Abstract

Penggunaan larvasida sintesis sangat merugikan masyarakat, seperti pencemaran lingkungan dan menyebabkan resistensi. Alternatif untuk mengurangi dampak negatif tersebut adalah dengan menggunakan larvasida nabati yang berasal dari tanaman yaitu serai. Tujuan dari penelitian ini adalah untuk mengetahui untuk mengetahui perbedaan jumlah kematian larva Aedes aegypti setelah pemberian abate dibandingkan pemberian serbuk serai. Jenis penelitian ini adalah eksperimen yang dilakukan pada tahun 2011, menggunakan rancangan penelitian post test only with control group design. Dengan populasi seluruh larva Aedes aegypti instar III dan IV yang berada di B2P2VRP Salatiga. Sampel berjumlah 400 ekor larva. Analisis data yang dilakukan secara univariat dan bivariat (menggunakan uji independent t-test dengan α= 0,05). Kesimpulan dari penelitian ini adalah ada perbedaan yang signifikan jumlah kematian larva Aedes aegypti setelah pemberian abate dibandingkan dengan pemberian serbuk serai, dapat dilihat dari hasil uji independent t-test, dimana nilai p=0,002 (p<0,05).The usage of sintesis larvacide harmed the society, such as contamination of enviroment, and resistense. Some alternatives to reduce the negative impact were use vegatation larvacide from flora such as lemongrass. The purpose of this research was to investigate the differences on the number of Aedes aegypti larvae mortality after giving abate compared with giving lemongrass powder.

Abstract

The study executed to know the effect of ATRA and Zn supplementations to periodontitis rat collagen treated with tetracycline.The experimental study with factorial design used 54 Wistar adult male rat. Periodontitis was resulted from porphyromonas gingivalis inoculation. Tetracycline 90 mg/kg and the supplementations were given for 7 days. Nine groups sample were randomly allocated. The independent variables were supplementation of ATRA 10; 5 mg/kg, Zn 2.5; 1 mg/kg, and their combinations. Dependent variable was collagen status i.e degradation and synthesis, consecutively measured by mRNA MMP-2 and mRNA P1CP, using reverse transcriptase polymerase chain reaction. Control was periodontitis group receiving tetracycline. T-test, ANOVA, Post Hoc Duncan and least significant differences (LSD) were used. High dose ATRA 10 mg/kg and Zn 2.5 mg/kg supplementations consecutivetly degraded (0.25 x of control) and increased collagen synthesis (4 x of control). High dose ATRA and Zn combined supplementation gave no effect to collagen degradation, but increased synthesis (3 x of control). The effect of high dose ATRA and Zn combined supplementation on collagen synthesis was the nearest to healthy condition.Penelitian ini bertujuan untuk mengetahui pengaruh suplementasi ATRA dan Zinc pada kolagen jaringan periodontium tikus periodontitis yang mendapat tetrasiklin. Studi eksperimental dengan desain faktorial dilakukan pada 54 tikus Wistar jantan dewasa. Periodontitis dihasilkan melalui inokulasi porphyromonas gingivalis. Tetrasiklin 90 mg/kg dan suplementasi diberikan selama 7 hari. Sembilan kelompok sampel terpilih secara alokasi acak. Variabel bebas adalah suplementasi ATRA 10; 5 mg/kg; Zn 2,5; 1 mg/kg; dan kombinasinya. Variabel tergantung adalah status kolagen meliputi degradasi dan sintesis, indikator mRNA MMP-2 dan mRNA P1CP, terukur dengan reverse transcriptase polymerizing chain reaction. Kontrol adalah kelompok periodontitis dan mendapat tetrasiklin. Analisis data menggunakan uji t, ANOVA, Post Hoc Duncan, dan LSD.  Suplementasi dosis tinggi ATRA 10 mg/kg dan Zn 2,5 mg/kg berturut-turut mendegradasi (0,25 x kontrol) dan meningkatkan sintesis kolagen (4 x kontrol). Kombinasi suplementasi dosis tinggi ATRA dan Zn tidak berefek pada degradasi kolagen, tetapi meningkatkan sintesisnya (3 x kontrol). Suplementasi kombinasi dosis tinggi ATRA dan Zn memberikan sintesis kolagen paling dekat dengan keadaan sehat.
