Abstract

Semarang City has a low and flat topography in several areas so that it has a high risk of inundation during the rainy season with a spatial distribution in the city center area. In 2022 inundation floods have inundated 877.66 hectares, one of which is in the Tembalang area and its surroundings with a height of around 275 MDPL which occurred in 20 locations with an area of around 33.62 hectares, where the area is the downstream part of the Babon Watershed. The results of the analysis of rain in the Babon watershed area for 20 years show that it is relatively stable, not too much variation, where the results of calculating the rational flood discharge for 2022 with a return period of 2 years are around 25.80 m³/s. Furthermore, the morphometric analysis of the watershed shows that the shape of the Babon watershed is relatively elongated with a circularity ratio <0.50, the density index of the river is 0.25 – 10 km/km² which is in the medium density category with a relatively long Time Concentration (TC) of around 3.2 hours so that it is less thus impacting flooding downstream. The Babon watershed runoff coefficient is affected by land cover conditions, where the interpretation results show that there was a change in land cover from 2002 – 2022 for the area of built-up land which increased by 708.44 hectares and the vegetation area decreased by 486.77 hectares. Analysis of channel capacity shows that there is potential for overflow from existing channels in 7 sub-watersheds which will result in inundation. The conclusion of this study shows that rainfall over the past 20 years has been relatively stable and the morphometry of the watershed has not had much impact on downstream flooding, the main river capacity of the Babon DAS is still sufficient to accommodate the planned flood discharge with a return period of 25 years. So that inundation that occurs is more caused by changes in land cover and drainage capacity in the downstream.

Abstract

Gunungpati District has an ex-JSDF land area of 73.2 ha consisting of 67 parcels of land spread across 12 Sub-Districts. The ex-JSDF land area was originally a poverty alleviation program and critical land conservation in the City of Semarang in collaboration with the JSDF (Japanese Social Development Fund), Worldbank and the City Government of Semarang. The development of several ex-JSDF land locations has developed into agro-tourism areas such as those managed by the Agriculture Service in Cepoko Village. However, several other locations managed by farmer groups were abandoned and then experienced land conversion. So that the potential of the ex-JSDF in the region was identified to obtain a pilot strategy for sustainable tourism in the city of Semarang. The research was carried out by identifying tourist attractions and tourism development factors so that directions for developing integrated and sustainable tourism areas in Gunungpati District could be obtained. the results of the analysis of the suitability of cultivated land in the former JSDF land locations spread across 12 sub-districts, 11 of which have an S1 suitability class, namely its use is very suitable for cultivating fruit crops. Meanwhile, one other location, namely Sumurrejo Village, has a Masters degree of suitability (quite appropriate). In general, the limiting factors in the heavy research sites were soil texture and fertility which were in class S3. Another mild limiting factor is temperature and groundwater productivity which are in class S2. Sustainability analysis found that the level of sustainability of fruit cultivation on ex-JSDF land in the Gunungpati District area was in a less sustainable status, the resulting index value only reached 58.94. Integrated tourism development area in Kec. Gunungpati with the main tourism zones covering, 1) Agroeduwisata Kandri Tourism Village, 2) Kreo Cave & Jatibarang Reservoir, 3) Kandri Boat Tourism, 4) Ngrembel Asri, and 5) Firdaus Fatimah Zahra.

Abstract

Semarang City has the fastest development in Central Java Province, where the activities are no longer centralized but have expanded to the upper part of the region. The ongoing development certainly impacts changes with the increasing area of built-up land that converts to another cover, such as vegetation. The phenomenon impacts the balance of the environment, one of which is the source of springs. Therefore, this study aims to map the spatial distribution of the springs and identify their physical quality. A quantitative approach was used with spatial analysis. Meanwhile, data collection techniques used document research, high-resolution image interpretation and field surveys. Field surveys were conducted to test the accuracy of land use maps and measurements of discharge, temperature, pH and brightness of the springs. The results showed that there is a change in land use from 2016 - 2021 with an increase in settlements of around 77.25 hectares and commercial service buildings by 178.79 hectares. For land use with the largest decrease in area, agricultural land covers and mixed garden/vegetation covers an area of ​​207.01 and 50.57 hectares. There were 114 springs at the research site, of which 5% of the springs had a relatively large discharge above 10 liters/second, while the other 47% had a small discharge. For pH conditions, there were 6 springs with a pH value of less than 6. Land use change from vegetation to flying land impacts the reduction of the water supply in the soil. The impact can be seen by the non-production of several springs, where 21 springs have not been discharged. In conclusion, there is a change in land use with an increase in built-up from 2016 - 2021 by 256.04 hectares. The increase in built-up is partly in conservation areas, hence damaging several springs.

