Intensive shrimp farms need mangroves to increase the carrying capacity of their waters. Every 1 Ha of intensive shrimp pond requires 7.2 Ha mangrove to absorb nitrogen (N) and 21,7 Ha to absorb phosphor (P) from waste water disposal. This study was conducted to estimate the extent of lmangrove required to absorb nitrogen (N) and phosphorus (P) wastes removed from intensive shrimp farming in Banyuputih Subdistrict of Situbondo Regency. From the field survey results obtained data on the area of ​​productive intensive ponds in the District Banyuputih is 39 Ha. The result of data analysis indicate that 280,3 Ha mangrove is needed to support the absorption of nitrogen (N) and 846,3 Ha mangrove to absorb phosphorus (P) of effectiveness pond waste pond in the study area. The mangrove in this subdistrict of Banyuputih (540,18 Ha) still support in the absorption of nitrogen waste (N), but for the absorption of phosphorus posfor (P) ponds still needed reforestation of at least 304,12 Ha from the existing mangrove area. If the local government intends to develop intensive shrimp ponds in accordance with the carrying capacity or maximum capacity of coastal waters of Banyuputih in decomposing 58 ha of tambak organic ponds, the current mangrove condition (540.18 Ha) still supports the absorption of nitrogen (N) from ponds intensively covering an area of ​​58 Ha, but to absorb the posfor (P) lagoon is still needed addition (reforestation) of 718.42 Ha.

AbstrakPesisir Kulon Progo saat ini memiliki habitat mangrove dan lahan tambak udang. Perkembangan salah satunya, akan mengakibatkan berkurangnya luas lahan yang lain. Penelitian ini bertujuan untuk (1) menganalisis kondisi fisik wilayah pesisir Kulon Progo, (2) menentukan zona yang sesuai untuk kawasan mangrove dan/atau tambak udang di wilayah pesisir Kulon Progo, dan (3) menyusun rekomendasi pengelolaan kawasan mangrove dan atau tambak udang di wilayah pesisir Kulon Progo. Pengambilan sampel dilakukan dengan purposive sampling. Data kondisi fisik lahan diperoleh melalui observasi dan pengukuran di lapangan. Zonasi kawasan mangrove dan tambak udang dilakukan dengan reinterpretasi peta dan metode matching dengan parameter kesesuaian yang telah ditentukan sebelumnya. Strategi pengelolaan kawasan mangrove dan tambak udang dilakukan dengan menganalisis faktor internal dan eksternal wilayah menggunakan analisis SWOT. Hasil penelitian menunjukkan bahwa kondisi fisik wilayah pesisir Kulon Progo terdiri atas substrat dasar berbatu, lempung bergeluh, lempung, lempung berpasir, berpasir. Pasang surut air laut berkisar 1-1,1m, salinitas air antara 0-29‰, kecerahan air antara 0 cm - tidak terukur, dan suhu air  antara 27-34,1 °C. Kondisi fisik pesisir Kulon Progo ada yang sesuai (S2) untuk pertumbuhan mangrove dan tambak udang, serta ada yang tidak sesuai untuk keduanya. Zona yang sesuai (S2) untuk kawasan mangrove terdapat di muara Sungai Bogowonto seluas 1,58ha. Zona yang sesuai (S2) untuk kawasan tambak udang seluas 134,49ha. Strategi pengelolaan kawasan untuk zonasi mangrove di lokasi kajian yang dapat direkomendasikan dalam penelitian ini antara lain (1) pelestarian dan pengembangan kawasan mangrove dalam bentuk kawasan konservasi sekaligus sebagai objek wisata dan pendidikan, (2) mengembangkan dan meningkatkan komitmen masyarakat atas arti penting kawasan mangrove untuk menghambat alih fungsi kawasan mangrove, (3) mengembangkan zona mangrove dengan menanam jenis mangrove yang sesuai dengan kondisi fisik lahan, (4) melakukan tindakan persuasif dalam mewujudkan konsensus masyarakat untuk membentuk kawasan lindung mangrovAbstractThe Coast of Kulon Progo is currently the habitats for mangroves and shrimp ponds, i.e., where the development of the former reduces the latter. This research aimed to (1) analyze the physical condition of the coast, (2) determine the suitable zone for mangrove areas and/or shrimp ponds along the coast, and (3) propose a recommendation for mangrove and/or shrimp pond management along the coast. The samples were selected using purposive sampling technique. The research also employed field observation and measurement to acquire the physical condition of the land. The zonation of mangrove area and shrimp pond was obtained from map reinterpretation and matching technique with the predefined parameters of land suitability. As for the mangrove and shrimp pond management strategies, the research used SWOT analysis to study both of the internal and external factors in the study area. The results showed that the substrate of the coast was composed of rock, clay loam, clay, sandy clay, and sand. Aside from the substrate, the physical condition of the coast was characterized by sea tide (1-1.1 m), salinity (0-29%), water transparency (0 cm-undetectable), and temperature (27-34.1°C). These characteristics classified the coast into two types of suitability for mangrove growth and shrimp pond development, namely suitable (S2) and unsuitable. While the suitable (S2) zone for mangrove development occupied 1.58 ha area in the mouth of Bogowonto River, the suitable (S2) zone for shrimp pond was considerably larger, i.e., 134.49 ha. The recommended strategies for mangrove zone management in the study area are as follows: (1) mangrove preservation and development as a conservation area and an object for tourist destination and education, (2) the encouragement and improvement of community’s commitment to accentuating the essential functions of mangrove areas and to decelerating any land use conversions of mangrove zone, (3) the development of mangrove zone by planting suitable mangrove species with the physical condition of the area,  and (4) the implementation of persuasive actions in actualizing community consensus on mangrove area development.

