Abstract

This study aims to determine how much water hyacinth absorbs pollution, effectiveness and howsignificant the difference in pollution in crude oil waste after and before planting waterhyacinth. The sample tested in this oil waste is NH3, pH of oil and fat. The research design usedwas a randomized block design (RBD) of 5x1 with 3 replications with variations in theconcentration of crude oil waste consisting of 5 dilution treatments, namely: P0 (100%), P1(75%), P2 (50%), P3 (25%) and P4 (0%) and observed for 21 days. Data from the researchresults were analyzed using Microsoft Excel software to test the value of efficiency. The resultsof the study after phytoremediation of water hyacinth were able to reduce NH3 content, pH ofoil and fat. Water hyacinth can absorb contamination caused by crude oil waste effectively. It isproven that during the phytoremediation process NH3 content in crude oil waste decreasesbelow the water quality standard, in oil and fat parameters it can fall below the water qualitystandard except treatment P4. Water hyacinth can reduce NH3, pH Oil and fat in crude oilwaste are significant.

Abstract

Plankton is organisms that had an important role in water as natural feed of fishes and as an indicator. This study aimed to identify water quality which was suitable for fish cultivation reviewed from physics-chemicals parameters of water and its saprobic status in Tambak Lorok Tanjung Mas Kota Semarang. Sampling were take based on 5 stations that could represented from plankton variety of condition water stability . Plankton samples were by using net plankton number 25, then preserved with alcohol 70% and formalin 4%. Variables of ponds water quality measured were temperature, salinity, dissolved oxygen, pH, turbidity, N concentration, and Pb content. Identification of planktons used SRC method under microscop. The result of plankton analysis in Tambak Lorok water showed 42 phytoplankton species, the commonly species found are Coscinodiscus centralis, Coscinodiscus granii, Gyrosigma sp., Navicula radiosa, Pandorina sp., and Melosira sp. Meanwhile, zooplankton found was 22 species with common species are Cyclops, Harpaticoida, Tricodesmium evythraeum, Brachinus plicatilis, and Lensia subtilis. Phytoplankton diversity index are 0.057-0.367 and equity index are 0.025-0.176. Zooplankton diversity index are 0.247-0.360 and equity index are 0.157-0.201. This indices showed that there were low level of species diversity and community stability, dominance since the species occurred. Measurement of water quality variables indicated that Tambak Lorok had been contaminated and needed a preliminary management before d be used as fish cultivation ponds, because the analysis result was not appropriate with Government water quality  regulation. Based on the measurement, soprobic index categories on α/β-Mesosaprobic to Oligosaprobic phase and the degree of pollution is very mild to moderate. Keywords :  Community Structure, plankton, Tambak Lorok, Tanjung Mas, Semarang

Abstract

Milkfish is one of the main commodities in the field of fishery and is known to be the most cultivated. One of the important’s factors to the success of milkfish cultivation is feed availability, both quality and quantity. Feed quality is an important aspect that must be fulfilled because of its relation to nutrients required for the fish growth. Azolla pinnata has a good potential that can be used as an additional ingredient for the fish growth because of its protein-rich content. This study is aimed to examine the effect of Azolla pinnata powder feed on growth of milkfish (length and body weight). This research was conducted in May – July 2017 at Aquatic Animal Health Management Laboratory, Center of Brackish Water Aquaculture of Jepara. The research design used is a Complete Randomized Design (CRD), using five treatments with different concentrations of Azolla pinnata powder, i.e. 0% as control, 10%, 20%, 30%, and 40%. Each treatments consist of three repeatitions. The parameters observed were milkfish growth (length and body weight) and dissolved oxygen (DO). Data were analyzed by Analysis of Variance (ANOVA) method. If the data showing significant differences it will be continued with Least Significance Different (LSD) test. The results showed that the administration of Azolla pinnata powder on the feed significantly influenced the growth (lenght and body weight) of milkfish. The most optimal and efficient feed composition for milkfish growth is done by feeding 40% of Azolla pinnata powder. The overall dissolved oxygen (DO) is still in suitable condition for the cultivation of milkfish. Key Words :  Azolla pinnata, dissolved oxygen, feed nutrition, milkfish

