Abstract

This study was chiefly aimed at pursuing new biologically active secondary metabolites of microfungus species, Lecanicillium evansii, isolated from sponge Callyspongia sp collected from West Bali Sea, Indonesia. Sponges were collected by scuba diving. A tiny piece of sponge was inoculated on the surface of malt agar plates and incubated at 27 ºC. In order to get a pure mono-culture of the fungus, repeated sub-culturing onto fresh malt agar plates were performed. The collected fungi were maintained on malt agar plates using the Wickerham medium. Mass cultivation of the fungus L. evansii (10 L) was carried out in 30 erlenmeyer flasks in Wickerham medium. After 10 days incubation, without shaking under constant room temperature (20 ºC), fungal mycelium were separated from the culture broth. The mycelia were extracted with methanol and ethyl acetate was added to the media. Both methanol-added mycelia and ethyl acetate-added media were left overnight. Seven compounds were isolated from L. evansii. Those compounds comprised phenolic compounds (terphenylin, deoxyterphenylin, terprenin 2, terprenin epoxide), bipeptide (cyclo-tyrosylprolyl), and simple aromatic compounds (acetyl hydroxybenzamide, 4-hydroxybenzaldehyde). Detailed analysis by NMR and mass spectrometry enabled their identification to be new deoxyterphenylin, new terprenin 2, and new terprenin epoxide.

Abstract

Waste pollution into the Citarum River (main water source of Jatiluhur Reservoir) was dominated by the manufacturing industry sector (textile, chemical, metal, pharmaceutical). Industrial was the most common contributor to heavy metal waste. Heavy metal contamination into waters will cause any problems, one of which was the emergence of various diseases both short and long term. Based on the issues, the study of heavy metal contamination and also water quality parameter conditions in the Jatiluhur Reservoir was necessary. The heavy metals (Cu, Zn, Hg, Pb, Cd) contents were determined using the X-Ray Fluorescence (XRF) Spectrometry method (for sediment) and Atomic Absorption Spectrometry (AAS) method (for water). The other water quality parameters were analyzed using the methods from the Indonesian National Standard (SNI). Furthermore, the data were compared to the Canadian Sediment Quality Guidelines (for heavy metal in sediment) and water quality standards from Government Regulation of the Republic of Indonesia Number 82 of 2001 (Class 3) (for water quality parameters). Concerning the discussion, Jatiluhur Reservoir was divided into three zones i.e. the inlet area, main inundation area, and outlet area. Conditions in the sedimentary layer, mercury (Hg) have accumulated throughout the Jatiluhur Reservoir area with conditions exceeding the maximum limit, while Cu metal tends to accumulate in the inlet area with conditions exceeding the minimum limit. For other heavy metals, exceed the minimum limit at some locations, but more results were below that. Although all heavy metals have not been detected in water, this was a warning that the presence of heavy metals in sediments can potentially dissolve into the water, the most extreme thing that can happen was upwelling. If this happens, the heavy metals can be contained excessively in water, harmful to and possibly consumed by aquatic biota and human. Considering these conditions, the biota that was most likely to be exposed was benthic organisms. In general, the water quality parameters in Jatiluhur Reservoir meet the quality standards. Only ammonia that does not meet the quality standards for sensitive fish life, regarding the massively of aquaculture activity in this reservoir.

Abstract

Electronic equipment is produced to meet human needs, so this will also have a significant impact on increasing the rate of e-waste generation in landfills in almost all countries. One of the environmental pollution issues that are of concern throughout the world is the management of e-waste (e-waste). This is due to the rapid increase in the use of electronic products. Thus, the existence of electrical and electronic equipment becomes shorter and becomes obsolete. The absence of information related to the volume of e-waste generation and material flow is one of the problems of the Indonesian government in managing e-waste. Therefore, the purpose of this paper is to calculate e-waste and analyze material flow. The method used in this study is Material Flow Analysis (MFA). Furthermore, a survey of household and informal sector respondents was used. The questionnaire adopted from UNEP was modified and distributed to 400 households and 54 informal sectors in DKI Jakarta. The results show the total rate of generation of e-waste produced aaproximately 7713.42013 kg/year. Furthermore, it is necessary to develop several strategies in order to avoid negative impact. This research can be information in filling the data limitations and management of sustainable e-waste in DKI Jakarta.

