Abstract

Konsep wisata kampung akhir-akhir ini mulai diminati. Wisata tersebut mengemas pemandangan alam dan kegiatan masyarakat di suatu wilayah sebagai obyek yang dijual baik untuk relaksasi maupun sebagai kemasan pendidikan. Pada konsep tersebut, wisatawan dapat mengikuti sebuah route yang disusun mengitari beberapa kampung dan pinggiran hutan sambil melihat kegiatan masyarakat di area tersebut. Wisatawan dapat berhenti atau bahkan menginap di pemukiman penduduk untuk merasakan sensasi sebagai orang kampung. Tahura Nuraksa, terletak di kawasan Taman Hutan Raya Nuraksa yang terletak di dusun Kumbi, desa Pakuan, Lombok Barat, sangat berpotensi untuk dikelola menjadi salah satu kampung wisata di Lombok seperti yang diuraikan pada paragraf pertama. Ia memiliki air terjun, goa, pura, danau, hutan, dan juga camping ground. Camping ground ini sering digunakan untuk kegiatan outbond dan perkemahan. Juga terdapat area memanah, flying fox, dan kolam renang anak-anak. Salah satu spot yang menarik di kawasan tersebut adalah air terjun Segenter. Namun area tersebut belum tersentuh jaringan komunikasi. Sementara itu, untuk memenuhi kebutuhan wisatawan terutama untuk berkomunikasi dan update status, jaringan nirkabel merupakan fasilitas utama bagi wisatawan dengan konsep tersebut. Oleh sebab itu, kegiatan pengabdian ini memasang sebuah penguat sinyal GSM pada jalur menuju air terjun tersebut. Saat ini, komunikasi telah dapat dilakukan di area menuju air terjun menggunakan beberapa provider GSM. Permasalahan yang belum berhasil ditangani adalah kelemahan sinyal ketika cuaca mendung.

Abstract

To diagnose asthma attack we use Weighted Product and TOPSIS method to analyze the data. The lack of Weighted Product for the expert system is there are no cost and benefit for the criteria. We use combined it with TOPSIS to determining an alternative preference based on the ideal positive and ideal negative solution. WP methods have advantages where it has an initial weight which is TOPSIS don’t have. Combining the two methods aims to determine the effectiveness of the method. We use 40 data test on two different experts and compare it with our proposed method in this research. The result shows that, for the first expert, we gain accuracy for Weighted Product, TOPSIS and combined of WP and TOPSIS are 12,5%, 12,5%, and 60% respectively and for the second expert, we gain 30%, 30%, and 70%. Its show that the combined methods are better used compared to the WP and TOPSIS methods.

Abstract

License plates are a unique feature to identify a vehicle in the combination between letters and numbers. Feature extraction needed to identify each letter and number in a digital image. There are several methods in feature extraction, one of them uses a gradient feature extraction. In this research, an application program to identify the license plate is a character gradient method and backpropagation neural network (BNN). First, the digital image is cropped to get a license plate then segmented to generate each character. The next step is the extraction feature using Character gradient to get a particular feature from each character. Backpropagation neural networks are used as data classification. This research consist of two types of testing: performance analysis based on hidden layers and feature quantity in training datasets and license plate data. From the result, we can conclude that the quantity of features affects the system performance. The highest performance rate in the first scenario test is feature 48 with 60 hidden layers, and in the second scenario, the highest is feature 108 with 60 hidden layers. The lowest performance rate is shown in feature 12 with 20 hidden layers. Keywords: License plate, character gradient method, backpropagation neural network, feature, hidden layer.
