I Gusti Ngurah Rai Bali International Airport is the second highest airport in activity level in Indonesia. Flight activity in this airport increases every year, with an increase of 20% from 2011 until the end of 2012. The research aimed to identify how much the LTO (Landing-Take-Off) emission activity in I Gusti Ngurah Rai Bali International Airport. The purpose of this research was to identify how much the emission is and the effect of LTO activities towards the ambient air condition of CO and NOx around the airport. Three measurement points and three days recent flight were applied to understand the emission spreading characteristic in every LTO phases. The three phases of LTO which are consisted of take-off phase, taxi in phase and landing phase, were the main focus of this research. The three recent flights were on Monday 5 of May, on Wednesday 7 of May and on Saturday 10 of May in 2014. Regression bifilar linear statistical analysis method was employed to identify the effect and how big the CO and NOx emission contribution towards the ambient air quality. The results of this research showed that the emission of aircraft activity in LTO phases was effected by the ambient air concentration of CO and NOx. It was proved with the result from F test simultaneous with significant level average 0,033 < 0,005 and with r value that exists between 0,77 – 0,97 with mean contribution was 79,1%. Take-off phase was the phase that produced the biggest NOx gas emission compared to the other phases. When the aircraft did the take-off phase, the thrust was used reached 100%, the purpose was to produce the big energy. The combustion that happened in take-off phase in aircraft machine classified in perfect combustion, also this thing effected the phase to produce the smallest CO gas emission compared with the other phases. Taxi in phase was a phase that produced the biggest CO emission between the two other phases, it was happened because the thrust needed just 7% only so the combustion in aircraft machine classified in imperfect combustion and it was effected the CO emission was increasingly while the landing phase was the phase that produced the smallest CO and NOx gas emission compared to the other phases. Measurement results of the CO and NOx concentration in every point in three days recent flight was still under the quality standard that has been settled appropriate in Government Act number 41 year 1999..
This community service activity aims to provide training on the use of KIT for prospective co.Ass students to improve guiding skills in basic physics practicum activities. The methods used are (1) the provision of materials, (2) the implementation of devotional activities, (3) monitoring and evaluation of activities. The service was conducted in the laboratory of IPA STKIP Weetebula for 6 (six) days in April 2021 involving 3 lecturers assisted by 9 students and 20 participants. The participants were very enthusiastic to participate in this activity because most are not yet proficient in using practicum tools. this activity can add insight and skills of students in using KIT IPA in IPA Laboratory STKIP Weetebula
Tujuan penelitian ini untuk menghitung besar nilai percepatan gravitasi bumi pada beberapa tempat dan mengetahui perbedaan nilai gravitasi bumi di Kabupaten Sumba Barat Daya. Jenis penelitian yang digunakan adalah eksperimen murni (true experimental) yaitu metode eksperimen yang paling mengikuti prosedur dan memenuhi syarat-syarat eksperimen. Pengambilan data dilakukan di setiap titik sampel yang tersebar di sepuluh kecamatan di wilayah kabupaten Sumba Barat Daya yang telah di tentukan berdasarkan teknik sampling yakni cluster sampling. Hasil yang di peroleh adalah rata-rata nilai gravitasi bumi di Kabupaten Sumba Barat Daya sebesar 9,98 m/s2.
The purpose of this activity is social services to provide Covid-19 vaccination services for people in Pogotena village – Loura Subdistrict, Southwest Sumba Regency – NTT. This activity was carried out in collaboration with STKIP Weetebula with the National Covid-19 vaccination assistance committee and also Salim Group (Indofood, Indomaret, ACA Insurance) and the Health Ministry of the Republic of Indonesia. The implementation of this activity by a team of lecturers from STKIP Weetebula consisting of three lecturers from the physics education study program, 1 lecturer from PGSD, and 1 lecturer from the Indonesian education study program involving 6 students. The result of this activity, namely: as many as 156 people in pogotena village can be served for vaccination using astrazaneca vaccine type. Some of the obstacles faced in the field are that many people have to go home because they do not qualify for vaccines, such as high blood pressure, the type of vaccine used only Astrazaneca so that it cannot reach people under the age of 18 years, and also services for the community who will do the second vaccine because the type of vaccine used is different from the type of vaccine available. The conclusion of this social service activity is that the community is very happy with the services of lecturers and students and very hopeful that this activity can be done again for residents who have not qualified for vaccines. With this social service activity, the Covid-19 vaccination process can be accelerated so as to realize healthy communities and villages
Online Learning Media Utilization Training Activities during the Covid-19 Pandemic for Elementary School Teachers in Loura District aim to improve teachers' knowledge and skills in using online learning media during the Covid-19 pandemic. The method used in this activity adopts a problem-solving learning model where each participant is given a problem related to the training material, then the trainee is asked to solve the problem and continue with the discussion activity classically. This activity began with a discussion activity with representatives of elementary school teachers in Loura subdistrict about learning problems carried out during the Covid-19 pandemic. Furthermore, an introduction to online learning media that can be used in the learning process and then the participants are trained about the techniques for using online learning media. This training activity provides understanding to trainees about the use of online learning media in the teaching and learning process, especially in the learning process during the Covid-19 pandemic. Participants of the training activities gave a positive response to the implementation of this training activity because they obtained knowledge related to the use and utilization of online learning media to help them in the learning process during the Covid-19 pandemic in their respective schools.
