AbstrakKeamanan server merupakan hal penting yang perlu diberikan perhatian lebih saat melakukan konfigurasi server. Pada umumnya serangan yang terjadi pada server diketahui setelah terjadinya kegagalan pada server dalam memberikan layanan. Pada penelitian ini, dibangun sebuah sistem keamanan server yang dapat melakukan monitoring pada sebuah server ketika terdeteksi adanya aktivitas yang tidak wajar. Pemberitahuan akan dikirimkan melalui SMS (Short Message Service) ke handphone Administrator jaringan. Sistem yang dibangun melakukan pendeteksian intrusi pada server secara realtime menggunakan SNORT. Ketika terjadi akses yang tidak wajar pada server, maka SNORT akan mendeteksi dan mengirimkan informasi terjadinya aktivitas yang tidak wajar ke Administrator jaringan. Sistem ini diujikan dengan lima jenis serangan yakni PING Attack, DoS/DDoS Attack, Port Scanning, Telnet Access dan FTP Access. Parameter yang diamati pada penelitian ini adalah beban aktivitas yang terjadi pada sumber daya server meliputi CPU, Memory (RAM) dan beban jaringan. Hasil penelitian menunjukkan bahwa saat terjadi upaya serangan terhadap server, SNORT dapat menghasilkan alert yang akan disimpan pada log sekaligus dikirimkan ke handphone Administrator melalui SMS. AbstractServer security is an important thing that needs to be given more attention when configuring a server. In general, attacks that occur on the server are known after a failure on the server in providing services. In this study, a server security system was built that could monitor a server when an unusual activity was detected. Notifications will be sent via SMS (Short Message Service) to the network Administrator's smartphone. The system is built to detect intrusions on the server in real time using SNORT. When improper access occurs on the server, SNORT will detect and send information about the occurrence of unusual activity to the network Administrator. This system is tested with five types of attacks namely PING Attack, DoS / DDoS Attack, Port Scanning, Telnet Access and FTP Access. The parameters observed in this study are the activity load that occurs on server resources including CPU, Memory (RAM) and network load. The results showed that when an attempt was made to attack the server, SNORT could produce alerts that would be stored in a log as well as sent to the Administrator's smartphone via SMS.

The equipments in computer rooms are complicated in nature. Many factors may influence their normal operations, for example: voltage, temperature, humidity, and the normalcy of systems. It would be prudent to have a monitoring system to prevent from unpredictable problems. Most monitoring systems in the market can only issue alarms in abnormal situations and then analyze the aftermath. They are also expansive and lack the ability for distant instant control. To tackle this problem, after our successful and practical experiments, we utilize GSM text messaging ability (i.e. SMS, short message service) and make distant monitoring possible. The monitoring system is established with a reasonable price that is well below current market. With this system, the manager/administrator can monitor the real-time status of equipments in computer rooms, send control commands through SMS and then get them executed to solve the problems instantly and effectively.

Accordingly, this robot is sending the vision to android smartphone in real time. Therefore, the owner of the house or the flat can see inside the house while they were not around. The objective of this research is to develop autonomous robotic to be able to monitor the area from the existing of human and animal and send the vision to android smartphone in real time. This research used four leg robotic as an autonomous robotic monitoring. Four leg robotic is equipped with camera which connected to router based on wireless connection, PIR and ultrasonic sensor and GSM module to send short message service (SMS) notification if PIR sensor detect some movement. The experiment used cat as an animal object. Experiment showed that this robot can follow the object, either a human or an animal, within range of 10–45 cm from robot in 12 seconds and send the vision to android smartphone in real-time. The SMS is received in 5 seconds after camera capture the object. This robotic cannot determine who is the object on the camera because it is not equipped with object detection system.

