Analisis daya tampung beban pencemaran sungai bedadung Jember menggunakan software wasp
No full textThe distribution of pollution sources from domestic, agricultural, and industrial activities has the potential to reduce the water quality of the Bedadung River, thereby negatively impacting its self-purification. The aim of this research is to model the parameters, specifically the values of Biochemical Oxygen Demand (BOD) and Total Suspended Solid (TSS), and to determine the river's capacity to carry the pollution load using the Water Quality Analysis Simulation Program (WASP). The input parameters for this study include BOD, TSS, and water discharge data collected at 21 monitoring points along the Bedadung River, with the river water sampling technique employing the grab sampling method. The output validation of the modeling is assessed using the Root Mean Square Error (RSME) equation, and the research results indicate that the water quality modeling with WASP software effectively reflects the dynamics of BOD and TSS parameters in the Bedadung River, as supported by an average output validation value of 9%. The pollution load capacity values for the Bedadung River in the Patrang - Ajung segment are found to be 361.48 kg/day for BOD and 5368.31 kg/day for TSS. The positive values suggest that the Bedadung River still has the capacity to naturally degrade organic pollutants

Cultural landscape function of informal urban settlement in East Nusa Tenggara
No full textThe theme of cultural landscape function becomes very important along with the awareness to create a balance of ecological and social landscape functions in urban areas. Urban settlement strongly influences cultural function, both as a form of landscape and demographic characteristics. This paper aims to examine the existence of several important social values in urban settlement landscapes and the role of landscape features in influencing social values aspects of informal residents such as social cohesion, recreation, sense of place, spiritualism, cultivation, and business activities. The research method used is a mixed quantitative and qualitative method by using observations, questionnaires, and interviews for data collection based on a sociological approach with community members. Questionnaire data were collected for further analysis in which the Spearman coefficient was used to examine the relationship between social values and landscape features. The results revealed that residents in Airmata and Manutapen have different percentages of social values in terms of their landscape features, and it can also be seen that the values of social cohesion, sense of place, and local business present a stronger relationship to landscape functions. These results show the importance of social values in informal societies as a potential approach to achieving sustainable landscape management

Pengembangan teknologi tangki pintar sebagai sistem peringatan dini bencana kekeringan
No full textAccording to the National Disaster Management Agency, in 2021 there were 5,402 incidents recorded, one of them being drought disasters. During the drought, the availability of clean water was minimal, so clean water assistance came from other areas. The problem that is often encountered in the field is delays in water distribution assistance due to sudden information and the location of the aid is in areas that are difficult to reach. This research developed a water tank technology equipped with a sensor to provide information about water availability, the location of the tank placement to speed up information on dropping water in drought areas. This technology uses the NodeMCU ESP8266 module which functions as a microcontroller, to provide sensor-based information that detects the quantity and quality of water as well as the location of the tank. This system is based on the Internet of Things (IoT) and Blynk Android which makes it easier for people to get information in real time. The water availability indicator is presented in a three-color graphical display, namely green is a safe sign (sufficient water), yellow is a warning sign (water is reduced), and red is a sign that water availability is running low and it is necessary to drop clean water. Other information presented is water quality parameters such as pH, TDS, turbidity, and temperature as well as the location of the tank. This technology supports the achievement of SDGs, namely goals number 6 (clean water and proper sanitation) and 11 (sustainable cities and settlements)
