“…The dominant index shows the values obtained from the five research stations ranging from 0.099 to 0.520, indicating moderate dominance. If 0 < D < 0.5, then the dominance is low; if 0.5 < D < 0.75, then the dominance is moderate; and if 0.75 < D < 1.00, then the dominance is high (Susiana, 2011). The highest dominant index in the embankment is at station 3 and the lowest dominant index is at station 5.…”

Purpose-The purpose of this research is to examine the diversity of macrozoobenthos as well as its relationship with water quality and substrate in the pond culture area. Design/Methodology/Approach-The method of sampling area is on five observation stations by purposive sampling. The research was done indirectly (ex situ) for macrozoobenthic identification at the Ecology Laboratory, Faculty of Mathematics and Natural Sciences. Findings-The fairness/uniformity index obtained from the five research stations ranging from 0.483 to 0.923 indicates a high degree of uniformity. This indicates that the macrozoobenthos biological index at the study site can be used as an indicator that water quality is in good condition and has the potential to be developed into an aquaculture area as well as supporting the success of the shrimp farming as one of the subsystems of the shrimp agribusiness. Research Limitations/Implications-This research can be a source of information for the management and utilization of environment in the research area, so that shrimp harvest can be optimized in the pond farming area. Originality/Value-This research has found that macrozoobenthos included 61 species.

The study aims to determine the type of vegetation that composes mangrove forests and their zoning patterns, to know the composition of mangrove vegetation types and to determine the level of mangrove forest diversity. This study was determined based on the characteristics of the research location ranging from those close to residential areas to those located close to the beach. The method used is systematic sampling which consists of nine observation blocks and each block is divided into four circular research plots. There are 9 types of vegetation that compose mangrove forests in Wambona Village, Wakorsel District, i.e. Avicenna alba BI, Bruguiera hainnessi, Bruguiera gymnorrhiza (L.) Lamk, Ceriops tagal (Perr), Rhizophora mucronata Lamk, Rhizophora stylosa Griff, Sonneratia alba J.E. Smith, Caseolaris sonneratia (L.) Engl. and Bruguiera parviflora (Roxb.) Important Value Index (IVI) of mangrove vegetation in Wambona Village, Wakorsel District namely; 300% for tree level, pole, stake and 200% for seedling level. Diversity of mangrove vegetation types in Wambona Village, Wakorsel District as a whole is in the moderate category (moderate stability) with each tree 1.54, pole 1.57, stake 1.49 and seedling 1.64.

“…Namun kondisi tersebut tidak terjadi pada daerah mangrove rehabilitasi, oleh karena kerapatan mangrove yang tinggi sengaja dilakukan melalui penanaman. Namun demikian, parameter kualitas air relatif berpengaruh terhadap kelangsungan hidup mangrove (Susiana, 2011).…”

“…Mangrove alami berada dekat dengan muara sungai, sementara mangrove rehabilitasi berada relatif jauh dari muara sungai. Keberadaan muara sungai sekitar mangorve berpengaruh terhadap kepadatan gastropoda dan bivalvia yang berasosiasi (Susiana, 2011). Dengan demikian, perombakan bahan organik dalam hal ini nitrat oleh mikroorganisme yang menghasilkan senyawa asam organik berbeda antara kedua lokasi.…”

“…Persentase fraksi liat pada sedimen mangrove rehabilitasi dan alami berkisar antara 11,83-43,03%, persentase fraksi tertinggi ditemukan pada sub-stasiun II mangrove alami. Fraksi sedimen dengan komposisi yang relatif stabil didominasi mangrove jenis Rhizophora stylosa dan Rhizophora mucronata (Susiana, 2011). Selanjutnya dikatakan bahwa persentase fraksi pasir pada mangrove alami dan rehabilitasi berkisar antara 7,18-16,93% tumbuh mangrove jenis Rhizophora sp.…”

Penelitian ini bertujuan menganalisis kualitas air mangrove alami dan rehabilitasi, meliputi DO, salinitas, suhu, pH, nitrat, dan ammonia serta fraksi sedimen. Penelitian dilaksanakan pada Januari hingga Maret 2011 bertempat di estuari Perancak, Bali. Data dianalisis di Balai Riset Observasi Kelautan (BROK) Jembrana, Bali. Pengukuran kualitas air dan fraksi sedimen dibagi kedalam 4 (empat) sub-lokasi pada masing-masing lokasi. Masing-masing sub-lokasi mewakili kondisi dan karakter lingkunga, yakni dekat muara, pertengahan dan jauh dari muara. Pengukuran dilakukan insitu dan laboratorium. Kualitas air dan fraksi sedimen masing-masing zona di analisis secara deskriptif. Hasil penelitian menunjukkan bahwa kondisi kualitas perairan pada daerah mangrove alami memiliki kisaran yang luas (DO antara 1,75-3,54 mg/l, suhu antara 29,08-30,50 oC, salinitas antara 20,16-38,27 ‰, pH antara 7,99-8,13, NO3 antara 0,1391-0,4037 mg/l serta NH4 antara 0,0539-0,1423 mg/l) dibanding pada daerah mangrove rehabilitasi dengan kisaran kualitas air sempit (DO antara 1,85-2,20 mg/l, suhu antara 29,01-29,41 oC, salinitas antara 17,41-22,87 ‰, pH antara 7,86-7,97, NO3 antara 0,1590-0,2693 mg/l dan NH4 antara 0,0857-0,0947 mg/l). Fraksi sedimen pada daerah mangrove rehabilitasi komponen pasir dan liat dalam porsi yang relatif kecil dibanding dengan daerah mangrove alami. Selain itu, komposisi fraksi sedimen pada mangrove alami cenderung lebih stabil dibanding mangrove rehabilitasi cenderung fluktuatif. Perbedaan kualitas air dan fraksi sedimen diduga kuat kuat memperngaruhi truktur dan komposisi mangrove, gastropoda dan bivalvia yang ada di lokasi tersebut. Selain itu, perbedaan tersebut terkait erat dengan kestabilan ekosistem dan keberadaan muara sungai yang diduga turut berpengaruh terhadap kondisi tersebut.
