Abstract

Badung Regency is a very famous tourist destination to foreign countries. However,most of these tourist destination areas are located in disaster-prone areas. This studyaims to determine the role of disaster-resilient villages in providing security and comfortto tourists visiting tourist objects. This study used a descriptive-analytic method with adesk study design. Disaster Resilient Villages / Kelurahan are villages that have theindependent ability to adapt and face potential disaster threats. Currently, there are 31disaster-resilient villages in Badung Regency, most of which are tourist destinationareas. In disaster-resilient coastal areas, the potential for tsunami disasters, highlandareas are potentially affected by landslides. The prevention and mitigation efforts thathave been carried out by the Badung Regency Government include; build an earlywarning system, install warning signs, carry out disaster simulations and disseminateinformation to the public.

Abstract

Salah satu Provinsi di pulau sumatera yang paling rentan terhadap bencana gempa bumi ialah Provinsi Bengkulu, yang wilayahnya terletak pada zona pertemuan lempeng tektonik Indo- Australia dan Eurasia yang merupakan pemicu utama tingginya aktivitas gempa bumi di wilayah Provinsi Bengkulu. Penelitian ini dilakukan untuk mengidentifikasi distribusi kegempaan, b-value, a-value, periode ulang gempa bumi dan kemungkinan gempa di wilayah Provinsi Bengkulu dengan menggunakan metode Maximum Likelihood. Data gempabumi yang digunakan dalam penelitian ini adalah data gempabumi dari katalog USGS tahun 1914-2020 kurun waktu 106 tahun dengan magnitudo completness 5.3 dan kedalaman (h) ? 8.9 km yang berlokasi di 5o 40’– 2o 0’ LS dan 40’ – 104o 0’ BT. Data latitude dan longitude di bagi menjadi 2 bagian berdasarkan sebaran episenter gempa. Hasil penelitian menunjukkan bahwa distribusi kegempaan di Provinsi Bengkulu sebanyak 1442 kejadian gempa selama 106 tahun terakhir. Distribusi kegempaan di Provinsi Bengkulu cukup tinggi. Dari analisis menggunakan software ZMAP diperoleh dari hasil distribusi b-value wilayah Provinsi Bengkulu terlihat wilayah laut memiliki b-value yang cenderung lebih rendah dengan variasi 1.5–1.9, dengan wilayah perairan laut Bengkulu timur hingga tenggara merupakan wilayah dengan variasi b-value tertinggi. Sedangkan untuk b-value wilayah darat dengan variasi yang lebih tinggi yaitu antara 2.8–3.2, yang merupakan Wilayah yang dekat dengan pinggir pantai dengan periode ulang gempa dengan magnitudo 6-7 berkisar antara 4 – 7000 tahun.

Abstract

Plant roots and litter produced by tree that grow have an important role in the entry of rainwater into the soil (infiltration) as water storage in the future. The effects of plant roots and litter on increasing infiltration rate is due to increased soil macroporosity. The presence of roots that spread in various layers in the soil profile will further increase the organic matter content of the soil and loosen the soil thereby increasing soil macroporosity. In addition, dead roots will form empty spaces that can be filled by infiltration water, as well as active roots that have gaps between roots and soil that can be filled infiltration water. The high infiltration rate will reduce the amount of excessive runoff water so as to reduce the occurrence of erosion.

Abstract

Changes in human activities from time to time increase rapidly. This activity requires the support of a reliable transportation network. Railroad land transportation is the main choice to overcome the impasse of human mobility and distribution of goods. It is known that this type of transportation does not intersect with other means of transportation so that it is free from congestion. For the sake of smoothness and safety in the use of trains, proper maintenance of the rail network is needed. Land subsidence supporting the railroad tracks is a common event that disrupts the functioning of the railroad and is part of maintenance. One of the subsidence that often occurs on the railroad tracks is a subsidence on the railroad tracks around Ujungnegoro Station. To find out the cause, an analysis of geoelectric data, groundwater basin conditions and local topography has been carried out on it. The results of the analysis that have been carried out conclude that the clay content factor and the concentration of water flow are the main factors causing subsidence.

Abstract

Mangrove ecosystem has high productivity both ecologically and economically. Mangroveecosystems have the ability to store high carbon which is useful in supporting the reduction ofgreenhouse gas emissions. The results of previous studies have shown that mangroveecosystems are able to store carbon three to four times greater than terestrial forests. Most ofthe carbon are stored in the soil. Therefore, ecosystem mangroves have an important role tomitigate climate change. However, mangroves can be effective in supporting the mitigation ofcarbon dioxide emissions if mangrove deforestation rates are low. However, mangroves canstill contribute with great potential when conservation are maintained to increase future carbonstocks through restoration and prevent further emissions from deforestation. Existing data andprior research indicate that mangrove forests are threatened due to mangrove coveragereduction. This is caused by changes in land use. There are many conversions of mangrovesinto cultivation ponds, as well as conversions into agricultural land such as paddy fields andpastures, accompanied by an increase in demand for oil palm which causes land clearing. Inaddition, the population around the coastal area is increasing, resulting in the clearing ofmangrove land for infrastructure development such as road and port construction. In order toreduce the rate of mangrove deforestation, it is necessary to conserve and restore mangroves.By preserving mangrove forests, not only maintain carbon stocks for climate change mitigationbut also facilitate adaptation to climate change such as sea level rise.
