Abstract

Drosophila melanogaster or commonly known as the fruit fly, is a type of insect found in rotting fruits or vegetables and plants material around the world with a wide distribution. This study aims at determining the LC50 value of eggs, larvae, pupae and the reproductive potential of adult fruit flies (Drosophila melanogaster) exposed to cypermethrin. The method used was an experiment using a completely randomized design (CRD). The data of mortality from toxicity tests were analyzed by ANOVA and Probit test using the SPSS application, while data on reproductive potential parameters were analyzed using the life table method using Ms. Excel. The results of this study showed that the LC50 value of cypermethrin was different at each development stage. The LC50 value from the lowest to the highest successively starts at the egg development stage, which was 1654,824 ppm, then at the egg stage was 3067,192 ppm, the imago stage was 3155,848 ppm and the pupae stage was 3755,014 ppm. The reproductive potential and population rate of D. melanogaster decreased significantly with increasing concentration, lower than the control. The best concentration that was able to reduce the value of the net reproduction rate (R0) and the ability of the population to multiply (λ) was 266.6 ppm with an average value of 0.22 and 0.86, respectively. Further, the best concentration in reducing the average life period (T) and the population reproductive potential (rm) were a concentration of 250.0 ppm with an average value of each parameter of 9.64 and -0.03.

Abstract

The Timber Legality Verification System (SVLK) is one of the emerging government initiatives to tackle illegal logging and promote legal timber in Indonesia to International Country. The system aims to ensure that timber and wood products produced in Indonesia come from verifiable legal sources. SVLK is implemented through certification mechanism by independent party (Wood Legality Verification Institution / LVLK) which has been accredited by National Accreditation Committee. The purpose of this study is to find out how the influence of the implementation of government rules on the obligation to have SVLK against companies that export wooden furniture products in Jepara. This study will use 30 companies engaged in the export of Wood Furniture to foreign countries who entered as members of the Indonesian Furniture and Handicraft Association (HIMKI) Jepara Raya, Central Java. The results of this study will be forwarded to stakeholders related to SVLK implementation obligations in the furniture industry,whether the policy has a positive or negative impact on furniture industry exports in Jepara This research is descriptive and qualitative. Data collection methods were conducted using field research with interviews and some questioner to obtain primary and secondary data, observation, and literature.
