Reducing Aerial Environmental
BurdenBANDUNG CITY-INDONESIA
By Ayu Sukenjah

Climate Change in Bandung
Climate Change has influenced the livelihood in Bandung. Withover 2,4 Million peoples live in Bandung and the population still
growth for over 0,46% a year, Environment and Nature Source
Capacities was significantly pressing by populations mean andneeds.
As the City with the highest populations density in West Java,
Climate Change gives additional pressing and unique boundary
to City Government to seek up solutions and managing the CityPolicies.
We know that solid waste problems, mass transportation, landuse issue are common problems to every growing and moderncity but the effect of Climate Change make those common
issues were not simply to solve as usual problems.
As example, Bandung Center aerial which designed and build incolonial era have been develop as area of free of flood andpuddle even if a hundred year periodically rain has fall, butwhen the city infrastructure must face the climate change which
cooperate with usual city problems the facts say that The City
Must Change too or people will suffer and City will drown in
unsolve misery.

City Growth and Its Impact
Bandung aerial were design in 1920 to accommodate 100.000 people
and exceed

to 2,4 million in 2014 and still on going growth, thiscondition cause major problems and impacts for people andgovernment either to environmental capacities. Those Impact are :• Land Use Issue;• High Density populations and dispread public facilities;• Nature Source Crisis like fresh/under ground water supply;• Lack of Green Open Space;• etc.

Aerial Environment Burden
To solve Climate Change Effects trough Mitigations andAdaptations Acts in growing and high density populations city
are not implementing easily.
There are some Aerial Environment Burdens that been
identified in Municipal Bandung which is :a. Leak of Green Opening Space;b. The amount of rain absorption area drastically incline;c. Under ground water quantity reducing and Surface waterlevel decreasing;d. Temporary flood and puddles area spreading in highdensity community;e. Water Crisis.

How to Reduce Aerial Environmental Burden
Government of Municipal Bandung, Environmental Communities
Representative and Private Companies were sitting together
sharing ideas and try to find some fast track breakthrough tosolve the environment burden and climate change impacts anddeliver some of this acts and massive movements that been
expecting as the cure of our city problems.
There are :1. A Million Biopori Rain Absorption Hole Movement;
2. Massive Development of Shallow well (targeted to 100.000
at year of 2019);
3. Increasing the pecentage of Open Green Space from lessthan 13% to 23% of Bandung Aerial at year of 2019;

The Acts
A. A Million Biopori Rain Absorption Hole (LRB) Movement
This Movement were initiated at the end 2013 by Major of Bandung
City. The basic ideas are simple and cheap technologies can give agreat effect when implemented massive and rapidly by all of cityelements like students, government officer, private employ, and etc.
Million Biopori LRB were targeting one million LRB’s Hole being deploy
in a week (20 Dec 2013 to 25 Dec 2013) and had been succeed build
267.734 holes in 30 districts, 141 sub-district and being build by over
50.000 volunteers. This Movement continued as regular act and now
near 400.000 LBR holes were deploy in every office, public place,residential, private company, military and police base and many more.

Biopori Rain Absorption HoleThis simple and cheap technologies
being improved in Bogor by Mr. Kamir
R Brata and adopted by massive
movement by Citizen of Bandung Cityand right now being duplicate by moreof 20 Major Cities in all over Indonesia.

Biopori Rain Absorption Hole
Biopori Rain Absorption Hole Technologies have several benefit and easy
to implemented from early age student to senior citizen and had many
benefit which can help to solve several city problems, reducing
environmental burdens, and adaptation or both mitigation to climatechange effects .
Biopori Rain Absorption Hole Technologies could utilized for :a.
Absorb rainfall from wide to narrow aerial where typical drainage
system could not apply;b.
Reduce amount of puddle and temporary flood in relative shorttime because it can absorb puddle at least in size of 40 times from itdiameter;c.
Increasing water sub-surface deposit which being use by 80% of city
population as main fresh water source;d.
As first step of household solid waste reduction where about 20 %to 80% of organic waste could be proceed become compost in thishole;e.
Re-mediating biologic component in critical soil with lowest cost;f.
Preventing soil erosion and landslide;g.
As cheap composter unit which can handling about 3 to 6 liter oforganic waste daily;h.
Reducing Carbon Emitting.

B. Massive Development of Infiltration Wells
Infiltration Well with 3 Typical of Use were massively
develop in every district at Bandung in order to :1. Reducing run-off and infiltrating rain water into sub
surface deposit water line;
2. Recharging Aquifer;
3. Reducing flood and water puddle;
4. Preventing Land subsidence;
5. Water Deposit in dry season;
Bandung City have regulation about obligation to build
one of these 3 type of well depending on building
function and business type for every building permits
applicant.

Infiltration Well
There are 3 types of Infiltration Well which deployed in Bandung as Regulation
Mandatory :a.
Shallow Infiltration Well :This type of well have dimension of 1 m x 12-36 m which use for infiltrating rainwater from rain harvesting area and large water puddle to sub-surface waterdeposit line, pre treatment tank/unit must be imply to handling low risk
contaminant before rain water infiltrated to well.
b. Deep Infiltration Well:
This Well utilize by underground water consumer as obligation for conservations
aquifer and water resources where it dimension depending on the depth oftapping level from every permit holders.
c.
Flood Infiltration Well:
This kind of Well are the cheapest type of well among those 3 type of well, withdimensions of 1 m x 1m x 2 m, this well build in narrow resident, public places
and numerous sites all over Bandung Aerial as the preliminary flood controls
infrastructure which can reduce the burden of drainage system.

There are about 420 Well Type A, 200 Well Type B and over 22.000 Well Type C werebuild in all districts in Municipal Bandung From 2002 to 2014 at least 8.774 Wells of 3
type of Well were build from mid 2013 to mid 2014.

C. Increasing Percentage of Open Green Spaces
Due to National Regulation about ideal and affectivity of Green Open Spaces, every city inIndonesia require about 30% of it aerial becoming Green Open Spaces (20% public & 10 %Private).
This condition rarely can achieved by main city where high density population exist andspreading in all over area.
Bandung City have less than 13% of green open space at 2013 and targeting 10% addition in 5
years through several programs which establish by city stakeholder.
The Program are :a.
Repairing and utilizing over 100 existing city parks and build a new thematic park everymonth;b.
Build mobile park which can be deploy temporary in any open area;c.
Utilize private sleep land as public green open space;d.
Initiate regulation about obligation to Hotels and Mall Operator to have Roof Garden,Vertical Garden and increase trees planting and provide green open space;e.
Initiate and socialize urban garden and farming movement in rural area;f.
Utilizing and remediate critical and erosion land by implemented LBR technology andoptimilize trees planting in city street;g.
Regulating green building standardization to new and existing buildings and push land use
efficiency to new investor which appellant to building permits.
