Abstract An environmental problem that often occurs during the rainy season is standing rainwater. Therefore, some water catchment areas are needed to reduce standing water that will minimize environmental damage instead. In densely populated urban areas the available space for water infiltration is very limited. Using biopore infiltration holes’ technology which uses organic waste to increase the rate of water infiltration into the soil can be an alternative solution. This study aims to determine the effectiveness of biopore infiltration holes with organic waste treatment to increase the rate of infiltration of soil. The methodology used in this study is the Horton test, in which biopore infiltration holes are using PVC pipes with various diameter 3 in, 4 in, and 5 in. The measurement of the infiltration rate observed by decrease in water level every interval of 5 min, 10 min, 15 min, 20 min, 25 min, and 30 min continually. The results show that the effectiveness of biopore infiltration holes using PVC pipe with a diameter of 3 in, 4 in and 5 in are increasing 62.92%, 70.60%, and 54.11% respectively.

Increasing and developing infrastructure in urban areas has resulted in decreased water infiltration quality into the ground. The increasing of settlement needs and raising its price has resulted in many water catchment areas changing their function unconsciously in urban areas. This condition was ultimately triggering the loss of opportunities for rainwater to into the ground. At present, when the rainy season arrives, almost all major cities in Indonesia experience flooding. The torrential rains that lasted just 1 hour were enough to cause relatively high inundation, which varied from 30 cm to over 1m. This study aims to analyze the intensity of rainfall and its impact on the potential for flooding in urban areas and how to overcome it by utilizing rooter system technology. The results showed that the 4-way rooter system technology's influence was considerable in reducing the water level. An experimental area of 100 m2 treated with a rooter system of 16 pipes with a water level of 40 cm can infiltrate stagnant water into the soil within 120 minutes. Meanwhile, in the same area without rooter technology, it takes 400 minutes to absorb water into the soil until the stagnant water is completely gone. This proves that the rooter system technology plays a significant role in accelerating water absorption into the ground, reducing the risk of flooding.

Abstrak. Kota Banda Aceh menjadi daya tarik bagi masyarakat sebagai sentral kegiatan pendidikan dan ekonomi, sehingga membawa pengaruh bertambahnya jumlah penduduk yang menyebabkan kebutuhan lahan semakin meningkat. Lahan yang sebelumnya berfungsi sebagai daerah resapan air tersebut mengalami konversi lahan yang menyebabkan berkurangnya daerah resapan air sehingga ketika terjadinya hujan dengan intensitas tinggi air hujan tidak secara maksimal terinfiltrasi ke dalam tanah dan terjadi penggenangan. Maka, diperlukan upaya untuk meresapkan air hujan yang efektif  ke dalam tanah dengan menggunakan lubang resapan biopori. Salah satu tempat yang ingin diketahui besarnya laju infiltrasi menggunakan lubang resapan biopori adalah di lima halaman rumah dengan luas bidang kedap yang berbeda. Penelitian ini bertujuan untuk mengetahui jumlah lubang biopori yang dibutuhkan di setiap rumah serta mengetahui jumlah volume air yang terinfiltrasi. Jumlah volume air yang terinfiltrasi pada rumah A yaitu 2,88 ml, pada rumah B yaitu 6,12 ml, pada rumah C yaitu 10,24 ml, pada rumah D yaitu 4,26 ml, pada rumah E yaitu 2,17 ml selama pengukuran. Jumlah ideal LRB yang dibutuhkan pada setiap halaman rumah A, B, C, D dan E berturut-turut adalah 82, 51, 27, 71, dan 230 lubang dengan intensitas hujan sebesar 6,62 cm/jam. Infiltration Rate of Absorption Holes Biopore Based on Type of Organic Material as Water and Soil Conservation Efforts Abstract.  Banda Aceh appeal to the public as the central economic and educational activities, this bringing the influence of growing population and increasing land needs. Increasing population it brings increased land requirements. Previous land serves as the water catchment area of land conversion experience leading to reduced water catchment areas. So, when it rains with high intensity of rain water, is not optimally infiltrated into the soil and flooding occurred. We need efforts are needed to effectively absorb rain water into the ground. One of the places to know the magnitude of infiltration using biopori absorption holes are in five broad areas of the home page with different impermeable. This study aims to determine the amount of absorption wells which are needed in every houses and to know the volume of water that infiltrated. The total volume of water that infiltrated the house of A is 2.88 ml, at the house of B is 6.12 ml, at the house of C is 10.24 ml, at the house of D is 4.26 ml, at the house of E is 2.17 ml for measurement. LRB ideal amount needed at every driveway A, B, C, D and E are respectively is 82, 51, 27, 71, 230 holes with rain intensity of 6.62 cm / hour.

