Abstract

Matahari adalah sumber energi terbesar dan utama bagi kehidupan, kita dapat memanfaatkan energi matahari secara cuma-cuma dengan teknologi secara sederhana, oleh karena itu penggunaan energi matahari dapat di jadikan sebagai salah satu alternative. Hingga kini permasalahan mengenai sumber energi masih terus berlangsung, namun persediaan energi yang ada semakin berkurang. Untuk itu inovasi tentang energi alternatif, terutama dari sumber daya dari non fosil sangat diperlukan seiring perkembangan ilmu pengetahuan dan teknologi saat ini. Salah satu alternatif yang dapat kita lakukan adalah dengan menggunakan energi baru terbaharukan, yaitu energi matahari yang dirubah menjadi energi listrik. Driver motor ini yang nanti nya menggerakan panel surya untuk mencari arah datang nya sinar matahari. Driver motor akan berhenti ketika dari salah satu LDR atau kedua nya mendapat cahaya maksimal. Berdasarkan hasil pengujian didapatkan bahwa berdasarkan tabel keseluruhan, komponen telah bekerja dengan baik dan sesuai dengan rancangan. Kelebihan dari alat ini adalah dapat bekerja pada alat elektronik yang mempunyai sumber DC dan alat ini mempunyai dua sumbu putar. Pada pengujian sistem panel surya menunjukkan tegangan terukur nya mempunyai selisih yang tidak jauh dengan tegangan keluaran nya, yaitu antara 0.1 Volt sampai 0.3 Volt. Pada pengujian sensor LDR menunjukkan perbedaan V resistansi nya antara LDR 1 dan LDR 2 berbeda.

Abstract

Tujuan dari penelitian ini adalah menghitung kerugian ekonomi rusaknya terumbu karang akibat tabrakan kapal Caledonian Sky di Raja Ampat dan merumuskan kebijakan terkait penanggulangan kerugian ekonomi rusaknya terumbu karang akibat tabrakan. Metode yang digunakan dalam penelitian ini adalah studi literatur dengan mengkaji berbagai literatur, data pendukung serta hasil studi yang telah dilakukan oleh berbagai pihak terutama yang berhubungan dengan penelitian. Analisis data yang digunakan mengacu pada PERMEN Lingkungan Hidup No 7 Tahun 2014 tentang Kerugian Lingkungan Hidup Akibat Pencemaran dan/atau Kerusakan Lingkungan Hidup.  Data yang diperoleh dari hasil penelusuran literatur selanjutnya dianalisis menggunakan metode benefit  transfer. Analisis lainnya adalah analisis habitat equivalent analysis yang menghitung ukuran atau skala perproyek restorasi yang dibutuhkan untuk mengembalikan layanan sumberdaya ke kondisi awal dan analisis deskritif yang dilakukan terhadap angka yang didapat dari hasil analisis dan sebagai dasar estimasi besaran kerugian yang diklaim oleh pemerintah Indonesia terhadap pihak Kapal Caledonian Sky. Berdasarkan hasil analisis estimasi jumlah kerugian ekonomi rusaknya terumbu karang akibat tabrakan Kapal Pesiar Caledonian Sky di Raja Ampat sebesar 23 juta US Dolar dengan luasan terdampak 18.882 m2 dan rekomendasi kebijakan yang dapat diambil sebagai opsi pemerintah untuk menghadapi kerusakan terumbu karang akibat tabrakan Kapal Pesiar Caledonia Sky adalah mempertimbangkan untuk mengadakan negosiasi penyelesaian sengketa tentang tuntutan kerugian  kepada perusahaan kapal pesiar Inggris Caledonian Sky atas rusaknya terumbu karang diluar pengadilan dan mempertimbangkan langkah hukum untuk menuntut ganti rugi kepada perusahaan kapal pesiar Inggris Caledonian Sky sesuai dengan hukum yang berlaku di Indonesia. Title: Estimated Economic Loss Of Coral Reefs Due To Ship Caledonian Sky Shipping In King AmpatThis study aims to calculate the economic loss of coral damage due to collision of Caledonian Sky cruise vessels in Raja Ampat and formulate policies related to the economic loss mitigation of coral damage due to collision. The method that used in this study is study of literature by reviewing various literature, supporting data and study results that have been done by various parties and related to this study. The data analysis that is used refers to Regulation Minister of Environment No. 7 of 2014 on Environmental Losses Due to Pollution and / or Environmental Degradation. Data that are obtained from literature searching results then analyzed by using benefit transfer method. Another analysis is the habitat equivalent analysis that calculate the size or scale of the restoration project that needed to return resource services to initial conditions and descriptive analysis of the figures that obtained from the analysis and as a basis for estimating the amount of losses that claimed by the Indonesian government against the Caledonian Skycruise vessel. Based on the results of the estimation analysis, the amount of economic loss from coral damage due to the collision of Caledonian Sky Cruise vessel in Raja Ampat is 23 million US Dollars with an affected area of 18,882 m2. The policy recommendations that can be taken as the government option to deal with coral reef damage due to collision of Caledonia Sky Cruise is considering negotiation on the settlement of disputes concerning the claims of losses to British cruise vessel Caledonian Sky on the destruction of coral reefs outside the court and considering legal action to indemnify the British cruise vessel corporation Caledonian Sky in accordance with Indonesian law.