Abstract

Sand mining activities in Pasir Sakti District, East Lampung Regency, have changed the landscape and the allotment of land around it. The former sand mining area now becomes large puddles that are not utilized. This study aimed to analyze the suitability of water quality in ex-sand mining areas for tilapia (Oreochromis niloticus) culture. Observations were carried out at three stations in January-October 2019. Water quality measurements were performed to check water depth, clarity, temperature, current, dissolved oxygen, pH, salinity, nitrate, phosphate, iron, sulfate, and phytoplankton density. Analysis of suitability for aquaculture was carried out using weighting and scoring methods. Based on the results of the suitability analysis, the scoring result of the sand mining land for O.niloticus culture was in the range of 64% -68%. This score is classified as marginally suitable. The parameters with low scores are clarity, dissolved oxygen, temperature, pH, ammonia, phosphate, and iron (Fe) concentration parameters. Meanwhile, salinity, nitrate, sulfate, and phytoplankton density indicate conditions that are suitable for aquaculture. Therefore, severe treatment is needed to improve water quality to make it ideal for O.niloticus culture.

Abstract

Growing number of Indonesian Batik SMEs has been started since UNESCO announced batik as world heritage from Indonesia in 2009. However, this condition also brings negative impact related to water pollution. Huge variety of dyestuff always has been a challenge in estimating total pollution load from this sector. This study aim to estimate pollution load of some key parameters (BOD5, COD and TSS) of wastewater generated by Batik SMEs in Trusmi cluster. By calculating pollution load factor per unit product (PLU) trough analyzing waste water quality and quantity in every step of batik making process and considering type of fabric (cotton and silk) and type of dyestuff (Naphtol and Indigosol) as variable, it can be concluded that the PLU factor for BOD5 and TSS is associated to the type of fabric, meanwhile COD parameter is associated to the type of dyes. By multiplying the PLU factor with total production capacity from all SMEs in Trusmi cluster, it can be estimated that the total pollution load range in Trusmi area for BOD is at 5,9 – 39,5 ton/year; COD at 112-426 ton/year; and TSS at 4,88-16,3 ton/year.Keywords: batik, SMEs cluster, pollution load factor, waste water

Abstract

The research was one part of oil spill contingency plan (OSCP) developed for Delta Mahakam area, where oil & gas exploration and exploitation linked with rich biodiversity supporting coastal community livelihood. Environmental sensitivity  analysis for OSCP only do two early stages of OSCP scope, which integrated with the dangers of coastal vulnerability. This analysis mapped environmental component from oil pollution become sensitivity rangking as an effort to support response development strategies and priorities for the coastal resources protection. The aims of this research were (1) to establish environment sensitivity rank and (2) to identify primary factor supporting the environmental sensitivity for OSCP in south Delta Mahakam area. The result of analysis showed environmenal sensitivity was 62.37% (517.52 km), its mean very high sensitivity. Then the high sensitivity criteria was 11.31% (94 km). The criteria of medium sensitivity was 11.92% (99 km). While for low sensitivity and very low sensitivity respectively were 1.78% (15 km) and 12.64% (105 km). Based on Principal Component Analysis (PCA), 36.01%  variability was explained by axis of factor 1. The others variability 18.53% and 13.93% were explained by axis of the factor 2 and factor 3. Axis of factor 1 for coastal exposure (EK), oil residence index (OR), coastal type (TP), and biological resources (SH) had a quite large linear combinations coefficient, amounted to 0.94 (EK&OR), 0.83 (TP) and 0.75 (SH). This indicated a very high contribution for environmental sensitivity OSCP level drafting. On axis of factor 2, the linear coeffisien combinations for the resource utilization of port (PL) was 0.83 and settlement (PM) was 0.85. Axis of factor 3 contributed 0.75 and 0.66 on migas platform (PO) and placement of passive fishing gear/catchment area (AT). However, the utilization of coastal resources for PL, PM, PO and AT were on axis of factor 2 and factor 3 had a considerable distance with its SI variable. This possible caused by each variable percentage distribution which the value was very minor ranged 0.001-0.52%, so its not representated coastal resources elements closeness with SI variable in the study area.Keywords: Environmental Sensitivity, Oil Spill Contingency Plan, Mahakam Delta

