Anthracnose disease in chillies is a serious problem for farmers. So far, synthetic fungicides have been used as solution for the treatment of this disease. However, the side effects of synthetic fungicides to public health and environment raised awareness on alternative fungicides derived from natural resources. This paper aims to review plants that are potential as an alternative to fungicides for chili plantation, fabrication of test solutions, in vitro and in vivo fungicide test. Many plants were investigated as alternatives to plant-based fungicide. The utilization of leaves as samples including rhizomes, roots, tubers, weevils, seeds, fruit, flowers and other parts of the plant. The extract fabrication method used as a fungicide test include: maceration method, gradual fractionation method, and decoction method. The maceration method is the method most widely used to extract fungicidal active compounds from plants. Some studies that carried out in vitro tests were unable to compare with synthetic fungicides so it was not possible to determine their effectiveness for plant-based fungicide for chillies when compared to synthetic fungicides. In vitro Extract of 80% alcohol and 10%/60% n-hexane of pacar cina (Aglaia odorata L.) leaves can be compared with the performance of propineb 0.2%. In addition, the 60% and 70% kirinyuh (Chromolaena odorata L.) leaf extracts were also able to match Acrobat 0.2% performance in vitro. Based on the in vivo test, suren (Toona sureni Merr) leaf extract and nut bulbs can be used as an alternative to vegetable / natural fungicides to help overcome the problem of anthracnose in chilies.

Leucas zeylanica (L.) R. Br. (L. zeylanica) originated from Lamiaceae family which is also known as “Pokok ketumbit” by local Malaysian is famous for therapeutic treatment uses especially in India and Sri Lanka. Throughout this study, four different solvents which were n-hexane, chloroform, methanol, and distilled water used in the extraction method using cold maceration technique. Optimization was done and methanol became the best solvent that produced highest percentage yield compared to the other solvents and also been chose to carry out a few other analysis. The extracts were subjected to qualitative and quantitative analyses to determine the phytochemical constituents present in aerial parts of L. zeylanica. The Fourier Transform Infrared spectroscopy – Attenuated Total Reflection (FTIR-ATR) results showed few significance peaks according to extracted solvents. Qualitative analysis on the methanolic extract showed that L. zeylanica contains phenol, flavonoid and tannin through phytochemical screening tests using colorimetric method. The Gas Chromatography – Mass Spectrometry (GC-MS) results demonstrated few fatty acids been extracted in both n-hexane and chloroform extracts with high peak area, while Liquid Chromatography Tandem with Mass Spectrometry (LC-MS-MS) results identified that chloroform extract showed fragment spectrum of tricin [M+H]+ ion at m/z 328.1 with retention time of 19.49 min, while methanol extract had two fragment spectrum of tricin and apigenin at m/z 282.3 and 270.4 in positive ion mode at 19.53 min and 16.70 min respectively. Quantitative analysis on methanolic extract was done via Ultra Violet-visible spectrophotometric assay for estimation of total phenolic content (TPC), total flavonoid content (TFC) and total tannin content (TTC). TPC showed a gallic acid standard calibration curve, y = 0.0063x + 0.02 and estimated amount was 151.54 ± 0.04 mg of gallic acid equivalent/ 1 g of extract, meanwhile TFC displayed a quercetin standard calibration curve of y = 0.0050x + 0.037 and estimated amount of flavonoids was 71.76 ± 0.2 mg of quercetin equivalent/ 1 g of extract. Additionally, The toxicity test for the L. zeylanica extract showing that this compound is safe and non-toxic in term of skin irritation, cytotoxicity and also genotoxicity.

