Abstract

Tujuan penelitian ini adalah untuk mempelajari pengaruh jenis dan konsentrasi penstabil terhadap mutu, serta kelayakan usaha selai kacang mete. Penelitian ini menggunakan rancangan acak lengkap faktorial (RAF), 2 faktor, yaitu: (a) jenis penstabil, yaitu: Span 80 (a1) dan Span 80+Tween 80 (a2); dan (b) konsentrasi penstabil, yaitu  0,5%(b1), 1%(b2), dan 1,5%(b3), dengan 4 kali ulangan. Mutu selai kacang mete yang diuji meliputi: parameter kimia, yaitu kadar air, kadar abu, kadar lemak, kadar protein dan karbohidrat; parameter fisik, yaitu kekentalan (viskositas); dan parameter organoleptik yaitu uji rasa, warna, aroma dan keseluruhan. Teknoekonomi produk selai kacang mete yang dianalisis dalam penelitian ini, meliputi Break even point (BEP), Payback Period, Return on Invesment (ROI), Benefit Cost ratio (B/C), Net Present Value (NPV) dan Internal Rate of Return (IRR). Hasil penelitian menunjukkan bahwa jenis dan konsentrasi bahan penstabil serta interaksi kedua variabel berpengaruh nyata terhadap kadar lemak selai kacang mete. Kadar air selai kacang mete dipengaruhi oleh jenis penstabil yang digunakan. Konsentrasi bahan penstabil berpengaruh terhadap kadar protein, kadar karbohidrat, viskositas, rasa, warna, aroma dan atribut keseluruhan dari selai kacang mete. Penambahan penstabil Span 80+Tween 80 dengan konsentrasi 1 % (a2b2) memberikan selai kacang mete dengan mutu terbaik. Hasil analisis teknoekonomi menunjukkan usaha selai kacang mete layak untuk dijalankan.

Abstract

This study aim was to determine lactagogue effect of torbangun leaves to plasma levels of lactogenic hormone and gene expression of their receptors in mammary glands of lactation rats. Lactagogue activity was evaluated by volume of milk was produced by the rats treated with commercial milk booster contained ‘katuk' leaves extract (AF), ethyl acetate fraction of torbangun leaves (EA), water extraction of torbangun leaves (AQ) and kaempferol (KP). Lactating rats (n=5) of Sprague dawley with six pups were fed with AF, EA, AQ, and KP in the amount of 50 mg/kg, 30 mg/kg, 80 mg/kg and 60 mg/kg body weight, respectively. The feed was given orally every two days and starting from day 2 after giving birth until day 28. The volume of milk was estimated by the increment pup weight after breastfed. The levels of serum lactogenic hormones were determined by ELISA methods. Moreover, in order to measure the gene expression of the lactogenic hormone's receptors in the mammary gland a real time - reverse transcription polymerase chain reaction (RT-PCR) method was performed. The results showed that ethyl acetate fraction of torbangun leaves (EA) (a) was not significantly stimulating the synthesis of serum prolactin and estradiol at day 14 and day 28 lactation period, (b) down-regulated the gene expression of estradiol receptor (ERα) at day 28, and (c) up-regulated the gene expression of prolactin receptor (PRLR) in mammary gland at day 14 and day 28. This study indicated that ethyl acetate fraction of torbangun leaves was induced milk production, within up-regulated the gene expression of prolactin receptor (PRLR) in the mammary gland of lactation rats.

Abstract

AbstrakIndonesia adalah negara dengan keanekaragaman hayati kedua terbesar di dunia. Banyak di antaranya merupakan tumbuhan yang bersifat fungsional dan memiliki manfaat untuk kesehatan manusia, salah satunya yaitu rebung. Perendaman dan perebusan merupakan cara umum yanng sering digunakan untuk pengolahan rebung sehingga rebung memiliki daya simpan yang rendah. Pengolahan lanjutan diperlukan untuk mempertahankan daya simpan rebung sebagai pangan fungsional, terutama melalui cara fermentasi. Tujuan penelitian ini adalah mempelajari efek konsentrasi garam dan lama fermentasi terhadap mutu fisiko-kimia, total bakteri asam laktat, dan organoleptik kimchi rebung (Deandrocalamus asper). Desain eksperimental dengan rancangan acak kelompok (RAK) dengan pola faktorial. Faktor kesatu (α) yaitu konsentrasi garam (3%, 5% dan 7%) dan yang kedua (β) yaitu lama waktu fermentasi (2 hari, 4 hari dan 6 hari) dengan tiga kali pengulangan. Karakteristik fisikokimia, total bakteri asam laktat dan organoleptik dari kimchi rebung dianalisis. Berdasarkan hasil penelitian didapatkan bahwa terdapatnya pengaruh konsentrasi garam, lama fermentasi serta interaksi keduanya terhadap kadar pH, serat kasar, dan daya terima rasa kimchi rebung. Total bakteri asam laktat rebung dan persen kadar air dipengaruhi dengan baik oleh konsentrasi garam, sedangkan kadar abu, lemak, protein, warna, aroma dan tekstur kimchi rebung dipengaruhi oleh lama fermentasi.Kata kunci: bakteri asam laktat, fermentasi, karakteristik kimia, kimchi, rebung AbstractIndonesia has abundant natural resources. Various types of plants can grow well and have properties that are beneficial to human health. One of the plants that grow well in Indonesia is bamboo shoots. Bamboo shoots has been being processed by soaking and boiling only, but the shelf life of bamboo shoots is still very low. Further processing to extend the shelf life of bamboo shoots as food and functional food should be done through fermentation. This study aims to determine the effect of salt concentration and fermentation time in physicochemical, microbial characteristics, and organoleptic of bamboo shoot kimchi (Dendrocalamus asper). The experimental design was a factorial randomized block design (RBD). The first factor (α) was salt concentration (3%, 5% and 7%) and the second factor (β) was duration of fermentation (2 days, 4 days and 6 days) with three times replication. Physicochemical characteristics, total lactic acid bacteria, and organoleptic of bamboo shoot kimchi were analyzed. The results showed that the concentration of salt, the duration of fermentation, and its interaction influenced pH value, crude fiber, and the taste of bamboo shoots kimchi. The salt concentration affected the moisture content and total lactic acid bacteria of bamboo shoots, meanwhile ash content, fat, protein, color, aroma, and texture of bamboo shoot kimchi influenced by fermentation time.Keywords: bamboo shoots, fermentation, kimchi, lactic acid bacteria, physicochemical
