Mikroalga adalah tumbuhan tingkat rendah yang memiliki klorofil untuk melakukan fotosintesis (Rismiarti dkk., 2016). Beberapa spesies mikroalga di alam merupakan pakan alami bagi ikan dan udang. Pakan alami menjadi sumber nutrisi penting pada stadium awal perkembangan organisme. Salah satu pakan alami yang digunakan untuk budidaya ikan yaitu Chlorella sp.. Chlorella sp. memiliki kandungan nutrisi protein sebesar 51–58%, minyak sebesar 28-32%, karbohidrat 12-17%, lemak 14-22%, dan asam nukleat 4-5% (Rachmaniah dkk., 2010).Salah satu cara untuk memperoleh biakan murni Chlorella sp. agar dapat memenuhi ketersediaan pakan alami dalam jumlah yang cukup, berkesinambungan dan tepat waktu adalah dengan adanya tindakan kultur. Praktek Kerja Lapang ini dilaksanakan di Balai Perikanan Budidaya Air Payau (BPBAP) Situbondo, Jawa Timur pada tanggal 23 Januari sampai tanggal 23 Februari 2017. Tujuan praktek kerja lapang ini adalah untuk mendapatkan pengetahuan tentang teknik kultur Chlorella sp. skala laboratorium dan intermediet. Metode kerja yang digunakan yaitu metode deskriptif. Metode tersebut meliputi wawancara, observasi, dan partisipasi aktif selama proses kegiatan kultur Chlorella sp. skala laboratorium dan intermediet. Data yang terkumpul terdiri atas data primer dan sekunder. Kegiatan kultur Chlorella sp. skala laboratorium dilakukan dengan metode kultur bertingkat di dalam ruangan (indoor). Kultur Chlorella sp. dimulai dengan persiapan alat dan bahan (sterilisasi), pembuatan pupuk Walne dan vitamin, isolasi Chlorella sp. pada Petridish (media agar), kultur pada test tube 10 ml, kultur pada Erlenmeyer 250 ml, kultur pada Bottle glass 3 liter, dan kultur pada Carboy 10 liter. Kegiatan kultur Chlorella sp. skala intermediet dilakukan dimulai dengan persiapan alat dan bahan (sterilisasi), pemberian bibit Chlorella sp. yang berasal dari kultur murni skala laboratorium. Pemeliharaan Chlorella sp. dilakukan selama kurang lebih 5 hari yang mencapai fase eksponensial pada hari ke 4. Pemanenan dilakukan dengan metode flokulan kimia menggunakan NaOH. Kendala yang terdapat dalam teknik kultur Chlorella sp. adalah media kultur yang tidak bebas dari kontaminan, kepadatan awal yang tidak optimal, dan kondisi lingkungan yang tidak baik. Kondisi lingkungan yang tidak baik seperti kualitas air yang tidak sesuai dengan habitat Chlorella sp. dan kondisi cuaca yang fluktuatif akibat musim pancaroba yang mempengaruhi intensitas cahaya pada kultur Chlorella sp. skala intermediet.

