Abstract

Linear equation of QSAR model of insecticidal activity of carbamate derivatives based on atomic charge and hydrofobic, electronic and steric descriptors has been investigated. The descriptors were calculated by semiempirical PM3 method and biological activities of the compound were taken from experiment. The relationship between descriptors and their biological activities was analyzed with multilinear regression analysis.The best linier equation resulted from that analysis is : Log 1/LD 50 = 12,651 + (2,467 qC2) + (2,832 qC4) - (14,089 qC6) - (0,24 qO7) + (0,293 μ) - (0,08 SA (grid)) +(0,041 V)+ (0,141 EH) - (0,303 log P) n = 39 ; r = 0,839 ; adjusted r2 = 0,612 ; SE = 0,355; Fhit/Ftable = 3,443 PRESS=5,188 Based on that model, a new carbamate derivative has been designed which show better predicted activity (log 1/LD50 = 9,79) while the old one (log 1/LD50 = 8,81). This new carbamate insecticide derivative can be synthesized laboratoriccally for the next prove. Key Word:QSAR, Insecticides carbamate, PM3.

Abstract

This research is aimed to determine the level of vitamin C in the mango Gadung which stored as long as 0 days; 1 day; 2 days; and 3 days. It is used iodimetric titration. Standard iodine solution used as titrant while starch as the indicator. Determination of raw normality iodine standardization carried out by titration of iodine with sodium thiosulphate solution primer. Normality primary sodium thiosulphate solution (0.0125 N) are determined through standardized sodium thiosulphate with potassium dichromate. Levels of vitamin C in the fruit is determined by linear regression analysis were made based on the graph of the vitamin C levels versus volume of iodine standard solution which used in the titration. The curve gives the equation as following: y = 413.8 x – 1.238. Levels of vitamin C of mango Gadung which has varied retention time as follows: 0.26% (0 days); 0.22% (1 day); 0.20% (2 days); and 0.16% (3 days).

Abstract

Sistem kendali perangkat listrik terutama lampu pada saat ini masih menggunakan kaedah konvensional yaitu masih menggunakan saklar sebagai antarmuka sistem. Teknologi remote merupakan teknologi untuk mempermudah pengguna untuk mengeksekusi perangkat elektronik secara jarak jauh. Akan tetapi teknologi remote yang digunakan saat ini rata-rata masih menggunakan teknologi inframerah. Teknologi inframerah mempunyai beberapa keterbatasan dalam mengirimkan sinyalnya yaitu arah transmisi dan jarak. Berbeda dengan sistem tranmisi radio frekuensi yang dapat dicapai dari segala arah dan mempunyai jarak trasnmisi yang jauh. Dalam tujuan penelitian adalah membangun sistem kendali jarak jauh perangkat listrik terutama lampu menggunakan teknologi radio frekuensi. Sistem dibangun dalam dua sistem yaitu sistem pemancar dan sistem penerima berbasis mikrokontroler dan modul radio frekuensi. Metodelogi pengembangannya dimulai dengan analisa sistem, perancangan alat, pembuatan algoritma program, pengkodean dan pengujian sistem. Penelitian ini menghasilkan prototipe sistem kendali perangkat listrik wireless berbasis Radio Frekuensi.

Abstract

Dalam pengembangan sistem informasi, kemungkinan kesalahan atau kegagalan (failure) cukup tinggi dan acap kali terjadi kasus kegagalan yang berulang yang dapat berakibat fatal bagi kelangsungan transaksi sistem pada suatu organisasi, sehingga penting untuk melakukan antisipasi untuk mengatasi kegagalan (failure) atau meminimalisir resiko kegagalan pengembangan sistem informasi tersebut. Pada penelitian ini dikaji beberapa kesalahan-kesalahan yang umum dan sering terjadi pada saat pengembangan sistem informasi menggunakan pendekatan forward chaining. Berdasarkan pada proses penelitian yang telah dilakukan, pendekatan metode penalaran kedepan (forward chaining) dapat digunakan dalam membentuk suatu aturan yang dapat melakukan penalaran terhadap pengetahuan kegagalan pengembangan sistem informasi dan setiap aturan yang dimasukkan ke dalam basis pengetahuan mampu di baca (dirunut) dengan baik oleh sistem.