Shrimp Production

The largest utilization of coastal areas in Brebes Regency is the shrimp farming ponds. Shrimp volume statistics until 2016 showed that shrimp production in Brebes tends to decrease. The decrease in shrimp production can be caused by disruption in the environmental quality from the surrounding activities. This study aims to analyze the causes of declining production based on the quality of the physical environment of shrimp ponds. The variables used are water quality values (Ph, Tds / Ec, and salino), vegetation values of ponds, and waste disposal values around ponds <1000m, 1000-2000m,> 2000m. The data used is a Quick Bird image as of 2015 to determine the area of shrimp ponds and results of field survey in February 2018 for water quality sampling and observation. The analytical method that is used is scoring and weighting. The grades of pond environment quality that are produced are Poor; Good; and Well. The results show that the subdistricts of Brebes and Wanasari have well environmental quality; Tanjung has good environmental quality; and environmental value of Bulakamba and Losari subdistricts have poor environmental quality. Environmental quality is strongly influenced by industrial activities, onion farming activities, and settlements. This environmental quality study can be utilized for the management of sustainable shrimp farming.

In recent years, shrimp farming has developed rapidly and become one of the major export sectors of Vietnam. In particular, Mekong Delta Vietnam (MDVN) accounts for over 90 % shrimp farming area in Vietnam. Shrimp industry development leads to use a large amount of antibiotics (ABs) and pesticides for disease prevention, treatment and sanitation pond. These compounds are usually discharged directly into the environment through water and sludge after harvesting. The presence of antibiotics and pesticides in the environment cause negative impacts on ecosystems and human health. In this study, the passive sampling method with POCIS sampler (Polar Organic Chemical Integrative Samplers) was used to monitor the presence of 12 ABs and 2 pesticides in water of intensive shrimp ponds and the surrounding canals at Tan Tru District (Long An province) and Can Gio District (Ho Chi Minh city) following a production cycle. The results showed that ABs and pesticides were detected in water and sediment in the pond and canals in both research sites. Two pesticides (atrazine and diuron) were detected in the pond and leading canals in both study areas with low concentrations from several ng/L to several tens of ng/L. In Tan Tru, three antibiotics (Trimethoprim, Sulfamethoxazole and Enrofloxacin) were detected in water at concentrations ranging from several tens of ng/L to 300 ng/L; in sediments of shrimp pond and canal the levels of pesticides and ABs ranged from 10 to 200 µg/kg. In Can Gio - HCMC, 4 ABs (Trimethoprim, Sulfamethoxazole, Ciprofloxacin and Enrofloxacin) were detected ranging from a few ng/L to several µg/L in water, and a few mg/kg in sediments of the pond. The results also showed that in the pond, ABs type and concentration detection varied by region and shrimp growth cycles.

