Penelitian ini bertujuan untuk menganalisis sistem sosial - ekologi yang terdapat di Desa Blanakan, Desa Tanjungtiga, Desa Rawameneng, dan Desa Mayangan serta mengetahui jaringan konektivitas sistem sosial - ekologi dari desa pesisir yang terintegrasi. Data yang dikumpulkan berupa data primer dan sekunder terkait sistem sosial dan sistem ekologi, analisis data dilakukan secara deskriptif kuantitatif dan spasial deskriptif. Hasil penelitian menunjukkan bahwa sistem sosial ? ekologi Desa Blanakan, Desa Tanjungtiga, Desa Rawameneng, dan Desa Mayangan tersusun atas jaringan sumberdaya berupa sumberdaya ikan, sumberdaya ekosistem, sumberdaya lahan, dan sumberdaya air yang digunakan oleh nelayan, petani, dan masyarakat umum. Keberlanjutan pemanfaatan sumberdaya didukung oleh ketersediaan infrastruktur yang disediakan oleh pemerintah dan swasta. Jaringan konektivitas sistem sosial - ekologi dari integrasi desa pesisir menunjukkan bahwa sistem sosial antar desa pesisir terkonektivitas melalui interaksi pendidikan, kelembagaan nelayan, pelayaanan kesehatan, dan interaksi lainnya, sedangkan interaksi sistem ekologi terkonektivitas melalui jaringan fishing ground dan pemanfaatan ekosistem mangrove secara bersama terutama antara Desa Blanakan dan Desa Mayangan.  ABSTRACTThe interactions of the socio-ecological systems in the coastal villages often create problems, ranging from the declining ecological quality to social conflicts. This study aimed not only to analyze the socio-ecological systems in the villages of Blanakan, Tanjungtiga, Rawameneng, and Mayangan, but also to find out the connectivity network of socio-ecological systems of the integrated coastal villages. The data collected included primary and secondary data related to social and ecological systems. The data analysis was performed in descriptive-quantitative and descriptive-spatial manners. The results showed that the socio-ecological systems of Blanakan Village, Tanjungtiga Village, Rawameneng Village, and Mayangan Village were composed of resource networks such as fish resources, ecosystem resources, land resources, and water resources used by fishermen, farmers and general public. The sustainable utilization of the resources was supported by the availability of infrastructure provided by the government and the private sector. The connectivity network of socio-ecological ecosystems of the integrated coastal villages showed that the social systems among coastal villages were connected through educational interactions, fishermen institutions, health services, and other interactions, while the interaction of the ecological system was connected through fishing ground networks and the shared utilization of mangrove ecosystems, especially between Blanakan Village and Mayangan Village.

Abstract

Sempor Reservoir is one of the reservoir in Central Java. This reservoir has primary function as irrigation and hydropower source. Beside, it also has some benefit for fisheries and tourism activities. Reservoir utilization which has not been optimum yet need some adjustments with water quality and aquatic trophic state in Sempor Reservoir. This study was aimed to determine water quality and aquatic trophic state of Sempor Reservoir. This study was conducted from January to March 2014 with monthly water sampling. Survey method to collect data with stratified random sampling was used for four represented station. Aquatic trophic state determination was based in Carlson Trophic State Index (TSI) measurement. This method used some represented parameters of physics, chemistry and biology such as water transparency, total phosphorus, and chlorophyll-a. The results showed that water quality of Sempor Reservoir was still good for fishery activities. Aquatic trophic state of Sempor Reservoir based on Carlson TSI was classified to low-medium in euthropic category ranging from 50.71-64.91. Inlet was the only area which had medium category of eutrophic due to highly nutrient content derived from anthropogenic activities nearby.

Abstract

The area of mangrove Segara Anakan has a high economic value so that there is a high interest to various land uses in this area. This condition leads to the change in ecological function of the mangrove which has impacts on the decreased production of mangrove crabs. This study was desighed to analyze the areas of catching crabs related to mangrove ecosystem. This study was conducted for six months in the 3 mudcrab catching areas (Western Area, Central Area, and Eastern Area). The analysis used in this study was a one way ANOVA statistic for the crabs catching in these 3 catching areas, and a simple linear regression to analyxe the correlation betwen annual crab production and mangrove area. The results showsed that mud crabs catchings in the 3 areas is 5861.7; 6072.87; dan 7689.4 kg were significantly different (P<0.05) and the linear regression between the area of mangrove in Segara Anakan and crab?s production of the Cilacap Regency was Y= 14.951X-88357 with R2 = 0.54. These results described that the number of crabs catching was influenced by the condition of mangrove in the 3 catching areas while the regressionb analysis showed that the decreased mud crab?s production in Cilacap Regency was correlated to the decrease in the area of mangrove Segara Anakan.

Abstract

Perairan rawa banjiran Lubuk Lampam (RBLL) merupakan ekosistem khas yang mempunyai arti penting terutama secara ekologi sebagai habitat ikan khas rawa banjiran. Penelitian ini bertujuan untuk mengetahui karakteristik kualitas air di RBLL terkait dengan perubahan muka air dan adanya masukan bahan antropogenik terutama dari kegiatan perkebunan kelapa sawit yang berada di dalam dan sekitar area RBLL. Hasil penelitian ini menunjukkan bahwa curah hujan merupakan faktor utama yang mempengaruhi perubahan muka air di RBLL. Fluktuasi muka air yang tidak ekstrim sebagai akibat dari curah hujan yang relatif merata sepanjang tahun menyebabkan karakteristik kualitas air antar periode musim menjadi cenderung sama. Secara umum, karakteristik kualitas air RBLL dicirikan dengan pH cenderung asam, kandungan oksigen rendah, kekeruhan tinggi serta konsentrasi total nitrogen dan total fosfor yang tinggi. Bahan antropogenik berupa herbisida dari jenis paraquat dan glyfosat ditemukan dalam konsentrasi relatif kecil (rataan 0,004 mg/L dan 0,003 mg/L), sehingga berdasarkan nilai resiko (Risk Quotient, RQ) kedua jenis herbisida ini memiliki resiko ekobiologi rendah (<0,01) sampai dengan sedang (0,01<RQ≤0,1).
