Judul: Analisis Kesediaan Membayar (Willingness to Pay) Produk Healthy Nama NIM FoodBeras Merah Pulen di Serambi Botani, Botani Square, Bogor
Abstrak: Beberapa tahun terakhir ini, konsumsi beras merah dipopulerkan sebagai bagian dari gaya hidup sehat. Beras merah dengan konsep healthy food merupakan salah satu produk dari Serambi Botani. Penelitian ini bertujuan untuk menunjukkan adanya hubungan karakteristik responden dengan kesediaanya membayar, mengetahui nilai rataan kesediaan membayar, dan mengetahui faktor yang mempengaruhi pengunjung terhadap harga maksimal yang sanggup dibayarkan untuk produk healthy food beras merah pulen. Hasil dari penelitian ini yaitu hubungan karakteristik responden dan kesediaannya dalam membayar mayoritas berjenis kelamin perempuan dengan usia separuh baya yang memiliki jumlah anggota keluarga kecil dan berpendidikan terakhir strata 1 serta bekerja sebagai pegawai swasta berpenghasilan > Rp 7 500 000. Nilai rataan maksimum WTP untuk produk healthy food beras merah pulen adalah sebesar Rp 33 350 per satu kilogram dengan standar deviasi sebesar Rp 13 000. Faktor yang paling mempengaruhi responden dalam mengestimasi nilai WTP adalah jumlah anggota keluarga dan kepedulian terhadap pangan sehat dan bergizi.

Judul: Analisis Kesediaan Membayar (Willingness To Pay) Sayuran Organik dan Faktor - Faktor yang Mempengaruhinya (Studi Kasus Kota Bogor, Jawa Barat)
Abstrak: The era of modernization and the increasing in GDP per capita have changed the consumer behavior of Indonesian people. Indonesian people realize the importance of healthy living by consuming organic vegetables. The increasing production cost as a result of improving product quality induced the selling price of organic vegetables in market. This research aims to identify customer characteristics who made a purchase on organic vegetables by using descriptive analysis, to estimate consumer willingness to pay (WTP) using Contingent Valuation Method (CVM) and to analyze factors that influence the Willingness To Pay using Structural Equation Modeling (SEM) with LISREL. The result of this research showed the mean of maximum WTP for cabbage commodity is Rp 18.738; lettuce is Rp 30.048; broccoli is Rp 40.250; chinese cabbage (bok choy) is Rp 24.368 and carrot is Rp 19.820. The attitude and obstacle effect on WTP is significant, while the effect of SES is not significant.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
