In this paper, development progress of a long-range radio communication-based fishing assistant system called e-Nelayan is reported. The purpose of the system is to increase the productivity, safety, and welfare of fishermen using mobile phone and long-range radio based system that enables them to report maritime violations, access and exchange information regarding weather, fishing area, and marketplace, as well as communicate with mainland using Android-based mobile phone within extended range. We used LoRaWAN as a base technology for long-range communication scheme. In this work, the test conducted to obtain an insight to e-Nelayan device (LoRa-based) received RSSI and its packet loss. The received data collected in a server also includes the GPS tracking data. The test results show that our system can reach about 5 km of distance between end-node to the LoRa Gateway within urban area (LoS configuration) and about 2 km for NLOS configuration.

“…The web server and client section were adequately tested, with each menu observed to function appropriately [10]. The integration of the entire system was also carried out by involving the client and server sections (BMKG-KKP to the E-Fishermen server).…”

“…The system also contains three components, divided into two 'sides' based on the user activities, i.e., (i) a mobile application (e-Nelayan Apps version 1.0) installed on an e-Nelayan device (LoRa radio) to be used by "clients" (fishermen), and (ii) a web application acting as a "server" to be used by an administrator assigned by policymakers and law enforcement personnel. The design of the mobile application and the LoRa radio were elaborated in [8]- [10], with the structure, implementation, and evaluation of web application part being more highlighted in this present study. In the fishery sector, the report on ICT application is still an interesting and open analysis area in Indonesia, especially for small boat fishermen [11], [12].…”

<p>This paper presents a webserver for Indonesian fishermen, to support fishing activities. This is one of the sub-systems of e-Nelayan (in English: eFisherman) architecture, which was connected to e-Nelayan Apps; it helps to provide interaction between two users, including the administrators and fishermen. Using hypertext preprocessor (PHP) language, the website was developed to function on an Apache web server, with the adaptation of my structured query language (MySQL) framework for the database. This system was subsequently divided into two parts: (1) the front-end, which is responsible for the accessibility of data collection and (2) the back-end, where administrators update or modify crucial information: price, fishing result, illegal activity report, save our ship! (SOS) potential fish zone, and ship tracking. The administrators are unable to update the real-time weather information for the front-end part. The application was found to record the information obtained from the fishermen through the e-Nelayan apps and meteorology, climatology, and geophysical agency (BMKG in Indonesian). This web system is expected to carry out the following functions: to ensure easier interactions between fishermen and administrators, to enable easy update of information, to promote monitoring and recording of results, and to ensure fishermen’s safety.</p>

“…This is, in particular, the case in small low-frequency devices with an expected larger communication range, e.g. [3] [8]. To determine the best antenna bandwidth, we use the stored energy Q-factor [9], which is known to provide an accurate estimation of the bandwidth for electrically small antennas [10], [11], see also [12][13][14] for periodic structures.…”

In this paper, we determine the physical limitations on the best possible bandwidth as a function of embedded position of the antenna in a terminal for a range of frequencies, and express it as recommendations for antenna design. We furthermore design several antennas and compare their performance with the physical bounds. We manufacture and measure two of these antennas. We show how the bound-design-measure sequence can produce essentially optimal bandwidth antennas. We study how the antenna efficiency change with embedded position. The optimal current inspired a FIFA-like antenna that have a very good efficiency over the considered positions. 2) What is the novelty of your work over the existing work? (limited to 100 words). We show how Q-factor bounds can be used to determine the optimal bandwidth positions for antennas, which is a novel approach to understanding possible design limitations. We also construct an essentially bandwidth optimal embedded antenna, which is interesting in it self. We show that few-parameter geometry antennas can come very close to the optimal behavior for embedded antenna, a fact that has not been shown before. 3) Provide up to three references, published or under review, (journal papers, conference papers, technical reports, etc.) done by the authors/coauthors that are closest to the present work. Upload them as supporting documents if they are under review or not available in the public domain. Enter N.A. if it is not applicable.
