Abstract

Sub-DAS Bila diindikasikan akan mengalami konversi lahan hutan menjadi ladang berpindah seiring perkembangan kebutuhan lahan saat ini. Tujuan penelitian ini untuk melihat pola perubahan penggunaan lahan dari tahun 2006 sampai dengan 2016 serta prediksinya tahun 2036 melalui penerapan model CA-Markov yang terdapat pada perangkat lunak Idrisi. Pola perubahan penggunaan lahan tahun 1996-2016 di sub-DAS Bila menunjukkan penurunan luasan signifikan pada penggunaan lahan hutan lahan kering primer sebesar 10,94% dan semak belukar sebesar 24,12%. Sementara luasan pertanian lahan kering campur semak meningkat signifikan sebesar 24,33% dan hutan lahan kering sekunder sebesar 10,64%. Begitu pula hasil simulasi prediksi penggunaan lahan tahun 2036, hutan lahan kering primer diprediksi berkurang seluas 10,2%, semak belukar diprediksi berkurang 7,15%, sedangkan hutan lahan kering sekunder diprediksi bertambah 8,63%, permukiman diprediksi bertambah 4,62%, pertanian lahan kering campur semak diprediksi bertambah 5,64%. Penerapan model CA-Markov untuk memprediksi penggunaan lahan menunjukan nilai  Kstandard 0,9 dinyatakan bahwa pemodelan diterima secara ilmiah.

Abstract

The conversion of agricultural land at a high enough rate may threaten the food security of the population. The agricultural land most vulnerable to conversion is the rice field. The aim of this study was to determine the changes in paddy fields from 2013 to 2020, the distribution of the transformation of paddy fields to other lands, and the factors that influence the conversion of paddy fields. This research was carried out by digitizing the on-screen image method in 2013 and 2020. The classification of land use results from digitization was tested for accuracy by determining the sample points in the GIS (Geographic Information System) application and then compared to the results of the field survey. In addition, an analysis of the changes in paddy fields was carried out by overlaying land use maps in 2013 and 2020. Observations and interviews with people whose land was changing were conducted on the factors affecting the change in paddy fields. Changes in land use over a period of 7 years (2013-2020), namely rice fields, decreased by 149 ha (7.36 percent ). Meanwhile, there has been an increase in the area in other land uses. The function of the paddy fields in the urban area of Pangkajene, Sidrap Regency, has become 18.69 hectares of land built, 59.42 hectares of mixed gardens, 23.13 hectares of open/empty land and 49.11 hectares of land. The factor that affects the conversion of paddy fields in the urban area of Pangkajene is the strategic location of the land, which causes the community to convert its land into a place of trade and services. The increase in the number of people requiring large land areas has led to the construction of many residential complexes in rice fields and the high selling price of rice fields, which encourages farmers to sell their land.

Abstract

Ambon City is the center of national activities in Maluku province, established under Presidential Decree 77 issued in 2014 about spatial planning of Maluku Islands. Ambon is a strategic region in terms of development in agriculture and fisheries sectors. Development of the region caused this area to be extremely vulnerable to the issues on water security. Seven watersheds which are Air Manis, Hutumury, Passo, Tulehu, Wae Batu Merah, Wae Lela and Wae Sikula affect the water system in Ambon City. Therefore, this study was conducted to determine the impact of climate and land use change on water availability in seven watersheds in Ambon City. The analysis was performed using a Soil and Water Assessment Tool (SWAT) Model in order to analyze climate changes on the period of 1987-1996 (past), of 2004-2013 (present) and climate projection on the period 2035s (future) and equally to analyze land use data in 1996 and 2014. The results of the research indicated that land use in the study area has changed since 1996 to 2014. Forest area decreased around 32.45%, while residential areas and agriculture land increased 56.01% and 19.80%, respectively. The results of SWAT model presented the water availability amount to 1,127,011,350 m3/year on the period of 1987-1996. During the period of 2004-2013, it has been reduced to 1,076,548,720 m3/year (around 4.48% decrease). The results of the prediction of future water availability in the period of 2035s estimated a decrease of water availability around 4.69% (1,026,086,090 m3/year). Land use and climate change have greatly contributed to the water availability in seven watersheds of Ambon City. Ambon City is in need of land use planning especially the application of spatial plan. The maintenance of forest area is indispensable. In built-up areas, it is essential to implement green space and water harvesting in order to secure water availability in the future.

