Abstract

Abstract. The screen-printing process produces wastewater like organic compounds that are difficult to degrade and heavy metals such as chromium, copper, manganese, and lead, which are toxic and can accumulate in the human body through the food chain. Phytoremediation is one method that utilizes plants' ability to reduce organic and inorganic pollutants, including heavy metals. Objective: This study aimed to describe the concentration of screen-printing waste that can be tolerated by apu wood plants and analyze the effectiveness of apu wood as a heavy metal remediator. Technology or Method: The method used in this research is a combination of filtration and phytoremediation using apu wood to reduce heavy metals such as Pb and Cr,6+ and a preliminary test of Pb and Cr6+ contained in the screen-printing wastewater was carried out. Results: Apu wood lives and thrives on screen-printing wastewater, with an average of 34 new individuals' tillers growth within 15 days. The propagation of apu wood in screen-printing wastewater produced total biomass with an average of 145 grams per reactor. The effectiveness of apu wood as a remediator of Pb was 13.65%, and accumulated in the leaves was 0.0911 mg/L. The accumulation of Cr6+ in the leaves was 0.6635 mg/L. The Cr6+ component in the waste during 15 days of treatment did not show a positive effect on metal removal because the higher chromium element oxidation reaction occurred in the wastewater during the research process. Keywords Apu wood; chromium (VI); filtration; phytoremediation.

Abstract

Degradasi sampah plastik di pantai menghasilkan mikropartikel yang dibawa oleh arus air, gelombang dan pasang surut dalam sedimen pantai. Mikroplastik dengan rentang ukuran 0,3 - <5 mm terdeteksi di dua lokasi penelitian yaitu Pantai Pasir Panjang Kota Singkawang dan dan Pantai Batu Payung Kabupaten Bengkayang, Kalimantan Barat. Mengetahui bentuk dan kelimpahan mikroplastik di sedimen pantai menjadi tujuan utama dalam penelitian ini. Sebanyak 5 titik penelitian dalam satu lokasi, diambil sampel sedimen menggunakan transek berukuran 1x1 meter sebanyak 1 kg dengan memperhatikan faktor lingkungan untuk kemudian dilakukan analisis laboratorium. Kedua lokasi ini merupakan tempat wisata yang menjadi daya tarik pengunjung dan menjadi kegiatan para nelayan yang mampu menyumbang sisa buangan sampah cukup besar. Terdapat beberapa proses perlakuan sampel meliputi penyaringan, preparasi, penghancuran bahan organik, pemisahan densitas dan filtrasi. Teridentifikasi secara mikroskopik beberapa bentuk yaitu fiber, fragmen, foam, pellet dan film. Jumlah partikel mikroplastik paling banyak berada pada lokasi Pantai Batu Payung dengan rentang 173-344 partikel mikroplastik. Sedangkan kelimpahan tertinggi juga di Pantai Batu Payung yaitu 136,2 x102 partikel/gr. Tingginya kelimpahan mikroplastik berpengaruh pada sumber sampah yang dekat dengan lokasi pengambilan sampel, pasang surut air laut, kuat arus dan intensitas matahari tinggi.

Abstract

Ada beberapa aktivitas manusia yang dapat mencemari udara, salah satunya adalah kegiatan pengelolaan sampah yang ada di TPA. TPA Batu Layang merupakan tempat pemrosesan akhir sampah (TPA) di Kota Pontianak. Sampah yang telah tertimbun dalam jangka waktu tertentu akan mengalami proses dekomposisi yang menghasilkan beberapa gas pencemar, seperti H2S dan NH3. Penelitian ini bertujuan untuk menganalisis sebaran konsentrasi gas H2S dan NH3 di TPA Batu Layang Kota Pontianak yang divisualisasikan dalam bentuk peta menggunakan software ArcGIS 10.3 dengan metode IDW, serta untuk mengidentifikasi dampak gas H2S dan NH3 terhadap masyarakat di sekitar TPA Batu Layang Kota Pontianak yang dianalisis secara deskriptif menggunakan kuesioner. Pengukuran konsentrasi gas H2S dan NH3 dilakukan di empat area pada TPA Batu Layang yaitu, area kantor, area bongkar sampah, sel sampah D dan sel sampah E. Pengambilan sampel udara ambien menggunakan Impinger yang dilakukan sesuai SNI 19-7117.7-2005 untuk parameter H2S dan SNI 19.7119.1-2005 untuk parameter NH3. Pengambilan sampel dilakukan di tiga variasi waktu yaitu pagi, siang dan sore. Wawancara kuesioner dilakukan di dua Kelurahan di Pontianak Utara yaitu RT 05/RW 05 Kelurahan Batu Layang dan RT 01/RW 19 Kelurahan Siantan Hilir dengan masing-masing jumlah responden 17 orang tiap kelurahan. Hasil penelitian didapatkan konsentrasi rata-rata H2S melebihi baku mutu sedangkan NH3 berada di bawah baku mutu. Analisis sebaran konsentrasi gas H2S dengan nilai rata-rata tertinggi (berwarna merah) sebesar 0,255 ppm berada di area sel sampah d dan nilai rata-rata terendah (berwarna hijau) 0,051 ppm di area kantor. Sedangkan untuk gas NH3 nilai rata-rata tertinggi (berwarna merah) sebesar 0,543 ppm berada di area kantor dan nilai rata-rata terendah (berwarna hijau) 0,093 ppm di area sel sampah d. Hasil identifikasi dampak H2S dan NH3 terhadap masyarakat di sekitar TPA Batu Layang yaitu keluhan gangguan pernapasan dengan persentase batuk sebesar 100%, keluar dahak 85,3% dan mengi (napas berbunyi) 17,6%.

