Isoprophylamine merupakan produk dengan komoditas yang diminati oleh industri pertanian di Indonesia. Perkembangan industri isopropylamine sejalan dengan kemajuan dalam bidang pertanian khususnya dalam bidang pemberantasan hama (herbisida, insectisida, bakterisida). Pengguanaan utama isopropylamin adalah dalam bidang pertanian yaitu sebagai bahan baku pada industri pembuatan herbisida dan insectisida. Disamping digunakan dalam bidang pertanian isopropylamin juga digunakan dalam Industri tekstil digunakan sebagai adiktif pada bahan pencelup atau pewarna dan juga sebagai bahan adiktif pada proses pembuatan tekstil yang memiliki sifat khusus. Metode produksi Isopropilamine dicirikan dalam reaktor fixed bed. Molibdenum (Mo) dan/atau wolfram (W) ditambahkan ke dalam katalis berbasis Ni, didalam reaktor memuat katalis berbasis nikel berbentuk bulat di dekat ujung masuk, dekat ujung keluar berbentuk batang pengisi katalis berbasis nikel. Reaksi terjadi pada reaktor fixed bed dengan suhu 125°C, tekanan 15 atm. Kemudian dimurnikan dengan proses destilasi yang berfungsi untuk memisahkan produk bawah dan produk atas. Produk atas akan mendapatkan produk utama yaitu monoisopropylamine dengan konversi sebesar 99,3%.

Full text linkPT Unibless Indo Multi is engaged in IT Services, IT Trading, and IT Outsourcing. In this paper focuses on IT Trading, which includes the sale and rental of IT hardware, the provision of office equipment, the provision of shelves and archival support equipment and others. The author finds problems that occur specifically in the inventory of goods in processing inventory data still using simple applications, which causes the company's performance to be less than optimal. The author aims to solve existing problems by designing and building an inventory data management system using visual basic with the waterfall method, Unified Modeling Language (UML), Balsamiq Mockup and using a Microsoft Access database. Based on the test results using blackbox testing, the system runs as expected. After testing, 92.5 out of 7 respondents agreed that the system is easy to understand and use

PEMANFAATAN KITOSAN DARI CANGKANG RAJUNGAN SEBAGAI BIOKOAGULAN PADA AIR LIMBAH INDUSTRI TAHU
Full text linkCangkang rajungan memiliki kandungan kitin yang banyak yaitu 22,66%. Kitin akan diproses menjadi biokoagulan yang akan mengurangi kandungan COD(Chemical Oxygen Demand) pada limbah produksi tahu. Limbah produksi tahu masih mengandung konsentrasi COD (Chemical Oxygen Demand) sebesar 1017,35 mg/L yang dapat mencemari lingkungan pabrik. Penambahan biokoagulan dengan proses koagulasi dan flokulasi diharapkan mampu menurunkan kadar COD (Chemical Oxygen Demand). Penelitian ini bertujuan untuk mengetahui penambahan dosis terbaik pada sampel limbah dalam pembuatan biokoagulan. Proses penelitian dilakukan secara bertahap dimulai dengan pengeringan dan penghalusan cangkang rajungan yang kemudian dilanjutkan dengan proses demineralisasi, deproteinasi, dan deasetilasi. Pada tahap selanjutnya biokoagulan ditambahkan pada limbah dengan skala laboratorium menggunakan metode koagulasi dan flokulasi. Proses koagulasi dan flokulasi perlu ditambahkan biokoagulan untuk menghilangkan bahan pencemar yang tersuspensi dengan bentuk koloid dalam air. Hasil penelitian menunjukkan bahwa penambahan biokoagulan 0,4g:250ml mempunyai effisiensi terbaik yaitu sebesar 99,5% yang dapat menurunkan kadar COD sebesar 1017,35 mg/l. Biokoagulan dapat menurunkan kadar COD (Chemical Oxygen Demand) sesuai baku mutu yang telah ditetapkan menjadi 4,893 mg/L sehingga tidak mencemari lingkungan

A survey design for integrated monitoring of salmonids
Full text linkThe Oregon Department of Fish and Wildlife conducts three large-scale projects to monitor coastal salmonids. The Coastal Salmonid Inventory Project conducts spawning surveys for returning adults, the Early Life History Project monitors juvenile salmonids, and the Aquatic Inventory Project monitors stream habitat. In 1998, an integrated monitoring design was initiated to facilitate the integration of data among these projects. A rotating panel design utilizing the Environmental Protection Agency's Environmental Monitoring and Assessment Program (EMAP) site selection process was deemed to be the best approach to meet the needs of the studies. EMAP utilizes a Geographic Information System (GIS) to draw a spatially balanced sample of a population. The program provides forced overlap between projects where their sampling domains overlap, and facilitates sampling intensification. The rotating panel design balances the utility of trend detection through repeated sampling at the same sites over time, with the advantages of extensive sampling of the target populations. Arc Info was used to create coverages of the population of streams to be sampled for each project. EMAP selects a spatially balanced sample from a coverage, forces overlap of sites for each project where their sampling extents coincide, associates each point with a stream reach, and measures the distance upstream from the reach origin. This plan was successfully implemented during the 1998 field season.Julie C. Firman and Steven E.

The Effect of Caffeine on Performance
Full text linkThe purpose of this study was to investigate the effects of caffeine on reaction time, as measured by PEBL2 software. To test this relationship, participants were measured across three tests within the PEBL2 software, with one group of participants receiving a 300 mL dose of caffeinated coffee before testing, and another receiving a 300 mL dose of a decaffeinated coffee. It was hypothesized that the participants who received a dose of caffeinated coffee would perform better and thus have faster reaction times than those who received the decaffeinated control. The results did not support the hypothesis: the mean response time was the same across the caffeinated and decaffeinated conditions. The results of this study are discussed in relation to other findings on the effects of caffeine on performance, specifically the relationship between caffeine and reaction time
