Abstract

The increasing population every year and the rapid economic development in Semarang City caused environmental problems related to the water resources used. One of the impacts of environmental problems is the lowering water quality of the Banjir Kanal Timur (BKT) Watershed. The study aims to identify the potential and conditions of the BKT watershed, and river segmentation as a basis for determining representative monitoring points that are used to determine the capacity that is adjusted to the description of river water segmentation class. The methods were descriptive and quantitative analysis approach based on the observation and measurement in the field campaign as well as the laboratory analysis. In addition, this research was also compiling the QUAL2E modeling to determine estimation of contamination load and capacity of contamination of Banjir Kanal Timur. The results conducted that the BKT has poor water quality based on the parameters of DO, BOD, and fecal coliform, while for the NO3 and NO2 parameters indicate good water quality. Segment that has load capacity of BOD contamination is segment 1. Segments that have load capacity of Nitrite (NO2) and Nitrate (NO3) contents are segment 1 to segment 4. The segment which has load capacity of contamination of fecal coliform is segment 2. Thus, Segment 1 can be classified into second class while segment 2 goes into third class. Furthermore, segment 3 and 4 are into fourth class respectively.

Abstract

Groundwater is the valuable resources for supplying daily necessity of human’s life that is going to increase in line with the increasing number of population. Therefore, groundwater needs to be well managed. Groundwater management can be done thoroughly within a groundwater basin for defining groundwater recharge zone. The groundwater recharge zone was conducted by applying geospatial analysis using weighted and scoring approach. This method was accomplished by overlaying the score of some parameters (hydraulic conductivity, precipitation, soil cover, slope, and groundwater depth of water table) using ArcGIS 10.3 software. The parameters were permeability of rocks, rainfall, soil type, slope and depth of superficial groundwater level. The result of geospatial analysis can be divided into two zones which are groundwater recharge zone and groundwater discharge zone.

Abstract

Groundwater is the water resources necessary for living things and the most desirable human. Groundwater needs to increase as the population increase. One example is in the Alluvial Plain of Semarang. To supply water necessary, the population use a tap of aquifer shallow wells. Shallow aquifer vulnerable to contamination due to the effect of shallow depth and human activities. Therefore there is a needed to conduct for research on the groundwater vulnerability due to contamination. GOD is the system to determine of value groundwater vulnerability due to contamination. The parameters used are the type of aquifer (G), type of lithology aquitard (O), and the depth to groundwater table (D). These three parameters derived from resistivity data and hydrogeology data. The results of the analysis by this method has three levels of vulnerability of groundwater due to contamination the area of the vulnerability of low, moderate, and high. So it is recommended that the analysis can be made of the green open area to reduce contamination and groundwater catchment area is formed, and restrict the activities to achieve economic gains and reduce the danger of environmental contamination.

Abstract

Batik merupakan budaya Indonesia yang unik dan harus dilestarikan, tak hanya itu, batik juga telah ditetapkan sebagai warisan budaya dunia. Dalam proses produksi batik tersebut terdapat berbagai dampak negatif terhadap lingkungan yang diakibatkan oleh besarnya limbah cair yang dihasilkan, penggunaan zat pewarna sintesis, dan sebagainya. Hal tersebut juga terjadi pada Kampoeng Batik Kauman Pekalongan dalam memproduksi batik cap khas yang disebut batik encim. Kampoeng Batik Kauman Pekalongan merupakan kampung batik dengan jumlah Industri Kecil Menengah (IKM) yang cukup besar yaitu sekitar 30 IKM berpotensi untuk menimbulkan dampak lingkungan yang besar pula. Demi menghasilkan produk yang efisien secara ekonomi dan ekologi, perlu dilakukan analisis eko-efisiensi dan besarnya biaya dampak lingkungan yang diperlukan atau eco-cost terkait proses produksi dimulai dari awal produksi hingga akhir produk jadi. Pengukuran eko-efisiensi dilakukan menggunakan pendekatan Life Cycle Assessment (LCA). Pengukuran LCA dilakukan melalui perhitungan cost benefit analysis, eco-efficiency index, eco-cost value ratio, dan eco-efficiency ratio. Teknik pengambilan data dilakukan melalui wawancara dengan pengurus Omah Kreatif Kampoeng Batik Kauman Pekalongan, pemilik dan pekerja IKM di Kampoeng Batik Kauman Pekalongan untuk mengetahui hal-hal terkait proses produksi, input, output, dan biaya-biaya yang terkait pada proses produksi. Hasil penelitian menunjukkan nilai eco-cost Rp 69.937,365 untuk setiap lembar batik encim dan nilai eko-efisiensi 1,178 yang lebih dari 1 menandakan produk yang dihasilkan telah menguntungkan dalam aspek ekonomi dan juga sustainable. Hal tersebut menandakan bahwa Kampoeng Batik Kauman Pekalongan harus mempertahankan dan meningkatkan nilai eko-efisiensinya dengan melakukan perbaikan pada proses produksinya menjadi lebih efisien pada aspek ekonomi maupun ekologi.ABSTRACTBatik is a unique Indonesian culture and must be preserved, not only that, but batik has also been established as a world cultural heritage. However, the batik production process can cause various negative impacts on the environment caused by the amount of liquid waste produced, the use of synthetic dyes, etc. This also happened to Kampoeng Batik Kauman Pekalongan in producing its well-known batik cap called batik encim. Kampoeng Batik Kauman Pekalongan is a batik village with a fairly large number of Small and Medium-Sized Entrepreneurs (SMEs) which is around 30 IKM has the potential to cause a large environmental impact as well. For the sake of producing economically and ecologically efficient products, it is necessary to do an eco-efficiency analysis and the number of environmental impact costs required (eco-costs) related to the production process starting from the beginning of production to the end of each finished product. This eco-efficiency measurement is carried out using the Life Cycle Assessment (LCA) method. LCA measurement is performed through the calculation of cost benefit analysis, eco-efficiency index, eco-cost value ratio, and eco-efficiency ratio. The data collection technique was carried out through interviews with the management of Omah Kreatif Kampoeng Batik Kauman Pekalongan, owners and workers of IKM in Kampoeng Batik Kauman Pekalongan to find out things related to the production process, inputs, outputs, and costs related to the production process.The results showed the eco-cost value of Rp 69,937,365 was obtained for each encim batik and an eco-efficiency value of 1.178 which was more than 1 indicates that the product produced was profitable in economic terms and also sustainable. This indicates that Kampoeng Batik Kauman Pekalongan must maintain and increase its eco-efficiency value by making improvements in its production process to be more efficient in economic and ecological aspects.

