Abstract

The Banana (Musa spp) was a fruit whose rate of ripening increased after harvest. The respiration rate was an indicator of the fruit’s shelf life. This cause banana to have a short shelf life and become easily damaged, necessitating the technology to reduce the ripening rate of fruit, such as coating it with biofilm. This research seeks to establish the optimal ethylene concentration on the composite chitosan PVA produced by evaporation of a colloidal chitosan solution with CNC. The produced solution was then applied to the surface of the banana using the immersion method, and seven-day changes in weight loss, color change, sugar content, and ethylene gas production were detected. Post-harvest management of bananas tries to preserve the fruit’s freshness and shelf life. The research is done to improve the shelf life of bananas by composite biofilm. The data result shows that from all variants, the composite biofilm contains chitosan, PVA, 10% glycerol, Citric acid, and 5% CNC, which is indicated to have the potential to increase the shelf life of banana fruit. Because they prevent respiration and the water evaporation processes in bananas, these properties allow banana fruits to stay fresh longer.

Abstract

Pondok pesantren (ponpes) merupakan lembaga pendidikan Islam tertua di Indonesia yang dijadikan sebagai tempat anak-anak untuk menimba ilmu pengetahuan agama. Banten dikenal sebagai salah satu provinsi yang memiliki jumlah ponpes terbanyak di Indonesia, salah satunya adalah Pondok Pesantren An-Nur yang berada di Banten, tepatnya di Kampung Jaha, Desa Pager Agung, Kecamatan Walantaka, Serang. Pondok pesantren An-Nur merupakan salah satu ponpes yatim dan dhuafa yang didirikan pada tahun 2012 diatas lahan seluas 950 m2. Saat ini pondok pesantren masih menjadi salah satu tempat yang sangat rentan terjadinya berbagai penyakit menular, salah satunya adalah penyakit kulit jenis scabies. Penyakit kulit jenis scabies paling sering ditemukan di pondok pesantren. Scabies dapat menular dengan mudah kepada para santri melalui kebiasaan menggaruk bagian tubuh yang terkena scabies, memakai pakaian secara bergantian, menggunakan alat mandi secara bersamaan, dan kebiasaan tidur yang saling berhimpit-himpitan dengan santri lainnya. Mengacu pada analisis situasi, maka dibutuh­kan upaya pencegahan serta melakukan penanganan awal terhadap penyakit ini dengan cara melaksanakan pola hidup bersih dan sehat (PHBS), serta melakukan pengobatan penyakit scabies salah satunya dengan meng­gunakan sabun belerang. Pembuatan sabun belerang ini sangat mengun­tungkan untuk dikembangkan di pondok pesantren, karena dapat dimanfaat­kan oleh para santri dalam meningkatkan keterampilan serta mewujudkan kehidupan yang bersih dan sehat dan terhindar dari penyakit kulit scabies. Dari hasil pengabdian yang telah dilakukan dapat terlihat adanya peningkatan pengetahuan dan pembiasaan pola hidup bersih dan sehat dari para santri, selain itu juga penggunaan produk sabun belerang secara rutin yang dibuat oleh para santri dapat mengurangi penyakit kulit scabies yang diderita pada santri mengalami penurunan sebesar 15.99% dan pada santriwati juga mengalami penurunan sebesar 10.64%.

Abstract

The increasing number of vehicles in Indonesia has increased air pollution and fuel consumption. The fuels commonly used come from fossil, the availability of which is limited. One solution that can be applied is switching to alternative energy, such as biodiesel from vegetable oils, including used cooking oil. This study investigates the effect of reactant ratio, catalyst weight, UV exposure, and catalyst reusability on biodiesel yield and characteristics (density and viscosity) according to Indonesian national standards (SNI). The method used involves the impregnation of CaO catalysts with TiO2 photocatalysts and simultaneous transesterification-esterification reaction for biodiesel production, with oil to methanol molar ratios of 1:6, 1:9, and 1:12 and catalyst weights of 3, 5, and 7%. The results showed that the best product had a yield of 90.6%, a density of 882 kg/m³, and a viscosity of 2.45 mm2/s at a reactant ratio of 1:9 and a catalyst weight of 5%, with UV exposure for 4 hours at a temperature of 65°C. XRD and EDS analysis revealed the presence of CaO-TiO2 compounds in the synthesized photocatalyst, and the GCMS analysis shows that FAME (fatty acid methyl ester) content in the biodiesel is more than 96%.

