Abstract

Ongkea cortex, the wood bark of Mezzettia Parviflora Becc, is a traditional medicine originated from Southeastern Sulawesi (Indonesia). It has been empirically known to have antitumor property. In this study, we examined the antiproliferative activity and obtained the antimitotic compound of ongkea cortex. Antimitotic activity was ultimately determined by the inhibition of cleavage-stage of newly fertilized sea urchin (Lytechinus variegatus) eggs. A bioassay-guided fractination was performed in order to find the bioactive substance of ongkea cortex. The IC50 values of methanolic extract, ethyl acetate-soluble part of metanolic extract and ethil acetat insoluble part of metanolic extract were 1221.68 µg/mL, 2.69 µg/mL, and 15.15 µg/mL, respectively. Ethyl acetate-soluble part of metanolic extract was further investigated. It was partitionated using vacuum liquid column chromatoghraphy with different solvent system by increasing their polarities. There were three different fractions obtained. Fraction III exerted the highest inhibition activity with IC50 value of 1.33 µg/mL. It was separated subsequently to result four groups of compounds. III-C group presented the most potent inhibition activity with IC50 value of 0.7147 µg/mL. It was then subjected to preparative TLC and yieldedsix groups of subfractions. III-C-3 subfraction was indicated as the most potent compound with IC50 value of 0.3378 µg/mL. It was ten times weaker compared with antimitotic activity of Vincristine with IC50 of 0.0351 µg/mL. As a conclusian, ongkea cortex might have antimitotic property with the highest rate inhibition activity exhibited by III-C-3 compound.

Abstract

Increasing the population impact on increasing energy demand. On the other hand, the energy generation industry has been blamed as one of the contributors of carbon dioxide about 25% of total CO2 emissions worldwide. Meanwhile, the production of biogas, which aims to address the increasing need of energy, produces carbon dioxide in the range of 25–50% by volume. To overcome this, a cheap method, optimum and efficient as well as environmentally friendly in reducing CO2 levels by using Spirulina platensis is needed. This research aims to created a mathematical models and found the optimum flow rate to reduced levels of CO2 by using Spirulina platensis. This study used a glass tubular bioreactor (D = 2.6 cm) at a temperature of 30°C and irradiated with a fluorescent lamp Philips TL 36 Watt, color temperature: 6,200K cool daylight, light output: 2,600 lm, 72 lm/W. Tubular reactor was placed in a box lined with silver foil walls on three sides. With mathematical models of tubular reactor, the reaction rate constants could be predicted. Based on calculations of data and graphs, optimum volumetric velocity could also be predicted. Variation of flowrate to observed the reduction rate of CO2 was 0.25 mL/sec, 0.35 mL/sec, 0.5 mL/sec, 0.75 mL/sec, 1 mL/sec. Carbon source was 99.99% CO2.Observations of Spirulina growth was made on the flow rate of 0.25 mL/sec at the initial levels of dry weight 2.1208 g/L. The results of this study indicated that the low flowratewas a more effective way to reduced carbon dioxide levels using Spirulina platensis (= 2.82×10-4 sec-1). The highest conversion was obtained at a volumetric flow rate of 0.25 mL/sec and optimum speeds in the range of 0.3 to 0.4 mL/sec. The rate of incoming CO2 flux should be less than 0.047 mL/cm2.detik. Specific Growth Rate (µ) of Spirulina platensis in this study was 2.56×10-2 minute-1. Keywords: Spirulina platensis, a vertical tubular bioreactor, CO2 reduction ABSTRAK Meningkatnya jumlah penduduk berdampak pada peningkatan kebutuhan energi. Di lain pihak, industri pembangkit energi dituding sebagai salah satu penyumbang karbon dioksida sekitar 25% dari total emisi CO2 di seluruh dunia. Disisi lain, produksi biogas yang bertujuan untuk mengatasi peningkatan kebutuhan energi justru menghasilkan karbon dioksida pada kisaran 25 – 50% volume. Untuk mengatasi hal ini, diperlukan metode yang murah, optimum dan efisien serta ramah lingkungan dalam mengurangi kadar CO2 dengan menggunakan spirulina platensis. Penelitian ini bertujuan membuat model matematik dan menemukan kecepatan aliran yang optimum untuk menurunkan kadar CO2 dengan menggunakan Spirulina Platensis. Penelitian ini menggunakan reaktor tubularterbuat dari kaca (D = 2,6 cm) pada suhu 30°C dan disinari dengan lampu TL Philips fluoresen 36 Watt, temperatur warna: 6.200K cool daylight, light output: 2.600 lm, 72 lm/W. Reaktor tubular ditempatkan dalam kotak yang dilapisi dinding dengan kertas perak pada ketiga sisinya. Dengan model matematik reaktor tubular, dapat diprediksi konstanta kecepatan reaksinya. Berdasarkan grafik hasil perhitungan data, kecepatan volumetrik optimumnya juga dapat diprediksi. Variasi flowrate yaitu 0,25 mL/detik, 0,35 mL/detik, 0,5 mL/detik, 0,75 mL/detik, 1 mL/detik. Sumber karbon adalah CO2 99,99%. Pengamatan pertumbuhan Spirulina dilakukan pada flow rate 0,25 mL/detik dengan kadar berat kering mula – mula 2,1208 g/L. Hasil penelitian ini menunjukkan bahwa aliran lambat (flowrate rendah) merupakan cara yang lebih efektif dalam mengurangi karbon dioksida menggunakan spirulina platensis (= 2,82×10-4 detik-1). Nilai konversi tertinggi diperoleh pada kecepatan aliran volumetrik 0,25 mL/detik dan kecepatan optimumnya pada kisaran 0,3 – 0,4 mL/detik. Laju flux CO2 masuk sebaiknya kurang dari 0,047 mL/cm2.detik. Nilai Specific Growth Rate (µ) Spirulina Platensis dalam penelitian ini yaitu 2,56×10-2 menit-1.

Abstract

Aspergillus niger is a mold that can infect respiratory tract in certain condition. Azoles are used to solve this infection. Drug development on antifungal drugs still continued, one of the resorce is from plant. A plant that widely studied as antifungi is singawalang (Petiveria alliacea L.). Activity of ethanol extract and fraction of singawalang roots on Aspergillus niger tested by microdilution broth method appropriate to Clinical and Laboratory Standard Institute (CLSI) standard. Microdilution test results showed that Singawalang roots extract has antifungal activity against Aspergillus niger with Minimum Inhibition Concentration (MIC) 32 μg/mL and Minimum Fungicidal Concentration (MFC) 1048 μg/mL. Fraction that has high activity against Aspergillus niger was ethylacetate fraction of Singawalang roots with MIC 128 µg/ml dan MFC 512 μg/mL.
