Abstract

The Siwalanpanji Water Treatment Plant with conventional and non-conventional processing has an impact on the environment due to the water treatment process. This study aims to identify potential impacts on the environment, analyze factors causing environmental impacts that arise, and provide recommendations for environmental impact management as an alternative plan for appropriate and environmentally friendly improvements using Life Cycle Assessment (LCA) which will be analyzed through Simapro software. LCA is an approach method used to identify and analyze environmental impacts resulting from all stages of the product life cycle so that it will be known which parts have the greatest impact on the environment. The three highest impacts that arise from the Impact 2002+ method are Respiratory inorganics, Global Warming, and Non-Renewable Energy. Factors causing these impacts come from the use of electricity and the provision of chemicals in the form of coagulants and disinfectants. Alternative improvements that can be given to reduce the impact that occurs include increasing equipment efficiency and substitution of Poly Aluminum Chloride coagulant with Aluminum Sulfate.

Abstract

The cement production process of the Tuban Cement Plant until the use of cement products goes through several processes, namely quarry (mining), raw mill, pre heater, kiln & cooler, finish mill, packaging, and distribution (land transportation and shipping). Based on the activities carried out in cement manufacturing, it could have an impact on the environment. Therefore, it is necessary to conduct research related to the process and end of the product using Life Cycle Assessment (LCA) analysis. The scope of this analysis uses a gate to grave approach with SimaPro software. The largest impact categories from the results of this analysis are inorganic respiration, climate change and fossil fuel. Alternative environmental management as an improvement program that can be carried out are optimizing the use of bag filter maintenance, reducing the use of coal as fuel and replacing it with derivative fuels (RDF) and using biodiesel as fuel for distribution trucks.

Abstract

The city of Kediri is one of the cities that received assistance from the SANIMAS program. All facilities built are communal toilets. This study aims to evaluate 5 Communal MCK Sanimas in Kediri City through two aspects. The first is the usability aspect where the data is processed using TCR with respondents coming from the user community, and the second is the sustainability aspect, where the data is processed using MDS Rapsanimas with respondents coming from experts related to Communal MCK Sanimas. The results of this study are from the aspect of usefulness, it says that Dandangan 1 gets a very good score, and the last one Balowerti gets a bad score. While the results of the MDS Rapsanimas get the final results of Dandangan 1 and Dandangan 2 the level of sustainability is good, and Ngadirejo's level of sustainability is less.

Abstract

The demand for cement in Indonesia in the last 10 years has increased by 63%. One of the raw materials for making cement is obtained from mining activities, namely limestone and clay. The method used in this research is Life Cycle Assessment. .Life cycle assessment is used to conduct an environmental impact assessment and using a cradle to gate approach. The data for each processing process is analyzed using SimaPro software. The biggest impact contribution from LCA analysis on the mining process is Fine particulate matter formation and global warming (Human Health). The suggested alternative improvement program is air control or pollutant control by reforesting and developing green open spaces around the cement industrial area of Tuban Regency

Abstract

Tuban Cement Plant could be a cement plant found in Tuban, East Java. This Cement Manufacturing plant produces cement made from Limestone, Clay, Press Sand, Silica Sand. The coming about item is around 2 million tons of cement. The cement generation forms analyzed incorporate the raw mill, clinkerzation and wrap up process forms. Within the handle of making the item, it does not as it were create the anticipated item but too makes by-products. Hence it is vital to do elective methodologies to diminish the burden of emanations coming about from the generation handle. Natural affect examination caused by the generation handle can utilize the Life Cycle Appraisal (LCA) strategy. In this examination employing a entryway to door approach with SimaPro 9.2.0.1. The affect examination strategy chosen is the Impact 2002+ this strategy may be a strategy that can get comes about that are in agreement with the goals and are close to the conditions that happen within the Tuban Cement Plant environment. The information analyzed in this consider employments generation information for each 1 ton of cement item.

Abstract

Limbah Laundry mengandung surfaktan (MBAS) dan fosfat (PO4) yang tinggi, fosfat berasal dari Sodium Tripoly Phosphate (STPP) yang merupakan salah satu bahan dalam deterjen. Untuk mengatasi permasalahan ini perlu adanya alternatif pengolahan dan pengaplikasian yang efektif untuk mengolah limbah ini, Salah satu alternatif pengolahan tersebut yaitu dengan metode elektro-koagulasi. Hasil penerapan aliran debit 0,5 liter/menit dalam proses Elektrokoagulasi kontinyu menghasilkan penyisihan Fosfat sebanyak 47,37 %, Surfaktan sebanyak 96,85 %, TSS sebanyak 78,38 %, COD sebanyak 86,98 % sedangkan jika dibandingkan dengan aliran debit 1 liter/menit didapatkan hasil penyisihan Fosfat sebanyak 45,32 %, Surfaktan sebanyak 96,44 %, TSS sebanyak 67,57 %, COD sebanyak 80,47 %.

Abstract

Kualitas air akan menurun seiring semakin jauhnya jarak distribusi dari instalasi pengolahan sehingga diberlakukan Permenkes No. 736 tahun 2010 yang mensyaratkan adanya kadar sisa klor sebesar 0,2 mg/l pada titik terjauh dari jaringan distribusi untuk menghindari adanya kontaminasi mikroorganisme. Penelitian ini menggunakan model dinamis VENSIM PLE untuk memberikan gambaran sederhana dan sistematis mengenai variabel-variabel yang mempengaruhi jaringan distribusi PDAM. Pada kondisi optimum untuk 12 hari menunjukkan kondisi yang cukup baik pada jarak 2 km dan 4 km jika ditinjau dari kualitas air berdasarkan parameter Escherichia coli dan sisa klor. Kebocoran pipa sangat berpengaruh karena menyebabkan masuknya senyawa organik maupun non-organik ke dalam jaringan distribusi. Selain itu, kebocoran pipa juga secara langsung dapat menyebabkan masuknya Escherichia coli yang berasal dari limbah domestik, utamanya tinja, di jaringan distribusi.

Abstract

Instalasi pengolahan air bersih Siwalanpanji dengan pengolahan secara konvensional maupun non konvensional memberikan dampak ke lingkungan akibat adanya proses pengolahan air bersih. Penelitian ini bertujuan mengidentifikasi potensi dampak yang ditimbulkan terhadap lingkungan, menganalisis faktor penyebab dampak lingkungan yang timbul, serta memberikanrekomendasi pengelolaan dampak lingkungan sebagai rencana alternatif perbaikan yang tepat dan ramah lingkungan menggunakan Life Cycle Assessment (LCA) yang akan dianalisis melalui software Simapro. LCA merupakan suatu metode pendekatan yang digunakan untuk mengidentifikasi dan menganalisis dampak lingkungan yang dihasilkan dari seluruh tahapan siklus hidup produk, sehingga akan diketahui bagian mana saja yang menimbulkan dampak terhadap lingkungan paling besar. Tiga dampak tertinggi yang muncul dari metode Impact 2002+ adalah Respiratory inorganics, Global Warming, dan Non-Renewable Energy. Faktor penyebab timbulnya dampak tersebut berasal dari adanya penggunaan listrik dan pemberian bahan kimia berupa koagulan dan disinfektan. Alternatif perbaikan yang dapat diberikan untuk mengurangi dampak yang terjadi antara lain dengan meningkatkan efisiensi peralatan dan substitusi koagulan Poly Aluminium Chloride dengan Aluminium Sulfate.
