Abstract

Utilization of water for agricultural purposes is the highest, reaching 70% of the total utilization of water resources globally. In the Glundengan Irrigation Area, Wuluhan District, Jember Regency, with an area of ​​4996 ha, irrigation water is taken from the Bedadung River, and the excess water is discharged from the Glundengan Irrigation Area to the Bedadung River. This encourages research on the quality of irrigation water in these irrigation areas. This study aims to analyze the quality of irrigation water, especially the elemental content of potassium in the Glundengan irrigation channel. In the analysis of the quality of irrigation water, temporary sampling was carried out at two points, namely in the primary channel which carries water to the paddy fields and in the drainage channel which removes excess water from the irrigation area. The temperature and pH parameter analysis method used the standard SNI 6989.57:2008, while the K parameter analysis was carried out in the CDAST laboratory using the Flame Photometry-AAS method. The results of the analysis are compared with the water quality standards in Government Regulation No. 82 of 2001 (PP 82/2001): Management of Water Quality and Control of Water Pollution. The results of the analysis show that the temperature parameters in the primary and exhaust channels are 24°C respectively. The pH parameters in the primary and sewer channels were 7.5 and 7.2, respectively. The K parameters in the primary and sewer channels were 0.00593 mg/l and 0.00745 mg/l respectively, these figures were relatively small. These three parameters meet the water quality standards of Class II according to PP 82/2001.

Abstract

In the Ijen sub-district, care must be taken to avoid overlapping uses of PTPN XII-owned plantations, resident fields, and the medium-voltage power distribution network. To lessen the interference factor in the distribution of electricity, the proper power distribution path must be chosen. The contact between trees and lightning is one of the variables that disturbs the distribution pathway. It is well known that the Jampit distribution substation in the Ijen district is situated in a region with plantations and private fields, making it susceptible to lightning and contact with trees. The position of distribution substations, medium-voltage overhead lines, and the location of energy users are among the issues examined in this study. In order to create a map of the electricity distribution network at Jampit distribution substations that pass through agricultural land and plantation areas, ArcGIS is used to help process spatial data including regional administration data, type of conductor, power capacity, distribution substation poles and electricity users.

Abstract

Indonesia is an agrarian country with the agricultural sector playing a vital role in meeting basic needs and boosting the social, economic, and trade sectors. One of the widely cultivated crops is sugar cane, which is the raw material for sugar. Sugar is a strategic commodity and plays a vital role in the economy and community food security. The demand for sugar is enormous, but sugar production is still unable to meet all of this demand. Indonesia continues to strive to achieve sugar self-sufficiency. Therefore, the author is interested in conducting research related to how to forecast Indonesian sugar production for 2025-2030 using the ARIMA method? And what strategies are there to achieve Indonesian sugar self-sufficiency in 2030? The results obtained are: forecasting Indonesian sugar production can be done using the ARIMA (2,2,0), with an Sun Square Residuals value of 0.210136. Indonesia's sugar production forecasts from 2025 to 2030 are: 2.497 million tons, 2.450 million tons, 2.601 million tons, 2.635 million tons, 2.646 million tons, and 2.755 million tons, respectively. To achieve sugar self-sufficiency in Indonesia by 2030, the Indonesian government needs to add 1.19 million hectares of new land for sugarcane farming.
