Abstract A feasibility analysis of tertiary treatment for Organic Liquid Agricultural Waste is presented using filamentous algae belonging to the genus Cladophora sp. as an alternative to chemical tertiary treatment. The main advantages of tertiary treatments that use biological systems are the low cost investment and the minimal dependence on environmental variables. In this work we demonstrate that filamentous algae reduces the nutrient load of nitrate (circa 75%) and phosphate (circa 86%) from the organic waste effluents coming from dairy farms after nine days of culture, with the added advantage being that after the treatment period, algae removal can be achieved by simple procedures. Currently, the organic wastewater is discarded into fields and local streams. However, the algae can acquire value as a by-product since it has various uses as compost, cellulose, and biogas. A disadvantage of this system is that clean water must be used to achieve enough water transparency to allow algae growth. Even so, the nutrient reduction system of the organic effluents proposed is friendly to the ecosystem, compared to tertiary treatments that use chemicals to precipitate and collect nutrients such as nitrates and phosphates.

Kegiatan pengabdian pada masyarakat merupakan salah satu cara supaya mahasiswa Universitas Trilogi memiliki keterampilan bermasyarakat. Khalayak  sasaran  dari  pengabdian  ini  adalah  masyarakat RW 09 di  desa Ciasihan. Kegiatan pengabdian  telah  dilaksanakan  pada  tanggal  11 Agustus-11 September yang  bertempat  di desa Ciasihan Kecamatan Pamijahan Kabupaten Bogor, dengan diikuti oleh seluruh masyarakat RW 09. Dari  hasil  evaluasi  diperoleh  hasil  dan  manfaat  dari  kegiatan  pengabdian  ini diantaranya adalah meningkatkan motivasi masyarakat akan pentingnya koperasi, dan pentingnya akan pemanfaatan sampah organik  menjadi pupuk. Kegiatan pengabdian  ini  berjalan  dengan  lancar,  karena  berbagai  pendukung  terutama  partisipasi peserta yang cukup antusias dan berpartisipasi aktif dalam kegiatan pembentukan koperasi.. Tujuan  kegiatan  pengabdian  kepada  masyarakat  ini,  yang  dilaksanakan melalui kegiatan pembentukan koperasi adalah memotivasi masyarakat akan pentingnya koperasi, dan pentingnya akan pemanfaatan sampah organik  menjadi pupuk. Selain itu, Pengabdian Pada Masyarakat ini merupakan wahana bagi mahasiswa Universitas Trilogi untuk mengabdikan keilmuannya.Kata Kunci: Pembentukan Koperasi, Masyarakat RW 09Community service activities are one way for Trilogy University students to have social skills. The target audience of this service is the community of RW 09 in Ciasihan village. Community service activities were carried out on 11 August-11 September in Ciasihan Village, Pamijahan District, Bogor Regency, followed by all RW 09 people. From the results of the evaluation, the results and benefits of this service were obtained, including increasing community motivation for the importance of cooperatives, and the importance of using organic waste into fertilizer. This service activity went smoothly, due to various supporters, especially the participation of enthusiastic participants and actively participating in cooperative formation activities.

Energy is one of the main pillars of the state’s economy, which is currently facing serious problems due to depletion of mineral energy resources and the threatening environment. As a result, presently around the world there is a rapid growth and development of energy-efficient technologies and the use of renewable energy sources (RES), providing an increase in energy resources, as well as environmental and social effects. One of the most relevant and promising areas of renewable energy development is the disposal and processing of organic waste in biogas plants, and this is particularly relevant in agricultural regions. In this regard, this paper considers the state and prospects for the development of bioenergy in agricultural regions of Uzbekistan, where half of the population of the republic lives. The potential of organic waste from livestock and poultry farming of the agricultural sector was determined, and it was revealed that the use of biogas plants for the disposal of manure and litter is clearly a profitable production and requires close attention from rural producers. The introduction of biogas technologies for the bulk of agricultural producers is an urgent task, that will ensure not only a solution to the waste problem, but it will also provide a solution to energy, agricultural, environmental and social problems in rural regions of the republic.
