Abstract

Abstrak: Aki digunakan sebagai sumber tenaga pada sepeda motor, mobil, truck, traktor, perahu dan berbaga jenis kendaraan bermotor lainnya. Berbeda dengan baterai primer atau baterai alkaline yang banyak digunakan dalam peralatan rumah tangga, aki merupakan baterai yang dapat diisi ulang setelah energi yang terdapat dalam aki telah digunakan. Penggunaan kembali material aki bekas kendaraan bermotor dengan cara mendaur ulang merupakan salah satu cara yang efektif untuk menghindari polusi lingkungan dan mengurangi volume timbulan aki bekas kendaraan bermotor di Tempat Pembuangan Akhir. Reduksi timbulan aki bekas kendaraan bermotor di Kota Bandung tidak terlepas dari peranan para pelaku daur ulang sektor informal. Aliran material aki bekas kendaraan bermotor pada pelaku daur ulang sektor informal di Kota Bandung secara garis besar adalah pemulung/tukang loak "“ lapak "“ bandar kecil "“ bandar besar dan akhirnya menuju pabrik daur ulang. Dari hasil survei yang dilakukan di Kota Bandung terdapat 159 pelaku daur ulang yang terdiri dari 48 orang pemulung, 59 orang tukang loak, 28 buah lapak, 8 buah bandar kecil dan 16 buah bandar besar. Jumlah aki bekas pada pemulung dan tukang loak, yaitu sebesar 19,5 ton/bulan pada pemulung dan 5,9 ton/bulan pada tukang loak, 1,2 ton/bulan pada lapak dan 1,6 ton/bulan pada bandar kecil. Sedangkan jumlah aki bekas kendaraan bermotor pada bandar besar adalah 24,7 ton/bulan. Di Kota Bandung pada tahun 2009, harga beli aki bekas kendaraan bermotor pada pelaku daur ulang berkisar antara Rp. 4.600/kg-Rp.5.900/kg, sedangkan harga jualnya berkisar antara Rp.5.600/kg-Rp.7.400/kg. Kata kunci: aki bekas kendaraan bermotor, daur ulang, sektor informal, aliran material Abstract: Lead acid batteries are relatively simple electrochemical devices able to store electrical energy, and deliver it to motors and other appliances when needed. Unlike common dry cell or alkaline batteries used in torches and other household appliances, lead acid batteries may be recharged after the stored energy has been used. As a result of these degradation processes batteries become unusable and are then known as used lead acid batteries (ULABs), and are waste. The utilization of ULABs by recycling is an effective method to avoid pollution of the environment and reduce the ULABs generation in the final disposal. The reduction of ULABs in Bandung City is not leave apart from the role of the recycle performers of informal sector. The material flow of ULABs in Bandung City by the informal sector of recycle performers are by pemulung/tukang loak "“ lapak "“ bandar kecil "“ bandar besar "“ and finally are going to recycling factory. Survey's result that is done at Bandung City exists 159 informal recycling performers that consist with 48 pemulung, 59 tukang loak, 28 lapak, 8 bandar kecil, and 16 bandar besar outgrow. The utilization of ULABs by recycling is an effective method to avoid pollution of the environment and reduce the lead generation in the final disposal site. The amount of vehicle's ULABs in the pemulung and tukang loak are 19.5 tons / month in pemulung and 5.9 ton / month on the tukang loak, 1.2 ton / month on the lapak and 1.6 tons / month in the bandar kecil. Whereas the vehicle's ULAB is 24.7 ton / month in bandar besar. In Bandung City in 2009, the buying price of ULABs is between Rp.4,600/kg- Rp.5,900/kg, whereas the selling price revolved between Rp.5,600/kg-Rp.7,400/kg.  Keywords: motor vehicle's ULABS, recycling, informal sector, material flow

Abstract

Mangroves are one of the coastal plants that have various benefits. One of the benefits of mangroves is preventing abrasion. However, in some cases the survival rate for the mangroves is low due to various influencing factors, one of which is water conditions. Therefore, intervention is needed to increase the survival rate of mangroves. One intervention that can be carried out is by implementing Domang (Donat Mangrove) planting method which aims to protect mangrove seedlings from extreme water conditions. This method was implemented in Klayas Village which is in the strait area. This research aims to determine the effectiveness of the implementation of Donat Mangrove in increasing the survival rate of mangroves in Klayas Village. So far, the survival rate for mangrove planting in Klayas Village is only around 12% due to the extreme water conditions. However, Donat Mangrove method effectively increases the survival rate of mangrove planting by up to 31%. This shows that the application of Donat Mangrove planting method is effective in increasing the survival rate of mangroves in Klayas Village.
