Abstract

Sugihmanik Village in Grobogan Regency, Central Java, has many people who work as tofu producers. However, this village is experiencing an environmental management crisis, one of which is the management of sludge resulting from the liquid waste processing process at their wastewater treatment plant (IPAL). One of the proposed solutions is the use of tofu waste sludge as maggot feed, which can provide economic benefits and reduce environmental pollution. The Krida Manik Waste Bank is expected to be a pioneer in managing and utilizing tofu mud to feed maggots which can later be used as animal feed. This study uses a qualitative descriptive method where data is extracted as much as possible to obtain information regarding program management. The results of the activity show that there is potential for managing IPAL sludge using maggots. With the abundant potential of mud, people can use it as a renewable resource. However, capacity development and ongoing assistance need to be carried out to get maximum results.

Abstract

Organic waste can be used to make compost. One method of composting is by using Biopore Absorption Holes. Processing organic waste into compost can be done by adding local microorganisms (MOL) as bioactivators with varying MOL doses (0,25,50,175,100,125) % for every 5kg of food waste and vegetable waste categories. Composting process uses biopori absorption hole method with a depth of 80cm and diameter of 6 inches. MOL can be made from vegetable or fruit waste because the materials used are simple and easy to obtain. In the composting process, addition of MOL can increase the content of macro and micro nutrients. This research aims to determine the effect of reducing volume of compost and analyze the content of C, N, P, K, Fe, and Zn, from the composting process with different MOL doses and types of waste that have been determined. The research results showed that C, P, Fe and Zn tests had met the quality standards, while N and K tests had not met the quality standards. It can be concluded that the most effective activator dose is 25ml/L in food waste category because the compost produced meets the quality standards of SNI 19-7030-2004 concerning Compost Specifications from Organic Waste.

Abstract

Water pollution exacerbates global water crises by reducing freshwater availability and quality. Agricultural wastewater, containing pesticides, herbicides, fertilizers, and organic matter, can contaminate water bodies if untreated. This study optimizes electrocoagulation (EC) parameters—voltage, time, and calcium concentration—to maximize nitrogen compound removal using response surface methodology (RSM). Results show a nitrate reduction of 88.37% (2.960 mg/L) at 45 V, 15 minutes, and 7 mg/L calcium, while ammonia was reduced by 99.37% (0.016 mg/L) at 30 V, 1.5 minutes, and 4.5 mg/L calcium. Calcium enhances coagulation by forming calcium hydroxide. The optimal conditions for nitrate and ammonia removal (3.709 mg/L and 1.338 mg/L) were 45 V, 15 minutes, and 5.09 mg/L calcium. EC also removed 96.73% of iron, with magnesium concentrations remaining very low (0.001 mg/L).

Abstract

Salamanmloyo, one of the sub-districts in West Semarang District, Semarang City, is a densely populated area with nearly all of its land built-up. Due to its location in the lower region of Semarang, it is vulnerable to flooding. Salamanmloyo has experienced floods and inundation due to insufficient pervious areas and inefficient drainage channels. This occurs when there is an imbalance between the drainage channel capacity and the discharge that needs to be handled, as well as when waste, sediment, and vegetation are present in the channel. As for the existing conditions in the Salamanmloyo Sub-district, no previous study regarding flooding and inundation has been conducted in this area. Therefore, it is necessary to conduct research and planning to determine the existing conditions of drainage channels, hydraulic and hydrological analysis results, and suitable SUDS types to decrease the flooding volume level. Hydraulic and hydrological analyses will be performed as a part of this planning, after which EPA SWMM 5.1 modelling will be performed under four different conditions: current, maximum SUDS application, channel normalization, and channel re-design conditions. The outcomes of the SUDS planning were applied in the form of 497 units of infiltration wells and 16,345.6 m2 of permeable pavement. SUDS implementation, drainage channel normalization, and redesign helped minimize the total flooding volume by 66.3%, from 231,456 m3 to 78,008 m3.

Abstract

The phenomena that often occur in the Cirasea Sub-DAS are floods in the rainy season and droughts in the dry season. Climate change, land use changes, population growth and industrialization have put significant pressure on the availability of water resources in the Cirasea Sub-DAS. The purpose of this study is to gain a better understanding of water resources and their management in the area. The research method used in this study is descriptive with a quantitative approach. Water availability is calculated using the HEC-HMS simulation and water needs are calculated using the formula approach published by the Ministry of Environment, 2014. A comprehensive analysis of water availability and the risk of water scarcity is assessed using HEC-HMS. Calibration and validation are also carried out to determine the suitability between field discharge data (measured) and the calculation results using HEC-HMS (calculated). The calculation results of the mainstay discharge of the Upper Citarum River referring to SNI 6738-2015, obtained the mainstay discharge of the Upper Citarum River Q80 of 2.3 m3/second, Q90 of 1.52 m3/second and Q95 of 1.1 m3/second. This research can provide a significant contribution in optimizing the carrying capacity and management of water resources in the Cirasea Sub-DAS area. The results can also be used to help determine strategies and planning for future water resource management.

Abstract

Dam construction offers substantial benefits to society, including the raw water supply. However, such projects also exert significant impacts on water quality and the surrounding ecosystems. This study aims to examine changes in water quality and their subsequent effects on the local ecosystem, as well as to propose appropriate mitigation strategies. The methodology employed includes the measurement of physico-chemical water parameters and biodiversity surveys. A case study was conducted at the Pamukkulu Dam by comparing water quality conditions at two sites (the upstream and downstream) before and after construction. The findings reveal a deterioration in water quality attributable to sediment accumulation, eutrophication, and alterations to natural habitats and local biodiversity within one year following impoundment. Notably, BOD levels downstream increased from 1.07 mg/L to 6.18 mg/L, while COD levels rose from 7.04 mg/L to 105.68 mg/L. Ammonia concentrations downstream increased from <0.001 mg/L to 1.09 mg/L, and total coliform counts escalated from 11 MPN/100 mL to 2,800 MPN/100 mL. Furthermore, oil and fat levels downstream rose from <0.02 mg/L to 0.19 mg/L, and MBAS levels increased from <0.01 mg/L to 0.01 mg/L. This study concludes that dam construction significantly affects water quality and ecosystems, particularly within the reservoir and downstream river areas.
