Abstract

One of the problems in developing Nyawai plants is the attack of snail pests Achatina fulica (Ferussac, 1821) at seedling level of the plants. Plant damage caused by these pests is quite large and causes seedling death. One of the control efforts that can be done is utilizing biomaterials which have molluscicidal properties (can kill mollusks). This study aimed to determine the toxicity of some extracts of biomaterial to control Achatina fulica (Ferussac, 1821) pests. The research was conducted on a laboratory scale. The study used a factorial random design with 3 replications. The treatment consisted of four biomaterials namely sembung (Blumea balsamifera), gadung (Discorea hispida), tuba (Derris eliptica and betel nut (Areca catechu) with each concentration of 10.25.50 g/l. Each concentration used 4 snails as a test sample. The parameters observed were snail mortality, and Lethal Concentration (LC50 and LC95). The results showed that the gadung tuber extract had the highest toxicity as indicated by mortality of 75 % and the lowest LC95 value of 80.63 g/l. While the lowest toxicity is betel nut with mortality of 49.75 % and the highest LC95 value is 567.75 g/l. The Toxicity of tuba, pinang, and sembung are highest on 50 g/l concentration, excepted the gadung extract. In gadung extract, the highest toxicity was obtained on 10 g/l concentration. However, the application was consideration to the attack intensity of Achatina fulica (Ferussac, 1821) because the toxicity effect of biomaterial pesticide was slower than chemical molluscicide.Keywords: Achatina fulica (Ferussac, 1821), biomaterial, concentration, toxicity

Abstract

ABSTRAK Gaharu (Aquilaria microcarpa Baill.) merupakan salah satu hasil hutan yang memiliki aktivitas antioksidan. Ekstrak etanol daun A. microcarpa terbukti memiliki aktivitas antioksidan yang tergolong sangat aktif. Ekstrak etanol daun A. microcarpa kemudian dibuat menjadi sediaan suspensi dengan variasi CMC-Na sebagai agen pengsuspensi. Penelitian ini bertujuan untuk menentukan pengaruh konsentrasi CMC-Na terhadap karakteristik fisik suspensi ekstrak etanol daun A.microcarpa. Suspensi dibuat dengan variasi CMC-Na pada F1 (0,5% CMC-Na), F2 (1% CMC-Na) dan F3 (1,5% CMC-Na). Evaluasi sediaan suspensi meliputi organoleptis, uji viskositas, uji pH, uji homogenitas serta uji berat jenis suspensi. Nilai evaluasi suspensi dianalisis secara statistik dengan software SPSS 21. Hasil evaluasi fisik menunjukkan bahwa penambahan  konsentrasi CMC-Na akan meningkatkan nilai viskositas dan berat jenis sediaan. Kesimpulan dari pengujian ini adalah variasi konsentrasi CMC-Na mempengaruhi hasil viskositas, serta berat jenis suspensi (p<0,05) dan tidak mempengaruhi hasil organoleptis, homogenitas dan pH suspensi.  Kata kunci: Gaharu, suspensi, CMC-Na  ABSTRACT Gaharu (Aquilaria microcarpa Baill.) is one of the Borneo’s forest products that has antioxidant activity. Ethanol extract of A. microcarpa folium has been shown to have antioxidant activity that is classified as very active. The ethanol extract of A. microcarpa folium was then made into a suspension preparation with variations of sodium CMC as a suspending agent. This study aimed to determine the effect of sodium CMC concentration on the physical characteristics of the ethanol extract of A.microcarpa folium. Suspension was made with variations of sodium CMC in F1 (0.5% sodium CMC), F2 (1% sodium CMC) and F3 (1.5% sodium CMC). Evaluation of suspension preparations included organoleptic, viscosity test, pH test, homogeneity test and suspension specific gravity test. The suspension evaluation data were analyzed statistically with SPSS 21 Software.  The physical evaluation results showed that the addition of sodium CMC concentration would increase the viscosity and specific gravity of the preparation. The conclusion of this test was that variations in the concentration of sodium CMC affected the results of viscosity and suspension specific gravity (p <0.05) and did not affect the organoleptic yield, homogeneity and pH of the suspension. Keywords: Gaharu, suspension,
