Introduction: The use of antiseptics and disinfectants in daily health protocols has a consequence of changing the quality of wastewater to be toxic to microbes. As a result, microbiological wastewater treatment has the potential to not be processed properly. To solve the problem of disinfectant-rich wastewater, a plant-based treatment method can be useful, the implementation of which is a land treatment system for wastewater. Materials and Methods: The data collection method was carried out through the Mendeley Reference Manager, searching for articles online, and placing the terms “land treatment system”, and “disinfectant-rich wastewater”. The selected articles were up-to-date and had a significant relationship between the two terms. Results: This sanitation system can be a stretch of land and/or a pond of water, on which plants can grow and process. Normal concentrations of disinfectants for microbial elimination had no negative effects on the growth of various types of plants. Plants continue to live in the stress of water rich in disinfectants, as a condition of their ability to treat wastewater. The involvement of various wastewater treatment media makes evapotranspiration dry bed and evapotranspiration wet bed or wetland ponds capable of processing various pollutants. This approach can be implemented for on-site and off-site sanitation system. Conclusion: In this context, under conditions of enrichment of disinfectants in wastewater during the COVID-19 era, the land treatment system becomes feasible to solve the problem of changing the quality of wastewater.

Most of the total peatland area in Kalimantan Island and particularly in Central Kalimantan Province is suitable for agricultural development. This condition provides a great opportunity for the development of peatlands for the cultivation of traditional medicinal plants. The local society in their daily lives could not be separated from the inherent elements of tradition even though the development of science and technology is currently very fast. One of the traditional elements that are inherent at this time is the use of medicinal plants as a solution in treating various diseases. The research was conducted in Palangka Raya City, Central Kalimantan Province by conducting interviews to determine the type of selected medicinal plants and carrying out experiments for examining their ability to absorb carbon dioxide and to grow in peatland conditions. The results of the study of four types of traditional medicinal plants show that there is great potential for two types of plants, namely Semar Bags and Karamunting, whose implementation fulfills biodiversity in an agricultural land ecosystem.

This study aims to determine the internal and external factors that can influence the development of the tempe processing industry and find out alternative strategies that can be applied in developing the tempe industry made from soybeans from the peatlands of Palangka Raya City. Data analysis was carried out using SWOT analysis to evaluate strengths, weaknesses, opportunities, and threats in the strategic planning of a small industry for processing tempeh made from soybeans from peatlands. The results of the analysis show that there are several internal and external factors that influence the development of the tempe processing industry made from soybeans from the peatlands of Palangka Raya City. There are several alternative strategies that can be implemented in developing the tempe industry made from soybeans from the peatlands of Palangka Raya City, namely maintaining the quality of tempe starting from taste, texture, aroma, improving business capital, human resources and raw materials in order to meet the high demand for tempe.

Abstract:Pembelajaran Berbasis Proyek (Project Based Learning=PjBL) adalah metode pembelajaran yang menggunakan proyek/kegiatan sebagai media. Peserta didik melakukan eksplorasi, penilaian, interpretasi, sintesis, dan informasi untuk menghasilkan berbagai bentuk hasil belajar. Project based learning atau pembelajaran berbasis proyek merupakan model pembelajaran yang berpusat pada siswa untuk melakukan suatu investigasi yang mendalam terhadap suatu topik. Siswa secara konstruktif melakukan pendalaman pembelajaran dengan pendekatan berbasis riset terhadap permasalahan dan pertanyaan yang berbobot, nyata, dan relevan. Pada proses PjBL menuntut siswa untuk bekerja dan mendesain sendiri proyek yang akan dikerjakan. Tujuan kegiatan pengabdian ini adalah meningkatkan keterampilan mengajar dan literasi teknologi guru-guru SD di Desa Telangkah Kecamatan Katingan Hilir Kabupaten Katingan.  Dalam proses pengerjaaan proyek, siswa mengalami proses belajar dan membangun pengetahuannya sendiri. Hal tersebut sesuai dengan prinsip belajar sains yaitu learning by doing, yang mana sains dibangun dengan menemukan dan mencari sendiri melalui pengalaman nyata, sehingga membangun abstraksi seseorang dengan benda yang diciptakan sendiri.  

Kota Palangka Raya memiliki luas wilayah 2.678,51 km², jumlah penduduk 229.599 jiwa dan kepadatan penduduk rata-rata 85,72 jiwa/km².  Kota ini mengalami kemajuan cukup pesat sehingga berdampak terhadap semakin mahalnya harga tanah di daerah perkotaan. Salah satu kebijakan pemerintah untuk mengatasi permasalahan tersebut  dengan membangun rumah susun yang terjangkau bagi masyarakat menengah ke bawah. Aspek kenyamanan, sanitasi dan keamanan bagi penghuni rumah susun merupakan faktor utama yang menjadi perhatian. Pemerintah Kota Palangka Raya membangun rumah susun pertama tahun 2005 di Jalan Sesep Madu RT 02/RW 09 Kelurahan Palangka, Kecamatan Jekan Raya, Kota Palangka Raya dan mulai dihuni awal tahun 2010. Tulisan ini bertujuan untuk mengevaluasi sistem sanitasi di rumah susun Kota Palangka Raya. Metode yang digunakan dengan cara  observasi dan wawancara langsung terhadap pengelola dan beberapa penghuni rumah susun. Hasil observasi menunjukkan kondisi bangunan rumah susun kurang terawat, terkesan kumuh, kondisi hunian belum berfungsi secara optimal (pada lantai 5 terdapat 24 kamar tidak dihuni karena penerangan listrik diputus oleh Perusahaan Listrik Negara akibat menunggak), sistem sanitasi seperti air bersih tersedia tetapi air limbah, drainase dan persampahan tidak dikelola dengan baik.
