across multiple backend servers, and the backend will call web service to access the data saved in the database to facilitate seamless data sharing and access. Additionally, file synchronization mechanisms are implemented to maintain consistency across scripts used in the backend system. The study conducts performance evaluations and benchmarks to assess the impact of HAProxy load balancing and file synchronization on AIS responsiveness and reliability. The results reveal significant system scalability and fault tolerance improvements, reducing downtime and enhancing user experience. This research contributes to optimizing academic information systems, enhancing their ability to handle increased loads, and ensuring the efficient delivery of educational services.

Abstract

Undang-undang Pelindungan Data Pribadi (UU PDP) telah disahkan oleh DPR pada 17 Oktober 2022 lalu menjadi UU No 27 Tahun 2022 tentang Pelindungan Data Pribadi. Salah satu pasalnya menyebutkan bahwa UU ini akan mulai berlaku 2 tahun setelah diundangkan yaitu 17 Oktober 2024. Artinya, semenjak UU ini berlaku pada Oktober 2024 nanti, maka sanksi-sanksi terhadap pelanggaran UU ini juga akan berlaku. Mengingat status tersebut maka sudah selayaknya untuk UIN Sunan Kalijaga memperhatikan dengan baik implementasi UU PDP tersebut. Pada penelitian ini, pengetahuan dan persiapan para ASN di UIN Sunan Kalijaga akan disurvei dan dievaluasi. Dari sisi persiapan, afeksi ASN terhadap implementasi ini akan ditanyakan. Dari total ASN sebanyak 1009 orang, ada 152 responden yang menjawab dengan lengkap. Survei dilakukan pada November dan Desember 2024. Hasil dari survei menunjukkan bahwa secara umum responden dalam hal ini adalah ASN di UIN Sunan Kalijaga sudah cukup memahami tentang keberadaan dan konsekuensi dari UU PDP ini. Akan tetapi, mereka juga banyak yang menyatakan bahwa UIN Sunan Kalijaga sebagai institusi belum siap untuk menghadapi konsekuensinya. Oleh karena itu, perlu dilakukan sosialisasi ulang dan penambahan infrastruktur keamanan informasi agar tidak terkena jerat pidana maupun perdata di kemudian hari. Analisis data juga menunjukkan bahwa tidak ada perbedaan pengetahuan dan afeksi untuk beberapa kelompok responden sehingga kegiatan-kegiatan terkait implementasi UU PDP harus melibatkan semua pihak dan semua level jabatan. Kata kunci: Personal Data Protection Act, UIN Sunan Kalijaga, Information Security ------------------------------- Abstract The Personal Data Protection Act (PDP Act) was enacted by the Indonesian House of Representatives on October 17, 2022, becoming Law No. 27 of 2022 on Personal Data Protection. One of its articles states that the law will take effect two years after its promulgation, specifically on October 17, 2024. This means that starting from October 2024, the sanctions for violations of this law will also come into force. Given this status, it is imperative for UIN Sunan Kalijaga to carefully consider the implementation of the PDP Act. In this study, the knowledge and preparedness of civil servants (ASN) at UIN Sunan Kalijaga were surveyed and evaluated. Regarding preparedness, the affective response of the civil servants toward the implementation of this law was assessed. Out of a total of 1,009 civil servants, 152 respondents provided complete responses. The survey was conducted in November and December 2024. The results of the survey indicate that, in general, the respondents, who in this case are civil servants at UIN Sunan Kalijaga, have a reasonable understanding of the existence and implications of the PDP Act. However, many also expressed that UIN Sunan Kalijaga as an institution is not yet prepared to face its consequences. Therefore, further dissemination and the enhancement of information security infrastructure are necessary to avoid criminal or civil liabilities in the future. Data analysis also shows that there is no significant difference in knowledge or affective response across various groups of respondents. Hence, activities related to the implementation of the PDP Act must involve all parties and all levels of positions within the institution.

Abstract

Electrical Conductivty (EC) merupakan besaran fisika dan mekanika tanah yang digunakan sebagai indikator salinitas tanah dan ketersediaan nitrogen untuk tanaman. EC juga menjadi besaran untuk memperkirakan sifat tanah lainnya, seperti kelembaban tanah dan kedalaman tanah. Konduktivitas listrik tanah dapat diukur karena adanya elektrolit yang terlarut dalam partikel dan larutan tanah. Tujuan dari penelitian ini adalah untuk melakukan kalibrasi silang sensor EC pada soil comprehensive sensor tipe RS485 terhadap WET-2 sensor. Kalibarsi dilakukan agar mendapatkan nilai yang tepat dan sesuai untuk mewakili kondisi lingkungan yang diinginkan.  Pada penelitian ini kalibrasi dilakukan pada 40 titik sampel lapangan di Badan Riset dan Teknologi Nasional (BRIN) Teknologi Penerbangan (TEKBANG) Kecamatan Rumpin, Kabupaten Bogor. Hasilnya menunjukkan nilai R square 0.8127 memberikan informasi bahwa hubungan antara sensor dan kalibrator sangat tinggi, kemudian multiple R sebesar 0.9015 mengindikasikan hubungan yang kuat antara sensor dan kalibrator. Hal ini menunjukan bahwa sensor yang digunakan cukup mampu mewakili nilai kalibrator.

Abstract

Shrimp farming requires a touch that must be right on the side of water quality; water is a fundamental factor that must be met to achieve maximum yields. Many factors affect the quality of the water, but some things cause changes in water quality caused by external and internal factors causing death in shrimp. Disease conditions in shrimp can attack at any time, coupled with external factors such as extreme climate change, and cause changes in water components such as water pH, CaMg or hardness, and other factors that cause death in shrimp. Water turbidity oxygen demand (DO) in water determines the life of shrimp. It is coupled with microorganisms that must be maintained to maintain water quality for the growth of a Vaname shrimp.

Abstract

In this paper, the authors present an approach of reliability analysis to analyze the landing gear control and warning system, which is planned to be installed on LSA-02 aircraft. The reliability analysis will use fault tree analysis as starting point to investigate what is the top undesired event which might occur in this system. The construction of causal tree analysis offers a framework privileged to the deductive analysis, which consists of seeking the various possible combinations of events, leading to the occurrence of a top undesired event. The fault tree analysis shows that the top undesired event for this system is when the landing gear is commanded to extended, the system fails to extend the landing gear, and warning system is failed to operate.
