“Eco Stand Lamp”, adalah nama yang diberikan untuk produk inovasi yang kami hasilkan menggunakan konsep 3R
iaitu “Reduce, Reuse dan Recycle”. Objektif penghasilan produk inovasi iniadalah untuk mengurangkan sisa produk
elektronik di Malaysia. Seiring dengan peningkatan kualiti hidup rakyat Malaysia, semestinya penggunaan produk
elektrik juga semakin meningkat. Sebahagian besar produk elektrik yang sudah rosak akan dibuang ke tapak
pelupusan sampah di mana kebanyakkannya terletak berdekatan dengan sungai. Hal ini menyebabkan impak negatif
kerana bahan kimia dan logam berat daripada sisa elektronik akan masuk ke dalam sistem tanah dan air bawah
tanah. Perkara ini amatlah berbahaya untuk alam sekitar kita. Justeru itu, timbul idea untuk menghasilkan “Eco Stand
Lamp” menggunakan kipas angin yang sudah rosak di mana, hanya bahagian kaki dan sebahagian badannya sahaja
digunakan untuk menghasilkan produk inovasi ini. Selain itu, antara bahan lain yang digunakan adalah kerangka besi
daripada lampu “downlight”, penutup botol mineral dan suis di mana ketiga-tiganya adalah bahan yang dikitar semula
untuk projek inovasi ini. Untuk projek Inovasi ini, hanya mentol led sahaja yang diguna semula (“reuse”). Oleh itu,
produk ini amatlah menjimatkan kos dan mudah untuk dihasilkan. Tambahan pula, ianya mempunyai nilai estetika,
mesra pengguna, adanya kecenderungan inovasi, mesra alam, ergonomik dan bernilai komersial yang mana boleh
menarik perhatian pengguna.
Kata kunci : inovasi, kitar semula, nilai estetika, nilai komersial, 3R

The need for renewable environmentally friendly energy resources is growing every day. Biodiesel is one of the most
promising alternatives to the conventional non-renewable energy resources. Heterogeneous catalysts proved a high
efficiency in the trans esterification of oils toproduce biodiesel. In this research, activated carbon derived from
agricultural waste namely: sugarcane bagasse, coconut husk and banana peel was tested as a heterogeneous
catalyst inthe trans esterification of waste cooking oil with methanol to produce biodiesel. Activated carbon was
characterized using scanning electron microscope and Fourier transformed infrared. The effect of different operating
parameters, namely operation time (30, 60, 120 and 180 min), alcohol-to-oil molar ratio (4:1, 6:1, 8:1 and 10:1) and
catalyst loading [0.5, 1, 2, 3 and 5% (w/w)] was investigated. Results showed that increasing the operational time, the
alcohol-to-oil molarratio and the catalyst loading increases the conversion to biodiesel but only to some extent;
increasing the stirring rate was found to be beneficial to the process. The optimum conditions were found to be
2 hours of heating, 6:1 alcohol-to-oil ratio and 1 wt% catalyst loading. Under optimum conditions, the conversion to
biodiesel reached 93.95 % for the waste cooking oil. The properties of the obtained biodiesel (density, viscosity, flash
point, pour point and cloud point) were measured giving promising results. The heat of combustion of the biodiesel,
which is compared to the heat of combustion of diesel fuel from crude oil were studied shows approximately 8%
smaller. Biofuel is recomended as a clean, biodegradable and biocompatible green product, which is in harmony with
the political and environmental awareness and in line with future strategies on renewable fossil fuels.
