Abstract

Pada kurun 1975-2010 Pemerintah Kabupaten Tasikmalaya telah melakukan pembangunan pariwisata di Kampung Naga dengan tujuan meningkatkan kehidupan ekonomi masyarakatnya. Namun, masyarakat Kampung Naga melakukan respons negatif terhadap pembangunan tersebut. Mengapa masyarakat Kampung Naga melakukan respons negatif terhadap pembangunan pariwisata, padahal pembangunan tersebut dapat meningkatkan kehidupan ekonominya? Tujuan studi ini adalah untuk mendeskripsikan bentuk respons masyarakat Kampung Naga terhadap pembangunan pariwisata dan memahami penyebab munculnya respons itu. Metode penelitian yang digunakan adalah metode sejarah yang terdiri atas heuristik, kritik, interpretasi, dan historiografi. Pengumpulan datanya dilakukan dengan studi kepustakaan dan wawancara sejarah lisan. Teknik analisis datanya menggunakan model interaktif. Hasilnya menunjukkan bahwa bentuk respons negatif masyarakat Kampung Naga terhadap pembangunan pariwisata terjadi secara bertahap dari skala lokal sampai skala nasional. Respons negatif tersebut disebabkan adanya perbedaan pemaknaan terhadap konsep pariwisata. Bagi masyarakat Kampung Naga, pariwisata bermakna silaturahmi yang bertujuan mempererat persaudaraan, sedangkan bagi pemerintah adalah aset untuk mendapatkan keuntungan finansial. In the period 1975-2010 Tasikmalaya Regency Government has made tourism development in Kampung Naga. The purpose was to improve the economic life of Kampung Naga community. However, the Kampung Naga community responded negatively to that development. Why did the Kampung Naga community respond negatively to the development of tourism, whereas that development could improve the life of its economist? The purpose of this study is to describe the response form of Kampung Naga community to the tourism development and to understand the cause of the response. The research method used is a historical method, namely heuristics, criticism, interpretation, and historiography. Collecting data are using literature studiies and oral history interviews. Interactive model is used to analyze data. The result of this study shows that the negative response form of Kampung Naga community toward tourism development happened gradually from local scale to national scale. The response was caused by the difference of the meaning to the concept of tourism. For the community of Kampung Naga, tourism means a relationship that aims to strengthen the brotherhood, while for the government assets to improve financial benefit.

Abstract

One type of unmanned aircraft that is often used today is quadrotor. This type of aircraft has the ability to take off vertically. This study implemented an altitude control system on the z-axis quadrotor. The control used is the full state method of Linear Quadratic Regulator (LQR) with artificial neural networks. The LQR full state feedback method used in this system is 12-states with each feedback constant Ktuned to the neural network method. This study implements the artificial neural network method to change the feedback constant on the z-axis. Artificial neural network architecture used 12 input layers, 48 hidden layers, and 1 output layer. This study compares the value of the results of the simulation with the response value of the system implementation results applied to the quadrotor. Testing with full state LQR feedback using artificial neural networks improves the system response to ±0.77 seconds and improves steady state error values up to ±12 cm. Based on the results of these studies, this system can be implemented to control other systems.

Abstract

This paper presents a new rules-based of a real-time decision system for an autonomous wheeled robot with the holonomic-drive system. The robot uses decisions to avoid collisions with obstacles. The decision rules based on Grid-Edge-Depth Map. The Grid-Edge-Depth map represents the obstacle’s position and distance in the environment. The generation process of the Grid-Edge-Depth map presented in previous research. The decisions of the first scenario with no destination point are forward, stop, 90o right turn, and 90o left turn. The decisions of the second, and third scenarios with a destination point are forward, stop, 90o right turn, 90o left turn, 45o forward to the right, 45o forward to the left, slide to the right, and slide to the left. The proposal tested in a 5x3 metre living environment. Finally, the experiment resulted in 93.3% of navigation’s success for all the scenarios.

Abstract

Kendali otomatis dibutuhkan oleh kapal katamaran tanpa awak dalam menavigasi menuju arah tertentu dan dapat menangani gangguan serta perubahan kondisi dengan efektif dan optimal. Kendali PID cocok untuk pengendalian kapal, namun mempunyai kelemahan dalam pencarian gain PID optimal untuk setiap kondisi. Fuzzy mampu menangani penjadawalan gain PID untuk setiap kondisi dan neural network mampu mengoptimasi desain fuzzy, sehinggadilakukan penggabungan menjadi kendali adaptif neuro fuzzy PID (N-F PID). N-F PID merupakan kendali PID dengan penjadawalan gain PID (Kp, Ki dan Kd) yang dinamis berdasarkan besarnya nilai error dan delta error oleh neuro fuzzy. Neuro fuzzy yang digunakan adalah adaptif neuro fuzzy inference system (ANFIS). ANFIS mampu melakukan pembelajaran dengan training data baru untuk memperbaiki performa. Training data baru didapatkan dari proses tuning dengan mengalikan output masing-masing fuzzy yang belum terlatih dengan konstanta tertentu hingga didapatkan settling time cepat dan persentase overshoot maksimum kecil.Simulasi N-F PID dengan Matlab dan ekperimen kapal katamaran menunjukkan N-F PID mempunyai performa yang lebih baik dari pada kendali fuzzy PID dan kendali PID, dilihat dari settling time dan persentase overshoot maksimum. N-F PID mempunyai tingkat presisi pengendalian yang lebih rendah daripada kendali fuzzy PID dan PID berdasarkan data eksperimen.

