Environmental Engginering Departement, Faculty of Landscape Architecture and Environmental Technology, Universitas Trisakti, Jakarta, Indonesia


Abstract

Cypermethrin is known as synthetic pyrethroid (SP) which works to interfere the nervous system with a molecular formula of C9H11Cl3NO3. The use of pyrethroid pesticides which tends to be high and continuous without regard to the rules of pest control can have a negative impact, that is decreasing environmental quality and decreasing biodiversity. Pollution degradation in the soil due to pesticide residues can be done biologically by doing remediation technology. One of the microorganisms that can degrade insecticide residues in the soil is bacteria. Thiobacillus sp. and Clostridium sp. are insensitive to cypermethrin which has been prove by no inhibition zone formed on a media that contained cypermethrin. Therefor this research the aim is to determine the growth response of bacterial culture using Thiobacillus sp. and Clostridium sp. as a bioremediation to remove the insecticide cypermethrin in liquid media. Optimization of environment conditions use temperature with a variation (°C) of 20-35 and concentration of cypermethrin with a variation (ppm) of 25-100. cypermethrin analysis using the Gas-Chromatography Mass Spectrometer (GC-MS). This research proves that the bacterium Thiobacillus sp. and Clostridium sp. capable of removing cypermethrin in liquid media reaching 81.6% occurs at optimum conditions at 32°C and optimum concentration of 50% ppm.

Abstract

Universitas Indonesia has a high diversity of animals, especially snakes and monitor lizards. The existence of snakes in the UI region is often found in areas with high civitas activity and cause conflicts with humans. This can be seen from the snake incident report data that is quite high from 2017 to 2019. To reduce the conflict, it is necessary to educate the community to raise awareness about the types and roles of snakes and monitor lizards in the ecosystem. Educational programs include conducting socialization, holding open classes about snakes, as well as training in handling snakes to the UI civitas. Based on the educational program that has been carried out, there has been a decrease in the number of snakes that have died as well as the demand for lizards catching in the range of 2017 to 2019. The most found snake is Southern Indonesian Spitting Cobra (Naja sputatrix).

Abstract

PP RI No. 41 1999 has been the only legitimate policy of national ambient air quality standard in Indonesia since more than 20 years ago. Most of standard for air quality parameters were set based on precautionary principle. It ratified other ambient air quality standards globally which is less representative from real conditions in Indonesia. Due to possibility of massive changes in national air quality conditions and various technological and non-technological factors driving them. The needs of national ambient air quality revision in Indonesia is raising. In addition, air quality as public value needs to be managed strategically by Indonesias government in order to provide basic need of society. More representative standard is a key for better monitoring and controlling ambient air quality in Indonesia. Hence, we proposed a critical mind map of integrated approach, air quality standardization principle, and brief process on how to reset national ambient air quality standard. It included the path role of public administrator, private administrator, and theorist in defining integrated framework of status quo and snap prediction. This mind map can be used as base of re-standardization ambient air quality in Indonesia. Furthermore, upcoming greater legitimate policy on this issue is gladly looked forward.

Abstract

Civitas activities in the campus environment both from lectures and other supporting activities can produce waste. The civitas lifestyle often influences the amount of waste produced, such as inefficient use of paper and disposable packaging. Civitas awareness related to the impact of the lifestyle on the waste generated needs to be increased to support a sustainable campus. Some ways that can be done are by conducting socialization, implementing regulations, and conducting waste sorting programs. Based on the efforts that have been made, the amount of waste generated in 2019 has decreased compared to 2018. This is influenced by the sustainable campus policies implemented at Universitas Indonesia which began to be applied at the end of 2018.

Faculty of Science and Technology, Universitas Islam Negeri Sultan Thaha Saifuddin, Jambi 36361, Indonesia


Abstract

Jambi province has 4 national parks namely Bukit Duabelas, Berbak Sembilang, Kerinci Seblat and Bukit Tigapuluh representing coastal ecosystems in the east to highland ecosystems in the west. The national park area is an ideal habitat for hundreds of flora and populations of endangered animals. Kerinci Seblat national park registered in the World Heritage Site as Cluster Mountainous Tropical Rainforest heritage Site of Sumatra. Based on various result of research that have been done, the community around the conservation area is unable to participate in the conservation program. The assumption that conservation impedes the economic development of the community increasing damage in the conservation area. Illegal logging, illegal mining, animal hunting, forest encroachment, road networks, forest fires and uncontrolled harvesting of forest products is a major problem. Damage to conservation area make knowledge about conservation benefits important to understand. The recommended solution is to teach conservation science in college, suistainable social and economic approaches to the community regarding the benefits of conservation.

