Abstract

Desa Pondong memiliki peluang sebagai salah satu tujuan wisata di kawasan pesisir dimana didukung juga adanya Teluk Adang yang merupakan daerah Cagar Alam. Namun dalam perkembangannya kawasan mangrove terancam akibat adanya berbagai kebutuhan yang memaksa masyarakat untuk merusak mangrove, terjadi deforestasi, konversi lahan dan pembalakan liar. Mengetahui potensi ekonomi dan memberikan edukasi serta sosialisasi kepada warga masyarakat pesisir bagi kehidupan masyarakat menjadi bagian dari rumusan masalah yang akan dikaji. Desa Pondong menjadi lokasi penelitian dengan metode penelitian kualitatif dan menggunakan pendekatan studi masalah dengan kunci responden sejumlah tiga orang dan 30 narasumber kasus yang dipilih secara purposive sampling. .Hasil penelitian mengungkapkan bahwa Desa Pondong memiliki potensi yang sangat baik untuk dikembangkan & mampu menjadi obyek wisata unggulan. Potensi ekonomi Desa Pondong adalah sektor perkebunan, pertanian, perikanan dan obyek wisata. Konservasi ekosistem mangrove perlu dilaksanakan dengan cara melakukan kegiatan sosialisasi dan sosialisasi terhadap ekosistem ekosistem mangrove agar kelestarian lingkungan hidup terjaga.

Abstract

The objective of the present study was to examine the growth responses of Acacia mangium (mangium) and Paraserianthes falcataria (sengon) seedlings growing on different soil origin under nursery condition. This study was started in September 2012 and terminated in March 2013.  The seedlings were grown from seeds sown in a plastic box filled with sterilized sands. One week after sowing, the seedlings were transplanted into polybags contained sterilized soils originated from secondary forest, Imperata cylindrica grassland and ex-coal mining. The number of all seedlings were 180 seedlings consisted of 3 different soils, 2 species of seedlings with 10 seedlings replicated 3 times. Assessment was conducted one week after transplanting, then subsequently monitored every 2 weeks, except dry weighing and counting nodules were performed at the end of the study. A completely randomized design was used in this study. The data was analyzed using Costat software. The study resulted that the different of soil origin influenced on all growth variables of mangium and sengon of 4.5 months old. The survival rate of seedlings, height and diameter increments, dry weight and root nodules were better in both species of seedlings growing on soil originated from secondary forest and Imperata grassland compared with the soil from ex-coal mining. But the survival rates of sengon seedlings were higher than that of mangium on these three soils. The highest dry weight of sengon seedlings was achieved on soil originated from secondary forest. In the present study, soil originated from secondary forest increased more in weight of shoot than root, so that the shoot-root ratio was unbalanced more than one. Based on the results of this study, it is recommended that soil from secondary forest and Imperata grassland can be used as growing media for mangium and sengon seedlings in the nursery.

Abstract

Along with the increasing population growth, the demand for water and land needs also increases. So it tends to cause changes in land use, especially forests, which will affect the water system function of a watershed. This shows that there is a need for conservation efforts to maintain the sustainability of the watershed and its water availability. Land use is a reflection of human activities on land. Land use can be detected based on the land cover. Flood disasters occur due to land use that is not suitable for its designation. Changes in land use result in changes in surface water runoff which can be known based on the coefficient of surface runoff. The greater the rain that occurs, the greater the surface flow, resulting in floods and landslides. The Uwemanje sub-watershed is a hydrological regulator as well as a source of irrigation water for the villages of Porame, Binanngga, Baliase, Boya Baliase, Padende, Sibedi and Uwemanje Alone. The Uwemanje sub-watershed has a very important role in life, especially the daily needs of the Uwemanje community as well as agriculture, animal husbandry and plantations. To find out whether the hydrological characteristics of the Uwemanje sub-watershed are getting better or worse, the flow trend of the Uwemanje sub-watershed can be seen by calculating the runoff coefficient (C), by first analyzing the discharge and rainfall. This research was conducted from April to June 2022 in Uwemanje Village, Kinovaro District, Sigi Regency, and Central Sulawesi Province. The method used to determine the value of the runoff coefficient (C) is the rational method. Based on the observations and measurements made in this study, the results showed that the area of the Uwemanje Village watershed was 12,470,000 m², daily discharge was 12,966.57 m³, rainfall was 0.07893 meters, and the runoff coefficient (C) was 0.0013. The hydrology of the water catchment area (DTA) of the Uwemanje Village is still in a stable condition, which means that the forest with its function as a water regulator has not experienced high physical disturbances.