Abstract

The breakwater of Tanjung Emas Seaport is designed to absorb seawave as well as increase ships stability.Such water stability will trigger the light and small particles to deposite onto the bottom of the water body,eventhough these are easily re-suspended and initiate to create turbidity. Turbididty is one factor affecting Mollusccommunity. In facing the global climate changes, there will be a seriuos problem triggering the turbidity of theseawater and so do the organims. Researh were aimed to study the benthic Mollusc community in different turbiditylevels. Justified ramdom sampling was applied in 14 stations. Community structure of the molluscs were analizeddiscriptively as well as through Shannon-Wiener (H’) and evenness (e) indeces.Result showed that turbidity in PTES varies between 06,750 – 45,250 NTU. Such qualities were relativelyhigh range and can be tolerated by several given species, mainly Gafrarium tumidum, Nuculana acuta and Pyrenesp. These three above species could live within such high turbidity levels, since some of material are part of theirdiets without disturbing their respiration fuction. The highest diversity index H’ was 1,68 and found in Station 5,which is in accordance with its highest turbididyt level 45,250 NTU. The smalest turbidity level occured in Station 8and it was related to smaller diversity index (0,24). There was a tendency, the smaller the turbidity levels the smallerthe diversity indices. Such relatonship was consistence to the other three stations, namely 9,10 and 11. Exceptionwas found in Station 1, where different dominant species occured and diversity index was relatively high. It isbelieved these are related to the presence of warm outlet of Indonesia Power sewage reaching 32,5 centdegree.

Abstract

Wideng merupakan biota asosiasi hutan mangrove yang sangat penting perannya dalam degradasi serasah mangrove.Wideng mempunyai perilaku membuat lubang pada pematang yang merugikan petani. Sementara pada sisi yang lain, secara fisik hutan  mengrove banyak didapati sampah plastik yang berasal dari hulu. Keberadan sampah sangat mengganggu kehidupan bakau maupun biota asosiasinya, terlebih aktifitas pariwisataPerlu dilakukan pengelolaan untuk mengendalikan wideng di tambak, sekaligus mendorong tercapainya estetika kawasan  mangrove yang mendukung Ekowisata. Tujuan umum penelitian adalah memanfaatkan sampah plastik sebagai penguat tanggul tambak yang tahan pelubangan wideng (Sesarma sp) untuk mendukung ekowisata mangrove. Hal ini dilakukan dengan mengkajiadanya dinamika spasial populasi Sesarma spp dan makrobentos asosiasi dan tingkat kesukaan substrat (pematang) yang diberi alas berbagai bahan.Kajian  observasi dilakukan secara sampling dengan analisis Struktur Komunitas. Adapun kajian pelubangan menggunakan RAL dengan uji lanjut t-test. Hasil sampling makrobentos di jumpai 16 jenis dengan jenis yang umum ditemukan adalah Cerithidea spp, Neries spp dan Sesarma sp.Sesarma sp cenderung mengikuti keberadaan bahan organik, terutama bahan serasah mangrove. Pada perlakuan penguatan pematang menggunakan bahan sampah memperlihatkan pematang yang disisipi bahan serasah cenderung disukai wideng,  diikuti bahan sampah plastik dan bahan plastik lembaran. Secara praktek, petambak sebaiknya memungut sampah untuk dimanfaatkan sebagai penguat dengan menyisipkannya pada lumpur bahan tanggul. Prioritas lokasi yaitu di muara tengah dan depan yang banyak ditemukan wideng dan serasah. Mekanisme pelaksanaan penguatan tanggul dapat difasilitasi oleh kelompok tani. Luaran penelitian disamping tanggul menjadi kuat, tidak menarik bagi wideng, kawasan menjadi bersih, juga tidak perluperlu memotong ranting mangrove untuk digunakan sebagai aran (landasan lumpur).   Kata Kunci :Wideng, perusak tanggul, sampah plastik

