"Ketahanan sosial-ekologi adalah kemampuan penyintasan masyarakat dalam menghadapi keterbatasan lingkungan agar dapat pulih apabila terjadi gangguan. Meskipun keterbatasan lingkungan alam dan sosial di Kota Batam dapat dikelola dengan kemajuan teknologi, potensi gangguan tetap perlu diperhitungkan agar perikehidupan dan kesejahteraan masyarakat tetap terjamin.Riset ini bertujuan untuk mengkonstruksi model ketahanan sosial-ekologi dalam pembangunan berkelanjutan. Pendekatan riset menggunakan metoda gabungan dengan pendekatan kualitatif terkait kondisi ketahanan sosial-ekologi Kota Batam yang dianalisis menggunakan sarana Kualitas Kehidupan Sosial Budaya berbasis fuzzy logic interaksi antara elemen struktural, kultural dan prosesual berkenaan dengan capaian pembangunan.Hasil penelitian menunjukkan bahwa kondisi ketahanan sosial-ekologi sangat terkait dengan dinamika lokal, regional dan global; spesifikasi dan spesialisasi lingkungan setempat, karakteristik region, serta faktor-faktor sosial budaya yang berpengaruh dalam menentukan kekhasan lingkungan yang menentukan ketahanan sosial-ekologi. Kondisi ketahanan sosial-ekologi juga dapat bervariasi secara spasial dan menurut waktu sehingga model konseptual ketahanan sosial-ekologi perlu mengakomodasi strategi implementasi yang bersifat multicompartment sekaligus terintegratif.......Social-ecological resilience is the community’s surviving ability to face environmental limitations and possible disruptions. Although physical and social environmental limitations in the City of Batam can be managed with technological advances, the potential of disruptions should be taken into account to assure the good community’s livelihood and welfare.This research is to construct a social-ecological resilience model in sustainable development. It is based on mixed method research with qualitative approach on the social-ecological resilience condition of the City of Batam; that is analyzed based on the Quality of Socio-Cultural Life that seeks through the fuzzy-logic-interaction between structural, cultural and processual elements on the results and transformation of development.The results show that the social-ecological resilience condition is related with dynamics of local, regional and global conditions, local environment specifications and specializations, regional characteristics, as well as socio-cultural factors that determine the social-ecological resilience condition that can vary spatially and according to time. Therefore, the conceptual model of social-ecological resilience in sustainable development should accommodate multi-compartment and integrative strategy of implementation.

"Penelitian penggunaan rumput laut sebagai fitoremediasi limbah budidaya udang vanamei adalah salah satu upaya untuk mengatasi pencemaran perairan dan kerusakan lingkungan yang diakibatkan oleh kegiatan budidaya udang. Penelitian ini menggunakan pendekatan kuantitatif, dengan 3 jenis rumput laut sebagai kandidat fitoremediasi yaitu: Caulerpa sp, Gracilaria sp dan Eucheuma sp. Tempat pelaksanaan penelitian adalah Kampus Sekolah Tinggi Perikanan desa Karangantu, Kec. Kasemen Kota Serang Propinsi Banten. Hasil penelitian menunjukkan bahwa Gracilaria sp memiliki kemampuan biofiltrasi lebih tinggi dibandingkan Caulerpa sp dan Eucheuma sp yaitu kemampuan menyerap limbah organik budidaya udang vanamei baik amonia, nitrit, nitrat dan total bahan organik. Nilai rata-rata tingkat biofiltrasi Gracilaria sp terhadap amonia, nitrit, nitrat dan total bahan organik secara berturut-turut sebesar 36,3 , 20,1 , 30,8 dan 14. Hasil uji skala lapangan menunjukkan bahwa penggunaan rumput laut juga mampu meningkatkan pertumbuhan udang dan kualitas air budidaya. Rata-rata pertumbuhan udang vanamei mencapai 0,3 g/hari dengan tingkat kelangsungan hidup berk isar antara 75-85 . Produktivitas hasil panen udang vanamei berkisar 3,8-4,5 kg/m2 dengan size 53-63 ekor/kg. Kualitas air selama kegiatan budidaya berada dalam kisaran normal dan jauh lebih baik dibandingkan dengan kualitas air di tambak konvensional. Persepsi masyarakat terhadap teknologi fitoremediasi memiliki nilai cukup baik. Teknologi ini diyakini oleh masyarakat memiliki manfaat secara ekologi, ekonomi dan sosial. Bertambahnya nilai manfaat limbah berdampak positif terhadap pemakaian sumberdaya yang lebih efesiensi.

AbstractTo overcome environmental pollution and degradation from shrimp farming activities, research on the use of seaweeds for phytoremediation is necessary and gaining momentum. This research employed quantitative approach, with 3 types of seaweed are used as the phytoremediation candidate, namely Caulerpa sp, Gracilaria sp and Eucheuma sp. The research took place at the Jakarta Fisheries University Campus - Karangantu station, Banten. The results showed that Gracilaria sp has higher biofiltration ability than Caulerpa sp and Eucheuma sp, including the ability to absorb organic waste either ammonia, nitrite, nitrate or total organic matter from vanamei shrimp culture. The average biofiltration rates of Gracilaria sp on ammonia, nitrite, nitrate and total organic matter were 36.3 , 20.1 , 30.8 and 14 , respectively.

Field trial indicated that the use of seaweed can also increase shrimp growth and improve water quality. The average growth of shrimp reached 0.3 g/day, with survival rate ranging from 75 to 85 . Productivity of vanamei shrimp ranged from 3.8 to 4.5 kg/m2, with the size of 53-63 heads/kg. During the trial, water quality was within the normal range and much better when compared to that of the conventional pond. Public perception on phytoremediation technology appeared to be "good". This technology is believed to possess ecological, economic and social benefits. Increase value of waste benefits would positively affect the utilisation of resources in a more sustainable way."
