Kualitas air yang perlu diperhatikan dalam pertumbuhan dan kehidupan udang adalah perubahan temperatur, kadar garam, kebutuhan oksigen dan tingkat keasaman atau kandungan pH<em>. </em> Pemantauan secara manual membutuhkan waktu, tenaga dan biaya yang jauh lebih besar karena harus ada petugas yang berkeliling kolam untuk melakukan pengukuran. Dengan <em>Internet of Things</em> (IoT) yang dikembangkan dalam penelitian ini proses monitoring tersebut dapat dilakukan dengan cepat atau <em>realtime</em>. Model yang dikembangkan terdiri dari perangkat <em>node</em> yang dipasang pada setiap kolam dan <em>masterboard</em> untuk pengumpulan data. Sensor yang dipasang pada setiap <em>node</em> adalah sensor salinitas air, sensor pH dan sensor suhu. Nilai salinitas, pH dan suhu selain ditampilkan pada perangkat penampil yang ada pada <em>node</em> juga dikirimkan ke <em>masterboard</em>. Hasil penelitian menunjukkan perangkat sensor bekerja dengan baik, data salinitas air, pH dan suhu dapat ditampilkan pada <em>node</em>. Ujicoba komunikasi data juga dapat berkerja dengan baik yang ditunjukkan dengan data dapat dikirimkan ke <em>masterboard</em> dengan delay 1 detik karena data masuk secara bergantian atau serial. <em>Masterboard</em> dapat bekerja untuk mengirimkan data ke basis data <em>cloud</em> firebase untuk selanjutnya data ditampilkan pada aplikasi monitoring yang telah dikembangkan.</p><p class="Body"> </p><p class="Body"><em><strong>Abstract</strong></em></p><p class="Judul2"><em>Shrimp is one of the leading commodities for Indonesia from the fisheries sector. Shrimp farming, needs to pay attention to pond water quality. The water quality parameter that needs to be considered in the growth and life of shrimp is temperature, salinity, and pH. The farmer usually, monitor the shrimp pond manually that requires much greater time, effort and cost. The process can be automated with the Internet of Things (IoT) developed in this research. The model developed consists of a set of nodes installed in each pond and a masterboard for data collection. The sensors installed at each node are water salinity sensors, pH sensors and temperature sensors. The Salinity, pH and temperature score besides being displayed on the display device at each node, it is also sent to the masterboard through data communication. The results show that the sensor and data communication devices can work well with low latency (1 s) since the data received serially. Masterboard can work to send data to the Firebase cloud database so that the data may displayed in the monitoring application that has been developed.</em></p><p class="Body"><em><strong><br /></strong></em></p>

Shrimp farming with a non-partial harvest system is a cultivation concept to obtain optimal production harvest. The purpose of this study was to determine the business feasibility status of vaname shrimp (L. vannamei) cultivation with a non-partial harvesting system in terms of the ecological and financial aspects from aquaculture. The research method used in this study is a survey research method with data collection techniques based on purposive sampling. The results showed, this non-partial system is ecologically very feasible, because the conditions of the average daily water quality parameter values (DO, pH, temperature, salinity) during the aquaculture period are still above the water quality standard threshold for intensive aquaculture. The business financial feasibility analysis resulted in a profit of IDR 441,307,102,-, BEP Unit 2,062 Kg, BEP Sales IDR 119,995,253,-, R/C of 1.71, Return on Investment of 47.69%, and Payback Period of 2.7 years. Meanwhile based on investment analysis, the Net Present Value of IDR 34,136,139,245,-, Net B/C 11.61, and Internal Rate of Return 37.23%. So, it can be denied, that based on ecological aspects and economic multiplication of aquaculture systems like this can be categorized as very feasible and profitable to be globally developed.

