Abstract

Variabilitas cuaca dan iklim di Indonesia disebabkan oleh berbagai macam faktor skala ruang dan waktu, baik yang bersifat lokal, regional, maupun global dengan variasi waktu harian, bulanan, musiman, hingga tahunan. Pada skala waktu harian hingga intramusiman, MJO menjadi faktor utama variabilitas di wilayah tropis, sedangkan pada skala global yang bersifat tahunan, El Nino dan La Nina memberikan kontribusi terbesar. Penelitian ini bertujuan untuk mengkaji karakteristik MJO yang aktif bersamaan dengan La Nina kuat pada tahun 2011/2012. Metode pengolahan data menggunakan bahasa pemrograman untuk mengolah data RMM1 dan 2, suhu permukaan laut, outgoing longwave radiation, angin zonal 850 hPa dan 200 hPa, fluks panas laten, kelembapan udara relatif (Rh), dan curah hujan. Hasil menunjukkan saat MJO aktif bersamaan dengan La Nina kuat, SPL di wilayah tropis berada dalam kondisi hangat berkisar antara 29–30.50C yang terpusat di perairan Indonesia bagian timur dan Samudera Pasifik. Beberapa kondisi angin zonal lapisan 850 hPa menunjukkan intrusi angin timuran dengan kecepatan yang signifikan sebagai dampak dari pengaruh La Nina terhadap propagasi MJO. Gangguan angin timuran tidak terlalu mempengaruhi pertukaran panas laut-atmosfer dalam bentuk fluks panas laten, sehingga tetap bernilai positif. Kondisi basah La Nina dan MJO menyebabkan peningkatan Rh pada lapisan 1000–500 hPa sebesar 80-90% dan pada lapisan 200 hPa sebesar 70-80%. Hal ini mendukung propagasi dan memperpanjang durasi MJO yang aktif di perairan tropis. Pengaruh La Nina yang cukup kuat saat MJO aktif mendukung pertumbuhan awan konvektif sehingga terjadi peningkatan curah hujan sebesar 10–200 mm perhari.   Weather and climate variability in Indonesia is caused by various factors of space and time scale, both local, regional, and global with daily, monthly, seasonal, and yearly variations in time. On a daily to the intra-seasonal time scale, the MJO is the main factor of variability in the tropics, while on an annual global scale, El Nino and La Nina make the largest contribution. This study aims to examine the characteristics of the MJO that was active at the same time as strong La Nina in 2011/2012. The data processing method uses a programming language to process data RMM1 and 2, sea surface temperature, outgoing longwave radiation, 850 hPa and 200 hPa zonal winds, latent heat flux, relative humidity (Rh), and rainfall. The results show that when the MJO is active along with strong La Nina, SST in the tropics is in warm conditions ranging from 29 - 30.50C which is concentrated in the waters of eastern Indonesia and the Pacific Ocean. Several zonal wind conditions of the 850 hPa layer showed easterly wind intrusion with significant speed as the impact of La Nina influence on MJO propagation. The east wind disturbance does not significantly affect the ocean-atmosphere heat exchange in the form of latent heat flux, so it remains positive. Wet conditions of La Nina and MJO caused an increase of Rh in the 1000–500 hPa layer by 80-90% and in the 200 hPa layer by 70-80%. This supports propagation and extends the duration of active MJOs in tropical waters.

