Abstract

Kabupaten Banjarnegara khususnya DAS Merawu memiliki kerawanan longsor yang tinggi. Perulangan longsor menyebabkan gangguan bagi kehidupan dan penghidupan masyarakat. Penelitian ini bertujuan menentukan zonasi kerawanan longsor dan menentukan strategi mitigasi longsor di DAS Merawu. Inventori longsor dilakukan menggunakan tiga pendekatan yaitu terestris, menggunakan citra satelit, dan dari literatur. Penelitian ini menggunakan analitic hierarchy process (AHP) untuk menentukan besar pengaruh setiap parameter lingkungan terhadap kejadian longsor sebagai dasar penyusunan peta kerawanan longsor. Metode AHP juga digunakan untuk menentukan jenis mitigasi longsor terbaik. Penelitian ini menunjukkan bahwa pada wilayah kajian terdapat 256 longsor, mayoritas berupa longsor tipe slide, dengan material utama tanah, dan termasuk deep slide. Longsor banyak terjadi pada wilayah dengan tanah mediteran merah tua dan regosol, formasi geologi Halang (Tmph), stream density 1,4-2,8 km/km2, lereng 25-45%, dan tutupan lahan semak belukar. Wilayah dengan kerawanan tertinggi terletak pada bagian tengah DAS. Jenis mitigasi longsor terbaik untuk wilayah ini yaitu penanaman vegetasi.

Abstract

Community forestry in Babak watershed is one of the efforts to reduce critical land area. The aim of this research was to evaluate the level of community forestry sustainability in both of community forest (HKm) and private forest in Babak watershed. Multidimensional scaling (MDS) was used to analyse the level of community forest sustainability based on the five dimensions of ecology, economy, social, institutional, and technology as well as 29 attributes. Leverage analysis was used to know the sensitive attributes of sustainability, while Monte Carlo analysis and goodness of fit was used to find the accuracy of MDS analysis. The result shows that HKm was in moderate sustainability level (sustainability index 54.08%) and private forest was in less sustainability level (sustainability index 48.53%). Furthermore, the ecology and technology in HKm were classified as less sustainable, while the institution and technology in private forest were considered less sustainable. There were 11 sensitive attributes of HKm and 19 sensitive attributes of private forest. The priorities of attribute improvement in HKm include land recovering (the dimension of ecology) and cooperative development (the dimension of technology). In private forest, the priorities of attribute improvement include leadership capacity building (the institutional dimension) and also the use of silviculture intensive and soil conservation (the dimension of technology).

Abstract

Kemuning sub village district is located in Bunder village, Patuk, Gunung Kidul. This area is near by the Bunder forest park and Wanagama Educational Forest. Most of the people live there are farmers. As the soil is relatively unfertile, they prefer to plant trees, so they called as forest community farmers. Among the trees, they plant cassava, peanut, and corn, so it called as agroforestry. In the field, the area seems still has the opportunity that can be added to be planted. Based on this situation, in this project, the optimalization of land use was introduced to ask the farmers to plant the undergrowth species includes: zingiber, kunyit and kencur. This project was started by introducing the agroforestry system, where they can plant together both trees and non trees at the same land. The socialization was done by inviting the farmers to come to the meeting. The advantages of agroforestry was explained to them, and also the post harvesting management to produce the instant zingiber was also trained and demonstrated to the female farmers. This product is also useful for attracting the local tourist who usually come at the week end. The output of this project was the agroforestry demplot can be built in the field, so the farmers can learn and study to develope at their own land. The female farmer can also make the instant zingiber as the healthy drink.

