Abstract

Drosophila melanogaster atau sering disebut juga dengan lalat buah, merupakan jenis serangga yang ditemukan pada buah atau sayuran yang membusuk dan bahan tanaman di seluruh dunia dengan distribusi yang luas. Penelitian ini bertujuan untuk menentukan nilai LC50 dari telur, larva, pupa dan serta potensi reproduksi lalat buah dewasa (Drosophila melanogaster) yang terdedah oleh sipermetrin. Metode yang digunakan adalah eksperimen dengan menggunakan Rancangan Acak Lengkap (RAL). Data kematian lalat dari uji toksisitas dianalisis dengan ANAVA serta uji Probit menggunakan aplikasi SPSS, sedangkan data parameter potensi reproduksi dianalisis dengan metode life table menggunakan Ms. Excel. Hasil penelitian ini menunjukkan bahwa Nilai LC50 sipermetrin berbeda pada setiap tahap perkembangan. Nilai LC50 dari paling rendah hingga paling tinggi berturut-turut adalah dimulai pada tahap perkembangan telur yaitu sebesar 1654,824 ppm, selanjutnya pada tahap telur sebesar 3067,192 ppm, tahap imago sebesar 3155,848 ppm dan tahap pupa sebesar 3755,014 ppm. Potensi reproduksi dan laju populasi D. melanogaster mengalami penurunan yang signifikan seiring peningkatan konsentrasi, lebih rendah dibandingkan pada kontrol. Konsentrasi terbaik yang mampu menurunkan nilai laju reproduksi bersih (R0) dan kemampuan populasi memperbanyak diri (λ) adalah 266,6 ppm dengan rata-rata nilai masing masing parameter sebesar 0,22 dan 0,86. Selanjutnya konsentrasi terbaik dalam menurunkan periode hidup rata-rata (T) dan potensi reproduksi populasi (rm) adalah konsentrasi 250,0 ppm dengan rata-rata nilai masing-masing parameter sebesar 9,64 dan -0,03. Kata Kunci: Sipermetrin, Drosophila melanogaster, lalat buah, life table, potensi reproduksi

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.

Abstract

Nature inherently provides essential resources for human sustenance. Consequently, natural resources and environmental services are increasingly utilized. However, escalating population growth and rising income levels have led to a decline in the value and quality of these resources. Uncontrolled exploitation, environmental neglect, and inadequate structured recording pose significant threats to the sustainability of natural capital at the local community level. This study investigates the potential for implementing environmental accounting practices in Umbele Village to facilitate the preparation of sustainable natural capital accounts, utilizing primary data gathered through interviews and field observations. The findings reveal that the majority of Umbele's inhabitants heavily rely on natural resources, which are increasingly affected by environmental degradation and climate change. Current governmental interventions to address these challenges are perceived as insufficient, compounded by a lack of corporate responsibility.
