Abstract

Hasil penelitian sebelumnya telah diperoleh sebanyak 40 isolat rhizobakteri yang toleran dan mampu merombak pestisida (DDT). Namun demikian dalam penelitian tersebut belum dikaji kemampuan isolat tersebut sebagai pupuk hayati (biofertilizer). Hal tersebut sangat penting untuk pengembangan inokulum yang mempunyai kemampuan ganda yaitu sebagai perombak residu pestisida (DDT) yang mencemari lahan pertanian dan lingkungan tetapi juga sekaligus sebagai biofertilzer yang mampu meningkatkan pertumbuhan dan hasil tanaman Oleh karena itu, penelitian ini bertujuan untuk mengkaji potensi isolat bekteri tersebut sebagai pupuk hayati (biofertilizer) dengan jalan menguji potensinya dalam (1) memfiksasi nitrogen, (2) menghasilkan hormon pertumbuhan IAA (Indole Acetic Acid)dan (3) sebagai dekomposer dalam merombak selulosa dan lignin.

Abstract

Penelitian dilakukan untuk mengetahui profil protein yang dibuat oleh Klebsiella sp. yang tumbuh dalam kondisi cekaman osmotik dan keasaman. Cekaman osmotik dilakukan menggunakan NaCl, sedangkan cekaman keasaman menggunakan aluminium sulfat. Klebsiella sp. ditumbuhkan dalam medium minimal yang ditambah dengan NaCl, atau aluminium sulfat, untuk menimbulkan efek cekaman tunggal, atau menggunakan kedua senyawa tersebut untuk menghasilkan efek cekaman ganda. Protein total yang diekstrak dari sel kemudian dielektroforesis pada SDS-PAGE 12%. Hasil analisis menunjukkan beberapa protein intraselular, protein membran, atau protein ekstraselular yang dibuat dalam kondisi cekaman spesifik. Dalam kondisi cekaman osmotik, dibuat protein intraselular berukuran 42,7 kDa, dan protein membran berukuran 53,3 kDa. Pada cekaman asam dihasilkan protein intraselular berukuran 54,7 kDa, 25,3 kDa, 14,2 kDa, dan satu protein membran berukuran 43,9 kDa, serta protein ekstraselular berukuran 17–29 kDa. Dalam kondisi cekaman ganda, terdeteksi satu protein intraselular spesifik berukuran 26,7 kDa dan satu protein membran berukuran 61,1 kDa. Dalam cekaman osmotik, diketahui terdapat korelasi positif, sedangkan dalam cekaman ganda terdapat korelasi negatif terhadap macam protein. Dalam cekaman keasaman, tidak diperoleh pola korelasi yang spesifik.

PT. X is one of the 29 (twenty nine) oil palm plantations managed by PT. XY which is engaged in the agro-industry business. Assets are an important part of a company, so their management must also be appropriate. In managing the fixed assets contained in PT. X has been computerized using Microsoft Excel in the process of managing fixed asset data, but as a data processing tool Microsoft Excel has problems in presenting fixed asset reports which are quite time-consuming and inefficient, annual depreciation calculations must be inputted periodically, lots of fixed asset data in the form of transactions, monitoring, depreciation and procurement which are likely to be scattered and not well organized. The design of a web-based fixed asset management information system uses the waterfall method which has several stages, namely: system analysis, system design, program coding, program testing, system implementation and system maintenance. Testing this website is in the form of a black box test. The result of this design is a fixed asset management information system for PT. X web-based by using the straight line method (Straight Line method) on depreciation of fixed assets. Then the results of testing the menu on the website go well as it should so it is expected that the website can be useful for PT. X and employees who work at PT. X.

Abstract

The presence of employees is an important aspect of a company. Therefore, the employee recruitment process must be carried out professionally and carefully to ensure that the selected employees can make a meaningful contribution to the company. If the recruitment process is carried out subjectively and conventionally, the company may face difficulties in making the right decisions regarding employee recruitment. If this continues over a long period of time, it can have a negative impact on company performance and hinder the achievement of goals. To obtain prospective employees who are competent and in accordance with the required classification, employee recruitment requires appropriate selection. The aim of this research is to build a decision support system in employee recruitment so that it can help companies in determining the right employee candidates. To ensure objectivity in the employee recruitment process, it is necessary to use appropriate and appropriate methods in employee recruitment. The methods used in this research are Rank Order Centroid (ROC) and Multi-Attributive Border Approximation Area Comparison (MABAC). In the employee recruitment process, four criteria are used, namely honesty, presence, attitude and skills. The results of the decision support system using the ROC and MABAC methods are getting a ranking of prospective employees so that they become the best recommendations in the employee recruitment process
