Dengan meningkatnya kesadaran pelanggan akan produk dan layanan, serta adanya tantangan akan kompetisi terbuka di bidang jasa telekomunikasi memaksa operator-operator telekomunikasi untuk meningkatkan pelayanan yang lebih baik agar bisa bertahan dan memenangkan kompetisi. TELKOM mengantisipasi lingkungan bisnis tersebut dengan mengembangkan Sistem Informasi (SI) yang berkaitan dengan peningkatan pelayanan kepada pelanggannya yang dikenal sebagai Customer Care and Billing System dan diberi nama "SISKA (Sistem Informasi Kastemer)". Implementasi yang tidak tepat dari SI dapat menimbulkan kerugian keuangan, sehingga diperlukan evaluasi nilai ekonomis dari pemanfaatan SI. Dengan metodologi IE, nilai ekonomis dari investasi SI dapat dievaluasi baik melalui pendekatan keuangan (financial approach) seperti Return On Investment (ROI), Net Present Value (NPV), dan Payback Period., maupun pendekatan non keuangan (non financial approach) seperti penilaian domain bisnis dan teknologi. Dari kedua pendekatan tersebut bisa memberikan gambaran yang lebih baik dari investasi SI. Tesis ini memfokuskan pada penerapan metodologi IE untuk mengukur nilai ekonomis SISKA. Pada pendekatan keuangan dilakukan kuantifikasi manfaat seperti peningkatan akurasi billing pada VL Billing, percepatan penyelesaian pasang barn dan gangguan pada VA (PSB+GGN). Pada pendekatan non keuangan dilakukan evaluasi seperti keselarasan antara business objective dan SIS planning TELKOM dengan SISKA. ...... The increasing customer awareness of products and services, and an open competition challenge m telecommunication serv1ces sector are forcing telecommunication operators to improve their services to sUfVlve and win the competition. TELKOM anticipates this business environment by developing Information System (IS) that related with increasing services to their customers known as "Customer Care and Billing System" and named SISKA (Sistem Informasi Kastemer). Improper implementation of IS can lead to a fmancial losses, so evaluation of economics value from IS is needed. With IE methodology, economics value of IS investment can be evaluated through fmancial approach such as Return On Investment (ROI), Net Present Value (NPV) , and Payback Period as well as through non financial approach such as business and technology domain assessment. Both approaches can give a better understanding ofiS investment. This thesis focuses on the implementation of IE methodology to measure economics value of SISKA. In fmancial approach, quantification of benefit produces among other, increasing of billing on Value Linking Billing, Accelerating of new line installation and line faulty. In non fmancial approach, evaluation of aligning between business objective and Strategic Information System Planning TELKOM with SISKA has been examined.

ABSTRAK Teknologi informasi merupakan salah satu alat untuk meningkatkan produktivitas perusahaan serta meningkatkan daya saing perusahaan. Tetapi tidak jarang investasi teknologi informasi malah menjadi pengeluaran yang sia-sia. Untuk itu perlu dilakukan justifikasi finansial. Penghitungan justifikasi tradisional seperti traditional cost-benefit analysis masih beluin optimal. Pada penghitungan traditional cost-benefit analysis ada manfaat yang tidak bisa dikuantifikasi secara finansial, karena banyak manfaat penerapan TI dalam perusahaan bersifat intangible. Information economics yang diperkenalkan oleh Marylin M. Parker menjawab masalah tersebut. Melalui teori ini maka manfaat dan biaya proyek TI dapat dikuantifikasi, dengan menambahkan nilai-nilai yang diperoleh misalnya peningkatan kinerja sebuah fungsi, percepatan perolehan hasil suatu fungsi, peningkatan produktivitas dan sebagainya kedalam manfaat. Disamping itu juga dapat dilakukan pengkajian terhadap faktor-faktor business domain dan technology domain. Tesis ini menerapkan konsep information economics dalam mengevaluasi proyek penerapan Intranet di BTN. Hasil dari pengamatan dapat diketahui bahwa proyek Intranet BTN memiliki nilai yang strategis bagi BTN dalam menghadapi pesaingnya. Dan juga merupakan proyek yang strategis bagi pengembangan bisnis di STN.

ABSTRACT The information technology is one of the instruments to increase the business productivity and business competition. However, the investment of information technology sometimes can become worthless. Therefore, we must make a financial justification. The traditional justification such as traditional cost-benefit analysis is not yet optimal because there exists a benefit which cannot he financially quantified or intangible. The information economics introduced by Marylin M. Parker solves this problem. Using her theory the benefit and cost of the information technology project can be quantified, by adding the values that we have got such as the intensification performance of a function, the product acceleration of a function, increasing the productivity, et cetera into benefit. Besides, we can also study about the factors of the business domain and technology domain. In this thesis we report the application of the information economics concept to evaluate the use of the Intranet in BTN. The result of this application shows that the Intranet project yields a competitive advantage for BTN to face its competitors and this project is strategic to develop business in BTN.

The ecological role of mangrove ecosystem is economically, socially and physically, highly significant. Despite the many benefits provided by mangroves, they tend to be under intense pressure from competing resource used by local vullagers, in particular, as firewood, or charcoal. The ecosystem is typically crucial, hence the benefits and values need to identify and estimate economically. The objectives of this research are: (1) to identify economic values of mangroves based on ecosystem benefits; and (2) to estimate total economic value (TEV) of "use-value" and "non-use value" of mangroves. The method of economic valuation was applied to estimate TEV based on the benefits of mangroves ecosystem (direct-use value, indirect-use, option use, and existence use values). Results of this research are as follows. (1) Functions and benefits of the mangrove ecosystem in the village of Tawiri Consisted of direct-use (fuel wood collection for the subsistence needs of local villagers, wild animals used by humans for subsistence purposes, near by fishing activities); indirect-use (natural barrier to shoreline erosion, highly nutritious food source for animals in the mangrove area), option use (biodiversity bnfits), and existence use (WTP). (2) The TEV of mangrove was Rp 24,887,887 per year, consisting of direct-use value of Rp 11,299,500 per year (45.40%), indirect-value of Rp 9,098,077 per year (36.56%), exixtence value of Rp 4,083,750 per year (16.41%) and optionvalue of Rp 406,560 per year (1.63%).
