Abstract

Genotypic selection on red chili palnts resistant to anthracnose disease at m2 generation. A superior anthracnose resistant cultivar was sought to overcome the low production due to anthracnose in red chili. For the development of superior cultivars, it was necessary to select genotypes that were resistant to anthracnose. Selection effectiveness was determined by wide diversity and high reliability. The purpose of this study was to see the diversity and heritability of agronomic characters and resistance to anthracnose on chili plants, and to select genotypes that were resistant to anthracnose. This research was conducted with a design without repetition. The plant material used was the seed of the results of gamma ray mutations in generation M2. The results of this study were: the broad diversity of phenotypes found in all characters observed, while all characters of the genotype observed had broad criteria except plant height at flowering and harvest, and at seedling period. The genotype that should be planted in the next generation was genotype number 136. Genotype number 136 was very resistant to anthracnose infection.

Abstract

Currently, the university is one of the actors in the use of chemical substances for educational purposes in practicums and research. Based on the survey, it is known that the processing of laboratory waste, especially organic wastewater, is not optimal. This needs to be considered considering that generally the university is located in the residential area so that if the wastewater pollutant, it will certainly risk causing serious impacts on the community. A wastewater treatment technology using photocatalysis can process toxic organic substances into simpler and environmentally friendly substances. This research includes several stages, namely the collection of waste organic compound from practicum and research activities, sampling of laboratory waste, and testing of waste treatment and analysis of the total content of organic compounds from permangnometric titration wastewater treatments. The results showed that the TiO2 photocatalyst with a composition of 0.8% (w / v) was able to reduce the content of organic compounds in the waste sample by 96.19027% in the reaction time of 4 days.

Abstract

Photocatalysis employing Metal-Organic Framework (MOF) material may degrade Rhodamin B pollutant. MOF photocatalytic activity can be adjusted by altering the ligands, metal ions, and modulators. This research aims to synthesize glycine-modulated zirconium perylene-based metal organic framework (Zr-PTCA-Gly) for Rhodamin B photocatalytic degradation under visible light irradiation. The activated Zr-PTCA-Gly exhibits good catalytic activity to degrade Rhodamine B with a 95% degradation efficiency.

Abstract

Methylene blue pollutants can be treated by photocatalytic methods using metal oxide-based semiconductor materials and metal organic framework (MOF). These two materials are often coupled into a composite to improve their physicochemical properties and catalytic activity. This research focuses on the synthesis of composites based on Cr-PTC MOF, ZnO, and Fe3O4 by the sonochemical method. The obtained composites were characterized and tested for catalytic activity in methylene blue pollutant degradation in an aqueous system under acidic conditions (pH = 5). Our investigation shows that the Cr-PTC@Fe3O4 composite possesses the lowest band gap energy of 1.86 eV and achieves the highest photocatalytic activity in methylene blue degradation at solution pH = 5, with a percent degradation of 84.36%. The sonochemical incorporation of Fe3O4 and Cr-PTC MOF is able to fabricate materials in a short time with better photocatalytic activity in degrading methylene blue than the single materials.

Abstract

As an adsorbent material, Metal-Organic Framework (MOF) provides several advantages, such as large surface area and pore volume, as well as stability in aqueous systems both in acidic, basic, and neutral conditions. The research successfully made a metal organic framework (MOF) from chromium and perylene that was modulated by isonicotinic acid. This was done using three different methods: hydrothermal (Cr-PTC-HIna-HT), solvothermal (Cr-PTC-HIna-ST), and sonochemical (Cr-PTC-HIna-SC). The Cr-PTC-HIna-SC showed the greatest Pb2+ ion adsorption capacity. The optimum adsorption of Pb2+ ions occurred at 150 ppm Pb2+ ion concentration, pH 5, 90 minutes of contact time, and an adsorption capacity of 149.95 mg/g at 35 °C. The dominant adsorption isotherm model is the Langmuir isotherm model with R2 = 0.9867 and follows the pseudo-second-order. The selectivity test showed that Cr-PTC-HIna-SC MOF could adsorb more Cd2+ ions than Pb2+ ions, with 250 mg/g being the best amount.