Abstract

The objectives of the study were to characterize natural zeolites from Cikalong, Tasikmalaya, Indonesia, and test for ammonium removal. Characterization was performed by using X-ray fluorescence (XRF), X-ray diffraction (XRD), and Scanning Electron Microscope (SEM). According to XRF analysis, the ratio of Si/Al was 6.8. The XRD pattern revealed that the zeolites were mordenite dominant phase. The SEM images showed the needles shape of mordenite typical morphology. Ammonium removal test was performed in the batch reactor with a variation on natural zeolite mass loading and adsorption time. Various isotherm models, i.e., Langmuir, Langmuir-Vageler, Freundlich, and Tempkin were fitted with the kinetic data by using optimization of the sum of the least square method. The Langmuir-Vageler model was best fitted with the error sum of squares 0.01. Furthermore, the study on kinetic models such as Lagergren’s 1st order, Pseudo 2nd order, Elovich, and Intraparticle diffusion was fitted with the ammonium adsorption isotherm data by using optimization of the sum of the least square method. The Pseudo 2nd order showed the smallest error sum of squares 0.007.

Abstract

An antibiotic-containing waste entering the water bodies is very dangerous because it can disturb the balance of the ecosystem and can modify the genetic information of natural bacteria so that resistance occurs. One type of antibiotic is ciprofloxacin (CIP) which can pollute aquatic ecosystems. One potential method that can be used to degrade the CIP is photocatalysis since it is low cost, highly effective, and environmentally friendly. To improve the performance of TiO photocatalyst, morphological engineering is carried out to form TiO nanotube arrays and then coated with natural anthocyanin sensitizer. The morphological engineering of TiO can be done through the anodization process. It is an electrochemical coating process that can convert metals to porous metal oxide layers. The effectiveness of the TiO2 photocatalyst in degrading pollutants can be increased by a dye-sensitizer addition. Commonly, natural anthocyanin dyes are chosen as sensitizers on the TiO2 semiconductor surfaces. Visible light is absorbed by the dye-sensitizer substances to speed up the electron excitation mechanism. The dye-sensitizer addition causes the TiO2 photocatalyst to be more responsive to visible light. The addition of the dye-sensitizer on the surface of TiO2 nanotubes has the potential to increase the degradation of ciprofloxacin waste using a photocatalytic process.

Abstract

One of the potential methods utilized for dye degradation is photocatalitic, due to its low cost, highly effective, and environmentally friendly. Effectivenes of TiO2 photocatalysts can be enhanced by adding a dye sensitizer. Dye-sensitizer material absorbs visible light to facilitate electron excitation process. Addition of dye-sensitizer on TiO2 photocatalyst promotes it to be more responsive to visible light. Natural anthocyanin dyes are often used as sensitizers of TiO2 semiconductors. Anthocyanins are, usually in the purple to the red color range, a group of natural dyes found in the flowers, leaves, and fruit of plants. The essential principles of dye sensitization to TiO2 have been explored in this review. It is feasible to reduce the band gap energy in the TiO2 photocatalyst by modifying it using a natural dye sensitized modification. Dye sensitizers on TiO2 nanotubes plate have the potential to be employed in a dye degradation photocatalytic system

Abstract

Synthetic dyes waste from textile industries, produce of the problematic pollutants in wastewater. TiO2 based photocatalysis are materials that exhibit excellent absorption behavior for organic compounds in wastewater due it properties including nontoxicity, high photocatalysis degradation ability, and chemical stabilities. However, several challenges exist regarding TiO2 nanotubes pure applications for dyes degradation such as poor affinity, high band gap energy, and difficulty of recovery and easy to recombination so it would decrease effectiveness of the photocatalysis process. Therefore, more design and optimization testing need to be conducted on the treatment conditions in order to reach higher removal efficiencies with lower costs. The modified physical properties by adding metal dopant, nonmetal, and sensitizer significantly enhanced photocatalysis activity. These parameters, which affect photocatalysis activity on degrade dyes waste pollutants, are discussed in the current review. As a result, the photocatalysis becomes more expected, and encourages to further research development.Keywords:TiO2, nanotubes, degradation, synthetic, dyes
