Abstract

Teknik membran ultrafiltrasi mempunyai peran sangat penting dalam kemajuan industri pangan, misalnya dalam proses pemekatan susu kedelai dari isolat protein kedelai. Material yang dipakai dalam teknik membran ultrafiltrasi pada umumnya bersifat hidrofobik karena tahan terhadap bahan kimia, sifat mekanik yang baik dan mempunyai kestabilan termal yang baik. Pada penelitian ini telah dilakukan pembuatan, karakterisasi dan optimasi membran berdasarkan variasi prosentasi polisulfon dalam membran. Hasil yang diperoleh menunjukan bahwa melalui analisis morfologi, Struktur membran yang diperoleh berbentuk asimetrik, yang memiliki dua lapisan pori yang berbeda. Lapisan kulit yang lebih rapat dibanding sub lapisannya. Hasil uji  fluks air maupun larutan dekstran menunjukan bahwa semakin besar komposisi polimer dalam membran nilai fluksnya semakin turun. Kecenderungan sebaliknya teramati pada hasil uji permselektifitas membran. Nilai MWCO 580 kD dicapai oleh dua jenis membran dengan komposisi polimer 18% dan 20%. Dengan mempertimbangkan dua aspek utama kinerja membran yaitu fluks dan permselektifitas membran, membran dengan komposisi polimer 18% akan dipakai sebagai membran dasar untuk proses modifikasi membran pada tahap selanjutnya dengan teknik UV-fotografting.

Abstract

Zinc deficiency is one of the serious health problems experienced by half of the world population who consumes rice as a staple food. Zn biofortification of rice is aimed to increase the concentration of Zn, and its bioavailability in rice is one of a growing research. Some of the compounds used in Zn biofortification include Zn sulfate, Zn EDTA, Zn nitrate, Zn chloride, Zn organic and Zn amino acids (i.e., a combination of ZnSO4 and amino acids). Among those various compounds of zincs, Zn biofortification of rice by foliar application of solution ZnSO4 mixed with amino acid is the best in improving the concentration of Zn in polished rice and also its bio-availability. This article discusses the effect of the use of fish protein hydrolysate solution containing amino acids and peptides added with ZnSO4 for zinc biofortification of rice. Fish hydrolysate solution mixed with ZnSO4 were applied by foliar spraying on rice in three applications at intervals of 8 days, starting 73 days after planting, when the rice begins to flower. Spraying was performed in the morning, between 08:00 - 09:30 o’clock on the samples and the control plots. The results showed that the rice crop sprayed with fish hydrolysate mixed with ZnSO4 has increased the rice production by 7 % in weight and the polished rice which was sprayed with fish hydrolysate mixed with ZnSO4 contains 40 % higher of Zn (17.1 ppm) than in controls (12.0 ppm). Keywords: zinc biofortification, fish protein hydrolysate, zinc sulfates.

Abstract

SINTESIS HIDROGEL KOPOLIMER PATI ILES-ILES DENGAN ASAM AKRILAT, AKRILAMIDA DAN METILENABISA KRILAMIDA SEBAGAI PEMBENAH TANAH.Hidrogel kopolimer cangkok pati iles-iles dengan asam akrilat, akrilamida dan metilena bis-akrilamida disintesis menggunakan teknik polimerisasi dalam larutan dengan pelarut air dan inisiator kaliumpersulfat. Pati iles-iles yang digunakan diperoleh dengan menghomogenkan umbi iles-iles, mencucinya dengan air dan menggumpalkannya dengan metanol beberapa kali.Kelarutan pati iles-iles yang diperoleh dengan cara tersebutmencapai 5%b/b. Polimerisasi dalam larutan dilakukan tanpa hembusan gas nitrogen. Hidrogel yang dihasilkan ditentukan daya serap airnya dan struktur kimianya berdasarkan spektrumFTIR. Berdasarkan berat hidrogel yang dihasilkan dapat dikatakan bahwa sintesis menghasilkan 100 % polimerisasi pada suhu 55-60 °C. Hidrogel yang dihasilkan pada kondisi polimerisasi tertentu mempunyai daya serap air hingga 51 kali, yaitu yang disintesis dengan perbandingan konsentrasi pati iles-iles dengan asamakrilat, akrilamida dan bis-akrilamida = 1:3:3:0,01. Hidrogel kopolimer kemudian digunakan sebagai pembenah tanah dengan mempelajari kemampuan tanah berpasir dalammenyimpan dan menguapkan airnya. Tanah berpasir yang dicampur dengan 0,5 % b/b hidrogel dapat menyerap air hingga dua setengah kali dari pada tanah tanpa hidrogel dan dapat menahan lebih dari separo air yang diserapnya saat terjadi kesetimbangan penguapan dan penyerapan air. Kesetimbangan penguapan dan penyerapan air dicapai setelah 5 hari pada suhu udara 23-29 °C dan kelembaban 40-83 %.

