Abstract

The peat fire events in Indonesia, particularly the South Sumatra area, changed the appearance of surface vegetation. The fires usually occur during the dry season from July to October. This study aims to evaluate land cover changes due to 2015’s peat fire in the South Sumatra peatlands. Remote sensing techniques using a Normalized Difference Vegetation Index (NDVI) method were used to identify the change of vegetation density in the study area. The results showed that 69% of the total South Sumatra peatland was burned due to the 2015 peat fire event. The level of vegetation density was considerably decreased by fire events. The degradation in the burned area was dominated by land cover class of ferns/shrub. The Peat fires during the observation period have a negative impact on the peat ecosystem, so improvements are needed in peatland management practices. Improvements need to be made in fire prevention and management practices, as well as restoration of burnt land.

Abstract

ABSTRAKGedung asrama Institut Teknologi Sumatera (ITERA) memanfaatkan air tanah dalam memenuhi kebutuhan air bersih penghuninya, namun kuantitas air tanah pada asrama TB 4 ini tidak cukup untuk memenuhi kebutuhan air bersih, sehingga dibutuhkan transfer air dari asrama lain. Untuk itu diterapkan Pemanenan Air Hujan (PAH) sebagai alternatif penyediaan air bersih dan sebagai upaya dalam memanfaatkan air hujan. Air hujan yang dapat ditampung dipengaruhi oleh curah hujan harian maksimum menggunakan analisis hidrologi. Metode analisis hidrologi ini bertujuan untuk menganalisis kuantitas air hujan yang dapat tertampung melalui atap Asrama TB 4 ITERA. Data curah hujan yang dipakai pada perencanaan ini yaitu data dari BMKG Radin Inten Lampung Selatan. Untuk mendapatkan curah hujan dihitung menggunakan distribusi terpilih yaitu log pearson tipe III dan intensitas hujan menggunakan metode mononobe dengan PUH 5 tahun selama 2 jam sebesar 24.78 mm.hari-1. Dari curah hujan tersebut didapatkan dimensi talang, pipa tegak, pipa datar, dan pipa pencucian atap berukuran 5 inci. Sedangkan volume air hujan yang dapat tertampung sebanyak 10.100 liter per harinya. Perencanaan pemanenan air hujan di asrama TB 4 ITERA ini memerlukan biaya sebesar Rp. 65,532,800.00.Kata kunci: air hujan, asrama, curah hujan, hidrologiABSTRACTThe dormitory building of the Sumatra Institute of Technology (ITERA) utilizes ground water to meet the clean water needs of its residents, but the quantity of ground water in the TB 4 hostel is not sufficient to meet clean water needs, so water transfers from other dormitories are needed. For this reason, Rainwater Harvesting (PAH) is applied as an alternative to providing clean water and as an effort to utilize rainwater. The rainwater that can be collected is influenced by the maximum daily rainfall using hydrological analysis. This hydrological analysis method aims to analyze the quantity of rainwater that can be accommodated through the roof of the TB 4 ITERA Dormitory. Rainfall data used in this plan is data from BMKG Radin Inten South Lampung. To get the rainfall calculated using the selected distribution, namely log Pearson type III and rain intensity using the mononobe method with PUH 5 years for 2 hours at 24.78 mm.day-1. From the rainfall, the dimensions of the gutter, standpipe, flat pipe, and roof washing pipe are 5 inches in size. Meanwhile, the volume of rain water that can be accommodated is 10,100 liters per day. Rainwater harvesting planning at the TB 4 ITERA hostel requires a fee of Rp. 65,532,800.00.Keywords: rainwater, boarding house, rainfall, hydrology

Abstract

Peat fire is one of the most environmental issues in Indonesia, particularly in the region of South Sumatra. The fires usually occur during the dry season from Juni to November. This study is designed to evaluate the impact of peat fires on changes in land cover in the Merang Kepahyang Peat Hydrological Region (MK-PHR) for the period of 2002 to 2015. The changes identified by the Normalized Difference Vegetation Index (NDVI) method using Landsat satellite imagery. The results of the study show that extreme peat fire associated with climate anomalies events occurred in 2006, 2012, and 2015. The largest peat fires during the observation period occurred in 2015 coincided with extreme climate anomalies generating negative changes in land cover in the most of MK-PHR areas. The changes occurred in almost half (49%) of the MK-PHR area, where it moved from the dense to moderate vegetation class. The spatial and temporal land cover changes will be discussed in more detail.

Abstract

Public open space or Urban open space as a means of outdoor activities are not only become part of the lifestyle but also the needs of the community especially for people who live in urban areas with a daily work routine. One of the public open spaces is the retention basin called Embung, where people carry out various activities both individually and in groups. Here, Institut Teknologi Sumatera (ITERA) as a state university located in South Lampung Regency Lampung Province has several Embungs from Embung A, B, C, D, E, and F. Embung A is the most frequently visit due to its position adjacent to the Terusan Ryacudu street that makes it easy to be accessed not only by ITERA academicians but also by surrounding communities in the morning and afternoon. However, this location which is close to a busy highway makes it potentially get negative impacts from transportation activities, one of which is air pollution. In this research aimed to determine the perceptions of the visitors about the ambient air quality in Embung A. Our research was carried out before the pandemic, more precisely in 2019. The results of the questionnaire found that most of the visitor consider the ambient air quality is in good condition (72%) with more than half of them (59% of the respondent) said that the Embung air quality were important. The statistical analysis results show a significant result (p-value=0.001 < 0.05) between perceptions of air quality with the duration of visits. In conclusion the Embung A visitors have a good perception of Embung’s ambient air quality and its importance. Further research is needed to better understand the motives behind the visit to Embung or other public open space and their relation to other environmental parameters.

Abstract

Rooms with pollutants have a poor impact of 2-5 times greater than outdoors. The lecture hall had the potential to experience a decrease in air quality. This study was conducted to assess microbiological air quality in the general lecture building I Institut Teknologi Sumatra, Lampung, Indonesia, during the COVID-19 pandemic and its relationship with environmental conditions. This study was conducted using a settling sampling technique to count the number of bacteria and fungi in the air. Samples were collected twice daily for five working days. The results showed that the highest concentrations of bacteria and fungi were found at the wifi corner location, at 36.7–1237.2 CFU/m3 and 225.4–1431.2 CFU/m3, respectively. The highest average concentrations of bacteria and fungi at the wifi corner location were found in the afternoon at 479.1 ± 438.1 CFU/m3 and 800 ± 548.4 CFU/m3, respectively. The three locations did not meet the standards of room suitability for humans with immunodeficiencies based on the ACGIH. The location of the wifi corner did not meet the standards of the Minister of Manpower of the Republic of Indonesia No. 5 of 2018 and the WHO regarding microbial standards in the room. The highest value of the Global Microbial Contamination Index (GIMC/m3) was found in the wifi corner (G4: ≥2000 – ≤4000), which is closely related to population density and ventilation. Environmental factors influence the density of bacteria and fungi at the sampling sites. The relative humidity strongly influenced the concentration of fungi. In addition to relative humidity, bacterial density is also affected by light intensity and the number of people. This indicates that despite restrictions on activities during the COVID-19 pandemic, the room at GKU 1 did not meet the eligibility requirements for students with immune disorders. Doi: 10.28991/CEJ-2023-09-01-09 Full Text: PDF
