Analisis Kelompok Kegiatan Masyarakat Sempadan Sungai dalam Hubungannya dengan Upaya Menjaga Kebersihan Sungai di Wilayah Kelurahan Sungai Lulut Kecamatan Banjarmasin Timur Kota Banjarmasin Provinsi Kalimantan Selatan

Mukhyar Amani — 2024-09-27

Sungai Lulut sub-district is one of the sub-districts within the East Banjarmasin sub-district, Banjarmasin City. Most of the daily activities of the river border communities in this sub-district consist of market and shop activities. It is thought that population density and the rise of trade activities can affect the cleanliness of rivers. At least two types of waste were found on the river border of Sungai Lulut Village, East Banjarmasin District, namely domestic waste and commercial waste. There are indications of a relationship between community activity groups and efforts to deal with waste and rubbish, thus showing their influence on community efforts to maintain river cleanliness. It is also indicated that the age and education level of the community are influencing factors, as can be seen from the student-level community groups whose involvement is relatively low in efforts to deal with waste to keep the river clean.

Analisis Beban Pencemar dan Kapasitas Asimilasi Sungai Klinter Nganjuk

Amelia Novita Kartikasari — 2024-09-27

Klinter River in Nganjuk is subjected to pollution loads from various pollution sources, including domestic and industrial waste. Water quality can affect the condition of Klinter River, which is still used by the local community to support daily activities. The parameters analyzed include TSS, COD, BOD, NO3-, NO2-, NH3, PO4, and oil and grease, taken from data provided by the Nganjuk Environmental Agency. The study aims to assess the carrying capacity of Klinter River by analyzing pollutant loads and the river's assimilative capacity. Regression analysis is conducted to obtain equations and graphs illustrating the relationship between pollutant concentration and assimilation capacity for each parameter. The analysis results indicate that COD, BOD, and NH₃ parameters are no longer able to undergo self-purification.

Komparasi Pengelolaan Sampah TPST Kartoharjo dan TPS 3R Payaman Terhadap Pengurangan Timbulan Sampah Kecamatan Nganjuk

The rapid economic growth correlated with population growth has resulted in increased activities and consumption by society, which in turn increases waste production. If waste continues to accumulate, it will certainly pollute the surrounding environment. In waste management in Nganjuk Regency, especially in the Nganjuk District area, there are TPST Kartoharjo and TPS 3R Payaman which manage waste with different systems. Waste generation in Nganjuk District is 2,577.73 tons per year. TPST Kartoharjo can process waste up to 97.20% while TPS 3R Payaman is 70.32%.

Analisis Pengaruh Faktor Meteorologi Terhadap Konsentrasi Gas SO2 dan NO2 dari Cerobong Ketel Pabrik Gula X

Mareta Fifianah — 2024-09-27

The process of burning bagasse in a steam boiler produces pollutants in the form of exhaust gas emissions through the chimney, which can pollute air quality and harm health. The aim of this study is to determine the great influence of meteorological factors including exhaust gas temperature, air temperature, and flow speed in 4 areas of the boiler pipe that can affect the load of SO2 and NO2 gas pollutants through statistical data analysis. The ANOVA test used in this study was the ANOVA One Way test. The results of the study showed that there was a significant influence of the air temperature factor on SO2 in Boiler 4 / Cheng Chen with a value of F value 14,553 and a sig value of 0,032, as well as the influence that exists on the exhaust gas temperature factor and air temperature on NO2 in Stork Boiler 2 with an F value of 15,358 ; 17,889 and a sig value of 0.030 ; 0.024. The results of the analysis can be used as monitoring to evaluate the success rate and operational efficiency of the boiler under the management that has been carried out.

Analisis Kualitas Air Embung Bendo, Mayangkawis dan Babo dengan Peruntukan Wisata dan Pertanian di Kabupaten Bojonegoro

With the potential of the agricultural sector, Bojonegoro Regency certainly requires an abundant supply of clean water. To overcome this problem, the Bojonegoro Regency Government built reservoirs to protect clean water supply in several areas in Bojonegoro Regency. The utilization of existing embung in Bojonegoro is not limited to agriculture only, but also as a tourist spot. To date, there has been no research assessing the quality of water in reservoirs. Consequently, this study aimed to evaluate the water quality in three reservoirs located in Bojonegoro. This study employs qualitative analysis derived from the environmental laboratory water quality assessments conducted by Dinas Lingkungan Hidup Kabupaten Bojonegoro. The findings from the water analyses of Embung Bendo, Embung Mayangkawis, and Embung Babo reveal distinct conditions among the three locations. These variations are attributed to differing environmental factors that influence each site uniquely.

Analisis Status Mutu Air Sungai Gandong Kecamatan Dander Kabupaten Bojonegoro Menggunakan Metode Indeks Pencemaran

Nuril Izzah — 2024-09-27

Sungai Gandong merupakan sungai yang melalui Kabupaten Bojonegoro dengan panjang 45 km. Salah satu sumber air Sungai Gandong berada di Sumber Air “Growgoland” Kecamatan Dander. Penelitian dilakukan untuk menelaah beberapa parameter kualitas air di 6 titik Sungai Gandong ruas Kecamatan Dander sehingga dapat diketahui kondisi dan tingkat status mutu airnya. Parameter yang dianalisis yaitu pH, DO, BOD, COD, TSS, dan nitrat. Status mutu air dianalisis dengan Metode Indeks Pencemaran (IP) yang berpedoman pada Keputusan Menteri Lingkungan Hidup No. 115 Tahun 2003 tentang Pedoman Penetapan Status Kualitas Air. Setelah dianalisis diperoleh Indeks Pencemaran (IP) ≤ 1 yang berarti sungai dalam kondisi baik. Nilai Indeks Pencemaran (Ip) terendah 0.527 di tiitk 0 dan tertinggi 0.907 di titik 3 Sungai Gandong.
