UJI KANDUNGAN LOGAM BERAT TIMBAL (Pb) PADA KANGKUNG AIR (Ipomea aqutica F) DI KAMPUS UNPATTI POKA

Background: Kale is a vegetable that is widely consumed by the public and this vegetable is a good source of vitamin A which is very good. Complex regional Pattimura University in Ambon many people grow vegetables, among which are vegetable kale. Many around the farm population in fear that this vegetable has been exposed to metallic lead (Pb) the purpose of this study is to determine the metal content of lead (Pb). Methods: Sampling of water spinach (Ipomea aquatica F) done at two stations that have been determined, which covers parts of stems, young leaves and old leaves. Parameters taken from the water sample as the growth of plant water spinach (Ipomea aquatica F.) is a heavy metal content using Vogel quantitative method. Results: Determination of the content of Pb were analyzed using Atomic Absorption Spectrophotometer (AAS). The results showed the average content at the first station for young leaves, 0.283 ppm, old leaves, 0.200 ppm, rods, 0.283 ppm, and the water is not detected and station II respectively of young leaves, 0.283 ppm, young leaves, 0.200 ppm, rod, 0.533 and water are not detected while the residue Pb safe limits allowed by the Directorate General of POM on food only 2 ppm so the heavy metals in water spinach is still feasible for consumption. Conclusion: Based on the results of research conducted, it can be concluded that the heavy metal content in the organs of the stem, the leaves of old and young leaves of kale Water plant (Ipomea aquatica F.) at stations I and II stations are significant differences which include the trunk station I , II (0, 283, 0.533 ppm), older leaves station I, II (0, 0.200, 0.283 ppm), young leaves station I, II (0, 283, 0.200 ppm) and water at station I, II undetected.

Akar Avicennia marina merupakan bagian yang pertama terpapar logam berat timbal. Akar ini menyerap dan menyebarkan keseluruh bagian tanaman. Tujuan dari penelitian ini untuk mengkaji kandungan logam berat Pb dalam akar dan daun A. marina disekitar Kawasan Perairan Industri Terboyo, Semarang. Metode yang digunakan adalah metode deskriptif dan penentuan lokasi dengan metode purposive sampling. Pengambilan sampel meliputi air, sedimen, akar, dan daun mangrove di sepanjang aliran Sungai Sringin, Sungai Babon, dan Sungai Tenggang. Analisis kandungan logam berat di air dilakukan di Laboratorium Balai Lingkungan Hidup (BLH). Analisis kandungan logam berat di sedimen, akar, daun muda dan daun tua dilakukan di Laboratorium Balai Besar Teknologi Pencegahan Pencemaran Industri (BBTPPI) dengan menggunakan Atomic Absorbtion Spectrophotometry (AAS). Kandungan logam berat dalam air <0,00-0,01 mg/L, sedimen <0,03 - 6,23 mg/kg, akar 0,20-0,31 mg/kg, daun muda 0,10-0,13 mg/kg, dan daun tua 0,10-0,15 mg/kg. Hasil penelitian dapat disimpulkan bahwa kandungan logam berat di air diatas baku mutu (KepMen LH No. 51, 2004) sebesar 0,008 mg/L sedangkan sedimen dibawah baku mutu (National Oceanic and Atmospheric Administration, 1999) sebesar 30,24 ppm. ABSTRACT : The roots of Avicennia marina was a plant that can be accumulated by heavy metals. This plant roots were first exposed to heavy metals, especially heavy metals Pb, was the root. The roots would absorb and spread in all parts of the plant This study was aimed to examine the heavy metal content of Pb in the roots and leaves of A. marina around Area of Terboyo Industrial Water, Semarang. The method used in this research was descriptive method and the location decision with purposive sampling method. The sampling included were water, sediments, roots, mangrove leaves along Sringin River, Babon River, and Tenggang River. The analysis of heavy metal content in the water was performed in the Laboratory of Environment (BLH). The analysis of heavy metal content in the sediment, the roots, young leaves and old leaves were conducted in Laboratory Technology Center Industrial Pollution Prevention (BBTPPI) using Atomic Absorption Spectrophotometry (AAS). Heavy Metal contained in water < 0,00 to 0,01 mg/L, sediment < 0,030 to 6,23 mg/kg, the roots of A. marina were 0,20 to 0,31 mg/kg, the young leaves were 0,10 to 0,13 mg/kg, and the old leaves 0,10 to 0,15 mg/kg. the result of this research can be concluded that the heavy metal content in water were high quality standard (KepMen LH No. 51, 2004) of 0,008 mg/L and in sediments below was

The purposes of this study are to investigate the types of different collectors and their most effective height of installation in the green mussels cultivation (Perna viridis L.) impacted by heavy metal pollution in mangrove and non-mangrove waters; and to determine the content of heavy metals, especially Pb, Cu, Cd, and Hg in green mussels cultivation. This research was conducted from April to September 2018 in the coastal area of Karangdempel, Losari Sub District, Brebes Regency. The method used in this research was experimental. The results showed that the growth of green mussels after 6 months period of maintenance reached 7-9 cm long, weighing 10-13 grams per head and yielded 23-30 heads per collector. The most effective mussel collector was net sacks installed at a height of 30 cm from the bottom of the water. The number of mussels per collector was more in mangrove location compared to those in the non-mangrove location, while their growth in length and weight were relatively the same. Heavy metal content in seawater and in the mussel meat are still within the permissible limits of the Indonesian National Standard, except for the Cu content in the mussel exceeding the allowable limit; but it was relatively still safe accoring to the Decree of the Director General of Drug Control and Food, Indonesian Ministry of Health, No. 03725/B/SK/1989. Pb content in sediments in both location of green mussels cultivation and the Cisanggarung River basin is still within the safe limits. The content of Cd, Cu, and Hg in sediments tends to be high. Heavy metal content both in mangrove and non-mangrove areas was not different as a result of mangrove reforestation dominated by seedlings and saplings with little influence on the quality of the water ecologically and economically.

Eichhornia crassipes is well-known as water hyacinth. Water hyacinth grows rapidly in the nutrient-rich water and high light intensity places. The uncontrollable growth of water hyacinth has caused many negative impacts to the environment. For instance, interrupted water transport and decreased population of aquatic lives. The capacity of utilising water hyacinth is slower than water hyacinth growth and water hyacinth is still considered as a threat to theecosystem. This work was focused on the study of the pharmacological activity and heavy metal content of water hyacinth in Lake Cipondoh, Tangerang. Fresh water hyacinth was pre-treated through oven-drying and milling process. After that, each part of the plant was macerated by using multiple extraction method with 96% ethanol/water and three variations of sample-to-solvent ratios (1:30, 1:50, and 1:75 w/v). The result of the experiment showed thatwater hyacinth leaves produced an extract with lowest IC 50 (55.76 ± 6.73 ppm) compared toother parts. The most optimum solvent used to achieve this result was 96% ethanol/water (1:1 v/v). In order to obtain the lowest antioxidant activity, the sample to solvent ratio used was 1:50 and the heavy metal in the extract was very low. With this result, it was concluded that there is a promising opportunity to apply the water hyacinth growing in Lake Cipondoh, Tangerang as herbal medicine ingredient. Through this utilization, the overall number of water hyacinth in Indonesia can be reduced or at the least be controlled, so that the environmental problem caused by this plant can be minimized.
