Judul: The Effectiveness of Instagram and Website as  Promotional Media for Community-Based Ecotourism in Gunung Ciremai  National Park
Abstrak: Ekowisata berbasis masyarakat (EBM) sebagai tren baru pariwisata memiliki dua tantangan dalam pengomunikasiannya, yaitu masyarakat belum terinformasikan dan program pengomunikasian belum baik. Taman Nasional Gunung Ciremai (TNGC) sebagai kawasan ekowisata berbasis masyarakat tidak hanya mempromosikan kawasannya secara konvensional, tetapi juga melalui Instagram dan website. Sehingga, tujuan dari penelitian ini yaitu menganalisis efektivitas Instagram dan website sebagai media promosi TNGC. Metode yang digunakan adalah metode kuantitatif didukung dengan data kualitatif. Responden merupakan khalayak Instagram dan website TNGC yang diperoleh melalui accidental sampling. Berdasarkan penelitian, website merupakan media yang paling efektif untuk melakukan promosi dibanding Instagram. Faktor yang berhubungan efektivitas Instagram pada indikator perhatian adalah kelengkapan, kejelasan, dan daya tarik pesan. Sementara itu pada indikator ketertarikan berhubungan dengan kejelasan pesan, indikator keinginan berhubungan dengan kelengkapan, daya tarik, dan frekuensi pesan, indikator tindakan berhubungan dengan kejelasan dan frekuensi pesan. Sementara itu kelengkapan pesan, kejelasan pesan, desain website, dan frekuensi pesan website berhubungan dengan efektivitas website., Community-based ecotourism (CBE) as a new trend of tourism has two challenges in communicating, namely the community has not been informed and the communication program has not been good. Mount Ciremai National Park (TNGC) as an CBE area does not only promote its area conventionally, but also through Instagram and websites. Thus, the purpose of this study is to analyze the effectiveness of Instagram and the website as a promotional medium for TNGC. The method used is a quantitative method supported by qualitative data. Respondents are the audience of Instagram and the TNGC website obtained through accidental sampling. Based on research, the website is the most effective media for promotion compared to Instagram. Factors of the messages related to the effectiveness of Instagram on attention indicators are completeness, clarity, and attractiveness. Meanwhile, the interest indicator relates to clarity, the desire indicator relates to the completeness, attractiveness, and frequency, the action indicator relates to the clarity and frequency. Meanwhile, completeness, clarity, website design, and website frequency are related to website effectiveness.

Judul: Hubungan media promosi dengan keberhasilan ekowisata Taman Nasional Ujung Kulon
Abstrak: Ekowisata merupakan suatu konsep pariwisata yang mencerminkan wawasan lingkungan dan kelestarian lingkungan. Media promosi yang dapat digunakan untuk mempromosikan ekowisata adalah Website, facebook, twitter, google, poster, brosur, roll up banner dan lainnya.Tujuan penelitian ini adalah untuk menganalisis pentingnya media promosi terhadap perkembangan ekowisata TNUK (Taman Nasional Ujung Kulon). Penelitian ini menggunakan metode survey dengan jumlah responden 50 pengunjung. Penentuan responden dalam penelitian ini dengan menggunakan teknik accidental sampling. Hasil menunjukkan bahwa keberhasilan ekowisata TNUK berhubungan nyata dengan pesan media promosi pada aspek attention, interest dan desire, sedangkan pada aspek action tidak berhubungan nyata. Kekuatan pesan media promosi leaflet yang berhubungan nyata adalah aspek interest, desire, dan action, sedangkan aspek attention tidak berhubungan nyata. Kekuatan pesan media promosi facebook yang berhubungan nyata hanya pada aspek action. Kekuatan pesan media promosi poster yang berhubungan nyata dengan keberhasilan ekowisata TNUK adalah pada aspek attention dan interest, sedangkan pada aspek desire dan action tidak berhubungan nyata., Ecotourism is a concept that reflects the insights of environmental tourism and environmental sustainability. Media campaigns that can be used to promote ecotourism is website, facebook, twitter, google, adwords, posters, flyers, roll up banners, direct mail, t-shirts, hats, key chains, and pins. The purpose of this study was to analyze the importance of the media campaign against the development of ecotourism Ujung Kulon National Park. This study used a survey method with the number of respondents 50 visitors ecotourism UKNP (Ujung Kulon National Park). Determination of the respondents in this study by using accidental sampling technique.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
