Research has been carried out to examine the use and mastery of ICT for science teachers in underdeveloped areas. This study aims to: obtain valid data regarding teachers' ICT knowledge and skills; knowing the extent to which the teacher implements ICT knowledge and skills in the classroom; identify the factors faced by teachers in implementing ICT in learning; to determine support and effective ICT development strategies to be applied to teachers. The research method is a survey, practical test, and statistical validation. It found that male teachers, young teachers, honorary teachers, and secondary school teachers tended to have higher ICT competence. It was found that the ICT applications that have been used by more than 50% of teachers are word processing, presentation processing, internet, and document navigation. The analysis results show that only about 2% of teachers stated that ICTs had little effect on their learning in the classroom and that training on how to do this had the most positive impact on teachers. It can be concluded that professional training on ICT needs to be effectively and sustainably provide; continuing to improve ICT infrastructure in schools will positively impact the use of ICT by teachers; teachers' overall attitude is very positive for self-development.

This Thematic Real Work Integrated with Community Service aims to increase the literacy of the people of Southeast Sulawesi regarding COVID-19 and how to mitigate it by using creative content media. This thematic program is one form of community service, so that its implementation follow the action research method with 5 (five) stages, i.e. (1) Diagnosis; (2) Planning; (3) Implementation; (4) Evaluation; and (5) Special learning. This thematic program was attended by 22 students under supervision of three field lecturers and lasted for 30 days online. During this program, more than 20 posters/e-cards and 30 videos have been produced. The content has been disseminated on various social media through the accounts of students and supervisors as well as other internet media. Based on the results of creative content in the form of posters, the public can improve their literacy on social and physical distancing as an effort to accelerate COVID-19 mitigation. Meanwhile, creative content in the form of videos can train the public on how to use and prepare their own hand sanitizer, masks, and PPE by utilizing materials found around them. Thus, it can be concluded that this thematic program has succeeded in providing guidance and debriefing to the people of Southeast Sulawesi as a mitigation effort against the COVID-19 outbreak.

The use of ecoenzymes is an effort to answer the problem of using inorganic fertilizers and environmental damage which is increasingly being used among farmers because their use has a negative impact. The target of implementing community service activities that are integrated with the Thematic KKN program are farmers in Lebo Jaya Village, Konda District, South Konawe Regency which have been designated as Organic Agriculture Areas. Most of the farmers in Lebo Jaya Village still use inorganic fertilizers and synthetic pesticides. The purpose of this activity is to provide farmers with an understanding of organic farming through training on making ecoenzymes. The output of this activity is that farmers are expected to gradually reduce or even no longer use inorganic fertilizers and start switching to the application of organic farming based on household waste.

Penelitian ini bertujuan untuk mengetahui bagaimana validitas, reliabilitas, tingkat kesukaran dan daya pembeda dari instrumen tes diagnostik tiga tingkat yang dikembangkan dan bagaimana profil miskonsepsi peserta didik SMA Negeri 1 Kulisusu pada materi larutan elektrolit dan non elektrolit. Penelitian ini merupakan penelitian Research & Development (R&D) dengan menggunakan model pengembangan 4D yang diterapkan tanpa menggunakan tahapan diseminasi. Sampel dalam penelitian ini adalah 56 peserta didik kelas X MIPA yang terdiri dari X Mipa 3 dan X MIPA 5 SMA Negeri 1 Kulisusu. Bentuk instrumen yang digunakan adalah tes diagnostik tiga tingkat untuk 20 butir soal. Hasil penelitian menunjukkan bahwa instrumen tes yang dikembangkan dinyatakan valid dengan nilai rata-rata kevalidan sebesar 87%. Butir dinyatakan reliabel dengan koefisien reliabilitas yang tinggi yaitu sebesar 0,74. Tingkat kesukaran soal terdiri atas 3 butir soal mudah, 10 butir sedang dan 7 butir sukar. Tetapi memiliki daya pembeda yang tergolong sangat baik membuka 5 butir, baik membuka 9 butir, cukup membuka 4 butir dan tidak membuka 3 butir. Profil miskonsepsi peserta didik menujukkan bahwa sebanyak 4 peserta didik mengalami miskonsepsi kategori tinggi, sebanyak 25 peserta didik mengalami miskonsepsi kategori sedang dan sebanyak 27 peserta didik mengalami miskonsepsi kategori rendah, dimana peserta didik mengalami miskonsepsi pada sub konsep sifat larutan elektrolit sebesar 35,71%, sub konsep kelompokkan solusi berdasarkan daya hantar listriknya sebesar 36,79% dan sub konsep jenis kimia dan sifat elektrolit suatu zat sebesar 37,

Experiments have been successfully carried out to react with lactic acid and 1,4-butanediol, tin (II) chloride dihydrate (SnCl2.2H2O), chloroform, methanol, liquid nitrogen, nitrogen gas, and silicone oil at various concentrations. The objective exists to synthesize polylactic acid by forming polylactic acid diol (PLA-OH) via a direct polycondensation reaction of lactic acid and 1,4-butanediol in a glass reactor following a specific reaction scheme. Synthesis was carried out using different amounts of reagents according to the predetermined mole ratio of lactic acid (AL) and 1,4-butanediol (BD). The FTIR, 1H NMR, and GPC analyses that characterized the PLA-OH revealed its physicochemical characteristics. The FTIR and 1H NMR characterization results show new absorption peaks and a shift in PLA-OH absorption peaks. It indicates that a bond has been formed from the reaction between lactic acid molecules and 1,4-butanediol to produce PLA-OH. From the spectrum analysis, it can be concluded that the structure of the synthesized PLA-OH has four different proton environments (there are four different peaks in the spectrum). The peaks originate from the protons in methylene (-OCH2CH2CH2CH2O), internal methine (-O-CH-), and methine at the end of the PLA-OH chain, as well as proton peaks in methyl (H3C-). The characterization results with GPC showed that the tendency to increase Mn PLA was directly proportional to the increasing amount of lactic acid in the PLA chain