Abstract

Tambakrejo Village is one of the areas in Semarang City that is often affected by flooding, administratively it is included in Gayamsari District. Being in a coastal area with an elevation close to sea level means that the Tambakrejo District area has the risk of flooding and tidal problems, where tidal disasters have so far submerged more than 2.5 hectares of land with 25 residents' houses lost. Flood and tidal conditions directly or indirectly affect all aspects of people's lives. The impact of disasters results in damage to facilities and infrastructure, disruption of social activities, education and public health. If this continues, it is feared that it will increase community vulnerability and decline. The aim of the DPIK program is to increase community capacity to have the independent ability to adapt in facing potential disasters and other impacts of climate change, through the Smart and Disaster Resilient Village movement.

Abstract

Indonesia’s coastline, particularly Kendal Regency in Central Java, faces critical mangrove degradation due to land-use changes and rising sea levels. This study aims to asses the condition and erosion impacting Kendal's mangrove ecosystems to inform future conservation strategies. Using remote sensing technology, multi-spatial and multi-temporal imagery from 2005–2023 was analyzed and validated with field observations to evaluate mangrove species composition, structure, and land changes. The mangrove area increased by 52% in three locations, with the Bodri River delta (Pidodo Kulon and Pidodo Wetan villages) showing the most significant growth at 76.69 hectares. Ngebum Beach (Mororejo) had the largest proportional increase, reaching 185%. The ecosystems are moderately diverse, containing at least 11 mangrove species, though Rhizophora dominates due to extensive planting efforts. Despite stable conditions, these ecosystems face threats from deforestation for aquaculture, the primary driver of land erosion, compounded by rising sea levels. Although mangrove areas have expanded significantly, ongoing challenges include erosion, anthropogenic pressures, and limited species diversity. Future strategies must involve multi-stakeholder collaboration to implement sustainable practices, promote species diversity, develop erosion mitigation models, and conduct awareness campaigns to ensure the resilience of Kendal’s mangrove ecosystems.

Abstract

Intrusi air laut merupakan salah satu masalah utama yang umum terjadi di wilayah pesisir. Kecamatan Cilacap Tengah merupakan salah satu kecamatan di pesisir selatan Jawa yang diduga mengalami intrusi air laut yang juga memiliki ekosistem hutan mangrove. Hutan mangrove dianggap mampu meminimalisir terjadinya intrusi air laut melalui sistem perakaran, batang, dan daunnya yang mampu beradaptasi dengan air asin. Penelitian ini bertujuan untuk mengetahui pengaruh hutan mangrove terhadpa intrusi air laut yang dilakukan dengan menganalisis distribusi spasial dan ketebalan hutan mangrove terhadap intrusi air laut. Analisis yang digunakan yakni analisis spasial. Hasil penelitian menunjukkan bahwa hutan mangrove tersebar di Kelurahan Kutawaru, Donan, dan Lomanis. Adapun ketebalan hutannya berkisar 0-867,3 m. Hasil pemetaan intrusi air laut menunjukkan bahwa di Kecamatan Cilacap Tengah terdapat daerah yang tidak terintrusi, intrusi sedang, dan intrusi tinggi. Berdasarkan hasil pemetaan di antara keduanya, menunjukkan bahwa di daerah yang bermangrove luas dan tebal tidak mengalami intrusi hingga mengalami intrusi sedang. Sedangkan daerah yang tidak bermangrove dan bermangrove tipis mengalami intrusi sedang hingga tinggi. Sehingga penanaman hutan mangrove harus dilakukan secara lebih merata di lahan-lahan yang tidak bermangrove sama sekali, mengingat keberadaan hutan mangrove berpengaruh terhadap kondisi intrusi air laut di Kecamatan Cilacap Tengah.

Abstract

Industrial areas in Indonesia are increasing every year with a total of 136 industrial estates in 2024, of which 61.76% are in Java, such as Kendal Industrial Estate (KIE) with an increase in built-up land of 289.52 hectares (2015-2017). The problem is that the development was carried out by converting vegetation cover. The purpose of the study was to analyze the impact of the increase in built-up land on the environmental quality index around Kendal Industrial Estate. Research method with supervised classification Random Forest method and spectral transformation Risk Screening Enviromental Indicators with indicators of greenness index, humidity Index, dryness Index and heat index with Principal Component Analysis technique. The results showed that built-up land around KIE increased by 894.17 hectares which resulted in a decrease in vegetation cover of 184.71 hectares (2015-2024), this phenomenon had an impact on increasing low-level RSEI by around 2,028.31 hectares (2015-2024). The regression results show that the increase in built-up land and the reduction of vegetation cover have an impact on the decline in environmental quality in the study area. The contribution of the research results can be used as a database for regulation of land use change restrictions.
