“…Dengan menggunakan screw conveyor, dapat mengatasi masalah sampah yang tertumpuk ketika menggunakan kubus apung. Walaupun rancangan ini terdiri dari dua bagian pengangkat (screw conveyor dan belt conveyor), rancangan ini menggunakan transmisi yang memungkinkan kedua bagian tersebut untuk terhubung dan beroperasi dengan satu sumber daya [6]. Sumber daya yang di gunakan dalam rancangan ini bukan bahan bakar fosil sehingga dapat megatasi masalah pencemaran lingkungan yang di timbulkan dari menggunakan desain kapal atau excavator.…”

Garbage has certainly been a classic problem which tends to get worse, especially in Jabodetabek area. Various attempts were made to solve the waste problem in the cities. This raises the writer's desire to make a tool that can clean trash in the river automatically, far-reaching, and effectively, namely the lifting garbage conveyor. With this design, garbage can be cleaned continuously because of the automatic system. Even if the volume of garbage in the river increases, the tool can increase the speed of cleaning the garbage by itself. With the sensor system, the tool can continue to operate, without allowing trash to accumulate, using energy effectively, and not requiring a lot of human labor. This tool is designed to cover the entire river and it is capable of being assembled. Because the tool can run automatically, it only takes 1 to 2 workers whose to supervise and do not need to work physically. This tool is easy to operate. To start this tool, you don't need special skills such as the ability to drive when using an excavator.

“…The moisture content of the biomass used for energy production is a key parameter for the proper management of the power plant or in the densification process [2][3][4][5]. Generally, the wet wood biomass has a moisture content, on a wet basis, higher than 50% [6,7] and the natural drying process hardly lowers the moisture contents under 35% in 3-4 months of storage [8,9].…”

“…High moisture content of fuels increases the cost of transport, reduces the combustion efficiency [10], and decreases the potential energy input for steam generation. Consequentely, a reduction in the calorific value of the fuel gas produced in gasification is experienced, with a negative effect on the efficiency of power generation in combustion, gasification systems, and pyrolysis processes [5,11,12]. Concerning human health, higher biomass moisture content causes an increase of CO and VOC emission [7] as well as the formation of carcinogenic compounds from wood combustion [13,14].…”

“…The most common industrial systems for drying biomass are conveyor dryers, rotary dryers of single or multiple passes, fixed and mobile bed dryers, perforated floor bin dryers, direct and indirect fired rotary dryers, cascade dryers, superheated steam dryers, microwave dryers, fluidized bed dryers, screw conveyor dryers, and flash or pneumatic dryers [5,23,27]. However, it is known that rotary dryers have a low cost of maintenance and consume 15% and 30% less in terms of specific energy that the pneumatic and cascade types, respectively [6].…”

“…They have lower maintenance costs and greater capacity than any type of dryer. The drying process of the wet biomass in a rotary dryer can be challenging owing to the prolonged time for the uniform drying of the biomass [19], this can also increase the fire hazard inside the dryer [5,18].…”

Drying is a critical point for the exploitation of biomass for energy production. High moisture content negatively affects the efficiency of power generation in combustion and gasification systems. Different types of dryers are available however; it is known that rotary dryers have low cost of maintenance and consume 15% and 30% less in terms of specific energy. The study analyzed the drying process of woody residues using a new prototype of mobile rotary dryer cocurrent flow. Woodchip of poplar (Populus spp.), black locust (Robinia pseudoacacia L.), and grapevine (Vitis vinifera L.) pruning were dried in a rotary drier. The drying cycle lasted 8 h for poplar, 6 h for black locust, and 6 h for pruning of grapevine. The initial biomass had a moisture content of around 50% for the poplar and around 30% for grapevine and black locust. The study showed that some characteristics of the biomass (e.g., initial moisture content, particle size distribution, bulk density) influence the technical parameters (i.e., airflow temperature, rate, and speed) of the drying process and, hence, the energy demand. At the end of the drying process, 17% of water was removed for poplar wood chips and 31% for grapevine and black locust wood chips. To achieve this, result the three-biomass required 1.61 (poplar), 0.86 (grapevine), and 1.12 MJ kgdry solids−1 (black locust), with an efficiency of thermal drying (η) respectively of 37%, 12%, and 27%. In the future, the results obtained suggest an increase in the efficiency of the thermal insulation of the mobile dryer, and the application of the mobile dryer in a small farm, for the recovery of exhaust gases from thermal power plants.