Abstract

Many studies declared traditional oil mining in Wonocolo caused pollution, including river pollution.  During Covid-19 Pandemic, traditional oil mining in Wonocolo has been interrupted because world oil prices decreased. This made selling price of crude oil in Wonocolo declined. This made traditional oil mining decreased because oil wells were temporarily closed. The decrease in traditional oil mining might affect river water quality in Wonocolo. In a prior  study, the researcher had investigated water quality of Bungsu and Kragsaan River in Wonocolo, based on physicochemical parameters. The river had improved quality during Covid-19 Pandemic, seen from the decrease in the content of several chemical pollutants. Through this study, the researcher examined macrozoobentos community structure as a bio indicator of water quality, like assessing water quality of Bungsu and Kragsaan River based on biological indicators. This study used observation method by determining sample points purposively. Sample of macrozoobentos was analyzed using biodiversity index of Shannon-Wiener, species evennes index, and dominance index. Results of study showed Bungsu River had low biodiversity (H’ index 0.000 – 1.040), distressed community at B-1 and B-3 but stable at B-2, like high dominance at B-1 and B-3 but low at B-2. Kragsaan River also had low biodiversity (H’ index 0.000 – 1.010), unstable community at K-1 and K-3 like distressed at K-2, and low dominance at K-2 and K-3 but medium at K-1. Based on H’ index, Bungsu River was in the heavily polluted category at B-1 and B-3 and the medium polluted category at B-2. Meanwhile, Kragsaan River was in the heavily polluted category at K-1 and K-2 and the medium polluted category at K-3. This means although decreased levels of chemical pollutants at the sampling locations meant an increase in quality of water body, river ecosystem had not been able to rejuvenate condition during Covid-19 Pandemic.

Penelitian ini memiliki tujuan menganalisis kerentanan airtanah terhadap pencemaran secara spasial. Penilaian kerentanan airtanah terhadap kontaminan dapat diketahui dengan menggunakan metode DRASTIC. Metode DRASTIC merupakan metode pembobotan dari hasil berbagai macam parameter diantaranya yaitu : Kedalaman muka airtanah (D), Recharge (R), Media akuifer (A), Media tanah (S), Topography (T), Zona vadoze (I), dan Konduktivitas hidrolika (C). Dari hasil tumpeng tindih pembobotan setiap parameter, nantinya akan dijumlahkan untuk mendapatkan nilai rentang DRASTIC Indeks. Berdasarkan hasil analisis didapatkan rentang nilai DRASTIC Indeks (DI) dari 106-184 yang dibagi dalam empat tingakt kerentanan. Tingkat kerentanan sangat rendah memiliki nilai DI 106-120 dimana pada kerentanan sangat rendah memiliki sifat tidak memungkinkan terjadinya kontaminasi pencemaran. Daerah tingkat kerentanan rendah memiliki nilai DI 121-140 dimana pada tingkat kerentanan ini memiliki sifat dapat tercemar dengan intensitas kecil dikarenakan pembuangan sebagian kecil polutan yang dilakukan secara berkala.  Daerah tingkat kerentanan sedang memiliki nilai DI 141-150 dimana memiliki sifat dapat tercemar oleh sebagian polutan yang dibuang secara terus-menerus. Daerah tingkat kerentanan tinggi memiliki nilai DI 151-184 dimana pada tingkat pencemaran ini memiliki sifat dapat tercemar oleh semua polutan, kecuali memerlukan daya serap yang tinggi dan mudah berubah, dengan berbagai macam skenario.