Abstract

The current trend in nature tourism has led to increased tourist visits to coastal areas, including destinations prone to disasters and previously exposed to tsunamis. This research, which aims to analyze the variables influencing tourists' desire to revisit disaster-prone areas, addresses a crucial and timely topic in tourism and disaster management. The research utilized a quantitative approach through a questionnaire-based survey of domestic tourists visiting the Pangandaran Beach Area in West Java, known for its susceptibility to tsunami disasters. The study involved 307 respondents who completed questionnaires between June and July 2023. Data analysis employed Partial Least Square – Structural Equation Model (PLS-SEM) analysis. The findings indicate a moderate level of association among the variables studied, with an R2 coefficient of 0.521. This suggests that destination image, risk perception, regional attractiveness, and knowledge of disaster risks collectively influence tourists' intentions to revisit. Notably, the variable "knowledge" did not significantly impact destination image and revisit intention but did influence risk perception. Additionally, risk perception was identified as a determinant influencing tourists' decisions to revisit Pangandaran. The research underscores the critical role of risk perception in influencing tourists' behavior in disaster-prone areas. This research highlights educating tourists about disaster risks and integrating individual factors in planning, as both influence revisits to disaster-prone destinations.

Abstract

This study explores how destination attributes, such as accessibility, natural attractions, facilities, and disaster knowledge, influence tourists' risk perceptions, ultimately shaping their travel preparedness. Data were collected through questionnaires distributed to 806 tourists visiting a tsunami-prone beach destination in Indonesia. Partial Least Squares Structural Equation Modeling (PLS-SEM) was implemented in the analysis. The findings indicate that accessibility and well-developed tourist facilities tend to lower tourists’ perceived risk, while disaster knowledge heightens it, leading to improved preparedness. Tourists generally feel safer when destinations offer accessible amenities and infrastructure, yet this sense of security may inadvertently decrease their readiness for disasters. This situation creates a paradox: While enhanced accessibility and high-quality amenities contribute to visitor satisfaction, they can unintentionally lower risk perception and preparedness levels. The study challenges the conventional view that accessibility and amenities are inherently beneficial, highlighting the importance of balancing these attributes with proactive risk management strategies. Destination providers, destination management organizations (DMOs), and governments should enhance tourists’ disaster awareness through well-crafted guidelines, educational campaigns, and community engagement programs; these efforts help equip tourists with the necessary knowledge to respond effectively in emergency situations. At the same time, they contribute to the development of safer and more enjoyable tourist destinations.
