The spread of the Corona virus (Covid-19) has recently become increasingly worrying, not only because of the inadequate handling due to the lack of mass rapid tests and the obstacle to the examination method using polymerase chain reaction (PCR) techniques. On the other hand, the habit of people who ignore and underestimate the spread of Covid-19 infection has become the main trigger for the increasing number of positive patients of Covid-19. This is even more worrying if the scale of our review is not only urban but also rural, where the potential for exposure to Covid-19 is getting bigger. Therefore, Halu Oleo University through the Integrated Community Service program (KKN) Thematic Prevention of Covid-19 has a big agenda of increasing public awareness both in cities and in rural areas who are very prone to exposure to Covid-19 to minimize the impact that occurs due to the spread of Covid-19. The purpose of this activity is to form a Covid-19 Disaster Resilient Village to anticipate its spread and impact in Southeast Sulawesi Province. This KKN is a multidisciplinary activity from various scientific fields involving students and lecturers from various departments. The method implemented is socialization as an effort to increase public awareness through social media that is easily accessed and understood by the community while still implementing social distancing and with strict health protocols, involving village and community officials. Another method is to collect data on the profiles of people who are vulnerable to exposure and have an impact on their health and economy, in addition to physical activities such as spraying with disinfectants at houses of worship. Other methods carried out include making booklets using local languages, and making tutorials on using Zoom and Google Meet online media meetings so that learning activities of school students and village officials can continue during the Covid-19 pandemic.The results of this KKN Thematic activity are expected to become a learning medium for students as part of the Merdeka Campus Program, building villages that are resilient to the Covid-19 disaster, maintaining the economy and community activities, and become a forum for community service for lecturers.

Pembangunan infrastruktur pertanian dianggap krusial karena selain potensi sumber daya alam yang besar dan beragam juga sebagai tempat masyarakat desa yang menggantungkan hidupnya Infrastruktur kawasan pertanian di Kecamatan Samaturu telah tersedia diantaranya jalan kabupaten dengan panjang 77,8 km, jalan usaha tani dengan panjang 13,7 km, prasarana irigasi, pintu air, serta gudang penyimpanan hasil pertanian dan pasar. Berdasarkan hasil penilaian menggunakan standar penilaian minimal Dinas Pekerjaan Umum, ketersediaan infrastruktur penunjang kawasan persawahan di Kecamatan Samaturu dengan nilai untuk akses infrastruktur 81,8%, nilai kesuaian infrstruktur sarana penyedian air 80,2 %, dan infrstruktur pendukung pertanian 75 %. Hasil persepsi petani terhadap infrastruktur pertanian berada pada kategori Baik pada Indeks 75 %-82 % dengan rata-rata 77,50%.

Soil investigation plays an important role in construction design. Adequate information regarding soil types and parameters are needed for a safe and economical foundation. However, limited budget often leads to inadequate soil investigations, and as a result, unknown soil parameters are estimated through correlations from the limited investigations that have been carried out. Correlations from SPT and CPT results are often used for design, but their applicability from location to location is questionable. This paper discusses the correlation of N-SPT values to CPT values in Wolo District, Kolaka Regency. The correlation was performed using linear regression analysis to obtain relationships between N-SPT and CPT. The three correlations obtained are N-SPT = 5.64 + 0.012qc, R2 value of 0.082; N-SPT = 5.93 + 0.01 qc – 0.095qf, R2 value of 0.125; N-SPT = 0.025qc + 0.341qf, R2 value of 0.455.

Sungai Wanggu terdapat pada Daerah Aliran Sungai (DAS) Wanggu dengan luas area sungai mencapai 4.537,73 Km2. Sungai Wanggu mengalir melalui 2 wilayah administrasi Provinsi Sulawesi Tenggara, yaitu Kabupaten Konawe Selatan dan Kota Kendari. Peristiwa sedimentasi umumnya terjadi pada hilir sungai. Check Dam adalah bangunan yang dibuat melintang sungai yang berfungsi untuk menghambat kecepatan aliran permukaan dan menangkap sedimen yang dibawa aliran air sehingga kedalaman dan kemiringan sungai berkurang. Penelitian ini bertujuan untuk mengetahui Berapa besar tampungan sedimen yang dapat tertampung pada check dam 5 sungai Wanggu dan Bagaimana efektivitas bangunan check dam 5 dalam mengendalikan sedimentasi untuk meminimalisir terjadinya banjir pada sungai Wanggu. Pengukuran efektifitas ini menggunakan aplikasi HEC-RAS dan metode endapan selama 1 Hari (23 jam). Hasil Pengukuran Volume tampungan check dam 5 sungai wanggu kota kendari ialah sebesar 594m³. Efektifitas Check Dam 5 Sungai Wanggu Kota Kendari menggunakan HEC-RAS 5.0.7 memperoleh hasil sedimentasi ketebalan 4 cm/hari dengan volume tampungan 594m³ atau sama dengan 0.0097m³ / hari. Sedangkan dengan metode endapan memperoleh hasil endapan juga senilai 0,0099 m³/ hari. Dari hasil yang sama kemudian dapat diketahui efektifitas check dam 5 sungai Wanggu adalah 22,3 tahun untuk analisis HEC-RAS 5.0.7 dan 21,9 tahun untuk metode endapan agar sedimmentasi tersebut memenuhi bak check dam 5

Artisanal and small-scale gold is known to be sources of mercury pollution. This mercury contamination occurs when gold is isolated by the amalgamation method, contamination occurs. Mercury pollution in small-scale artisanal gold mining in the Kulon Progo area of Yogyakarta, the lowest tailing content was 164.49 mg kg^-1, and the highest was 383.21 mg kg^-1. This value exceeded the quality standard stipulated by Indonesian Government Regulation 22 of 2021 of 75 mg kg^-1. The technology that can control pollution is stabilization/solidification (S/S). This research aimed to determine the optimum composition of the tailings mixture with tras soil. Variations in the design of tras soil with tailings were 100:0, 90:10, 80:20, 70:30, 60:40, 50:50, 40:60, 30:70, 20:80, and 10:90. The results showed that the optimum tras: tailings soil composition was 90:10, with a compressive test of 31 t m^-2. Toxicity Characteristic Leaching Procedure (<em>TCLP</em>) was 0.0033 mg L^-1 according to the quality standard of Indonesian Government Regulation no. 22, 2021, with a value of 0.05 mg L^-1. The compressive strength results follow the quality of the US EPA of 35 t m^-2.