Morphological characterization of gram-positive and gram-negative bacteria from treated latex processing wastewater Farrah Aini Dahalan; Nor Azizah Parmin

Publisher : Universitas Nahdlatul Ulama Surabaya

A preliminary morphological screening and isolation of bacterial colony from latex industrial wastewater was carried out. Bacteria colonies from latex processing wastewater were isolated from a local latex processing industry. It was found that 17 bacterial isolates had been purified grown on nutrient agar under 35˚C. The colonies were then purified and morphologically indicated via Gram staining and motility test. After morphological observation, it was identified that out of 17 isolates, 9 isolates were Gram positive and 8 isolates were Gram negative. There are 11 out of 17 colonies were rod-shaped bacterial colonies, while the other 6 colonies were cocci-shaped bacteria. There were 11 colonies of gliding bacteria, three colonies were non-motile bacteria and the other three colonies were flagellated bacteria. This study is only limited to morphological observation as the main aim of this study was to investigate the potential occurrence of viable growth in treated latex processing wastewater. The bacterial colonies were classified base on their morphological properties shown. This study has classified several genera such as Staphylococcus, Escherichia, Thiobacillus, Arthrobacter and other Genus. The growth curve of 17 isolates studied and the chemical oxygen demand were determined.

Appropriate technology adaptation to mitigate community transmission of SARS CoV2 virus in resourced challenged Bhutan and Bangladesh Nadim Reza Khandaker

The SARS CoV2 pandemic has a tremendous impact on both developed and developing countries. To mitigate against community transmission of SARS CoV2 in Southern Bhutan and Central Bangladesh, the development and application of appropriate technologies was undertaken. As an appropriate mitigation, hand washing station was constructed by a simple system. The system was operated using a foot pedal to limit cross contamination by direct hand contact, hand sanitizer utilization and disinfection application in Central Bangladesh. The study highlighted a local innovation in constrained environments to provide public health solutions for preventing the spread of SARS CoV2. The innovation and mitigation measures can be replicated in other resource challenged regions of the world as mitigations steps to limit community transmission of SARS CoV2.

Removal of silver nanoparticles using phytoremediation method Aida Atikah Mad Akahir; Zainab Mat Lazim; Salmiati Salmiati

Publisher : Universitas Nahdlatul Ulama Surabaya

This paper presents on removal of silver nanoparticles using phytoremediation. In this study, floating macrophyte (Pistia stratiotes) was used for phytoremediation of silver nanoparticles. This study investigated the performance of Pistia stratiotes in the removal of silver nanoparticles using phytoremediation method. The silver nanoparticles were green synthesized by using Muntingia calabura sp. leaves as reducing and stabilizing agent. The silver nanoparticles were successful synthesized as a peak appeared at wavelength 450 nm by UV-Vis spectrophotometer, while Pistia stratiotes had been acclimatized in tank at laboratory. Similar size of Pistia stratiotes had been employed for investigation. Each selected Pistia stratiotes was placed in 5 L bottles water containing different concentration (0.5 ppm, 1.0 ppm, 2.0 ppm and 3.0 ppm) of silver nanoparticles. This study was evaluated using UV-Vis spectrophotometer for five days. The results showed that the highest removal was achieved 69.88% at concentration of 0.5 ppm. This percentage removal relatively decreased up to 55.61% as concentration increase at 3.0 ppm. These results prescribed that phytoremediation of silver nanoparticles by Pistia stratiotes can be considered to apply and implement in water environment for AgNPs removal.

Publisher : Universitas Nahdlatul Ulama Surabaya

There are several environmental issues caused by economic growth and urbanization, such as soil degradation, water scarcity, deforestation, and biodiversity extinction. To solve these environmental problem issues, cleaner production (CP) had presented as account to reduce waste generation, energy usage and environmental pollution.CP concept was accepted and applied on many industrial sectors. Based on the current trend, CP is shifting to tackle global environmental problems by focusing on reducing carbon emission and resources consumption. In this paper, implementation of CP was presented such as waste and pollutants reduction, process and products efficiency improvements, and risk reduction towards human and environment. Overall, CP is an effective tool not only in environmental protection, but also in company management as it can increase the profit gains, reduce resources consumption, reduce pollutants emission and protects the safety of staff and workers.
