Abstract

Abstract. Cellulose from rice husk has been successfully synthesized. Rice husk is an abundant agricultural waste and has a high cellulose content. Bioconversion of rice husk into cellulose begins with the stages of delignification and bleaching. The resulting cellulose was characterized using FTIR and XRD. The IR spectra show a strong absorption peak at 3444.87 cm− 1 which is associated with stretching vibrations O − H (hydrogen bonds between molecules), absorption peaks at 1033.85 cm− 1 are identified as stretching C − O − C which is β bond −1,4 glycosidic from cellulose. XRD shows the particle size of cellulose which is 3.44 nm and has crystallinity of 58.73%. These results indicate that cellulose from rice husk has good characteristics.              Keywords: Rice Husk, Cellulose, FTIR, XRD

Abstract

The presence of water hyacinth in waters can be a threat to aquatic ecosystems. Its naturally fast growth and excess nutrients in the waters cause its growth to become uncontrollable. So it is necessary to handle the biomass and produce it. One thing that can be done is to turn it into organic fertilizer. The problem is, water hyacinth is a lead (Pb) hyperaccumulator plant. So that the biomass produced by water hyacinth contains a large amount of Pb. This study aims to see the effect of vermicomposting on the amount of Pb contained in water hyacinth biomass. The research began by converting water hyacinth biomass into a living medium for earthworms. Changes in Pb levels were observed before and after the earthworms were added. The results found a change with an average initial content of 2.7857 ppm to 2.0477 ppm. So from this study, it was found that the decrease in Pb levels was 26.4924% Keywords: waterhyacinth, hyperaccumulator,biomass, earthworm, vermicomposting.

Abstract

One of the efforts to minimize the impact of detergent waste pollution is by adsorption using coffee dregs and coconut dregs adsorbents. The purpose of this study was to determine the optimum mass of coffee grounds and coconut pulp as adsorbents, to compare the effectiveness of their absorption in decreasing levels of Linear Alkyl Benzene Sulfonate, and to study their adsorption isotherm models. This research was conducted in batches with variations in the mass of each adsorbent, namely 1 gram, 2 grams, 3 grams, 4 grams and 5 grams. This research was conducted in batches with variations in the mass of each adsorbent, namely 1 gram, 2 grams, 3 grams, 4 grams and 5 grams. The detergent waste samples were contacted with the adsorbent for 30 minutes and then the absorption capacity was tested using the Methylene Blue test method. The results showed that the optimum absorption of LAS content from coffee grounds and coconut pulp adsorbents occurred at a mass of 2 grams with the greatest increase in absorption efficiency index Coconut dregs adsorbent is more effective than coffee dregs because it can absorb up to 37%, while coffee dregs are only 10% with the same adsorbent mass of 5 grams. The adsorption isotherm model of the 2 types of adsorbents refers to the Langmuir equilibrium with R2 values for coffee grounds 0.8651 and coconut pulp 0.9868.

Abstract

Wuluh star fruit is a plant that is rich in benefits. The population of this plant is very abundant in the community both in the yard or as a shade plant in the yard. The population of this plant is not proportional to its utilization so that the star fruit usually falls and rots. Seeing this, a community service activity was carried out regarding the use of starfruit into dish soap, which besides being able to add to the economic value of starfruit, can also reduce environmental pollution. Wuluh star fruit (Averrhoa bilimbi L.) contains saponins, flavonoids, acetic acid, and vitamin C. Saponins have the ability to kill bacteria while flavonoids can destroy bacterial proteins by lysis method so that bacteria cannot reproduce and die. Saponins also function as a foam producer so that they can be used in the manufacture of dish soap. Keywords: Wuluh star fruit, saponin, dish soap

Abstract

The aim of the synthesis and characterization of Co(II) and Fe(III) metal ions with N-Ethylisopropyldithiocarbamate ligands is to produce dithiocarbamate complex molecules that can be utilized in pharmacology, industry, agriculture, and chemistry in the future. The in situ method, which involves reacting secondary amines with carbon disulfide in ethanol solvent (dithiocarbamate ligands) and metals dissolved in ethanol solvent (metal ions), was used to synthesize complicated chemicals. Melting point, conductivity value, FT-IR, and UV-Vis analyses were used to characterize complicated compounds. The resulting Co(II)-N-Etilisopropyldithiocarbamate complex compounds are black in color and Fe(III)-N-Ethylisopropyldithiocarbamate are dark green, with a yield of 64.12% and 41.87%, respectively, with different conductivity values,≠0 (electrolyte compound). From the results of the FT-IR analysis, the presence of Co-S bonds was identified at the absorption band of 362.62 cm-1 and Fe-S at the absorption band of 354.90 cm-1. Maximum wavelength absorption UV-Vis, Co(II) (λmax = 330 nm) > Fe(III) (λmax = 310 nm). Characterization results based on the measurement of kinematic viscosity values, Fe(III)-N-ethylisopropyldithiocarbamate complex compounds are more effective as the additives in lubricants than Co(II)-N–Ethylisopropyldithiocarbamate at a temperature of 100 oC.

Abstract

The ideal quality of lubricant can be obtained by adding additives. One of the functions of additives in lubricants is to maintain viscosity against temperature changes. Dithiocarbamate complexes with heavy metals have very low solubility in water so that dithiocarbamate compounds have great potential as additives in lubricants. This research was conducted in an effort to determine the effect of temperature (40 oC and 100 oC) on the viscosity of the lubricant and metal ions (Mn2+, Fe3+, Co2+) in the synthesis of dithiocarbamate complex compounds on their potential as additives in lubricants. This compound was synthesized by in situ method and to measure and compare the viscosity of the lubricant before and after the addition of the complex compound as an additive.The results showed that complex compounds from N-ethylisopropylditiocarbamate ligands could be synthesized with metal ions Mn(II), Fe(III) and Co(II). Where is the synthesis of complex compounds obtained yields Mn(II)-N-ethylisopropylditiocarbamate amounted to 49.59%, Fe(III)-N-Ethylisopropyldithiocarbamate of 41.81%,and Co(II)-N-Etilisopropil ditiocarbamate by64.12%.From the results of the characterization of the viscosity test, it can be seen that temperature and metal ions in complex compounds affect their potential effectiveness as additives in lubricants. Of the three complex compounds it is more effective at 100 oC than 40 oC, where metal ions Mn (II) are more effective than Fe(III) and Co (II). Keywords: Lubricants, additives, metal ions, temperature, dithiocarbamate.

Abstract

This community service program aimed to enhance the visibility and market reach of liquid organic fertilizer (biourine), a by product of cow farming, through the utilization of e-commerce platforms. The partner, a cattle farmer producing biourine, had limited skills in digital marketing. The program was implemented using the 3P approach, Preparation, Learning, and Strengthening which included socialization, training on product packaging and labeling, e-commerce-based marketing practices, financial recording using Microsoft Excel, assistance in creating an online store account, as well as evaluation and sustainability strategies. The results show that the partner successfully produced properly packaged products and established an online store that has begun to be used for sales transactions. Monitoring of the store’s performance indicated increased marketing activity and greater partner engagement in online selling processes. In addition, collaboration with the village-owned enterprise (BumDes) and the development of social media accounts further expanded the potential distribution of the product both locally and digitally. This program demonstrates that the application of e-commerce can significantly improve product visibility while strengthening the partner’s independence in managing livestock by product enterprises.