Abstract

Kajian potensi dan pemanfaatan udang (Penaeus spp) di perairan pantai Kabupaten Batang dilakukan berdasarkan analisis terhadap data hasil tangkapan dan trip penangkapan udang selama kurun waktu 2002-2011. Analisis catch per unit effort (CPUE) digunakan untuk menduga potensi lestari (MSY) udang dan upaya penangkapan yang optimum. Analisis juga dilakukan untuk mengetahui keadaan musim penangkapan berdasarkan data kuartalan. Nilai MSY dan upaya penangkapan udang di  Kabupaten Batang masing –masing adalah 29.032 kg dan 18.262 trip tahun-1. Musim penangkapan udang tertinggi terjadi pada kuartal I yaitu pada bulan Januari-Maret dan semakin menurun hingga kuartal III (Juli-September). Diketahui bahwa status perikanan udang pada tahun 2005-2006 dan tahun 2010-2011 telah menunjukan overfishing, sehingga diperlukan upaya pengaturan. Pengaturan lebih ditujukan pada pembatasan hasil tangkapan dan upaya penangkapannya dengan jaring arad, yaitu 80% dari potensi lestarinya. Kata kunci : Analisis CPUE, udang (Penaeus spp), MSY, perairan pantai Kabupaten Batang.The study of potential and shrimp resource utilization (Penaeus spp) in Batang Regency coastal waters made based on analysis of the catching data and shrimp fishing trip during the period 2002-2011. Analysis of the catch per unit effort (CPUE) is used to predict the long-lasting potential (MSY) shrimp and optimum fishing effort. The analysis were also conducted to determine the state of fishing season based on quarterly data. MSY value and shrimp fishing effort in Batang respectively 29,032 kg and 18,262 trip. The highest shrimp fishing season was in the first quarter that is in January-March and decreased in the third quarter (July-September). It is known that the status of the shrimp fishery in 2005-2006 and in 2010-2011 have shown overfishing, so the effort settings required. The setting is more aimed at limiting the catch and the catch effort with arad net, ie 80% of the long-lasting potential.

Abstract

Nelayan yang tinggal di sekitar perairan pantai Kabupaten Batang adalah pihak yang secara langsung memiliki hubungan dengan perairan dan menggunakan jaring arad sebagai alat yang digunakan untuk memanfaatkan produknya. Ketergantungan nelayan di sekitar perairan pantai Kabupaten Batang dalam memanfaatkan sumber daya alam masih tinggi sehingga memerlukan usaha alternatif untuk meningkatkan perekonomian mereka melalui program pemberdayaan nelayan. Daya nelayan adalah elemen yang memungkinkan nelayan bertahan hidup dan dapat mengembangkan diri dalam mencapai kemajuan dan kekayaan. Penelitian ini bertujuan untuk mengetahui tingkat daya sosial dan ekonomi nelayan jaring arad yang berada di perairan pantai Kabupaten Batang dan peran pemangku kepentingan terkait dalam pemberdayaan nelayan. Untuk mendapatkan data primer, survei dilakukan untuk 145 responden (±30% dari nelayan yang ada di perairan pantai Kabupaten Batang) pada bulan Maret tahun 2014. Kemudian dilakukan analisis deskriptif dan crosstab. Tingkat daya nelayan jaring arad di perairan pantai Kabupaten Batang masih dikategorikan ke dalam berdaya, baik dari aspek ekonomi dan non. Hal ini dapat dilihat dari rendahnya akses teknologi, keputusan bisnis, dan keterampilan lobi. Para pemangku kepentingan yang membantu bisnis nelayan sebagian besar berasal dari pemerintah dan masyarakat dengan skor 7 (cukup). Oleh karena itu, strategi pemberdayaan diperlukan untuk meningkatkan daya nelayan sehingga peningkatan kesejahteraan dapat terwujud.Kata kunci : Nelayan jaring arad, tingkat keberdayaan, perairan pantai kabupaten BatangFishermen who live around the coastal waters of the Batang which is directly linked to water and use nets arad as a tool that is used to exploit its products.

Abstract

Teluk Awur Beach Jepara is one of the waters in Central Java that has a seagrass ecosystem. Seagrass role is the ability to support the life of another biota closely related to the fertility of the waters indicated by the content of chlorophyll-a, nitrate, and phosphate. The purpose of this study is to know the relationship between chlorophyll-a, nitrate, and phosphate to seagrass land cover as well as the variables which have major contributions. The method of study used is descriptive with four station sampling and  seagrass with a line transect of 50 m, and a 1x1 m² transect Quadrant divided into 16 sub plots measuring 25 x 25 cm² a spatial approach and multiple regression statistics. The results showed that there was a positive correlation between seagrass land cover to the concentration of chlorophyll-a and nitrate but less correlated phosphate. The highest chlorophyll-a concentrations of 0.381 mg/m3, seagrass land cover 40-60%, seagrass density 314 individual/m2, nitrate 1.141 mg/l and phosphate 0.54 mg/l. The lowest chlorophyll-a concentration ranges from 0.32-0.35 mg/m3, seagrass cover of 0-10%, seagrass density 3-12 individual/m2, nitrate 0.96 mg/l and phosphate 0, 21mg/L. This research shows that there is a strong link between seagrass land cover Concentrations of chlorophyll-a, nitrates and less influential to phosphates.

