ABSTRAK Muara Sungai Cipasauran merupakan ekosistem yang dimanfaatkan oleh masyarakat setempat untuk kegiatan rumah tangga. seperti mandi, mencuci pakaian dan kegiatan nelayan. Aktivitas kegiatan tersebut menyebabkan masuknya air limbah ke saluran air sungai lainnya. Hilir Cipasauran Muara, berakhir di Pantai Anyer. Kegiatan penangkapan ikan di sekitar Pantai Anyer menunjukkan kualitas air yang relatif baik. Tujuan dari penelitian ini adalah untuk menentukan sebaran bakteri heterotrofik, bahan organik total, nitrat dan klorofil-a, serta untuk mengetahui hubungan antara variabel. Bahan yang digunakan dalam penelitian ini adalah air sampel dari 4 lokasi di muara Cipasauran ke Pantai Anyer. Penelitian ini menggunakan teknik purposive sampling. Pengambilan sampel dilakukan dengan interval dua minggu, masing-masing dengan dua kali pengulangan. Hasil penelitian menunjukkan bahwa jumlah bakteri heterotrofik  di empat stasiun berkisar antara 250-2500 cfu/ml, kandungan bahan organik jumlah berkisar 27,83-100,64 mg/l, konsentrasi nitrat berkisar antara 4,12-11,8 mg/l, dan klorofil-a pada empat stasiun berkisar 0,01- 6,31 mg/m3. Muara Sungai Cipasauran termasuk dalam kategori perairan yang subur (Eutrofik). Analisis regresi berganda memperlihatkan bakteri heterotrof signifikan pada bahan organik total (0,02< p<0,05). Adapun, ekstrak klorofil-a yang dihasilkan dari fitoplankton lebih tergantung kepada kadar nitrat (0,03<p< 0,05) dibandingkan terhadap kadar bahan organik total (0,11>p>0,05), sehingga unsur hara yang lebih banyak dibutuhkan adalah nitrat. Namun tingginya nitrat dapat memicu terjadinya eutrofikasi.  Kata Kunci : Bakteri Heterotrof; Bahan Organik Total; Nitrat; Klorofil-A; Muara Sungai Cipasauran ABSTRACT Cipasauran estuarine ecosystems utilized by local communities for household activities, such as bathing, washing clothes and fishing activities. These activities led to an influx of wastewater into waterways of the river. Downstream Cipasauran Estuary, ends at Anyer Beach. Fishing activities around Anyer Beach indicates the relatively good water quality. The purpose of this study is to determine the distribution of heterotrophic bacteria, total organic material, nitrate and chlorophyll-a, as well as to study the relationship between those variables. The material used in this study is water sampled from 4 location, at the estuary of Cipasauran down to Anyer Beach. The study used purposive sampling technique. Sampling was conducted at intervals of two weeks, each with two replication. The results showed that number heterotrophic bacteria in four stations ranged between 250-2500 cfu/ml, where as total organic materials ranged from 27.83 to 100,64 mg/l, nitrates ranged from 4.12 to 11.8 mg/l, and  chlorophyll-a at four stations ranged from 0.01 to 6.31 mg/m3. Cipasauran estuarine included in the fertile waters (Eutrofik). Regression analysis showed a significant increase in heterotrophic bacterial organic matter total (0.02<p<0.05). So, extract the chlorophyll-a resulting from more phytoplankton depend on nitrate levels (0.03<p<0.05) compared against the total organic material levels (0.11>p>0.05), so the more nutrient elements needed is nitrate. But high nitrate can trigger the onset of eutrophication.                Keywords: Heterotrophic Bacteria, Total Organic Material, Nitrate, Chlorophyll-a Cipasauran Estuary

 Pesisir selatan Jawa, khususnya pantai Pagak, Kabupaten Purworejo merupakan daerah potensial dengan beragam jenis biota yang seringkali dimanfaatkan masyarakat setempat sebagai bahan makanan. Biota tersebut diantaranya adalah yutuk (undur-undur laut) yang bermanfaat secara ekologis maupun ekonomis, namun pemanfaatan belum optimal. Penelitian ini bertujuan untuk mengetahui kelimpahan dan pola sebaran undur-undur laut sebagai dasar pemilihan daerah penangkapan undur-undur laut dan hubungan salinitas substrat dengan kelimpahan undur-undur laut yang ada di pantai Pagak, Kabupaten Purworejo. Penelitian dilakukan pada bulan Januari 2018. Pengambilan sampel biota dan substrat dilakukan pada tiga stasiun dimana setiap stasiun dilakukan tiga kali pengulangan pada hari yang berbeda. Pengambilan sampel menggunakan teknik purposive sampling. Hasil penelitian menunjukkan kelimpahan undur-undur laut (hippidae) di pantai Pagak berkisar 2-4 individu/m2 dengan pola sebaran yang mengelompok. Kelimpahan tersebut cenderung lebih tinggi pada salinitas substrat kisaran 33-35 ppt. Salinitas substrat berpengaruh terhadap kelimpahan undur-undur laut (hippidae) di pantai Pagak dan keduanya mempunyai hubungan yang lemah (r = 0,371). Southern coast of Java, especially Pagak beach, Purworejo Regency is a potential area with various types of biota that are often used by local people as food. One of the biota is mole crab that is useful ecologically and economically, while the existing utilization is not yet optimal and sustainable. The purpose of this research is to know the abundance and distribution pattern of mole crab as the basis for the selection of good and sustainable fishing areas of mole crab, and the relationship between substrate salinity and the abundance of mole crab at Pagak beach, Purworejo Regency. The study was conducted in January 2018. Samples collection of biota and substrate were conducted at three stations where each station was carried out with three replication on different days. Purposive sampling technique was used to take the sample. The results showed the abundance of mole crab (hippidae) at Pagak beach ranged from 2 to 4 individuals / m2 with a group pattern of distribution. The abundance tends to be higher in the substrate salinity of 33-35 ppt range. Substrate salinity and abundance of mole crab have weak relationships
