Vehicle parking is an absolute thing that is needed in public places or public facilities. Finding a parking spot becomes difficult in big cities, especially during rush hour. Parking system that already exists in several cities in Indonesia can provide information of the availability of parking at the entrance. However, this system is still not helping enough for the driver, they still need to find their own parking spot that is time consuming and can lead to jam or stuck in the parking area. In this study, a parking system with recommended parking location has been designed. Driver will receive printout of parking ticket from a thermal printer that contain the closest parking location to the entrance of the building or facility. From the results of tests performed, it has generated a parking system that can provide recommendations parking location by checking the order using microcontroller program. Each parking location equipped with parking sensors to detect the presence of vehicles. At the entrance, seven segment display provides information of the number of available parking slot. Keywords: microcontroller, parking location recommendation, parking sensor Tempat parkir kendaraan merupakan hal mutlak yang sangat dibutuhkan di tempat-tempat umum atau fasilitas publik. Menemukan tempat parkir kosong menjadi hal yang sulit di kota-kota besar terutama pada jam sibuk. Sistem parkir yang sudah ada di beberapa kota besar di Indonesia dapat memberikan informasi ketersediaan tempat parkir di pintu masuk. Namun sistem ini dirasa masih kurang membantu karena pengemudi masih harus mencari tempat parkir sendiri sehingga menghabiskan waktu dan dapat menimbulkan kemacetan di area parkir. Dalam penelitian ini dirancang sistem parkir dengan rekomendasi lokasi parkir. Pengendara akan penerima printout tiket dari printer termal yang bertuliskan lokasi parkir yang disarankan yaitu yang terdekat dengan pintu masuk bangunan atau fasilitas. Dari hasil pengujian yang dilakukan, telah dihasilkan sistem parkir yang dapat memberikan rekomendasi lokasi parkir berdasarkan pengecekan urutan oleh program mikrokontroler. Di setiap lokasi parkir terdapat sensor untuk mendeteksi keberadaan kendaraan. Di bagian pintu masuk, tampilan seven segment memberikan informasi jumlah parkir yang tersedia. Kata kunci: mikrokontroler, rekomendasi lokasi parkir, sensor parkir

Sweep Frequency Response Analysis (SFRA) is a sensitive diagnosis technique to detect and to find out changes in the characteristic of distribution transformer winding by injecting low voltage at the specified frequency range. The changes can be due to electrical damage or mechanical disturbance such as during transportation, earth quake, and short circuit. Disturbances that can be detected are the transformer core damage, winding shift, and deformation of the transformer winding. The SFRA test method being used here is to compare bushing distance which is implemented by the frequency versus magnitude curve. The test is done using D-YN5 distribution transformer with 315 kVA capacity located at PT PLN Kebun Jeruk Area. The test results showed that for normal condition with relative value, the R-LF value is 2.76 > 2, R-MF is 3.89 > 1, R-HF is 1.73 > 0.6 and for mild disruption condition the R-LF value is 0.6 < 0.79 < 1, R-MF is 0.6 < 0.61 < 1, R-HF is 1.03 > 0.6 which meet the reference standard DL/T 911-2004. Keywords: Sweep Frequency Response Analysis, transformer deformation, SFRA testAnalisis Respons Frekuensi Penyapuan atau Sweep Frequency Response Analysis (SFRA) adalah teknik diagnosis yang sensitif untuk mendeteksi atau mengetahui perubahan karakteristik kumparan transformator distribusi dengan menginjeksi tegangan rendah pada rentang frekuensi yang ditentukan. Perubahan karakteristik tersebut dapat disebabkan oleh kerusakan kelistrikan atau gangguan mekanis seperti kerusakan pada saat transportasi pengiriman, gempa bumi, dan hubung singkat. Jenis gangguan yang dapat dideteksi adalah kerusakan pada inti transformator, pergeseran kumparan, dan perubahan bentuk kumparan (deformasi) transformator. Metode pengujian Analisis Respons Frekuensi Penyapuan yang dipergunakan disini adalah dengan melakukan perbandingan antara jarak kaki-kaki antar bushing yang diimplementasikan dalam bentuk kurva hubungan antara frekuensi dan magnitudo. Pengujian dilakukan pada satu jenis transformator distribusi D-YN5 dengan kapasitas daya 315 kVA yang berlokasi di PT PLN Area Kebon Jeruk. Dari hasil pengujian untuk kondisi normal dengan nilai relatif didapat R-LF bernilai 2,76 > 2, R-MF 3,89 > 1, R-HF 1,73 > 0,6 dan untuk kondisi tingkat gangguan ringan didapat R-LF bernilai 0,6 < 0,79 < 1, R-MF 0,6 < 0,61 < 1, R-HF 1,03 > 0,6 yang sesuai dengan acuan standar DL/T 911-2004. Kata kunci: Analisis Respons Frekuensi Penyapuan, deformasi transformator, pengujian SFRA

Abstract Network intrusion detection system is a system that can detect illegal accesses or intrusions happened in a computer network. Actually, there are many types of intrusion detection systems and the differences are based on how network administrators implement the system to secure the network. In this study, the system called Network Intrusion Detection System or NIDS in brief, is used to design and implement the intrusion detection system in the network model design. Intrusion detection system will utilize the snort application that serves as a sensor and detection server and be implemented in a network model that has been designed previously. The performance of the system is investigated through the monitoring of the use of disk space, memory usage and cpu usage of the system during intrusion detection identification process. Three different intrusion scenarios such as Portscanning, ICMP flooding and SYN flooding is performed to see the effect in the system's performance. During the test, the use of disk space still has not shown any significant use, due to the detection time limit used in this study was too short. However, the difference in memory

Abstract Optical fiber transmission is generally used when the channel capacity (40 Gbit / s). Some of the key factors in achieving successful performance of this system include the implementation of Apol-DPSK modulation technique (Alternate Polarization Return-to-Zero Differential Phase Shift Keying), which accurately able to power up the canal, placement of optical amplifier (repeater) is recommended to increase the transmission range (the average gain for the entire wavelength range, low noise figure) and the use of optical fiber characteristics. To complement performance optical gain is selected fiber types NZDSF (Non-Zero Dispersion shifted fiber), it certainly can provide significant gains at the same time to reduce the widening pulse narrowing occurs due to chromatic dispersion and non-linear fiber effects.

Abstract Arrester melindungi peralatan gardu terhadap switching dan gelombang surja. Arrester yang rusak dapat membuat sistem tenaga menjadi kegagalan sehingga menyebabkan sistem seluruhnya mati/padam , atau bahkan meledak merusak peralatan lain atau menyakiti orang. Sebuah pemeliharaan yang prediktif secara efisien membantu menghindari masalah seperti ini pada arrester, menunjukkan kebutuhan untuk substitusi arrester ketika kegagalan permanen terdeteksi. Tulisan ini menyajikan serangkaian tes yang dilakukan untuk menghubungkan gambar termal dan kegagalan yang biasa terjadi dalam arrester Zinc Oxide dan pengembangan dari algoritma komputasi yang didasarkan pada teknik kecerdasan buatan untuk menganalisis gambar thermal pada arrester Keywords: Arrester, Jaringan Saraf tiruan, Kegagalan, Pemantauan, Zinc Oxide, Gambar thermal
