Abstract

Tujuan penelitian ini untuk mengetahui pengaruh Cu terhadap komponen minyak akar wangi yang ditanam pada media tanah yang mengandung Cu. Tanaman akar wangi ditanam pada media yang mengandung 200, 800 dan 3200 mg/kg.  selama 5 bulan. Kemudian karakterisasi minyak akar wangi dari bagian akar melalui proses hidrodestilasi, analisis komposisi minyak atsiri menggunakan paduan kromatografi gas dan spektroskopi massa (KG-SM). Hasil penelitian menunjukan bahwa tanaman akar wangi dapat tumbuh di media tanah yang mengandung logam Cu artifisial dengan konsentrasi 200 dan 800 mg/kg, tetapi tidak dapat hidup pada konsentrasi 3200 mg/kg. Rendemen minyak akar wangi yang ditanam pada media tanam Cu 200 dan 800 mg/kg mengalami peningkatan jika dibandingkan dengan yang ditanam pada media tanam kontrol, sebesar 0,46 dan 0,25 %. Kandungan minyak akar wangi yang ditanam di media tanah tercemar Cu artifisal mengalami penaikan untuk senyawa-senyawa seskuiterpen yang teroksigenasi seperti veridiflorol dan spathulenol, tetapi untuk senyawa-senyawa seskuiterpen hidrokarbon seperti aromadendren mengalami penurunan. Kata kunci : Akar wangi, Minyak atsiri, dan Tembaga

Abstract

Purpose: This study aims to develop an integrated solution for real-time environmental monitoring in Riau Province, Indonesia, where air and water quality are increasingly impacted by industrial, agricultural, and climatic factors. Existing monitoring systems are often limited by their lack of real-time capabilities and predictive analytics. Methods: To address this, we designed the Water and Air Quality Monitoring System (WAQMS), which integrates sensor-based data acquisition with the Autoregressive Integrated Moving Average (ARIMA) model for forecasting. Sensor units were deployed across three pilot locations—Kampar, Siak, and Pekanbaru—to continuously collect environmental data. The ARIMA model was applied to historical datasets to predict future trends in air and water quality, while a web-based dashboard was developed to visualize real-time data and forecasts. Result: Calibration results showed a system accuracy of 85%, surpassing the national threshold of 75% set by the Indonesian Ministry of Environment and Forestry. This validates the use of WAQMS for Air Pollution Standard Index (ISPU) classification. Novelty: The novelty of this study lies in the seamless integration of AQMS and WQMS within a unified predictive monitoring system, combined with a user-friendly interface for stakeholders. The results demonstrate the system's potential as a decision-support tool for local governments, offering timely insights and enabling more effective and sustainable environmental management.
