Abstract

Many developing countries have ventured to disaster management programs in the desire to minimize if not, eradicate disaster vulnerabilities and improve the coping skills of the people. Many ICT solutions have been developed and unfortunately, many of these are just one-time big-time solutions. Usability, transparency, costs of the systems and sustainability had become some of the issues. It is in this light that a working model of partnership between the academe and the local government unit (LGU) as a community is shaped. The academe takes the initiative in this endeavor. The tie-up is intended to support the LGU to become more responsive in managing its resources and addressing the needs of its constituents.The paper imparts the experience of the academe’s ICT project incubation for a community and further leads to a meaningful cooperation with the LGU. The ICT project developed is a flood prediction and mapping system for the province of Bulacan in the Luzon island of the Philippines.

Abstract

Onsite wastewater treatment system named Johkasou has been widely applied in the Japanese rural areas, which the effluent is mainly discharged into stream channels. However, Johkasou effluent would potentially be a source of contamination that can deteriorate water and sediment quality of the receiving downstream network. In order to identify the effect of Johkasou effluent particularly in sediment, a study on the distribution of fecal indicators (F-RNA bacteriophages, total coliform (TC), and Escherichia coli [E. coli]) in several sediment spots of local open channels receiving Johkasou effluent was conducted. The results showed that the contents of F-RNA bacteriophages, TC and E. coli in the sediment of open channels were detected in high levels while those contents in the sediment of Johkasou drainage channel were up to two orders magnitude higher than in the open channel. A high number of fecal bacteria in the receiving open channels was majorly influenced by the number of domestic households. Moderate correlations of fecal bacteria indicator with solid sediment and volatile sediment indicate that the sediment particles can be carriers of microbes to the downstream water networks. Therefore, water flushing and hydraulic events are suggested to reduce sediment depth that contained fecal bacteria indicator in the open channel.

Abstract

Kabupaten Sleman memiliki 19 titik lokasi penambangan rakyat yang belum memiliki ijin dari pemerintah. Kegiatan penambangan menghasilkan dampak positif dan negatif bagi lingkungan. Oleh karena itu perlu dilakukan penelitian mengenai kelayakan ekonomi dan lingkungan sebagai dasar untuk memberikan ijin bagi kegiatan pertambangan rakyat tersebut. Penentuan kelayakan ekonomi dan lingkungan menggunakan metode pengharkatan. Kelayakan ekonomi kegiatan penambangan menggunakan 3 parameter sebagai dasar evaluasi, baik untuk penambangan di bukit maupun di sungai. Parameter kegiatan penambangan di bukit adalah umur tambang, potensi pasar dan pemanfaatan bahan galian, dan benefit cost ratio (BCR). Sedangkan parameter kegiatan penambangan di sungai adalah perbandingan cadangan terhadap penggunaan bahan galian (PCPBG), potensi pasar dan pemanfaatan bahan galian, dan benefit cost ratio (BCR). Adapun parameter kelayakan lingkungan adalah jenis dampak yang dihasilkan dari kegiatan penambangan, yaitu Dampak Penting Hipotetik (DPH), Dampak Tidak Penting Hipotetik 1 (DTPH 1), dan Dampak Tidak Penting Hipotetik 2 (DTPH 2). Hasil penelitian menunjukkan bahwa dari aspek kelayakan ekonomi terdapat 10 titik lokasi tidak layak, 5 titik lokasi kurang layak, dan 4 titik lokasi layak. Sedangkan dari aspek kelayakan lingkungan terdapat 12 titik lokasi tidak layak, 4 titik lokasi kurang layak, dan 3 titik lokasi layak.

Abstract

Penelitian ini dilaksanakan untuk mempelajari karakteristik bio adsorbent dari serbuk kayu nangka dan meneliti kemungkinannya sebagai penjerap ion logam berat dari larutan. Percobaan adsorpsi dilakukan untuk menghitung kapasitas penjerapan bio adsorbent. Penelitian ini membuktikan bahwa pH larutan mempengaruhi perilaku penjerapan, dengan menaikkan nilai pH dari 2 hingga 4, maka kapasitas penjerapan juga meningkat. pH optimum larutan untuk penjerapan ion Pb(II) ke dalam bio adsorbent adalah pH 4. Model kinetika pseudo order dua cocok untuk menggambarkan proses penjerapan ion Pb(II) ke dalam bio adsorbent. Dari perhitungan model kinetika, diperoleh nilai kapasitas penjerapan pada kesetimbangan adalah 1,907 mg/g. Hasil analisa FTIR menunjukkan bahwa ikatan C–H, gugus karbonil –C=O dan gugus nitril –C≡N memberikan kontribusi pada pengikatan ion Pb(II) di permukaan bio adsorbent.