Nine runoff containment basins (RCBs), used directly or indirectly for irrigating plants in ornamental plant nurseries, and one adjacent stream were sampled for water quality between Feb. and July 2013 in Maryland (MD), Mississippi (MS), and Virginia (VA). Triplicate water samples were taken monthly. Analysis was done for 18 water quality variables including nitrate-nitrogen (NO3−-N) and ammonium-nitrogen (NH4+-N), orthophosphate-phosphorus (PO4-P) and total-phosphorus (T-P), potassium, calcium, magnesium, sulfur, aluminum, boron (B), copper (Cu), iron (Fe), manganese, zinc (Zn), pH, total alkalinity (T-Alk), electrical conductivity (EC), and sodium. Additionally, 15 RCBs from 10 nurseries in Alabama (AL), Louisiana (LA), and MS were sampled in 2014 and 2016. Most prevalent correlations (P = 0.01) were between macronutrients, EC, B, Fe, and Zn, but none were prevalent across a majority of RCBs. Water quality parameter values were mostly present at low to preferred levels in all 25 waterways. Macronutrient levels were highest for a RCB that receives fertility from fertigation derived runoff. Water pH ranged from acidic to alkaline (>8). Results of this study show water quality in RCBs can be suitable for promoting plant health in ornamental plant nurseries, but also shows levels will vary between individual RCBs, therefore demonstrates need to verify water quality from individual water sources.

Changes in temperature, pH, and turbidity in concrete fish ponds greatly impact to the fish survival. Initial observations showed that among 3.067 fish seeds, 1.633 fish (53%) died and only 1.434 fish (47%) was successfully harvested. The application of water quality monitoring devices from concrete pools designed based on the Internet of Things technology has been tested. The monitoring equipment will not function optimally without an application that functions to receive monitoring data and then take action. Pool water quality monitoring equipment connected to the cloud using a GSM network connection. The recorded data is then displayed on the water quality monitoring application that designed using the Android operating system. Application design is developed using a User-Centered Design approach, where the design process was carried out by considering several variables: ease for use, clarity of information delivery, the fulfillment of needs, and appearance. Based on the results of the design evaluation, weaknesses can be determined, namely, difficulty to find the search menu for click history data, find the refresh button, read the results of searching for historical data, and read data in tables and graphs. Based on this, further improvements can be made to improve the application being made. The monitoring equipment is expected to provide information to pond managers to immediately take action if changing in pH and temperature beyond the limit so that the fish mortality rate can be minimized.

Mangrove forest is tropical coastal vegetation that grow on muddy and sandy soils which affected by sea tides. One of important commercial species that live in mangrove ecosystem is the mud crab (Scylla serrata). Feed and water quality have been considered as critical components for supporting the growth both of weight and carapace length of this species. This study was conducted from January to February 2017 in the area of ??Ecotourism Kampung Kepiting, Bali. The influence of different natural feed such as Jerbung shrimp (Penaeus merguiensis), Mollusca, lemuru fish (Sardinella lemuru) and sea worms (Nereis sp.) on the growth performance of the mud crab were investigated. Water quality parameter data such as pH, DO, temperature, salinity and ammonium were also collected. The obtained data were analyzed by using variance analysis of Statistical Product and Service Solutions (SPSS) version 21. The result showed that the use of different types of feed have no effect on  the length of carapace, but it has significantly influence on  the specific growth rate of mud crab. Finally, different types of the given feeding were still resulted in the save range of water quality parameters for mud crab culture.

Abstract: The most common buzzwords in the world is “The Internet of things” (IoT) and IOT describes the network of physical objects, so known as, "things" those are rooted with sensors in the devices, application software, technologies that is used for the resolution of connecting one end to another end and exchanging information with other devices and systems over the Internet. The IoT 5G technologies can also be used in journalism and the primary focus is to increase M2M interaction of mass communication devices. One way it is “ubiquitous computing” can occur using any device, in any location, and in any format. The Internet of Things (IoT) is all about small cost sensors grabbing data to communicate with one device to another device using cloud solutions. Coming to the 5th generation mobile network. We have already started using 4G networks and as we know that, start with 1G, 2G, 3G, and 4G networks. The 5th generation network is going to enable an upcoming new network that will associate virtually every person globally connected and everything organized including IoT devices, objects and machines. Central communication and Journalism is the activity of gathering right information, evaluating, generating, and presenting broadcast information. It is high time to start using IOT Technology using 5th generation high-speed network connectivity devices to communicate or data transfer in the area of journalism. Keywords: IOT – Internet Of Things, 5G- Fifth Generation in data network, JMC – Journalism and Mass Communications, M2M – Machine to Machine, Cloud , Artificial intelligence and Machine Learning.