Abstract

Reboisation is one strategy to anticipate global warming that most easily performed. This re-plantingactivity is very urgent to be conducted in mangrove areas, since the impact of global warming are very profound atthe coastal and lowland areas. Its implementation has been done, but failures are still high. One of the causes oftenfound in the field is pests. Its efficient and effective control are still faces various obstacles. Wideng (Sesarma) isvery often perform as pest to the mangrove propagules, therefore could affect the community structure. It is thereforeimportant to establish conceptual study and research on wideng control, especially those that are able to promoteparticipation and benefit the community. One potential control is to empower its natural predators, the mud crabScylla. The purpose of this research is to analyze the level of Scylla predation, namely of total prey consumed, preysize and prey density presentation. It is also intended to determine weight gain and predation behavior byScylla. Two units of the test cage were placed in the pond in Tapak Tugurejo Semarang with Complete RandomizedDesign (3 treatments and 5 replications). Data on predation tests are descriptively and statistically analyzed usingJMP software, whereas the study of behavior was analyzed descriptively.The results demonstrated that Scylla is able to prey and consume wideng namely the life ones. Scyllaperform no respecter of prey body size, since wideng of small body size (2-3 cm), preferably the same to themoderate size (4-5cm) and large size (> 5 cm). The level of consumption gives a high weight gain for Scylla,between 182 - 197% in just 6 days. In term of presentation of the treatment, showed that wideng really liked thepresentation of the feed lot at once rather than presenting a slightly but gradually. Finally, feeding on Scylla withwideng through cultivation, particularly in fattening purposes, using wideng is reasonable and flexible to be appliedfor fishermen. This concept, together with other control components (components of a dissertation study of theauthor), is very supportive on the wideng control whiles provide economic benefits to the society atonce.

Abstract

Kondisi kerusakan hutan mangrove sudah sangat memprihatinkan. Gangguan hama wideng (Sesarma spp) mempengaruhi keberhasilan penghijauan. Wideng merupakan hama minor yang dapat bergeser sifatnya jika populasinya tinggi pada kondisi tertentu. Oleh karena itu perlu dilakukan penelitian tentang dinamika populasi wideng, sehingga dapat mengetahui waktu kapan wideng berpotensi menjadi hama. Kajian yang sama juga ditujukan terhadap pemangsa potensialnya yaitu Scylla yang ditujukankan untuk mengetahui tekanan  predator terhadap wideng dan peluang pemberdayaannya sebagai pakan budidaya. Penelitian bersifat observasional yang dilakukan di kawasan mangrove Tapak, Tugurejo. Sampling dilakukan di enam stasiun yang dipilih secara justified random sampling. Kajian eksperimental menggunakan Rancangan Acak Lengkap(RAL) dengan tiga perlakuan dan tiga ulangan yang dilanjut dengan uji Beda Terkecil. Hasil memperlihatkan bahwa populasi wideng mengikuti pola unimodal dengan puncak populasi pada bulan Nopember mencapai 30/m2.Kepiting Scylla memasuki musim tangkap sejak Oktober hingga Maret dan mencapai puncaknya pada bulan Pebruari. Kepadatan populasi tersebut selaras dengan keberadaan wideng yang juga tinggi populasinya, sehingga dapat dipergunakan sebagai pakan budidaya sekaligus menekan sifat hamanya.Kepiting bakau menyukai wideng pada semua ukuran, dimana tidak membedakan ukuran badan wideng mangsanya  pada hari ke-5, meskipun pada hari ke-3 memperlihatkan kecenderungan menyukai ukuran badan yang kecil; sehingga wideng bersifat fleksibel sebagai pakan budidaya Scylla.   Kata kunci : Dinamika populasi, wideng, Scylla spp, tingkat predasi
