Logam berat Pb(II) merupakan jenis polutan yang menyebabkan pencemaran air serta berdampak terhadap kerusakan ekosistem. Limbah logam Pb(II) bersifat racun serta biomagnifikasi sehingga berdampak negatif terhadap kesehatan manusia. Kombinasi proses elektrokoagulasi dan adsorpsi merupakan salah satu alternatif yang efisien serta efektif dalam menghilangkan logam Pb(II) di dalam air limbah. Pada penelitian ini, proses pengolahan air limbah dilakukan secara batch menggunakan elektrokoagulasi dengan elektroda aluminium dan dilanjutkan dengan adsorpsi karbon aktif. Penelitian ini bertujuan menganalisis pengaruh tegangan elektrokoagulasi, waktu kontak adsorpsi, dan dosis adsorben terhadap penurunan konsentrasi Pb(II). Proses elektrokoagulasi dan adsorpsi menggunakan variasi tegangan (10, 20, 30 V), waktu adsorpsi (15, 30, 45 menit), serta dosis adsorben (2,5, 3,3, 4,1, 5 g/L). Hasil penelitian menunjukkan bahwa kombinasi elektrokoagulasi dan adsorpsi dapat menurunkan konsentrasi Pb(II) dalam air limbah secara signifikan. Peningkatan tegangan listrik, waktu adsorpsi, dan dosis adsorben menyebabkan meningkatnya efisiensi penyisihan Pb(II). Efisiensi penyisihan logam Pb(II) maksimal diperoleh pada kondisi tegangan 30 V, waktu adsorpsi 45 menit, serta dosis adsorben 5 g/L. Pada kondisi tersebut diperoleh efisiensi penyisihan Pb(II) sebesar 96,01%.

The fertilizer industry generally produces wastewater with relatively high ammonium and phosphate content, so processing is necessary so as not to cause eutrophication effects that harm the environment. Struvite precipitation with bittern media was an alternative method to remove struvite content in wastewater. This study aimed to analyze the effect of pH and molar ratio [Mg2+] : [NH4+] : [PO43-] on the struvite precipitation process in reducing the ammonium and phosphate content in the artificial wastewater of the fertilizer industry and to characterize the struvite obtained from the precipitation process. The precipitation process was conducted in batches with various pH and molar ratios [Mg2+]: [NH4+]: [PO43-]. The variation of pH used is 8−10. The molar ratios used are 1.5 : 1.0 : 1.0 and 3.0 : 1.0 : 1.0. Struvite characterization was conducted using SEM-EDX and XRD methods. The results showed that pH and molar ratio had an effect on the efficiency of removal ammonium and phosphate using struvite precipitation. The best pH value and molar ratio that can be used to remove content of ammonium and phosphate is at pH 9 with a molar ratio of [Mg2+] : [NH4+] : [PO43-] 3.0 : 1.0 : 1.0 which results in the removal efficiency of 86.50% and 99.96% respectively. The morphology of struvite obtained from precipitation is irregular rod-shaped with an average size of 28.53 μm. XRD results have detected peaks indicating the struvite phase.

Pembangkit Listrik Tenaga Uap (PLTU) Kabupaten Probolinggo sebagai industri pembangkit listrik tenaga uap berbahan bakar batubara menghasilkan beberapa parameter emisi dari proses industrinya, salah satunya Sulfur Dioksida (SO2). Emisi SO2 ini dikeluarkan melalui cerobong dimana nantinya akan menyebar ke kawasan sekitar plant. Emisi SO2 ini dapat berbahaya bagi kesehatan masyarakat dan lingkungan sekitar apabila Flue-Gas Desulfurization (FGD) sebagai instalasi pengendali emisi SO2 sedang bermasalah dan membutuhkan corrective maintenance. Oleh karena itu perlu dilakukan penelitian terkait analisis dispersi emisi SO2 agar dapat mengestimasikan dampak dari emisi tersebut terhadap lingkungan sekitar. Tujuan penelitian ini yaitu menganalisis dispersi emisi SO2 dari cerobong PLTU Kabupaten Probolinggo Unit 9 pada musim kemarau. Penelitian dilakukan dengan menggunakan data emisi pada periode pemantauan Bulan Juli – September 2019 dan data meteorologi pada periode pemantauan Januari 2018 – Mei 2020. Pada penelitian ini, Gaussian Dispersion Model dipilih untuk memodelkan dispersi emisi SO2. Software Surfer dan Google Earth digunakan untuk penggambaran pola dispersi emisi SO2. Hasil penelitian menunjukkan bahwa emisi SO2 terdispersi ke arah selatan dengan stabilitas atmosfer kelas B pada musim kemarau. Konsentrasi tertinggi emisi SO2 berdasarkan hasil model sebesar 107,74 μg/m3 dengan koordinat 7°43’43.452” LS; 113°34’17.766” BT dan memiliki jarak sebesar 1986,87 meter dari cerobong. Setelah sampai di titik maksimum, konsentrasi emisi terus menurun seiring dengan bertambahnya jarak dari cerobong.

