Abstract

The objective of this research was to study the potential of cherry leaf extract as natural sanitizer agent for Alabio eggshell in hatching process. A number of 533 of Alabio hatching eggs were used in this study. Hatching eggs produced from College of Vacational Studies IPB University, were collected three times a day. Three hundred thirty-three hatching eggs were divided into five treatment groups. The first group was considered as control, the second was dipping into commercial disinfection, and the third and the fifth gruop were dipping into cherry leaf extract 250 ppm, 500 ppm, and 750 ppm respectively. The results showed cherry leaf extract has secondary metabolite compounds : alkaloids, flavonoids and tannins. All of these secondary metabolite compounds have a role as antibacterial agent. cherry leaf extract 750 ppm shows the same potential as commercial disinfectants in reducing the microbial population in eggshells. The dipping treatment of 750 ppm cherry leaf extract in alabio duck hatching eggs resulted in the lowest embryo mortality rate compared to other treatments (9.3%). Key words: Alabio duck, cherry leaf extract, hatchery, total plate count of eggshell

Abstract

ABSTRACTThe method of extraction and the type of solvent used during extraction will influence effectiveness of the extraction and compound extracted. The aim of this research was determined the effect of extraction methode and solvent polarity on total phenolic content of cherry leaves (Muntingia calabura L). Extraction of cherry leaves used maceration and soxhelation methods with ethanol and chloroform as solvents. The total phenolic contain was determined by visible spechtrophotometer at 765 nm. It has been showed that the soxhletation method was a higher yield value than the maceration methods with the highest yield value showed by ethanol extract, it was 13,29% w/w. Otherwise maceration method showed a higher total phenolic contain with the highest total phenolic contain showed by ethanol extract, it was 10,70% GAE.

Abstract

Snack bars are snacks that can be consumed as ready-to-eat snacks, usually made from various nuts. In this study, banana jackfruit flour (Musa Pardisiaca) was used as the basic ingredient by utilizing local jackfruit banana flour from Subang, West Java. The purpose of this research is to make snack bar products by utilizing banana flour which can increase the selling price. Research activities start from the processing and packaging of snack bars to calculating product selling prices. This newly developed snack bar is made with jackfruit banana flour, honey, butter, chocolate, oats, peanuts, banana chips, sugar and eggs, has a sweet, crunchy and fragrant taste. The high calorie and fiber source of this banana jackfruit flour-based snack bar was well received by all panelists and has a pleasant sensory quality. These results indicate that banana jackfruit flour-based snack bars can be marketed as nutritious and delicious snacks. With this research, it is hoped that it can make snack bar products that have better nutritional content and can utilize banana flour, increase sales value and can expand the market for banana jackfruit flour, snack bars, and other diversified products that are not only sold in local markets but also through modern markets and online markets ABSTRAK Snack bar merupakan makanan ringan yang dapat dikonsumsi sebagai camilan ready to eat, biasanya terbuat dari berbagai kacang-kacangan. Pada penelitian kali ini menggunakan bahan dasar tepung pisang nangka (Musa Pardisiaca) dengan memanfaatkan tepung pisang nangka lokal asal Subang, Jawa Barat. Tujuan dari penelitian ini adalah untuk membuat produk snack bar dengan memanfaatkan tepung pisang yang dapat meningkatkan harga jual. Kegiatan penelitian dimulai dari pengolahan dan pengemasan snack bar hingga menghitung harga jual produk. Snack bar yang baru dikembangkan ini dibuat dengan tepung pisang nangka, madu, mentega, cokelat, oat, kacang tanah, keripik pisang, gula, dan telur, memiliki rasa yang manis, renyah, dan wangi. Sumber kalori dan serat yang tinggi dari snack bar berbahan dasar tepung pisang nangka ini diterima dengan baik oleh semua panelis dan memiliki kualitas sensorik yang menyenangkan. Hasil ini menunjukkan bahwa snack bar berbahan dasar tepung pisang nangka dapat dipasarkan sebagai makanan bergizi dan makanan ringan yang lezat. Dengan adanya penelitian ini diharapkan dapat membuat produk snack bar yang memiliki kandungan gizi yang lebih baik serta dapat memanfaatkan tepung pisang, meningkatkan nilai jual dan dapat memperluas pasar tepung pisang nangka, snack bar, dan produk diversifikasi lainnya yang tidak hanya dijual di pasar lokal tetapi juga melalui pasar modern dan pasar online.
