Kota Lhokseumawe yang pernah diklaim menjadi kota bebas sampah ini juga terkenal karena dua kali mendapatkan penghargaan Adipura oleh Presiden RI. Dalam hal mengelola sampah pada tahun 2009 dan 2010. Akan tetapi volume sampah yang ada di selokan dan di Waduk Lhokseumawe tentu permasalahan serius yang membutuhkan perhatian khusus. Kesadaran masyarakat akan kebersihan penulis rasa masih sangat kurang. Kedisiplinan dalam membuang sampah harusnya selalu di terapkan. Dengan terwujudnya mesin pengangkat sampah sistem chain conveyor otomatis ini dapat mengurangi penumpukan sampah diselokan maupun irigasi yang bisa menghambat air mengalir. Dalam pengoperasian mesin ini dimana sensor mendeteksi jarak sampah yang terdapat pada aliran air dengan jarak 1 cm diatas permukaan air, sensor memberikan sinyal kepada micro controller untuk mengaktifkan motor penggerak bucket yang mengangkat sampah yang terdeteksi oleh sensor ultrasonic untuk dimasukan ke dalam bak sampah yang terdepat pada mesin pengangkat sampah otomatis. Motor akan hidup dalam durasi 2 menit 30 detik (00:02:30), dan motor akan hidup kembali ketika sensor mendeteksi sampah berikutnya. Beban maksimal yang dapat diangkat oleh bucket 5 kilogram.Kata kunci: Mesin Pengangkat Sampah Sistem Chain Conveyor Otomatis.

The article deals with the calculation of the drive and chain transmission of the newly created mechanized drying plant for drying melon slices. The essence of the utility model: the machine contains a horizontal tunnel chamber, inside which is mounted a chain conveyor with driving and driven sprockets, load-carrying elements, the IR emitters with reflectors on top of the camera mounted electric air heater, fan, an annular heat exchanger equipped with inlet and outlet nozzles of the drying agent. On the branches of the conveyor chain, lodgments with folding clamps are mounted, on which load-bearing elements are fixed, which are used as wooden poles. The calculation of the drive and chain transmission of the drying plant conveyor was carried out according to the existing method according to the scheme shown in the figure. Thus, the main parameters of the drive and chain transmission parts of the mechanized chamber-chain drying plant for drying melon fruits were determined by calculation

A small-scale maize harvester was designed and fabricated for developing countries and is composed of a harvester header, a chain conveyor, a drive power unit and a five-wheel tricycle. Fabrication of components was made and assembling of the devices on the tricycle was done. The performance evaluation of the small-scale maize harvester was done at 15% kernels moisture content (wet basis). Three rotational speeds of the engine, 1347, 1521 and 1937 rpm were used, while the forward velocity of the harvester was kept at an average of 0.617 km.hr-1. The testing experiment revealed significant effect of physical properties of maize (p<0,05). The highest machine capacity was obtained at 0.05 ha.hr-1, while the highest driving efficiency was 97.30% and the highest picking and conveying efficiencies were 84.11% and 98.21%, respectively. However, it was observed that the machine noise level decreased with increase in engine speed. Also, the engine speed affected both picking and conveying efficiencies. The designed machine is found suitable for most smallholder farms.

Climate Change is a crucial challenge of today. The main reason is increased man-made emissions of climate gases, like CO2, into the atmosphere. In every part of our life, these emissions have to be reduced. Transport of goods, called intra- or extralogistics, is necessary for economic welfare. Intralogistics means the transport of goods in distribution centres or manufacturing spaces, e. g. between machines. For continuous transport processes chain conveyor systems (CCS) are state of the art. The research group “Plastic Components and Tribology” at professorship of Conveying Engineering and Materials Handling focus on impacts of their whole life cycle, from design over use until end-of-life, on the environment. Another focus is the development of Environmental Product Declaration (EPD) for chain conveyor systems. They are useful to promote environmentally-friendly products and to push eco-design activities. But also, activities of circular economy such as recycling of the plastic parts from conveyor chains are examined. The article gives an overview of the goals achieved and the challenges ahead. Some of the achieved results will be presented.

Chain Links

In continuous conveyor systems with circulating traction mechanisms, e.g. chains, the kinematic-dynamic movement behaviour of the traction mechanism is of great importance. Force and vibration analyses can be used to detect overloads and other irregularities in the conveying process. This helps to prevent damage that can lead to a complete failure of the conveyor system. Such analyses are particularly interesting for slide chain conveyors with plastic chains, as these react very sensitively to system overload due to limited thermal and mechanical characteristics as well as often a complex track layout. This article shows how accelerations and tractive forces can be continuously recorded, transmitted and analysed by sensors integrated into the chain links. In addition to the discussion of test results, potential applications of the measuring chain are shown.

Literature indicates availability of dynamic analysis of a drive shaft of a chain conveyor in a limited way. Relations for estimation of a conveyor chain pull to overcome, (i) Rolling resistance of the track, (ii) Tail sprocket and drive sprocket shaft bearing friction resistances, (iii) Drive and tail sprocket chain binding resistances and (iv) Impact loading on the chain have been only derived [1,2]. However, further extension to deduce the load torque demand on drive sprocket during one articulation of the chain is not seen derived in the literature. This paper details this, followed by digital computer simulation including illustration of application of this new procedure to a representative case study. Work on the same lines is not much seen in the literature. However, similar work by Harrison [4] is done for the belt conveyor.
