Abstract

Seawater intrusion is the entry of seawater into the land through the soil pores. Seawater intrusion harms sanitation activities. Surabaya constitutes a city with a high population density, which leads to high demand for water that is not proportional to the water input that cause seawater intrusion. Mitigation efforts to minimize the occurrence of seawater intrusion were by planting mangrove forests which act as coastal protection systems. The purpose of this study was to determine the water quality of the wells in Kenjeran and Rungkut, as well as to determine whether the presence of mangroves could affect the water intrusion mitigation. Samples were taken from 2 stations in Kenjeran and Rungkut with 3 sampling points and 3 repetitions. The parameters measured were consist of salinity, electrical conductivity, chloride, and total hardness. The samples of laboratory results were analyzed comparatively with the Kruskal Wallis test. It showed that the water in the coastal areas of Kenjeran and Rungkut was categorized as saline water with an average salinity value ranging from 3.1–7.2 ppt. Electrical conductivity values ??ranged from 6916-7993 mmhos/cm. Chloride values ??ranged from 1825-3848 mg/l. Total hardness values ??ranged from 320-1025 mg/l. Based on the values ??above, the quality of well water in both locations is classified as having experienced seawater intrusion. The existence of a mangrove forest landscape has no significant effect on mitigating seawater intrusion, this is presumably because the low percentage of mangrove cover (3.2%) cannot degrade seawater intrusion in Rungkut. Keywords: Groundwater; Mangrove Forest; Mitigation; Sea water intrusion; Surabaya.

Abstract

Taman Gumi Banten is an area that is utilized as a habitat for plant growth. An important background that supports Taman Gumi Banten is the preservation of rare plants classified as ceremonial plants, usada, and puspa dewata. This research aims to manage and conserve vegetation in the Taman Gumi Banten Besakih, as an effort to preserve ceremonial plants, usada, and puspa dewata. This research was conducted in Taman Gumi Banten Besakih with an area of 2 hectares, conducted for 3 months (May-July 2021). Sampling method with plot method. Primary data, both vegetation data and soil data were taken at the observation site, while secondary data were taken from the Karangasem BMKG office. Data analysis was carried out with vegetation analysis, namely the importance value index, diversity index and species distribution pattern, and vegetation rarity status based on PERMENLHK No. 20 of 2018. While soil data will be analyzed at the Soil Science Laboratory, Faculty of Agriculture, UNUD. The results concluded that the number of species found was 101 species, consisting of 2297 individuals, with low diversity and uniform distribution patterns. There are 2 species classified as rare, namely the kasna kasna (Anaphalis javanica) and gegirang tree (Leontopodium alpinum), soil conditions especially high levels of organic carbon and soil texture all sandy loam are very supportive of vegetation development, and the number of plants in Taman Gumi Banten has only been fulfilled 2297 individuals while the shortage of 2703 individuals (being pursued).