Abstract

East Kalibaru River is one of the thirteen rivers flowing through Jakarta. East Kalibaru River has an important role in development of the region. Considering the increasing activities of people, settlements and number of industries along the East Kalibaru River, it is necessary to calculate contaminants load that discharged into the water body East Kalibaru. This study conducted to determine the point source and domestic waste pollution loads, using parameters of BOD, COD and TSS. The analysis showed that the total pollution loads such are calculated as 43.714 kg/day for BOD, 60.107 kg/day for COD and total 41.529 kg/day for TSS. Total pollution load discharged into river from point source effluent is amounted of 249 kg/day for BOD, 1.505 kg/day for COD and total 411 kg/day for TSS. Effect of domestic waste is very insignificant compared to the effect of point source that went into the river. The result suggest that approach that need to be done to reduce the burden of domestic waste water pollutants is by performing additional production or communal Wastewater Treatment Plant (WWTP) in densely populated areas.

Abstract

Wood industry produces a large amount of waste water that contains various pollutants. These pollutants are mostly dangerous for the environment. This research work aims to analyze the ability of phytoremediation for reducing pollutants in wood industrial waste water. These experiments usee Chrysopongon zizanoides L. and Ipomoea aquatica Forsk as phytoremediation agents. The ability was evaluated from the improved quality of wood industrial wastewater and the growth rate of C. zizanioides (L.) and I. aquatica Forsk in wood industrial wastewater. Analysis was conducted by measuring the removal efficiency of pollutants in wood industrial wastewater, the correlation between the reduced pollutants concentrations in the waste water and plant growth rate. Furthermore, a mathematical model is developed to predict the potential of C. zizanioides (L.) and I. aquatica Forsk for wood industrial wastewater. The result showed that C.zizanioides L. and I aquatica Forsk were potential phytoremediation agent. The removal efficiency for C.zizanioides L. and I aquatica Forsk are respectively as follows: 66.19% and 41.18%, TSS 58.51% and 45.38%, COD 70.07% and 40.37%, Total Amonia Nitrogen (TAN) 63.70% and 66.96%, NH3 96.16% and 88.79%, and PO43- 53.90% and 38.38%. Relative Growth Rate (RGR) of C. zizanioides (0.011±0.002 g/day) is better than I. aquatica Forsk (0.007±0.001 g/day). Daily Growth Rate (DGR) of C. zizanioides (0.019±0.003 cm/day) is better than I. aquatica Forsk (0.012±0.006 cm/day). TSS, COD, NH3, NO3-, and phenol have a negative correlation to plant growth (based on wet weight and root length). The developed mathematical models can be used to predict the phytoremediation potential of C. zizanioides (L.) and I. aquatica Forsk in degrading COD, TSS, and phenols of wood industrial waste.

Abstract

One of the ecological functions of mangroves ecosystem is to store carbon. Yet, on the other hand it also has the potential to cause greenhouse gas emissions through litter degradation even though its value is lower compared to the absorption value. Based on these two facts, mangrove management as a Green Open Space in the Tallo river area of ​​Makassar City needs to consider involving the participation of the community and the government as stakeholders. The research was conducted by desk work, literature study and respondent interviews regarding perceptions and participation in mangrove management. The results showed that the total uptake of mangrove carbon in the Tallo river in Makassar city was 351.02 tons CO2/ha, oxygen supply 255.29 O2-equivalent/ha, and the potential for global warming was 252.41 mg/ m2/hour consisting of 194, 33 mg/m2/hour of CO2 gas, 15.76 mg/m2/hour of CH4 gas, and 42.33 mg/m2/hour of N2O gas. The results of community perception and participation analysis show that around 89% of the community strongly agreed and supported the government in the effort to manage mangroves as a green open space. Based on this, the ecosystem in the Tallo river is very suitable to be managed for green open space as fresh air supplier and CO2 adsorber as well as a noise reduction from vehicle or industrial engines in Makassar city.