Organic waste is the largest composition of waste generated by the people of Indonesia, which is around 50-60%. This type of waste, especially food waste, is easy to smell if it is stored for too long so that it has the potential to pollute the environment. On the other hand, organic waste has good nutrients that can be generated, including through BSF (Black Soldier Fly) maggot bioconversion treatment. The BSF maggot bioconversion method is a method of processing organic waste which is carried out by converting organic matter into other products that are useful and have added value by utilizing biological processes from microorganisms and enzymes. Organic waste treatment with this method is generally carried out on a community-based basis and is integrated with the development of agriculture, fisheries and animal husbandry, because maggot cultivation produces commodities of economic value such as compost and maggot larvae. Compost contains very good nutrients so that it can be used for organic farming and maggot contains high protein that can be used for animal feed and fisheries. The implementation of this program was piloted in the boarding school community, namely the Az-Zakaria Islamic Boarding School which is managed by the Az-Zakaria Islamic Education Foundation (YPI) in Sindangbarang Village, Jalaksana District, Kuningan Regency. The result of this implementation is the formation of a new group of entrepreneurs engaged in the cultivation and utilization of BSF maggots.

Population densities in cities of developing countries are much higher than in other parts of the world, and the predominance of poverty in urban slums is ubiquitous throughout the region. In many urban areas, the lack of wastewater and waste management continues to be a huge challenge for environment and health protection. Decentralized approaches are proposed to provide practical, alternative options for sustainable urban wastewater and waste management in urban conditions. Conventionally, on-site constructed brick/concrete biogas reactors are the most used models. However, long construction periods, quality issues and leakage of biogas are often the disadvantages of construction design. In contrast to these systems, prefabricated biogas reactors can be produced off-site from different kinds of material. In this paper, prefabricated biogas reactor and treatment systems will be discussed, which could be applied in different developing countries. Meanwhile, some existing cases in China, Indonesia and South Africa are presented to show clear scenarios.

Bioaerosol characterization represents a major challenge for the risk assessment and management of exposed people. One of the most important bioaerosol sources is the organic waste collection and treatment. This work analyzed and discussed the literature with the purpose of investigating the main techniques used nowadays for bioaerosol monitoring during organic waste treatment. The discussion includes an overview on the most efficient sampling, DNA extraction, and analysis methods, including both the cultural and the bio-molecular approach. Generally, an exhaustive biological risk assessment is not applied due to the organic waste heterogeneity, treatment complexity, and unknown aerosolized emission rate. However, the application of bio-molecular methods allows a better bioaerosol characterization, and it is desirable to be associated with standardized cultural methods. Risk assessment for organic waste workers generally includes the evaluation of the potential exposition to pathogens and opportunistic pathogens or to other microorganisms as biomarkers. In most cases, Saccharopolyspora rectivirgula, Legionella spp., Aspergillus spp., and Mycobacterium spp. are included. Future perspectives are focused on identifying common composting biomarkers, on investigating the causality process between chronic bioaerosol exposure and disease onset, and finally, on defining common exposure limits.

Developing countries face serious environmental, social and economic challenges in managing different types of organic waste. Proper treatment strategies should be adopted by solid waste management systems in order to address these concerns. Among all of the treatment options for organic waste, composting is the most approved method as an effective strategy to divert solid waste from landfills. This experimental research aimed to examine the potential of producing compost from source-separated municipal organic waste in Shiraz, Iran. Market waste (fruits and vegetables) and garden waste (plant residues) were used as the raw input materials. They were subjected to the windrow pile composting method in an open site area. The process was monitored against several physical, chemical and biological parameters. In-situ measurements (temperature and moisture content) were carried out on a daily basis. Sampling and lab analyses were conducted over the period of the biological treatment. The final product was of acceptable moisture and nutrient levels, pH, Electrical Conductivity (EC), and Carbon/Nitrogen ratio. All of the analyzed compost samples had lower concentrations of heavy metals than the Iranian and German standards. Overall, the results obtained revealed that composting is a promising method for municipal organic waste treatment. The findings also imply the effectiveness of the source-separation collection method in the production of high-quality compost.
