Abstract

Since the middle of the 20th century, pesticide use has been a primary foundation of global agricultural development. However, the massive usage of pesticides can have detrimental impacts on human health and the environment, particularly in the aquatic ecosystem. This study determined the use of pesticides in the agricultural area of the Upper Citarum River Basin (UCRB); a crucial water resource on Java Island. A survey of 174 farmers was conducted in eight districts along the basin by using the random walk and quota sampling method. The questionnaire was designed to acquire data about the amount and types of pesticides used by farmers. Pre-survey was conducted to evaluate the feasibility of the questionnaire draft. The respondents’ answers were inputted into an equation to estimate the pesticide use per year. The survey results showed that 31 different pesticides were used for 21 types of crops. Profenofos and Mancozeb were the two most used pesticides, among all. The highest annual average used per hectare was reported for Chlorothalonil on tomato (32.2 kg/ha/year), followed by Mancozeb on corn (28.6 kg/ha/year), and Chlorpyrifos on chili (26.1 kg/ha/year). Overall, the pesticide use estimation in the study area is relatively high, with an annual average of 24.6 kg/ha/year. A comparison between prescribed and actual use on rice (representing more than 64% of the total surveyed area) showed that most pesticides are used in line with the prescriptions, but about a quarter is used in larger amounts than recommended. This comparison also revealed that some farmers use pesticides for rice that are not recommended for rice farming. In conclusion, the data presented in this study can be used to estimate pesticide emissions for environmental risk assessment and to support water quality monitoring, especially since public accessibility of pesticide information is commonly limited in Indonesia and other low- and middle-income countries.

Abstract

The Tanggul River in Surakarta City is a tributary that empties into the Bengawan Solo River. Domestic activities located on river borders can pollute with the waste generation. Therefore, managing waste sources such as storage and collection is crucial in waste management. This study aims to analyze waste management from river debris storage and collection around the study site. The technique used in this research is direct observation of the study area and performing a decision analysis for alternative processing. Decision support system has one model, namely Multi-Criteria Decision Making for environmental development. The activities for collecting and sorting river debris in the Tanggul River are not yet available. The existing river debros collection used a 7 cm diameter net that has been installed at the sluice gate of the Tanggul River. Considering aspects or criteria in implementing accommodation activities needs to be carried out before determining the best alternative. Therefore, several measures need to be considered in determining the container based on SNI 19-2454-2002 concerning Operational Procedures for Urban Waste Management and Minister of Public Works Regulation Number 3 of 2013. The collection activity in alternative 1 uses the Brute Boom system: Heavy Duty Containment Boom equipped with a galvanized weir mesh net attached under the boom. The collection activity in alternative 2 uses a floating cube. The floating cube is a cube-shaped Waste holder that can float in the river to effectively hold waste floating on the surface of the river body. It is imperative to prevent river pollution from activities by providing infrastructure for storing and collecting waste. However, it does not have a more significant impact, such as the Tanggul River to the Bengawan Solo River in Surakarta City.
