Treatment technology of sea water into freshwater is known as desalination. An effective and economical desalination technique is desalination with evaporation. Thisstudy aims to determine the effect of roofing materials on the amount of freshwater produced. The study was conducted using a miniature evaporative tub that had a rooflike shape. Evaporative tubs dimension was 1m x 1m x 0.02m of laminated wood material. 20 liters of brackish water was pumped into the tub. Water in the tub was then closed using a roof designed like a roof made of fiberglass and polycarbonate. Brackish water was left in contact with the sunlight for 24 hours. As a result of heat transfer from sunlight to evaporation tub, brackish water experienced evaporation. The steam moved upward and was captured by the roof wall then condensated resulting in fresh water. The conclusion obtained was a miniature roof of evaporative desalination using fiberglass material obtained 427 ml of fresh water while using polycarbonate material obtained 136 ml fresh water. Keywords: Roof, Desalination, Evaporation.

Phytoremediation is an alternative biological treatment that can be used to reduce soil or water pollutants. Phytoremediation has the advantage of environmentally friendly waste products and a lower budget compared to physical and chemical processes. In addition, phytoremediation has the weakness of long contaminant absorption times, and quite a few plants that are used as phytoremediation agents die because they are unable to survive the high concentrations of heavy metals contained in polluted media. This study aims to determine the ability of the S. javanica (S. javanica) plant as a phytoremediator for soil contaminated with the heavy metal Zn from industrial wastewater. Phytoremediation lasted for 10 days by contacting artificial Zn wastewater with a concentration of 5 mg/L and as much as 50 ml/day on the test plants. The planting medium used was 100% soil (A1) and 50% homogenized soil with 50% manure (A2). Tests were carried out on each part of the plant and growing medium with contact times of 0, 5, and 10 days of phytoremediation. The plant used as a phytoremediator is Sangitan (S. javanica). The optimum contact time in this study occurred on the 10th day of phytoremediation, and the addition of a 50% dose of organic matter in manure had an effect on the concentration of the heavy metal Zn. The accumulation of heavy metal Zn in plant leaves was greater than in roots, with an average BCF of 0.694 for leaves and 0.308 for roots. While the TF value > 1 represents that the Sangitan plant (S. javanica) has the potential to be a phytoremediator and has a high ability to translocate the heavy metal Zn.

Laundry waste is a pollutant that has pollutant parameters such as TSS and COD. One alternative processing is flocculation-coagulation using synthetic coagulants. The advantage of synthetic coagulants is that they are able to remove high concentrations of pollutants, but the disadvantages are that they produce quite a lot of chemical sludge and the pH of the water becomes acidic because the higher the concentration, the more coagulant is used. Previous research explains that chitosan at low doses has good penyisihan efficiency so that when combined with PAC it is hoped that it can increase penyisihan efficiency with less sludge. The purpose of this study was to determine the optimum dosage and composition for PAC and chitosan coagulant composites using the Jar Test. The Jar Test method for determining the optimum dose uses fast stirring at 140 rpm for 2 minutes and then slow stirring at 60 rpm for 15 minutes and settling for 30 minutes. Determination of the optimum dose by adding a coagulant composite of 300 ppm, 500 ppm, and 700 ppm and by varying the composition at each dose, namely 1:1, 1:3, and 3:1 between PAC-chitosan. The best conditions from the study obtained an optimum dose of 700 ppm and an optimum composition of 3:1 between PAC and chitosan resulting in COD and TSS penyisihan efficiencies of 70.04% and 90.82%.

KPSP Setia Kawan has two types of farms, namely conventional dairy farms and organic dairy farms. The research results show that in the milk production process of 1 kg of ECM (Energy Corrected Milk) which was delivered to the farm gate for 1 year, the total carbon footprint of milk produced by dairy farms in 2010 was 1.23 ± 0.04 kg CO2 Eq/kg ECM, 80% comes from on-farm activities. This research will apply the Life Cycle Assessment method with the CMLIA Baseline impact method. This method can be used to carry out impact assessments in the livestock sector so it is common for LCA studies in the dairy sector so it is most suitable for conducting comparative studies. It is hoped that with this research, animal husbandry can find out the effectiveness of implementing organic cattle farming in reducing environmental impacts compared to conventional cattle farming and help promote animal husbandry that prioritizes environmental aspects in the production and supporting processes.

The coriander cracker industries in Nganjuk City, commonly structured in Small Business scales are still implying conventional equipment in its production. High daily production volumes are resulting the large amounts of liquid waste containing pollutants exceeding Indonesia’s Threshold Value specifically in Chemical Oxygen Demand (COD) at 131.2 mg/L and Total Suspended Solids (TSS) at 203 mg/L. This condition causes serious environmental risks toward improper treatment. The biofilter system is one of wastewater treatment method with a simple and applicable way, applying a biological treatment approach utilizing microorganisms to reduce organic contaminants. This study aims to analyze the influence of media type on the removal efficiency of COD and TSS concentrations in coriander cracker industries’ wastewater using an aerobic biofilter system with the bioball and Kaldness K1 media. Performance testing of the aerobic biofilter demonstrated that the reactor with Kaldness K1 media achieved the highest removal efficiencies, eliminating 85.96% of COD and 95.01% of TSS by day 12. The study confirms that the Kaldnes K1 media's porous surface structure and high specific surface area enhance biofilm growth of microorganisms, thereby optimizing organic matter degradation processes.

Sandblasting waste from the blasting process of ship construction has a high potential to pollute the air and a negative impact to the environment or human health. Nowadays the sandblasting waste from the blasting process of the ship construction industry has not been well managed, Therefore, it is necessary to characterize sandblasting waste and to select and apply an appropriate sandblasting waste control device. Tests was carried out by taking particulate samples in the site with High Volume Air Sampler (HVAS) equipment followed by the Gravimetric method, Scanning Electron Microscopy (SEM) and Atomic Absorbtion Spectrophotometry (AAS). The gravimetric method was used to test the concentration of sandblasting waste with an average yield of 6,654.545 mg/m3. The particulate size obtained from SEM testing was 1.751 to 63.03 µm, testing with the AAS method to get the value of heavy metal content of Fe and Al on average of 1.6375 mg/m3 and 2.2925 mg/m3. Control technology that can use for sandblasting waste are Gravity Settling Chamber or Cyclone for preremoval and Bag Filter or Scrubber or Electrostatic Precipitator as an advance removal.Keywords: ships construction, Sandblasting and Particulate control technology

Greenhouse gas emissions from waste management contribute to climate change, including in higher education institutions. This study aimed to evaluate the potential for carbon emission mitigation from waste management at the Politeknik Perkapalan Negeri Surabaya campus through organic waste composting and inorganic waste recycling using a waste bank system. The application of solid waste generation measurement was combined with the Intergovernmental Panel Climate Change guidelines and SNI 3964:2025. A descriptive quantitative approach was employed, utilizing primary data on solid waste characteristics from selected campus buildings. Baseline emission estimates and mitigation scenarios were used, assuming partial implementation of the 3R program: organic waste composting and recycling. The results indicate that the waste management sector produces approximately 5.44 tons of CO₂ per year, and the proposed emission reductions could reduce emissions by approximately 63%. The findings of this study indicate that integrated waste management has significant potential for reducing carbon emissions and supporting the development of low-carbon campuses aligned with Sustainable Development Goals 12 and 13, despite the methodological limitations related to the assumptions of emission factors and the level of implementation
