Abstract
The COVID 19 outbreak has brought many changes to the order of human life. One is affected that life in an urban area. The metropolitan area that is usually crowded with human activity changes drastically to the empty urban. This phenomenon happened because many cities apply the lockdown policy to reduce the spread of COVID-19. This lockdown policy reduces the activity of transportation and industry, causing changes in air quality in the urban area. This study aims to see how much the impact of lockdown policy on air quality in 4 major cities in Indonesia, which is: Jakarta, Medan, Balikpapan, and Makasar. The method that used in this research is using Remote Sensing data by extracting Sentinel Satellite Image data, which produces air quality data, namely data NO2 levels in the air, then comparing the distribution of NO2 in the air between the year 2019 and 2020, and comparing data NO2 concentration in each month in 2020. Form the result of the spatial analysis of Sentinel Image Satellite data, during the lockdown policy in the year 2020 was implemented, the NO2 level in Jakarta significantly changed positively, the NO2 levels in the air decreased compared to the year 2019. For cities outside Jakarta, there has been a decrease in NO2, but the change that occurred is not significant. From this research, it can be seen that the lockdown policy during COVID-19 has improved the air quality in major cities in Indonesia.

Published: October 2021

Abstract
One of the goals in the SDGs that a region must achieve is 100% sanitation access. Sanitation is considered to have a significant impact on the quality of public health, both in rural and urban areas. The city of Bandung as a city with a high-density level has a big challenge in resolving sanitation matters. Acceleration efforts are needed to improve sanitation access in the city of Bandung which is still low so that it can realize open defecation free (ODF) for every urban village in the city of Bandung. This paper aims to provide a logical framework in the form of efforts that can be made to increase ODF in the city of Bandung. By collecting secondary data, interviews and FGDs as well as the highest and best use approach, the results show that the most important thing is to encourage the community to realize the need for a septic tank through community based total sanitation triggering (STBM) activities, connecting household wastewater channels to PDAM Sewerage, construction of small and large-scale communal septic tanks / IPAL and construction of “Gendong” pipelines, especially those in riverbank areas.

Abstract
Environmental Sanitation is the health status of an environment which includes sewerage disposal facilities (include septic tank), waste disposal facilities, the provision of clean and drinking water, drainage. Environmental sanitation is requirements for a healthy environment. Sanitation of densely populated settlement in coastal area especially in Indonesia are mostly not in good condition. Sanitation conditions are closely related to public health. Sanitation that does not meet the requirements is the cause of environmental-based diseases like waterborne deseases, one of which is diarrhea. The purpose of this study is to identify the sanitation and public health conditions of people that living in densely populated settlements in the coastal areas of Kangkung sub-district, Bandar Lampung City. Surveys, observations, questionnaires and interviews were conducted to obtain the expected data in this study. The results of this study show that some sanitation conditions in densely populated coastal areas did not meet the requirements of good sanitation (based on SDGs) because the conditions of the houses are so tight that there are poor condition of drainage and the unavailability of waste disposal facilities. There are still The number of diarrhea and another deaseses was high. There are still have diarrhea cases in Kangkung even though they already have a good clean water supply. however, this may be related to the poor condition of garbage disposal and drainage in Kangkung.

Published: October 2021

AbstractStudies of a region’s growth can only be conducted thoroughly considering its position in a larger urban system. In this system a region interacts with another region resulting in a complex urban network. Inter-urban interactions manifest in various forms such as population migration, trade, or information exchange. This study shows that urban centrality based on its interactions differs from urban centrality based on size. These interactions can be seen from the intensity of urban functions based on labor as well as interactions that can be seen from the intent on movement. This research is aimed at explaining the centrality patterns of urban interaction in Indonesia as the first identification on the relationship of cities on the island of Sumatra based on gravity model on economy and passenger movement based. There is a positive relationship between transportation centrality and economic centrality in Sumatra Island. The highest centrality in Sumatra island can be found in the Medan Area and the lowest centrality in Bengkulu.

