Abstract

Pertumbuhan ekonomi yang tinggi di Jakarta diiringi dengan pertambahan jumlah penduduk dan pembangunan infrastruktur yang semakin padat. Tingginya tingkat pembangunan infrastruktur di Jakarta menyebabkan semakin berkurangnya tutupan vegetasi dan terganggunya fungsi alami ekosistem yang semula ada di Jakarta, seperti fungsi sistem hidrologi. Pembangunan fisik dan infrastruktur di daerah perkotaan seharusnya diimbangi dengan pengelolaan lingkungan yang seimbang sehingga dampak negatif yang timbul dapat diminimalkan. Salah satu bentuk pengelolaan lingkungan dapat dilakukan dengan pengaturan dan pemanfaatan ruang yang optimal sehingga fungsi ekosistem tetap terjaga. Studi ini bertujuan untuk menganalisis bagaimana hubungan perubahan tutupan lahan terhadap sistem hidrologi yang dilihat dari persediaan air dan fenomena banjir di Jakarta, serta menyiapkan rekomendasi untuk perencanaan ruang berbasis sistem hidrologi. Analisis dilakukan secara kuantitatif dengan bantuan Sistem Informasi Geografis, berdasarkan data sekunder dan studi literatur. Berdasarkan pengolahan citra Landsat tahun 1999-2019, terjadi perubahan tutupan lahan dimana tutupan lahan vegetasi di Jakarta mengalami penurunan dari 35,5% menjadi 6,4%, sementara luas lahan terbangun terus mengalami peningkatan dari 65,5% menjadi 93,6%. Kepadatan bangunan di Jakarta menyebabkan peningkatan luas permukaan tanah yang bersifat impervious sehingga terjadi peningkatan laju aliran air permukaan dan penurunan laju aliran dasar di bawah tanah sehingga memicu terjadinya banjir.

Abstract

Economic growth and increasing population density have an influence on the large need for electrical energy in Indonesia. The amount of energy needed is directly proportional to economic growth and population density. This condition could threaten energy security in Indonesia if all stakeholders still depend on non-renewable energy. Coal, oil, and natural gas, which are continuously exploited for generating electricity, will eventually run out and will no longer be able to meet Indonesia's electrical energy needs. Apart from that, the use of non-renewable energy also has a negative impact on the environment. Indonesia is a country that is rich in renewable energy sources that can be used as a source of energy for generating electricity, but there are still obstacles in processing and using them, so they are not optimal. This paper aims to analyze the potential and challenges of providing electrical energy in Indonesia. The method used is a descriptive method using primary and secondary data and literature studies. The results of this study show that the potential for renewable energy that can be processed and developed for electricity generation is quite large, namely from energy sources originating from geothermal, hydropower, mini-hydro and micro-hydro, bioenergy, solar power, wind energy, and ocean waves. The survey results show that 52% of the public agree with the use of renewable energy, and 43% agree with the use of nuclear energy as a source of renewable electrical energy. The reason for choosing nuclear energy is the reliability of the energy supply. A strategy for developing renewable electrical energy can be formulated based on the opportunities and challenges currently faced to achieve energy security in Indonesia. Efforts to develop renewable electrical energy need to be carried out with the cooperation of all relevant stakeholders so that the sustainability of electrical energy in Indonesia can be realized.
