During one year of operation, the number of tourist visits has decreased since July 2023, decreasing by 6.200 tourists or 44,58% compared to the previous month. This has an impact on the decline in income levels for the management, business units and labor in the tourist area. Based on the description, the objectives of this study are (1) Identifying factors that influence tourism demand and estimating the economic value of KUA tourism objects. (2) Estimating the economic impact caused by tourism activities around KUA tourism objects. (3) Formulating strategies for developing tourism activities in KUA tourism objects. The methods used in this research are Individual Travel Cost Method (ITCM), Multiplier effect, and SWOT-ISM. The results of this study are: (1) Factors that influence the demand function of tourism in KUA are the distance traveled to the tourist sites and the length of time knowing the existence of tourism. The economic value of the tourist area amounted to Rp40.058.337.838. (2) The resulting economic impact has impacted the local community but the value is still low. (3) KUA has strengths in mangrove educational tourism offerings and weaknesses of KUA is a tourist attraction that is still not developed optimally so that the recommendation of priority development strategy is the development of rides and tourist attractions.

Judul: Economic Value Estimation and Management Strategy of Mulyaharja's Organic Agro Edutourism
Abstrak: Sektor pariwisata adalah sektor yang sangat potensial untuk meningkatkan perekonomian nasional. Aktivitas ekonomi dalam wisata sangat dipengaruhi oleh preferensi konsumen dalam memilih atraksi wisata. Aktivitas wisata terutama wisata alam menghasilkan layanan jasa lingkungan yang dapat diperhitungkan sebagai nilai ekonomi. Namun, keterbatasan mekanisme pasar untuk mengukur nilai jasa wisata alam menyebabkan jasa wisata cenderung dinilai lebih rendah (undervalue). Tujuan penelitian ini adalah mengidentifikasi pola permintaan wisatawan, mengestimasi nilai ekonomi, menganalisis daya dukung kawasan dan merumuskan strategi dalam mengelola kawasan wisata. Metode yang digunakan yaitu Analisis Deskriptif, Travel Cost Method, Physical Carrying Capacity, Real Carrying Capacity dan Effective Carrying Capatiy, Analasis SWOT dan Quantitative Strategic Planning Matrix (QSPM). Hasil penelitian menunjukkan bahwa wisatawan menilai Agro Eduwisata Organik dalam kondisi baik walaupun terdapat kekurangan pada aspek penilaian kualitas air, fasilitas wisata dan aksesbilitas. Tujuan wisatawan terhadap lokasi wisata yaitu wisatawan mengunjungi untuk menikmati pemandangan/Landscape. Nilai ekonomi di kawasan yaitu sebesar Rp 256.250.000 per tahun. Secara umum daya dukung kawasan Agro Eduwisata Organik Mulyaharja mengalami over carrying capacity pada beberapa atraksi, tetapi pada atraksi lainnya masih under carrying capacity. Strategi yang menjadi prioritas utama yaitu mengevaluasi dan mengembangkan pembangunan objek wisata dengan berkerjasama dengan investor atau pemda., The tourism sector is a sector that has the potential to improve the national economy. Economic activity in tourism is strongly influenced by consumer preferences in choosing tourist attractions. Tourism activities, especially nature tourism, produce environmental services that can be calculated as economic value. However, the limitations of market mechanisms to measure the value of natural tourism services cause tourism services to tend to be undervalued (undervalue). The purpose of this study is to identify patterns of tourist demand, estimate economic value, analyze the carrying capacity of the area and formulate strategies in managing tourist areas. The methods used are Descriptive Analysis, Travel Cost Method, Physical Carrying Capacity, Real Carrying Capacity and Effective Carrying Capacity, SWOT Analysis and Quantitative Strategic Planning Matrix (QSPM). The results showed that tourists rated Organic Agro Edutourism in good condition although there were deficiencies in aspects of water quality assessment, tourist facilities and accessibility. The purpose of tourists to tourist sites is that tourists visit to enjoy the scenery/landscape. The economic value in the area is IDR 256,250,000 per year. In general, the carrying capacity of the Mulyaharja Organic Agro-Edutourism area is experiencing over carrying capacity at some attractions, but other attractions are still under carrying capacity.The strategy that becomes the main priority is evaluating and developing the development of tourist objects in collaboration with investors or local governments.

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.
