Abstract

ABSTRAK   Ikan gurami (Osphronemus gouramy) merupakan komoditas ikan air tawar yang bernilai ekonomis penting, tetapi mempunyai kendala didalam budidaya, misalnya pertumbuhannya lambat  dan pemanfaatan pakan yang kurang efisien.  Salah satu pemecahan masalahnya  adalah dengan pemanfaatan probiotik pada pakan  didalam kultur, khususnya pada stadia larva gurame (Osphronemus gouramy). Penelitian ini bertujuan untuk mengetahui dan mengkaji pengaruh penambahan probiotik komersil terhadap pertumbuhan, efisiensi pemanfaatan pakan dan kelulushidupan larva ikan gurame (Osphronemus gouramy). Materi yang digunakan adalah beberapa  produk probiotik komersial yang dicampurkan pada pakan buatan ikan dengan cara disemprotkan dan setelah didiamkan selama 24 jam diberikan sebagai pakan gurame. Metoda eksperimen dan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 kali pengulangan telah dikembangkan pada penelitian ini. Perlakuan yang diujikan adalah tanpa pemberian probiotik pada pakan (A); pemberian probiotik 1 (B); pemberian probiotik 2 (C); dan perlakuan D dengan pemberian probiotik 3 pada pakan. Berat benih gurame (Osphronemus gouramy) per individu 1,86±0,97 g dan panjang 4,11±0,41 cm. Padat penebaran benih gurame pada perlakuan yaitu 2 ekor/liter. Benih gurame diberi makan 3 kali sehari sebanyak 5% dari bobot biomassa. Hasil penelitian menunjukkan bahwa penambahan probiotik pada pakan memberikan pengaruh nyata (P<0,05) terhadap pertumbuhan dan efisiensi pemanfaatan pakan, tetapi tidak berpengaruh nyata (P>0,05) terhadap kelulushidupan benih ikan gurame. Hasil terbaik diperoleh pada pemberian probiotik 1 dengan nilai tingkat pertumbuhan spesifik (SGR) sebesar 1,67±0,42 %,  efisiensi pemanfaatan pakan (22,2±2,6%) dan kelulushidupan (85,0±5,6%). Kriteria kualitas air media kultur masih baik untuk mendukung proses pertumbuhan dan pemanfaatan pakan.   Kata kunci : Probiotik komersial, pakan buatan, gurame (Osphronemus gouramy), dan pertumbuhan   ABSTRACT   Gouramy (Osphronemus gouramy) is  freshwater fish commodity that have high economic value, but it have problems in the culture such as the slow growth and inefficiency of feed utilization.  One of the problem solves is utilization of probiotic bacteria in the artificial feed, especially for fish larvae culture. The purpose of this study was to know and observe the effects of adding commercial probiotics for growth, feed utilization eficiency and survival rate of gouramy (Osphronemus gouramy) from day 35  to day 75. Some commercial probiotics used were sprayed onto artificial feed and after incubated during 24 hours, then give as fish feed in the culture. The experimental methods with completely randomized design (CRD) were employed in this research. The design consisted of 4 treatments and 3 replication, respectively. The treatments tested were without  probiotic added (treatment A), with probiotic 1 (B), with probiotic 2 (C), and the treatment D with added by probiotic 3. The initial density of  fish larvae were 2 inds/liter of water medium with average weight of 1,86 ± 0,27 g and length of 4,15±0,35 cm.  Gouramy fish were fed three times every day with 5% from biomass weight. The  research results shown that the difference adding probiotics in the artificial feed were significantly effects (P<0.05) on the growth and feed utilization efficiency but no significantly effect (P>0,05) on the survival rate of  gouramy (Osphronemus gouramy) in the culture. The best result was in the treatment B (with added by probiotic 1), where  the  best SGR of 1,67±0,42 %,  feed utilization efficiency of 22,2 ± 2,6% and survival rate of  85,0 ± 5,6%.  The water quality criteria of  culture medium were the good supported to the growth, feed  utilization, and survival rate of Gouramy (Osphronemus gouramy) in the culture.  Keywords : Commercial probiotic, artificial feed, Gouramy (Osphronemus gouramy), and growth

