Identifikasi Kapasitas Tampang Minimum dan Stabilitas Mulut Muara Sungai Siak Propinsi Riau
Full text linkChanges in river mouth section capacity caused by instability of river mouth stability would influence flow conditions in upstream estuaries, as impacted by unsmooth drainage of river flow. Section river capacity and mouth river stability of Siak River would be evaluated by the output of tidal prism at the estuary. The tidal prism was predicted by Hecras software. Input data for hydrodynamic simulation consisted of river geometric data, river bed condition, and boundary condition (discharge and water level). The maximum daily rainfall data and Siak’s catchment parameter could predict flood discharge. Longshore sediment transport netto data could be calculated using wave depth data, wave velocity data and direction of wave around the mouth river. The results of the tidal prism calculation show that the existing cross-sectional area of the mouth of the Siak River estuary can only drain the volume of water due to discharge and tides in the 2-year return period (Amin = 3,115 m2 < A ada = 3,225 m2), while for discharge with other return periods, the capacity of the cross-section river is not sufficient. The excess discharge will flow upstream as a backwater. Siak River mouth stability is still relatively good and stable, with a stability number (S) of more than 388,0 (requirement: S > 150). The start of the backwater effect at KM+220 (60 km from the mouth of the river) caused a significant change in water level (0.94 m) due to the damming of the flow caused by the influence of tides and the bifurcation node of the river (delta)

Pengaruh Jenis Biomassa dalam Proses Karbonisasi terhadap Efisiensi Burner Tipe GT40
Full text linkThe use of biochar as an organic fertilizer has gained significant attention in the agricultural field. Biochar application can enhance soil fertility and promote agricultural sustainability. Converting agricultural waste into biochar can reduce dependency on chemical fertilizers. Incorporating biochar into the soil improves water retention and nutrient availability. This study aims to evaluate the effect of biomass types (bromelain and bamboo) during the carbonization process on burner efficiency in biochar production.The study utilized bromelain biomass, bamboo biomass, and a mixture of the two at a 50% bromelain and 50% bamboo ratio. The raw materials were carbonized using a rotary drum reactor. The reactor operated with heat supplied by a High-Speed Diesel (HSD)-fueled burner. The carbonizer reached a maximum temperature of 600°C. In addition to biochar, the carbonization process also produced syngas, which was subsequently used to substitute HSD as a fuel source.The results indicated that the type of biomass significantly influenced burner efficiency during the carbonization process. Biochar derived from bamboo tended to have a higher cellulose content, whereas biochar from bromelain exhibited greater thermal decomposition stability. This study provides new insights into the potential of utilizing bromelain and bamboo biochar as sustainable strategies for agricultural soil management.The research demonstrated that biomass type selection during carbonization had a substantial impact on burner efficiency, which ranged from 81.15% to 84.45%. The HSD consumption of the burner was recorded at 35.03 kJ/hour. The use of biochar as an organic fertilizer offers an environmentally friendly and sustainable solution. Converting agricultural waste into biochar can serve as a strategic agenda for agricultural waste management
