Abstract

To know the magnitude of sea water intrusion that occurred in Candidasa area need to be mapping by using Geo-electric Method. Geo-electric method is one Geophysical method that works by injecting an electric current into the ground and then measured the potential difference it generates. Based on the data of electric current and potential difference, resistivity will be obtained in the research area. The result of sea water intrusion mapping in Candi Dasa beach area indicates that sea water intrusion has occurred but not yet on the status of conspiracy. If groundwater extraction is not restricted, the level of intrusion will continue to increase. Contour resistivity indicates that there has been a sea water intrusion in the Candidasa Tourism Area in a mild status in the southeast area at a depth of 5-10 m. The measured rock resistivity values in the study sites ranged from 0.35 to 1800 ohm.m, the seawater intrusion criteria occurred at a resistivity of 0.5 - 30 ohm.m. The results of the study are expected to give policyholders input on sea water intrusion in Candidasa Tourism area so that appropriate policy steps can be taken.

Abstract

Abstrak. Tanah vulkanis merupakan suatu perlapisan tanah yang terbentuk oleh hamparan material letusan gunung berapi saat meletus. Tanah vulkanis biasanya tandus. Perlu waktu yang lama bertahun-tahun dan bahkan sampai berpuluh-puluh tahun untuk menumbuhkan kembali vegetasi (re-vegetasi) di daerah ini. Untuk itu perlu dicari suatu cara agar pada tanah yang semula tandus dapat sesegera mungkin ditumbuhi tanam-tanaman, sehingga tanah vulkanis menjadi produktif. Melihat kondisinya yang seperti ini dapatlah dianalisa bahwa masalah utama pada daerah tersebut adalah air dan cara mengelolanya. Di sini diberikan salah satu contoh untuk mencari air pada daerah tanah vulkanis tandus yaitu dengan Metoda Geolistrik. Dari hasil yang didapat bahwa walaupun bagian atasnya berupa tanah vulkanik tandus, namun di bawahnya masih terpendam akuifer-akuifer yang dapat disadap airnya. Setelah airnya didapat, airnya mestinya dikelola sehngga dapat dipakai oleh hewan maupun tumbuhan. Simbiosis antara hewan dan tumbuhan dapat mempercepat proses re-vegetasi pada daerah vulkanis tandus. Sebagai hasil studi, dapat dilihat pada beberapa daerah di Kabupaten Karangasem Bali.Kata kunci: Re-vegetasi, Tanah vulkanis tandus, Metoda Geolistrik, Air sumur

Abstract

Telah dilakukan penelitian tentang analisis karakteristik sumur bor. Penelitian ini merupakan suatu contoh penelitian tentang analisis karakteristik sumur bor di daerah batu karang dan tandus. Penelitian mengambil contoh di sumur RSPTN Universitas Udayana berlokasi di Jimbaran Badung Bali. Analisis yang dilakukan efisiensi sumur (Ew), faktor pengembangan sumur (Fd), perbaikan sumur (C) dan debit optimum (Qopt). Hasil penelitian didapatkan bahwa berdasarkan hasil pengukuran geolistrik, pada sumur bor memang ada akuifer. Sumur yang dibikin termasuk sumur yang efesien dengan tingkat efisiensi   84,71%. Ini berarti sangat efesien untuk pengambilan air. Sumur memiliki faktor pengembang 0,077864 hari/m3 Ini berarti sumur sangat baik untuk dikembangkan. Nilai C = 28994,2. Ini berarti apabila sumurnya ada kendala misalnya debitnya mengecil, maka sumur sulit dikembalikan menjadi seperti semula. Kapasitas jenis (Sc) rata-rata didapat: 0,0196908 m2/s, nilai ini lebih besar dari 0,005.  Ini berarti sumur memiliki produktifitas tinggi. Debit optimum (Qopt) = 0,00782 m3/s = 28,152 m3/jam. Drowdown optimum (Swopt) = 2,17 m. Nampak bahwa adanya keterbatasan kuantitas cadangan air. Uji sumur dengan debit konstan (0,00328 m3/s) telah dilakukan selama 7,5 jam ini berarti air sumur telah diambil 88,56 m3, tetapi sumur hanya mengalami penurunan permukaan air sebesar 22,2 cm secara konstan.

Abstract

Jembrana Regency located in Bali Province is one of the districts that have land good enough to be managed. However, some of the area still has the potential to be developed into agricultural land. Analysis of water availability, especially for rice plants, needs to be carried out to determine the time of planting rice, and aims to increase land productivity. The calculation method used is land water balance and plant water balance. The results of the calculation in the form of the percentage of water available for rice plants are used as a reference to determine the planting period in the form of rice planting patterns. From the results of the study, it was found that the decrease in the value of groundwater availability (GA) occurred due to a decrease in rainfall from June to August of around 9 bases to be below Field Capacity (FC). The GA value increases when the rainy season starts from January to April for period I and from September to December for Period II. Rice planting time in Jembrana Regency generally has 2 plantings because it is influenced by availability of groundwater and Rainfall.

Abstract

This research aims to examine the role of natural sciences in overcoming global environmental crises through sustainable science-based solutions. With environmental problems such as climate change, pollution, and ecosystem degradation on the rise, a comprehensive scientific approach is needed to identify effective mitigation and adaptation strategies. The research method used in this article is Systematic Literature Review (SLR). This approach is used to collect and analyze previous research that discusses the contribution of natural sciences in dealing with environmental crises. The literature analyzed includes international journals, academic books, and research reports from trusted institutions. The data are categorized based on relevance, methods, results, and conclusions of the research to gain a deep understanding of the latest developments in sustainable solutions. The results of the study show that natural sciences have a crucial role in overcoming the global environmental crisis through various innovations and science-based approaches. Continuous research has contributed to the development of solutions such as renewable energy, environmental conservation, and environmentally friendly technologies. To increase the effectiveness of the implementation of these solutions, closer collaboration between scientists, governments, industry, and the public is needed in integrating research results into real policies and practices. Thus, increasingly complex environmental challenges can be overcome more effectively, so that the future of the earth can be better preserved for future generations.
