Abstract

The forest area of SMBU is the largest conservation forest area in Southeast Sulawesi, located in the Buton archipelago, has many potential of forests that have abundant diversity. However, in line with the development of population andregional development, there has been a disruption to the forest area in the form of illegal logging. This has an impact on the decreasing diversity of forest vegetation in the region. The aim of the study was to analyze species richness and abundance as an indicator of the ecological diversity of forests in the forest area of the SMBU. Plant species measurement data are used to calculate the frequency, density, dominance and importance value index of vegetation, while analyzing the ecological diversity of forest vegetation with the calculation model using the diversity index method, species richness index and similarity index. The results showed that some species had the highest density, frequency and dominance at the tree spesies, namely the Holea (Cleistanthus sp), Redwood (Shorea spp) and Guava (Syzygium spp). At the pole level there are types of Guava (Syzygium spp), and Wukumalampa (Polyalthia lateriflora). While at the saplings level, guava (Syzygium spp) is found. Diversity index values at tree level, pole and saplings can be categorized as having decreased compared to the results of previous studies. The abundance of species shows that there is a tendency for the lower vegetation structure at the level of the pole and saplings to be less abundant. Keywords: forest area, northern buton wildlife reserve, forest structure, ecological diversity, diversity index

Abstract

ABSTRAKAnalisis kuantitatif parameter morfometri DAS merupakan suatu hal yang penting digunakan dalam mengevaluasi DAS Konaweha, dalam menentukan prioritas untuk konservasi tanah dan air dan pengelolaan sumberdaya alam dalam skala mikro pada level Sub DAS. Sebab peningkatan pengelolaan sumberdaya  lahan, tanah dan air pada suatu DAS, memerlukan data tentang karakteristik morfometri yang mengindikasikan tentang degradasi dan erosi tanah. Tujuan penelitian ini adalah untuk: (i) menghitung dan menganalisis karakteristik morfometri DAS Konaweha dan Sub DASnya, (ii) menganalisis dan menentukan skala ranking atau prioritas pengelolaan DAS pada semua Sub DAS di  DAS Konaweha. Hasil penelitian ini menunjukkan bahwa DAS Konaweha dengan karakteristik morfometri terdiri dari parameter  areal, linear dan bentuk  seperti kerapatan sungai, tingkat percabangan sungai, frekuensi sungai, rasio bentuk DAS, faktor bentuk, rasio membundar dan rasio memanjang, dapat disimpulkan bahwa DAS Konaweha dan semua Sub DAS nya umumnya merupakan DAS yang memanjang yang menunjukkan debit puncak banjir yang tidak terlalu cepat dengan waktu penurunan yang tidak terlalu lambat, air mempunyai banyak waktu tersimpan/terinfiltrasi ke dalam tanah.  DAS Konaweha tidak rawan banjir, namun apabila jika terjadi kondisi iklim yang ekstrim mengalami banjir besar, maka penggenangan karena banjir tersebut akan terjadi dalam waktu yang relatif lama, sehingga DAS Konaweha sangat peka terhadap banjir puncak (peak of discharge). Berdasarkan analisis karakteristik morfometri beberapa Sub DAS menunjukkan sebagai  prioritas utama untuk dilakukan pengelolaan seperti Sub DAS Konaweha Lahumbuti, Sub DAS Tinobu, Sub DAS Kokapi, Sub DAS Lembo dan Sub DAS Aloalo. Kata kunci: Sub DAS, Analisis Multivariat,  Korelasi Parameter Morfometri, Prioritas Pengelolaan.  ABSTRACTThe analysis of quantity watershed morfometric is most interesting used to evaluated Konaweha Watersheed  and to determine management priority soil and water conservation, and natural resources at micro watherseed or Sub Watersheed. Because improving management of land resources, soil and water in watersheed need data about  morphometry characteristics who indicate land degradation and errosion. The aims of research is: (i) to compute and analysis morphometry characteristics Konaweha Watersheed and their sub watersheed, ( ii) to analysis  and  determine ranking scale or priority of watersheed management of all sub watersheed in Konaweha Watersheed. The results of research showed that Konaweha Watersheed have morphometry characteristics i.e. linear, areal and shape parameter as area of watersheed,  perimeter watersheed, length of watersheed, bifurcation ratio, drainage density, stream frequency, form factor ratio, shape factor, circulatory ratio and elongation ratio, can be concluded that Konaweha Watersheed and all of their sub watersheds have shape elongation to show that peak discharge  not quickly with time of recession is not slowly, the water many time to recharge as infiltration water in soil. Konaweha Watersheed is not prone to flooding, but if there is extreme climatic conditions then cause the Konaweha Watershed to flood large, resulting in waterlogging in a relatively long time, so Konaweha Watersheed is very sensitive to peak discharge.  According analysis morphometry characteristics some sub watersheed show that as the first priority to manage i.e. Konaweha-Lahumbuti Sub Watersheed, Tinobu Sub Watersheed, Kokapi Sub Watersheed, Lembo Sub Watersheed and Aloalo Sub Watersheed. Key Words: Sub Watersheed, Multivariat Analysis, Correlation Morphometri Parameter, Priority of Management

Abstract

The management of agricultural land that is still conventional and the lack of information related to land management has caused the condition of several agricultural lands in Lambakara Village to be quite concerning. The condition of Lambakara Village which is directly adjacent to the village with hilly topography and steep slopes can cause Lambakara Village to be prone to landslides and flooding. In addition, the quality and quantity of soil can decrease as a result of long-term agricultural management. One alternative to overcome the problems faced by Lambakara Village is the application of the Agroforestry system. the purpose of this service is to provide knowledge and learning to farmers as an effort to increase public knowledge about agroforestry applications. The initial stage was carried out in the form of a location survey stage to find out which community lands could be used and have the potential to implement the Agroforestry system. The socialization stage was in the form of interviews and coordination with village officials, related stakeholders, and the community in introducing the Agroforestry system as an effort to conserve agricultural land to support sustainable agriculture. The implementation stage is in the form of public education regarding the Agroforestry system and direct planting of forestry plants on community agricultural land. All stages of community service activities in Lambakara Village were carried out well. The involvement of village officials and the local community is the main indicator of achieving the target of this activity. As many as 300 nutmeg seedlings were successfully planted on the community's agricultural land
