Akumulasi gas karbon monoksida yang memenuhi udara ambien dapat menyebabkan pencemaran udara. Aloha merupakan salah satu kawasan di Kabupaten Sidoarjo yang memiliki intensitas tinggi terhadap penggunaan kendaraan bermotor. Penelitian ini bertujuan untuk menganalisis potensi pencemaran udara akibat gas karbon monoksida jika ditinjau dari baku mutu yang terdapat dalam Peraturan Pemerintah Republik Indonesia No 22 Tahun 2021. Penelitian ini menggunakan metode observasi secara langsung di lapangan dengan analisis hasil secara deskriptif. Konsentrasi karbon monoksida pada hari sabtu, minggu, dan senin rata rata telah melebihi baku mutu udara ambien. Nilai konsentrasi karbon monoksida terbesar selama pengukuran sebesar 24.049,1 μg/m³ terjadi saat hari senin, sedangkan nilai terkecil yang didapatkan sebesar 8.016,4 μg/m³ terjadi di semua hari pada beberapa titik sampel diwaktu yang berbeda. Nilai konsentrasi karbon monoksida di Kawasan Aloha Sidoarjo selama pengukuran, rata rata telah melebihi baku mutu udara ambien.

Padatnya penduduk di Kota Sidoarjo menyebabkan terkumpulnya sampah yang dapat menggenangi aliran Sungai Tambak Cemandi, yang dapat menyebabkan terganggunya ekosistem sungai tersebut. Dikarenakan ada permasalahan tersebut maka diperlukan pemantauan kualitas air salah satunya dengan cara biomonitoring. Tujuan penelitian ini adalah mengetahui kualitas air tercemar Sungai Tambak Cemandi berdasarkan parameter fisika dan kimia, mengetahui struktur komunitas makroinvertebrata yang terdapat di Sungai Tambak Cemandi, mengetahui korelasi struktur komunitas makroinvertebrata dengan kualitas air yang terdapat di Sungai Tambak Cemandi. Penelitian dilakukan di Sungai Tambak Cemandi di Desa Kalanganyar Kabupaten Sidoarjo. Sampling pengambilan air untuk uji parameter fisika kimia dilakukan dengan cara mengambil air di sisi kiri sungai dan kanan sungai, serta pengambilan sampling makroinvertebrata dilakukan di 3 titik. Hasil korelasi yang didapatkan yaitu pada keanekaragaman terdapat korelasi sedangkan pada keseragaman makroinvertebrata tidak terdapat korelasi dengan kualitas air di Sungai Tambak Cemandi.

As an integrated water system, watershed is influenced by the upstream conditions and the biophysical conditions of catchment areas areas which in many places are vulnerable to the threat of human disturbance. Hence, this study was aimed at assessing the patterns of land use on sedimentation rates at Cimanuk watershed, West Java. We calculated the sediment concentration, river debit and prediction of sedimentation rates based on regulation of the Minister of Forestry No. P. 61/Menhut-II/2014. The study revealed that land use effect the sedimentation rates from agriculture, forestry, rice fields, settlement, sauce and soy sauce factory, and leather factory with the sedimentation rates are 2,86 ton/day; 58,73 ton/day; 33,64 ton/day; 33,80 ton/day; 78,85 ton/day and 56.83 ton/day respectively.

Most of this energy is derived from non-renewable sources such as oil, natural gas, and coal. These trends will have a significant impact on energy depletion. One solution to overcome this problem is developing alternative energy resources to replace petroleum, such as bio-alcohol. The objective of this study was to analyze the potential of bio-alcohol production from organic waste, that is, banana peel. This research is experimental. Bio-alcohol was obtained through a fermentation process of 3 types of banana peels waste, including Raja banana (Musa acuminata×M. balbisiana) peel, Agung banana (Musa paradisiaca) peel, and Nangka banana (Musa acuminata×M. balbisiana) peel. Fermentation was conducted using variations of Saccharomyces cerevisiae of 1%, 3%, and 5% with a fermentation time of 5 days. All experiments were performed in duplicate. The results sho...

In Indonesia, these pollutants are the products of combustion from industrial areas and transportation sectors. The effect of air pollution on plant morphology and physiology has been studied. The effects of air pollution on plants are widely seen and damage all plants. This study analysed the effects of gaseous pollutant on vegetable crops, namely, lettuce (Lactuta sativa L) and cucumber (Cucumis sativus L). The objective of the research was to analyse the effects of exposure of gaseous pollutant on growth of lettuce (Lactuta sativa L) and cucumber (Cucumis sativus L) in term of both morphology and physiology; thus, from the research we can control vegetable crops from air pollution. Growth parameters include the number of leaves, plant height, fresh weight, dry weight, number of chlorophyll, and stomata index. This research was conducted on Padjadjaran Universit...

Pencemar udara telah terbukti berdampak negatif pada kesehatan manusia, tumbuhan dan lingkungan. Pencemar udara diketahui dihasilkan dari berbagai sektor antara lain sektor industri, permukiman, perkantoran, dan transportasi. Sektor pelayanan publik seperti Puskesmas merupakan sarana kesehatan yang memiliki peranan vital sebagai tempat pertama upaya penyembuhan penyakit. Maksud dari penelitian ini adalah untuk mengevaluasi kualitas udara di 3 lokasi Puskesmas di Kota Cimahi Provinsi Jawa Barat dengan tujuan adalah menguji parameter kualitas udara meliputi gas dan partikulat yakni nitrogen dioksida (NO2), sulfur dioksida (SO2), karbon monoksida (CO), oksidan (O3), dan partikulat (TSP) serta menganalisa tingkat pencemar udara di 3 lokasi Puskesmas di Kota Cimahi Provinsi Jaw...

This study evaluated air quality in three Settlements near the LCHC in Cimahi City, West Java Province, among others were: settlements in Cimahi Selatan, Cimahi Tengah and Cimahi Utara Districts. The air quality parameters were Nitrogen Dioxide (NO2), Sulfur Dioxide (SO2), Carbon Monoxide (CO), Ozone (O3), and Total Suspended Particulate (TSP) at three Locations of the Settlement. Air Quality Evaluation results indicate that all gaseous parameters were below air quality standards based on Government Law No.41 Year 1999 about Air Pollution Control, but Total Suspended Particulate (TSP) concentration in settlements of Cimahi Tengah and Cimahi Selatan Districts have exceeded the standard. However the lowest gaseous concentration was found in Settlement of Ci...
