Abstract

The potensi of sea weeds farming development in Indonesia is very big, because of large suitable locations, high sea weeds variety, simple technology and small capital relatively. But now this effort facing serious problem that caused by ice-ice disease. That disease usually happen when rainy (October-April) and catching becaused bacterium and the effect of more old the sea weeds and less nutrition. Ice-ice was signed by red pocks then yellow, white and then moults. The change environment suddenly such us salinity, temperature and light intensity were main factor that triggers ice-ice. Pseudoalteromonas gracillis, Pseudomonas spp. and Vibrio spp can isolated from sea weeds that attackted. Remember that disease is so harm, so need to do efforts to solve that problem. One of sollution is do the right and consistent of standard operating procedure (SOP) in sea weeds farming. This SOP consist of three stages, choose suitable locations, qualified sea weed seeds and use sitable technology. Wish the lost of economic will be minimal with applying this SOP.

Abstract

Alat tangkap garuk yang ada di daerah Tambak Lorok Semarang terdiri dari 3 jenis garuk, yaitu garuk biasa, garuk modifikasi dengan rantai dan garuk modifikasi dengan timbal. Adanya modifikasi alat tangkap garuk ini disebabkan oleh karena kurang efektifnya penangkapan udang jika menggunakan penggaruk, karena untuk penangkapan udang sebenarnya cukup dengan desain yang berfungsi untuk mengaduk permukaan substrat dasar perairan sehingga udang akan meloncat untuk masuk dalam cakupan alat tangkap. Penelitian ini bertujuan untuk menganalisis hasil tangkapan udang putih (Penaeus merguiensis) dari 3 jenis garuk udang dan menganalisis perbandingan kelayakan usaha dari 3 jenis alat tangkap garuk udang. Metode penelitian yang digunakan adalah metode deskriptif studi kasus. Pengambilan sampel  hasil tangkapan udang dilakukan pada 3 jenis alat tangkap Garuk Udang selama 3 bulan dengan setiap bulannya diambil data 10 hari. Pengumpulan data dilakukan dengan observasi langsung dan wawancara terhadap nelayan. Analisis teknis dengan membandingkan antara garuk udang biasa dengan garuk udang modifikasi rantai. Sedangkan analisis kelayakan usaha membandingkan antara garuk udang biasa dengan garuk udang modifikasi rantai dengan menggunakan undiscounted criteria yaitu R/C Ratio, Payback Period, Break Event Point. Hasil penelitian menunjukkan bahwa diantara 3 jenis alat tangkap garuk udang yang ada di Tambak Lorok Semarang, Garuk Udang Modifikasi Timah merupakan alat tangkap yang terbaik, dengan hasil tangkapan udang selama 30 hari sebesar 194,64 kg. Berdasarkan analisa usahanya alat tangkap garuk udang biasa mempunyai nilai R/C 1.45, PP 4.67 tahun, BEP produksi 191.75 kg dan BEP harga Rp. 53,683,-/kg. Alat tangkap garuk udang modifikasi rantai mempunyai nilai R/C 1.74, PP 2.89 tahun, BEP produksi 192.50 kg dan BEP harga Rp. 29,358,-/kg.  Sedangkan Alat tangkap garuk udang modifikasi timah mempunyai nilai R/C 1.91, PP 2.37 tahun, BEP produksi 192.63 kg dan BEP harga Rp. 25,549,-/kg.

Abstract

Lele dumbo merupakan salah satu komoditas penting perikanan budidaya di Indonesia. Perkembangan pengolahan ikan sekarang lebih variatif seperti pengolahan menjadi dendeng. Penambahan asap cair pada proses pembuatan dendeng dapat meningkatkan keawetan dendeng serta memberikan karakteristik sensori. Tujuan penelitian ini adalah untuk mengetahui pengaruh penambahan konsentrasi asap cair yang berbeda terhadap kualitas dendeng. Rancangan percobaan yang digunakan adalah RAL (Rancangan Acak Lengkap). Perlakuan meliputi penambahan asap cair 0% sebagai kontrol, 1%, 3%, dan 5%. Parameter uji yang diamati adalah profil asam amino, kadar air, kadar protein, kadar fenol serta uji hedonik (kenampakan, bau, rasa, dan tekstur). Hasil penelitian menunjukkan bahwa dendeng dengan penambahan asap cair tetap memiliki asam amino yang lengkap. Lisin dan leusin dominan pada asam amino esensial dengan nilai 39702,77 - 51736,24 mg/kg, serta pada asam amino non esensial asam glutamat mendominasi dengan nilai 59915,6 - 64478,57 mg/kg. Perbedaan konsentrasi asap cair pada dendeng giling ikan lele dumbo memberikan pengaruh yang nyata terhadap penurunan kadar air, kenaikan protein dan fenol serta hedonik dendeng. Semakin besar konsentrasi yang digunakan, dendeng tidak diterima oleh panelis (p < 0,05). Catfish is one of nutritionally important aquaculture species in Indonesia. Nowadays, the development of its processed method becomes more various such as the production of jerked meat. Addition of liquid smoke could increase shelf life of catfish and give sensory characteristics. This study aimed to determine the effect addition liquid smoke with different concentration on quality characteristics of jerked meat. The research method used Completely Randomized Design (CRD) with four treatments such as addition of 0% liquid smoke as control, 1%, 3%, and 5%. Parameters test observed are amino acid profiles, moisture content, protein content, and phenol content also hedonic test. Jerked meat processed with liquid smoke still have a complete amino acid . Lysine and leucine dominated on essential amino acid with range 39702,77 – 51736,24 mg/kg, while glutamic acid dominated on non essential amino acid with range 59915,6 – 64478,57 mg/kg. Meanwhile, addition of liquid smoke gave a significantly different to the moisture content, protein content, phenol content also appearance, odor, flavor, and texture of catfish jerked meat (p < 0,05).

Abstract

Teluk Awur Beach Jepara is one of the waters in Central Java that has a seagrass ecosystem. Seagrass role is the ability to support the life of another biota closely related to the fertility of the waters indicated by the content of chlorophyll-a, nitrate, and phosphate. The purpose of this study is to know the relationship between chlorophyll-a, nitrate, and phosphate to seagrass land cover as well as the variables which have major contributions. The method of study used is descriptive with four station sampling and  seagrass with a line transect of 50 m, and a 1x1 m² transect Quadrant divided into 16 sub plots measuring 25 x 25 cm² a spatial approach and multiple regression statistics. The results showed that there was a positive correlation between seagrass land cover to the concentration of chlorophyll-a and nitrate but less correlated phosphate. The highest chlorophyll-a concentrations of 0.381 mg/m3, seagrass land cover 40-60%, seagrass density 314 individual/m2, nitrate 1.141 mg/l and phosphate 0.54 mg/l. The lowest chlorophyll-a concentration ranges from 0.32-0.35 mg/m3, seagrass cover of 0-10%, seagrass density 3-12 individual/m2, nitrate 0.96 mg/l and phosphate 0, 21mg/L. This research shows that there is a strong link between seagrass land cover Concentrations of chlorophyll-a, nitrates and less influential to phosphates.
