Judul: Analisis Lalu Lintas Harian Rata-rata dengan Kondisi Perkerasan Jalan Raya Jati Asih Kota Bekasi
Abstrak: Peningkatan jumlah kendaraan darat menimbulkan pembebanan berlebih pada jalan yang dilalui kendaraan darat tersebut. Hal ini dapat menimbulkan kerusakan jalan yang merugikan bagi pengguna jalan. Penelitian ini bertujuan untuk menganalisis hubungan antara intensitas arus lalu lintas harian rata-rata dengan tingkat kerusakan jalan dan merancang tebal perkerasan yang baru bila diperlukan. Penelitian ini dilakukan di Jalan Raya Pekayon arah Jati Asih dan Juanda, Bekasi. Perhitungan tebal perkerasan lentur menggunakan metode manual desain perkerasan (MDP) 2013 dengan pemeriksaan metode Pt T-01-2002-B dan metode SNI 03-1732-1989-F. Intensitas arus lalu lintas harian rata-rata yang tinggi yaitu DS = 0.81 merupakan salah satu penyebab kerusakan jalan di kedua arah Jalan Raya Pekayon. Dibandingkan dengan Pt T-01-2002-B dan SNI 03- 1732-1989-F, maka tebal perkerasan yang efektif didapatkan dari metode MDP 2013 dengan tebal lapisan permukaan 150 mm CTB, 150 mm LPA kelas A, 220 mm AC BC serta 50 mm AC WC.

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: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
