Herawati VE, Hartoko A, Suminto. 2012. The suitability of Segara Anakan waters, Cilacap, Central Java as cultivation area of Polymesoda erosa based on primary productivity using satellite image. Bonorowo Wetlands 2: 41-51. Segara Anakan waters, Cilacap, Central Java is a natural habitat of totok shells (Polymesoda erosa) of high economic value, however, the sustainability of these protein sources is threatened due to habitat degradation and over-harvesting. This study aims to (i) analyze the suitability of Segara Anakan Lagoon to cultivate the toktok shells, as a conservation effort, based on the aspect of primary productivity and chlorophyll-a; (ii) to analyze the suitability of Segara Anakan waters to cultivate the toktok shells based on field data and SPOT satellite image data, ie chlorophyll a, water surface temperature, total suspended solid, pH, dissolved oxygen, salinity, as well as nitrate and phosphate content. The basic concept of this research is combining SPOT satellite image analysis and direct field measurement of some primary productivity parameters in Segara Anakan waters to know the suitability for thokthok shells cultivation. Based on scoring and suitability level, stations 1 and 3 (in the western estuary of Segara Anakan lagoon) are " Suitable on condition" (Sesuai Bersyarat) for the cultivation of totok shells, covering an area of 326,035039 ha. While, stations 2, 4, 5, 6 and 7 (other locations) are " Not Suitable" (Tidak Sesuai) for the cultivation of totok shells, covering an area of 557,057573 ha.

Spatial distribution and concentration of Total Suspended Solid (TSS) is one of the coastal parameters which are required to be examined in order to understand the quality of the water. Rapid development of remote sensing technology has resulted in the emergence of various methods to estimate TSS concentration. SPOT-6 data has spatial, spectral, and temporal characteristics that can be used to estimate TSS concentration. The purposes of this research are (1) to determine the best method for estimating TSS concentration, (2) to map TSS distribution, and (3) to determine the correlation between TSS concentration and chlorophyll-a concentration using SPOT-6 data in Segara Anakan. The estimation of TSS concentration in this research was performed using empirical model built from SPOT-6 and TSS field data. Bands used in this research are single band data (blue, green, red, and near infrared) and transformed bands such as band ratio (12 combinations), Normalized Difference Suspended Solid Index (NDSSI), and Suspended Solid Concentration Index (SSC). The result shows that blue, green, red, and near infrared bands and SSC index significantly correlated to TSS. Afterwards, regression analysis was performed to determine the function that can be used to predict TSS concentration using SPOT-6 data. Regression function used are linear and non-linear (exponential, logarithmic, 2nd order polynomial, and power). The best model was chosen based on the accuracy assessment using Standard Error of Estimate (SE). The selected model was used to calculate total TSS concentration and was correlated with chlorophyll-a field data. The result of accuracy test shows that the model from blue band has an accuracy of 70.68 %, green band 70.68 %, red band 75.73 %, near infrared band 65.58 %, and SSC 73.67 %. The accuracy test shows that red band produced the best prediction model for mapping TSS concentration distribution. The total TSS concentration, which was calculated using red band empirical model, is estimated to be 6.13 t. According to the correlation test, TSS concentration in Segara Anakan has no significant correlation with chlorophyll-a concentration, with a coefficient correlation value of -0.265.

