In the attempt to implement sustainable development, there is a definition that the use of natural source to keep it uses by the next generation well, both in quantity and quality. It needs to be supported by caring the environment both by the government and the community itself. The community awareness can be seen at its role on the management of domestic garbage. Several socio-economic factors such as age, sex, education, income, job, and the knowledge of environment have effect on community awareness in the management of domestic garbage. This study used logistic regression model which aimed at measuring to what extend the effect of the socio-economic factors to domestic garbage management in East Nusa Tenggara Province in 2013. It uses secondary data of Environmental Awareness Behaviour Survey that done in 2013 by the Central Agency on Statistics. The result of this study used α = 0,05, showed that the variable of sex, age group of the head household among 40-59 years old and the knowledge of environment did not have effect on household garbage management behavioral. Level education of the patriarch and capital income affected positively on domestic garbage management behavioral. Variable of age group of the patriarch above 60 years old did negatively affected to the domestic garbage management behavioral. Although knowledge about the environment did not affect eco-friendly behavior, but the knowledge about the environment has to be continued to be disseminated to the public. Right knowledge about the behavior of environmental awareness is a major component of internal factors that can drive change one's attitude to be more concerned about the environment

Limbah cair rumah sakit merupakan salah satu sumber pencemar bagi lingkungan yang dapat memberi dampak negatif berupa gangguan terhadap kesehatan, kehidupan biotik serta gangguan terhadap keindahan sehingga harus diolah terlebih dahulu sebelum dibuang ke lingkungan. Rumah sakit RK Charitas mempunyai Instalasi Pengolahan Air limbah (IPAL) namun selama ini belum pernah dievaluasi. Baku Mutu Lingkungan (BML) Limbah Cair Rumah Sakit antara lain berupa BOD, COD, TSS, amoniak bebas, fosfat, dan total coli. Dari hasil analisis keluaran limbah cair RS RK Charitas Palembang tenyata limbah cair ini masih memiliki kadar amoniak (NH3) dan fosfat (PO4) yang masih tinggi yang tidak memenuhi baku mutu lingkungan (BML) dan syarat BML yang lain berada pada ambang batas. Kadar PO4 sebesar 2,134-2,213 mg/l yang melebihi BML sebesar 2 mg/l dan kadar NH3 sebesar 0,174-0,186 yang melebihi BML sebesar 0,1 mg/l. Pada penelitian ini dilakukan evalusi instalasi IPAL Rumah sakit RK Charitas Palembang dari alur proses, waktu proses pengolahan, bahan pengolah air limbah, dan biaya pengolahan limbah cair dan memberikan solusi penyelesaian berupa redesain IPAL dan membuat miniatur IPAL usulan yang akan disimulasikan. Diharapkan usulan redesain Instalasi Pengolahan Air Limbah (IPAL) di Rumah Sakit RK Charitas akan menghasilkan kualitas limbah cair yang memenuhi syarat baku mutu lingkungan rumah sakit.Hospital wastewater is one of the pollution sources to the environment that can cause negative impact on human health and disruption into biotic life. Hospital wastewater must be treated before it discharged into the environment. RK Charitas Hospital Wastewater Treatment Plant (WWTP) has not been evaluated. Environmental Quality Standards (EQS) of wastewater hospital consists of BOD, COD, TSS, ammonia, phosphate, and total coliform. The analysis results of RK Charitas Hospital Palembang’s wastewater showed that the wastewater still have high level of ammonia (NH3) and phosphate (PO4) that do not sufficient to the environmental quality standards and other terms are at the threshold. Phosphate (PO4) level is 2.134 to 2.213 mg/l which exceeded the environmental quality standards is 2 mg/l and ammonia (NH3) level is 0.174 to 0.186 that exceeded the environmental quality standards is 0.1 mg/l. This research was conducted to evaluate the process, processing time, material, and costs of WWTP at RK Charitas Hospital Palembang and provide a solution for redesign a miniature WWTP that will be simulated. It is expected that the proposed redesign Wastewater Treatment Plant (WWTP) in RK Charitas Hospital will produce eligible effluent of hospital waste water towards environment quality standards.
