Abstract

The research to measure of mercury accumulated mercury at spesies Gastropods, (fresh water sanils) in Poboya stream have been conducted from March to May 2012. Snail were collected by “Hands Picking” technique at 4 station with Purpose Random that were based on population density. Snails were became to analysis Lymneae rubiginosa M that founded at station 1,2, and 3., Melanoides torulosa B and Melanoides tuberculatus L that founded at station 4. The result of mesuare of mercury accumulated showed that it’s station and kind snails spesies in station 4 were different. The high consentration found at Melanoides torulosa B in station 4 were 0,09 ppm, and then followed by Melanoides tuberculatus L. in station 4 were 0,06 ppm, Lymneae rubiginosa in station 3 and 1were 0,05 ppm, and the low consentation mercury at Lymneae rubiginosa M. in station 2 were 0,02 ppm. Key words: Gastropods, bioaccumulator, Merkury, Poboya stream

Abstract

The aim of this research was to study natural discoloration of jamuju (Podocarpus imbricatus) and kisampang (Evodia aromatica BIL..) before and after treatment again of temperature, bumidity, and beat. Discoloration prevention conducted chemically by using antiseptic containing benzalkonium klorida (formula C), kresol or asam kresilat (formula D) and methylene bistiryiocyanate (MBT as comparison) either on log that is planed or unplaned and on sawn timber. The MBT efficacy result on jamuju and kisampang sawn timber, and formula Con kisampang timber show that it can prevent blue stain with four weeks protection period. Measurement result for brightness colour of jamuju timber on the planed is about 35,22 (MBT Under the roof-45,22 (CAC) and 10,62 (C outside)-37,14 (KAC) on the unplaned. Whereas, measurement for brightness colour of kisampang timber on the planed is about 45,04 (CAC)-53,42 (K Outside) and 8,24 (MBT Outside)-46,66 (KAC) from standard value 73,5. Measurement result for total colour variation of AE kisampang timber on the planed is about 8,80 (K outside)-22,56 (K Under the roof) and 21,57 (DAC)-40,19 (C Outside) on the unplaned. Whereas AE* of jamuju timber on the planed is about 20,49 (MBT Outside)-25,65 (DAC) and 23 (CAC)-41,02 (C. Outside) on the unplaned.

Abstract

Laboratory-scale manufactured hardboard made of Saccharum Sponaneoun Grasses (SSG), Empty Oil-palm Bunches (EOPB), and andong bamboo is potentially developed. However, initial experiment shows the hardboard did not meet Japanese Industrial Standard (JIS) and International Standard Organization (ISO) for hardboard. This paper observes modification of the hardboard to satisfy the standards. Modification includes adding alkali concentration during pulp cooking and changing the additives composition. Result shows modification can enhance the hardboard quality to satisfy JIS and ISO requirements. Fiber mixture of SSG pulp and andong/betung bamboo pulp was cooked in 10.5% alkali concentration; and 12% alkali concentration for EOPB pulp. Additives composition used were tannin-resorcinol formaldehyde/TRF adhesive, alum, and activated charcoal; without wax emulsion. The mixture of SSG pulp (50%) + EOPB pulp (50%) was the most prospective for hardboard, followed by SSG pulp (100%) solely; SSG pulp (50%) + andong bamboo pulp (50%); and SSG pulp (50%) + betung bamboo pulp (50%) as the lowest prospects. The least prospective fibrous material (betung bamboo) are expectedly be improved by using more TRF adhesive, nano-size activated charcoal and cross-linking agents.

Abstract

Bunga cengkeh (Syzygium aromaticum) diketahui mengandung alkaloid, saponin, tanin, fenolik, flavonoid, triterpenoid dan glikosida. Tujuan penelitian ini adalah untuk mengetahui aktivitas antidiare ekstrak etanol Syzygium aromaticum pada mencit putih jantan. Desain penelitian yang digunakan adalah desain penelitian eksperimental. Hewan uji yang digunakan adalah mencit putih jantan (Mus musculus) galur DDY dengan umur 2–3 bulan dengan berat badan 20–30 g sebanyak 25 ekor pengelompokan secara acak dan metode induksi dengan oleum ricini. Pembuatan ekstrak dilakukan dengan cara maserasi menggunakan pelarut etanol 70%. Dosis ekstrak yang digunakan adalah 5,25 mg/21 gBB, 21 mg/21gBB dan 42 mg/21gBB dan loperamid sebagai kontrol positif. Pengujian aktivitas antidiare ekstak etanol Bunga cengkeh (Syzygium aromaticum) menggunakan metode defekasi dengan pengamatan parameter seperti awal terjadi diare, frekuensi diare, berat fases dan lama terjadi diare setiap 30 menit selama 4 jam. Aktivitas antidiare dengan metode defekasi diketahui bahwa ekstrak etanol Bunga cengkeh (Syzygium aromaticum) dosis 5,25 mg/21 gBB dan 21 mg/21 gBB tidak berbeda signifikan dengan kontrol positif sedangkan Pemberian Na CMC 1% dan dosis 5,25 mg/21 gBB berbeda signifikan dengan kontrol positif. Ekstrak etanol Bunga cengkeh (Syzygium aromaticum) yang mempunyai aktivitas antidiare pada mencit jantan (Mus musculus) dengan metode defekasi yang diinduksi dengan oleum ricini adalah dosis 21 mg/21 gBB dan 42 mg/21 gBB. Data hasil penelitian menunjukan ekstrak etanol Bunga cengkeh (Syzygium aromaticum) mempunya aktivitas sebagai antidiare pada mecit putih jantan adalah dosis 42 mg/21 gBB karena pada dosis tersebut menunjukan parameter frekuensi diare, bobot fases, waktu awal terjadinya diare dan durasi diare yang berbeda secara signifikan.