Abstract

Coal is still a backbone of Indonesia to generate electricity. Of the 58,519 MW electricity produced, 61% comes from coal-fired power plants.
The need for coal is supplied by many mines in Indonesia, and in the process of obtaining it often causes an environmental problem, namely acid mine drainage (AMD) generation. In addition, coal-combustion ash in power plants also have the potential to cause environmental problems. To manage these two potential problems at once, AMD and coal-combustion ash generation, a study on the use ash as a cover for sulfidic coal-mine waste-rock was conducted.
The results of the geochemical static tests conducted on fly ash (FA), bottom ash (BA), and waste rock (PAF) showed that BA has a high Acid Neutralizing Capacity (ANC), which is 771.5 kg H2SO4 / ton, and in contrary, PAF has a Maximum Potential Acidity (MPA) of 260.71 kg H2SO4 / ton.
Based on these results, a free draining column test was then performed, to understand the long-term tendencies of leachate water quality characteristics drained from the column.
Leachate water quality test from the base material (FA, BA, FABA, PAF) for several wet-dry cycles show FA, BA, and FABA mixtures (with composition 1:1) showing an average pH value of 11.4, which means it has potential as a neutralizer. While PAF shows a consistently low pH average value of 2.51.
To find out the effectiveness of FA and BA as the encapsulating material of PAF, kinetic test was also carried out for the layering composition (from top to bottom) as FA-BA-PAF; BA-FA-PAF; and FABA-FABA-PAF.
The test results show that the composition of the BA-FA-PAF layer gives a better pH value compared to the other compositions, with an average pH value of 6.75. In the composition of the BA-FA-PAF layer, the BA layer will function as the dominant layer to stabilize the moisture of the underlying material (FA and PAF) which is dominated by clay. The swelling condition of clay can cover the space between pores so that the potency of sulphide minerals oxidation in PAF is lower.

Abstract

The University of Indonesia is committed to monitoring and evaluating environmental quality as part of its environmental quality monitoring and evaluation program. The University of Indonesia Depok Campus area has six lakes with names of Kenanga, Agathis, Mahoni, Puspa, Ulin, and Salam (KAMPUS), which are monitored by water quality every semester. Lake water quality data are generally only compared to regulations and provide information on parameters that have exceeded National environmental quality standards but do not provide information on the status of water quality. The Nemerow and Sumitomo’s Pollution Index is an index used to determine the level of pollution relative to permitted water quality parameters. Pollution Index (IP) is determined for an allotment, and then it can be developed for several allotments for all parts of a body of water or a portion of a river. Based on the assessment of water quality from measurement data from 2017 to 2019, it was found that Aghatis and Salam Lake have met quality standards with PI values of 0.74 and 0.7. Lake of Kenanga, Mahoni, Ulin and Puspa are lightly polluted with PI values of 4.48, 2.57, 3.19 and 4.25.

Abstract

The development of hydroponic vegetable production in coastal areas is faced with the constraints of irrigation water quality that has high NaCl. The purpose of this research is to study the interaction of NaCl concentration in the planting media and the concentration of silica extract of rice husk on the growth of lettuce plants. The study was conducted in April 2019-June 2019 at the screenhouse Palasari-Cibiru Bandung city with altitude + 800 m above sea level. This study used a factorial complete randomized design consisting of 2 factors with 3 replications. The first factor is the concentration of NaCl (n1 = 0 ppm, n2 = 1,460 ppm, n3 = 2920 ppm, n4 = 4380 ppm, and n5 5850 ppm) and the second factor is the concentration of silica extract of rice husk (s1 = 0 ml l-1, 30 ml l -1, and 45 ml L-1). Growth parameters observed were plant height, number of leaves, leaf area, root length, and plant fresh weight. The results showed that there was an independent effect on the concentration of NaCl on fresh plant weight. In the condition of saline media with a concentration of NaCl 1,460 ppm-2,920 ppm and the concentration of silica extract of rice husk, 30 ml l-1 lettuce plants can grow in good condition.

Abstract

This study aims to determine the efforts to overcome the death of fruit and improve the quality of siam oranges outside the season through the application of mycorrhizal inoculants and concentrations of auxin growth regulators. This experiment used a randomized block design with 2 factors. The first factor: mycorrhizal inoculant dose (0, 50, and 100 g/tree), while the second factor: auxin concentration (0, 50, 100, and 150 ppm/tree), repeated 3 times. The results showed that the interaction of mycorrhizal inoculant dose and auxin concentration did not significantly affect all observed variables. Dosage of mycorrhizal inoculant 100 g/tree can increase fruit production out of-season and the quality of conjoined citrus fruit, as reflected in the increasing number of fruits harvested per tree (152.27 fruits), weight per fruit (98.00 g), fruit harvest weight per tree (15.53 kg) and total dissolved solids (14.10%), or an increase of 44.21%; 11.89%; 57.87% and 21.03%, compared without mycorrhizal inoculants (108.58 pieces; 88.80 g; 10.57 kg and 11.65% brix). Concentration of 100 ppm auxins/tree can increase off-season production and the quality of conjoined citrus fruits, reflected in the higher number of fruits/trees harvested (165.22 fruits), fruit weight per tree (17.03 kg)), weight per fruit (99.50 g) and total dissolved solids (14.43%brix), compared without auxin, 112.11 sheets; 10.44 kg; 84.66 g; and 11.15% brix.

