Abstract

Municipal waste from day to day has increased its production in line with the increase of urban population. However, running a waste management system has been unable to solve the problem of waste properly. Therefore, a new breakthrough is needed to deal with. With the enactment of Law No. 18 of 2008 on Waste Management, each source must be to reduce the amount of waste to be disposed of to the final processing of waste. The office is one of the sources of waste, also must reduce the amount of waste that must be disposed of to the final processing of waste (landfill). The purpose of this paper is to examine waste management in an integrated manner to maximize the waste management office. In the process of management, garbage collector used by officers in the study. The rest moved to the TPS waste. In this place officers also collect that is still valuable economic and processed organic waste into compost. Of these operations, the rest of office waste disposed to landfill about 48.7%keywords : office waste, integreted office waste management

Abstract

An increase on population and income of people will be followed by an increase on the energy utilization. As consequence, the CO2 emission from the energy utilization also increases that has impact on increasing environmental problem. The increase of CO2 emission can be reduced by the utilization environment friendly energy source and technology such as using low carbon energysource and increasing the effi ciency of energy technology. In 2008, most of CO2 emission from energy utilization in the world was contributed from OECDcountries. Most of the CO2 emission from the energy utilization was from electric generation sector. The CO2 emission from energy source is infl uenced by carbon content and combustion system that used in the utilization. Total CO2 emission in the world was almost 33.932 million ton that about 1,3% or 438 million ton was contributed from Indonesia. These emission is estimated to increase in thegrowth rate of 3,5% per year until 2030.Key words: CO2 emission, energy utilization.

Abstract

Kawasan lahan-lahan marginal memerlukan penanganan yang intensif agar kerusakan lahan dapat diturunkan. Revegetasi menggunakan metode hydroseeding telah banyak dilakukan dengan hasil yang sangat memuaskan. Aplikasi hydroseeding optimal dan ramah lingkungan memerlukan kajian dan penelitian terutama berkaitan dengan pemilihan zat aditif yang cocok sebagai pengganti zat aditif yang biasa digunakan dalam hydroseeding. Pengunaan guar gum sebagai pengganti perekat ramah lingkungan dalam hydroseeding karena memiliki sifat biodegradable. Penelitian ini bertujuan mengkaji pengaruh bahan aditif (Guar Gum) dan penanaman benih rumput Bermuda terhadap jumlah tanah yang tererosi serta mengkaji konsentrasi bahan aditif (Guar Gum) yang efektif terhadap penurunan laju erosi dengan metode hydroseeding. Metode yang digunakan deskriptif dengan media tanam lumpur (Sludge) bertekstur dominan pasir. Guar Gum dengan konsentrasi 0.5%, 1% dan 1.5% masing-masing dicampurkan dengan air sebanyak 5000 ml dan pupuk NPK 10 cc, kemudian disemprotkan pada box yang berukuran 38 cm x 28 cm x 13 cm yang telah ditaburi dengan pupuk kompos, sekam padi dan benih rumput bermuda. Pengamatan erosi dilakukan setiap kejadian hujan. Hasil penelitian menunjukkan semakin kental konsentrasi guar gum, maka semakin kecil jumlah tanah yang tererosi. Pertumbuhan benih rumput Bermuda pada konsentrasi 0.5% lebih banyak dibandingkan dengan konsentrasi 1% dan 1.5%. Namun, berdasarkan uji Regresi menyatakan bahwa konsentrasi 1% merupakan konsentrasi yang paling baik dalam laju erosi dan pertumbuhan benih rumput Bermuda.kata kunci: guar gum, hydro-seeding, laju erosi, rumput Bermuda

Abstract

Gedung perkantoran X di Jakarta dalam mengolah air limbah telah memiliki sarana pengolahan air limbah berupa IPAL dengan menggunakan teknologi lumpur aktif dan proses biofilter serta penambahan disinfektan untuk membunuh mikroorganisme. Seiring berjalannya waktu kondisi operasional IPAL kurang optimal dan sudah tidak berfungsi dengan baik sehingga air olahan IPAL tidak memenuhi baku mutu air limbah domestik sehingga perlu dilakukan evaluasi terhadap IPAL yang ada. Tujuan kegiatan ini adalah melakukan evaluasi kinerja dari IPAL Gedung Perkantoran X. Dari hasil survei dilapangan menunjukan bahwa beberapa unit operasi IPAL seperti airlive, scum skemer dan media tumbuh mikroorganisme pengurai polutan (sarang tawon) tidak berfungsi dengan baik. Hal ini disebabkan karena media tersebut tersumbat oleh lumpur sehingga sistem tidak beroperasi dengan baik. Berdasarkan hasil analisa dilaboratorium nilai BOD, COD dan jumlah total coliform masih diatas baku mutu air limbah domestik yaitu berturut-turut sebesar 35 mg/L, 103,5 mg/L dan 3 x 107 Jumlah/100 ml Kata Kunci : Limbah domestik, lumpur aktif, biofilter

Abstract

Indonesia?s disaster potential is very high and varied. Natural conditions, population and cultural diversity in Indonesia cause in increased risks due to natural disasters, man-made disasters and emergencies to be complex, on the other side Indonesia is rich in natural resources. Disaster relief should be directed from pre-disaster phase, during emergency response and post disaster. The initial phase of this effort is the need for understanding of all stakeholders (mainly institutions) about the development of the concept and paradigm change mitigation. By knowing the concept and development of this paradigm is expected that all stakeholders can do things from the smallest to the larger and synergies will occur from all stakeholders to minimize the impact of a disaster. From ancient times until now the concept of a paradigm in disaster management shift very rapidly starting from the conventional to the holistic paradigm. In general, the development paradigm is the conventional paradigm (relief emergency), mitigation paradigm, development paradigm and paradigm of risk reduction. Paradigm that is now growing and effective enough to minimize the risk mitigation is the analogy of mitigation for diseases caused by poor environmental sanitation. The analogy with disease problems mentioned above, there are disasters which can now be viewed in the same perspective, where the current disaster is something that is not predictable and it is destiny or part of the risks of everyday life. The concentration of people and higher population levels worldwide would increase the risk of disasters and multiply the consequences of natural hazards as dangers that arise. However, based on science ?of epidemiology disaster? actually most of these disasters can be prevented or at least many ways to reduce the impact of a disaster (mitigation actions). Like the war against disease, warfare should be fought against disaster by any person jointly and involve society as well as changes in social behavior as well as improvements in individual practices.Keywords : mitigation, disease, environmental sanitation, disaster
