Abstract

This study aims to determine the influence of the tourism sector and local economic development as seen from the number of tourist visits, the number of hotel rooms, and the number of MSMEs on the Regional Original Income (PAD) in Central Lombok Regency for the period 2002-2023. This study uses secondary data obtained from the Central Statistics Agency (BPS), the Cooperatives and SMEs Service, and regional financial reports for a certain period. The analysis method used is an associative quantitative approach using time series data. The calculation uses Multiple Linear Regression Analysis, Classical Assumption Test, and Hypothesis Test. The results of the study show that the variables of the number of hotel rooms and the number of MSMEs have a positive but not significant effect, while the number of tourist visits has a positive and significant effect on the regional original income in Central Lombok Regency. Simultaneous calculations show that the independent variables have a positive and significant effect on the regional original income of Central Lombok Regency with a large influence of 91.38% and the rest is influenced by other variables.

Abstract

Limited clean water is the main problem in Ujung Gagak Village. The community can use no groundwater because the water is brackish and salty, which is unsuitable for daily activities. This study aims to analyze the potential of the Karang Cave spring to be used as drinking water. This spring plays an important role in the life of the people of Ujung Gagak Village when the dry season arrives. Using the grab sampling method, raw water sampling at the Karang Cave spring. Pollution Status Index (IP) quality of 5.08 is included in the moderately polluted category. Then, raw water samples are taken and processed in the Reverse Osmosis (RO) system. Parameters that exceeded the quality standard were total coliform of > 24,000 CFU/100ml, salinity parameter of 0.33‰, turbidity of 1.98 NTU, and hardness of 320 mg/L. However, treating it in an RO system for drinking water is necessary. Laboratory test results for water quality after processing, several parameters experienced a significant decrease, for the parameter salinity to 0‰, turbidity to 0.74 NTU, and hardness to 99 mg/L, total coliform decreased by 108 CFU /100ml. The results showed that the RO system succeeded in removing salt up to 99.5% and reducing the Concentration of turbidity, hardness, and total coliform. It is suitable for drinking water, but if you want to drink it immediately, you can cook it first, considering that the total coliform is still above the required quality standard.