ABSTRACT The slow handling of the flooding problem for people who live on riverbanks and densely populated areas in urban areas due to the lack of preliminary information obtained by the local community, causing huge losses both morally, materially and even causing fatalities. Based on these problems, a prototype monitoring system for flooding early detection was made with the aim that it can be used as a means of information whose data can be accessed through notifications in the form of short message services (SMS) in real time. In making this research, data collection was carried out in the form of water level data that had occurred at the location of the flood and then made the system design and implementation of that system by conducting trials in the field. This early flood detection system works by monitoring the water level using a level control system. This water level monitoring uses an ultrasonic sensor that is controlled using an arduino uno microcontroller. Data information about the water level is forwarded to the GSM module in the form of a notification message of SMS to the public. For the working of this prototype device in the design, the author uses an electrical power supply from renewable energy in the form of On Grid PLTS system. The results obtained from this research are for normal status the water level is at 5-50 cm, for alert status is 55-85 cm and for danger status is 90-100 cm. Keywords:   Water Level, Ultrasonic Sensor, Arduino Uno Microcontroller, GSM Module, On Grid PLTS System   ABSTRAK Lambatnya penanganan masalah banjir bagi masyarakat yang tinggal di daerah bantaran pinggiran sungai maupun kawasan padat penduduk yang berada di perkotaan dikarenakan kurangnya informasi awal yang diperoleh oleh masyarakat setempat sehingga menyebabkan kerugian yang sangat besar baik secara moril, materil bahkan sampai menimbulkan korban jiwa. Berdasarkan permasalahan tersebut maka dibuat suatu prototype sistem monitoring pendeteksi dini banjir dengan tujuan dapat digunakan sebagai sarana informasi yang datanya dapat diakses melalui notifikasi berupa short message service (SMS) secara real time. Dalam membuat penelitian ini dilakukan pengumpulan data berupa data level ketinggian air yang pernah terjadi di lokasi banjir kemudian membuat perancangan sistem serta pengimplementasian dari sistem yang dibuat dengan melakukan uji coba di lapangan. Sistem pendeteksi dini banjir ini bekerja dengan cara memantau level ketinggian air menggunakan sistem level control. Pemantauan level ketinggian air ini menggunakan sensor ultrasonik yang dikontrol menggunakan mikrokontroller arduino uno. Informasi berupa data-data mengenai level ketinggian air ini diteruskan ke modul GSM berupa pesan notifikasi dalam bentuk SMS kepada masyarakat. Untuk bekerjanya perangkat prototype ini dalam rancangannya penulis menggunakan suplai daya listrik dari renewable energy berupa sistem PLTS On Grid. Hasil yang diperoleh dari penelitian ini yaitu bahwa untuk status normal level ketinggian air berada pada angka 5-50 cm, untuk status siaga berada pada angka  55-85 cm dan untuk status bahaya berada pada angka 90-100 cm.

Point Positioning

Real-time precise point positioning (RTPPP) is a popular positioning method that uses a real-time service (RTS) product to mitigate various Global Navigation Satellite Systems (GNSS) errors. However, communication links are not available in the ocean. The use of a communication satellite for data transmission is so expensive that normal users could not afford it. The BeiDou short-message service provides an efficient option for data transmission at sea, with an annual fee of approximately 160 USD. To perform RTPPP using BeiDou short messages, the following two challenges should be appropriately addressed: the maximum size of each BeiDou message is 78 bytes, and the communication frequency is limited to once a minute. We simplify the content of RTS data to minimize the required bandwidth. Moreover, the orbit and clock corrections are predicted based on minute-interval RTS orbital and clock corrections. An experiment was conducted to test the performance of the proposed method. The numerical results show that the three-dimensional positioning precision can reach approximately 0.4 m with combined GPS + GLONASS and approximately 0.2 m with combined GPS + GLONASS + Galileo + BeiDou.

Gardu distribusi merupakan komponen utama dari sistem distribusi tenaga listrik. PLN sebagai penyedia kebutuhan listrik di Indonesia masih menggunakan cara konvensional dalam memonitor arus beban pada gardu distribusi dengan datang ke lokasi dan mengambil data. Rancang bangun sistem monitoring arus beban pada gardu distribusi menggunakan SMS merupakan perangkat yang diintegerasikan pada gardu distribusi. Nilai arus beban yang dibaca dan dikonversi oleh sensor, informasi waktu dan tanggal secara real time ditampilkan pada LCD. Pengimplementasian sistem monitoring arus beban dilakukan pada gardu distribusi KA-0298 yang menyuplai Laboratorium Teknik Elektro Universitas Udayana. Perangkat ini dapat melakukan monitoring arus beban berdasarkan perintah yang dikirimkan melalui SMS. Perintah SMS yang dikirim dengan kode “CEKARUS” dapat diterima dan direspon oleh sistem monitoring arus beban dengan hasil balasan SMS informasi nilai arus beban fasa R, fasa S, fasa T dan fasa N pada gardu distribusi. Sistem data logger pada perangkat dapat digunakan untuk merekam perubahan arus beban pada gardu distribusi. Sistem notifikasi arus beban memberikan SMS peringatan jika terjadi gangguan arus beban pada gardu distribusi. [Turnitin Chek 7% 24032017]
