In the paper the use of process models and computer simulation as the tools which facilitates students to learn the conditions of the industrial processes control has been presented. Such approach enables to familiarise with operation and programming of controllers of industrial process. Moreover, it also enables safe testing of control algorithms provided by logic controllers through their implementation at the real industrial facility.

Electrical Installation

Understanding of electrical installation and the use of electrical equipment that is proper and safe, has a big contribution to the safety and security around us. The introduction of safe electrical installations according to the Indonesian National Standard, namely the General Requirements for Electrical Installations (SNI: PUIL 2011) needs to be disseminated to the public from an early age. The problems were: (1) Socialization of electrical installations is less socialized to the wider community, (2) Socialization of SNI PUIL 2011 is less socialized by related parties, (3) There is no special curriculum that provides practical skills to junior high school students regarding safe electrical installations. External targets are students: (1) Can recognize the components of simple electrical installations in their homes, (2) Understand the functions and workings of installation components, (3) Understand the procedures for installing electrical installations, (4) Be able to plan installation installations electricity. The methods used were (1) lectures on understanding the importance of safe electrical installations, the functions and workings of installation components, (2) demonstrations using electrical installation module boards, (3) Questions and answers and discussions. The results achieved included students: (1) Understanding of simple electrical installations in their homes, (2) Understanding of electrical installation procedures and planning, (3) Being able to plan installations

Induced spinodal decomposition under electron irradiation in a Ni-Au alloy has been investigated with respect to its basic mechanism and confirmed to be caused by the relaxation of coherent strain associated with modulated structure. Modulation of white-dots on structure images of modulated structure due to high-resolution electron microscopy is reduced with irradiation. In this paper the atom arrangement of the modulated structure is confirmed with computer simulation on the structure images, and the relaxation of the coherent strain is concluded to be due to the reduction of phase-modulation.Structure images of three-dimensional modulated structure along <100> were taken with the JEM-4000EX high-resolution electron microscope at the HVEM Laboratory, Kyushu University. The transmitted beam and four 200 reflections with their satellites from the modulated structure in an fee Ni-30.0at%Au alloy under illumination of 400keV electrons were used for the structure images under a condition of the spherical aberration constant of the objective lens, Cs = 1mm, the divergence of the beam, α = 3 × 10-4 rad, underfocus, Δf ≃ -50nm and specimen thickness, t ≃ 15nm. The CIHRTEM code was used for the simulation of the structure image.

Insect Interactions

Food security and the sustainability of native ecosystems depends on plant-insect interactions in countless ways. Recently reported rapid and immense declines in insect numbers due to climate change, the use of pesticides and herbicides, the introduction of agricultural monocultures, and the destruction of insect native habitat, are all potential contributors to this grave situation. Some researchers are working towards a future where natural insect pollinators might be replaced with free-flying robotic bees, an ecologically problematic proposal. We argue instead that creating environments that are friendly to bees and exploring the use of other species for pollination and bio-control, particularly in non-European countries, are more ecologically sound approaches. The computer simulation of insect-plant interactions is a far more measured application of technology that may assist in managing, or averting, ‘Insect Armageddon' from both practical and ethical viewpoints.