Abstract

The purpose of this study was to determine the distribution of CO2 flux in Karimunjawa in the east monsoon.  The variables in this study were temperature; pH; salinity; DO; CO2 atm was measured using a CO2 meter; chlorophyll-a, phosphate, silicate were measured spectrophotometric method. Total Alkalinity / TA was measured using the titration method with the principle of changing pH; DIC (Dissolved Inorganic Carbon) was measured using CO2sys software. The partial pressure of seawater carbon dioxide calculated using formula: pCO2sea = 6.31T2 + 61,9 Chla2 – 365.85T – 94.41 Chl-a +5715.94, the partial pressure of atmospheric carbon dioxide calculated using formula: pCO2atm = xCO2atm (pb - pH2O).  The calculation of the estimated CO2 flux using the formula: Flux CO2 = Kh x kwa x (∆pCO2)  , if the CO2 flux has a positive value water acts as a CO2 source, and if it is negative, the waters act as a CO2 sink..  CO2 flux in Karimunjawa waters during east monsoon (represented by August 2018) showed that in Karimunjawa waters with normal pH 7.2-7.4 were dominated by bicarbonate ion HCO3-with an average value of  DIC 1847.24 µmol/kg dan TA 1912.51 µmol/kg.  The partial pressure of seawater CO2 is higher than the partial pressure of atmospheric CO2  this indicates that the role of Karimunjawa waters as a source of CO2 where there is release of carbon dioxide into the atmosphere with CO2 flux values ranging from 8.549 – 13.272 mmol m-2 day-1.  The variables that affect the flux of CO2 were the pCO2sea and ΔpCO2 with a very strong and positive correlation. These two variables were influenced by sea water temperature, salinity, chlorophyll-a, phosphate and silicate.

Abstract

ABSTRACTIndonesia is a maritime country which most of the territory is ocean, where many people have activities at sea.  Information about variations and characteristics of wave height in some region is very important to support safety and efficiency of the activity. The purpose of the research is to know and analysis the characteristics of the monthly variations of wave height in the water of North Sulawesi. The data used in this study is a surface wind that processed into Windwaves-05 wave model. This model calculates wave height based on energy from surface wind that blows above the sea surface. The research results showed that variations of sea waves in the waters of North Sulawesi generally are closely related to the monsoon wind patterns that occur in Indonesia. When Asian west monsoon in November to April, the average wave height in the waters of North Sulawesi is higher than wave height at Australian east monsoon in May to October.  The highest average wave occurred in January with maximum wave height to 3.5 m and lowest average wave occurred in October with a maximum height to 1.25 m. Generally, the average wave height in the waters which bordering the ocean is higher than the waters close to all major islands.

Abstract

Diversification of feed rich in natural carotenoids is needed in aquaculture because they will increase survival and body weight of animal farming. Different types of important carotenoids such as β-carotene, zeaxanthine can be combined through a process of protoplast fusion making it cheaper and faster. Crustaceans can not synthetize carotenoid de novo and they need it to provide nutrition and possibly disease resistance, pigmentation and esthetic value. Green microalgae produce carotenoids and can be manipulated easily by protoplast fusion. The research was conducted to obtain some fusants from interspesies protoplast fusion of D. salina and C. vulgaris. Interspecies protoplas fusion was carried out by protoplast isolation, protoplast fusion and protoplast regeneration. Microscopic and cell analysis will used to confirm positive regenerate protoplast. Analysis of the obtained fusants is limited to morphological description due to the complexity and variability of fusant. The stabilities of fusants obtained were examined by successive subcultures. The result revealed that the fusant from D. salina and C. vulgaris maintain their stability in growth and increased carotenoid production during four periods of subculturing. This result suggesting the potency of fusant to be used as food supplement.   Key words: Carotenoid, Protoplast fusion, Dunaliella, Chlorella

