Abstract

Indonesia is known to the world as a mega biodiversity country because it has vibrantbiodiversity. Semarang has a unique topography starting from the beaches in thecoastal areas, lowlands to hills in the southern region. The different landscapes affectthe biodiversity in Semarang City. This study aims to analyze the distribution of vegetation and create a vegetation profile of Semarang. The results showed that each species' dominant pattern in each growth rate was relatively spread. The ability to controleach species in the community was relatively balanced. The sustainability of speciesdiversity could be maintained. Besides, it is necessary to manage and preserve vegetation types that are quite dominant and have beneficial values in terms of economy,ecology, and even socio-culture in Semarang. They can become a characteristic ofSemarang as the capital of Central Java.

Abstract

Ketersediaan air merupakan bagian penting dari kehidupan masyarakat, karena hal tersebut akan sangat berpengaruh terhadap dinamika ekonomi pada sektor pertanian, perikanan, industri, perdagangan, transportasi, energi, pariwisata, dan lain sebagainya. Keberadaan mata di Kota belum teridentifikasi secara menyeluruh, sehingga belum dapat termanfaatkan dan terawat dengan baik. Oleh karena itu perlu dilakukan pemetaan mata air yang ada beserta potensinya, sehingga dapat dilakukan konservasi untuk menjaga keberlajutannya. Tujuan Penelitian ialah mengidentifikasi dan memetakan potensi serta ancaman mata air di Kota Semarang. Ruang lingkup Kajian Potensi Mata Air ini meliputi seluruh wilayah Kota Semarang yang terfokus pada Kecamatan Gunungpati, Mijen, Banyumanik, dan Candisari. Penelitian dilaksanakan dengan menggunakan pendekatan deskriprif kuantitatif, di mana pendekatan deskriptif digunakan untuk mengidentifikasi kondisi dan pemanfaatan sumber mata air di lokasi penelitian. Metode analisis data dalam penelitian ini menggunakan analisis spasial, hidrologis,. Hasil penelitian berhasil mengidentifikasi adanya 139 mata air, yang secara umum memiliki kualitas baik, meskipun debitnya relatif rendah. Pemanfaatan sebagian mata air tersebut yang digunakan sebagai sumber air minum dan mencukupi kebutuhan air domestik. Selanjutnya pemanfaatan mata air juga digunakan untuk mendukung kegiatan pertanian. Ancaman mata air di Kota Semarang, perubahan penggunaan lahan, hilangnya vegetasi pelindung dan resapan, pencemaran lingkungan, pembuatan sumur bor di sekitar mata air, erosi dan longsor karena tanah tidak stabil yang mengakibatkan mata air tertutup tanah.

Abstract

The Family of Hope Program (PKH) is one of the poverty alleviation programs organized by the Indonesian Ministry of Social Affairs. This conditional social assistance program aims to reduce the burden of spending and increase the income of poor and vulnerable families.  Currently the number of PKH Beneficiary Families (KPM) reaches 25,593 households. In order to make improvements to the PKH program, it is necessary to evaluate the sustainability of the program's usefulness in the future. Therefore this research was conducted to evaluate the feasibility of beneficiary families of government assistance programs (KPM PKH) in Semarang City. Besides aiming to evaluate the suitability of the community / family of beneficiaries (KPM PKH) in Semarang City based on criteria set by the Government, this study also aims to analyze the distribution of the use / utilization of government assistance by KPM PKH in Semarang City. Feasibility Study of Beneficiary Family Benefit Program (KPM PKH) Against Government Assistance Program in Semarang City is carried out using a concurrent mixed strategy. In this strategy the researcher took qualitative and quantitative data at once in a certain time span. The results showed that the district with the highest number of recipients was Semarang Utara District. Meanwhile, Tugu District is the region with the lowest number of beneficiary families. The gradual selection and verification process makes PKH acceptance in Semarang City selectively and on target (fulfilling eligibility criteria).

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 a fairly complete biodiversity ranging from genetic, species, and ecosystem levels. In addition, some of the plants identified are related to the historical value and local wisdom of Semarang City. However, the existence of some of these plants is currently threatened by the massive development of Semarang City and the reduction of green spaces. One of the solutions to conserve plants and maintain green spaces in Semarang City is through the development of Tinjomoyo Botanical Garden. The purpose of the study is to develop a design for the development of Tinjomoyo Botanical Garden in accordance with the ecoregion of Semarang City which is included in the East Java Rainforest with the concept of techno park. The design of the Tinjomoyo Botanical Garden is done through zoning arrangements that refer to the Semarang City Ecoregion which is included in the East Java Rainforest. The study results show zone IV with an area of about 10.04 hectares which is the zone with the highest level of suitability for the development of Tinjomoyo Botanical Garden. The arrangement of the botanical garden area, including the reception zone, management zone, collection zone, and recreation zone. In the collection zone 135 plant species as the initial collection of Tinjomoyo Botanical Garden, with a total of 1,834 individuals or collections divided into 8 categories, including historical plants, fruit plants, rare plants, endemic plants, aromatic plants, medicinal plants, forest zones and ornamental plants. Tinjomoyo Botanical Garden is planned to be built within the next 5 years in stages according to the urgency of development in each zone. Suggestions given in the development of Tinjomoyo Botanical Garden needs involvement, coordination, and cooperation with various sectors in order to develop and continue.
