Judul: Analisis persepsi karyawan operasional terhadap pelaksanaan Gardu Tol Otomatis (GTO) dan faktor-faktor produktivitas kerja pada PT Jasa Marga (Persero) Tbk Cabang Purbaleunyi
Abstrak: Kebutuhan masyarakat akan jaringan jalan semakin terdesak seiring dengan peningkatan produksi kendaraan yang tidak sebanding dengan kapasitas jalan yang ada. Terjadinya ketidakseimbangan tersebut salah satunya akibat pertumbuhan volume kendaraan roda empat yang naik sebesar 9% per tahun, sedangkan penambahan panjang jalan dilakukan hanya sebesar 0.01% per tahun, kondisi ini menjadi pemicu terjadinya masalah kemacetan lalu lintas. Konsep tol menjadi sebuah jawaban terhadap tingginya kebutuhan pengembangan jaringan jalan meskipun dalam kondisi anggaran pemerintah yang terbatas. PT Jasa Marga (Persero) Tbk merupakan satu-satunya Badan Usaha Milik Negara (BUMN) yang berperan sebagai pengembang sekaligus operator jalan tol di Indonesia yang memiliki sembilan Cabang, salah satunya adalah Cabang Purbaleunyi. Karakteristik Cabang Purbaleunyi adalah masalah antrian pajang pada gerbang tol. Untuk mengatasi masalah antrian tersebut maka dibuat Gardu Toll Otomatis (GTO), yang merupakan ide kreatif dari Gugus Kendali Mutu Pasteur. GKM Pasteur merupakan salah satu kelompok unit kerja yang ada di Cabang Purbaleunyi pada Gerbang Tol Pasteur. Perusahaan menganggap GTO dapat memberikan dampak positif bagi karyawan operasional.

Judul: Analisis Risiko Operasional Jalan Tol Jagorawi PT Jasa Marga (Persero) Tbk
Abstrak: A large number of vehicles in big cities led to traffic density, until people start switching to use the toll road. Jagorawi is one of the densest toll road, where high flows of traffic cause various risks which related to the operation of toll road. The purpose of this research is to determine the operational risk of Jagorawi toll road and determine the alternative strategies for the smooth operation of toll road. Method of sampling used is non probability sampling with purposive sampling technique. Data analyzed by using cause and effect analysis, Failure Mode Effect Analysis, and Analytical Hierarchy Process. The result indicates that the main risk which has been priority is traffic risk and the highest risk variabel of 21 risk variabels is the delay of infrastructure handling. The right alternative strategy to handle the mentioned risk is by educate the toll road users and inhabitants, develop the instrastructure, invest in quality of human resource, auto gate, and improve the service and safety.

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.