Pembuangan air Limbah laundry secara langsung di aliran sungai menjadi penyebab tingginya pencemaran sungai. Air limbah laundry mengakibatkan peningkatan perameter COD, BOD5, serta MBAS sehingga berdampak negatif pada kehidupan ekosistem. Proses koagulasi menggunakan bahan kimia FeCl3 dapat menurunkan parameter COD, BOD5 dan MBAS dalam air limbah namun menimbulkan efek negatif pada kesehatan. Kitosan dari cangkang crustacea dapat digunakan sebagai alternatif koagulan yang ramah lingkungan. Kombinasi koagulan kitosan dan FeCl3 diharapkan mampu menurunkan parameter COD, BOD5 dan MBAS air limbah laundry serta dapat mengurangi dosis penggunaan koagulan kimia.Penelitian ini bertujuan mensintesa biokoagulan kitosan dari cangkang kepiting serta menguji efektivitas kitosan cangkang kepiting, ferri klorida, dan kombinasi kedua koagulan dalam pengolahan air limbah laundry. Proses deasetilasi cangkang kepiting menjadi kitosan menggunakan larutan NaOH 60% pada suhu 125oC selama 6 jam. Koagulasi dilakukan terhadap air limbah menggunakan tiga jenis koagulan yaitu ferrri klorida, kitosan, dan ferri klorida-kitosan. Hasil penelitian menunjukkan bahwa dosis optimum penggunaan koagulan kombinasi terjadi pada dosis 40 mg/L kitosan dan 100 mgl/L ferri klorida dengan menghasilkan efisiensi penyisihan COD, BOD5, dan MBAS masing-masing sebesar 71,67%, 81,14%, dan 66,24%. Penggunaan kombinasi koagulan pada dosis optimum dapat menghemat pemakaian ferri klorida sebesar 84%.

Waste glass bottles is an inorganic waste that amounts to 0.7 million tons per year with the main content of silica, so it can be used as the main ingredient to produce silica gel. In the soy sauce industry, glass bottle waste is generally produced from broken glass bottles during depalletizer activity, namely the activity of moving glass bottles to the glass bottle cleaning area. The glass bottle waste is generally only accommodated and has not been used optimally. This research aims to utilize waste glass bottles as a raw material for producing silica gel adsorbents using the hydrothermal method and the sol-gel approach. Silica gel becomes an adsorbent in the purification of bioethanol from wastewater washing dissolving tanks using the adsorption method. Variations in the bioethanol production are yeast weight as 0, 2, 5, and 8 g as well as fermentation time for 4, 7, and 10 days. The bioethanol purification process used variations in adsorption time for 40, 60, and 80 minutes. Characterization of silica gel using BET and SEM-EDX test. Bioethanol levels after going through the adsorption process were analyzed using the GC-MS method. The BET test results show that activated silica gel has a surface area of 231,851 m2/g. Analysis with SEM-EDX showed that activated silica gel particles were in the form of porous lumps with chemical content of Si and O elements of 40.94% and 51.92%, respectively. Based on the results of the GC-MS test, 60 minutes is the best adsorption time to increase the bioethanol content from 39,8 % to 72,0 %.

An increase in population will have a major impact on the environment, such as an increase in the volume of waste. The second largest composition of waste after food waste is plastic waste, which is a type of waste that is difficult to decompose. One of them is coffee packaging plastic waste. Recycling is a way that can be done to reduce coffee packaging plastic waste, namely by separating the plastic layer and the aluminum layer. The aluminum layer can be processed into alum. The purpose of this study is to separate the plastic layer and aluminum layer using the green solvent method using methanoic acid, the effect of variations in the concentration of KOH with a concentration of H2SO4 6M, and determining the optimum dose in reducing COD and BOD levels in wastewater tofu industry. The results showed that with the variation of the higher concentration of KOH, the yield of alum produced was also higher. Alum research results were compared with commercial alum. Comparison of these two types of alum shows that alum produced in this study resulted in higher COD and BOD removal efficiency than commercial alum, but with different coagulant doses.