Abstract

This study aims to determine the feasibility of coagulation flocculation processing using Moringa oleifera seed powder (MOSP) and vertical sub surface flow constructed wetlands (VSSFCW) to process leachate landfill (LL). The method used is to do a jar test to determine the optimum conditions and then proceed with VSSFCW processing. In the coagulation flocculation process, the optimum conditions were obtained with a dose of 175 mg/L, pH 6.5 and a speed of rapid mixing of 100 rpm for 10 minutes. This optimum condition is able to reach the percentage of COD, turbidity and Mn removal of 35.27%, 69.48%, and 94.83%, respectively. However, the effluent value is still above the Minister of Environment regulation standard No. 5/2014 regarding the standard quality of wastewater for the parameters of COD and Mn that is equal to 584.19 mg/L for COD and 6.98 mg/L for Mn, while for turbidity meets the standard of 69.83 mg/L. Further processing with VSSFCWs can improve the quality of LL effluent resulting from coagulation flocculation 66.36 mg/L; 4.97 mg/L for turbidity and 0.12 mg/L for Mn or with efficiencies of 88.64%, 92.88% and 98.22%. These results were obtained at the optimum HRT conditions for 10 days.

Abstract

Fipronil is one of the organochlorine pesticide that is persistent in the environment. Fipronil can be removed biologically by using bioremediation that utilizes the activity of microorganisms. This study aims to remove fipronil in Stone Mineral Salt solution (SMSs) media using Pseudomonas aeruginosa and Brevibacterium sp. with temperature and fipronil concentration as independent variables. Fipronil removal is carried out at a temperature of 20 - 45°C with a concentration of fipronil 20 - 70 mg/L. Based on the Gas Chromatography-Mass Spectrometry (GC-MS) test, optimum fipronil removal was obtained at 30°C for seven days with 40 mg/L of fipronil concentration. This shows that Pseudomonas aeruginosa and Brevibacterium sp. can remove fipronil with an efficiency of 90%, so this research can be continued to find out other physical parameters that affect fipronil removal in liquid media

Abstract

The Gross Domestic Product (GDP) becomes an important focus on measuring the level of public welfare. One of the sectors contributing to Indonesias GDP in the agricultural sector in the livestock sub-sector products. Indonesia is a country that is able to contribute from the livestock sub-sector to meet the food needs of the community at large. However, a classic problem arises in accessing capital and sales of livestock products, which makes the contribution of the livestock sub-sector fluctuate every year so that Indonesia must import livestock products to meet public demand. The development of crowdfunding-based financial technology as a breeder capital strategy through capital contributions supported by the integration of livestock partners and millennial farms planning with academics and practitioners. Through innovations based on the digitalization of financing and marketing of livestock products and supported by a positive trend of internet growth which is a separate opportunity to encourage increased access to livestock. TernAkses is an investment service innovation and sale and purchase of livestock products that connect investors who have excess capital to farmers who need capital with the support of online and offline-based marketing. The services provided by TernAkses support the creation of a system of solving livestock problems from upstream to downstream, through funding programs, partnerships, training, assistance, marketing, and livestock sharing. TernAkses uses a service base in the form of websites and android applications that can be accessed through a broad range of community smartphones. In its application, the synergy of related stakeholders is needed to be able to implement the concept of the Access Approach.

Abstract

Security is a basic factor in sustainable development at both national and regional levels. The security factor is also an important factor in investment, so it is not surprising for regions with a high level of security coupled with high investment. Indonesia as a large country spread over 34 provinces, the level of security of each region also varies, but there are still many areas that have a high crime rate. Various factors that trigger high crime include high poverty, unemployment, education, and lifestyle. For this reason, an effective and efficient formula for enhancing peace, public order, and community protection starts from the lowest level, namely Village. The model used is Sikades, a security model based on the empowerment of criminals, recedivisers, village thugs and unemployed who have been empowered to become Village Civil Service Police Personnel (From Zero to Hero) and integrated with online-based applications that help personnel and the community to give and receive reports on the current security situation in all villages in the district. thus providing a sense of security and comfort for the community.
