Nitrat dan fosfat adalah unsur nutrien yang menjadi pembatas kelimpahan fitoplankton. Kandungan nitrat dan fosfat di perairan muara akan dipengaruhi oleh faktor biologi, fisika dan kimia perairan, yang menyebabkan timbulnya suatu persebaran. Hal tersebut menjadi permasalahan di Muara Sungai Bodri, Kendal. Tujuan dari penelitian ini adalah untuk mengkaji kandungan nitrat dan fosfat beserta pola persebarannya, serta keterkaitannya dengan struktur populasi fitoplankton sebagai bioindikator kesuburan perairan di Perairan Muara Sungai Bodri, Kabupaten Kendal. Penelitian dilaksanakan berdasarkan metoda observasi dengan pendekatan spatio-temporal. Sejumlah 9 stasiun penelitian dan 3 kali waktu sampling yaitu 30 Juni, 1 September dan 27 Oktober 2018. Kandungan nitrat dan fosfat serta kelimpahan fitoplankton ditetapkan sebagai variabel terikat. Sedangkan parameter fisika dan kimia perairan seperti suhu, salinitas, derajat keasaman (pH), oksigen terlarut, kecerahan dan arus ditetapkan sebagai variabel kontrol. Hasil penelitian menunjukan bahwa kandungan nitrat berkisar 0,49-0,9 mg/l serta kandungan fosfat berkisar 0,01-0,29 mg/l yang menunjukkan bahwa perairan Muara Sungai Bodri, Kabupaten Kendal dalam kondisi subur/eutrofik. Kelimpahan fitoplankton menunjukkan nilai kisaran diantara 2.356 sampai dengan 162.626 sel/l, yang tersusun oleh 5 kelas dan 45 jenis/species dengan pola persebaran berbentuk konvergen yang bertumpu pada stasiun 3 dan 5.

Penaeus monodon is one of the most important farmed crustaceans. Its also known as Asia Tiger Shrimp because its carapace and abdomen are transversely banded with red and white. The use of synthetic antibiotic in aquaculture had caused problems related to health and environmental safety. Chlorella pyrenoidosa and Dunaliella salina are photosynthetic microalgae. Silver nano particle in microalgae C. pyrenoidosa and D. salina had synthesized and showed their growth stability. They offer a potency to be exploited to supported growth and survival of shrimp larvae. The objective of the study was the application of silver nano particle in microalgae C. pyrenoidosa and D. salina on P. monodon larvae. The research methodology was carried out by making microalgae C. pyrenoidosa and D. salina containing silver nano particle and used as feed of shrimp larvae. Observations were made on the growth and survival of shrimp larvae compared to both microalgae and common feed. The results showed that the P. monodon larvae have the higher growth and survival rate with microalgae C. pyrenoidosa at the beginning of their growth compared to D. salina. However, microalgae without nanosilver and common feed showed a better result for growth and activity of shrimp larvae.

Mud crab is one of fishery commodities which is important in Indonesia . The high demand for mud crabs needs to be balanced with the right management strategy, so that the population will not extinction. Penikel Village, Cilacap is one of the fishing villages which catch mud crabs because of the high demand in the big cities such as Jakarta, Bandung and Bali. The purpose of this study is to determine the population and growth patterns of mud crabs in the Panikel Village, Kampung Laut District, Cilacap. The location of the study was determined by purposive sampling. Wadong and bubu are fishing tools to catch mud crabs. Sampling 67 mud crabs was carried out on Juni 2016, after that, measurement of length, carapace width and total weight were carried out. Regression analysis between carapace width and total weight and condition factors were carried out to determine growth patterns. Based on the research, the average value of the S. serrata length was 63.94±11.31 mm while the female one was 70.29±14.57 mm. The average value of carapace width is 92.28±15.51 mm (male) while for female sex was 98.71±18.38 mm. The average weight of S. serrata male crabs was 190.31±118.43 mm, while those of female sex were 210.77±120.93 mm. Furthermore, based on the analysis of the relationship between the length of weight found negative allomatric growth pattern with the value of the condition factor included in the low category both for male sex 0.73-1.93 and for female sex 0.59-1.66. The low condition factor shows that the condition of Segara Anakan waters especially Penikel Village does not support the growth of mud crabs (S. serrata). Kepiting bakau (Scylla serrata) merupakan salah satu komoditas perikanan yang terpenting di Indonesia. Besarnya permintaan kepiting bakau yang tinggi perlu diimbangi dengan strategi pengelolaan yang tepat agar populasi tidak punah.

