People have used rice husk as an isolator material to prevent melting block of ice by pour it to the block of ice. Rice husk as particle board have been developed as an alternative of isolator material especially for cold storage. Thermal conductivity was affected by many aspects; one of them is filler solid compression ratio. The value of thermal conductivity in the rice husk particle boards has been researched to thermal conductivity with modified of ASTM C177 method and with different solid comparison are: 6-1, 5-1, 4-1, 3-1 i.e from original thick to final thick. From the different of the value of thermal conductivity which was from every density, it was found that the highest value of the thermal conductivity was obtained on rice husk particle board with the density of 3-1 with the value of thermal conductivity 0,133 w/m°C on heat source 70 watt and 0,103 w/m°C on heat source 80 watt and the lowest value of the thermal conductivity was density with 6-1 with the value of thermal conductivity 0,096 w/m°C on heat source 70 watt and 0,082 w/m°C on heat source 80 watt.

Effect of plate joint on automobile body which susceptible to corrosion has been investigated also corrosion rate on automobile plate when the coating has impacted. Rain and sea water was used as corossion medium as normally affected on automobile plate. Low carbon steel has been choosed as standart plate. The forming of plate as a joint which folding and welding used a standart manufacture of automobile industry. The re-sults have shown the losses weight of plate faster on the sea water environment. After immersed in the sea water for 627 hours the corrosion rate of folding plate joint has 0.000806 mpy, although it was at a standstill outstanding level. Coating paint can decrea-sed 20% corrosion rate, but still need attention to care if the automobile body was impac-ted.

Rice husk particle board was expected to replace the established one, because it has advantages such as more heat and fire resistance that can be used in household appliances, building material, heat absorber, and cold storage. As an alternative building material, rice husk particle board should pass the testing processes that suitable to industrial standard include physical and mechanical properties. Particle board was made of resin and rice husk at 1:2 and 1:3 composition mixture and compacted ratio at 2:1, 3:1, 4:1 and 5:1 respectively used moulding that have a measurement 20 x 10 cm2. The testing included internal bonding, modulus of elasticity (MOE), modulus of rupture (MOR) and density of particle board. The results have shown that composition mixture 1:2 has more strength than 1:3. The highest compacted ratio needed more compacted pressure, i.e. on compacted ratio 5:1 has needed pressure 10.795 kg/cm2. Internal bonding of composition mixture of 1:2 has higher than 1:3. The highest value of MOE and MOR have received in 1:2 composition mixture with 5:1 compacted pressure are 5,088.75 kg/cm2 and 63.75 kg/cm2 respectively. The MOE on composition mixture of 1:2 has higher than 1:3. A particle board density ranges from 0.355 g/cm3 on 1:2 composition mixtures with 2:1 compacted pressure to 8.73 g/cm3 with 5:1 compacted pressure. The best of rice husk particle board used 1:2 composition mixture and compacted pressure of 5:1 which result in highest of MOE and MOR values.

Rotated of small motorboat propellers produced relative motion among propeller and fluid media (water) i.e. mechanical effect as thrust, cavitation and friction. The me-chanical effect with chemical and electrochemical reaction resulted corrosion on mo-torboat propellers. Tanjung Tiga was choosen with geographic reason, that can be a mo-del for the other place along north beach of Jawa Barat, which fisherman went to sea via muddy estuary. Erosion, pitting, cavitation and galvanic corrosions happened on small motorboat propeller. Increasing 10 % of rotation of propeller made corrosion rate higher more than 80%, because the estuary muddy and made shallow, the propeller have hard impacted when on river than on the sea.

The Covid19 pandemic that has hit the entire world since March 2020 provides various aspects of people's lives: economic, social, behavior, and life habits. One aspect that often occurs is the flood of information about a pandemic, especially in the early days of the virus outbreak. This community service aims to provide understanding in responding to the flood of information during the pandemic to the public, especially the women at the Persatuan Wanita Darussalam (PWD) in Darussalam 3 Residential, Ngemplak, Sleman. The method used in community service is by observing the subject, providing online counseling using the zoom meeting application by utilizing the RT / RW Net in the housing and followed by follow-up monitoring in the form of post-extension monitoring. The result of this service activity is that the community, especially, gets learning and understanding how to deal with the flood of information during the pandemic, especially in filtering real and false information (hoax).

Information and Communication Technology (ICT) has been used in every aspect of life. Children are familiar with ICT, both for learning and playing activities. The widespread use of ICT among children must be accompanied by parents' assistance, and supervision to obtain optimal benefits and minimize the disadvantages of using ICT. The community service program is carried out for mothers who are members of Kelompok Pemberdayaan Kesejahteraan Keluarga (PKK) in Sendari Tirtoadi, Sleman Yogyakarta by using the method of socialization and outreach to parents (especially mothers) about how to assist children in using electronic ICT devices, both for activities study and other activities and followed by the procurement of a survey of 25 participants. The results of a survey conducted on 25 participants obtained information that 100% of children have at least one ICT-based communication tool, 100% of children have used ICT equipment, 83% of parents do not follow their children's social media accounts or check their children's gadgets and 75% of people parents do not provide assistance to children's activities in using ICT equipment. These results indicate the need for socialization of how to be wise parents in the digital era, especially in assisting children in using ICT. The role of parents in mentoring is essential so that children can use IT well.