Ikan uceng (Nemacheilus fasciatus) merupakan salah satu spesies ikan air tawar di Indonesia dengan nilai ekonomi cukup tinggi yang ketersediaannya masih mengandalkan penangkapan di alam, sehingga diperlukan upaya domestikasi untuk menjaga kelestariannya. Tujuan dari kegiatan ini adalah untuk mengamati biologi reproduksi dan pola pertumbuhan ikan uceng di lingkungan buatan (akuarium). Ikan uceng hasil tangkapan alam dari Sungai Progo, Temanggung, Jawa Tengah (panjang total 5,55 ± 0,53 cm; bobot 2,49 ± 0,24 g) diadaptasikan selama 12 bulan di akuarium (40 cm × 30 cm × 30 cm) dengan sistem air mengalir yang dilengkapi dengan aerator. Ikan uceng diberi Tubifex, hingga sampai akhirnya dapat beradaptasi dengan pakan komersial. Pakan komersial yang diberikan yaitu sebesar 3% per hari dari biomassa tubuh dengan frekuensi dua kali sehari. Data biologi reproduksi diperoleh melalui koleksi data panjang total, bobot badan, bobot gonad, fekunditas, diameter telur, dan indeks kematangan gonad. Data pola pertumbuhan diperoleh dengan koleksi data panjang, bobot, dan sintasannya. Hasil penelitian menunjukkan bahwa induk betina yang gonadnya berkembang mempunyai warna bintik hitam yang jelas, sebaliknya induk jantan warna bintik hitam memudar. Indeks kematangan gonad (IKG) yang diamati pada ikan uceng setelah 12 bulan pemeliharaan yaitu berkisar antara 0,007-0,027 pada jantan dan 0,13-0,25 pada betina. Kisaran diameter telur yang diamati yaitu berkisar antara 0,61-0,68 mm, dengan fekunditas 680-4.198 butir. Sedangkan pola pertumbuhannya menunjukkan bahwa ikan uceng betina dan jantan memiliki pola pertumbuhan allometrik negatif (b= 2,739 pada betina; b= 2,895 pada jantan). Nilai faktor kondisi Fulton (K) pada ikan uceng yang diamati yaitu 0,44-1,07 (rata-rata ± SD: 0,70 ± 0,11) pada betina dan 0,37-0,72 (rata-rata ± SD: 0,60 ± 0,06) pada jantan. Dari pengamatan ini ditemukan bahwa proses perkembangan kematangan gonad ikan uceng di akuarium lebih lambat dibandingkan ikan uceng di habitat aslinya.Barred loach (Nemacheilus fasciatus) is one of native fish species in Indonesia with high economic value, where their availability still depends on wild capture. Thus, domestication is needed to maintain its sustainability. The purpose of this study was to observe the reproductive biology and growth pattern of barred loach reared in aquarium (artificial environment). Fish were collected from Progo River, Temanggung, Central Java (total length of: 5.55 ± 0.53 cm; body weight: of 2.49 ± 0.24 g). The fish were reared for 12 months in aquarium (40 cm × 30 cm × 30 cm) with flowthrough system and equipped with aeration. The fish were fed with Tubifex until they accepted commercial feed. Then, the fish were fed twice a day at a ratio of 3% from the total fish biomass. The reproductive biology data were collected by measuring their total length, body weight, gonad weight, fecundity, egg diameter, and gonadosomatic index. Growth pattern were measured from length, weight, and survival. The results showed that matured female had shown black spot and male had inconsistent formation of black spots on their body. The gonadosomatic indexes ranged between 0.007-0.027 for male and ranged between 0,13-0,25 for female. The egg diameters ranged between 0.61-0.68 mm, with the fecundity of 680-4198 eggs. The result of observation on growth pattern showed that female and male had negative allometric growth (b= 2.739 for female, b= 2.895 for male). The value of Fulton condition factor (K) in the observed fish was 0.44-1.07 (mean ± SD: 0.70 ± 0.11) on female and 0.37-0.72 (mean ± SD: 0.60 ± 0.06) on male. From this study, it was found that gonad maturity development of barred loach reared in aquarium was slower than those in their natural habitat.

