Abstract

Forest betel plant is a plant belonging to the Piperaceae tribe. Sap of plants are often used by people as a cure boils and leaves as toxicity to mosquito larvae o f Aedes aegypti L. Was tested for BSLT (Brine shrimp Lethality Test) and antioxidants in ethanol and water ext ract of the twigs of the plant betel leaves this forest, the concentration used in the test BSLT 10 , 100 and 1000 pp m and antio xidant tests with obstacle (inhibit ion)% 5, 10, 25, 50 and 100pp m. Principles used in to xicity tests of ethanol and water extracts of p lant twigs forest betel Piper aduncum .L ( family :p iperaceae) BSLT (Brine shrimp Lethality Test) determined by the method of total mortality of larvae shrimp Artemia salina Leach extract co mpounds due to the influence of natural materials with a part icular concentration and antioxidant principle is based on the color of the solution changes DPPH (1,1-di fenil-2-pikrilhidrasil) from purple to yellow due to the presence of antio xidant compounds. Where the results of research in BSLT test showed that the LC 50 value twigs of 33.88 pp m ethanol extract and water extract of 323.593 ppm. The antio xidant test IC 50 values obtained at 140.732 pp m ethanol extract and water ext ract of 438.687 pp m with a b lank absorbance by 0.813.

Abstract

Keterbatasan sumber daya air bersih yang dihadapi oleh masyarakat sekitar tambang menjadi dilema tersendiri, kondisi ini membuat masyarakat mengunakan air void sebagai sumber air baku untuk kebutuhan sehari-hari. Pembukaan lapisan tanah dalam proses penambangan telah membuat mineral di dalam tanah terbuka. Hal ini akan menyebabkanterjadi oksidasi mineral sulfida (pirit-FeS2) yang membawa kandungan-kandungan logam berat berbahaya, seperti timah hitam (Pb), seng(Zn), arsen (As). Kondisi ini diduga akan menimbulkan gangguan kesehatan,jika dikonsumsi masyarakat. Berdasarkan hasil studi pendahuluan yang dilakukan di Pondok pesantren Darul Fatta Loa Buah, Kota Samarinda menunjukkan bahwa air bekas void batu bara sudah dimamfaatkan sejak tahun 2019 sampai dengan saat ini. Tujuan dari penelitian ini untuk mengevaluasi kesesuaiaan kualitas air dari lubang bekas tambang batu bara dan mengidentifikasi keluhan kesehatan santri serta upaya yang dilakukan untuk mengelola air kolam pasca tambang sehingga memenuhi sayarat air bersih. Metode penelitian yang dilakukan mengunakan teknik penelitian observasional deskriptif dengan desain penelitian Cross Sectional dan pengumpulan sampel mengunakan metode total sampling yang berjumlah 98 santri. Berdasarkan hasil uji didapatkan tiga parameter yang tidak memenuhi standar yaitu kekeruhan, pH dan COD, dengan status kesehatan santri 60,2 % mengalami keluhan ringan , 33,7 % mengalami keluhan sedang dan 6,1 % mengalami keluhan berat dan untuk upaya pengelolaan air dengan menambahkan kaporitKata Kunci : Parameter Air, Status Kesehatan

Abstract

Isolation and determination of optimum amylase work condition has been conducted from Bogor taro (Colocasia esculenta (L.) shoot). The aim of this research is to understand the optimum work condition and specific activity of amylase from Bogor taro. Amylase was isolated using homogenization techniques and sentrifugation. The raw extract of enzyme that contain amylase produced by Bogor taro then used to determine the total protein concentration and tested its activity in pH condition, temperature and maximum substrate concentration in various ways. The determination of total protein concentration was done with Bradford method, while the optimum work condition and specifik activity of amylase was done with dinitrosalycylic acid (DNS) method. The result of this reseach show the total protein concentration in Bogor taro is 7,88 μg/mL. Optimum work condition in Bogor taro is on acidity level (pH) 6, 600C temperature and 6 mg/mL substrate concentration. Specific activity from Bogor taro is 9573,68 U/mL. Keywords: amylase, taro tuber Bogor (Colocasia esculenta (L.) shoot), specific activity of amylase.

Abstract

Research on the validation of As determination methods on wellbore water by using atomic absorption spectrophotometer at PT. Geoservices Balikpapan has been calculated. The validation method used is APHA-3114 C, with research stages such as linearity, detection limit, quantitative limit, accuracy, precision. The results showed that the linearity test had good result with R2 ≥ 0.9997. The detection limit value was 0,000038 µg/Land the quantization limit value was 0,00129 µg/L. The %KV value obtained is smaller than the 2/3 KVHorwitz value, indicating that this method has a good precision. The determination of As in drilled well water samples is 0.9167 µg/L, then below the standard threshold of clean water quality quality based on Permenkes. 416/Menkes/PER/IX/1990. Based on the results of the research, APHA-3114 B/C method can be used to determine As in drilled well water samples. Keywords: Validation method, arsenic, wellbore water, APHA-3114B/C, AAS-VHGA.
