Purbalingga is regency with a potential moderately high seismicity requiring compliance of planning and implementation rules of the earthquake-resistant structural system. The purpose of this research is to evaluate the performance of a ten-story irregular apartment building model in Purbalingga due to the seismic load. The study is necessarily conducted to provide information on impacts and mitigation strategies that should be implemented. This research was conducted based on the seismic capacity of 2002 and 2012 Indonesian National Standard (SNI) including linear static analysis, dynamic response analysis, and pushover analysis. Based on the direct static review, it shows that the base shear is reduced and the drift ratio level decreases respectively for X and Y direction.Meanwhile, based on the dynamic response analysis, the drift ratio level also decreases respectively for X and Y direction. Also, the pushover analysis indicates that the performance of this apartment building model is still at Immediate Occupancy (IO) level as the post-earthquake damage state that remains safe to occupy, essentially retains the pre-earthquake design strength and stiffness of the structure. The risk of life-threatening injury as a result of structural damage is very low, and although some minor structural repairs may be appropriate, these would generally not be required before occupancy

This article described the spatial and temporal of land surface temperature (LST) patterns in Banda Aceh City, Indonesia, in the context of urban heat island (UHI) phenomenon. Landsat imaginary in 1998 and 2018 was used in this study, which represents the conditions before and after the tsunami. Geographic Information System (GIS) and Remote Sensing (RS) technique were used for data analysis. The 1998 and 2018 LUC maps were derived from remote sensing satellite images using a supervised classification method (maximum likelihood). Both LUC maps contained five categories, namely built-up area, vegetation, water body, vacant land, and wet land. The 1998 LUC map had a kappa coefficient 0.91, while the 2018 LUC map had 0.84. It was found that the built-up area increased by 100%, while the vegetation category fell 50%. The overall mean LST in the study area increased 5.90C between 1998 and 2018, with the highest mean increase in the built-up area category. The study recommends that LST should be taken into consideration in urban planning process to realize sustainable urban development. It also emphasizes the importance of optimizing the availability of green open space to reduce UHI effects and helps in improving the quality of the urban environment.

Bobanehena village is geographically located in the coastal area of subduction route, causing the village to be vulnerable to frequent earthquakes. The 5 SR earthquake struck the village in 2015 caused heavy damages to people's houses. The houses that are susceptible to damage by earthquakes, resulting in many casualties. This research aim is to identify the types of house in Bobanehena village, West Halmahera Regency. Typological data of houses can be used as database for vulnerability assessment in Bobanehena village. The method used was field study, structured interviews, and documentation using field observation to determine the physical condition of houses which are responsive to earthquakes. The results of the research indicate that the residence in Bobanehena village, West Halmahera Regency is in the form of the spatial distribution of earthquakes-prone housing, which forms a longitudinal pattern and expanded to the coastal area. The characteristic of settlement distribution is unorganized and clustered, so it appears to be in a random pattern. The typology of earthquake-prone residences in Bobanehena village can be classified into three types, namely Stengah Leger house, Fala Kanci traditional house, and modern house. In addition, from those three types, Stengah Leger and Fala Kanci are responsive to the earthquake load, for it uses wooden frame construction.

a slum will cause many problems for many cities. The urbanization factor is one of the causes of slums due to the limited urban housing area. In general, there are seven slum indicators that can determine the quality of residential areas, one of which is physical infrastructure. Infrastructure conditions are interrelated with residential development. This study analyzes seven indicators of slums in Jawa Lama Village, Lhokseumawe, Aceh-Indonesia. In this study, the research team used data surveys with field tracking and field documentation from city roads. Documented data includes field photos and regional mapping that shows the location of the study. Data that has been collected can be used to determine urban facilities and infrastructure that are very influential for slums in the study area.

Groundwater availability is the main concern in a developing region such as Weh Island, Aceh. To locate groundwater resources, vertical electrical sounding (VES) was used to identify subsurface profiles. The study area is located on a volcanic island. The lithology consists of volcanic rocks as andesite lava and pyroclastic rocks as lapily-tuff until breccia. VES method was carried out in 4 measurement points using the Schlumberger array. The resistivity value used to identify subsurface lithology. The top layer of alluvium and weathered lava have resistivity ranges from 14.3 Ωm to 17.7 Ωm with thickness varies from 0 m – 17.4 m. It is followed by andesite resistivity ranges from 17.3 Ωm to 18.2 Ωm with averages thickness is 17.4 m – 35.2 m. Finally, the bottom layer is filled by breccia-tuff with resistivity value from 5.5 Ωm to 7.3 Ωm. The physical properties of some related rocks allow water accumulation to their bodies. The current polarization indicates water content in the pore space of breecia at the study area which polarization point is identified as the water table.

This study aims to analyze the effect of the working environment and motivation towards the performance of labors at the packaging department of urea fertilizer in PT. Pupuk Iskandar Muda, Lhokseumawe, Aceh, Indonesia. This study employs the census sample selection method and involves 35 labors at the packaging department in the company. The research variables consist of independent variables (i.e. physical and psychosocial working environment, work motivation, and supporting working tools) and dependent variables (i.e. labors’ performance). Based on data analysis that uses double regression (linear), it shows that the relationship between the independent variables towards the dependent variable is with R square value 46.8%. This circumstance proves that proper physical working environment that provides comfortable and safety procedures to the labors increases their performance. Moreover, the results from the regression coefficient also show a significant effect of the physical working environment, psychosocial working environment, work motivation, and supporting working tools towards the labors’ performance.