Abstract

In the separation process of solution containing protein, interaction between membrane surface and protein can cause fouling irreversibely. So, efficiency of filtration process will decline. In this research, to improve the effeciency of filtration was done by modification of membrane using UV-photografting technique. Acrylic acid had been introduced topolysulphone membrane via this technique. The hydrophylic membrane was obtained. The membrane performance was evaluated in soymilk fouling test. The first step of research had obtained PSF membrane optimation about PSF 18%. In second step, the research was focused on the modification and characterization of PSF membrane by UV-Fotografting tehchnique. In this technique, monomer concentration and radiation time was used as variable. As the result, PSF membrane had been modificated succesfully by UV- photografting tehchnique with optimum condition in 15 minutes time radiation and concentration of acrylic acid 5%. Performance of modified membranes (flux and permselectivity) were better than unmodified membranes. The fouling test showed that the modified membranes have reduced fouling degree significantly. Keywords : Ultrafiltration membrane, UV-photografting, flux and permselectivity, fouling

Abstract

The aim of this study is to determine the effect of the addition of fish hydrolyzate with variuos concentration to the standard feed and feed storage duration towards the decrease of odor by observing total nitrogen content in the excreta of laying chicken. 108 laying chicken aged forty-six weeks were divided into 12 (twelve) treatment combination. Each treatment consists of 9 (nine) laying chickens. All the laying chickens were kept in a battery cage and were fed with commercial standard feed which was added with fish hydrolysate in three different concentrations (0; 1; and 2%) during the 5-day feeding treatment period. Each standard feed which was added with different concentrations of fish hydrolysate were stored for a number of different day variations (0; 5; 10; and 15 days) before being fed to the laying chickens . The variables analyzed were water content and total nitrogen content in the excreta. Results showed that the total nitrogen content in the excreta was not affected (sig> 0.05) by the duration of feed storage but was significantly affected (sig <0.05) by the addition of fish hydrolyzate with different concentration. The use of fish hydrolyzate in 1-2%  concentration reduce the levels of water content and total nitrogen content of laying chicken excreta.

Abstract

Feed management, which accounts for 70% of overall production expenses, is one of the cornerstones of effective broiler chicken farming. The body weight, health, and nitrogen levels in faeces can all be improved by adding additives to feed. This community service's goal is to guide and support broiler chicken breeders in their usage of fish hydrolyzed for feed management. This activity was carried out in August and September 2023 in the chicken farming partner owned by Mrs. Cholili's with a production capacity of up to 20,000 in Mumbulsari village, Mumbulsari district, Jember Regency. The methods are counselling, feeding practices and assistance during the production phase. The outcome is mastering the technique for adding fish hydrolyzed to enhance the health and growth performance of chickens. This skill and knowledge could be implemented by other farmers to maximize yields by using fish hydrolyzate.

Abstract

Agricultural yields can be increased through fertilization. Conventional fertilization by spreading fertilizer on agricultural land is very ineffective. As much as 40-70% of the nitrogen from urea given through conventional fertilization will be leaching. This problem can be overcome by implementing a new fertilization system, namely by applying controlled fertilizer release technology or Control Release Fertilizer (CRF). The CRF system is made by loading or mixing urea fertilizer at the time of synthesis of a composite based on Arrowroot Starch-g-poly (acrylamide-co-acrylic acid)/zeolite. Fertilizer will come off gradually during fertilizing the land. Synthesis of starch-based hydrogel composite Arrowroot Starch-g-poly (acrylamide-co-acrylic acid)/zeolite loaded or mixed with urea fertilizer, has been successfully carried out. The composite's structure characterized by IR spectroscopy and its ability as CRF has also been tested through swelling and urea release tests in distilled water, phosphate buffer pH 5, pH 7 and pH 9. The results show that the swelling capacity and urea release in distilled water > Buffer pH 7 > pH 9 > pH 5. The welling degree in distilled water, Buffer pH 5, pH 7 and pH 9 is 39.078; 18,719; 36,296 and 33,510 g.g-1 respectively and the release of urea is 2,129; 1,829; 2,110; and 2,091 mg.mL-1 respectively and they showed significant differences.

Abstract

This study aims to synthesize a hydrogel zeolite composite of arrowroot starch graft copolymerized with acrylic acid through a radical polymerization reaction in a water. Various scenarios were tested using different natural zeolite concentration to determine the impact on swelling/water absorption of the composite. The resulting product was a solid gel-the test results showed that the swelling increased as the ratio of starch to acrylic acid decreased. Increased starch concentrations generally lead to decreased water absorption (swelling capacity). Adding a zeolite improved swelling to some extent and the optimum zeolite concentration was 60%. The increased concentration of zeolite also hardened the hydrogel composite. The highest swelling in the hydrogel composite of starch-g-poly(acrylic acid)/zeolite 60% is 1056.25 g.g-1. FTIR analysis of functional groups was conducted to determine differences in the IR spectra of arrowroot starch, acrylic acid, hydrogels, zeolites, and composite hydrogel. Si-O signal appearing on the IR spectra of hydrogel composite with wave number 1030 cm-1 indicates that composite hydrogel with zeolite was synthesized