Strong market demand and uncontrolled exploitation and/or the inadequate management of fisheries have caused many stocks of sea cucumbers to be overexploited. One suggested effort to overcome this problem is sea ranching. Stocking density is the most important consideration in sea cucumber rearing; therefore, this present work is aimed at elucidating the best stocking density for sea ranching of Holothuria atra. H. atra was taken from the Panjang Island, Jepara waters and reared in bottom cages in Teluk Awur waters, Jepara with a density of 30, 20, or 10 individuals per cage measuring 2 m Ã— 2 m Ã— 1.8 m (with bottom area of 4 m2). Stocking times of H. atra were at the initial time of cage installation, the second and the third months after installation. Bottom sediment characteristics (i.e., chlorophyll a, b, phaeophytin, and total carotene) of the sea cucumber habitat and water quality in the cages were measured monthly during the study. The results showed that growth of H. atra fluctuated; low stocking density yielded a higher weight gain than high stocking density did. The highest weight gain was present in the density of 10 individuals/cage in the second stocking month. The highest survival rate of H. atra was seen in the condition of 30 individuals/cage (93%) at the third stocking month, which means that these sea cucumbers were only reared for three months. The highest mortality occurred at a density of 20 individuals/cage with the survival rate being low (45%) at the first stocking time or in the fifth month of rearing. There was fission evidence among H. atra reared in the cages, resulting in smaller organisms. Among the water quality parameters, the concentration of chlorophyll a, b, phaeophytin, and carotene in the sediment fluctuated according to the time of sea cucumber rearing caused by their feeding and bioturbation. The study results suggested to stock H. atra at low density during the second stocking month to get higher growth.

Penggunaan pupuk anorganik yang berlebih dan secara terus menerus memiliki dampak negatif bagi lingkungan dan dapat merusak tanah. Upaya yang dapat dilakukan untuk mengurangi dampak negatif dari pemakian pupuk anorganik yaitu menggantinya menggunakan pupuk organik. Penelitian bertujuan untuk mengetahui pengaruh pemberian volume bioaktivator EM4 yang berbeda dalam pembuatan pupuk serasah Cymodocea serrulata terhadap kadar C-organik, N,P,K dan rasio C/N. Metode penelitian yang digunakan yaitu eksperimental dengan menggunakan rancangan penelitian RAL (Rancangan Acak Rangkap). Hasil penelitian menunjukkan pupuk organik cair Cymodocea serrulata memiliki kandungan C-organik berkisar antara 1,51% hingga 2,65% (nilai tertinggi pada kontrol, terendah pada perlakuan 40 ml EM4), N berkisar antara 0,70% hingga 1,54% (nilai tertinggi pada kontrol, terendah pada perlakuan 60 ml EM4), P berkisar antara 0,26% hingga 0,73% (nilai tertinggi pada perlakuan 40 ml EM4, terendah pada kontrol), K berkisar antara 0,41% hingga 0,58% (nilai tertinggi pada perlakuan 40 ml EM4, terendah pada kontrol), serta rasio C/N berkisar antara 1,6 hingga 2,28 (nilai tertinggi pada perlakuan 60 ml EM4, terendah pada kontrol). Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian bioaktivator EM4 dapat meningkatkan jumlah bakteri sehingga proses degradasi bahan organik dapat berlangsung lebih cepat dan dapat mempengaruhi hasil akhir nilai C-organik, N, P, K, serta rasio C/N.Cymodocea serrulata; Fermentasi; POC; Unsur Hara The excessive and continuous use of inorganic fertilizers has a negative impact on the environment and can damage the soil. Efforts that can be made to reduce the negative impact of using inorganic fertilizers are replacing them with organic fertilizers. The study aimed to determine the effect of giving different volumes of EM4 bio activator in the manufacture of Cymodocea serrulata serasah on levels of C-organic, N, P, K, and C/N ratio. The research method used is experimental by using the RAL research design (Duplicate Randomized Design). The results showed that Cymodocea serrulata liquid organic fertilizer had C-organic content ranging from 1.51% to 2.65% (the highest value was in the control, the lowest was in the 40 ml EM4 treatment), N ranging from 0.70% to 1.54%. (highest value in the control, lowest in the 60 ml EM4 treatment), P ranged from 0.26% to 0.73% (the highest value in the 40 ml EM4 treatment), K ranged from 0.41% to 0, 58% (the highest value in the 40 ml EM4 treatment, the lowest in the control), and the C/N ratio ranged from 1.6 to 2.28 (the highest value in the 60 ml EM4 treatment, the lowest in the control). Based on the results of the study, it can be concluded that the administration of EM4 bio activator can increase the number of bacteria so that the degradation process of organic matter can take place more quickly and can affect the final results of C-organic, N, P, K, and C/N ratios.

