Abstract

The development of advanced membrane technologies is essential for addressing environmental challenges, particularly in wastewater treatment and oil-water separation. Polyvinyl alcohol (PVA) is a hydrophilic, environmentally friendly polymer commonly used for membrane fabrication; however, it suffers from high swelling and low mechanical strength, which limits its long-term performance. To overcome these drawbacks, carbon nanotubes (CNTs) were incorporated into the PVA matrix to form PVA-CNT composite membranes. CNTs serve as structural reinforcements, enhancing mechanical strength, thermal stability, and inter-chain bonding within the PVA network. The interconnected pore structure and high conductivity of CNTs also improve membrane selectivity and reduce swelling by stabilizing the polymer structure when exposed to water or aqueous solutions. Additionally, the modified surface properties provided by CNTs result in superior fouling resistance, minimizing pore blockage and maintaining water flux over extended operation periods. This study demonstrates that PVA-CNT composite membranes offer a sustainable and energy-efficient solution for separation processes, making them highly suitable for oil-water separation, industrial wastewater treatment, and other filtration applications such as water purification and organic compound removal. The findings highlight the potential of PVA-CNT membranes as a green technology that combines high performance with environmental sustainability. PVA-CNT membranes offer a promising approach for developing next-generation membranes with optimized structural and functional properties for environmental applications.

Abstract

Pemeriksaan sedimen urine merupakan pemeriksaan mikroskopis unsur-unsur organik dan anorganik dari darah, ginjal, saluran kemih yang bertujuan untuk pemeriksaan penyaring. Meskipun pemeriksaan dilakukan dengan alat analyzer urine otomatis, namun konfirmasi hasil tetap menggunakan cara manual dengan pewarna Sternheimer malbin sebagai baku emas. Urine disentrifuge sehingga unsur-unsur organik dan anorganik mengendap dan endapan tersebut diambil lalu diberi zat pewarna. Zat warna ini bersifat karsinogen, tidak stabil dan toksik bagi lingkungan sehingga perlu dicari pewarna alternatif yang alami, misalnya curcuminoid yang terdapat pada rimpang kunyit (Curcuma longaLinn). Curcumin yang berwarna kuning umum digunakan sebagai pewarna makanan, tekstil dan jaringan. Sifat curcuminoid pada kunyit yang aman, mudah larut dalam etanol, mudah meresap di dalam jaringan dan mudah ditemukan diharapkan dapat mewarnai sedimen urine dan digunakan sebagai pengganti Stenheimer Malbin dalam pewarnaan rutin sedimen urine di laboratorium. Penelitian ini bertujuan untuk mengetahui kemampuan curcumin dalam mewarnai sedimen urine yang meliputi sel epitel, sel darah, dan kristal sekaligus menentukan konsentrasi optimalnya. Penelitian ini dilakukan secara eksperimen dengan perlakuan menggunakan pewarna ekstrak curcumin 5%, 10%, 20%, 30%, 50%. Pemeriksaan sedimen urine menggunakan metode mikroskopis dengan sampel urine patologis selama satu bulan. Penilaian menggunakan likert scale 1-3 meliputi tingkat pewarnaan, kontras, dan kekotoran. Setelah dilakukan penelitian variasi konsentrasi ekstrak curcumin 10% yang optimal dalam mewarnai sedimen urine dapat dijadikan alternatif pengganti pewarna Sternheimer-malbin

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

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.

Abstract

Kandungan zat besi baik di dalam ASI maupun susu formula keduanya rendah serta bervariasi. Namun bayi yang mendapat ASI mempunyai risiko yang lebih kecil untuk mengalami kekurangan zat besi dibanding dengan bayi yang mendapat susu formula. Hal ini disebabkan karena zat besi yang berasal dari ASI lebih mudah diserap, yaitu 20-50% dibandingkan hanya 4 -7% pada susu formula. Keadaan ini tidak perlu dikuatirkan karena dengan pemberian makanan padat yang mengandung zat besi mulai usia 6 bulan masalah kekurangan zat besi ini dapat diatasi(Hendarto & Pringgadini 2013). Fe merupakan salah satu zat yang berperan dalam pertumbuhan bayi. Dan banyak yang masyarakat yang beraggapan bahwa status gizi pada ibu berpengaruh dalam komponen dalam ASI. Penelitian ini bertujuan untuk mengetahu besar kandungan Fe dalam Air susu ibu dengan metode Atomic Aborbtion Spectroscopy (AAS). Hasil penelitian di dapatkan Hb pada ibu menyusui normal Pada penelitian ini dapat disimpulkan bahwa tidak ada perbedaan yang signifikan kadar Fe dalam ASI pada ibu menyusui dengan Hb normal dengan ibu menyusui yang anemia.

Abstract

The increasing consumption of plastic, particularly single-use packaging, has led to a significant rise in household plastic waste, which poses a potential threat to environmental sustainability. One type of waste that remains underutilized is metallic plastic packaging. This Community Service activity aimed to enhance community knowledge and skills in processing metallic plastic packaging waste into handicraft products with functional value and economic potential. The activity was conducted in collaboration with the Family Welfare and Empowerment Group (PKK) of Ngringo Village, Karanganyar, involving 15 participants. The methods employed included a preliminary survey, educational outreach, hands-on practical training, and continuous mentoring. The effectiveness of the program was evaluated using pre-test and post-test assessments analyzed through the normalized gain (N-gain) method. The results demonstrated an improvement in participants’ knowledge and skills following the training, with an average N-gain value of 0.68, which falls within the moderate-to-high category. These findings indicate that the metallic plastic packaging waste processing training was effective in enhancing community capacity. Furthermore, the activity not only contributed to reducing plastic waste generation but also promoted the implementation of circular economy principles.
