Judul: Mapping for Anyer Highway Maintenance using Geographic Information System
Abstrak: Kawasan Pantai Anyer setiap tahunnya selalu mengundang wisatawan untuk berkunjung. Akses bagi wisatawan maupun masyarakat sekitar adalah melalui Jalan Raya Anyer. Ada beberapa penghambat dalam mobilisasi baik masyarakat maupun wisatawan, yakni terdapat beberapa titik dengan kondisi jalan yang rusak. Tujuan penelitian ini adalah mengidentifikasi kodisi jalan serta memodelkan kondisi jalan tersebut ke dalam peta menggunakan system informasi geografis. Metode yang digunakan merupakan metode skor dimana penilaiain kondisi jalan sudah diatur oleh Direktorat Jenderal Bina Marga. Jalan Raya Anyer berperan sebagai jalan kolektor dengan tipe jalan 2/2 UD. Perkerasan yang digunakan berupa perkerasan lentur dengan panjang sebesar 27313,3 dan lebar sebesar 7,5 meter. Panjang yang diamati pada penelitian kali ini sebesar 13870 meter. Nilai lintas haran rata-rata Jalan Raya Anyer adalah 1852 kendaraan per jam dengan kelas lalu lintas 4. Jalan dibagi kedalam 14 segmen dengan nilai kondisi jalan masing-masing 1 – 9 sebesar 6, 4, 2, 2, 7, 2, 4, 3, 3, 4, 4, 4, 2, dan 3. Urutan prioritas pemeliharaan yakni pemeliharaan berkala pada segmen 5 dengan presentase sebesar sebesar 7,143 %, sedangkan kategori pemeliharaan rutin sebesar 92,857 %., Anyer Beach area every year always invites tourists to visit. Access for tourists and the surrounding community is via Jalan Raya Anyer. There are several obstacles to the mobilization of the community and tourists; namely, several points have damaged road conditions. The purpose of this study is to identify road conditions and model the road conditions into a map using a geographic information system. The method used is a scoring method where the Directorate General of Highways has regulated the assessment of road conditions. Jalan Raya Anyer acts as a collector road with a road type of 2/2 UD. The pavement is flexible, with a length of 27313.3 and a width of 7.5 meters. The size observed in this study was 13870 meters. The average daily traffic value of Jalan Raya Anyer is 1852 vehicles per hour with traffic class 4. The road is divided into nine segments with priority values 1 – 14 of 6, 4, 2, 2, 7, 2, 4, 3, 3, 4, 4, 4, 2, and 3. The order of maintenance priority is periodic maintenance in segment 5 with a percentage of 7,143 %%, and the rest of the other segments are regular maintenance with a rate of 92,857 %.

Cikampak Cicadas to Jalan Segog Pamijahan
Abstrak: Jalan memiliki peran yang penting dalam menunjang kelancaran aktivitas masyarakat. Oleh karena itu, penelitian ini bertujuan mengidentifikasi jenis dan tingkat kerusakan dari perkerasan jalan dan drainase serta menentukan rekomendasi penanganan untuk perkerasan jalan dengan metode Bina Marga. Hasil dari penelitian menunjukan jenis kerusakan dengan luas permukaan terbesar adalah retak memanjang dengan luas total 582,44 m2, dan retak lateral adalah kerusakan dengan luas permukaan terkecil, yaitu 6,27 m2. Tingkat kerusakan cukup tinggi dialami oleh 18 segmen jalan, yang ditandai dengan perolehan nilai kondisi jalan 7. Rekomendasi berupa pemeliharaan rutin, pemeliharaan berkala dan penambahan secara berturut-turut pada drainase sisi timur 27, 18, dan 10 segmen sedangkan pada drainase sisi barat 35, 14, dan 6 segmen. Rekomendasi penanganan pada jalan diperoleh hasil 10 segmen jalan memerlukan pemeliharaan rutin, 26 segmen jalan memerlukan pemeliharaan berkala dan 19 segmen jalan memerlukan peningkatan dengan biaya penanganan yang diperlukan secara berturut-turut Rp 39.857.105, Rp Rp 302.529.219 dan Rp 1.719.020.425., Roads have an important role in supporting the smooth running of community activities. Therefore, this research aims to identify the type and level of damage to road pavement and drainage and determine treatment recommendations for road pavement using the Bina Marga method. The results of the research show that the type of damage with the largest surface area is longitudinal cracks with a total area of 582.44 m2, and lateral cracks are damage with the smallest surface area, namely 6.27 m2. A fairly high level of damage was experienced by 18 road segments, which was indicated by obtaining a road condition score of 7. Recommendations in the form of routine maintenance, periodic maintenance and successive additions on the east side drainage were 27, 18 and 10 segments while on the west side drainage it was 35, 14, and 6 segments. Recommendations for road handling were obtained as a result of 10 road segments requiring routine maintenance, 26 road segments requiring periodic maintenance and 19 road segments requiring improvement with the required handling costs being Rp 39.857.105, Rp 302.529.219 and Rp 1.719.020.425.

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.
