Judul: Analisis Risiko Produksi Bunga Potong Gerbera (Herbras) pada PT Hilal Perdana Kreasi Kabupaten Cianjur
Abstrak: PT Hilal Perdana Kreasi adalah salah satu perusahaan pembudidaya bunga potong gerbera yang usahanya tidak terlepas dari risiko. Adanya pengaruh faktor lingkungan dan manusia menyebabkan terjadinya fluktuasi produksi dengan tren penurunan produksi dan produktivitas. Fluktuasi dengan tren penurunan mengindikasikan adanya risiko produksi yang dihadapi perusahaan. Tujuan penelitian ini adalah mengidentifikasi sumber risiko produksi, menganalisis kemungkinan terjadi nya risiko (probabilitas) dan dampak serta merumuskan alternatif strategi yang dapat direkomendasikan kepada perusahaan. Hasil identifikasi sumber risiko menggunakan metode deskriptif terdapat dua sumber risiko yaitu tenga kerja dan penyakit. Analisis probabilitas menggunakan metode z-score menghasilkan urutan probabilitas dari yang terbesar sampai terkecil adalah tenaga kerja dan hama. Analisis dampak menggunakan metode Value at Risk menghasilkan dampak terbesar hingga terkecil secara berurutan adalah tenaga kerja dan hama. Startegi preventif dilakukan untuk sumber risiko tenaga kerja sedangkan strategi mitigasi untuk risiko tenaga kerja dan hama.

Judul: Analisis Risiko Produksi Bunga Krisan Potong pada Perusahaan Berkah Flora di Kecamatan Megamendung, Kabupaten Bogor
Abstrak: Floriculture products which ranks the highest as well as an opportunity to developed compared to other products is the Chrysanthymum morifolium. Berkah Flora is one of the Chrysanthymum morifolium growers whose business is inseparable from the existence of a risk . The influence of environmental factors and human factor caused fluctuations in Chrysanthymum morifolium production and productivity of intersection. These fluctuations are an indication of the production risks facing the company. The purpose of this research is to identify the source of production risk, probalitity analysis, implication and alternative strategic for handling Chrysanthymum morifolium type standard and a spray. The results of the identification of the source of production risk is obtained by using descriptive analysis of risk sources including pests, diseases, weather and labor. Probablitas analysis results use z – score method at both the type of Chrysanthymum morifolium have different rank from highest to smallest are the source of the risk of pests , diseases , weather , labor ( standard type ) and pests , disease , weather , labor (type spray ) . Implication Analysis use Value at Risk method at both types of Chrysanthymum morifolium have different rank from the highest to smallest are risk of pests , weather , labor , disease ( standard type ) and pests , disease , weather , labor ( spray type ) . Preventive Startegic conducted for risk of pests and diseases, while Mitigation Startegic conducted for risk of pests, diseases,weather, and labor.

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.
