Judul: Economic Analysis and Development Strategy of Randusanga Indah Beach Tourism Brebes, Central Java
Abstrak: Pantai Randusanga Indah merupakan salah satu destinasi wisata di Kabupaten Brebes yang dapat dengan mudah diakses dan menarik perhatian banyak pengunjung. Pengunjung Pantai Randusanga Indah mengalami penurunan dari tahun 2019 hingga 2022. Penurunan ini disebabkan oleh minimnya promosi, rusaknya jalan menuju pantai, masalah sampah, dan kurangnya atraksi yang ditawarkan. Tujuan penelitian ini adalah 1) mengidentifikasi persepsi wisatawan, 2) mengestimasi nilai ekonomi wisata, 3) mengestimasi manfaat ekonomi wisata, dan 4) menganalisis strategi pengembangan wisata. Metode yang digunakan dalam penelitian ini adalah skala likert, travel cost method, analisis kontribusi penerimaan, dan PROMETHEE. Hasil penelitian menunjukkan bahwa persepsi wisatawan memiliki skor rata-rata 2,31, yang menunjukkan penilaian yang kurang baik terutama pada aksesibilitas. Nilai ekonomi objek wisata ini sebesar Rp 124.381.551 per tahun. Manfaat ekonomi pariwisata bagi masyarakat dengan persentase penerimaan total tenaga kerja rata-rata 75 persen dan persentase penerimaan total pelaku usaha rata-rata 73 persen. Salah satu strategi pengembangan yang dapat diprioritaskan adalah kebijakan promosi melalui media sosial dengan skor 0,551., Randusanga Indah beach is one of the tourist destinations in Brebes that can be easily accessed and attracts the attention of many visitors. The number of visitors to Pantai Randusanga Indah has experienced a decline from 2019 to 2022. This decrease is caused by promotion efforts, attributed to the damaged road leading to the beach, waste management issues, and a lack of offered attractions. The objectives of this research are to identify tourists’ perceptions, to estimate the economic value, to estimate benefits of tourism, and to analyze tourism development strategies. The methods used in this study include likert scale, travel cost method, income contribution analysis, and PROMETHEE analysis. The research findings indicate that tourists’ perceptions have an average score of 2,31, indicating relatively poor ratings, especially accessibility. The economic value of this tourist destination is estimated to be IDR 124.381.551 per year, with tourism providing economic benefits to the local community. an Average total labor income contribution of 75 percent and an average total business income contribution of 73 percent. One of the prioritized development strategies is implementing a promotion policy through social media, with a score of 0,551.

Judul: Membran Komposit Kitosan-Zeolit untuk Aplikasi Direct Methanol Fuel Cell
Abstrak: Direct methanol fuel cell (DMFC) is a fuel cell that utilize methanol as the fuel source. The electrolyte membrane used in the DMFC system in this research was chitosan-zeolite composite membrane. The composite membrane was synthesized with chitosan-zeolite composition variation of 1:1, 1:2, 1:3, and 2:1. The membranes were analyzed by Fourier transform infrared spectrophotometer (FTIR) and scanning electron microscope, and for the specific gravity. Membrane performances were tested with methanol uptake, methanol permeability, conductivity, and potential difference in the DMFC system. The FTIR spectrum showed no formation of new functional groups inducating that the composite membrane was a result of physical mixing. Morphological analysis showed that the membrane was nonporous. Chitosan-zeolite 1:3 composite membrane had the highest specific gravity and methanol uptake, 1.4226 g/mL and 41.44%, respectively. The highest proton conductivity was showed by the 1:2 chitosanzeolite composite membrane, namely 7.2946× 10-7 S/cm. Based on this research results, chitosan-zeolite composite membrane can be applied in DMFC system.