Abstract. Afsholnissa S, Hernawan E, Lastini T. 2019. Land cover change and land use suitability analyses of coastal area in Bantul District, Yogyakarta, Indonesia. Biodiversitas 20: 1475-1481. Shrimp farming in the southern coast of Bantul District is considered to be the cause of environmental degradation, decline of mangrove association due to logging for land conversion to shrimp pond and also considered to be the cause of agricultural land for crops around the shrimp pond. The purpose of this study was to identify land use change and analyze the land suitability for shrimp farming, agriculture, and mangrove plant associations. Identification of land use was done using ENVI 5.3. The study identified 34.88 ha (3.16%) empty ponds, 20.97 ha (1.90%) active ponds and as much as 91.93 ha (8.31%) land used for agriculture. The identification of land use change using Google Timelapse revealed a dominant land conversion of sandy soil and mangrove plant area into shrimp ponds in 2007 and continue to increase from 2011 to 2015. Land suitability was evaluated using ArcGIS 10.5 with an overlay method. The results revealed that 634.82 ha area of the land was suitable for shrimp ponds and ​​84.32 ha area were suitable for non-paddy agriculture. Lands suitable for paddy field were about 148.58 ha, and that for mangrove plant association was 616.42 ha. Spatially, coastal area of ​​Bantul District was dominantly suitable for shrimp farming.

Abstract The shrimp culture industry around Chilika Lake has expanded in the last two decades under the rationale of providing economic benefits at national, regional, community and household levels. Salinisation and pollution of agricultural land especially rice paddies by seepage usually ruin crops and render the land unsuitable for agriculture. As a result there is the decline in the yield rate, which led to the conversion of agricultural land to shrimp ponds. After the shrimp culture for some years the land will be unable to support any natural or agricultural productivity. In due course, these shrimp ponds are abandoned being fit for nothing. The lack of emphasis on enforcement of different legislation, particularly environmental legislation, has allowed the shrimp farms to operate in and around the lake using culture practices that degrade the environment. Thus, the problem with the state is not a lack of legislation, but an unwillingness or inability to enforce it. As a result of this, an established livelihood system is broken down as land with multiple agricultural uses is turned over to mono-crop production. This in turn will lead to abandoned land, which is of no use after few years.

Two Phases

The purpose of this study is to reuse shrimp pond bottom sludge for industrial-scale organic fertilizer production, to reduce emissions from shrimp farming, and protect the environment. Sludge from the bottom of shrimp ponds is collected through channel settling with a filter net of 0.25 millimeters in size, rainwater is used to wash the salt content in the sludge of shrimp ponds. When the EC (Electrical Conductivity) of the sludge drops below 4 mS / cm, the sludge is mixed with dry straw at the rate of 1 ton of sludge with 250 kg of straw. The products of this rice straw and sludge mixing process are bio-fermented in two phases including anaerobic phase and aerobic phase. The results showed that the sludge-based fertilizers meet national technical regulation QCVN 01- 189: 2019/BNNPTNT. Of quality parameters, total organic carbon, macronutrients (N, P2O5, K2O), trace metals (Zn, Cu), and other heavy metals (Pb, Cd) are within the regulation limits. The paper also shows the potential of reusing shrimp pond bottom sludge for industrial-scale organic fertilizer production, with the possibility of utilizing nutrients contained in the sludge supplied to crops, especially reducing environmental pollution from intensive shrimp farming.
