Item Karakterisasi Shampo Antijamur Dengan Ekstrak Kulit Jeruk Nipis(2016-03-02) Hamzah, Faizah; Hamzah, Farida HanumJeruk nipis of skin extract has been proved as antifungal containing bioactive compounds such as euganol, kaemfenol, galangin dan acetoxychavicul acetate. Incorporation of jeruk nipis of skin ekstract into shampoo is a promising approach to increase added value of jeruk nipis skin extract which mostly used as spices. Besides, antifungal shampoo with jeruk nipis skin extract is safer then those with shyntetic antifungal active material. The aims of the research were to fine out (1) effectiveness of jeruk nipis shampoo in inhibiting scalp-infecting fungi. (2) effect of addition of jeruk nipis skin ekstract on the characteristics of shampoo, and (3) preferences of jeruk nipis shampoo. Experiment were conducted by incorporating jeruk nipis skin extract into added at four different concentration (0,5%, 1%, 2% and 3%). Shampoo without jeruk nipis skin extract was used as a control. Research was perfurmed using single factor completely ramdomized design with four levels of jeruk nipis skin extract concentrations. The response measured included pH, moisture content, free alkali, emulsion stability, viscosity, inhibitory, test and preference test of the shampoo. Result showed that jeruk nipis skin shampoo effective inhibited T. metagrophytes and M. canis with inhibition zone of 29-34 mm and 32,3-36 mm. respectively addition of jeruk nipis skin extract affected the caracteristics of shampoo. Value of pH, moisture content, free alkali and emulsion stability of the shampoo with jeruk nipis skin extract were in the range of Indonesia National Standart for shampoo (SNI 06-2692-2002). The viscosity of shampoo with 3% extract addition was higher than that of Indonesian national Standard. Statistc analysis showed that the level of addition of jeruk nipis extract influenced pH, Value, moisture content, viscosity and emulsion stability of shampoo. Shampoo with 0,5% jeruk nipis extract was recommendedItem Karakteristik Pati Sagu Terasetilasi(2015-08-03) Rahmayuni; Hamzah, Faizah; Johan, Vonny Setiaries; HidayatiSago starch is now finding increasing application in various food products such as sago meals, noodles, sauce and edible film. Native sago starch exhibits relatively retrogradation resulting in the formation of a long cohesive gel with increased syneresis. In order to overcome drawbacks of native sago starch, chemical modifications can be carried out to improve its properties. Many types of chemical modifications have been applied to starches of various plant sources, such as acetylation method. Starch acetate was produced by acetylation method using acetate acid addition. The purpose of this research was to get the best reaction time from acetylation method. This research used the Complete Random Design (CRD) with three repetitions from five treatments that consist of SA1 (native sago starch), SA2 (reaction time 30 minutes), SA3 (reaction time 60 minutes), SA4 (reaction time 90 minutes) and SA5 (reaction time 120 minutes). The design response is used Duncan’s New Multiple Range Test (DNMRT) the level 5%. The result showed that the acetylation method of starch acetate with different reaction time gave the significantly effect to the moisture content, ash content and acetyl groups. The best treatment in this research is reaction time 90 minutes.Item Kualitas Bakso Berbahan Dasar Ikan Patin Dan Jantung Pisang Dengan Bahan Pengisi Substitusi Tepung Tapioka Dan Tepung Sagu(2015-08-01) Efendi, Raswen; Hamzah, Faizah; Ariani, Dyah AyuTujuan penelitian ini adalah untuk mengetahui pengaruh subsitusi tepung tapioka dan tepung sagu terhadap kualitas bakso ikan patin dan jantung pisang. Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) terdiri dari 5 perlakuan dan 4 ulangan: TS1 (tepung tapioka 100%), TS2 (tepung tapioka 75% dan tepung sagu 25%), TS3 (tepung tapioka 50% dan tepung sagu 50%), TS4 (tepung tapioka 25% dan tepung sagu 75%), TS5 (tepung tapioka 100%). Data yang diperoleh dianalisis secara statistik dengan menggunakan analisis sidik ragam (ANOVA), yang dilanjutkan dengan uji DNMRT pada taraf 5% jika F hitung ≥ F tabel. Hasil penelitian menunjukkan bahwa kombinasi tepung tapioka dan pati sagu berpengaruh terhadap kadar air, kadar abu, kadar pati, warna dan tekstur secara deskriptif, tetapi tidak berpengaruh terhadap mutu organoleptik warna, aroma, rasa, tekstur dan penilaian keseluruhan secara hedonik dari panelis. Hasil analisis semua perlakuan telah memenuhi Standar Nasional Indonesia bakso ikan (SNI 01-2346-2006) berdasarkan parameter kadar air, kadar abu dan kadar pati. Dalam pembuatan bakso jantung pisang dan ikan patin dapat digunakan bahan pengisi dengan rasio tepung tapioka sampai 100% atau pati sagu 100%.Item Tuntutan Pemanfaatan Ilmu dan Kimia Hasil Pertanian Dewasa ini(2012-11-11) Hamzah, FaizahIlmu kimia adalah ilmu yang mempelajari kimia reaksi, khususnya yang berkaitan dengan sifat-sifat kualitasnya, proses kerusakannya, cara-cara pengawetannya dan usaha memodifikasinya untuk memberikan nilai tambah yang memenuhi unsur-unsur yang lebih tepat sebagai biokatalisator dari bahan-bahan objek hasil-hasil pertanian untuk mencari senyawa-senyawa kimia yang aktif untuk dapat dipergunakan sesuai dengan apa yang diharapkan, sedangkan teknik kimia merupakan penggunaan teknologi dalam memanfaatkan bahan-bahan hasil pertanian secara kimiawi. Ilmu kimia hasil pertanian merupakan bidang interdisipliner, karena memperlihatkan ilmu lain terutama: bakteriologi, ilmu kimia organik, ilmu fisika dan keteknikan (Fennema, 2005). Sebenarnya kimia bahan hasil pertanian merupakan akses utama dari ilmu kimia karena mempelajari tentang komposisi, struktur, sifat-sifat bahan hasil pertanian dan kemungkinan perubahan kimiawi yang terjadi serta mencari senyawa baru untuk mengetahui kegunaan senyawa tersebut apakah sebagai obat-obatan atau sebagai makanan kesehatan, baik sifatnya sebagai makanan fungsional maupun sebagai makanan suplemen. Kimia bahan hasil pertanian sudah barang tentu sangat erat kaitannya dengan ilmu kimia, biokimia, kimia fisiologi, botani, zoologi, dan biologi molekuler.