Abstract

Salah satu upaya yang dapat dilakukan untuk mengolah limbah cair kelapa sawit adalah menggunakan nanokomposit karbon aktif/TiO2 dengan metode adsorbsi-fotodegradasi. Metode adsorbsi-fotodegradasi didasarkan pada proses adsorbsi senyawa organik oleh permukaan padatan yang sekaligus mampu mendegradasi senyawa organik. Pada penelitian ini bertujuan untuk menguji kinerja nanokomposit karbon aktif/TiO2 dalam mendegradasi limbah cair kelapa sawit. Karbon aktif/ TiO2 hasil sintesis dikarakterisasi menggunakan spektrofotometer XRD dan SEM kemudian dilanjutkan pengujian aktivitas fotodegradasi dari sampel karbon aktif/ TiO2 dibawah sinar matahari dengan parameter nilai BOD. Hasil difraktogram sinar-X menunjukkan bahwa nanopartikel TiO2 memiliki ukuran kristalit sebesar 79,6 nm sehingga dapat diasumsikan bahwa partikel tersebut bersifat single kristal. Analisis foto SEM memperlihatkan morfologi partikel TiO2 berupa gumpalan putih yang tersebar tidak merata dipermukaan karbon aktif yang berbentuk batangan berpori dengan ukuran yang tidak seragam. Hasil pengujian aktivitas fotodegradasi menunjukkan bahwa nanokomposit karbon aktif/ TiO2 mampu menurunkan nilai BOD dari limbah cair kelapa sawit melalui mekanisme adsorbsi-fotodegradasi. Nilai BOD dari sampel karbon aktif/ TiO2 secara berurutan adalah sebagai berikut Sampel A (45,30 mg/L); Sampel B (67,65 mg/L), Sampel C (22,95 mg/L), Sampel D (22,95 mg/L) dan Sampel E (0,60 mg/L).

Abstract

Human resource factor is a mainly asset in the enterprise, because it has a unique characteristic and will not easy to imitated by the competitor. To make a well management of human resource process and its development in the enterprise is important. Together with the coming of information era, then the utilization of information technology to manage and develop the human resource is really necessary. Its means the human resources which managed traditionally would be change by manage it electronically. In the other word, the term of human resource management (HRM) changed by electronic human resource management (e-HRM). Certainly, to develop and manage e-HRM continuously is not easy without the consideration of such factors that exist within it as: human, organization, communication, and technology factors. Therefore, in this article explained such factor that will encourage these four factors in e-HRM practice, with the result is the e-HRM well management, and finally will increase the human resource development in the enterprise. After the consideration of human, organization, communication and technology factor, then continue by analyzed ten of social theory and used it to encourage the e-HRM development perfectly, where the utilization of each social theory is adjusted with appropriate factor only. The social theories that used in this article are: 1) Attribution theory, 2) Act* theory, 3) Argumentation theory, 4) Contagion theory, 5) Cognitive dissonance theory, 6) Agenda setting theory, 7) Absorptive capacity theory, 8) Actor network theory, 9) Adaptive structuration theory, and 10) Administrative behavior theory. Furthermore, the last part of this article is an explanation of human, organization, ommunication, and technology factor, and how to make each factor will give an effective function in e-HRM practice by using the social theory style in order the development of e-HRM more effective, efficient, and increase continuously.

Abstract

Radicals produced naturally in the body, can cause various diseases when present in large quantities. High levels of free radical compounds showed low antioxidant activity that leads to degeneration of the body cells, metabolic disorder, decreased immune response that trigger the emergence of a variety of degenerative diseases. Need extra antioxidants from outside the body in order to help prevent the adverse effects of free radicals, such as antioxidants derived from plants used as cooking ingredients or food ingredients. There are some herbal plants that are a source of natural antioxidants , which are also used as a spice, such as turmeric (Curcuma domestica), ginger (Zingiber offcinale), nutmeg (Myristica fragrans), paprika (Capsicum annum), lemongrass (Cymbopogon citratus), galangal (Alpinia galangal), onion (Allium cepa) and garlic (Allium sativum).
