Judul: BACKEND MODULE FOR WEBGIS HISTORY OF ROAD DAMAGE IN WEST JAVA PROVINCE
Abstrak: Kerusakan jalan merupakan suatu kondisi jalan yang terstruktur dan fungsional tidak dapat secara optimal melayani perlintasan. WebGIS merupakan alat yang dapat mengelola data kerusakan jalan. Saat ini sudah terdapat WebGIS Sobat Jabar yang menampilkan tentang kondisi kerusakan jalan, namun data yang ditampilkan belum terintegrasi dengan database. Penelitian ini bertujuan untuk membangun modul backend riwayat kerusakan jalan yang mampu menyediakan data tentang kondisi jalan dan menjamin keamanan serta aksesibilitas pengambilan data sehingga memudahkan pengguna dalam mengakses informasi kondisi jalan yang lebih detail di wilayah Jawa Barat. Metode yang digunakan dalam penelitian ini adalah Prototype, karena dapat mendefinisikan tujuan dibangunnya perangkat lunak, dan dapat mengidentifikasi kebutuhan secara rinci untuk fungsi dan fitur dalam perangkat lunak. Penelitian ini berhasil membuat dan mengimplementasikan modul backend ke dalam WebGIS Sobat Jabar. Modul backend yang dikembangkan seperti fitur register, login, pencatatan titik kerusakan jalan, dan beberapa fitur tambahan lainnya. Keberhasilan penelitian ini ditandai dengan hasil pengujian secara black box testing yang telah memenuhi harapan peneliti., Road damage is a condition where the structured and functional road cannot optimally serve the crossing. WebGIS is a tool that can manage road damage data. Currently there is a West Java WebGIS which displays the condition of road damage, but the data displayed is not yet integrated with the database. This research aims to build a backend road damage history module that is able to provide data about road conditions and ensure the safety and accessibility of data collection, making it easier for users to access more detailed road condition information in the West Java region. The method used in this research is Prototype, because it can define the purpose of building the software, and can identify detailed requirements for functions and features in the software. This research succeeded in creating and implementing a backend module into West Java

Judul: Development of Front End Module Webgis  Visualization Of Road Damage History Of West Java Province
Abstrak: Kapasitas dan kualitas jalan berkaitan erat dengan mobilitas penduduk dan penyediaan barang serta jasa untuk memenuhi kebutuhan masyarakat. WebGIS telah menjadi alat penting dalam pemantauan kondisi jalan. Sistem ini memungkinkan pemerintah dalam melakukan perencanaan, pengecekan, maupun pemrograman kondisi jalan secara berkala dan berkelanjutan. Sobat Jabar merupakan webgis yang menampilkan informasi data peta kondisi jalan secara visual untuk memudahkan pengguna dalam analisis data dan pengambilan keputusan. Penelitian sebelumnya terbatas pada visualisasi kondisi jalan dengan foto dan video. Penelitian ini mengembangkan fitur history kerusakan jalan Provinsi Jawa Barat menggunakan metode prototyping dengan lima tahapan yaitu communication, quick plan, modeling quick design, construction of prototype, deployment, delivery and feedback. Pengembangan dilakukan menggunakan bahasa pemrograman Javascript dengan library ReactJs dan LeafletJs. Hasil pengujian sistem dengan metode blackbox testing menunjukkan keberhasilan dalam menampilkan informasi kerusakan jalan secara visual berupa foto dan video, melaporkan kondisi jalan rusak, memberikan komentar, serta membaca dan mengedit history kerusakan pada tabel admin untuk melakukan update penanganan yang sudah dilakukan., Road capacity and quality are closely related to population mobility and the provision of goods and services to meet community needs. WebGIS has become an important tool in monitoring road conditions. This system allows government to plan, check, and program road conditions on a regular and continuous basis. Sobat Jabar is a webgis that displays road condition map data information to facilitate users in data analysis and decision making. Previous research was limited to visualizing road conditions with photos and videos. This research develops road damage history feature for West Java Province using the prototyping method with five stages, communication, quick plan, modeling quick design, construction of prototype, deployment, delivery and feedback. Development was carried out using the Javascript programming language with the ReactJs and LeafletJs libraries. The results of system testing using blackbox testing method show success in visually display road damage information in the form of photos and videos, reporting road damage conditions, writing a comment, and reading and editing damage history in the admin table to update the handling that has been done.

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.