Abstract

 Tekstur sedimen terdiri atas fraksi pasir (sand), lumpur (silt), dan liat (clay). Sedimen atau substrat dasar yang terus menerus menumpuk serta adanya bawaan nutrien dari mahluk hidup maupun limbah akan membentuk kandungan bahan organik. Kandungan nutrien digunakan oleh makrozoobenthos sebagai salah satu kebutuhan pakan untuk kelangsungan hidup makrozoobenthos. Selain itu, makrozoobenthos ditemukan hidup dalam sedimen. Jenis tekstur sedimen serta kandungan fraksi mempengaruhi kelimpahan makrozoobenthos itu sendiri. Tujuan dari penelitian ini adalah untuk mengetahui jenis tekstur sedimen, kandungan bahan organik, kelimpahan makrozoobenthos, dan hubungan ketiga variabel. Penelitian ini menggunakan metode deskriptif. Jenis tekstur pada setiap stasiun didominasi oleh lempung. Jenis makrozoobenthos yang didapatkan berasal dari famili Ciratulidae, Nephtydae, Nereidae, Tubificidae dan Arcidae. Berdasarkan hasil penelitian dapat disimpulkan bahwa hubungan antara ketiga variabel yang diamati adalah semakin besar persentase lempung, maka diikuti pula oleh kandungan bahan organik dan melimpahnya makrozoobenthos.  Sediment Texture consists of sand, silt, and clay. Sediment cumullation and transport nutrient from organisms and domestic waste will make organic matter. Nutrient was used by macrozoobenthos as feeding is needed to survive. Moreover, macrozoobenthos was found in sediment itself. Sediment texture and fraction contain were influencing the abundance of macrozoobenthos.This research was aimed to know kinds of sediment texture, organic matter contain, the abundance of macrozoobenthos, the relationship among sediment fractions with organic matter and macrozoobenthos in the estuary of Banjir Kanal Timur Semarang.

Abstract

Perairan Ujung Kartini merupakan perairan yang menjadi muara dari Sungai Wiso dan Sungai Kanal yang terletak di sisi barat Kabupaten Jepara. Di sekitar Perairan Ujung Kartini terdapat kegiatan manusia yang dikhawatirkan dapat menyebabkan perubahan kualitas air terutama kandungan unsur hara. Perubahan kandungan unsur di perairan akan berdampak terhadap persebaran dan kelimpahan fitoplankton serta konsentrasi klorofil-a. Penelitian ini bertujuan untuk mengetahui tingkat kesuburan perairan dan hubungan antara kelimpahan fitoplankton dengan konsentrasi klorofil-a. Penelitian dilakukan pada bulan November dan Desember 2017. Penelitian ini termasuk jenis penelitian analisis deskriptif dan penentuan lokasi sampling menggunakan metode purposive sampling. Pengambilan sampel air dan fitoplankton dilakukan di tiga stasiun yang ditentukan berdasarkan tinggi rendahnya kegiatan manusia. Pengambilan sampel tersebut dilakukan pada saat kondisi pasang dan surut dengan dua kali pengulangan. Hasil penelitian yang diperoleh menunjukan bahwa kelimpahan fitoplankton pada saat pasang dan surut berkisar antara 6.375 – 13.725 sel/l dan konsentrasi klorofil-a pada saat pasang dan surut berkisar antara 0,126 – 1,392 mg/m3. Nilai diatom quotient sebesar 1,533 yang berarti perairan yang diteliti termasuk ke dalam kategori perairan eutrofik. Kelimpahan fitoplankton dan konsentrasi klorofil-a pada saat pasang lebih tinggi daripada saat surut. Keduanya mempunyai hubungan yang sangat erat. Ujung Kartini Waters is part of the estuary of the Wiso River and Kanal River which are located on the west side of Jepara Regency. In the surrounding area, there are human activities that are feared to cause changes in water quality, especially nutrient content. Changes in nutrients content in the waters will have impact on the distribution and abundance of phytoplankton and concentration of chlorophyll-a.  This study aims to determine the level of aquatic productivity and the relationship between phytoplankton abundance with chlorophyll-a concentration. The study was conducted from November to December 2017. This research includes descriptive analysis and determination of sampling location using purposive sampling method. Samples of water and phytoplankton were collected at three stations based on the level of human activity. Sampling was carried out during high tide and low tide with two repetitions. Based on the results of the research, the abundance of phytoplankton at high and low tides ranged between 6.375 - 13.725 cells/l and chlorophyll-a concentrations at high and low tides ranged between 0,126 – 1,392 mg/m3. The value of diatom quotient is 1,533 which means that the waters of study area belong to the eutrophic category.

