The information on land cover changes is very important in regional spatial planning. Remote sensing technology can minimize the cost and time in analyzing land cover changes. Normalized Difference Vegetation Index (NDVI) is a vegetation index that combines red and near-infrared channels so that it can provide approximate information about land cover in an area. The objective of this study is to extract land cover change information from Landsat 8 images based on NDVI values in Bangli Regency in 2015 and 2021. The classification method used to estimate the type of land cover is supervised classification. The results reveal the decrease of the land cover in the category of water body, sand, dry land/soil, rice fields, and vegetation, which are 1.62%, 14.14%, 7.93%, 8.63%, and 2.45%, respectively, while an increase in the settlement category by 30.12%. The overall accuracy of land cover classification result based on NDVI value is 86.54%.

Rainfall data is critical for planning and research in the field of hydrology. Rainfall data must be available continuously, which means it must be recorded continuously. This recording will continue since numerous projects in the field of hydrology require continuous rainfall data. Although rainfall data are collected and recorded daily, some stations frequently have insufficient rainfall records, particularly in developing countries such as Bali, Indonesia. These issues may impair the quality of rainfall data, resulting in inaccuracies in the analysis results. To address this issue, we need a reliable source of rainfall data, one of which is NASA Power, which provides rainfall data for free. NASA Power rainfall data is then compared to observed rainfall data. The comparison of the two rainfalls is measured by a statistical parameter, namely the correlation coefficient. Based on the comparison between lowland and highland areas, the average daily rainfall from NASA Power tends to be lower than the average daily rainfall from observation stations. Meanwhile, from the correlation coefficient value (r) of the comparison of rainfall observations and NASA Power, a considerably high correlation coefficient value (> 0.7) was observed. Thus, it can be suggested that the rainfall data from NASA Power for hydrology research and planning activities in Bali Island, Indonesia.

Saba Irrigation Area is located in Gerokgak and Seririt District, Buleleng regency, Bali. The assessment of the irrigation performance index is required to maintain the value of irrigation asset function and condition. Some problems occur in the irrigation area from the standard area of 1548 ha, but the productive land is around 889 ha or about 57% of the standard area. The problems were found in the irrigation canal, which hampered the performance of irrigation downstream, where water cannot flow to rice fields. The wet cross-section of the channel is covered by sediment. Even at several locations, the sediment height has the same elevation as the surrounding surface. The purpose of this study is to obtain value in the form of an assessment index on the primary and secondary irrigation systems, which will be classified into their respective components. Furthermore, rehabilitation priority is determined using the decision-making method with the Analytic Hierarchy Process (AHP) and Analytic Network Process (ANP). The assessment of irrigation performance index scored 62.94% consisting of physical infrastructure 29.28%; crop productivity 7.24%; supporting facilities 4.95%; personnel organization 10.75%; documentation 3.40%; and water user associations 7.33%. Determining the rehabilitation priority using the AHP method and ANP method showed the same results, i.e. physical infrastructure in rank 1, personnel organization in rank 2, crop productivity in rank 3, water user associations in rank 4, supporting facilities in rank 5, and documentation in rank 6. Determination of the selected rehabilitation in the physical infrastructure aspect is the sub-aspect of irrigation channels. Irrigation channels get the highest score with the worst damage conditions from all sub-aspects.

Prestressed concrete is the perfect composite consisting of high-strength concrete and strands with reinforcement with high yield strength Prestressed concrete beam is one of the concrete innovations that have been used in many constructions. The advantage of prestressed concrete particularly using the post-tensioning method, in designing and applying prestressed concrete beam for the building is that the tensioning can be carried out in stages, for all tendons in a member, or some of them Prestressed concrete beam using post-tensioning method can be an alternative to increase the span of the building when removing the existing column in the center of the building is required. In this paper, the use of prestressed concrete beam will be designed in Nyitdah Hospital-Tabanan, Bali. The prestressed beam is designed with 60/90 cm dimension and 1 tendon unit with 12 strands unit. Based on the design and result, the prestressed beam can be used as the alternative to increase spans in a building room of the Nyitdah hospital.

