Judul: Analisis Segmentasi Pasar Dan Citra Merek Pada Beberapa Merek Kartu Gsm Dengan Analisis Korespondensi Berganda
Abstrak: Pesatnya pertumbuhan bisnis telekomunikasi seluler memicu kehadiran operator-operator. Banyaknya operator telekomunikasi selular yang menawarkan berbagai macam merek kartu GSM (Global System of Mobile Communications) menimbulkan persaingan yang ketat. Oleh karena itu, penyelenggara operator telekomunikasi seluler membutuhkan strategi pemasaran, seperti melakukan segmentasi pasar dan mengidentifikasi citra merek produk tersebut. Analisis yang digunakan pada penellitian ini adalah analisis korespondensi berganda. Hasil penelitian menunjukkan bahwa kartu TRI, IM3, dan AS memiliki segmen pasar yang relatif sama. Kesamaan segmen pasar juga terlihat pada SIMPATI dan XL. Kesamaan segmen pasar menunjukkan adanya persaingan antar merek tersebut dalam merebut pelanggan. Hasil analisis citra merek berdasarkan alasan memilih merek terlihat bahwa TRI, AXIS, IM3, dan XL memiliki citra merek yang relatif sama. Citra merek yang relatif sama juga terjadi pada AS dan SIMPATI.

Judul: Metode CHAID dan Korespondensi untuk Segmentasi Pasar dan Pemetaan Brand Image pada Beberapa Merek Kartu GSM.
Abstrak: One of the comunication tools that are nesisity and supports our needs in this era is mobile phone or often called HP (Hand Phone). Therefore it increases the buiness competition between provider companies in Indonesia. Hence, producers will increase their efforts to conduct evaluation and innovation on their products. These efforts, include maintaning and/or increasing market segmentation and making good impression about their product to consumers. One of the analysis that can be used for evaluating market segmentation and measuring brand image measuring are CHAID and correspondence. CHAID show that there were two segments which are 15-25 years old and 26-35 years old. The consumers have an impressions which support CHAID results. The results indicate that IM3 has a ‘cheap conversation tariff’ impression, 3 (TRI) has a ‘for school childern’impression, XL has a ‘fast internet access’ impression, AXIS has a ‘inexpensive short message service’ impression, Simpati has a ‘for executive/proffesional’ impression, and AS has a ‘the modern simcard’ impression. In general, it can be said that people who are 15-25 years old prefer using XL, AXIS, and 3 (TRI) as their provider, meanwhile people who are 26-35 years old like using Simpati.

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.
