Judul: Mitigation Strategy of Risk of Covid-19 Spread on Marine Toursim in Pahawang Island
Abstrak: Pulau Pahawang merupakan salah satu wisata bahari yang terkena dampak pandemi Covid-19. Sejak adanya pandemi Covid-19, terjadi penurunan dratis pada jumlah wisatawan yang mengunjungi Pulau Pahawang. Oleh karena itu, pada wisata bahari Pulau Pahawang diperlukan: (1) analisis persepsi masyarakat pelaku wisata terhadap risiko penyebaran Covid-19 (2) analisis nilai prioritas risiko penyebaran Covid-19 (3) analisis strategi mitigasi risiko yang tepat untuk mengatasi risiko penyebaran Covid-19. Jenis penelitian ini menggunakan data primer dengan penelitian kuantatif. Penelitian menggunakan analisis mitigasi risiko dengan metode Failure Mode and Effect Analysis (FMEA) dan metode Analytichal Hierarchy Process (AHP). Hasil penelitian menunjukkan bahwa persepsi masyarakat pelaku wisata terhadap risiko penyebaran Covid-19 termasuk dalam kategori sedang. Hasil analisis nilai risiko menunjukkan bahwa pantai memiliki risk priority number tertinggi dengan nilai 630. Strategi mitigasi yang tepat untuk dilakukan adalah mengizinkan seluruh wisatawan berwisata di Pulau Pahawang dengan membatasi pembukaan wahana yang berisiko rendah.

Judul: Analisis Dampak Ekonomi dan Strategi Pengelolaan Wisata yang Adaptif Pasca Covid-19 di Pulau Pahawang Lampung
Abstrak: Covid-19 memberikan dampak buruk bagi pariwisata di Indonesia. Tekanan pada industri pariwisata sangat terlihat dengan penurunan yang besar pada jumlah wisatawan. Akibat adanya kebijakan pembatasan menyebabkan kunjungan wisata mengalami penurunan. Kawasan wisata Pulau Pahawang merupakan wisata unggulan di Lampung dan lokasi wisata ini menjadi lokasi sumber mata pencaharian masyarakat sekitar, namun dengan adanya Covid-19 memberikan dampak buruk bagi kegiatan wisata. Berdasarkan hal tersebut penelitian ini bertujuan untuk (1) menganalisis dampak ekonomi yang timbul sebelum dan saat pandemi Covid-19 di Kawasan Wisata Pulau Pahawang; (2) mengestimasi daya dukung kawasan wisata Pulau Pahawang sebelum dan saat pandemi, (3) menganalisis strategi adaptif pengelolaan kawasan wisata Pulau Pahawang akibat pandemi. Metode analisis yang digunakan pada penelitian ini adalah multiplier effect, daya dukung fisik, dan Analitycal Hierarchy Process (AHP). Hasil penelitian menunjukkan bahwa hadirnya pandemi Covid-19 menyebabkan nilai Keynesian Income Multiplier mengalami penurunan dan nilainya kurang dari satu sehingga memberikan dampak yang rendah. Sementara itu Ratio Income Multiplier tipe I dan II mengalami kenaikan dan memilki nilai lebih dari satu sehingga berdampak baik bagi masyarakat. Daya dukung kawasan wisata Pulau Pahawang berada pada under carrying capacity, dimana sebelum Covid-19 sebesar 10.436 orang/hari dan saat Covid-19 sebesar 7.693 orang/hari. Alternatif strategi pengelolaan yang akan dilakukan adalah pengelolaan potensi SDA dan SDM., Covid-19 has had a negative impact on tourism in Indonesia. The pressure on the tourism industry is very visible from the large decline in the number of tourists. Tourist visits have decreased as a result of the restriction policy. The Pahawang Island tourist area is a leading tourist area in Lampung and this tourist location is a source of livelihood for the local community, but the presence of Covid-19 has had a negative impact on tourism activities. This study aims to (1) analyze the economic impact that arose before and during the Covid-19 pandemic in the Pahawang Island Tourism Area; (2) estimating the carrying capacity of the Pahawang Island tourism area before and during the pandemic; and (3) analyzing post-pandemic adaptive strategies for managing the Pahawang Island Tourism Area. The analytical methods used in this study are the multiplier effect, carrying capacity analysis, and the Analytical Hierarchy Process (AHP). The results showed that the presence of the Covid-19 pandemic caused the Keynesian Income Multiplier value to decrease, but the Type I and II Income Multiplier Ratios each increased so that it had a good impact on society. The carrying capacity of the Pahawang Island tourist area is at under carrying capacity, with 10.436 people/day before Covid-19 and 7.693 people/day during Covid-19. An alternative management strategy that can be carried out is management of potential natural recources and human recources.

Judul: Biological Characteristics of Jatropha curcas Trimonoecious
Abstrak: Physic nut (Jatropha curcas L.) is an original plant from tropical America belonging to the family of Euphorbiaceae and an annual plant of monoecious. Commonly J.curcas have male and female flowers on the same plant. There are currently some J. curcas which have hermaphrodite flowers from monoecious plants, but very rarely. J. curcas with hermaphrodite flowers are classified as andromonoecious type (having hermaphrodite and male in the same plant) and trimonoecious type (having male, female, and hermaphrodite flowers in the plant). Trimonoecious plants with hermaphrodite flowers were tend to perform self-pollination (geitonogamy) and produce a homogenous and high-productivity in next generation. J. curcas plants is difficult in differentiating between monoecious and trimonoecious plants when it seedling, and this is a limiting factor to know development of trimonoecious J. curcas. Trimonoecious J.curcas can be identified after six months of planting, and when it have started flowering. Therefore, the trimonoecious J. curcas biological characteristics needs to be an observation. The trimonoecious trait in J. curcas plants can be identified through several analyses, i.e. the analysis of agronomical characteristics, the chromosomes analysis, the isozyme analysis, and the analysis of pollen viability. The study was conducted in December 2011 - February 2013. The experiments were conducted using the Randomized Complete Block Design for one factor, the J. curcas genotype with 5 replicates. Each unit of the experiment consisted of 5 plants. Aagronomics characteristic analyses were conducted using analysis of variance (ANOVA) followed by the Duncan Multiple Range Test (DMRT) at 5% level. The classification of heritability and Genetic Variation Coefficient (GVC) criteria and relative Phenotypic Variation Coefficient (PVC). The analysis of genetic distance clustering was done using the Minitab 1.5 program clustering method. J. curcas stem trimonoecious characters is the primary branches angle, stem diameter, number of primary and secondary branches have a higher size than monoecious plants. Diameter and thickness fruit flesh origins from monoecious plants larger than fruit from plants trimonoecious. Characteristics of the trimonoecious plants in this study were almost the same with their mother plant. Number chromosomes number of J. curcas plant genotypes have 2n = 22 chromosomes The average length of the trimonoecious plant’s chromosome was longer than the average for monoecious plants. The length of chromosomes can differ among one family, even though the numbers of the chromosomes are similar. Isozymes peroxidase (Rf 0.83) and esterase (Rf 0.20) could be used as markers to differentiate between trimonoecious and monoecious plants. Male flower pollen viability of plant origin trimonoecious have a slower rate of decrease than male flowers monoecious plants. The dendrogram from the cluster analysis results could differentiate between trimonoecious and monoecious plants with a variation coefficient of 27.25.