AbstrakTeknologi akuaponik merupakan teknologi kombinasi akuakultur dan hidroponik yang bertujuan untuk memelihara ikan dan tanaman dalam satu sistem yang saling terhubung (Sibarani, 2013). Limbah yang dihasilkan oleh ikan seperti feses dan pakan, digunakan sebagai pupuk untuk tanaman. Kemudian air yang dialirkan dari media pemeliharaan dibersihkan olah tanaman sehingga dapat digunakan kembali oleh ikan (Wahap,2010). Menurut Rokocy (2010) interaksi antara ikan dan tanaman menghasilkan lingkungan yang ideal untuk tumbuh sehingga lebih produktif dari metode tradisional.Tujuan penelitian ini adalah untuk mengetahui pengaruh media tanam terhadap pertumbuhan belut (Monopterus albus) dalam sistem akuaponik. Penelitian ini dilakukan pada bulan Agustus sampai September 2016 di Fakultas Perikanan dan Kelautan Universitas Airlangga. Percobaan terdiri dari empat perlakuan dan lima ulangan, tanpa media tanam sebagai kontrol ( P0), media tanam zeolit (P1), media tanam batu apung (P2) dan media tanam pecahan batu bata (P3). Hasil pengamatan yang didapatkan dari penggunaan teknologi akuaponik dengan media tanam selada terbaik yang dapat mempengaruhi pertumbuhan belut yaitu media tanam zeolit. Pada pengamatan menunjukkan laju pertumbuhan spesifik dengan media tanam zeolit (1,19%/hari), kelulushidupan belut dengan media tanam zeolit (70%), Penambahan tinggi selada pada media tanam zeolit ( 11,39 cm), dan kandungan amonia terendah pada media tanam zeolit pada hari ke-28 (0,03 mg/L). AbstractAquaponics is the combination of aquaculture and hydroponic technology which aim to raise fish as well as grow the plants in an interconnected system (Sibarani, 2014). The wastes that are produced by fish such as feces and feed are used as plants fertilization. The water that is flowed from media culture will be filtered by the plants so that could be reused by fish (Wahap, 2010). According to Rokocy (2010) the interaction between fish and plants will creates an ideal environment for them to growing compared to the traditional method. The objective of this research is to find out the effect of cultivation media on the eel (Monopterus albus) growth in the aquaponics. This research was conducted at August until September 2016 at Fishery and Marine Faculty of Airlangga University. The experiments consisted of four treatments in five repetitions. The P0 was the treatment without cultivation media as control treatment, P1 was the treatment using zeolite, P2 was the treatment using pumice stone, P3 was the treatment using brickbat.Observations obtained from the use of technology aquaponics with the best lettuce planting medium that can affect the growth of eels that zeolite planting medium. In observation indicates the specific growth rate with planting medium zeolite (1.19%), survival rate of eel with planting medium zeolite (70%), high additions to the growing media lettuce zeolite (11.39 cm), and the lowest ammonia content of the growing media zeolite on the 28th day (0.03 mg /L).

Infection of Staphylococcus epidermidis is still a common problem in many hospitals. Factor determining biofilm formation makes it harder for atibiotics to cure the infection. Roselle (Hibiscus sabdariffa), a well known traditional medicine plant, is a potential candidate as a drug againts infectious disease. The purpose of this research is to investigate the antibacterial effect of ethanol extract from Roselle (Hibiscus sabdariffa) calyx againts the growth of Staphylococcus epidermidis. Assessment for antibacterial effect is performed using broth diffusion method. The extract is made by maceration of the calyx of Roselle in 96% ethanol. Extracts with concentration of 125, 62.5, 31.25, 15.63, 7.81, 3.90, 1.95, 0.97, 0.48, 0.24 125, 62.5, 31.25, 15.63, 7.81, 3.90, 1.95, 0.97, 0.48, 0.24

The using of synthetic packaging generally has a problem for healthy and nature. This plastic rubbish can’t degredable by nature and soil. Necessary alternative packaging technology which safe and degredable that is edible film. Use of single material in edible film as starch have some shortage, that is brittle and rigid. Therefore, it is necessary to add material as plasticizer. Plasticizer that use in this study is Carboxymethyl Cellulose. This purpose of this study is to know the effect addition of carboxymethyl cellulose on characterization edible film from propagules mangorve B.gymnorrhiza. The method of this study is experimental with Completely Randomized Design. The treatment is concentration addition of CMC, that is A (0%), B (0,2%), C (0,4%), D (0,6%), E (0,8%), F (1%) and G (1,2%), with four repeatations. Parameters measured were thcikness, water vapor transmission rate, tensile strength and elongation at break. Data analysis using Analysis of Varioan (ANOVA) and if there is difference significant on the result, further with Duncan’s Multiple Range Test. The result of this study show that addition of CMC have different very significant (p<0,01) on thickness, water vapor transmission rate, tensile strength and elongation at break. The best treatment in this study is treatment G (addition CMC concentration 1,2%) with scoring method which basicaly on JIS (Japanesse Industrial Standard)
