Abstract.The main objectives of this study was to investigate the potential of lateritic soils deposit South Sulawesi, Indonesia as a precursor for Na-poly(ferro-sialate) geopolymers. The samples of laterite soils were taken from three different regions, namely Sidrap, Bone, and Gowa regency. The soil was clean, grounded, sieves 200 mesh, and dehydroxylated at 750 o C for 2 hours. The x-ray fluorescence (XRF) and energy dispersive spectroscopy (EDS) were used to examine the chemical compositions of the soils. The geopolymers was synthesized through alkali activation method by adjusting the molar oxide ratios of SiO 2 /(Al 2 O 3 +Fe 2 O 3 ), Na 2 O/SiO 2 and H 2 O/Na 2 O in accordance with the chemical compositions of the soils. The functional groups of the resulting geopolymers were examined by using Fourier Transform Infra-Red (FTIR). The structure and phase of the resulting material were studied by using x-ray diffraction (XRD). The surface morphology of geopolymers was studied by using scanning electron microscopy (SEM). The mechanical strength of the materials was examined through compressive strength measurement. The results of this study showed that high strength Na-poly (ferro-sialate) geopolymers were successfully produced and characterized.

Background: Low knowledge of effective cough ethics can lead to uncontrolled transmission of the corona virus. Knowledge of effective cough ethics can be improved by conducting health education. Media is needed when conducting health education to facilitate the delivery of information. This means that people who serve their activities return in the Covid-19 situation, but still pay attention to health protocols. Coughing is a reaction that occurs in the cells in the airways behind the esophagus being irritated. This research is also given in a pre-test and post-test design. Aims: To provide respondents with an understanding of the ethics of effective coughing. Methods: In this outreach using descriptive methods using pre-test and post-test questionnaires. Results: From the counseling that has been done to respondents in Solonsa Village, there were 8 respondents who had low knowledge (66.66%) and 4 respondents with sufficient knowledge (33.33%). Conclusion: After counseling was carried out, there was an increase in the knowledge of respondents who had attended the counseling, which increased to 10 respondents (83.33%) with sufficient knowledge and 2 respondents (16.66%) who had sufficient knowledge.

Eggshells are household waste often found in Pitumpidange Village and thrown away by the community. Eggshells consist of 94% CaCO3, 1% MgCO3, and 1% Ca3PO and the remaining 4% is organic matter which can be processed into environmentally friendly toothpaste. Apart from eggshells, another natural ingredient in toothpaste is betel leaf. It contains essential oils, catechins, and tannins which are polyphenol compounds and can act as an antiseptic and prevent the biological activity of caries-causing bacteria such as Streptococcus Mutants. The purpose of this Community Service is to overcome partners' problems, namely the accumulation of eggshell waste which is a crucial problem at the Karang Taruna Group in Pitumpidange Village. The program also increases the empowerment of partners through the manufacture of environmentally friendly toothpaste by utilizing the village's potential in the form of eggshells and betel leaves. Ten people are participating in this program. The community service implementation method consists of three main stages: counseling, training, and mentoring. A questionnaire containing statements about the partner's knowledge and skills after the program was implemented used to find out the partner's response to the program. The results of the community service activities show that the partners of the Karang Taruna group in Pitumpidange Village can process eggshells combined with betel leaves into environmentally friendly toothpaste. Therefore, this community service supports the implementation of village SDG goals and supports Indonesia in the G20 group (Group of Twenty) in utilizing the natural surroundings through green innovation.

Desa Pitumpidange merupakan salah satu desa yang terletak di Kecamatan Libureng, Kabupaten Bone, Provinsi Sulawesi Selatan. Desa Pitumpidange terkenal sebagai sentra pemasok telur di Kabupaten Bone, termasuk penyedia telur untuk pedagang gorengan dan kue di kecamatan Libureng, Patimpeng, dan Kahu. Produk olahan dari pedagang dan penjual kue menghasilkan cangkang telur yang cukup banyak. Selain kulit telur dari konsumsi rumah tangga. Dari hasil observasi didapatkan data bahwa hampir setiap rumah di Desa Pitumpidange menjadikan telur sebagai makanan untuk konsumsi hewan setiap harinya. Oleh karena itu, dengan adanya PKM-PM ini diharapkan masyarakat dapat bersinergi mengolah limbah cangkang telur dari kombinasi daun sirih menjadi produk yang memiliki nilai ekonomis yaitu sebagai pasta gigi. Selama ini mitra belum mengetahui bahwa limbah cangkang telur dan daun sirih dapat diolah menjadi produk yang memiliki nilai ekonomis dan mengandung nutrisi yang berguna dalam memperbaiki kerusakan yang terjadi pada gigi. Oleh karena itu, mitra sangat antusias menjadi mitra dalam program PKM-PM ini karena memiliki ekspektasi komersial melalui inovasi produk menjadi produk pasta gigi sehat dari limbah cangkang telur dan daun sirih.

Desa Buriko merupakan salah satu desa di Kecamatan Pitumpanua, Kabupaten Wajo, Provinsi Sulawesi Selatan. Pencarian utama masyarakat adalah disektor perikanan dan perkebunan. Potensi desa merupakan segala sumber daya alam maupun sumber daya manusia yang terdapat serta tersimpan di desa. Dimana semua sumber daya tersebut dapat dimanfaatkan bagi kelangsungan dan perkembangan desa. Tujuan kegiatan ini untuk membantu percepatan pembangunan diwilayah pedesaan bersama dengan memanfaatkan potensi desa dan Meningkatkan Pertumbuhan Ekonomi Desa. Membangun Desa dengan Inovasi merupakan Bentuk Kegiatan Program kerja KKN dan pengabdian yang mengasah softskill, kemitraan dan kolaborasi lintas disiplin serta leadership mahasiswa dalam mengelola potensi diwilayah pedesaan. Metode pelaksanaan yang dilakukan dalam kegiatan seminar kebangkitan potensi desa yaitu metode demonstrasi dan metode diskusi.
