Abstract

The amount of energy needed for daily needs causes fossil energy sources to decrease, so that efforts to develop other energy sources continue to be carried out. Biomass that has undergone further processing can be a renewable energy source. Gasification is one of the processes of processing biomass into a source of energy in the form of gas, but during this process there will be a lot of tar content produced. The amount of tar content needs to be adjusted to the standard tar content in the produced gas. The purpose of this study was to determine, analyze, and understand the effect of adding a wet scrubber to the tar content produced with rice husks as biomass. The provision of water discharge variations of 1.5 lpm, 2 lpm, and 2.5 lpm, as well as the position of the nozzle which is varied in its placement into horizontal, vertical, and collaboration, aims to determine the discharge and compatible nozzle position on the gasifier, which is seen from the tar content. contained in producer gas. The results of this gasification research will be compared with the gasifier without the addition of a wet scrubber.

Abstract

This study aims to develop an AmineQDs bioconjugation technique to enhance specific cancer cell targeting. AmineQDs were synthesized using a solvothermal method, modified with amine groups, and conjugated with folic acid via 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide- N-hydroxysuccinimide(EDC-NHS) carbodiimide activation. This bioconjugation process aims to improve the selectivity of QDs toward cancer cells, enabling more effective detection and therapy. Characterization results indicated successful bioconjugation, but the fluorescence of QDs was quenched after conjugation, likely due to electronic structure changes or self-quenching. Further evaluation of reaction conditions, including pH and buffer types, is needed to maintain optical stability. With proper optimization, AmineQDs have the potential to serve as highly accurate and efficient nanotechnology-based cancer diagnostic and therapeutic agents.

Abstract

One of the alternatives and renewable energy that is being developed is ethanol.Ethanol is better known as Gasohol. Molasses can make Gasohol through thesynthesis of molasses fermentation using a yeast starter. This study aims toanalyze how the effect of the addition of baker's yeast, the length of fermentationincubation time on the resulting alcohol content. In addition, the yield obtainedfrom the highest amount of ethanol production in the molasses fermentationprocess. Ethanol production through fermentation synthesis using the help ofmicroorganisms Saccharomyces cerevisiae. Based on the objective review, thevariation used is the amount of baker's yeast, namely 0.1; 0.2; 0.3; 0.4; and 0.5%glucose levels. The fermentation times were 24, 48, 72, 96, and 120 hours (T =30?C and pH = 5). Based on these variations, the highest alcohol productionwas 11%, obtained by adding 0.2% of yeast to the glucose content in the solution.The incubation time is 72 hours. The yield obtained for the highest alcoholcontent is 4.48%

Abstract

Industri penyamakan kulit menghasilkan limbah cair, limbah padat, dan gas. Ketiga limbah tersebut limbah cair merupakan limbah yang paling banyak dihasilkan salah satunya limbah logam berat Kromium (Cr). Oleh sebab itu perlu dilakukan pengolahan limbah terlebih dahulu sebelum dibuang ke badan air. Tujuan penelitian ini ntuk mengurangi logam berat dalam limbah cair dapat menggunakan metode adsorpsi, karena lebih ekonimis dan efisien. Daun kelor mempunyai senyawa gugus fungsi yang mendukung dalam adsorpsi sehingga dimanfaatkan sebagai biosorben. Dalam penelitian ini digunakan metode adsorpsi menggunakan biosorben daun kelor teraktivasi H2SO4 untuk menyerap logam berat kromium (Cr). Proses adsorpsi menggunakan variabel konsentrasi aktivasi asam sulfat, variabel massa terhadap sampel sebesar 0,8; 1,6 ; 2,4 ; 3,2 dan 4 %, serta variabel waktu kontak selama 60, 90, 120, 150, dan 180 menit. Hasil terbaik persen removal konsentrasi aktivasi asam sulfat 0,5 N sebesar 83,90% . Hasil terbaik memiliki presen removal pada waktu 120 menit  dengan massa 1,6 % dengan persen removal sebesar 85,81%.Kata Kunci : Adsorpsi, Biosorben, Daun Kelor, Limbah Penyamakan Kulit, Removal

Abstract

One of the industries that need attention is the woven sarong industry. This industry produces liquid waste resulting from the coloring process. Indiscriminate disposal of waste will have a detrimental impact on the environment. Therefore, it is necessary to treat the waste first. The purpose of this study was to reduce the levels of COD and TSS in the colored liquid waste of the weaving sarong industry. This research uses the adsorption method using the adsorbent Zeolite activated by sulfuric acid. The concentration of sulfuric acid used was 2.5 N. The lowest COD removal percentage with a zeolite mass of 1 gram with a time of 60 minutes was 30.98% and the highest percent COD removal with a zeolite mass of 5 grams with a time of 180 minutes was 59.61% . The lowest percentage of TSS removal with a zeolite mass of 1 gram with a time of 60 minutes was 74.16% and the highest percentage of TSS removal with a zeolite mass of 5 grams with a time of 180 minutes was 94.05%.

Abstract

Refined sugar is sugar that is produced from raw sugar through a refined processto remove impurities and molasses attached to Raw sugar. The process that will beused in the manufacture of refined sugar from raw sugar with carbonationpurification is divided into seven stages, namely: affination process, clarificationprocess, filtration process, decolorization process, evaporation process,crystallization process, drying process.
