Abstract

The aim of the study was to investigate the effect of different types of carbohydrates on growth, survival, feed efficiency and fish production (Pangasius pangasius), in the biofloc system with zero-water exchange. Added carbohydrates were tapioca, molasses, bran and cornstarch which were set at level of 25% of the theoretical adding quantity. A total of 6000 fish larvae used in this experiments. Complete Randomized Designed was used with four treatments and three replications. Twelve tanks used in which each tank was a cylinder tank (1814.92 L) and each tank contained 500 fish. The results showed that the concentrations of ammonia and nitrite differ significantly in the experimental tank added maize when compared to other carbohydrate sources. The nitrate levels showed that highly concentration was observed in the maize treatments compare to tapioca and molasses treatments, however it was not significantly different than that of rice bran treatments. The floc volume stabilized after about 3 weeks in the BFT tanks. Different carbon sources had resulted in different proximate composition tendencies. The highest yield obtained in molasses treatments which were highest compare to all carbohydrate treatments, whilst tapioca, rice bran, and maize treatments were not significantly different

Abstract

Gouramy (Osphronemus gouramy) has very high economic value and is easy to cultivate. Currently there are about six strains that have been successfully cultivated based on their reproductive ability to produce eggs, namely goose (soang, goose gouramy), jepun (japan, japonica), blue sapphire, paris, bastar (broiler) and porcelain. One of the reasons for these differences in ability is internal factors which can be seen through the identification and expression of the cGnRH gene that each of these gouramy strains have. The cGnRH gene functions in signaling the pituitary gland to secrete the hormone GtH. This study aims to identify sequences and gene expression values ​​resulting from three strains of gouramyat different age levels. The research method used was the exploration of three gouramy strains (soang, jepun, blue sapphire) at different age levels (4 months, 8 months, 12 months), and three gouramy strains were taken for each age level. This research was conducted through several stages, namely organ preparation, isolation, sequence identification and measurement of cGnRH gene expression. Sequence data was analyzed using phylogenetic trees and gene expression was analyzed using One Way ANOVA test. The sequence results showed that the soang strain had a sequence that was more similar to the jepun strain than the blue sapphire strain, and the resulting gene expression showed that the three gouramy strains with three different age levels did not give different results.

Abstract

Penentuan variabel penting merupakan hal yang sangat diperlukan untuk mengelola secara lestari dari ekosistem mangrove dan laguna Segara Anakan. Penentuan variabel penting tersebut dilakukan melalui aktivitas FGD dengan beberapa stakeholder yang berperan dalam pengelolaan ekosistem mangrove dan laguna Segara Anakan. Aktivitas ini bertujuan untuk meningkatkan pemahaman stakeholder dalam pengelolaan ekosistem Segara Anakan dilakukan dengan menggunakan simulasi MICMAC. Aktivitas sosialisasi dan simulasi dilakukan dengan melibatkan stakeholder yang dikelompokan menjadi beberapa cluster pelaku yaitu pemerintah (baik pemda maupun dinas), perangkat dan aparat desa, masyarakat, industri (pertamina, industry semen dan pembangkit listrik), andong perahu dan beberapa pakar.   Hasil simulasi dan sosilasisasi meningkatkan pemahaman masyarakat melalui penentuan variabel utama yaitu tsunami, ROB, limbah, abrasi, sedimentasi, dan pencemaran, tambak dan perubahan fishing ground. Variabel tersebut  menjadi variabel utama yang sangat mempengaruhi keberlanjutan ekosistem mangrove dan laguna Segara anakan

Abstract

Bencana pesisir merupakan bencana yang memberikan ancaman yang sangat tinggi bagi masayarakat di pesisir selatan Cilacap. Cilacap merupakan wilayah yang memiliki tingkat ancaman bencana yang sangat tinggi.  Beberapa ancaman bencana pesisir yang terjadi di Cialcap adalah tsunami, banjir pasang surut (ROB), pencemaran dan abrasi pantai.  Untuk mengurangi resiko bencana tersebut, maka masyarakat perlu beberapa aktivitas yaitu meningkatkan pemahaman tentang bencana pesisir, serta meningkatan kapasitas dan menguramgi kerentanan melalui aktivitas pertolongan pada kecelakaan (P3K). Aktivitas pertolongan pertama pada kecelakaan merupakan aktivitas memberikan kemampuan masyarakat melakukan pertolongan sendiri dan komunitasnya ketika terjadi bencana tanpa menunggu bantuan relawan datang. Aktivitas simulasi first aids dilakukan melalui tahapan memberikan pemahaman tentang bencana pesisir, manfaat first aids dan simulasi first aids. Hasil simulasi menunjukan bahwa maysaraakat awalnya tidak paham tentang bencana pesisir (56%), namun mereka paham bahwa ROB (38%), tsunami (26 %) dan pencemaran air (21%) merupakan bencana pesisir yang tertinggi ancamannya. Masayarakat sangat berharap untuk aktivitas rehabilitasi mangrove, pembentukan forum kebencanaan dan simulasi P3K secara periodik

Abstract

The mangrove ecosystems are one type of coastal ecosystem found along coastlines and river estuaries that are influenced by tides and inundation. Segara Anakan Lagoon, Cilacap as one type of coastal ecosystem has a protection function, coastal area buffer, and cultivation area function that must be supported from the aspects of policy and institutions, communication, and coordination. This study aims to identify the role of stakeholders and the relationship between stakeholders in mangrove ecosystem management in Segara Anakan Lagoon, Cilacap. The research method used was a survey and interview method analyzed with MACTOR software. The results showed that there were 18 stakeholders who involved in mangrove ecosystem management in Segara Anakan Lagoon, Cilacap. The stakeholders are classified into main stakeholders, key stakeholders, and supporting stakeholders using the objective of mangrove management as key activities such as silvofishery, mangrove conservation, fishing activity, industry activity, etc. The level of convergence between stakeholders was 96.1% and the level of divergence was 3.9%. These results indicate a relatively low potential for conflict between stakeholders. The research can be used as a model relation between stakeholders to support the management activity of Segara Anakan Lagoon.

Abstract

Mangrove ecosystem in Segara Anakan Lagoon (SAL) Cilacap as a typical and specific semiclosed estuary. SAL  is dominated by many species like as Rhizophora spp., Sonneratia spp., Bruguiera spp., Avicennia spp., and other species. The normalized different vegetation index (NDVI) and dominant vegetation index (DVI) are a suitable method to support the mapping analysis of mangrove structure and mangrove density.  This research aimed to develop mapping of mangrove species distribution, density and dominated species using NDVI and DVI.  The method of this research used NDVI analysis using satellite imagery 2017-2020 and domination vegetation with line and quadrat transect method. The results showed that  West Segara Anakan had mangrove dense (25 %), moderate density (25 %), rare density (50%) and East Segara Anakan had mangrove dense (43,86 %), moderate density (47.99 %), rare density (8,24 %).  Based on domination species showed that East Segara Anakan was dominated by Rhizophora stylosa (233-1633 trees ha-1), Rhizophora apiculata (100-1067 trees ha-1), Nypa frutican (50-2775 trees ha-1), whereas West Segara Anakan was dominated by Nypa frutican (565-2333 trees ha-1), Avicennia marina (198-933 trees ha-1), Sonneratia caseolaris  (132-700 trees ha-1) and Avicennia alba (107-1000 trees ha-1). Keywords : Mangrove density, mapping analysis, Segara Anakan Lagoon, NDVI and NDWI