Abstract
As stated in the Sustainable Development Goals (SDGs), water and sanitation are basic human needs that must be met to support livelihoods. However, in many developing countries, the issue of inequality continues to be faced, especially in slum settlements. The research was conducted in an area of slum settlements, in Kaliawi Village, Bandar Lampung to reveal the accessibility of water and sanitation using questionnaires and observation. The output is mapped using a spatial analysis approach. Furthermore, crosstab is used to analyze the possibility of internal factors affecting the condition of infrastructure provision in each house. The results showed that a large number of houses do not have a water source, some houses do not have septic tanks, the existing drainage network is not connected, and areas are not served by garbage collection services. Occupation, education level, land ownership status, and physical condition of the house are related to access to clean water and sanitation available in each house.

Published: October 2021

Abstract
Big data is a huge collection of electronic data which is currently popular to be developed in various scientific fields, including the transportation sector. Several data categories that can be used for transportation infrastructure planning are real-time location/position and timestamp of road users. This technological sophistication addresses a very crucial transportation planning problem that has been faced for many years, that is the inaccurate and unrepresentative prediction of the Origin-Destination Matrix. Up to this point, the Origin-Destination Matrix has been obtained using conventional and unconventional methods. Data was collected through manual traffic counts survey and direct interview in the study area. This results in unreliable data and inadequate sampling rates, which are only able to cover 20% of the population. In addition, the application of these techniques is expensive, time-consuming, and require a lot of human resources. Therefore, this study tries to develop a model capable of predicting the origin and destination of mobility, which in this case is represented by the sub-district boundary as a zone. As a result, an Origin-Destination Matrix can be obtained with a high degree of accuracy. The case study used is Bandung city. In the future, this research is expected to become a milestone in elaborating a validated Origin-Destination Matrix estimation model that can be used in various areas.
Optimizing the Heterogeneous Fleet Vehicle Routing Problem with Time Window on Urban Last Mile Delivery
Authors: Ayu Talitha , Nahry  
Published: October 2021

Abstract
The growth of the e-commerce business in Indonesia during the COVID-19 pandemic has increased the demand for last mile delivery (LMD) services. LMD activities with a large frequency of trips can increase logistics operational costs if operational handling is not carried out optimally. Optimization of LMD distribution routes is applied as an operational handling and also as a solution to the vehicle routing problem (VRP). VRP is an important problem to consider in transportation modeling where an optimum route plan is desired to obtain the minimum cost. The purpose of this paper is to optimize the last mile delivery route using the Heterogeneous Fleet Vehicle Routing Problem with Time Window (HFVRP-TW) model in urban areas. The route optimization process is carried out by developing and applying the HFVRP-TW model using data from one of the express delivery companies in Jakarta, Indonesia, and then simulating and forming several operational scenarios. The results of the analysis show that the application of route optimization with variations in vehicle types reduced operating costs by an average of 58.46% - 65.98% compared to the existing conditions. Scenario evaluation is carried out to obtain the scenario with the lowest operational cost. The evaluation results show that the best scenario is a scenario that has the closest characteristics to existing conditions, where there is no change in the type of vehicle used and optimization is only applied to operational routes. However, several other scenarios using a variety of different vehicle types still resulted in a reduction in operating costs of more than 50%.

