Abstract

Penelitian ini bertujuan untuk menentuan aktivitas spesifik 14C karang modern dari Kepulauan Spermonde, Sulawesi Selatan dengan metode Liquid Scintillation Counting (LSC). Pengambilan sampel karang Goniastrea favulus dilakukan di Pulau Ballang Caddi dan Pulau Lamputang wilayah middle inner zone Kepulauan Spermonde, Sulawesi Selatan. Penelitian ini melalui tiga tahapan, yakni: pencucian sampel karang, ekstraksi karbonat, dan pengukuran aktivitas 14C menggunakan LSC Hidex 300 SL. Hasil penelitian menunjukkan bahwa aktivitas spesifik rata-rata 14C dari karang Goniastrea favulus adalah 15,31 ± 0,6 dpm/g. Nilai aktivitas 14C karang modern di laut dan karang mati di daratan tidak berbeda signifikan.

Abstract

This atudy aims to compare the effect of Aedes aegypti mosquito repellent formulations from laundry wastewater combined with various concentrations of lemongrass extract (Cymbopogon nardus L) as an Aedes aegypti mosquito repellent and to prove the effectiveness of mosquito repellent through lethal concentration (LC50) and lethal time (LT50). This study uses an experimental method with a complete randomized plan (RAL) in January-May 2021 at the Laboratory of the Environmental Service, Takalar district and Lab. ILK Entomology Dept. Biology of Hasanuddin University. Formulation of Aedes aegypti mosquito repellent is sample F1 (6:2), F2 (6:1), F3 (6:1.5), F4 (6:0.5) between laundry wastewater and lemongrass extract with an observation time of 8 hours. This study used 300 Aedes aegypti mosquitoes for 3 replications with concentrations of lemongrass extract (8%, 17.5%, 20% and 25%). The ANOVA results showed a significance of P (0.014) < (0.05) which means that the Aedes aegypti mosquito repellent formulation from laundry wastewater combined with various concentrations of lemongrass extract had a very significant effect and the result of the probit analysis found that the value LC50 was 15.04% and an LT50 was 9, 87 minutes. So it can be concluded that the laundry waste combined with various concentrations of lemongrass extract has different effects on the mortality of Aedes aegypti with a level of poison that is quite toxic to the Aedes aegypti mosquito.

Abstract

Penelitian ini bertujuan untuk mengetahui kualitas madu hutan desa Terasa berdasarkan karakteristik fisika-kimia dan kandungan mineral. Karakteristik fisika-kimia seperti kadar air, kadar abu, daya hantar listrik, keasaman, pH dilakukan. Hasil menunjukkan bahwa kadar air, kadar abu, daya hantar listrik, keasaman dan pH dari madu Terasa berturut - turut adalah 22,7%, 0,59%, 0,592mS/cm, 28,026 meq/kg dan 4,85.Kata kunci : madu Terasa, karakteristik fisika-kimia This Research aimed to investigate the quality of the honey from the Terasa Village based on the physico-chemical characteristics and the mineral content. Physico-chemical characterization, such as the water level, ash level, electrical conductivity, acidity, pH was carried out. Result showedthat the water level, the ash level, the electrical conductivity, acidity and the pH were were 22.7%, 0,59%, 0.592 mS/cm, 28.026 meq/kg and 4.85,respectivelyKeywords: Terasa Village honey, physic-chemical characteristics
