Abstract

Jompo river is one of many tributaries in Jember regency has become one of water sources for residents nearby to meet their daily needs. People activities may lead to the emergence of pollution in Jompo river in long term. The measurement needs to determine water quality of the river. The research site ranged from Patrang to Kaliwates district with six nodes and covered a distance of 625 m. Based on the data analysis, average value of water quality in the river was characterized by 67 mg/l TSS (Total Suspended Solids), 72 mg/l TDS, pH at 6.73, 8.34 mg/l DO, 1.20 mg/l BOD, and EC at 145 µmhos/cm. Based on Government Regulation No. 82 of 2001 and Electricity value, the water quality of Jompo river was included in Grade II criteria. Jompo River was appropriate to irrigation water.

Abstract

Indonesia's food needs continue to increase along with population growth. Land development for supporting the cassava food estate is one of the priority programs of the central and regional governments. The purpose of this study was aimed at determining the need for power tiller for land management based on land area. This research was carried out at the planned location of the cassava plantation in Gunung Mas Regency, Central Kalimantan in 2020. The data on the land area planned was determined from a topographic map, while the tractor needs were obtained from the calculation of field capacity. The area of land suitable for cassava cultivation is 1227.57 ha which is divided into 25 blocks. The basis for the number of tractors as power tiller needed is determined from the time of tillage work so that it requires working capacity variables, including data on land area, work speed, and width of the plow implement. The plow studied in this study used 2, 3, 4, and 5 blades of disc plows. The need for a tractor with a 5-blade disc plow is 2 tractors that work fully and take turns cultivating an area of 1227.57 ha in the span of one cassava cultivation period (7-8 months). If the disc plow used is less than five blades, it will affect the working width of tillage, so the work time will be longer and the need for power tiller will increase. Keywords:   Cassava, Disk Plow, Food Estate, Power Tiller, Tractor

Abstract

Lumajang Regency, especially Bades Village, is one of the central managements of coastal and marine areas in East Java Province. One of the fishermen groups in Bades Village is the Mina Dampar Fishermen Group. Until now, these fishermen groups have not been able to utilize coastal areas for small-scale people's ponds due to limited knowledge of intensive shrimp farming technology, limited access to capital, and limited market information. This Technical Guidance aims to broaden horizons and introduce vannamei shrimp farming technology to fishermen who are members of the Mina Dampar group. This technical guidance activity was carried out at the Fish Landing Base in Bades Village and was targeted at the Mina Dampar Fishermen Group. The mentoring method used is the Participatory Rural Appraisal (PRA) method. This Technical Guidance aims to broaden horizons and introduce vannamei shrimp farming technology to 10 fishermen who are members of the Mina Dampar group. This technical guidance consists of outreach activities and field orientation. This activity shows that fishermen are interested in cultivating vannamei shrimp in Bades Village, especially freshwater vannamei shrimp cultivation. Cultivating freshwater vannamei shrimp can be a source of income for fishermen while doing housework.

Abstract

Urban development, population growth, high traffic jams, and intensive disaster events are indicators of changing the landscape of the eastern area of East Java. Investigating these changes is vital for planning and environmental protection in the future. This study examines changes in land use and land cover (LULC) during the past 50 years in the eastern part of East Java from 1972 to 2021. The changes are examined by contrasting four maps derived from Landsat images (1972, 1997, 2013, and 2021). The following are the main study procedures: (1) data inventory, (2) field survey, (3) image processing and classification, and (4) interpretation of LULC changes. With Google Earth Engine, all photos are downloaded (GEE). Landsat image classification was completed using the maximum likelihood algorithm with an overall Kappa accuracy of>85%. Eight (8) major classifications are therefore produced by the classification: (1) the pavement or urban area (PUA); (2) heterogeneous agricultural land (HAL); (3) bare soil (BS); (4) paddy field (PF); (5) open water body (OWB); (6) vegetation/plantation (VG); (7) shrubland (SL); and (8) wetlands (WL). In the areas with rapid development, the LULC change is more pronounced, i.e., Pasuruan, Jember, and Banyuwangi Regencies. LULC change in and near mid-regency and the rural regions comes next. Over the past fifty years, regional growth has resulted in increases in PUA (+4.4 percent), PF (+12.2 percent), and VG (+17.9 percent). On the other hand, the development has decreased SL, BS, and HAL by 5.8 and 15.9 percent, respectively (-13.1 percent ). LULC alterations for human activities have profoundly altered the natural landscape. Keywords:  East Java, GEE, Image Processing, Landsat, LULC
