Abstract

Fucoxanthin is an anticancer, antioxidant, antimicrobial, and anti-inflammatory bioactive compound. Unfortunately, the conjugated double bonds of the fucoxanthin structure make it unstable, posing issues for product development, particularly with regard to shelf life. This research study aims to synthesize nano chitosan–pectin and encapsulate isolated fucoxanthin by nano chitosan–pectin using an ionic gelation method. Fucoxanthin was obtained through isolation of microalgae species Cyclotella striata. The best result of nanoparticle size using a particle size analyzer was chitosan:pectin 1 : 2 of 172 nm. Fourier transform infrared analysis showed that there was an interaction between chitosan–pectin and fucoxanthin, which was characterized by a shift in the C O absorption fucoxanthin from 1736 to 1632 cm-1. The result of morphological analysis of nano chitosan–pectin–fucoxanthin using a scanning electron microscopeshows a spherical morphology with a size between 140 and 265 nm. The result of encapsulation efficiency was 75.18%, whereas encapsulation stability increased fucoxanthin oxidation half-life 4.7 times longer than that of unencapsulated fucoxanthin. The nano chitosan pectin could be utilized as a matrix conjugate to increase the stability of fucoxanthin significantly by encapsulation. This information is expected to be useful in developing encapsulation applications for unstable compounds.

Abstract

In this study, the transformed zeolite from Lampung natural zeolite (LNZ) was used as a catalyst for the pyrolysis of a mixture of cassava tubers and rubber seed oil to produce bio crude oil (BCO). Transformation of Lampung natural zeolite into zeolite-A was attempted by adjusting the Si/Al ratios to 1.0, 1.5, and 2.0 transformed with and without aluminum addition and hydrothermal method with variation Si/Al ratio of 1.0; 1.5 and 2.0. The resulting products were specified as Zeo-C, Zeo-R1, Zeo-R1.5 and Zeo-R2.0. XRD analysis results show that Zeo-C and Zeo-R2 were transformed into zeolite-P, while zeolite-A, as targeted, was found in Zeo-R1 and Zeo-R1.5. SEM analysis results were also in accordance with XRD analysis results that showed the bipyramid crystal of zeolite-P in Zeo-C and Zeo-R2, while the cubic crystal of zeolite-A in Zeo-R1 and Zeo-R1.5. The BCO produced by using Zeo-C and Zeo-R1.5 as catalysts has the highest hydrocarbon content of 81% and 98%, respectively. Compared to previous studies, our study introduces an innovative approach by utilizing LNZ, a resource that has not been extensively explored, and combining cassava and rubber seed oil to produce bio-crude oil with a high hydrocarbon content. Our study contributes by promoting the use of underutilized biomass resources, potentially providing an environmentally friendly and economically viable alternative for BCO production.

Abstract

Kegiatan pengabdian ini bertujuan meningkatkan kemampuan Siswa dan Siswi SMAN 2 Kota Agung untuk mengelola sampah plastik menjadi suatu produk yang lebih bermanfaat. Selain untuk meningkatkan nilai tambah sampah plastik, upaya ini juga bertujuan untuk mengatasi masalah kebersihan lingkungan, sekaligus mendukung program pemerintah dalam zero waste program. Dalam kegiatan pengabdian ini dilakukan sosialisasi pengelolaan sampah dengan konsep Reduce, Reuse, dan Recycle (3R), dan peningkatan nilai ekonomis sampah plastik yang masih dapat dijual. Melalui kegiatan pengabdian ini mitra yang merupakan siswa dan siswi SMAN 2 Kota Agung mendapatkan pengetahuan yang bermanfaat dan memiliki kemampuan untuk memilah sampah, khususnya sampah plastik. Dengan demikian semakin banyak sampah yang dapat didaur ulang dan dimanfaatkan kembali menjadi produk lainnya. Kegiatan ini perlu dilakukan karena daur ulang sampah untuk mengurangi atau mengatasi terjadinya pencemaran lingkungan sangat membantu program pemerintah.

Abstract

This research aims to obtain biodiesel by transesterification of coconut oil with MgO/SiO2 as a catalyst, with the objective to examine the effect of MgO loads on the performance of the catalysts expressed in terms of oil conversion. The MgO/SiO2 composites with different mass ratios of 1:1, 1:2, 1:3, 1:5, and 1:10 were synthesized from Mg(NO3)·6H2O and SiO2 extracted from rice husk silica using sol-gel method and followed by calcination at 800 °C for 6 h. The produced catalysts were then tested in the transesterification of coconut oil to investigate the effect of catalyst composition, oil to methanol ratios, and reaction times. The experiments were carried out using a fixed catalyst load of 10% oil (w/v) and at 70 °C. The catalyst with the highest performance was then characterized by using X-ray diffraction (XRD) and scanning electron microscopy (SEM) to confirm the formation of crystalline MgO/SiO2. The highest conversion of the transesterification product was analyzed using gas chromatography-mass spectrometry (GC-MS) technique to confirm the biodiesel production. The XRD diffractogram of the synthesized sample is characterized by the presence of sharp peaks confirming the existence of the sample as crystalline material attributed to the pyroxene-ideal (MgO3Si) phase. The existence of the sample as crystalline material is also supported by the absence of a broad diffraction peak attributed to amorphous rice husk silica, and SEM image of the sample which is characterized by the visible existence of crystalline structure in the forms of platelet prismatic, and tetrahedral shaped structures. The results demonstrated that the highest conversion (98%) was achieved with the use of MgO/SiO2 (1:5) as a catalyst, a ratio of oil to methanol of 1:6, and a reaction time of 4 h. The formation of methyl esters was confirmed by the results of GC-MS analysis.

Abstract

The management of slaughterhouse wastewater presents significant environmental challenges due to its high organic load, fat, oil, and persistent pollutants. Electrocoagulation (EC) is an effective treatment method that utilizes electric currents to generate in situ coagulants for pollutant removal. This review examines key operational parameters of EC, including current density, pH, electrode type, and contact time, while comparing its performance with electro-oxidation (EO) and coagulation-flocculation (CF). The findings indicate that EC effectively reduces Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), and turbidity with relatively low operational costs. Integrating EC with CF and EO improves treatment efficiency by addressing complex wastewater characteristics. Optimization of parameters, energy consumption reduction, and electrode durability enhancements are recommended for improving EC performance. Bibliometric analysis using VOSviewer highlights the increasing research focus on energy efficiency, electrode materials, and process optimization. A graphical abstract is provided to illustrate EC’s role in wastewater treatment, highlighting its effectiveness, optimization strategies, and integration potential. Future research should focus on scaling up industrial applications and integrating predictive models to enhance efficiency and sustainability in slaughterhouse wastewater management.
