OSMOTIC RESPONSES OF SEGARA ANAKAN FINE SHRIMP (Metapenaeus elegans) ADULTS IN VARIOUS SALINITY AND MOLTING STAGES
No full textA research on eco-physiological characteristics of fine shrimp (Metapenaeus elegans) with special emphasis on the osmotic responses and isosmotic medium requirement for adult spawners in various molting stages was conducted. Adult stocks of M. elegans origin from the Segara Anakan lagunas of the South West of Central Java region were collected and used as experimental shrimps. The shrimps were hold in three 500 l-acclimation tanks and treated according to Anggoro and Nakamura’s method. The seawater salinity level in the tank 1, 2, and 3 was 25, 28, and 22 ppt, respectively. Osmotic response of the shrimps was examined during 3 molting stages, i.e. pre-molt/ post-molt, molt, and inter-molt phases by using an automatic microosmometer Roebling. The results showed that osmotic responses were closely related to the salinity of water medium and molting stages. It was also found that the minimum osmotic works of fine shrimp occurred in isosmotic medium, i.e. 16 to 20 ppt for post-molt, 28 to 30 ppt for molt, and 22 to 25 ppt for inter-molt stages. It was concluded that the range of isosmotic media for the adult of fine shrimp was 22 to 28 ppt or equals to 642.06 to 817.31 mOsm/l H2O

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-8 Tahun 2020, Palembang 20 Oktober 2020. pp. xx. Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Ciujung River is one of the largest rivers in Banten Province, resident in Ciujung River basin still use water from Ciujung to fulfill their daily needs, the other designation of Ciujung river is as receiver industrial, domestic and agricultural waste, until 2020 result of monitoring Ciujung river was polluted. This study aims to develop a management strategy for Ciujung River. Pollution index method is used to determined water quality status of Ciujung River, AHP method is used in determined priority of criteria and sub-criteria in management of Ciujung River. This study began with calculated pollution index in 2017-2019, next step is AHP hierarchy arrangement and the pairwise comparison matrix, then distributed questionnaires to 10 respondents and data was analised using Expert Choice 11 software. Results of analysis use AHP show that the most influential criteria in managing Ciujung River is goverment policy, the most influential management objective was to improve the quality of Ciujung River water, and the most influential goverment policy was law enforcement. Ciujung river strategy management that must be carried out by goverment is law enforcement to improve water quality

No full textAnalisis Konflik Eksternal dan Internal Tokoh Utama dalam Novel Macan Kertas Karya Budi Anggoro
No full textThis study aims to gain an understanding of the external and internal conflicts in the novel's main character and presents the results of research material for learning materials in schools. The method used in this research is a qualitative descriptive method in the form of a structural approach. The data in this study is a literary text which includes external and internal conflict in the novel Macan Kertas. Data collection techniques with techniques of documentary studies by way of reviewing literature becomes a source of research data. Based on data analysis, novel Macan Kertas discusses external conflict is a conflict with the main character Ma'am barrel, the market administrator, officer and head of the Department of Market Management, hired thugs and Lutfi husband. Not only that there is also an internal conflict the main character is feeling sad, angry, disappointed, anxious, upset, regret, fear, happy, surprised, worried and wonder. The result is expected to be a reference for the development of subsequent research that want to study novel by Budi Anggoro with another theory. Would be much better reader works Budi Anggoro understand the context in these work, so bring meaning conveyed author
ANALYSIS OF WATER SALINITY LEVEL OF FREQUENCY MOLTING IN VANNAMEI SHRIMP (LITOPENAEUS VANNAMEI) ABLATED
No full textMedia salinity is a masking factor that plays an important role in controlling the process of shrimp molting and osmoregulation. Both of them are ecophysiological factors for shrimp life, so it is necessary to know the optimum level or range of media salinity for each phase of the molting phase changes in the stage and osmoregulation phase. This study was conducted to examine the molting frequency of adult L. vannamei which was ablated and cultivated at various levels of salinity. This research was carried out for 60 days. This study uses experimental laboratory methods with a systematic randomized design (RAS) with 4 treatments and 3 replications in each treatment. The treatments tested were salinity with S1 treatments (10 ppt, 289.20 mOsm / l postmolt H2O isosmotic), S2 (15 ppt, 432.80 mOsm / l H2O initial intermolt isosmotic), S3 (25 ± 1 ppt, 725, 15 mOsm / l H2O isosmotic final intermolt) and S4 (29 ± 1 ppt, 820.10 mOsm / l H2O isosmotic molt). Data were analyzed with ANOVA. Meanwhile, the difference in effect between treatments was obtained through Duncan's multiple area test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency was in the S4 treatment (29 ± 1 ppt) (close to isoosmotic molt) 10 times. In the maintenance of L. vannamei which is affixed, it should pay attention to the needs of isoosmotic media, namely media with a salinity of 25 ± 1-29 ± 1 ppt (final intermolt isoosmotic range / premolt to molt). the difference in effect between treatments was obtained through Duncan's multiple region test. ANOVA results showed that various levels of isoosmotic media salinity at various molting phases had an influence (p <0.05) on molting frequency. The best value of molting frequency is in the treatment of S4 (29 ± 1 ppt) (close to isoosmotic molt) 10 times.

Ethnotaxonomical Study of Mole Crab (Crustacea:Hippoidea) on Coastal Community of Cilacap
No full textLocal wisdom is a cultural heritage that needs to be preserved. The Cilacap’s coastal communities have traditional taxonomy knowledge that hasn’t been informed, especially about mole crab. This study aimed to explore the ethnotaxonomy knowledge of sand crabs (Crustacea: Hippoidea) in Widarapayung coastal communities. The purposive snowball sampling was used for the method, followed by observation and semi-structured interviews with 30 respondents. Data were analyzed descriptively based on observations and interviews. The results showed that the coastal communities in Widarapayung tourist areas could be divided into five groups, namely catchers, collectors, processors, traders, and consumers. The catcher was able to recognize and describe three types of sand crabs based on the shape of the body and their catchment areas. Captured crabs had the local name of ‘yutuk jambe’ (Emerita emeritus Linnaeus 1767), the appellation was based on carapace shape that resembled the shape of areca fruit; ‘Yutuk bathok’ (Hippa adactyla Fabricius 1787), had the carapace shape resembling a coconut shell, and ‘yutuk Kethek’ (Albunea symmysta Linnaeus 1758), had ornaments on the carapace surface similar with a monkey face, there were dense setae on the edge of the carapace, spiny long antennas and aggressively pinch when captured. The knowledge and skills of sand crabs classification and local name entitlement acquired by the people were in accordance with the Berlin’s model.
