Abstract

People from East Nusa Tenggara generally use Gewang midribs for walls and ceilings. However this midribs contains ingredients that can be attacked by organisms such as termites. To overcome this, preservation action is needed. Conventional preservatives commonly contain ingredients that are less environmentally friendly, expensive and not easily available. Therefore it is necessary to find a natural preservative from the flora species more suitable for people. The purpose of this study was to obtain data and information about the effect of the concentration of natural preservatives from Tuba extract on the Gewang midribs. Tuba extract was obtained through the maceration using methanol. Preservation was carried out by soaking the Gewang midribs samples in to tuba extract solution with the consentration (gr/liter) of 0 (control), 4, 9, 16, 25 and 36 for 24 hours at room temperature. The effectiveness of preservatives was done using soil termites test. The results showed that tuba extract had a very significant effect on decreasing the weight of the sample and increasing the quality class of gewang midirb from class IV to II. It is recommended that preserving gewang midribs can use tuba extract with a concentration at least of 4 gr per liter of water

Abstract

Ekosistem mangrove memiliki fungsi dan manfaat yang sangat penting. Namun demikian, degradasi mangrove terus meningkat karena aktivitas manusia yang berlebihan. Pemanfaatan buah mangrove merupakan salah satu cara alternatif untuk mengubah pemanfaatan yang merusak menjadi lebih ramah lingkungan. Dalam pemanfaatan buah mangrove, kandungan non gizi adalah sesuatu yang perlu diketahui. Penelitian ini bertujuan untuk mengetahui kandungan anti-nutrisi dari tannin dan kontaminan logam berat Sonneratia spp dan tepung buah Rhizophora mucronata, serta kontaminasi HCN dan mikroba tepung buah Sonneratia spp. Analisis dilakukan di laboratorium terkait di Bogor. Hasil penelitian menunjukkan bahwa kandungan Sonneratia spp tannin adalah 0,26% dan R. mucronata adalah 0,12-0,26%. Isi Pb, Mn, Cu, Hg dan As (dalam mg / kg) tepung Sonneratia spp adalah 0,28; 10.13; 13.3; <0,005; dan <0,003; sedangkan R. mucronata adalah 1,18-4,24; 14.99-20.31; 3,65-5,23; <0,005; dan <0,005. Kandungan HCN Sonneratia spp adalah <3 mg / kg, jumlah lempeng <10 koloni / gram, Escherichia coli <3APM / gram, Bacillus cereus 0 koloni / gram, Salmonella sp negatif, cetakan <10 koloni / gram dan ragi <10 koloni / gram. Hasil-hasil itu menunjukkan bahwa kandungan tanin dari kedua jenis tepung itu lebih rendah daripada beberapa spesies mangrove lain dalam studi serupa dan relatif aman dikonsumsi karena di bawah SNI dan persyaratan Acceptable Daily Intake.
