Abstract

Indonesia memiliki banyak daerah rawan bencana. Faktor yang dapat menyebabkan terjadinya tsunami salah satunya gempa bumi yang tidak dapat dihindari mengingat posisi tata letak geografis Indonesia yang berada di Zona megathrust. Sebagian besar gempa bumi ini berpusat di dasar Samudera Hindia dan beberapa di antaranya menimbulkan gelombang laut besar (tsunami) di Pulau Jawa. Penelitian dilakukan di salah satu kabupaten yang berada di selatan Pulau Jawa yaitu Kabupaten Cilacap yang merupakan kabupaten terluas di provinsi Jawa Tengah dengan luas wilayahnya sekitar 6,2% dari total wilayah Jawa Tengah. Pemodelan tsunami dilakukan menggunakan Model Crunch untuk memprediksi tingkat risiko bencana tsunami. Metode ini merupakan hasil perkalian antara bahaya (hazard) dengan kerentanan (vulnerability). Bahaya tsunami dalam Model Crunch tersebut berupa tinggi gelombang tsunami dan luas genangan, sedangkan kerentanan berupa kepadatan penduduk, elevasi, infrastruktur, dan jarak permukiman dari pantai. Berdasarkan hasil Weighted Overlay Analysist yang dilakukan pada setiap parameter yang telah diklasifikasikan kelas kerentanannya, kerentanan wilayah pesisir Kabupaten Cilacap terhadap bencana tsunami yaitu berada pada kategori cukup rentan hingga rentan. Wilayah pesisir Kabupaten Cilacap berada pada kategori cukup rentan hingga rentan terhadap bencana tsunami, oleh karena itu perlu dilakukan penelitian lanjutan seperti alur evakuasi untuk membuat jalur evakuasi jika terjadi bencana tsunami, studi ketahanan masyarakat pesisir dalam menghadapi bencana tsunami dan upaya teknis yang dapat dilakukan melalui kegiatan relokasi, adaptasi, dan proteksi.

Abstract

Posisi geografi Indonesia berada di atas tiga lempeng aktif, yaitu lempeng Pasifik, Indo-Australia, dan Eurasia yang bergerak konstan sehingga mengakibatkan sesar. Sesar tersebar di berbagai wilayah di Indonesia, salah satunya berada di Pulau Jawa yaitu Sesar Cimandiri yang terhampar dari barat ke timur melalui Pelabuhanratu hingga Gunung Tangkubanprahu. Lokasi Sesar yang membentang di wilayah Sukabumi menyebabkan berbagai bencana, seperti gempa bumi. Sukabumi dengan garis pantai sepanjang 177 km serta potensi pergeseran sesar di wilayah pantai berpotensi menyebabkan bencana tsunami hingga ketinggian 20 m, sehingga diperlukan analisis wilayah terdampak serta jumlah penduduk terdampak. Analisis dilakukan dengan bantuan software ArcGIS dan QGIS melalui beberapa pengerjaan, seperti permodelan inundasi, permodelan kerentanan wilayah, dan analisis penduduk terdampak. Permodelan inundasi dilakukan dengan memperkirakaan ketinggian gelombang di pinggir pantai sebesar 10, 15, dan 20 meter dan kemudian dilakukan clip dengan tutupan lahan Sukabumi. Jumlah penduduk terdampak dihitung dengan data kepadatan penduduk setiap kecamatan terdampak dan dikalikan dengan luas wilayah terdampak di setiap kecamatan. Luas wilayah terdampak dengan ketinggian run-up 10 meter sebesar 6781,08 ha, pada run-up 15 meter sebesar 9703,75 ha, dan pada run-up 20 meter sebesar 12609,24 ha. Kategori tutupan yang terdampak berupa badan air, empang/tambak, hutan, lahan pertanian, lahan terbangun, lahan terbuka, perkebunan, dan semak belukar. Jumlah penduduk terdampak dengan skenario 10m, 15m, dan 20m sebanyak 74.000 hingga 135.000 jiwa. Permodelan dan analisis tersebut diharapkan memberikan informasi mengenai luasan wilayah terdampak, jenis tutupan lahan terdampak, serta jumlah penduduk terdampak sehingga penelitian dapat dikembangkan. Penelitian mengenai dampak bencana tsunami diharapkan berkembang dengan adanya perencanaan konstruksi bangunan shelter yang memenuhi standar mitigasi.

Abstract

This study aims to analyze the influence of product quality and service quality on consumer purchasing decisions at Investor Jeunieb Clothing Store in Bireuen. The research was conducted at Investor Jeunieb Clothing Store in Bireuen. The object of the research is consumers who visit Investor Jeunieb Clothing Store. The population in this study includes all consumers of Investor Jeunieb Clothing Store, the exact number of which is unknown. The sample was taken using the Hair formula, with a total sample size of 98 respondents. This study uses a multiple linear regression analysis model to determine the effect of product quality and service quality on purchasing decisions. The data was analyzed using SPSS software version 25.0. The analysis tools used include validity tests, reliability tests, classical assumption tests, multiple linear regression analysis, t-tests, F-tests, R-tests, and R-Square tests. The t-test results show that product quality with a t-value greater than the critical t-value at the 5% level (6.514 > 1.985) and a significance value of 0.000 < 0.05 and service quality with a t-value greater than the critical t-value at the 5% level (6.890 > 1.985) and a significance value of 0.001 < 0.05 have a significant effect on purchasing decisions. The F-test results indicate that the regression model used is significant with an F-value greater than the critical F-value (200.848 > 2.70) and a significance value (sig) of 0.000 < 0.05, which means that product quality and service quality together have a significant influence on purchasing decisions. The R-test results show a strong correlation between the independent variables and the dependent variable (R = 0.899). The R-Square test results indicate that 0.809 or 80.9% of the variation in customer loyalty can be explained by service quality and customer value, while the remaining 19.1% is influenced by other variables not examined in this study.

Abstract

This article outlines the development of a Fiber Bragg Grating (FBG) intended for use as a sensor for CH4 and CO2 gases. Following fabrication, the FBG was effectively treated with a layer of Graphene Material through a modified RF Sputtering process. This coating procedure involved introducing argon gas into the chamber and subjecting the FBG, securely held by two vacuum stages, to a temperature range of 27°C to 600°C by adjusting the power supplied to the cathode and anode, ranging from 0 to 125 Watts. Subsequently, the FBG was employed as a key sensing element within an experimental setup aimed at measuring gas concentrations within a confined space. The assessment involved analyzing the reflected signal of the FBG using an Optical Interrogator System, which demonstrated a shift in the Bragg wavelength of the reflected signal corresponding to varying gas concentrations. This study indicates promising outcomes for the Graphene-coated FBG as a gas sensor. The sensor’s sensitivity was evaluated based on the Bragg wavelength shift resulting from gas presence within the chamber. The Graphene-coated FBG exhibited sensitivities of 3.3 ppm for CH4 and 3.7 ppm for CO2, surpassing those reported in prior research efforts.
