The flow of water in the sub-soil tends to transport fine soil particles to other places. This happens, especially during heavy rains, where rainwater that seeps into the ground, flows carrying fine particles into the pond, and causes the soil surface to subside in certain parts. This encourages a study to be carried out to apply KOBEL bricks to overcome this. KOBEL bricks have 2 holes with a diameter of 5 cm, when arranged, they will form a pipe that can regulate the flow of water, so it does not carry fine grains that flow or are eroded. The simple concept of providing available water flow can prevent soil erosion and minimize the negative impact on soil subsidence due to water flow in the soil. KOBEL bricks are made from soil base material that is pressed up to 62.5%, applied as soil improvement, so that the soil surface becomes stable and does not sink anymore. From the results of the application of the KOBEL brick for the subsided soil surface, it turns out that the surface is no longer sinking. It can be concluded that the use of KOBEL bricks which is very easy to do and requires very low cost can be used to overcome soil subsidence due to water flow in the soil.

The development of the clean water sector in rural areas is intended to help rural communities who do not have access to safe and decent clean water, especially the poor. Clean water facilities that have been built, then managed by the community with the establishment of a village institution called LPPAM (Drinking Water User Management Agency). Service reliability is indicated by the quality and continuity of water received by the water customer community. To test these allegations, research has been conducted using field observation techniques, interviews, and filling out questionnaires. The results showed that rural clean water management in Tonggo Village, for the majority of service aspects, was still in the category of less satisfied, and the quantity aspect was still insufficient. For water, quality is tasteless, colorless, and odorless. As for the continuity aspect, it still cannot flow 24 hours for some parts of the region in Tonggo Village. It is hoped that with this research, LPPAM - Tonggo will learn more or take courses and training to get community-based management so that they can work and serve the community better.

Kuliah Kerja Nyata (KKN) Mandiri Universitas Flores tahun 2021 di selenggarakan pada tanggal 02 - 31 Agustus 2021. Memiliki tema yaitu, “Masyarakat Tangguh Dalam Menghadapi Covid-19 Bersama KKN Universitas Flores” dan sub tema “Pengelolaan dan Perancangan Sarana dan Prasarana Desa/Kelurahan Berbasis Lokal”. Lokasi di laksanakan di Desa Raporendu, Kecamatan Nangapanda, Kabupaten Ende, Provinsi Nusa Tenggara Timur. Kegiatan KKN ini hasil kerja sama pemerintah desa setempat, masyarakat, mahasiswa dan Dosen Pembimbing Lapangan (DPL). Tujuan kegiatan ini agar mahasiswa bisa menerapkan apa yang mereka peroleh dibangku kuliah, dan  mendapat  pengalaman  belajar  dengan ikut terlibat bersama  masyarakat  secara  langsung,  melalui masalah yang ditemukan dan mencari solusinya. Ada beberapa masalah yang dijumpai dilokasi, sehingga perlu adanya usaha bersama untuk mengurangi atau mengatasi hal tersebut. (1) minimnya fasilitas yang menunjang untuk menekan penularan virus Covid-19 di Desa Raporendu, maka dibuatkan wastafel atau tempat cuci tangan didepan Kantor Desa untuk pegawai kantor atau tamu/warga setempat yang datang berkunjung, (2) Pembuatan bak sampah dari bahan batako untuk mengatasi pencemaran lingkungan akibat sampah yang berserakan, (3) memperbaiki instalasi listrik di pelabuhan, (4) pembuatan gapura dari bahan bambu lokal, (5) kerja bakti membersihkan rumah ibadat dan lingkungan desa. Dari hasil kegiatan ini diharapkan dapat memberikan manfaat bagi pemerintah dan masyarakat setempat, dan dapat bekerja sama untuk kegiatan KKN tahun selanjutnya. Kata Kunci: KKN Mandiri, Desa Raporendu, Wastafel, Bak Sampah, Kerja Bakti

Rainwater is a very potential water resource. Managing rainwater can provide water availability for households and family farms, which in turn can improve food security. The available water can also be used as a micro hydro power plant (PLTMH). This encourages research to determine sustainable rainwater management policies. First, it is important to analyse the climatology of the area to determine the characteristics of rainfall, namely the potential and distribution of existing rainfall patterns, so that the available water potential can be determined. Second, an investigation regarding the suitability of the soil for crops in the area is based on the Agro Ecological Zoning method, which the crop length growth period was also considers to find the efficient planting date. This will ensure optimal crop yields with efficient water requirements. Third, further study of the applied rainwater management system is related to the potential for renewable energy. Finally, it can be concluded that by managing the potential for rainwater in Rukuramba village, the water needs for households, family farming, and energy are available. Fulfilling the needs of water for households, agriculture and energy has made Rukuramba village independent and prosperous due to a significant economic increase.
