Abstract

Formaldehida di dalam melamin dapat muncul pada peristiwa depolimerisasi, partikel-partikel formaldehida muncul sebagai monomer dan menghasilkan racun yang berbahaya bagi kesehatan. Dalam pembuatan peralatan makan melamin ini, produsen sering menambahkan formaldehida yang tidak seimbang dengan fenol sebagai bahan baku. Penelitian ini bertujuan mengetahui kandungan formaldehida pada peralatan makan melamin. Metode Spektrofotometri Sinar Tampak yang digunakan dengan standar acuan Peraturan Kepala Balai POM RI No. HK.03.1.23.07.11.6664 tahun 2011. Hasil penelitian menunjukkan bahwa peralatan makan piring oval ware mengandung kadar formaldehida 4,68%. Tingginya kadar formaldehida pada peralatan makan melamin disebabkan dalam sistem produksi melamin yang tidak terkontrol. Sedangkan 4 sampel peralatan makan melamin lainnya tidak terdeteksi kandungan formaldehida. Kata Kunci: formaldehida, melamin, peralatan makan

Abstract

Sausage spent hen meat is one of processed protein product alternatives of animal origin. The purposes of this study were to find out the best formulation of culled laying hens sausage using mixture of carrot paste and baruk sago as filler and to evaluate the physical, chemical and functional characteristics of the sausage. The research consisted of five treatments of filler using various mixtures carrot paste and baruk sago, namely: 0%, 5%, 10%, 15% and 20% of carrot paste of the total 25% filler. The results showed that the use of carrots paste in the filler significantly improved (P < 0.05) the physical characteristics that increase the value and tenderness of the sausage cooking shrinkage. The chemical characteristics, on the other hand, indicated that moisture, protein, fat and carbohydrate contents were significantly affected, whereas ash content was not. The β-carotene content of sausage increased with the increasing consentration of carrot paste in the filler mixture. Sensory analysis showed that percentage of carrot paste in filler mixture only significantly affected flavor and texture but did not significantly affect the color and aroma of sausage. The hightest average panelists score was found in P2 formulation of 10% carrot and 15% sago. The water, ash, protein, fat, carbohydrate, and β–carotene contents of the P2 formula sausage were 60.63 %, 1.82 % , 15.72 %, 12.24 %,  8.25% and 0.04 % , respectively.

Abstract The waters around Nain Island have quite a lot of biological resources. One of the resources in these waters is the halfbeak Hemiramphus lutkei. This study aims to determine the relationship between length-weight and reproduction of the halfbeak Hemiramphus lutkei. The length-weight relationship, growth patterns and condition factors. Reproduction includes sex ratio, gonadal maturity level, gonadal maturity index and fecundity. Fish sampling were taken from the catches of fishermen. The number of samples required is 200, the samples are taken twice in two months from June-July. The length-weight relationship of male was W= 0.1705L1.8204 negative allometric growth pattern and female fish W = 0.0572L2.1962 negative allometric growth pattern. The condition factor of male and female where 0.98 ± 0.06 and 1.03 ± 0.07 respectively. The sex ratio of male and female (1: 0.835). The gonad maturity level of male (immature, developing, mature, ripe and spent) was found in June and female (immature, developing, mature, ripe and spent) found in June and July. The fecundity of ranged from 923 – 3,578 eggs with an average of 1,899 ± 666.

Abstract

Research on the diversity of algae types and their abundance in Meras waters has been carried out using structured line transect sampling and quadrant placement methods. The result is a diversity of algae types with a Shannon index (H') above 1.75. This shows that the diversity of algae types is moderate where water conditions are still good enough for algae growth. This is reinforced by the results of analysis of the structure of algal cells using TEM which found the presence of Floridian starch as evidence of the photosynthesis process taking place in these waters. When algae to grow and develop will carry out the process of photosynthesis. There were 9 species of algae found spread across 3 classes, namely 3 species of Chlorophyceae, 4 species of Phaeophyceae, and 3 species of Rhodophyceae. The results of the analysis of species abundance in these waters show that the algae species Gracilaria edulis is the most abundant, namely 7.6 individuals/m2, while the relative abundance is 0.28. The results of the analysis of photosynthetic pigments in the algae Gracilaria edulis were chlorophyll a, namely 359.335 µg, chlorophyll d 47.385 µg, and 1627.75 µg of carotene pigment. This algae pigment can be used as a raw material in the food (nutrification) and pharmaceutical industries. Keywords: Diversity of algae types, pigments, and cell structure Abstrak Penelitian Keanekaragaman jenis alga dan kelimpahannya  di perairan Meras telah dilakukan  dengan metode  pengambilan sampel line transek dan peletakan kuadran secara terstruktur. Hasilnya adalah keanekaragaman jenis alga dengan index Shannon (H’) berada di atas 1,75 Hal ini menunjukkan bahwa keanekaragaman jenis alga sedang dimana kondisi perairan masih cukup baik untuk pertumbuhan alga. Hal ini diperkuat dengan hasil analisis struktur sel alga menggunakan TEM ditemukan adanya  floridean starch bukti adanya berlangsung proses fotosintesis di perairan tersebut. Dimana alga untuk tumbuh dan berkembang akan melakukan  proses fotosintesis. Spesies alga yang ditemukan sebanyak 9 spesies yang tersebar dalam 3 kelas yaitu Chlorophyceae 3 spesies, Phaeophyceae  4 spesies dan 3 spesies Rhodophyceae. Hasil analisis kelimpahan spesies di perairan tersebut  menunjukkan bahwa spesies alga Gracilaria edulis paling melimpah yaitu 7,6 individu/m2 sedangkan kelimpahan relatifnya adalah 0,28. Hasil analisis pigmen fotosintesis  pada alga Gracilaria edulis adalah klorofil a yaitu 359,335 µg,  klorofil d 47,385 µg dan 1627,75 µg pigmen karoten. Pigmen alga ini dapat dimanfaatkan sebagai bahan baku dalam industri makanan (nutrifikasi) dan farmasetika. Kata kunci : Keanekaragaman jenis alga, pigmen, dan struktur sel.