Abstract

Land and forest fires in West Kalimantan have been going on for a long time and in recent years it has gotten  worse with the increasing number of hotspots which has reduced visibility due to haze. This decrease in visibility reaches a considerable distance from the source of the forest fire. This condition has an impact on health problems, transportation, and population density. Bengkayang Regency was chosen as the location for the prototype site for the West Kalimantan nuclear power plant prototype which is planned to be built in 2024. The location that has been determined is Gosong Beach, Sungai Raya Islands District, with coordinates 108o 051'30” W – 108o 05' 23'' East and 00o 43 ' 50'' N – 00o 41' 15” South. This study aims to predict the distribution of PM10 due to forest fires at prospective site locations within a radius of 25 km based on hotspot point data during 2010–2020 using The American Meteorology Society Environmental Protection Agency Regulatory Model (AERMOD) method. The results showed that the number of hotspots around the location was 2,873 points in a period of 10 years. Four locations experience repeated events throughout the year within a radius of 25 km with the closest point as far as 5.34 km from the site location. Based on AERMOD modeling using 2020 meteorological data, the fastest possible distribution directly from the 4 points follows the south to west direction and does not go to the site location, but the closest distance to the site is 3.08 km.ABSTRAK Kebakaran lahan maupun hutan di Kalimantan Barat telah terjadi sejak lama dan beberapa tahun terakhir semakin parah dengan meningkatnya jumlah titik hotspot yang berdampak pada turunnya jarak pandang akibat kabut asap. Penurunan jarak pandang ini sampai pada jarak yang cukup jauh dari sumber terjadinya kebakaran hutan. Kondisi ini berdampak pada masalah kesehatan, transportasi, dan mobilitas penduduk. Kabupaten Bengkayang dipilih sebagai lokasi calon tapak prototipe Pembangkit Listrik Tenaga Nuklir (PLTN) Kalimantan Barat yang rencananya akan dibangun pada tahun 2024. Lokasi yang telah ditentukan adalah Pantai Gosong Kecamatan Sungai Raya Kepulauan, dengan koordinat 108o 051’30” BB – 108o 05’ 23’’ BT dan 00o 43’ 50’’ LU – 00 41’ 15”LS. Penelitian ini bertujuan untuk memprediksi sebaran PM10 akibat kebakaran hutan pada calon lokasi tapak pada radius 25 km berdasarkan data titik hotspot sepanjang tahun 2010-2020 dengan menggunakan metode The American Meteorology Society Environmental Protection Agency Regulatory Model (AERMOD). Hasil penelitian menunjukkan jumlah titik hotspot yang terdapat pada sekitar lokasi sebanyak 2.873 titik dalam kurun sepuluh tahun. Terdapat 4 lokasi yang mengalami kejadian yang berulang sepanjang tahun dalam radius 25 km dengan titik terdekat sejauh 5,34 km dari lokasi tapak. Berdasarkan pemodelan AERMOD yang menggunakan data meteorologi tahun 2020, arah sebaran asap dari 4 titik tersebut mengikuti arah Selatan menuju Barat dan tidak menuju lokasi tapak, akan tetapi panjang sebaran terdekat dengan tapak adalah sejauh 3,08 km dari rencana lokasi tapak

Abstract

This study used red mud as an adsorbent for biogas purification. However, red mud had to undergo dealumination and calcination processes before being used as an adsorbent. Several acids, including 1 M HCl and 1M H2SO4, were employed in the red mud dealumination process, which was then analysed by XRF and GSA instruments. The results show that the best type of acid for the dealumination process was HCl with a Si/Al ratio, total pore volume, surface area and pore radius of 1.697; 67,081 m2/g; 0.1624 cm3/g; 48.4242 Å. The biogas purification process was carried out using red mud adsorbent dealuminated with HCl by varying the length of the adsorbent column, such as 10, 20 and 30 cm, and the contact time of 5, 10, 15 and 20 min. The optimum column length variation was 30 cm. The results obtained for this variation were a decrease in CO2 content of 292742.30 ppm with an efficiency of 19.08%. The increase in CH4 was 378232.69 ppm with a percentage increase of 240.28%.

Abstract

Indoor air quality affects human health and productivity. The presence of microorganisms in indoor air is influenced by physical parameters of the space, activities within the space, building factors, ventilation systems, and human maintenance and care. This study aims to assess air quality and analyze the difference in the number of bacteria between minimarkets and the relationship test with their influencing factors. The study used a cross sectional method with 4 minimarket samples, 2 AC and 2 non-AC. Airborne bacterial colony counts were measured using a passive method with blood agar media, a contact time of 15 minutes, and 3 days of repetition. The average value of airborne bacterial colony counts in non-air-conditioned minimarkets (294.3 CFU/) was lower than in air-conditioned minimarkets (531.8 CFU/). The Rank Spearman correlation test results indicated that there was no significant relationship between airborne bacterial colony counts and temperature (p=0.498), humidity (p=0.089), light intensity (p=0.948), and visitor count (p=0.481). All studied minimarkets met the microbiological air quality, population density, and air circulation standards, but not all met the standards for room temperature, humidity, and light intensity based on the quality standards of the Indonesian Ministry of Health Number 1405/MENKES/SK/XI/2002.
