Abstract

Penelitian ini bertujuan untuk menggambarkan batimetri perairan Pelabuhan Penyeberangan Desa Mororejo Kaliwungu Kabupaten Kendal dan selanjutnya menentukan alur pelayaran yang aman dan efisien.Penelitian ini dilaksanakan pada tanggal 24 - 27 Mei 2013 di Pelabuhan Penyeberangan Mororejo Kabupaten Kendal. Data yang digunakan adalah data primer dan data sekunder. Data primer yaitu data perekaman batimetri dengan menggunakan Echosounder Singlebeam 585, data pasang surut lapangan selama 3 hari, dan data pasang surut lapangan dari instansi Stasiun Meteorologi dan Maritim Semarang pada bulan Mei 2013. Metode penelitian yang digunakan adalah metode kuantitatif. Metode analisis data dengan metode matematis dan pendekatan pemodelan menggunakan perangkat lunak Surfer 9.0 dan Global Mapper.Hasil penelitian menunjukkan kelerengan dasar perairan kawasan Pelabuhan Penyeberangan Kabupaten kendal cenderung landai dengan nilai kelerengan rata – rata sebesar 0,321 % atau bisa dikategorikan Flat to almost flat (rata/hampir rata). Kapal yang dapat berlabuh memiliki berat maksimal 5000 GT atau setara kapal yang memiliki draft maksimal 6,5 m. Sedangkan untuk alur pelayaran memiliki 2 jalur yaitu jalur pemberangkatan dan jalur kedatangan menuju dan dari arah jalur pelayaran nasional Kumai - Semarang. Sehingga alur pelayaran yang terbentuk memiliki arah berbeda antara jalur pemberangkatan dan jalur kedatangan kapal.

Abstract

AbstrakPenelitian ini bertujuan untuk mempelajari pengaruh lama waktu pengeringan terhadap karakteristik terasi jembret instan dari produsen yang berbeda. Penelitian ini dilaksanakan di laboratorium Teknologi Hasil Perikanan, Laboratorium Kimia Jurusan Teknologi Hasil Pertanian, Laboratorium Pra Panen Jurusan Teknologi Pertanian, dan Laboratorium Bio Proses Fakultas teknik, Universitas Sriwijaya. Penelitian ini dilaksanakan pada bulan Juni sampai dengan Feberuari 2011. Metode penelitian ini menggunakan  Rancangan Acak Lengkap (RAL), Perbedaan lama waktu pengeringan (15, 30, 45,  dan 60 menit) digunakan sebagai perlakuan dan diulang sebanyak tiga kali. Parameter yang diamati pada penelitian ini meliputi analisis kimia (kadar air, abu, protein, lemak), analisa fisik (warna kelarutan, ukuran bubuk dan desistas), analisa mikrobiologi adalah jumlah total mikroba/total plate count (TPC), dan analisa sensoris dilakukan dengan menggunakan uji hedonic (aroma dan warna). Hasil penelitian menunjukkan bahwa perlakuan perbedaan lama waktu pengeringan yang dilakukan berpengaruh nyata terhadap sifat kimia (kadar air, kadar lemak, kadar protein) dan sifat fisika (ukuran butiran bubuk, kelarutan), tetapi pengaruh tidak nyata terhadap sifat kimia (kadar abu), sifat fisika (densitas) dan analisa sensoris (aroma dan warna). Hasil pengamatan pada penelitian ini menunjukkan bahwa perlakuan T4 (lama waktu pengeringan 60 menit) merupakan perlakuan terbaik. Hasil penelitian yang didapatkan yaitu dengan rata-rata kadar air (0,36%), kadar abu (35,78%), kadar lemak (1,08%), kadar protein (45,66%) dan dengan rata-rata ukuran butiran bubuk (0,28 um), kelarutan (27,33 detik), densitas (0,57 g/mL dan mikrobiologi (4,63 cfu/mL). Hasil uji hedonic yang paling disukai panelis adalah perlakuan T3 (lama waktu pengeringan 45 menit) dengan penilaian untuk warna (2,92) dan T4 (lama waktu pengeringan 60 menit) dengan penilaian untuk aroma (2,88).

Abstract

The objective of this research was to know effect of solvent (NaHCO3 0,5% and MgCO3 0,03%) and Tween 80 (0,5%, 1%, and 1,5%) to obtain the chlorophyll and phytochemical compounds of kiambang leaves. The research used factorial randomized block design with two treatments and each treatment was replicated three times. The treatments were  the type of solvent (NaHCO3 0.5% and MgCO3 0.03%) and the concentration of Tween 80 (0.5%, 1% and 1.5%). The parameters of research were total chlorophyll content, water dissolve chlorophyll, phytochemichal, colour intensity (Hunter a, Hunter b, and Lightness), and colour stability. The result showed that the average of total chlorophyll ranges from 10.261 mg/L to 16.435 mg/L, water dissolve chlorophyll ranges from 4.503 mg/L to 5.739 mg/L, Hunter a ranges from -2.8 to -4.667, Hunter b ranges from +6.1 to +14.6, Lightness ranges from 29.4 to 34.067. Phytochemical compounds of kiambang leaves were alkaloid, fenol, and saponin. The colour stability test of kiambang leaves by using NaHCO3 0.5% and Tween 80 1.5% indicated the best colour stability during four weeks storage in aerobic condition.   Keyword: kiambang extract, chlorophyll, phytochemical

Abstract

This purposes of this research were to determine the effect of different carbohydrat sources on the the characteristics of chemical, microbiological and organoleptic bekasam  catfish. The research was conducted in June until July 2011 at Fishery Processing Technology Laboratory, Aquaculture Laboratory, Animal Nutrition Laboratory and Bioprocess Laboratory University of Sriwijaya.This research that the used Completely Randomized Design (CRD) with five treatments, and each treatment was replicated three times. The treatment were  A1 = glutinous rice flour, A2 = corn flour, A3= wheat flour , A4 = cassava flour, A5 = rice flour.The result showed used of different carbohydrate sources had significant effect in N-amino content, pH value and total count but was significantly for water content and ash content. The highest bacterial count was obtained by using rice flour (4,491) and the lowest was found in bekasam with glutinous rice (3.470). The flour that has a higher amylose content is easier to use as a bacterial growth media. Based on sensory test, the best treatment was derived from rice flour and had a higher preference level aroma (3.64), tekstur (3.86) and apperance (3.27). The research recomended that bekasam that used rice flour had best physical, chemical and mikrobiology properties.

The purpose of this research was to determine the effect of addition squid ink to the quality of wet noodle. The completely randomized design was used in this research with 5 treatments and three replications. The treatment were 0%, 0,5%, 1%, 1,%% and 2% of squid ink. The parameter were chemical analysis (protein content, ash content, carbohydrate content, water content, and vitamin A), physical analysis (color and elongasi of wet noodle) and sensory test (color, aroma, texture and taste by hedonic test). The result show that the treatment was significant on color (lightness, chroma and hue), chemical analysis (protein content, carbohydrate content, and water content), hedonic (color and taste). Treatment of wet noodle A3 with combination squid ink 1,5 %, is the best treatment that liked by panel. The result of sensori evaluation with characteristic elongasi 72,67 %, lightness 35,050, hue 127,60, chroma 1,070, protein content 7,11 %, carbohydrate content 14,85 %, water content 52,57 %, and ash content 0,34 %.
