    The big water bodies covering about 4.3 metres hectare of inland water and 480 km of coastline give very high potential for fisheries and aquaculture production, the subtropical climate and adequate soil and aquatic conditions. Despite this, the development of fish remained very poor and stagnant until 1985. Owing to a lack of funding for science, the few development projects introduced at the time did not achieve the desired results. Consequently , the second and third five year plans did not meet the production goals stated. On the other hand, in 1984 the FRI was developed and improved aquaculture and management practises were subsequently produced, and a positive contribution was made to almost reaching the production target of 1.2 m tonnes, in 1994-95, the final year of the Fourth Five Year Plan.The aquaculture sector in India is a rapidly growing, more than 7 per cent, fish farming sector annually. About 95% of total annual aquaculture production of 5.77 million tonnes is supported by Freshwater Aquaculture. The three main Indian carps (CatlaCatla, Labeorohita and Cirrhinusmrigala) and their "composite carp culture" technologies have brought substantial upward shifts in freshwater development with the inclusion of the exotic three carp (Hypophthalmichthysmolitrix, Ctenopharyngodonidella, Cyprinus carpio) in ponds and tanks. Late in the day, diversification took place by the introduction of medium and minor carps, catfish and murrels.

    Microplastics are plastic fragments with size less than 5mm in length, according to the U.S. National Oceanic and Atmospheric Administration (NOAA). Microplastics occur and spread in the environment as a result of plastic pollution. Although further assessment is needed to find the health impact of microplastic exposure to humans, several studies show that microplastic might harm the ocean and aquatic life. Code river is one of the big rivers in Yogyakarta. According to the Regional Environmental Agency of Yogyakarta, Code river was highly polluted by domestic waste and wastewater from the settlement along the river and its tributaries. Therefore, the objectives of this research are to investigate the abundance and characteristic of microplastics in fish from Code River Yogyakarta. Fish samples were collected from the fisherman in the upstream, middle, and downstream areas of Code River from February to May 2019. In the laboratory, the samples were analyzed using Wet Peroxide Oxidation (WPO) method. Fish gills and intestine were oxidized using WPO method followed by density separation for 24 hours. Nikon SMZ445 Stereoscopic Microscope with 35x magnification was used to analyze the shape, color, and total of microplastics. The highest abundance was found in fish samples collected from the upstream area (4.33 particles/gram) compare with the downstream area (3.25 particles/gram). The dominant color is blue, while the dominant type of microplastics is fiber.

    This study aims to determine the biological aspects of snakehead fish, kerandang fish, fish and kapar fish caught in the Sebagau river and the economic benefits for fishermen. Analysis of the relationship between length and weight of fish showed a close relationship between fish length and weight with a positive allometric growth pattern. The results of the analysis of fish stomach contents to determine fish food habits showed that the dominant food types were fish fry for Kehung fish 87%, Kerandang 95% and Gabus 99%. Meanwhile, for kapar fish, food dominates in the form of plants 72%. The fishing ground along the Sebangau watershed is in a tributary that is directly connected to the Sebangau river. Economically, the fish catch in the Sebangau river by fishermen is sufficient to fulfill family life.

    This paper describes the design of a robot for collecting waste floating on the water surface. Three important issues for designing the aquatic robots are a cost-effective solution along with robustness and durability. Due to the nature of the cleaning work, we designed the robot structure with car like mechanism that can provide high stability, good ability in maneuver and can easily collect all the waste flowing on the water. The plastic pipe container works best for this case and fulfils all structural stability criteria. For collection of waste, a motor-driven conveyor belt has been designed for collecting the wastes and deploy it into a plastic box connected to the platform. This design provides simple and effective waste removal and accommodates large amounts of waste within a little space. This light-weight and tough structure support the total weight of the collected waste, conveyor as well as the hardware components used. The rotating arms system based a differential drive mechanism has been designed, which allows the robots to require a 360 turn on the spot and provides high thrust. Electronic circuit and motors have been placed on the platform, in order to protect them from water. The robot is automatically controlled by Arduino, sensors, motor driver, GPS and GSM modules. The testing of the robot prototype proved to be effective in waste collecting and getting back to the way-point. The maximum trash loads that robot can bear is up 5 kg. The main aim of the project is to optimize time, energy and overall process speed.

    The more technology develops, the more it creates a consumptive society pattern. Apart from shopping, the shipping sector has also experienced many developments. PD. Masterindo Laju Abadi provides shipping and quarantine services for fish shipments, where each fish sent must have a quarantine document in order to be sent. However, the management of shipping data and tracking of receipts is still done manually, causing several errors in data retrieval or in calculating bills. If this condition is allowed to drag on, then the hope to increase the company's productivity cannot be fulfilled and it is more difficult to achieve, therefore it is better if this service sector is supported by existing technology, so that it can make it easier for fish sellers to run their business. This research takes the theme of the business that is carried out by PD. Masterindo Laju Abadi, a shipping service company that collaborates with JNE and Caratina which only provides a few employees in the office division to handle a variety of different jobs, therefore it would be better if a job done by these few people can be handled properly and efficient.