Abstract

Previous studies have used financial ratios extensively to build their predictive model of financial distress. The Altman ratio is the most often used to predict, especially in academic studies. However, the Altman ratio is highly dependent on the validity of the data in financial statements, so other variables are needed to assess the possibility of manipulation of financial statements. None of the previous studies combined the five Altman Ratios with the Beneish M-Score. We use Stacking Ensemble Learning to classify crisis companies and perform a comprehensive analysis. This insight helps the investment public make lending decisions by mixing all the financial indicator information and assessing it carefully based on long-term and short-term conditions and possible manipulation of financial statements.

Abstract

Virtual Reality (VR) technology in tourism is a rapidly growing product of collaboration between technology and tourism. The benefits of VR during the Covid-19 pandemic allow the technology to survive. However, previously, VR had already seen usage in various profitable aspects of tourism. For that reason, it is important to examine how VR affects an individual’s—among Indonesian millennials—interest in visiting travel destinations. This study aims to analyze the effects of using VR by observing the content quality, system quality, presence, enjoyment and satisfaction in motivating visits among millennials. A total of 371 samples were collected in this study, obtained from respondents via online-distributed questionnaires. The data were processed using the structural equation modeling (SEM) method. The results indicated that out of seven hypotheses proposed, six were accepted and one was rejected. Content quality and system quality affected satisfaction, while presence affected enjoyment and satisfaction; satisfaction and enjoyment affected intention to visit. Enjoyment does not affect satisfaction. This study also shows that content quality, system quality, presence, enjoyment indirectly affect millennials’ interest to visit travel destinations. The quality of the VR system played an important role in creating satisfaction and intention to visit among millennials, so travel destination managers need to consider this.

Abstract

Sustainable Tourism Development (STD) consists of three dimensions known as environment, economic and social. Although these three dimensions influence each other and cannot stand on their own, and are assumed to be supportive to each other and compatible. However, most studies focus on the environmental and economic dimensions. The social dimension gains less attention and is difficult to attain and operationalize. In order to implement a balanced and successful STD, it needs to be supported by all the tourism stakeholder, including the tourist itself. Therefore, it is necessary to explore the social dimension of STDs and also tourist behavior regarding their social conscious. However, the discussions and understanding of social dimension in STD and socially conscious behavior are still limited. This study aims to define a clear understanding and definition of social dimension of STD which in this study is referred as social sustainability and also a socially conscious tourist. Starting with exploring the aspect of social dimensions formulation and exploring clear definitions of social dimensions of STD's and socially conscious tourist. This study is an exploratory study that aims to explore the boundaries of social dimension of STD and to develop a construct of socially responsible tourist. This study is a qualitative approaches, which includes systematic literature review and Delphi method to obtain expert judgment to gather social dimension aspects of sustainable development, especially in STD. The results of this study are social dimension’s aspects of STD, an understanding of social sustainability and socially conscious tourist in STD.

Abstract

Budaya merupakan unsur signifikan kepariwisataan. Wisatawan melakukan perjalanan ke berbagai tempat karena orintasi budaya. Survei UNWTO (United Nations World Tourism Organization) setiap tahunnya, melaporkan perkembangan pariwisata budaya terus meningkat. NESPARNAS (Neraca Satelit Pariwisata Nasinoal) juga merekam pendapatan devisa yang tinggi dari segmen pariwisata budaya. Gambaran itu memberikan sinyalemen potensi aset budaya dapat dikembangkan sebagai pesona pariwisata berbasis konservasi dan ekonomi. Namun, beberapa wilayah di Indonesia belum mampu memanfaatkannya secara produktif, Lombok Timur, di Nusa Tenggara Barat, mengalami kemandekan semacam itu. Tujuan penelitian ini melakukan identifikasi dan analisis potensi aset budaya Kabupaten Lombok Timur menjadi pesona pariwisata. Selanjutnya, melakukan evaluasi tingkat daya tarik pasar dan daya tahan aset budaya. Melalui pertimbangan praktis, penelitian ini membatasi diri pada aset budaya fisik. Lima aset budaya terpilih; Bale Beleq Sembalun, Bale Balaq Tanjung Luar, Bale Beleq Jerowaru, Rumah Adat Limbungan, dan Makam Selaparang. Metode analisis data menggunakan model audit Matrik Daya Tarik Pasar dan Daya Tahan Aset Budaya. Penelitian ini menemukan lima aset budaya berada pada tiga klaster; A1, A2, dan C2. Rumah Adat Limbungan dan Makam Selaparang pada klaster A1, memiliki daya tarik pasar dan daya tahan aset budaya yang Tinggi. Bale Beleq Sembalun pada klaster A2, memiliki daya tarik pasar yang Tinggi dengan daya tahan aset yang Sedang dan Bale Balaq Tanjung Luar dan Bale Beleq Jerowaru berada pada klaster C2, memiliki daya tarik pasar dan daya tahan aset yang Sedang.