Abstract

Ekowisata merupakan suatu bentuk perjalanan wisata ke areal alami yang dilakukan dengan tujuan mengkonservasi lingkungan dan melestarikan kehidupan serta kesejahteraan penduduk setempat.  Penelitian ini bertujuan:  (1) mengidentifikasi potensi wisata yang ada pada Dusun Rammang-Rammang(2) menyusun strategi pengembangan ekowisata karst di Dusun Rammang-Rammang.Pendekatan penelitian ini kualitatif dengan teknik analisis data yang digunakan deskriptif kualitatif dan SWOT. Pengumpulan data melalui observasi lapangan,wawancara dan studi literatur.Hasil penelitian menunjukkan bahwa keragaman obyek wisata yang terdapat pada Dusun Rammang-Rammang sangat beragam, dimana dapat diketahui dengan teridentifikasinya potensi-potensi wisata yang terdapat pada kawasan tersebut, baik secara fisik, biologi maupun sosial budaya. Faktor pendukung yang terdiri dari kekuatan dan peluang, yaitu: merupakan tujuan wisata yang jarang ditemui karena keindahan karst yang eksotis, memiliki obyek wisata yang beragam,meningkatkan potensi sosial yang ada serta sumberdaya alam dapat terjaga dengan baik. Sedangkan faktor penghambat terdiri dari kelemahan dan ancaman, yaitu; obyek dan daya tarik wisata belum tertata dengan baik, pengelolaan obyek wisata yang kurang professional, kurangnya fasilitas pendukung, dan terbatasnya sumber dana bantuan dari pemerintah. Hasil perhitungan matrik IFAS dan EFAS menghasilkan nilai sumbu X sebesar 1.2 dan sumbu Y sebesar 0.8. Hal ini menunjukkan posisi strategis berada pada kuadran I, dengan rumusan strategi S-O, yaitu; mempertahankan keindahan serta keunikan sumberdaya alam agar tetap terjaga,melibatkan masyarakat luar dalam pengelolaan ekowisata, pembentukan lembaga potensi ekowisata dan menambah keragaman atraksi budayayang dikemas dalam satu paket wisata.

Abstract

Changes in the area of mangroves in the coastal area of Maros Regency have been degraded from year to year. Various problems that often occur cause a decrease in the distribution and quality of mangrove community health. This happens because there is still pollution and external disturbances which make the quality of the mangroves decrease. Therefore, it is important to know the condition of mangrove distribution to find the latest information and baseline data for area managers. The purpose of this study was to obtain information on the extent and type of mangrove health, as well as identify the types of mangrove damage in the coastal area of Maros Regency in 2021. This research method used (1) supervised classification, to obtain mangrove distribution, (2) analysis of mangrove health using the normalized difference algorithm vegetation Index, (3) map overlay, mangrove distribution map, administrative map, and mangrove health index map, (4) validation of mangrove health data through an assessment of mangrove conditions based on the distribution of observational plots in a proportionate stratified with random sampling. Mangrove areas are found in the coastal areas of Maros Regency and are scattered in Marusu District, Maros Baru District, Lau District, Bontoa District with an area of 131.87 ha, 95.59 ha, 85.37 ha, and 60.01 ha, respectively. Mangrove health is divided into 5 categories, namely excellent, good, normal, bad, and awful with an area of 100.73 ha, 240.43 ha, 1.99 ha, 9.5 ha, and 20.2 ha, respectively. While mangrove damage based on 30 sample points, 6 types of damage were identified, namely changed leaves, damaged shoot leaves and shoots, broken/dead branches, open wounds, resinosis, and broken stems with percentages of 29.91%, 19.63%, 17.76%, 16.82%, 12.15%, and 3.74% respectively.
