Studies conducted on PVT air collectors.

Solar energy is renewable and environment friendly and has been widely used in electricity generation and thermal energy through photovoltaic thermal (PVT) system. This system is beneficial in terms of maximum energy generation and cost of usage. The growing concern on energy sources and their usage has increased the significance and demand for PVT collectors. A PVT air collector consists of a PV panel and a thermal collector system. In PVT air collector, electricity and thermal energy are generated simultaneously. This review focuses on efficiency and energy modelling for PVT air collector with extended heat transfer area. Findings of this review indicated that PVT air collector with extended heat transfer area produced PVT efficiency higher than conventional PVT air collector. The thermal efficiency of PVT air collector for with and without extended heat transfer area are 21-83% and 12-70%, respectively, which the improvement of thermal efficiency is 15.7-42.8%.

Disability students and MIE TITI media.

The condition of Gorontalo City has a high level of vulnerability to earthquake hazards, therefore understanding of earthquakes needs to be done early on, especially for children with disabilities. MIE TITI aims to increase earthquake mitigation knowledge and ability for students with disabilities at SDLB Gorontalo City, especially the visually impaired, deaf, and mentally disabled. The method to be used is a fun learning method with instruments used in the form of MINING (Music Fun Learning), MICARD (Mitigation Flascard), MINAME (Mitigation of Nature Game) and Oil and Gas (Mitigation Praise). A sample of 34 people with disabilities in Gorontalo City SDLB consisted of blind, deaf and retarded students. The results obtained are an increase in earthquake knowledge and earthquake mitigation ability in students with disabilities where in children with visual impairment by 50% and 35%, deaf by 45% and 55%, and mental retardation by 3% and 2%.

Limestone outcrop (Umar, 2019).

Geological hazards at Meluhu-Lasolo North Konawe are much more destructive when prevail can cause greater damage to lives and properties of humans when not properly and timely controlled and mitigated. This study aims to do an inventory of the types of disasters and determine all the locations that disaster-prone at Meluhu-Lasolo North Konawe Regency. The research method that will be used is an inductive method with approach combination between qualitative research and quantitative research, integrate all the literature review's results, field data, and all the results from laboratory computation research which have been reviewed, analyzed, and synthesized comprehensively. The result of this research is there is 2 (two) points of prone locations and the type of disaster is a landslide in the form of debris slide and rockfall, it is including as a high category of disaster-prone (score 4) with slope ranges from 29-850. The cause of that landslide is because that area has a steep slope, high rock weathering, cracked rock and easy to fall off, including fault line, slope that cut off by the road and vibration from all the high load vehicle that passing by, make the drainage channel defective and threatening human lives or the vehicle that passing by. There are a few things that have to do independently by the people who live there is to be more alert when rainy season come and fix all the road that have been cracked, and soil conservation.

Buku Geologi dan Manifestasi Thermal Libungo.

Geotermal atau panas bumi adalah salah satu sumber energi terbarukan yang potensinya melimpah di Indonesia. Pemerintah Indonesia melalui Badan Geologi terus mendata dan meneliti potensi geotermal di seluruh wilayah Indonesia. Penelitian terhadap potensi geotermal juga dilakukan oleh para peneliti di perguruan tinggi. Buku ini membahas kondisi geologi dan manifestasi termal di daerah Libungo, Kabupaten Bone Bolango. Pembahasan difokuskan pada manifestasi termal, stratigrafi, struktur geologi, geomorfologi dan hidrogeologi daerah Libungo.

Ilotidea radar research team.

Floods are natural disasters that often occur in Indonesia, one of them in Gorontalo Province. Flood handling must begin with an understanding of flooding and geological conditions that have the potential to cause flooding. This study aims to determine the causes of flooding that occurred in the Ilotidea area based on the analysis of SRTM radar image data. SRTM data is processed and produces a 3D watershed hydrology surface model. Hydrological modeling is then carried out to obtain a 3D hydrological model on the surface of the Ilotidea region and its surroundings. Analysis of 3D watershed hydrology models and 3D hydrological models on the surface of the Ilotidea region and beyond to determine the causes of flooding in the Ilotidea region. Based on SRTM data, Ilotidea region consists of mountains morphology and lake plains. Surface modeling of 3D watershed hydrology shows that the Ilotidea region is in the Bolango watershed. The hydrological 3D surface model of the Ilotidea region shows that the flooding was caused by the overflow of Limboto Lake and Bolango River. Based on the results of the study, it can be concluded that when high-intensity rain occurs it will cause Limboto Lake and Bolango River to overflow, then causing flooding in the Ilotidea area.