<p><strong>Abstract</strong></p><p>Segara Anakan, Cilacap Regency is an important marine fisheries producer in Central Java <br />Province, especially for shrimps. The objective of this study were to analyze the production and <br />fishing ground of shrimps, to analyze dynamic patterns of shrimps cat ch affected by sedimentation <br />and  industrial waste in Segara  Anakan, and to develop intervention option to the degradation  of <br />shrimp  catch  as  well.   Some  methods  were  used  in  this  study  such  as  descriptive  method, <br />geographic information system, and dynamic model approach included the test of model structural <br />stability and performance. In  2002–2013, the highest production of shrimps in the Segara Anakan <br />was in 2006 (2263.0 ton) and the lowest was in 2010 (884.7 ton). Fishing ground of shrimp in the <br />Segara  Anakan  already  had high total suspended solid, and also  low contaminated oil and  lead <br />(Pb). Results of dynamic model analysis showed that shrimp catch degraded exponentially along <br />with the increasing of sediment accumulation and industrial waste. Shrimps production in 2013 was <br />1147.8  tons,  and  might  decrease   43.04  %  to  be  653.8  tons  over  75  years  later  without <br />intervention. If the model was intervenced by fishing open -close system and limited acces fishing <br />ground,  hence  shrimps  catch  showing  stable  around  902.2–929.1  ton  every  year.  While  if  the <br />intervention was conducted by the stopping of industrial waste to Segara Anakan, hence shrimps <br />catch only decrease 13.00 % to be 998.6 tons over 75 years later.<br /><br />Keywords: dynamic model, fishing ground, industrial waste, shrimp catch</p><p><strong><br /></strong></p><p><strong>Abstrak</strong></p><p><strong></strong>ABSTRAK<br />Segara Anakan, Kabupaten Cilacap merupakan basis produksi perikanan laut yang penting <br />di  Provinsi  Jawa  Tengah  terutama  jenis  udang.   Penelitian  ini  bertujuan  menganalisis  kondisi <br />produksi dan daerah penangkapan udang, menganalisis pola dinamis penurunan hasil tangkapan <br />udang  akibat  pengaruh  pengendapan  dan  pembuangan  limbah  industri  di  kawasan  Segara <br />Anakan,  serta  mengembangkan  alternatif  intervensi  secara  modelling  terhadap  penurunan <br />tersebut.  Metode  yang  digunakan  terdiri  dari  metode  deskriptif,  sistem  informasi  geografi, <br />pendekatan  model  dinamis,  serta  uji  kestabilan  struktur  dan  kinerja  model.  Pada  periode  tahun <br />2002  –  2013, produksi tertinggi udang terjadi pada tahun 2006 (2263,0 ton) dan terendah terjadi <br />pada tahun 2010 (884,7 ton). Daerah penangkapan udang di kawasan Segara Anakan mempunyai <br />total padatan tersuspensi dan kekeruhan yang tinggi, serta tercemar ring an oleh minyak dan logam timbal. Analisis model dinamis menunjukkan bahwa hasil tangkapan udang cenderung menurun <br />secara eksponensial seiring meningkatnya akumulasi endapan  dan cemaran limbah industri dari <br />waktu  ke  waktu.  Hasil  tangkapan  udang  yang  saat  ini  (tahun  2013)  mencapai  1147,8  ton,  bisa <br />menurun 43,04 % menjadi 653,8 ton setelah 75 tahun kemudian. Bila model tersebut diintervensi <br />dalam  bentuk  penerapan  sistem  open-close  dan  pembatasan  daerah  penangkapan  yang  bisa <br />diakses,  maka  hasil  tangkapan  udang  cenderung  stabil  pada  kisaran  angka  902,2  –  929,1  ton <br />setiap  tahunnya.   Akan  tetapi  bila  intervensi  dilakukan  dalam  bentuk  penghentian  pembuangan <br />limbah industri ke kawasan Segara  Anakan  dan sekitarnya, maka hasil  tangkapan udang hanya <br />turun 13,00 % (menjadi 998,6 ton) setelah 75 tahun kemudian.<br /><br />Kata kunci: model dinamis, daerah penangkapan, limbah industri, hasil tangkapan udang</p>

