Abstract

Species of entomopathogenic fungi, i.e. Metarhizium anisopliae (Metsch.) Sorokin, Metarhizium brunneum Petch, Beauveria bassiana (Bals.) Vuillemin, Fusarium oxysporum Link and Aspergillus flavus Link were tested their effectiveness as bio-control against to subterranean termite Coptotermes gestroi Wasmann. Pure culture of each fungal species was stored in 40C. Before used, those fungi were recultured in Sabouraud Dextrose Agar with Yeast Extract (SDAY) media and incubated in 240C and RH 95% for 3 weeks. The series of conidial density has been used (0, 107, 5x106, 106, 5x105 and 105 conidia/ml) for pathogenicity test. The LC95 of M. brunneum was used for contact and baiting methods and the bioassay was repeated four times. The data was analyzed using ANOVA and with DNMRT. The lethal concentration (LC) and lethal time (LT) were calculated using probit analysis. The results revealed that increase of conidial density of each fungi species caused more mortality of C. gestroi. All fungi species could cause mortality of C. gestroi more than 80% even with the density of 5x106 conidia/ml, however M. brunneum could causing mortality more than 80% at density of conidia as low as 5x105 conidia/ml. Based on the probit analysis, the value of LC50 and LT50 with contact method were calculated at 1.8 x 105 conidia/ml and 2.01 (1.52 ~ 2.40) days respectively.

Abstract

Sekolah Tinggi Teknologi Dumai merupakan sebuah instansi yang bergerak dibidang pendidikan yang memiliki banyak mahasiswa dari berbagai daerah. Mahasiswa setiap tahun nya diwajibkan membayar uang kuliah. Namun, bagian keuangan saat ini masih menginput data-data pembayaran uang kuliah mahasiswa menggunakan Microsoft Excel, dengan membuat nominal dan jenis pembayaran uang kuliah di dalam file dan di simpan secara pisah berdasarkan tahun ajaran, sehingga saat akan membuat rekapan bagian keuangan membutuhkan waktu yang cukup lama karena harus membuka file satu per satu. Dari permasalah tersebut penulis membuat aplikasi manajemen keuangan berbasis Whatsapp API. Pembuatan aplikasi menggunakan bahasa pemrograman PHP dan juga menggunakan Whatsapp API sebagai notifikasi bahwa pembayaran telah selesai dilakukan. Hasil pengujian aplikasi bahwa aplikasi tersebut dapat memudahkan bagian keuangan dalam memanajemen pembayaran uang kuliah, dalam pembuatan rekapan pembayaran mahasiswa, hanya dengan membuat NIM mahasiswa maka rekapan pembayaran sudah bisa dicetak.

Abstract

College X in Dumai City always strives to continuously improve internal quality so that it can compete with other universities. One effort to improve quality is by assessing lecturer performance every year. So far, the process of selecting outstanding lecturers or favorite lecturers is still based on the subjectivity of those who choose, so there is a lack of transparency in the selection process. This research discusses the application of the Simple Additive Weighting (SAW) method in a decision support system for selecting favorite lecturers at College X, Dumai. Lecturer performance assessment is based on criteria such as discipline, achievement, behavior, responsibility and communication, involving students as respondents. Data was collected through literature studies, interviews, observations and Likert scale-based questionnaires. The calculation process using the SAW method includes normalization of the decision matrix and ranking based on criteria weights. The research results show that the SAW method provides objective, transparent and systematic results in selecting favorite lecturers. The system developed is able to support universities in improving the quality of lecturers through more structured feedback.
