    Graphene adalah bentuk 2D dari karbon dengan sifat-sifat unggul yang menarik untuk dikembangkan. Permasalahan yang kemudian muncul adalah proses sintesis massal yang masih menjadi kendala. Penelitian ini bertujuan untuk mensintesis material graphene secara kimiawi dengan menggunakan reduktor zinc dan metode hydrothermal dan menganalisa pengaruh varaiasi penambahan massa sebesar 0,8 gram, 1,6 gram, dan 2,4 gram zinc serta variasi temperatur hydrthermal 160áµ’C, 180áµ’C, 200áµ’C. Proses karakterisasi material graphene dilakukan dengan pengujian Scanning Electron Microscope (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared spectroscopy, Uji Iodine number, dan Four Point Probe digunakan untuk mengetahui nilai konduktivitas elektrik material. Morfologi dari graphene yang dihasilkan berbentuk lembaran-lembaran transparan dan disertai dengan kerutan pada permukaannya. Nilai konduktivitas elektrik terbesar dihasilkan dari variasi panambahan serbuk zinc sebesar 0,8 gram dan temperatur hydrothermal sebesar 200áµ’C dengan nilai sebesar 0,10281 S/cm dan bilangan iodine 11384,64

    This study aims to examine the value relevance of corporate social responsibility (CSR) information for measuring the company’s value. The sample used in this study is the companies included in the ASEAN Stars. The results show that accounting information, earnings, book value of equity, and operating cash flow are the relevant information. CSR information is relevant information because it can increase the value relevance of cash flow information, but is not able to increase the value relevance of earnings and book value information. CSR information is relevant, but its value relevance is not consistent. This indicates that the quality of CSR reports is still lacking and needs to be improved so that the relevance of its information value becomes greater and consistent. The results also indicate that the presence of book value and the cash flow information result in a decline in the value relevance of earnings information. Despite the decline in value relevance, the earnings information show the most consistent value relevance in all countries, which means that the earnings information is still the most relevant information for measuring the company’s value.   Keywords: value relevance, CSR, earnings, book value of equity, operating cash flo

    Bencana banjir merupakan bencana yang paling sering terjadi setiap tahun di Propinsi Jawa Tengah. Badan Penanggulangan Bencana Daerah (BPBD) sebagai instansi yang terkait kebencanaan bertanggung jawab menyediakan kebutuhan logistik. Penyediaan tersebut membutuhkan data kejadian bencana terbaru dari tim khusus BPBD di tempat kejadian. Tim tersebut bernama Tim Reaksi Cepat (TRC). TRC mengirimkan data terbaru melalui email ke BPBD untuk kemudian dianalisis secara manual. Tugas Akhir ini membangun sebuah Sistem Pendukung Keputusan (SPK) untuk suplai logistik bencana banjir di Jawa Tengah. Sistem dibangun dengan metode Proses Hierarki Analitik (PHA) dan berbasis web. Metode PHA menguraikan masalah pemberian bantuan logistik yang kompleks menjadi bagian-bagian yang sederhana berbentuk hierarki sehingga permasalahan menjadi lebih terstruktur dan sistematis. Sistem ini menggunakan lima kriteria pertimbangan yaitu, jumlah kematian, jumlah luka dan pengungsi, kerugian harta benda, kerusakan infrastruktur, dan daerah banjir. Hasil dari sistem adalah bahan pendukung yang dapat menjadi pertimbangan dalam pengambilan keputusan pemberian bantuan logistik

    In planning the procurement of goods and services the government city of Tangerang, will be compiled in a budget plan regional work units (RKA-on education) allocated from the Budget Revenue and Expenditure for Fiscal Year 2013, the compilation takes into account Standard Price of Goods. The problem faced now is the drafting, discussion and Standard Storage Unit Price still use the document to be signed by the Drafting Team and the Mayor of Tangerang as authorizing the Mayor's decision, and the data is stored in a file on Ms. Excel 2007. This proved to be less effective and time efficiency, especially when searching required by the standard price of sector departments. And waste paper for printing the books for sector departments in the form of a report each fiscal year. To overcome these problems were created Standards Information System using the web-based Goods Price CodeIgniter 2.0 framework and data storage using MySQL. With the construction of this system is expected to boost the quality of information transmission standard price of goods in the city of Tangerang
