Abstract

The health service industry involves activities that provide medical services (hospital), manufacture of medical equipment or drugs, and medical insurance services. Options of research methods to measure the impact of services on environmental aspects are available. One among which is life cycle analysis (LCA), the recently popular practice in Indonesia. This paper attempts to explore whether LCA could be fitted to the health service industry. A literature review would help in procuring related references from various publications accompanied by several research results and related studies. For describing the application of LCA in hospitals, several articles were collected, which were later arranged according to certain systematics from several sources. The LCA methodology used here consists of the following four stages: goal and scope definition, life cycle inventory analysis, impact assessment, and interpretation. The stages follow the International Organization for Standardization (ISO) 14040 and UNEP SETAC, 2011. Several studies using the LCA method in hospitals have reported specific profiles such as the management of biohazardous medical waste (BMW) and waste water. Several studies have also used LCA methods to assess specifically the environmental and health impacts of a specific component of the hospital or hospital activities. For example, studies have assessed the impact of equipment used in the form of containers, catheter, laryngeal mask, gowns and also infrastructures’ facilities. The results of this study confirmed that the LCA method is suitable in health service industry, particularly in hospitals. Considering the merits and drawbacks involved in applying this method, one could further apply it to related health service issues.

Abstract

ABSTRACTWater treatment plants (WTPs) produces residues in the form of alum sludge during the treatment process. In Indonesia, due to various techno-economic constraints, some WTPs are not equipped by sludge treatment systems, so the generated alum sludge is discharged directly into water bodies without appropriate treatment. This condition may pollute water bodies because alum sludge contains various contaminants such as solid particles, organic compounds, inorganic metals, aluminum, and pathogenic microorganisms. This study aims to evaluate the characteristics of alum sludge from aspects of quality and quantity, which is indispensable for the design of sludge treatment facilities. Citayam WTP (capacity of 120 L/s) in Depok City was chosen as a case study. The study was conducted in several stages as follows: (i) survey and sampling; (ii) quality analysis of alum sludge; (iii) estimation of sludge generation; and (iv) mass and volume balance analysis. Results of comparative analysis of alum sludge quality against the Regulation of Minister of Environment of Indonesia 5/2014 shows alum sludge from flocculation units meets quality standards. In contrast, alum sludge from sedimentation and filter units were exceeded for TSS, COD, and Total Coliform parameters. Quantity-wise, the estimation of sludge generation by theoretical and empirical methods was found to be 1,898 kg/day and 4,854 kg/day. Analysis of mass and volume balance using STAN software indicates that the theoretical approach is quite representative, while the empirical method tends to be over-estimated.Keywords: alum sludge, sludge quality, sludge generation, water treatment plant, case studyABSTRAKInstalasi pengolahan air (IPA) dalam proses pengolahannya akan menghasilkan residu berupa lumpur alum. Di Indonesia, akibat berbagai kendala tekno-ekonomis, masih terdapat IPA yang belum memiliki sistem pengolahan lumpur alum sehingga langsung dibuang ke badan air tanpa pengolahan. Kondisi ini berpotensi mencemari badan air karena lumpur alum mengandung berbagai kontaminan seperti partikel padat, senyawa organik, inorganik, logam aluminium serta mikroorganisme patogen. Penelitian ini bertujuan untuk mengevaluasi karakteristik lumpur alum dari aspek kualitas dan kuantitas yang merupakan informasi penting dalam perancangan sistem pengolahan lumpur. IPA Citayam (Kapasitas 120 L/detik) di Kota Depok dipilih sebagai objek studi. Penelitian dilakukan dalam beberapa tahapan yakni survei dan sampling, analisis kualitas lumpur alum, estimasi timbulan lumpur, dan analisis neraca massa dan volume. Hasil perbandingan analisis kualitas lumpur alum terhadap PermenLH 5/2014 menunjukan lumpur alum dari unit flokulasi memenuhi baku mutu sedangkan lumpur alum dari unit sedimentasi dan filter melebihi baku mutu lingkungan untuk parameter TSS, COD dan Total Koliform. Dari aspek kuantitas, estimasi timbulan lumpur yang dilakukan dengan metode teoritik dan empirik berturut-turut sebesar 1.898 kg/hari dan 4.854 kg/hari. Analisis neraca massa dan volume menggunakan software STAN mengindikasikan bahwa metode teoritik cukup representatif, sedangkan perhitungan dengan metode empirik cenderung menjadi over-estimasi.Kata kunci: lumpur alum, kualitas lumpur, timbulan lumpur, instalasi pengolahan air, studi kasus

Abstract

The Citarum River is a strategic river in Indonesia, but has poor water quality.  The existing pollution control program has no impact on the river's water quality, because it uses a regulatory approach and prioritizes industrial sources. To improve the quality of the river, every pollutant source needs to reduce the pollution load discharged into the river based on the ability of the river to receive pollution. The purpose of this study was to measure pollution load allocation based on the total maximum daily load (TMDL) of the river. The results show that non-point sources contribute the highest pollution load (85%) compared with point sources (15%). The results of the measurement of pollution load allocation showed that the highest contribution of pollution load was from domestic waste (83.5%), followed by industrial waste (6.6%). The target of pollution load reduction for domestic sources is 81.8%, and for industries is 79.5%. The improvement of river water quality should be started at tributaries and domestic sources. This study can be used by local governments to develop water pollution control programs, for instance as a basis for determining the wastewater discharge permit of pollutant sources and permit trading.

Abstract

Public water supply company (PDAM) Rawa Lumbu is a water treatment plant which serves the needs of drinking water in Bekasi with a total production capacity of 260 L/sec. This total production capacity is divided into three smaller units. One of those is steel plate installation with a capacity of 2×100 L/sec, which was built in 2005. As one of drinking water provider, PDAM Rawa Lumbu is demanded to be able to provide safe drinking water that meets national water regulation PERMENKES 907/MENKES/SK/VII/2002. Method of evaluation consisted of 2 step activities. The first step was primary and secondary data collection, site/field observation and discussion with PDAM Rawa Lumbu management for determining existing condition and evaluation stages. The second step was evaluation on treatment plant efficiency in reducing raw water pollutans. Evaluation on the water treatment plant efficiency in reducing water impurities showed that Rawa Lumbu water treatment plant had a good turbidity removal efficiency of 97-99%. Besides, evaluation on unit process dimension with a current flow rate of 68 L/sec and designed flow rate of 100 L/sec, showed that it still had a good performance. However, it performed an actual maximum flow rate of 91 L/sec. The current reservoir can only accommodate a maximum flow rate of 106.41 L/sec.

Abstract

Cisadane River, Tangerang City, is one of the important rivers in Indonesia. This river is a source of raw water for PDAM Tangerang City and Soekarno-Hatta International Airport, but unfortunately the quality of this river water tends to decrease due to pollution. Many things have been done by the government in managing the river water, but have not brought positive changes to the raw water source. The problems that occur include urban development and changes in land use which have an influence on the burden of river pollution. The approach taken in this research is qualitative analysis and risk management. The final result of this research is the development of policies in the management of rivers as raw water sources, namely land use management, separation of drainage channels from domestic sewage, increasing the coverage of WWTP services, and strengthening institutional and regulatory aspects, especially in funding commitments.
