Abstract

Salah satu hal yang membedakan antara laptop dengan komputer desktop adalah, pada laptop telah disediakannya media touchpad sebagai pengganti dari fungsi mouse. Touchpad mempunyai beberapa perbedaan dibanding dengan mouse. Salah satunya yaitu kemampuan touchpad yang dapat digunakan pada media yang tegak/vertical. Berbeda dengan mouse yang harus menggunakan alas yang horizontal. Perbedaan inilah yang membuat touchpad dapat dipasangkan sekalipun pada objek tegak seperti tembok, pintu, dashboard mobil, bahkan layar monitor pun dapat dipasang touchpad sehingga dapat menghemat tempat. Penelitian ini bertujuan untuk membuat touchpad yang dapat digunakan pada computer desktop melalui jalur ps2 mouse port untuk menggantikan fungsi mouse biasa. System ini menggunakan metode infrared sensing yang dipasang pada dua buah sumbu yang akan mendeteksi koordinat dari pergerakan jari si pemakai. Perancangan perangkat keras touchpad menggunakan mikrokontroler AT89C51 sebagai pusat pengendali, LED infrared dan fotodioda sebagai sensor gerak, serta push button sebagai tombol yang berfungsi sama seperti tombol pada mouse biasa.

Abstract

Perlunya pelayanan sistem informasi akademik yang cepat dan mudah pada Jurusan Teknik Elektro UNTIRTA, sehingga dirancang sebuah sistem aplikasi untuk pengaksesan informasi akademik via SMS. Sistem ini dibuat pada sebuah Personal Computer (PC) yang terhubung dengan telepon selular melalui kabel data serial dan sebuah database Microsoft Access, koneksi antara database dan Visual Basic 6.0 menggunakan komponen ADODC dan ODBC (Open Database Connectivity). ODBC digunakan untuk mengakses database relasional dan membuat program menjadi fleksibel artinya pengubahan jenis database yang dipergunakan oleh sebuah aplikasi tidak akan mempengaruhi kode program, setiap SMS yang masuk ke dalam telepon selular akan dibaca oleh sistem, kemudian dilakukan proses validasi sesuai dengan format kode yang telah ditentukan dan proses validasi NIM user. Permintaan yang dapat dilayani oleh sistem antara lain : nilai KHS, jadwal bimbingan akademik, jadwal kuliah, dan jadwal sidang skripsi.Sistem informasi akademik via SMS dibuat menggunakan Visual Basic 6.0. Untuk berkomunikasi dengan telepon selular menggunakan FBUS 1.5, program berjalan di bawah sistem operasi window XP Edition, dan sebuah telepon selular tipe Nokia 3310 sebagai sarana penerima dan pengirim SMS, sumber data diperoleh dari tabel-tabel database yang dibuat untuk keperluan sistem ini secara keseluruhan yang dapat diakses menggunakan perintah SQL (Structured Query Language). Dalam pengujian, sistem informasi akademik via SMS berhasil digunakan untuk mengirimkan permintaan pengguna dalam bentuk SMS response secara otomatis.

Abstract

Inhabitants of the Kendeng mountain region depend on the biodiversity of the forest resources for their livelihood. Mushrooms are important resource that provide benefits to mankind. The aim on this research was to document traditional knowledge in bracket fungi utilization to treat health problems in Baduy tribe community. The results described in this paper were obtained through the exploration and identification of bracket fungi as well as the interview to determine their cultural significance for Baduy people. Quantitative approaches were used to determine the Use Values (UV), Informant Consensus Factor (ICF) and Fidelity level (FL) values. A total of 6 species that were identified as bracket fungi were included to Basidiomycota. The Baduy community considers the main use of bracket fungi as a medicine for several ailments. The highest UV, ICF and FL value were obtained by Ganoderma lucidum. This study provides the information regarding bracket fungi species with the high use values that could be employed in pharmacological research and further biotechnological approaches in order to achieve an adequate revenue.

Abstract

The existence of contextual learning resources has been known to be able to improve the meaningful learning, particularly biology learning. This research provides the information about the medicinal plant utilized by the Baduy tribe as well as its endeavour in developing the results obtained as a contextual-based module. This research and development was designed using Thiagarajans’ model, which was limited in three phases (define, design, and development). The data was collected using interview guideline, validation sheets, and students' response questionnaires. The research findings inform that there were 67 species utilized by the Baduy tribe as the medicinal plants. These species belong to Spermatophyte and divided into 31 families. Furthermore, the validation results showed that the media developed was valid; in which the best component of module, based on students' response, was its presentation (the mean value was 89.5%). It can be concluded that the media developed is feasible to use as a learning resource.

Abstract

We present a Y-branch power splitter design with a multimode section using GaN on Sapphire at telecommunication wavelength. The GaN sample optical properties were also investigated, resulting in a refractive index for the GaN layers nTE=2.289±0.001 and nTM=2.324±0.00. Optimization of the structure parameters for this structure was conducted accurately using BPM methods. The results demonstrated the possibility of realizing a GaN-based Y-branch power splitter for various applications.