Abstract

AbstractSolid waste reduction and handling efforts require full community participation. Governments and stakeholders continue to improve solid waste reduction and handling. From 71 million tons of waste was produced, it was only capable of carrying out waste reduction of 6.5 million tons (10%) in 2015. The 3 R movement also has not shown significant result, it was only 7.5% of waste that is processed into compost and recycle, 10% still in the grave in the ground, 5% was burned, and 8.5% unmanaged. As much as 69% of the total waste was dumped into the waste landfill. For that we need an assessment the driving factors of sustainability of community-based solid waste management. This paper aims to analyze the driving factors of sustainability community-based solid waste management in the cities of Bogor and Balikpapan. The approach used in the form of qualitative research methods through the process of description, tendency, and interpretation. The results showed that there are 6 (six) driving factors that play a major role in the sustainability of community-based solid waste management in the cities of Bogor and Balikpapan. The driving factors include the role of community leaders, economic benefits, social benefits, environmental benefits, the management network, and the stimulation and facilitation of local government. Keywords: driving, sustainability, domestic waste, and community participation

Abstract

Gas stations are a common source of groundwater contamination by petroleum hydrocarbons. These pollutants are a health concern when people come in contact with the contaminated water when pumping from polluted wells, for example.  However, in Indonesia this problem remains largely ignored, despite some prominent leakage incidents at gas stations. The purpose of this study is to investigate the groundwater contamination by petroleum hydrocarbon from gas station in the greater Yogyakarta area in Indonesia. Screening criteria such as construction standards, reported leakage incidents, and geological and hydrogeological condition were used to identify gas stations with high risk of water contamination by petroleum hydrocarbon.  Gas station with close proximity with dug wells in which its water had been used for human daily consumption was selected for further analysis. Groundwater samples were then collected from dug wells located in the vicinity to this selected gas station and then analyzed for benzene, toluene, ethylbenzene, xylene (BTEX) by gas chromatography/mass spectrometry. Of the six sampling points, BTEX were detected with concentrations ranging from 0,008 to 25,631 ppb.  Concentration of benzene at sampling point 3 exceed the standards of Indonesian drinking water quality and WHO. These findings indicate that BTEX groundwater pollution may be a health hazard of currently unknown proportion in the greater Yogyakarta area. It is recommended to assess health risk associated with human daily consumption of BTEX polluted groundwater and also to test groundwater at all gas stations in this area and remediate those affected by BTEX.

Abstract

The liquid waste of the UNIPA Surabaya Environmental Engineering laboratory has not fulfilled the requirements of the Minister of Environment Regulation Number 5 of 2014, so it needs to be processed so as not to pollute the Environment. This study aims to examine the effect of the coagulant dose of Poly Alum Chloride (PAC) on decreasing Pb, Cr, and TDS, assessing the quality of wastewater after neutralization, coagulation and adsorption especially for Pb, Cr, TDS, and pH parameters. The variables of this study were PAC doses of 150 mg / L, 225 mg / L and 300 mg / L. The research was carried out on a laboratory scale with a continuous system with downflow. The adsorption media used are fibers, coconut fiber, bagasse activated carbon and multilevel zeolites in the reactor from the PVC pipe. Adsorption process is carried out for 2 hours and sampling every 15 minutes. The results of this study showed that the PAC 300 mg / L produced the highest reduction efficiency, namely TDS 13.7% Cr 97%, Pb 93.5%, and the quality of waste after neutralization, coagulated and adsorbed in the 15th minute having TDS 1.810 levels ppm, Cr total 0.36 ppm, Pb 0.66 ppm so that wastewater has met the quality standards in accordance with Regulation of the Minister of Environment No. 5 of 2014 while the pH of 5.42 does not meet the quality standard.

Abstract

Pengolahan limbah makanan diperlukan untuk mengurangi timbulan sampah yang akan masuk pada Tempat Pemrosesan Akhir (TPA) dimana rata-rata tiap orang di Indonesia membuang 300 kg tiap tahun. Pada penelitian pengolahan limb ah makanan dengan alat Food Waste Recycler (FWR) untuk menurunkan massa limbah dengan menggunakan metode conductive drying. Faktor-faktor yang mempengaruhi hasil dari pengolahan limbah makanan dengan menggunakan alat FWR, yaitu massa limbah, suhu, dan waktu pengolahan. Pada penelitian pengolahan limbah makanan 500 gram pada suhu 70oC selama 5 jam (S1) dan 10 jam (S2) dengan adanya pencacahan terlebih dahulu untuk mempercepat proses pengeringan. Berdasarkan penelitian menunjukkan adanya penurunan massa sampah pada sampel S1 39% dengan massa akhir 305 gram dan S2 73,2% dengan massa akhir 134 gram. Penurunan massa limbah karena adanya penguapan kadar air sampah akibat adanya panas yang dihasilkan dari sumber panas (heater). Selain itu pada sampel S1 tidak adanya perubahan warna dan memiliki bau busuk sedangkan pada S2 warna kecoklatan dan bau tidak seperti awal. Hasil Food Waste Recycler dengan metode conductive drying memiliki karakteristik kimia pada limbah sampel S1 pH 6,5, 0,81% nitrogen, 1,19% phosfor, 1,30% kalium, 11,6% karbon organik dan rasio C/N 13,8 sedangkan pada S2 pH 7, 0,54% nitrogen, 1,08% phosfor, 1,31% kalium, 8,36% karbon organik dan rasio C/N 15,5. Waktu proses yang lama menjadi faktor tingginya kadar kering limbah, adanya perubahan warna, bau, dan rendahnya kadar hara yang terkandung pada limbah.