Perifiton merupakan sekelompok organisme yang hidup menempel pada permukaan tumbuhan air yang terendam, tidak menembus substrat, diam atau bergerak di permukaan substrat. Perifiton yang menempel pada daun lamun berperan sebagai faktor penunjang produktivitas primer pada ekosistem lamun, namun apabila kelimpahan perifiton terus meningkat maka akan menghambat pertumbuhan lamun karena lamun akan tertekan dan tidak dapat melakukan fotosintesis dengan baik. Penelitian ini bertujuan untuk mengetahui perbedaan pengaruh buangan limbah tambak terhadap kelimpahan perifiton yang menempel pada daun lamun Enhalus acoroides di Perairan Pantai Teluk Awur dan yang tidak ada buangan limbah tambak di Pulau Panjang, Jepara. Penelitian ini menggunakan Metode Line Transek Kuadran. Pengambilan sampel perifiton dilakukan dengan menggunakan metode sapuan dan pengamatan perifiton dilakukan dengan menggunakan metode sensus dengan bantuan Sedgwick-Rafter. Kelimpahan perifiton di Stasiun 1 dan Stasiun 2 berturut-turut 127,51 ind/cm2 dan 86,25 ind/cm2. Kelimpahan tertinggi ditemukan pada Stasiun 1 karena memiliki pengaruh buangan limbah tambak udang yang ditemukan 3 kelas dan terdiri dari 18 genus, sedangkan pada Stasiun 2 ditemukan 2 kelas yang terdiri dari 13 genus. Kelas perifiton yang mendominasi adalah Bacillariophyceae karena kelas ini dapat bertahan dalam kondisi lingkungan yang tidak stabil. Periphyton is a group of organisms that live attached to the surface of submerged aquatic plants, do not penetrate the substrate, remain stationary or move on the surface of the substrate. Periphyton attached to seagrass leaves acts as a primary productivity supporting factor in the seagrass ecosystem, but if the abundance of periphyton continues to increase it will inhibit seagrass growth because the seagrass will be depressed and unable to perform photosynthesis properly. This study aims to determine the effect of pond waste disposal on the abundance of Enhalus acoroides seagrass periphyton in the waters of Teluk Awur and Panjang Islands, Jepara. This study used the Quadrant Line Transect Method. Periphyton sampling was carried out using the sweeping method and periphyton observations were carried out using the census method with the aid of a Sedgwick-Rafter. The abundance of periphyton at Station 1 and Station 2 is 127.51ind / cm2 and 86.25 ind / cm2, respectively. The highest abundance was found at Station 1 because it influenced shrimp pond waste disposal which was found in 3 classes consisting of 16 genera. The dominating class of periphyton is Bacillariophyceae because this class can survive in unstable environmental conditions.