Abstract

The presence of aeration on the cultivation of polyculture system can eliminate oxygen depletion at night while the intensity of light would effect the seaweed Gracilaria verucosa to perform photosynthesis. The supplies of oxygen is to eliminate the oxygen depletion at night until morning, and propose the efficiency of feeding activity, and also stabilize the water quality. The purpose of this research is to improve the survival, growth and production of vaname shrimp, and Gracilaria verucosa. This research was conducted in Jepara Brackishwater Aquaculture Research and Development Center (BBPBAP), from May until August 2013. A number of 75 shrimps and 1,750 g Gracilaria vericosa were cultivated in the 800 L tank, which observed for 96 days. There are four type of treatments, oxygen supply O1 (3,500 lux light intensity), O2 (Aeration with 700 mL minute-1 speed), O3 (light intensity and aeration), O4 (without light and aeration), three replications. This research was conducted using an experimental Randomized Block Design. The survival rate and growth of shrimp (Litopenaeus vannamei) showed a highly significant (p < 0.01) different between the treatments, while the growth and biomass production of seaweed (Gracilaria verucosa) showed a significantly (p < 0.05) different. The three treatments of oxygen and light supply, aeration and the combination of light and aeration, it can be concluded that survival, growth and production of vaname shrimp and Gracilaria verucosa. The combination of light and aeration treatment is the best, it can be concluded survival rate of shrimp (94.64%) compare to the treatment without oxygen (45.24%). Absolute growth rate of shrimp increased from 9.57 g to 12.97 g. The specific growth rate of shrimp increased from 4.73% to 5.07%. The biomass production of shrimp increased from 181.56 g m-2 to 883.95 g m-2. The combination of light and aeration can improve the absolute growth rate of Gracilaria verucosa from 25.86 g to 52.724 g. The specific growth rate of seaweed increased from 1.77% to 2.64% then biomass production of Gracilaria verucosa also to increase from 2,557.76 g to 5,063.2 g.   Key words: Litopenaeus vannamei, Gracilaria verucosa, oxygen supply

Abstract

ABSTRACTLagoon Area of Segara Anakan (SAL) have influence of natural and anthropogenic factors impacting on the increasing of macronutrient, ecologically SAL is downstream from several rivers watershed Citanduy. SAL is tropically moist and influenced monsoon wind, causing the fluctuated waters. The purpose of this research is to recognise the characteristic spatio-temporal makronutrien lagoon. The measurements of macronutrient, include: TN (Total of Nitrogen), NH3 (Ammonia), NO3- (Nitrate), TP (Total of Phosphate), and PO43- (Orthophospat), using methods of spectrophotometric and micro-kjeldahl. The spatial approach is done on 7 stations (S) with representations: (S) natural factors and (S) the presence of anthropogenic activities. The temporal approach (time series) for a year refers to the monsoon wind pattern (west, transition I, east and transition II) season. The results of laboratory tests are discussed descriptively and adapted to the Indonesian standart of waters quality. To facilitate spatio-temporal interpretation, the data is presented formingly a thematic map. Temporal results show in the west season, the highest macronutrient content is dominated by TN (0.587 ± 0.223) mg / L, NH3 (0.875 ± 1.290) mg / L and PO43- (0.390 ± 0.909) mg / L, while NO3- (0.185 ± 0.015 ) mg / L and TP (0.155 ± 0.026) mg / L highest during transitional season II. In the spatial approach, (S) with anthropogenic characteristics contribute to the whole height of the macronutrients. The effects of rainfall, anthropogenic pressure, aquatic hydrodynamics and the contribution of metabolic waste discharged from organisms, are thought to cause in the increasing of SAL macronutrients. Management and lagoon management strategies are required by the local government, stakeholders and communities to prevent the phenomenon of eutrophication of the lagoon. Key words: Macronutrient, Nitrogen, Phospate,  lagoon of  Segara Anakan
