Abstract

A community service program was held in Surakarta city, in a boarding school named Kanzus Sholawat to solve the cooking oil waste problem. The used oil which locally is alluded to jelantah oil, blackish brown colored, contains exceptionally high levels of cholesterol, carcinogen, and it may cause harm for human wellbeing. Jelantah oil ordinarily will be directly thrown to the environment, hence may cause water and soil contamination. Agreeing to this, it is essential to teach individuals to do minimization and reuse to the utilized oil (jelantah). Besides, the individuals will be prepared to commercialize the items as a souvenir gift item. The jelantah oil will be processed into handwash cleanser products with a feasible, simple, and cheap procedure and utilizing effortlessly obtained material. To start, a 500 ml of used cooking oil is filtered and mixed with 160 grams of NaOH flakes soluted in 200 ml of water. Some drops of fragrance is added to make the soap perfumed. The purpose of this community service is to provide assistance to the Kanzus Sholawat Surakarta Foundation to take the economic value from the oil waste by commercializing the recycle product. The program will be carried out by training and education to handle the jelantah oil into handwash cleanser, and persistent assessment to make sure the Kanzus Sholawat Surakarta students and adjacent community get the optimal benefits. Pre-order sale system using e-commerce is also expected to be implemented by the students, to make this program sustainable.

Abstract

As a company engaged in transportation services, the airport located in East Java Province produces liquid waste with a quite large discharge in a day, which is 1120 m3. To treat the wastewater, the company has a Sewage Treatment Plant (STP) to adjust its quality standards before being discharged into the river. Every WWTP has the potential to cause environmental impact, both from the processing process and from the operation supporting tools. This study aims to analyze the three largest environmental impacts resulting from wastewater treatment activities at the airport in East Java, which are the impacts of Aquatic Ecotoxicity, Non-Renewable, and Ionizing Radiation. In addition, the author also provides recommendations for alternative STP operations that are more environmentally friendly. The approach used is the Life Cycle Assessment method using the OpenLCA application with the IMPACT 2002+ method.

Abstract

The problem of domestic wastewater originating from restaurants is the largest contributor to organic wastewater in urban waters. Among them are waste water parameters, namely oil, and grease. Oils and grease are compounds that do not dissolve easily in water. However, it can be dissolved with non-polar organic solvents. The carbon chains of oils and grease are also long. So, it is difficult to decompose and takes a long time if processing uses the help of microorganisms. So, the alternative is to use physical-chemical processing. In this research, we tried using a static mixer and an impeller mixer. We conducted a systematic review of DAF techniques in wastewater treatment. We reviewed six indexed databases namely dissolved air flotation, microbubbles, wastewater treatment, and key operational and design parameters involved in the effectiveness of the flotation process. In this pre-treatment, the focus is on the withdrawal/discharge speed in collecting wastewater as a test and the effectiveness of mixing wastewater with coagulants and air pressure. These three aspects are used in equilibrium to achieve the optimum dose for the static mixer use scheme. Meanwhile, the impeller mixer scheme uses rotational speed in mixing with the coagulant, contact time, and Reynolds number to achieve the required turbulence. Apart from that, the use of electrical energy in the pump is also calculated in these two schemes. The results obtained were the amount of weight of oil and grease collected in the static mixer pretreatment of 9.12% w/v and the impeller mixer of 7.63% w/v and the results of the organic content of the Chemical Oxygen Demand (COD) parameter for the static mixer were 86.92 % and mixer impeller 78.86 %. From these results, static mixers have advantages over using impeller mixers in terms of the effectiveness of the oil and grease reduction process.

Abstract

The airport in this study is one of the airports in East Java that uses an incinerator to process its waste. Emissions generated by the incinerator will disperse in the area surrounding one of the airports in East Java. With the increasing interest of the public in air travel, activity at the airport also increases. This increase also impacts the amount of waste processed by the incinerator and the emissions produced, including Sulfur Dioxide (SO2). The aim of this study is to analyze the dispersion of air pollutants using Aermod View modeling software with SO2 parameters from environmental document data of the airport from January to June and from July to December generated by the incinerator stack. The model produces isopleths representing the dispersion of SO2 emissions. The results of the SO2 model still meet ambient air quality standards, as indicated in Appendix VII of Government Regulation Number 22 of 2021.