Abstract

Bagan perahu merupakan salah satu jenis alat tangkap di PPN Karangantu yang beroperasi pada malam hari. Bagan perahu menarik ikan target tangkapan yaitu ikan pelagis kecil fototaksis positif menggunakan atraktor cahaya berupa lampu. Salah satu kendala nelayan bagan perahu adalah pencahayaan lampu mengalami pembiasan. Penggunaan lampu bawah air bertujuan untuk mengurangi pembiasan. Tujuan dari penelitian ini adalah mengetahui pengaruh penggunaan lampu bawah air terhadap hasil tangkapan bagan perahu dan mengetahui komposisi hasil tangkapan bagan perahu dengan dan tanpa lampu bawah air. Penelitian ini dilakukan selama 10 trip menggunakan metode experimental fishing. Selisih berat total hasil tangkapan antara bagan perahu dengan dan tanpa lampu bawah air pada trip 1 sebesar 33,4 kg, trip 2 sebesar 38,9 kg, trip 3 sebesar 31,1 kg, trip 4 sebesar 41,1 kg, trip 5 sebesar 28,8 kg, trip 6 sebesar 30,5 kg, trip 7 sebesar 35,4 kg, trip 8 sebesar 34,3 kg, trip 9 sebesar 38,7 kg dan trip 10 sebesar 31,6 kg sehingga menunjukkan hasil tangkapan lebih banyak bagan perahu dengan lampu bawah air. Hasil tangkapan utama bagan perahu adalah ikan Teri (Stolephorus sp.) dan Cumi-cumi (Loligo sp.). Hasil tangkapan sampingan bagan perahu antara lain ikan Petek (Leiognathus sp.), Tembang (Sardinella sp.), Lemuru (Amblygaster sirm), Selar Kuning (Selaroides leptolepi) dan Layur (Lepturacanthus savala). Kesimpulan yang dapat diambil yaitu terdapat pengaruh antara lampu bawah air dengan hasil tangkapan pada bagan perahu. Boat lift net is one type of fishing gear at PPN Karangantu which operates at night. Boat lift net attracts the target catch fish, the small pelagic fish is positive phototaxis using a light attractor in the form of a lamp. One of the constraints of fishermen on the boat chart is that the lighting has experienced refraction. Underwater lamp aims to reduce refraction.The purpose of this research is to know the effect of underwater lamp usage on boat lift net fishing catch and to know the composition of boat lift net with and without using underwater lamp. This research was conducted for 10 trips using experimental fishing methods. The difference in total catch of boat lift net with and without underwater lamp on trip 1 is 33,4 kg, trip 2 is 38,9 kg, trip 3 is 31,1 kg, trip 4 is 41,1 kg, trip 5 is 28,8 kg, trip 6 is 30,5 kg, trip 7 is 35,4 kg, trip 8 is 34,3 kg, trip 9 is 38,7 kg and trip 10 is 31,6 kg so it shows the catch is more the boat lift net with underwater lamp. Fish targets of the boat lift net are Anchovy (Stolephorus sp.) and Cuttlefish (Loligo sp.). The bycatches of boat lift net are Pony fish (Leiognathus sp.), Fringescale sardinella (Sardinella sp.), Indian sardinella (Amblygaster sirm), Trevally (Selaroides leptolepi) and Hairtail fish (Lepturacanthus savala).
