Jawa Barat memiliki potensi energi geothermal dalam jumlah yang besar. Akan tetapi pemanfaatannya terbatas untuk sumber geothermal dengan entalpi tinggi yaitu untuk penghasil tenaga listrik. Sedangkan pemanfaatan potensi energi geothermal dengan entalpi rendah yang dikenal dengan sebutan direct use masih belum dilakukan. Jika energi terbuang ini diberdayakan akan meningkatkan pembangun perekonomian dan kesejahteraan masyarakt di wilayah Jawa Barat. Dalam penelitian ini dilakukan pendataan sumber energi geothermal berentalpi rendah yang berada di Jawa Barat, selanjutnya pendataan potensi pertanian, perkebunan dan industry yang bisa dikorelasikan dengan energi geothermal berentalpi rendah. Selanjutnya dibuat peta potensi geothermal dan pemanfaatannya di propinsi Jawa Barat. Selanjutnya hasil pemetaan tersebut digunakan untuk membuat model pendayaguanaan entalpi rendah di Jawa Barat yang mengintegrasikan peran akademisi, peneliti, masyarakat, pemerintah daerah, pemerintah pusat, dan pelaku usaha sebagai pemilik modal dalam sebuah networking yang sinergis. Pengaplikasian model pendayagunaan energi geothermal memjanjika banyak keuntungan yaitu: meningkatkan ketahanan melalui pemanfaatan energi terbarukan, keuntungan kelestarian lingkungan, dan keuntungan atas social, politik dan ekonomi masyarakat di Jawa Barat.
Sugarcane remains to be one of the largest cash crops in the world. Despite its economic benefits, a large amount of bagasse generated from extraction processing ends up as an environmental issue. The utilization of bagasse as fiberboard is introduced as an alternative waste management. However, nowadays, fiberboard is commonly produced by adding chemical adhesive, such as Urea-formaldehyde resin, which is harmful to living things. The current research was conducted to study and produce environmentally friendly fiberboard by relying only on lignocellulose due to hydrogen bond formation. The methods used consisted of cutting, soaking, refining, concentration determination, and forming with various drying temperatures of 110ºC, 130ºC, 150ºC, 170ºC, and 190ºC. Characterizations of flexural and tensile strength were carried out to investigate the feasibility of fiberboard based on the standard of JIS A 5905 (2003). The calculations show that the increase in drying temperature from 110ºC to 190ºC increased the flexural and tensile fracture stress by 24.12-36.87 MPa and 12.89-19.77 MPa respectively with both maximum values obtained by fiberboard 190ºC. By considering the density and moisture content of fiberboards which ranged from 1.0210-1.0164 g/cm 3 and 6.19-4.19% respectively, the results indicate that only fiberboard 110ºC, 130ºC, and 150ºC meet the standard of JIS A 5905 (2003) for high-density fiberboard (HDF) with type of S20 and S25. HDF has applications for exterior siding, interior wall, paneling, and household furniture.