Abstract

Waste water from the nickel mining process has the potential to contaminate the environment due to the presence of hazardous metals such as chromium (Cr) in the form of Cr(VI) and Cr(III), iron (Fe), nickel (Ni) and other heavy metals. These substances are of great concern because of their toxicity, which can have adverse effects on ecosystems and human health. This study was conducted to investigate the effects of UV-C lamp light intensity, contact time and RIPT-ZnO weight on the removal of hexavalent chromium (Cr(VI)) from nickel wastewater. The method used in this research involved immobilisation of photocatalysts on resin with RIPT concentrations of 5g, 10g and 15g and variations in UV-C lamp light intensity of 8W, 18W and direct sunlight. The contact times tested were 0 minutes, 30 minutes, 60 minutes, 120 minutes and 180 minutes, with the focus of the analysis on the Cr(VI) concentration. The results showed that increasing RIPT dosage resulted in higher Cr(VI) removal percentages. The highest Cr(VI) removal was achieved with a 15 gram RIPT dosage, especially when ZnO was used. The optimum contact time for maximum Cr(VI) removal was 180 minutes, indicating that the longer the wastewater is exposed to RIPT, the higher the removal rate. The study found that the use of ZnO in the RIPT technology achieved the highest Cr(VI) removal efficiency, reaching 96%.

Abstract

This study will optimize ZrCo as a catalyst applied to the surface of porous membranes to remove micropollutants, specifically ibuprofen. This method improves the reaction rate and accelerates the chain degradation of Ibuprofen, thereby preventing blockage caused by impurities in the membrane pores. The catalyst synthesis was performed using a hydrothermal method with ZrCl4 and CoCl2·6H2O as the primary materials. This method is employed to produce a high purity catalyst and yield a more stable catalyst. This research will measure the optimal catalyst through flux and removal efficiency during the membrane distillation process for 1 hour. Reaction conditions were adjusted using Air Gap Membrane Distillation at 80°C heating temperature, 4 L/min flow rate, and 1.5 mmol/L peroxymonosulfate as pre-oxidation. Experiments were conducted by comparing 9 types of catalysts, from which the best calcination temperature was selected for catalyst concentration optimization. Based on the flux and removal data tested statistically, the optimum catalyst type and calcination temperature were achieved at a 2:1 composition with a calcination temperature of 600°C, yielding flux and removal efficiency values of 7.0238 LMH and 98.53%. Meanwhile, the optimum catalyst concentration was obtained at 0.5 wt%, with flux and removal efficiency values of 8.05 LMH and 99.83%.

Abstract

Permasalahan sampah masih menjadi permasalahan umum di Indonesia dan menjadi konflik berkepanjangan. Peningkatan jumlah penduduk dan terbatasnya pengolahan sampah menyebabkan timbulan sampah terus menumpuk dan menyebabkan permasalahan lingkungan. Jenis sampah yang mendominasi di Tempat Pembuangan Akhir (TPA) yaitu sampah organik yang dihasilkan dari rumah tangga. Sampah organik berdampak buruk bagi kesehatan manusia apabila dibiarkan menumpuk dan membusuk. Sampah perlu dilakukan pemilahan untuk memudahkan pengolahan tiap jenis sampah. Salah satu pengolahan sampah organik yang dapat dilakukan yaitu dengan pembuatan eco enzyme. Eco enzyme merupakan hasil fermentasi bahan organik, sehingga sampah organik dapat digunakan sebagai bahan baku. Manfaat eco enzyme berguna bagi lingkungan karena dapat mengurangi timbulan sampah organik, dan dari proses fermentasinya menghasilkan gas O3 (ozon) yang dapat mengurangi gas rumah kaca. Eco enzyme juga dapat digunakan sebagai pupuk cair dan cairan pembersih. Kegiatan ini bertujuan untuk mengimplementasikan konsep penanganan sampah organik skala rumah tangga melalui pembuatan eco enzyme. Kegiatan dilakukan melalui sosialisasi pemilahan sampah dan pelatihan pembuatan eco enzyme. Hasil dari kegiatan ini memberikan dampak positif dimana masyarakat mengetahui pentingnya pemilahan sampah serta mengetahui cara mengolah dan memanfaatkan sampah organik yang dihasilkan rumah tangga.
