Abstract

ABSTRACT Bedadung River is used as sources of raw water by The Drinking Water Company (PERUMDAM) and also for agricultural irrigation. The urban segment of Bedadung River flows through Patrang, Sumbersari and Kaliwates Districts.  The burden of pollution in the Bedadung River is increasing along with community activities. Apart from anthropogenic activities originating from domestic waste, sources of pollution in the Bedadung River are also come from agricultural activities (fertilizer and pesticides), industrial activities, population growth, organic and inorganic waste, urban development and weak management systems. The research objectives were to identify the behavior and perception of the urban segment communities on water pollution at Bedadung River. This study used primary data from survey using 400 respondents and secondary data from some institutions. Survey showed that majority of the respondents through away garbage to channel and river, however for feces disposal, 75% of the communities already had toilets. Based on community perceptions the current status of the Bedadung River is 58% polluted, 7% unknown, and 36% is good. This perception is based on Bedadung River water conditions such as the presence of garbage, water clarity and water odor. In order to maintain the environmental quality of the Bedadung River, the community and related stakeholders have carried out river cleaning activities on a sustainable basis. This preliminary study is expected to provide preliminary information on managing community-based river water quality in a sustainable manner.Keyword: Bedadung Watershed; society; environmental quality ABSTRAKSungai Bedadung segmen perkotaan digunakan sebagai air baku Perusahaan Umum Daerah Air Minum (PERUMDAM) dan juga berfungsi untuk irigasi pertanian.

Abstract

Peternakan burung puyuh merupakan salah satu sumber pendapatan bagi masyarakat khususnya di Desa Besuk Kecamatan Tempeh Kabupaten Lumajang. Beberapa keterbatasan yang dihadapi oleh mitra peternak burung puyuh yaitu pemanfaatan limbah kotoran burung puyuh yang belum memiliki nilai ekonomis, mahalnya harga dan terbatasnya konsentrat untuk burung puyuh, serta belum adanya teknologi tepat guna dalam pengembangan produk samping dari peternakan burung puyuh secara berkelanjutan. Salah satu upaya penyelesaian permasalahan yang dihadapi adalah melakukan pengembangan ekonomi sirkular secara sinergis melalui pendampingan biokonversi limbah kotoran ternak dengan memanfaatkan larva black soldier fly (BSF). Tujuan kegiatan pendampingan dalam pengabdian masyarakat ini adalah melakukan penanganan limbah kotoran burung puyuh berbasis larva BSF dan upaya pemanfaatan larva BSF sebagai bahan tambahan pakan ternak burung puyuh afkir. Kegiatan pendampingan dikemas dalam Program Kuliah Kerja yang dilakukan oleh beberapa mahasiswa tingkat sarjana dari Jurusan Teknik Pertanian Universitas Jember. Tahapan pendampingan terdiri atas praktik budidaya larva BSF menggunakan media tumbuh kotoran burung puyuh, pemberian larva BSF untuk pakan ternak tambahan, dan kalkulasi pemberian pakan ternak berbasis larva BSF terhadap produksi telur burung puyuh afkir. Hasil kegiatan menunjukkan bahwa penanganan limbah kotoran burung puyuh menggunakan larva BSF mudah diaplikasikan serta mampu memberikan nilai tambah terhadap kegiata peternakan puyuh yaitu mengurangi pemakaian pakan ternak buatan, serta kotoran maggot dapat dimanfaatkan sebagai campuran pupuk organik. Adapun produksi telur puyuh afkir yang menggunakan pakan buatan dan pakan maggot BSF tidak menunjukkan perbedaan signifikan. Secara umum, penggunaan larva BSF pada peternakan puyuh mampu mendukung penerapan ekonomi sirkular sebagaimana yang diinginkan sesuai tujuan pendampingan ini.

Abstract

The variety of community activities in urban areas and a poor domestic sewage system are thought to affect the water quality of the Bedadung River. The high level of river pollution is caused by the high amount of polluting waste that enters, thus increasing the pollution load. Point source pollutant sources are sources of pollutants originating from certain sources that can be identified directly, such as domestic waste disposal, industrial activities, and others. Organic pollutants from domestic waste that enter the river can reduce the dissolved oxygen concentration in the river which can affect the quality of river water. The quality of water from pollutants can be indicated by knowing the concentration of the oxygen content in the water. To find out, it is necessary to measure the amount of BOD (Biochemical Oxygen Demand). The BOD value can be used as an index number to measure the level of pollutants from waste in a water system. In addition, changes in land use are also the impact of population growth and increased human activity. Land-use changes that ignore the principles of ecosystem sustainability tend to harm the environment, including a decrease in water quality. This study was conducted to determine the potential point source pollution load of Bedadung River in the Urban Area using information about the Bedadung River both spatial data and pollutant water quality (BOD) data. All data is combined and processed using Geographical Information Systems (GIS) technology. The data were analyzed and plotted into a map depicting the distribution of potential point source pollutant loads in the Bedadung River Urban Area Segment. The results of the analysis of land cover pollutant source areas based on the boundary include rice fields of 18.97%, fields of 5.98%, gardens of 12.85%, rivers of 12.25%, and settlements having the largest land area of 49.96% of the total area of the study area. The results of the calculation of the potential point source pollution load showed that the highest potential pollution load value was in the Kaliwates village of 13.966 kg/day, the lowest was in the Antirogo village of 0.004 kg/day and the total point source pollution load was 36.31 kg/day.

