Judul: Domain name system dinamis dengan protokol dinamid versi 1.02
Abstrak: Pengalamatan suatu host di jaringan TCP/IP dilakukan dengan menggunakan alamat IP. Sulit sekali bagi manusia untuk mengingat semua host di jaringan lengkap dengan alamat IPnya. Karena itu dibuatlah pemetaan nama ke alamat IP ke dalam suatu file HOST. TXT. Namun dengan cara ini, setiap host akan memiliki salinan HOST.TXT yang sama yang berarti adanya redundansi yang tidak perlu. Karena itu dibuat mekanisme Domain Name System (DNS) yang merupakan database tersebar yang berisi pemetaan nama ke alamat IP. Tiap host hanya perlu menghubungi server khusus yang menyimpan database ini bila ingin meresolve suatu nama host ke dalam alamat IP. Namun database akan selalu berubah bila host di dalam domain menggunakan sistem IP dinamis. DNS Dinamis mengatasi permasalahan ini. DNS Dinamis berfungsi sebagai perantara antara host client dengan name server. Bila client tersambung ke jaringan dengan alamat IP dinamis, maka entri nama host tersebut pada name server akan diupdate sesuai dengan alamat IP yang dimiliki host tersebut. Protokol dinamid digunakan sebagai tata cara pelaksanaan segala perubahan pada name server dan tata cara komunikasi antara server DNS Dinamis dengan client.

Judul: Process design in the production of isoeugenol and vanillin from eugenol of clove leaf oil
Abstrak: Clove leaf oil contains a high amount of eugenol (70-95%) and hence it has been considered as a potential raw material for production of isoeugenol and vanillin, which have high economic value. This study was aimed at designing production of isoeugenol and vanillin from eugenol of clove leaf oil and analyzing the potential product development financially.The specific objectives of this research work are 1) Identify the isoeugenol and vanillin, 2) Model simulation of process design of isoeugenol and vanillin, 3) Study on financial feasibility and added value. This research is expected to provide maximum economic potential of eugenol to enhance the added value of clove leaf oil. The results showed that the FTIR and NMR products confirmed that isoeugenol and vanillin present in the synthesized product were identical to the reference standards. Model simulation of process design suggested that isomerization reaction of eugenol to produce isoeugenol occurred at temperatures of 25-200oC and 1 atm pressure, with the average conversion and isoeugenol of 90% and product purity of 89,6%. Meanwhile, oxydation of isoeugenol which then produced vanillin took place at temperatures of 19.22-150oC and 1 atm pressure resulting in the average conversion of 90% and product purity of 98%. Financial analysis on isoeugenol and vanillin industries showed feasible at production capacities of 1,157,280 kg/year and 853,929 kg/year respectively, with total investment of Rp. 3,795,050,000 and 3,795,050,000 as well as working capital of Rp. 127,487,726,119 and Rp. 154,794,595,559 respectively. At an interest rate of 12% and 10 years project lifetime showed the NPV of Rp. 645,341,441,970 and Rp. 779,561,530,094 respectively. Furthermore, the IRR were 47,40% and 47,43%; net B/C ratio 3.90 and 3.91; BEP 8,178 and 5,063 products unit; PBP 1.27 and 1.25 years. Value added of eugenol to isoeugenol and vanillin industry were Rp. 145,193 and Rp 175,651/kg respectively, while labor incomes were Rp. 447.0 and Rp. 2.190/kg, processor profits Rp. 144.476 and Rp. 173.461/kg. It is concluded that designing industrial production of isoeugenol and vanillin from eugenol of clove leaf oil is financially feasible.