Review: land, cloud, and climate change (in focus: Borneo) Jason Pajimola Punay; Ratri Andinisari

Publisher : Master Program of Infrastructure and Environmental Engineering, Postgraduate Program, Warmadewa University

This article discusses the salient findings of the Intergovernmental Panel on Climate Change Special Report on Climate Change and Land (2019). Local impacts of global warming in Borneo are discussed in terms of changes in temperature and precipitation. A drier and warmer climate is expected with the continued deforestation of Borneo. Changes in land surface characteristics of Borneo also affect the properties of cloud that forms over it. Deforested areas are generally associated with diffused clouds, small cloud particles, and thin and high clouds. Low vegetative areas are associated with a low evapotranspiration rate and low amount of latent heat release, which discourages the formation of convective clouds. The weak updraft associated with a non-convective cloud cannot support the formation of large cloud droplets. Moreover, the deforestation of primary forests of Borneo and replacing them with palm trees may cause larger cloud properties’ variability over the area.

This study focuses on strengthening scheme of an existing structure with added story. The addition of a new story increases gravitational loading, which affects the seismic and wind responses of the structure and, as a consequence, the loading combination. To ensure the structure’s capacity requirement, the strengthening scheme uses CFRP (Carbon Fiber Reinforced Polymer). In order to adequately define the structure's performance, a series of structural analyses were performed. The structure's state before and after story addition, subsequently the state after CFRP strengthening, were evaluated. It is demonstrated that the additional story to the structure causes an exceedance in internal forces; however, the strengthening with CFRP is sufficient to withstand these forces, proving that the strengthening scheme is effective and beneficial.

Railway subgrade is a layer consisting of soil material which can be in the form of natural soil, repaired material, and in the form of embankment of selected soil material that meets the specifications. The subgrade that meets the requirements is soil with a minimum CBR value of 8% with a minimum thickness of 30 cm. This study aims to analyze and evaluate the CBR value of the railway subgrade. Subgrade analysis was carried out on the improvement of the railway - replacement of concrete pads and rails R.25/33/42 to R.54 concrete pads from km 39 + 100 to km 40 + 200 along 1100 m in Perbaungan North Sumatra. The structure of the soil layer that is analyzed is the structure of the subsoil in the form of subgrade. The CBR value of the subgrade in the form of soil is determined based on the results of the analysis of the DCP data. The CBR value is evaluated based on the provisions that apply to the railway subgrade. The behavior of the railway subgrade can be seen from the CBR value of the original subgrade. Based on the results of the analysis, it was found that the behavior of the railway subgrade was quite diverse and it was found that only 39% met the requirements for the rail subgrade. Handling carried out in the field to improve the behavior of the subgrade is by using a backfill system made of good material with a density and CBR value that meets the requirements for railways.

A severe flood hit South Kalimantan in 2021. The flood inundated several cities and regions, including Banjamasin City and its surrounding areas in the Martapura Basin. According to data from the National Disaster Management Agency (BNPB), over 20,000 houses were flooded, and over 100,000 people were forced to relocate. Many flood causes are being debated these days, including climate change issues which are triggered by many factors. However, the significant factor indicating its existence is the increase in temperatures. Rising temperature will result in the intensity of the extreme rainfall and the change of its pattern. Due to this background, this study aims to evaluate rainfall and temperature variability as an indicator of climate change in the study area. The Man-Kendall Test is used in this study to analyze a trend analysis and its relationship to rainfall. The results show a temperature trend of 0.2 to 0.3 degrees Celsius over the last two decades. It indicates that climate change has occurred on a local scale. Further, the trend of rainfall and temperature have increased in all selected locations. The annual rainfall over the last 20 years has also increased by roughly 25 mm per annum.
