Lokadewatanews.com – Online Media Coverage Team related to the chopping and processing method, Dr. Ir I Gusti Ngurah Nitya Santhiarsa, MT Dr I Gusti Agung AIit Suryawati, SSos, MSi Ir Ni M Dwidiani, MASc Prof. Dr. Tjok Tirta Nindhia, ST, MT said Garbage is a material mainly in the form of solids, comes from various materials of various characteristics, mainly organic and inorganic, some are ordinary and some are B3, and some come from domestic and some are processed by factories, while at Puri Gerenceng Pemecutan Bali. Monday (31/8).
According to I Gusti Ngurah Nitya Santhiarsa, Garbage is a material that the owner no longer needs or the residue of production and consumption or use is then discarded (with the hope that someone else will handle it or own it).
Besides that. In fact, garbage is a problem, a big problem for all city residents. For the owner, this material has no economic value or has very little economic value.
I Gusti Ngurah Nitya Santhiarsa said, So the key word, waste is a collection of material that is no longer needed by the owner. There are two main things about waste, namely the type of waste and the volume of waste, there are two types of waste in general, namely organic waste, consisting of material derived from living things such as animal waste and leaf pieces, and inorganic waste, the material from the remains of processed inorganic objects such as plastics, metals and ceramics.
Then the volume of waste, is the amount of waste in volume units (m3), which is the surface area covered by the garbage multiplied by the height of the pile of garbage. These two things are often discussed when the problem of waste is discussed, and solutions are found to solve them. “Said I Gusti Ngurah Nitya Santhiarsa.
One of the effective ways to overcome the waste problem in the city is to build a paradigm of waste is money or gold, or waste is a high economic value item, or the problem turns into a blessing. How waste becomes a necessity, How to turn waste into gold, The answer is the same.
Meanwhile, all waste in the area of Denpasar City The volume of waste in Denpasar City is around 600-800 tons / day / radarbali. Jawapos./read/2019/12/26), and if there are holidays such as Galungan and Kuningan, and if there is a big festival, it will increase by around 40 96 from the normal volume. Most of the waste comes from domestic and market activities, so most of it is organic waste, “he concluded.
In addition, in general, waste handling in big cities uses the role of the Environment and Sanitation Service (DLHK) and the private sector through the Waste Bank. The Waste Bank plays a more role in the zone hum waste production, namely in Banjar or housing, and DLHK plays a more role in the downstream zone of waste production, namely at TPS and TPA.
Both parties have worked hard enough, however, because the volume of waste is so large and continues to increase. so the work results are felt to be not optimal, this can be seen that there is still a pile of garbage in the TPS, especially at the TPA.
The waste problem is a ‘Time Bomb’ problem. If it is not resolved, then the garbage that has accumulated in the TPA will catch fire and explode (due to the high methane gas content).
So, when compared to other big cities, Denpasar City has actually implemented the 4R method, with REUSE, use RETURN, REDUCE, reduce consumption, RECYCLE, recycle or process again, and REPlACE, replace it with natural materials, with low yields. .
Meanwhile, what is not yet is the method of destroying and burning with an INCENERATOR, where the combustion heat becomes a heating boiler to drive an electric generator turbine and the ash from the combustion is used as a structural construction material, this type of investment is expensive and requires high expertise. Is there another way that is moderate, that is, the cost is moderate and the results are quite optimal, I think the method above is a paradigm change.
The paradigm or perspective of waste is gold based on the principle of circulation or cycle or process cycle or circle, a principle based on the natural cycle of life components in the earth, such as the water cycle, time cycle, seasonal cycle and so on.
Meanwhile, cyclic motion is the main motion of life. motion from nature, where the result of this cycle is the creation of balance and harmony. The principle of circulation in handling waste. “Said. IGusti Ngurah Nitya Santhiarsa, (Team).