Abstract

Organic robusta coffee cultivation in Klungkung Village can cause environmental pollution and has the potential to produce greenhouse gases (GHG) due to inefficient use of energy. Upstream processes or gardens use organic fertilizers without proper knowledge. Meanwhile, downstream or processing uses technology and produces waste that is not yet environmentally friendly. This study aims to determine how much impact the processing of organic robusta coffee can make, so that the product can be said to be feasible as an environmentally friendly product. The method used in this research is Life Cycle Assessment (LCA) which has stages of determining goals and scope, life cycle inventory, life cycle impact assessment and interpretation. Processing of organic robusta coffee products produces a GWP of 21,2768 kg CO2-eq and the efficiency of energy use shows a NER value of 0.02 and a NEV of -153.94. The recommended alternative improvement is the use of coffee horn skin which is processed into briquettes as a substitute for LPG fuel in the roasting process. If the alternative recommendations are implemented, it can reduce the GWP value to 20.4374 kg CO2-eq and increase energy use efficiency to a NER value of 1.09 and NEV of 9.86. The environmental impact resulting from this research is the amount of greenhouse gases (GHG) resulting from the organic robusta coffee production process, if not repaired, it will pollute the surrounding environment.

Abstract

Bedadung River is one of the strategic rivers located in the Bedadung watershed in Jember Regency. One of the utilization of Bedadung River is used as one of the raw water sources for the PDAM Jember Regency. A large number of population activities around the river can increase the amount of domestic waste entering the river. This study aims to find out the estimated changes in water quality of Bedadung River based on water quality status. This study uses the pollution index method to determine water quality status and estimation using the simple linear regression model. The measurement results obtained the condition of the water quality status of Bedadung River in 2016-2019 classified as a category of lightly polluted. Indicated by the value of the pollution index in order 3,500; 2,072; 2,117; 1,929 ranges from 1.0 to 5.0. Based on the estimated data using simple linear regression obtained equation model Ŷ = 104.87 -0.0012X + ei. The result of the equation shows that the variables of population growth are negatively related to changes in the water quality of the Bedadung River. Where each population growth increases by 1 unit, the pollution index will decrease by -0.0012. Conversely, if the pollution index increases by 1 unit, then population growth will decrease by 104.87. Based on the coefficient of determination R² = 0.6945 shows that the change in water quality of Bedadung River by 69.45% is influenced by population growth and the remaining 30.55% is influenced by other variables. Keywords: Water Quality, Bedadung River, Pollution Index, Simple Linear Regression ABSTRAK Sungai Bedadung merupakan salah satu sungai strategis yang terletak di daerah aliran sungai Bedadung di Kabupaten Jember. Salah satu pemanfaatan Sungai Bedadung adalah sebagai salah satu sumber air mentah untuk PDAM Kabupaten Jember. Banyaknya aktivitas penduduk di sekitar sungai dapat meningkatkan jumlah limbah domestik yang masuk ke sungai. Penelitian ini bertujuan untuk mengetahui perkiraan perubahan kualitas air Sungai Bedadung berdasarkan status kualitas air. Penelitian ini menggunakan metode indeks pencemaran untuk menentukan status kualitas air dan estimasi menggunakan model regresi linier sederhana. Hasil pengukuran menunjukkan bahwa kondisi status kualitas air Sungai Bedadung pada tahun 2016-2019 tergolong dalam kategori sedikit tercemar. Hal ini ditunjukkan oleh nilai indeks pencemaran sebesar 3,500; 2,072; 2,117; 1,929 yang berkisar antara 1,0 hingga 5,0. Berdasarkan data yang diestimasi menggunakan regresi linier sederhana, diperoleh persamaan model Ŷ = 104,87 -0,0012X + ei. Hasil dari persamaan tersebut menunjukkan bahwa variabel pertumbuhan penduduk berhubungan negatif dengan perubahan kualitas air Sungai Bedadung. Artinya, setiap peningkatan pertumbuhan penduduk sebesar 1 unit akan mengakibatkan penurunan indeks pencemaran sebesar -0,0012. Sebaliknya, jika indeks pencemaran meningkat sebesar 1 unit, maka pertumbuhan penduduk akan mengalami penurunan sebesar 104,87. Berdasarkan koefisien determinasi R² = 0,6945 menunjukkan bahwa perubahan kualitas air Sungai Bedadung sebesar 69,45% dipengaruhi oleh pertumbuhan penduduk dan sisanya sebesar 30,55% dipengaruhi oleh variabel lain. Kata Kunci: Kualitas Air, Sungai Bedadung, Indeks Pencemaran, Regresi linier sederhana
