Abstract

This research aims to analyze the water quality of Pari Island for seaweed cultivation. The main challenge involves the decline in seaweed production and quality, especially after the 2013 reclamation project. This research uses quantitative methods with primary and secondary data collection, water quality analysis involving parameters such as depth, temperature, salinity, pH and brightness, evaluated through the IDW method and weighting. The research results reflect an increase in temperature and salinity, resulting in a decrease in the quality of seaweed cultivation land on Pari Island. Reclamation factors and industrial activities also influence this condition. The seaweed cultivation land suitability map shows a significant decline from 2017 to 2023. The conclusion from research on changes in Pari Island's water quality regarding the sustainability of seaweed cultivation no longer supports optimal seaweed cultivation. The research recommendations highlight the need for sustainable planning and mitigating industrial impacts to support the growth of the seaweed cultivation industry on Pari Island.

Abstract

Jakarta as the center of economic activity and a city with a large population. This city needs public transportation that can cover the entire area. In addition, public transportation also needs to be integrated to facilitate mobility from one mode of transportation to another. However, the ignorance of residents about the cost and integration of public transportation in Jakarta is a factor that makes them choose to use personal vehicles. To overcome this problem, researchers conducted research using Geographic Information Systems (GIS) using descriptive methods with buffering analysis techniques to determine the integrity between KRL stations and Transjakarta bus stops and also using measure tools to determine the distance between stations. This research is purposed to find out the amount of KRL tariff that has been set by the government and to see whether public transportation between KRL and Transjakarta has been integrated or not. The results showed that only 22 out of 44 KRL stations were integrated with Transjakarta BRT stops. In addition, by using GIS, researchers can find out the actual distance between two KRL stations. This low percentage of public transportation integration shows that the government needs to play a role in building integrated public transportation. Public transportation integration will be able to increase public transportation users in Jakarta.

Abstract

The growth of regional development activities in Indonesia has recently begun to grow very rapidly, especially in land use that has begun to be converted. Sukabumi city is one of the cities in Indonesia with continuous development. The NDBI method is a way to detect the index variable of built-up land. In 2018, it shows that the Sukabumi city area is dominated by non-built-up land, which is 3561.17 ha and the smallest is very dense settlements, which is 1.08 ha. In 2023, it is dominated by undeveloped land with an area of 3562.84 ha and the smallest area in very dense settlements with an area of about 0.3 ha only. undeveloped land has an additional land area of 0.02% or 1.67 ha. An increase also occurred in settlements with a sparse density of 1.12% or 28.43 ha. Settlements with a tight density have an inverse trend from the previous 2 classifications, decreasing by 44.78% or 29.34 ha. Then in settlements with very dense density, it has a downward trend of 57.06% or 0.78 ha. This is a fairly good trend, where there is an increase in undeveloped areas and a reduction in land with a tight and very tight density.

Abstract

The decline in environmental quality, which can lead to an increase in air temperature, is an adverse impact of the phenomenon of urbanization and industry. An area will be more comfortable to live in if it is more densely vegetated. The capital of East Java province is Surabaya, the second largest city in Indonesia. ECI was analyzed based on LST and NDVI algorithms. Observations of surface temperature and vegetation density in Surabaya City were conducted in 2013 and 2023 by utilizing Landsat-8 OLI satellite images. NDVI classification levels are divided into 4, namely non-vegetation, low vegetation, medium vegetation, and high vegetation. Low vegetation is the most dominating NDVI level in 2013 and 2023 with 80.6% and 84.9% respectively. Surface Temperature Level in Surabaya City has increased in both maximum and minimum temperatures over the last 11 years. It can be seen that the temperature distribution with a level of >36 degrees Celsius in 2023 experienced a very significant increase, reaching 75.6%. The Environmental Critical Index in Surabaya City has four classifications, namely non-critical, low, medium, high. Each level of environmental criticality in Surabaya City was analyzed based on LST and NDVI within 11 years, namely 2013 and 2023. The level of environmental criticality in Surabaya City has generally decreased due to the increase in vegetation area, although the level of decrease has not been significant.

Abstract

Water scarcity is a serious environmental issue impacting many countries worldwide. Cloud seeding is a technology aimed at increasing rainfall by adding certain chemicals to clouds. Cloud seeding can enhance rainfall by up to 10%, which can support the water needs of additional households annually. The purpose of this literature review is to identify the most effective cloud seeding methods. The search was conducted using the SCOPUS database. The articles found were then selected based on their titles, keywords, and abstracts to ensure relevance to the research topic, resulting in 7 relevant articles. The literature review revealed various cloud seeding methods, such as Weather Research and Forecasting (WRF) cloud seeding, hygroscopic cloud seeding, and ECMWF cloud seeding. Based on an analysis of the advantages and disadvantages of these three cloud seeding methods, the most effective method is WRF cloud seeding because it is highly flexible and can be adapted to various weather conditions and topographies.

Abstract

Banjir merupakan bencana alam sering melanda Indonesia, terutama di daerah perkotaan seperti Jakarta. Tingginya curah hujan akibat iklim tropis, ditambah dengan faktor-faktor lain seperti posisi permukiman yang dekat dengan sungai dan penggunaan air tanah yang berlebihan, menjadi penyebab utama banjir yang terjadi setiap tahun. Meskipun Pemerintah Provinsi DKI Jakarta telah melakukan berbagai upaya penanggulangan, seperti pembangunan kanal dan normalisasi sungai, masalah banjir belum sepenuhnya teratasi. Oleh karena itu, penelitian ini bertujuan memanfaatkan Sistem Informasi Geografis (SIG) berbasis web sebagai alat untuk menyediakan informasi mengenai daerah rawan banjir di Kelurahan Kelapa Gading Timur. SIG berbasis web ini diharapkan dapat membantu masyarakat dan pemerintah dalam mengambil tindakan cepat dan tepat saat menghadapi bencana banjir. Dengan adanya media informasi kerawanan bencana banjir ini, diharapkan penanggulangan banjir di Kelurahan Kelapa Gading Timur dapat lebih efektif dan efisien.
