Abstract

Fermentation of whey often faces problems with the product clarity due to the milk solids residue from previous cheese making process. The aim of this research was to determine the clarity and the performance of fermented whey precipitation process in the presence of pectin and chitosan as coagulant. Whey was initially pasteurized and added with pectin and chitosan prior to fermentation with mixed starter culture. Fermented whey was stored in refrigerator for 24 hours. Data were obtained using visual analysis by 15 semi-trained panelists. Qualitative scorings were given by (+) or (-) markings from the specified criteria. The data were compiled in a table, showcasing the observed characteristics at the initial and final states of fermentation. The results showed that the highest clarity (+++) was achieved by the fermented whey with the addition of pectin, as well as most stable sediment performance (+++) was also produced by pectin treatment. However, while fermented whey with the addition of pectin exhibited clarity, the level of clarity achieved by fermented whey with the addition of chitosan was superior.

Abstract

Abstract Pectin is an industrial raw material that can form gels, thickeners, and emulsifiers widely applied in the food and non-food industries. Extracting pectin with citric acid solvent using ultrasonic waves is considered more effective and efficient. This study aimed to obtain an optimization model for the pectin production process to produce maximum pectin yield and obtain the optimized pectin characteristics. This study used the Response Surface Methodology (RSM) as the optimization method with the Central Composite Design (CCD) experimental design with Design Expert 13 software to determine the treatment combination based on time factors and solvent concentration. The treatment combination obtained was 11. The results showed that the maximum pectin yield value was 34.63% at a 7-minute extraction time using the citric acid solvent concentration of 20% and a validation value accuracy of 99.08%. The optimized pectin characteristics were a water content of 7.66%, ash content of 0.33%, equivalent weight of 183.28 mg, methoxyl content of 7.52%, galacturonic acid content of 67.13%, and degree of esterification of 63.56%. The pectin produced followed the pectin quality standards according to the International Pectin Producers Association (IPPA), except for the equivalent weight.Keywords: extraction, lemon albedo, pectin, ultrasonic AbstrakPektin merupakan bahan baku industri yang memiliki kemampuan dalam pembentukan gel, zat pengental, dan sebagai zat pengemulsi yang banyak diaplikasikan pada industri pangan dan non-pangan. Proses ekstraksi pektin dengan pelarut asam sitrat menggunakan bantuan gelombang ultrasonik dianggap lebih efektif dan efisien. Tujuan penelitian adalah untuk mendapatkan model optimasi proses produksi pektin hingga menghasilkan rendemen pektin yang maksimum dan mendapatkan karakteristik pektin hasil optimasi. Metode optimasi dalam penelitian ini menggunakan Response Surface Methodology (RSM) dengan dengan rancangan eksperimen Central Composite Design (CCD) menggunakan software Design Expert 13 untuk menentukan kombinasi perlakuan berdasarkan faktor waktu dan konsentrasi pelarut. Kombinasi perlakuan yang diperoleh adalah 11. Hasil penelitian menunjukkan bahwa nilai rendemen pektin maksimum adalah 34,63% pada waktu ekstraksi 7 menit dengan konsentrasi pelarut asam sitrat 20% dengan keakuratan nilai validasi adalah 99,08%. Karakteristik pektin hasil optimasi diperoleh nilai kadar air 7,66%, kadar abu 0,33%, berat ekuivalen 183,28 mg, kadar metoksil 7,52%, kadar asam galakturonat 67,13%, dan derajat esterifikasi 63,56%. Pektin yang dihasilkan sudah sesuai dengan standar mutu pektin menurut International Pectin Producers Association (IPPA) kecuali pada berat ekuivalen.Kata kunci: albedo lemon, ekstraksi, pektin, ultrasonik

Abstract

In recent times, local culture has begun to be displaced by modernisation, and environmental awareness has declined. Therefore, efforts are needed to revive love for local culture and the environment. The purpose of this study is to create artwork with themes of local culture and the environment, namely, medallion reliefs and wood waste. Artwork featuring themes of local culture and the reuse of waste is one of the efforts to introduce, preserve, and conserve local culture and the environment through art. The research method employs Arts-Based Research. The artistic practice follows a three-stage experimental sequence: the exploration stage, the design stage, and the realisation stage. The results of this research indicate that wood waste has high potential for being utilised as an alternative medium for creating artworks. The result of this creative process is an environmentally friendly and affordable collage artwork themed around a medallion. _______________________________________________________________________________   Beberapa waktu terakhir budaya lokal mulai tergeser oleh modernisasi, dan kecintaan terhadap lingkungan mengalami kemerosotan. Sehingga dibutuhkan suatu upaya untuk menumbuhkan kembali kecintaan budaya lokal dan lingkungan. Tujuan penelitian ini ialah untuk menciptakan karya seni dengan tema budaya lokal dan berbasis lingkungan yakni relief medalion dan limbah kayu. Karya seni dengan tema budaya lokal dan pemanfaatan limbah menjadi salah satu upaya untuk mengenalkan, menjaga dan melestarikan budaya lokal dan lingkungan melalui karya seni. Metode penelitian memakai Arts based Research. Praktek artistik menggunakan urutan eksperimen tiga tahap, yaitu: tahap eksplorasi, tahap perancangan, dan tahap perwujudan. Hasil dari penelitian ini menunjukan bahwa limbah kayu memiliki pontensi tinggi untuk dimanfaatkan menjadi alternatif medium penciptaan karya seni. Hasil proses kreatif ini yaitu karya seni kolase bertema medalion yang ramah lingkungan dan terjangkau.
