Agricultural organic waste chopping machine are tools that can be used to chop leaves, twigs and could be used to help farmers in processing of the agricultural disposal products such as stalks and corn stalks, cassava stems, rice stalks in order to accelerate farmers in processing of those disposal in order that the plantation land can be prepared immediately for subsequent cultivation, as well as the chopped products can be reused for various purposes such as animal feeds and composts fertilizer. The research of this engineering method is carried out with the following stages: (1) study of the characteristics of several organic wastes to be enumerated, (2) analysis of the Chopping machine elements, consists of Chopping Blades, the house of the chopper blades, hopper, frame and transmission system. (3) A Prototype chop up mechanism manufacturing. And (4) Functional testing machine. The Copping Machine design resume as follows: Production capacity of enumeration 220 kg / hour. The cutting mechanism uses 2 static blades and 6 rotary blades. Transmission system using Belt-Pulley mechanism. The 24 Hp Diesel engine is used.

Dynamic signals acquired from rotary machines can be characterized by the order tracking (OT) techniques. The extracted order components correspond to the operation of specific machine elements and reflect their current healthy or faulty states. The study extends the angular-velocity Vold–Kalman OT scheme to simultaneously extract multiple order components. Theoretical derivation is illustrated with simulation of processing three synthetic signals to show its merit. Additionally, as an example to validate its effectiveness, the improved OT scheme is used to process pass-by noise emitted from an electric scooter with a planetary-gear-set transmission system. The gear-meshing orders are effectively decoupled from structure-borne resonances.

A pedal-operated cleaner-cum-grader having common bicycle chain-sprocket mechanism to get the speeds of 240 and 720 rpm of eccentric shaft and blower shaft, respectively for the desired cleaning/grading of grains was developed earlier by CIAE, Bhopal. Also, in order to utilize the human energy in more efficient way through pedalling mode, CIAE has recently developed a dynapod. The dynapod is a pedal operated rotary device, which can be used as an interface between human worker and any rotary-type machine. The developed dynapod was used to operate the cleaner-cum-grader to assess the drudgery reduction in its operation in comparison to original pedalling mechanism. The dynapod was interfaced with the cleaner-cum-grader by carrying out minor modifications in the original unit. Eight male agricultural workers with mean stature and weight as 168.4 cm and 54.4 kg, respectively participated in the study. The cleaner-cum-grader was used for cleaning and grading of soybean grains. Heart rate of the workers was measured during operation of cleaner-cum-grader using the dynapod as well as the original pedalling mechanism. Mean working heart rate during operation of machine with original pedalling mechanism was 114 beats min-1 as against 108 beats min-1 in case of pedalling with dynapod. The work pulse (ÄHR) with the original pedalling mechanism was 35 beats min-1 as against 29 beats min-1 during pedalling with dynapod. The output capacity of the machine increased from 303 kg h-1 in case of original pedalling mechanism to 345 kg h-1 with dynapod. Considering the cardiac cost as well as output of the machine, the drudgery reduction by using dynapod with cleaner-cum-grader was about 25.4% as compared to the original pedalling mechanism.

Mechanism of transformation plasticity (TP) is discussed from continuum mechanics viewpoint, and derivation of TP law from the unified thermo-mechanical and transformation plasticity constitutive equation. Result of identified TP coefficient for a chromium steel (JIS SCr420) by use of multi-functional testing machine is introduced as one of the material data together with other data to the simulation of a quenching process by use of newly developed code COSMAP. The simulated distribution of temperature, phases and stress/distortion are compared with the experimentally measured values to verify the accuracy.

<p><em><strong>Increasing of Earthworm Cultivation Business in Teras District Boyolali Regency.</strong> </em>Earthworms are soft-bodied, invertebrates, and have many functions as decomposer organisms, fertilizer producers from organic waste, and animal protein sources. Earthworms have high economic value. This community service aims to increase the capacity of earthworm cultivation through improved feed, use of vermicompost, and improvement of business bookkeeping on partner SMEs. The community service method is socialization, earthworm cultivation training, the introduction of media (feed), bookkeeping management training, and mentoring. Community service activities are earthworm cultivation training, introducing palm dregs and tofu dregs as media (feed), vermicompost as organic fertilizer, simple bookkeeping training, and mentoring. This community service activity can increase earthworms' production capacity by 50 - 70% per two months. SMEs have other alternative media (feed), namely palm dregs and tofu dregs, for worm cultivation. SMEs are already using vermicompost as organic fertilizer. SMEs have simple bookkeeping because they have recorded the financial income and expenditure of earthworm cultivation. Overall, this service activity has provided additional knowledge for SMEs to run a business so that the business is expected to progress and develop.</p>

<p><strong><em>Abstract</em></strong></p><p><strong><em></em></strong><em>Program IbM aims to 1) Establishing independent farmers in meeting the needs of fertilizer in rice farming, 2) create a technology organic waste treatment based on local resources, 3) Improving the knowledge and ability of farmer groups in production management manufacture bio composer, 4) Increasing awareness group peasants in farming that takes into account the principles of sustainable agriculture, 5) Establish new entrepreneurs that can increase farmers’ income. Target in the program IbM among others: 1) each farmer group has insight and knowledge of manufacturing technology bio composer, 2) each farmer group capable of processing organic waste (livestock manure, hump-banana stems, household organic waste), 3 ) each farmer group is able to manage the business bio composer well, managing of raw material supplies, scheduling, and organizing production capacity, 4) any farmer groups have treatment plants bio composer and its place, 5) any farmer groups can utilize thrasher organic materials, making it easier to cutting-banana stem weevil, vegetables or fruit. The method used in this activity are: 1) Training processing organic wastes into bio composer, 2) demo and facilitation manufacture bio composer together with farmer groups, 3) training and development of production management, 4) Training in the management of the finance, 5) leadership training (leadership) for the management, 6) Develop business into new profitable venture and 7) Making the MOL bio composer installation together with all members of the farmer group partners.

This paper reports a new microforce generating machine under development at NMIJ, AIST. We proposed a new microforce generating method by referring to the principle of the Kibble balance experiment and planned to apply it to a rotary type machine. Microforce in the micronewton and millinewton range can precisely be generated using this newly developed machine.