Abstract

Around 12.62% of watersheds in Indonesia are damaged and need restoration immediately to prevent floods, landslides, and other related disasters. This study aimed to evaluate the Wosi watershed and formulate conservation scenarios to improve its conditions. The data collection included hydrology (quantity, continuity, and water quality), land (critical land index, percentage of vegetation cover, and erosion index), socio-economic (population pressure, welfare level, existence, and regulations enforcement), building investment (city classification and water building value classification), and the use of space (protected areas and cultivation areas). The evaluation of carrying capacity used a scoring analysis. The scenarios formulation used the information on potential carrying capacity and conservation strategies. The results suggested that the carrying capacity of the Wosi watershed from 2016-2019 had fallen into "bad" and "very bad" categories. To improve these conditions, the government can assign the riparian areas as a government asset, build ponds and dikes in the flood-prone areas, apply small recharge pond (SRP) on the cacao plantations, and assign Wosi Rendani protected forest (HLWR) as an urban forest. The implementation of these conservation strategies will result in the improvement of (a) the carrying capacity of the Wosi watershed and (b) the status into the "good" category to support environmentally friendly development in Manokwari city.

Abstract

Impact of Tourism on Soil Erosion in Tourist Area of KaliurangTourism is one alternative of non timber based forest managements however, tourism activities will impact on the tourist areas, both biophysically and socially. The purpose of this research was to study the factors influencing soil erosion rate in tourist area, and to examine the effect of tourist characteristics, e.g. visiting characteristics and tourist activities on erosion rate.The erosion prediction was carried out at tourist areas including Hutan Alam (Natural Forest), Taman Bermain Anak (Play Ground), Taman Wisata Alam (Natural Tourist Park), and Kali Kuning Camping Ground. The Universal Soil Loss Equation (USLE) model was applied. Correlation analysis was used to analyze the correlation between factors influencing soil erosion rate (rainfall erosivity, soil erodibility, slopes, vegetation and conservation practices) and erosion.The research resulted that tourism significantly impacted on erosion at Play Ground, Natural Tourist Park 1, and Kali Kuning Camping Ground, except at Natural Tourist Park 2. The correlation analysis showed that all of the factors influencing soil erosion rate positively affected erosion. The results also showed that the tourist characteristics which influence erosion rate were tourists' visiting characteristics and their activities.

Abstract

Hutan Wanagama I Gunungkidul memiliki topografi yang berbukit-bukit dan berlereng sehingga berpotensi tinggi menimbulkan erosi. Kombinasi tebal hujan yang relatif tinggi dan keadaan topografi dengan kemiringan curam berperan penting untuk menghasilkan aliran permukaan yang dapat menimbulkan erosi. Tujuan penelitian ini adalah untuk menganalisis hubungan antara tebal hujan terhadap aliran permukaan, aliran permukaan terhadap erosi, dan tebal hujan terhadap erosi dengan menggunakan analisis regresi linear sederhana. Di Hutan Wanagama I banyak terdapat lahan rumput Kolonjono (Brachiaria mutica) yang ditanam oleh masyarakat sekitar. Oleh karena itu, sangat mendesak untuk dilakukan penelitian erosi pada lahan rumput Kolonjono tersebut untuk menghindari terjadinya degradasi lahan. Penelitian ini dilakukan dengan menggunakan metode plot kecil untuk menganalisis tingkat erosi dan aliran permukaan. Pada penggunaan lahan rumput dibuat 3 plot kecil berukuran 22 m x 4 m, yang dipasang terpisah searah lereng, masing-masing mewakili bagian atas, tengah, dan bawah lereng. Hasil penelitian menunjukkan bahwa erosi selama penelitian tergolong sangat rendah, pada plot atas sebesar 52,52 kg/ha, pada plot tengah sebesar 48,44 kg/ha, dan pada plot bawah sebesar 57,90 kg/ha. Tebal hujan sangat memengaruhi aliran permukaan dan aliran permukaan sangat memengaruhi erosi. Hasil penelitian juga menunjukkan bahwa aliran permukaan selama penelitian pada plot atas sebesar 18,26 mm dengan koefisien aliran permukaan sebesar 0,0482, pada plot tengah sebesar 16,92 mm dengan koefisien aliran permukaan sebesar 0,0447, dan pada plot bawah sebesar 20,03 mm dengan koefisien aliran permukaan sebesar 0,0529 yang kesemuanya tergolong baik.