The large number of activities along the West Banjir Kanal river has triggered a change in the condition of its sea waters. The condition most affected is turbidity which caused high concentration of Total Suspended Solid (TSS) in estuary waters and interfere with the entry of sunlight into the waters. The purpose of the study is to determine the effect of the of concentration TSS on the concentration chlorophyll a and dissolved inorganic phosphate (DIP) in the waters of West Banjir Kanal estuary. Water sampling was conducted on October 3, 2019. Water quality parameters such as brightness, pH, temperature, DO and salinity were measured in situ. Meanwhile, chlorophyll a, TSS and DIP measurements were analyzed in the laboratory. The results showed that the highest concentration of TSS, chlorophyll a and DIP were in the estuary area and decreased with further distance from the river mouth with concentration were 70.17-151.50 mg/L, 0.03–2.67 µg/L and 0.71–0.98 µM respectively. Based on the results of the Principal Component Analysis (PCA) showed that TSS affected chlorophyll a by 8.7% (r=0.392; p<0.05) and DIP by 54.46% (r=0.931; p<0.01). The low regression between TSS and chlorophyll a was due to the presence of large amounts of inorganic particles in the West Banjir Kanal river, which makes the river waters become turbid. So, the turbidity of the waters caused the release of phosphate in the sediment to water column which was used by phytoplankton for photosynthesis, so the TSS not only contain sediment particles, but also phytoplankton. Banyaknya aktivitas di sepanjang sungai Banjir Kanal Barat Semarang, memicu kondisi perairan lautnya menjadi berubah.  Kondisi yang paling terpengaruh adalah kekeruhan yang menyebabkan tingginya konsentrasi Material Padatan Tersuspensi (MPT) di perairan muara dan mengganggu masuknya cahaya matahari ke perairan. Penelitian ini bertujuan untuk mengetahui pengaruh MPT terhadap konsentrasi klorofil-a dan fosfat inorganik terlarut (DIP=Dissolved Inorganic Phosphate) di perairan Muara Banjir Kanal Barat Semarang. Pengambilan sampel air dilakukan pada tanggal 3 Oktober 2019. Parameter kualitas perairan seperti kecerahan, pH, suhu, DO dan salinitas diukur secara in situ. Sedangkan pengukuran klorofil-a, MPT dan DIP dianalisis di laboratorium. Hasil penelitian menunjukkan bahwa konsentrasi MPT, klorofil-a dan DIP tertinggi di daerah muara sungai dan menurun dengan makin jauhnya muara sungai dengan konsentrasi secara berturut-turut sebesar 70,17-151,50 mg/L, 0,03-2,67 µg/L dan 0,71-0,98 µM. Berdasarkan hasil Analisis Komponen Utama (AKU) menunjukkan bahwa MPT mempengaruhi klorofil-a sebesar 8,7% (r = 0,392; P < 0,05) dan fosfat inorganik terlarut sebesar 54,46% (r = 0,931; P < 0,01). Rendahnya hubungan antara MPT dengan klorofil-a ini disebabkan oleh adanya masukan partikel anorganik dalam jumlah besar di badan Sungai Banjir Kanal Barat yang membuat perairan sungai menjadi keruh. Jadi kekeruhan perairan menyebabkan terlepasnya fosfat di sedimen yang dimanfaatkan oleh fitoplankton untuk proses fotosintesa, sehingga yang terkandung dalam MPT selain partikel sedimen juga fitoplankton.

The oceanographic characteristics of Klabat Bay in Bangka Island of Indonesia were investigated by using a series of temperature, salinity, turbidity, TSS (total suspended solid), transparency, DIN (Dissolved Inorganic Nitrogen), DIP (Dissolved Inorganic Phosphorus), DO (Dissolved Oxygen) and chlorophyll-a data in the wet season (Northwest Monsoon) and dry season (Southeast Monsoon) of 2003, respectively. The observation results show that the hydro-oceanographic characteristics of Klabat Bay in the inner part and the outer part of the bay were dominantly influenced by the terrestrial and oceanic environment, respectively. High precipitation during the wet season decreased salinity, DO and transparency and increased total suspended solid (TSS), turbidity, DIN and chlorophyll-a within the bay. The reverse occurred during the dry season, except DIP.
