Abstract

Catfish nursery pond water generally contains ammonia and nitrites. Ammonia and nitrite in this fish farming system start with uneaten catfish feed residue, feces, and metabolic products that enter the waters. Utilization of catfish feed which contains high protein can absorbed by fish as much as 20-30% of nutrients. The rest will be excreted in the form of feces. Feces and food scraps that settle in this water contain ammonia and nitrites, which affect the quality of the water. Efforts to maintain water quality are by reducing and disposing of pond water in the river. This is categorized as water pollution. Efforts to control this water pollution are the technique of bioremediation. The aim of bioremediation techniques is to restore the ecological balance in waters by utilizing microorganisms so that a process of degradation of harmful and complex compounds occurs into harmless compounds. The microorganisms used in this study were bacteria Rhodopseudomonas palustris which can to oxidize and decompose organic matter effectively reducing water quality. This research was conducted to examine the effect of bacterial efficiency Rhodopseudomonas palustris as a bioremediator for catfish pond water waste based on reducing levels of ammonia and nitrite. Testing the ammonia and nitrite levels using a spectrophotometric method with different wavelengths. Observations in this test were carried out for three days under anaerobic conditions and light at a temperature of 33°C. Observations showed that bacteria Rhodopseudomonas palustris had an effect on reducing nitrite levels 12.65% greater than the control. While the addition of bacteria to the observation of ammonia levels did not have a decreasing effect as indicated by the value F <F crit.

Abstract

PT. Indo Acidatama Tbk. is a company that produces ethanol. Ethanol is produced by fermentation using molasses derived from sugar processing waste. To get the optimal ethanol content, it can be determined from the yield produced, it is necessary to have effectiveness in the fermentation process. In this experiment, the fermentation process was carried out with variations in molasses concentration and pH. The aim was to determine the combination of brix concentration and molasses pH in producing the most effective ethanol yield. The concentration of molasses used was 16 obrix, 20 obrix and 24 obrix. While the pH used was 4, 5 and 6. In the determination of the ethanol content, the separation was carried out by a distillation process, then the distilled ethanol was tested using a spindle alcoholmeter and a chromatographic test was carried out using a Gas Chromatography type 6890N. After getting the ethanol content, the next step is to determine the yield by using the alcohol content calculation. The results of the chromatography test obtained samples of 24 obrix variations and pH 4, getting the highest concentration, which was 3.05%. From the calculation of alcohol content, the sample variation of 16 obrix and pH 5 got the highest yield value, with an average of 26.74. From the results of the Two-Way ANOVA calculation, it was found that obrix and pH had a significant effect on ethanol yield.

Abstract

The Merdeka Curriculum has been implemented in the Education unit. The Merdeka Curriculum consists of intracurricular activities and projects to strengthen the profile of Pancasila students. The project to strengthen the profile of Pancasila students is a supporter of intracurricular activities in the independent curriculum. This community service aims to increase the understanding of teachers and students at SDN Sumber 1 regarding the Design of Strengthening the Pancasila Student Profile Project. This activity was carried out in 3 stages, namely the preparation, implementation and monitoring evaluation stages. The results of this activity are increasing student motivation, innovation and creativity, packaged in activities involving the use of plastic straws to make crafts and training in making hand washing soap as assistance in designing a project to strengthen the profile of Pancasila students which is going well. Participants seemed enthusiastic in taking part in activities which were expected to bring innovation and creativity in making a potential product. Activity participants also carried out the practice of the project to strengthen the profile of Pancasila students independently according to what had been trained so that it could be said that the understanding of teachers and students related to the project to strengthen the profile of Pancasila students increased. One form of P5 activity for students can be the use of plastic straw waste into crafts.  Plastic straws are a raw material that is very commonly used in various products, such as food and drink packaging. However, the use of plastic straws can also be an environmental problem if they are not processed properly. Another form of P5 activity for SDN Sumber 1 Surakarta schools can be making hand washing soap. The importance of using soap that is safe to use needs to be applied to schools.

Abstract

Teknologi membran termasuk kedalam clean technology yang sedang dikembangkan saat ini. Membran kitosan dapat diaplikasikan untuk pengolahan limbah industri tekstil. Kombinasi kitosan dengan PVA bertujuan untuk meningkatkan sifat mekanik membran yang dapat dikaji berdasarkan sifat daya serap air dan daya hantar ion membran. Ikatan polimer membran kitosan/PVA tidak terbentuk dengan baik sehingga membuat PVA larut dalam NaOH pada proses pelepasan membran dari cetakan kaca. Sintesis membran dilakukan dengan melarutkan kitosan/PVA dengan variasi komposisi kitosan/PVA (m/m) diantaranya 1:3; 1:1; 3:1. Hasil penelitian menunjukkan analisis water uptake, swelling degree, dan IEC memiliki kecenderungan semakin tinggi dengan adanya peningkatan kadar kitosan dan penurunan kadar PVA. Analisis water uptake dan swelling degree tertinggi dicapai pada komposisi kitosan/PVA 3:1 dengan nilai 9,5% dan 0,36%. Analisis IEC tertinggi dicapai pada nilai 1,25 meq pada komposisi kitosan/PVA 3:1.

Abstract

This research investigates the effectiveness of papaya leaf extract (Carica papaya L.) as a bioinsecticide against stable flies (Stomoxys calcitrans) and aims to identify the most effective concentration and solvent for killing these pests. Conducted using a Completely Randomized Design (CRD), the study utilized papaya leaf extracts obtained through maceration at concentrations of 10%, 15%, and 20%, with 96% ethanol and aquades as solvents. Phytochemical analysis confirmed the presence of beneficial compounds such as alkaloids, flavonoids, and saponins. The one-way ANOVA results revealed a significant impact of the ethanol-based extract on fly mortality, with a p-value of 0.00, while aquades showed no significant effect (p = 0.065). Notably, a 20% concentration of the ethanol extract achieved 100% mortality of stable flies within 50 minutes, indicating that papaya leaf extract is a cost-effective and environmentally friendly bioinsecticide, particularly when using ethanol as a solvent.

Abstract

The process of extracting active compounds from Moringa leaves requires efficient techniques so that active compounds can be isolated in high concentrations without damaging the chemical structure. The tool commonly used is a rotary evaporator. This research analyzes the percentage of solvent evaporation using a Rotavap Extractor and a conventional rotary evaporator. Both tools aim to maximize solvent evaporation by retaining active compounds from the extract. This research compares the effectiveness of the two tools based on the percentage of solvent evaporated and the viscosity of Moringa leaf extract with different time variations (40, 60, 80 minutes). The percentage of solvent that evaporates has an important role in determining the concentration and viscosity of Moringa leaf extract. As more solvent evaporates, the extract becomes more concentrated, increasing the viscosity due to the high concentration of active compounds. The percentage of solvent evaporated and viscosity show the same trend between the conventional rotary evaporator and the rotavap extractor, this indicates that both devices work with similar efficiency in evaporating solvent from Moringa leaf extract.