Abstract

Biodiesel plays an essential role in renewable energy as an alternative fuel to tackle the challenges of global warming, environmental degradation, and alternative fossil fuels. Oleic acid can be converted into biodiesel by the esterification process, which employs heterogeneous catalysts such as metal-organic frameworks (MOF). In this study, Zr/La-BTC MOFs were used as different kinds of catalysts to change oleic acid into biodiesel. The characterization results of Zr-BTC, La-BTC, and Zr/La-BTC using FTIR and XRD show that the MOF has been successfully formed. The crystallite sizes for La-BTC, and Zr/La-BTC MOFs are 15.7407 nm and 39.0392 nm, respectively. The surface area of Zr-BTC, La-BTC, and Zr/La-BTC MOFs are 167.101 m2/g, 12.328 m2/g, and 4.764 m2/g. The morphology of Zr-BTC MOF using SEM is irregular, La-BTC is rod-shaped crystal, and Zr/La-BTC is like a knot bond with a narrow waist. The most optimal reaction was obtained at a 5% (w/w) catalyst dosage of total oleic acid and methanol (1:60 mol), 65 °C, and a reaction time of 4 hours, producing 78.11% oleic acid conversion. GC-MS analysis identified that the biodiesel contains oleic acid, palmitic acid, methyl oleate, and methyl palmitate.

Abstract

Methylene blue wastewater from the paper, clothing, and textile industries can adversely affect aquatic ecosystems if improperly treated. One method to treat methylene blue pollutants in sewage is through photocatalysis techniques using magnesium ferrite (MgFe2O4) nanoparticle-based semiconductors. The MgFe2O4 is effective for methylene blue degradation because it is stable in aqueous systems, inexpensive, and has good photocatalytic activity. This study aims to synthesize MgFe2O4 nanoparticles with pumpkin seed extract (Cucurbita moschata) as a capping agent through a hydrothermal method. Characterization results show that MgFe2O4 nanoparticles synthesized with the addition of 3 mL pumpkin seed extract have a crystal size of 3.87 nm, cubic spinel structure, average particle size of 29 nm, and band gap energy value of 1.94 eV. The MgFe2O4 nanoparticles produced optimum degradation efficiency under mercury lamp irradiation with a degradation capacity of 391.98 mg/g at pH 12.

Abstract

Chemical laboratory wastewater contains hazardous compounds such as carcinogenic, toxic, and difficult-to-degrade substances, which can have a negative impact on the environment and human health. Therefore, the wastewater needs to be treated first before being discharged into the environment through the Waste Water Treatment Plant (WWTP) system. This research aims to develop and evaluate a Programmable Logic Controller (PLC)-based automatic wastewater quality monitoring system, focusing on two main parameters, namely pH value and turbidity. The system utilizes a pH sensor (SKU: SEN0161) and a turbidity sensor (SEN0189), whose measurement results are displayed in real-time through a Human Machine Interface (HMI). The main contribution of this research is the implementation of a PLC-based automatic monitoring system integrated with environmental sensors and HMI, which has been proven to replace manual laboratory testing more efficiently. The test results showed that the pH value of the treated wastewater was 6.00, in accordance with the quality standards of Permen LHK No. 68 of 2016 (range 6-9). The turbidity value was recorded at 27 NTU, close to the threshold set by Permenkes No. 32 Year 2017, which is a maximum of 25 NTU. Although the turbidity result slightly exceeds the threshold, the system still provides accurate and fast detection. A comparison with laboratory results showed that the PLC-based system provided results that were not significantly different quantitatively but more efficient in terms of response time and continuous monitoring. The system has the potential to be widely applied in laboratory wastewater management, which requires continuous and automated monitoring.