Abstract

Bacillus spp. are known as potential bacteria as biocontrol agent against fungal phytopathogen, such as Aspergillus niger. The Aspergillus niger can cause many problems, including in agriculture sector. Antagonist activity of 3 bacteria isolates Bacillus sp. KRG, KRT and LDR have been carried out against Aspergillus niger CP. Dual culture method for antagonist assay was performed using streak, disc, and pour plate technique. Result from the disc technique showed that there is no significant antagonist activity differences between all isolates KRG, KRT, and LDR (51.94 %, 61.24 %, and 54.53 %). The highest inhibition effect was shown clearly in pour plate technique with inhibition value almost 100 %. The LDR isolate was selected for further evaluation based on the physicochemical characters according to strong catalase activity and rapid fermentation. Antibiosis assay was performed in order to evaluate the antifungal compound produced by LDR isolate using agar and broth culture method. The filtrates from growth medium 7, 10 and 12 days fermentation were used for antibiosis assay against Asp. niger CP. The growth of Asp. niger CP was inhibited by 10- and 12-days filtrate fermentation in all the 2 methods used. The percentage of inhibition of isolates observed in agar culture were 84.41 % and 84.21 %. Biomass of Asp. niger CP reduced by 74.55 % and 85.54 %.
The effects of apple juice (Malus sylverstris-Mill) as a natural antioxidant on spermatozoa viability of Tor soro 24 hours postcryopreservation
Authors: Arief M Z , Anabella N A , Muhiardi I , Abinawanto  , Arifin O Z 
Published: October 2021

Abstract
The population of Tor soro in Indonesia continues to decline due to overfishing. In T. soro farming, the gonad maturity between males and females tends to be asynchronous. Thus, it is necessary to have a stock of milt that can be used at any time for fertilization of the eggs by cryopreservation. Cryopreservation can cause cell damage due to oxidative stress and can be reduced by the addition of antioxidants in the cryopreservation medium. Apple (Malus sylverstris-Mill) can act as an additional antioxidant to increase the chance of spermatozoa survival post-cryopreservation. This study aims to study the influence of adding various concentrations of apple juice (0 %, 10 %, 20 %, and 30 %) and determine which is most optimal in maintaining the viability of T. soro spermatozoa 24 hours post-cryopreservation with a 1:9 milt-diluent ratio. The mean viability of T. soro spermatozoa post-cryopreservation in 0 %, 10 %, 20 %, and 30 % concentrations are 12.01 ± 2.24 %, 8.10 ± 4.53 %, 53 ± 5.14 %, and 6.23 ± 4 % respectively. The results of the one-way ANOVA test showed that the apple juice in various concentrations did not affect the viability of T. soro spermatozoa 24 hours post-cryopreservation (P>0.5).

Published: October 2021

Abstract
The megathrust at the west part of Sumatera can produce a lot of earthquakes. Several earthquakes in Sumatera that occurred from 2004 to 2007 raised tsunami with various heights. The high tectonic activity in this area can trigger landslides in the ocean which may lead to tsunami. Therefore, research about seabed landslides needs to be done in this zone. The study identified the seabed geological structure from 2D seismic section in the east part of Siberut Island. The seismic section was generated from seismic processing of Seismic Line-05 (AA’). The seismic data were acquired using LIPI Baruna Jaya VIII research vessel on the Pre-Tsunami Investigation of Seismic Gap (PreTI-Gap) marine expedition in 2008. Seismic section interpretation shows the presence of backthrust on this seismic line. The bathymetry data from the Geospatial Information Agency and marine survey are used to make bathymetry map, bathymetry charts, and slope map. Analysis using 2D seismic section, bathymetry data, and slope map shows the steep zones at 3–5 km and at 15–16 km from the south west edge of Seismic Line-05 (AA’) with 180 m and 300 m bathymetry drop, respectively. These steep zones must be watched because they can trigger submarine landslides and tsunami.

Abstract
Travertine is a geothermal surface feature that forms by the deposition of carbonate from discharging supersaturated thermal bicarbonate fluid. This study was conducted to determine travertine rocks mineralogy found in Cisolok geothermal area, Sukabumi, West Java. Petrographic, diffraction, and elemental analysis were performed on several recent and paleo-travertine samples. The petrographic and diffraction method confirms the presence of calcite and microcrystalline. The paleo-travertine deposit showed a more diverse texture through chemical elemental analysis. The analysis showed that the abundance of calcite minerals and the absence of aragonite indicate the intermediate low temperature geothermal system in Cisolok.
