Judul: Design policy models and strategies of service level management of toll roads (Jakarta- cikampek toll roads case study)
Abstrak: Toll roads are public roads that are part of road network system and a national road users are required to pay tolls. While the definition of highway is a certain amount of money paid for the use of toll roads. Minimum service standards under the authority of the central government (Article 2 paragraph 4 item b.). MSS held to ensure the availability of the service road to the public in the most minimum conditions. Minimum Service Standards for toll roads has been provided for in Regulation Minister of Public Works No. 392/PRT/M/2005. MSS is a measure that must be achieved in the implementation of toll road and organized to improve the public service as a toll road users. The purpose of this study is the subject as follows (1) Model determined the policies and strategies capable of dealing with problems of the physical condition of highways, traffic management and land use and maintain the level of highway service (MSS) remains appropriate, and (2) Realization of environmental management model that can address environmental issues in order to prevent or reduce air pollution caused by transportation and traffic noise in the area around the highway. Results showed that growth in traffic volume on toll roads is quite high, if not controlled it will result in the management and operation of toll roads including the physical condition of the components of toll roads, traffic management and land use components will result in a decreased level of highway service or in other words Standard Minimum Service (MSS) is not fulfilled (Minimum Service Standards in accordance Regulation Minister of Public Works No. 392/PRT/M/2005), and growth of high traffic volumes will result in environmental problems in this study was limited only to the level of air pollution and noise levels that occur on the interstate.

Judul: Development of Spatial Data Management System for Toll Road Assets (Case Study of Bakauheni-Terbanggi Besar Toll Road Section)
Abstrak: Jalan tol merupakan infrastruktur yang memegang peranan penting dalam meningkatkan kesejahteraan ekonomi, sehingga aset-aset yang terkait dengan jalan tol perlu dikelola dengan baik. Kini, pengelolaan aset jalan tol dinilai sulit karna masih dilakukan secara manual dengan data yang sangat banyak. Salah satu solusinya adalah dengan menggunakan suatu Road Asset Management System (RAMS) berbasis geospasial yang dapat mempermudah pengelolaan aset jalan tol secara digital. RAMS telah dikembangkan di berbagai negara, namun di Indonesia sendiri penerapannya masih sangat minim. Penelitian ini bertujuan untuk memperbaiki, melengkapi, dan mengintegrasikan basis data RAMS yang sudah ada pada penelitian sebelumnya dan mengimplementasikannya pada suatu sistem manajemen aset jalan tol sederhana. Data yang digunakan merupakan data spasial dan non-spasial aset jalan tol ruas Bakauheni-Terbanggi Besar. Sistem dikembangan menggunakan Y-Model Webgis Methodology (YWDM) dengan bahasa pemrograman HTML, PHP, JavaScript, dan CSS. RAMS yang dikembangkan berupa sebua WebGIS yang terhubung dengan REST API data aset jalan tol dan dapat menampilkan visualisasi aset jalan tol pada peta online OpenStreetMap, menambahkan aset baru menggunakan file GeoJSON, mencari dan melihat rincian aset, serta melihat rekap aset dalam bentuk grafik. Data aset seperti identifikasi jalan, ramp, akses, rambu jalan, lampu jalan, dan lainnya dengan total 51 tabel data spasial dan 31 tabel data non-spasial tersimpan dalam basis data PosgreSQL. Pengguna yang dapat mengakses sistem ini terbagi atas dua peran, yaitu admin yang dapat mengelola aset seperti pemerintah pusat, pemerintah daerah, BPJT, dan BUJT. Serta publik yang hanya dapat melihat visualisasi dan detail aset. Pengujian fungsionalitas yang dilakukan menunjukkan bahwa sistem dapat berjalan dengan baik., Toll roads are infrastructure that plays an important role in improving economic welfare, so assets related to toll roads need to be managed properly. Now, the management of toll road assets is considered difficult because it is still done manually with a lot of data. One solution is to use a geospatial-based Road Asset Management System (RAMS) that can facilitate the management of toll road assets digitally. RAMS has been developed in various countries, but in Indonesia itself the application is still very minimal. This research aims to improve, complete, and integrate the existing RAMS database in previous studies and implement it in a simple toll road asset management system. The data used is spatial and non-spatial data of the Bakauheni-Terbanggi Besar toll road assets. The system was developed using Y-Model Webgis Methodology (YWDM) with HTML, PHP, JavaScript, and CSS programming languages. RAMS developed in the form of a WebGIS connected to the REST API of toll road asset data and can display visualization of toll road assets on OpenStreetMap online maps, add new assets using GeoJSON files, search and view asset details, and view asset recaps in graphical form. Asset data such as road identification, ramps, access, road signs, street lights, and others with a total of 51 spatial data tables and 31 non-spatial data tables are stored in the PosgreSQL database. Users who can access this system are divided into two roles, namely admins who can manage assets such as the central government, local governments, BPJT, and BUJT. As well as the public who can only see visualizations and

Judul: Prenilasi Senyawa β-Diketon sebagai Prekursor 3-Prenilflavon
Abstrak: One group of flavonoids that has not been commonly synthesized is 3- prenylflavone. The main objective of this experiment was to synthesize precursor of 3-prenylflavone. Firstly, β-diketone was synthesized via 4 steps from phenol as starting compound with total yield of 24%. Prenylation of β-diketone with prenyl bromide and K2CO3 base produced 4 fractions which were separated by using preparative thin layer chromatography (PTLC) with n-hexane:EtOAc (8:2) as the eluent. Fraction with Rf = 0.80 was further separated by using preparative PTLC with n-hexane:EtOAc (99:1) as the eluent. Two fractions were obtained with Rf = 0.38 and 0.42. The first fraction has been characterized as diprenylated β-diketone with 49% yield. Application of protecting group on the phenolic OH group in β- diketone are needed to obtain monoprenylated β-diketone which can be further cyclized into 3-prenylflavone