    HighlightThe main facilities in Cilacap oceanic fishing port were identified and analyzed.Provide crucial information for the managers of the Cilacap oceanic fishing port with regards to developing the facilities.The predictions for the production of capture fisheries until 2027 in Cilacap oceanic fishing port have been analyzed to give the information to develop facilities capacity of the fishing port.AbstractFishing ports are an important factor in supporting various capture fisheries activ- ities in Indonesia. The number of vessels that landed fish at Oceanic Fishing Port (PPS) Cilacap during 2005-2013 increased by an average of 1.33% annually, which has implications for port capacity. It is important to know the capacity requirements for the basic facilities of the dock, and port pond at PPS, therefore that the activity of landing fish catches can take place properly. The purpose of this research is to not only get an overview of the current condition, and capacity of the main facil- ities at PPS Cilacap, but also to predict the production of fish caught until 2027. The research method is a case study. The data used in this study are primary, and secondary data obtained from PPS Cilacap. The results showed that the length of the landing dock in 2016 was 648.8m with the area, and depth of the port pool of 155,000 m2 and -2.5 m. The predicted requirement for the length of the landing dock until 2027 is 1,380.1 m, with the area and depth of the harbor pool of 239,612 m2 and -4.1 m. Based on the results, it shows that PPS Cilacap requires additional capacity of the dock, and port pool. Predictions of fish catch in 2022, and 2027 are 20,104,259 tons and 25,407,506 tons.

    This paper seeks to interpret that which is blue of Indonesia—the largest archipelagic nation in the world—by way of proffering for Indonesian Christianity a range of blue hues (corak biru) following an ecotheological perspective. I start by discussing ecotheology and its contribution within Christianity to illustrate how this sub-discipline becomes a “brush” that for Christianity can render such blue hues. This is followed by a discussion on why and how a responsive ecotheology to the environmental/marine ecosystem crisis could render as “blue paint” for that subdisciplinary brush—a blue ecotheology (ekoteologi biru). To accomplish this, both Christianity's abject appraisal of the sea, as well as Christianity's own blue-hued anthropocentrism (corak biru antroposentrisme), are parsed and addressed in turn by the paradigm of a community of creation as “sketch.” These discussions summarily affirm the conviction that the sea must be considered and treated not as an object of human exploitation but as a proper subject working to support the life that is common among all of God's animate creation. Humankind and the sea itself, alike, participate in that life. The spectrum of blueness I propose to be displayed across the “canvas” of Indonesian Christianity is this: to be sea-friendly in both outlook and attitude, in ways that safeguard the sea's ongoing involvement in life. To conclude, this paper invites Indonesian Christianity to put the full array of its blue hues on display within both theological discourse and its activities as the church.

    Title (Bahasa Indonesia):Kontaminasi merkuri (Hg) di Teluk Manado, Sulawesi Utara, IndonesiaArtisanal gold minings, which are situated in the highlands of the northern part of Sulawesi Island,use mercury (Hg) to extract gold and dischargetheirs tailings into rivers; one of the rivers(Bailang River) is connected to Manado Bay. This could cause Hg contamination into the bay. This study aimed to assess the contamination of Hg in the aquatic ecosystem of the bay. For the assessment, the bay was divided into 2 parts, namely the North and the South, and the contamination was assessed by measuring the total Hg concentration in sediments and fishes. Determination of Hg concentration refers to the Indonesian National Standard (SNI) 01-2896-1992 and Guidance of Balai Riset dan Standarisasi Industri Manado. The results showed that the range of Hg concentrations in fish varied by species; in the northern part of the bay: Holocentridae (0.1144-0.1151 ppm), Siganidae (0.0020-0.0034 ppm), Apogonidae (0.0461-0.050 ppm), and Nemipterus (0.0142-0.0144 ppm ). While in the southern part of the bay: Holocentridae (0.1090-0.1104 ppm), Siganidae (0.160-0.164 ppm), Apogonidae (0.1280-0.1291 ppm), Nemipterus (0.0522-0.0530 ppm) , and Priacanthus sp. (0.0194-0.0210 ppm). The average concentration of Hg in sediments of the bay around river mouths varied based on location, i.e. Bailang River was 0.0502 ppm, Sario River was 0.0270 ppm, Bahu River was 0.0615 ppm, and Malalayang River was 0.0143 ppm.Pertambangan emas rakyat menggunakan merkuri (Hg), yang berada di daerah dataran tinggi bagian Utara Pulau Sulawesi, membuang limbah tailing ke sungai menuju ke laut; satu dari sungai tersebut (Sungai Bailang) bermuara ke Teluk Manado. Hal ini dapat menyebabkan kontaminasi Hg ke lingkungan perairan teluk. Penelitian ini bertujuan untuk menilai kontaminasi Hg di ekosistem perairan teluk tersebut. Untuk penilaian, perairan teluk dibagi 2 bagian, yaitu bagian Utara dan Selatan, dan kontaminasi dinilai dengan cara mengukur konsentrasi Hg total pada sedimen dan ikan. Penentuan konsentrasi Hg mengacu Standar Nasional Indonesia (SNI) 01-2896-1992 dan Panduan Balai Riset dan Standarisasi Industri Manado. Hasil penelitian menunjukkan, bahwa kisaran konsentrasi Hg dalam ikan bervariasi berdasarkan jenis; dibagian Utara teluk: Holocentridae(0,1144-0,1151 ppm), Siganidae (0,0020-0,0034 ppm), Apogonidae (0,0461-0,050 ppm), dan Nemipterus (0,0142-0,0144 ppm).Sedangkandi perairan bagian Selatan teluk: Holocentridae (0,1090-0,1104 ppm), Siganidae (0,160-0,164 ppm), Apogonidae (0,1280-0,1291 ppm), Nemipterus (0,0522-0,0530 ppm),dan Priacanthus sp.(0,0194-0,0210 ppm). Konsentrasi rata-rata Hg di sedimen perairan teluk sekitar muara Sungai Bailang sebesar 0,0502 ppm, muara Sungai Sario sebesar 0,0270 ppm, muara Sungai Bahu sebesar 0,0615 ppm, dan muara Sungai Malalayang sebesar 0,0143 ppm.
