FACTORS CAUSING THE TRANSFER OF FOREST FUNCTION TO CORN FARMING LAND IN DOMPU REGENCY

Nature is a component that plays an important role in human life. This big role cannot be separated from the provision of ecosystem services to fulfill needs in order to support life. These ecosystem services will not run properly if there is environmental damage. This environmental damage begins with the conversion of forest functions into corn agricultural land, humans only think about how to fulfill their desires without thinking about the impact it will have on nature and other humans. The purpose of this research is to find out the impact of land conversion which will change the function of the forest which should be the heart of earth's life into a corn farming field which will only benefit the parties concerned. Methods of collecting data using the interview method, direct observation of the field by looking at the existing conditions directly in the field. The results of this research show that there is a change in the function of forest land into corn agricultural land and changes the function of the area. Factors causing the conversion of forest functions are displacement, land use, economy and weak legislation. Key words : Environment, forest conversion, agriculture

Invasive Wild Pigs: A Significant Disturbance in Coastal Forests

Introduced in ~59 countries and native across Europe and Asia, wild pigs, Sus scrofa, are the most wide-spread swine species in the world. As ecosystem engineers, wild pigs are a significant source of disturbance in introduced ecosystems due to their numerous, complex impacts on ecosystem processes. Wild pigs are often found in the resource-rich habitat of coastal forests. Coastal forests are complex, dynamic systems with tremendous biodiversity. Exposed to recurrent disturbances, the biophysical characteristics of coastal forests contribute to their ability to return to their original state post-disturbance. However, compounding disturbances can weaken this ability and threaten the health and function of the ecosystem. In this review, through the model of the forests of the southeastern United States Coastal Plain, we (1) describe conditions found across the forested coastal landscape, (2) describe wild pig disturbance, and (3) discuss how wild pig impacts can add to significant anthropogenic and climate-related disturbances threatening coastal forests. Through this review, we find that the impacts of wild pig disturbance on coastal forests often have similar effects as anthropogenic and climate change-related disturbances that may enhance these significant threats to coastal forest function and resiliency.

ANALISIS SPASIAL SEBARAN LAHAN KRITIS DI KPHP UNIT XII BATANGHARI PROVINSI JAMBI

Critical land occured as a result of land cover changes from vegetated into non vegetated land or the composition of the vegetation has changed. This study aimed to analyze the distribution of land critical at KPHP Unit XII Batanghari. Critical land analysis was based on the Perdirjen PDASHL Number P.3/PDASHL/SET/KUM.1/7/2018. Land is classified into 5 levels of criticality, namely: non-critical, critical potential, somewhat critical, critical and very critical. The parameters used in determining the level of criticality of the land are: land cover, erosion-prone class, slope class and the presence of land inside or outside the forest function. Spatial analysis used by Geographic Information System (GIS) and remote sensing technology. GIS is able to analyze and represent geographic phenomenon. Landsat 8 imagery was analyzed to obtain land cover clasification. The results of the analysis showed that critical land level of KPHP Unit XI Batanghari consisted of 3,609 ha (4.45%) that classified as very critical and 3,599 ha (4,43%) as critical land. Then, land with a somewhat critical level had the largest area, namely 26,024 ha or 32.07% of the total area of KPHP Unit XII Batanghari. The landcover was the main parameter to determine the level of criticality of the land. The openland cover type had the maximum score 60.

The analytical method used is non parametric statistical correlation Spearman Rank. The instrument used is a Likert scale. The results obtained indicate that the Social characteristics that have a real influence on people's perceptions are age. While the level of community behavior is not influenced by the observed characteristics of the respondents. Keywords : behavior; characteristics; perception, community forest.

Drought and its impact on the bio-production of forests

The precipitation deficit, heat waves and subsequent drought significantly affected the forests in the Czech Republic. Primarily, forests were affected by physiological insufficiency and later by biotic and abiotic factors. On the initiative of the Ministry of the Environment of the Czech Republic, a study of the condition and damage of forest functions in the model area was formulated. The study was aimed at the model locality of the Bohemian-Moravian Highlands, especially the forest management unit of the Da?ice municipality (South Bohemian Region). The study uses certified national methodologies for evaluating forest function damage (Vyskot et al. 2003; Vyskot et al. 2014). This paper specifies the state and damage of the bio-production function depending on the represented forest management groups, stand types of woody plants and age phases of stands, in terms of value (in %) and finance in Czech koruna (CZK, the currency of the Czech Republic). In particular, spruce stands and their dominant mixtures of non-matured and fully matured trees were affected by major damage of a destructive nature. Due to the changed ecosystem conditions, a modified concept of forest management was proposed.

Fungsi Hutan Menurut Persepsi Masyarakat di Desa Sekitar KPH Banyuwangi Selatan Perum Perhutani Divisi Regional Jawa Timur

The issue of water scarcity is problem rife in various areas, especially in East Java. The aim of this study is to examine the causes of water scarcityin the village around the area Perum Perhutani South Banyuwangi KPH, Regional Division of East Java. In this study a head of village was appointment as key informance in villages were sampled to be interviewed.There are 30 respondents which represent each villages. Data were obtained from the representative with questionnaries, then analyzed descriptively. Based on the public preception of water scarcity during the dry season in Karangdoro and Sumbermulyo village is a slight different. Most of the villagers in Karangdoro didn’t experience the presence of drought due to availability of DAM and water at the well to the needs of household, while Sumbermulyo villagers suffered of drought due to lack of DAM, and unavailable water wells in the dry seasons. The majority of villagers of Karangdoro and Sumbermulyo agreed that the forest serves as the optimal land cover for catchments water, the aesthetics of nature, and nature conservation.

Rethinking Northern Hardwood Forest Management Paradigms with Silvicultural Systems Research: Research–Management Partnerships Ensure Relevance and Application

Well-designed, robust partnerships are important for addressing forest resource problems that intersect diverse ownerships, management, and research expertise. Here, we describe a case study of a research–management partnership. First, we describe the rationale and design of a large-scale, long-term experiment focused on increasing the sustainability and resilience of managed northern hardwoods. With the experiment as context, we next discuss details of the partnership contributing to its success, as well as some challenges. The experiment is a Michigan-wide evaluation of silvicultural alternatives to the current paradigm of selection silviculture. Our goal is to identify combinations of silvicultural treatments that increase the diversity and density of sapling recruits over forested landscapes where deer-browsing pressure and other limiting factors are at play. Pretreatment data from our 140-site study bolstered justification for the research, with sapling and pole classes generally lacking adequate stocking and diversity of desirable species over large geographic extents. We anticipate that the wildlife and forestry research–management model used to develop this project will be useful for other rapidly developing challenges that cannot wait decades to be addressed without potentially catastrophic losses to forest function. Key beneficial elements of our partnership include: (1) sensitivity to information needs at all management levels (i.e., policy to practice), (2) capitalizing on differences in strengths and reward systems of managers and scientists, (3) structured, frequent scientist–manager meetings to maintain focus on research and management application outcomes, (4) long-term relations and support that build trust, and (5) explicit wildlife and forestry collaboration on problems requiring joint expertise. Challenges to our partnership generally revolved around communication, workload, and implementation issues, and were partially alleviated by planning.

IMPLEMENTASI ALGORITMA C4.5 UNTUK PENGOLAHAN DATA HUTAN LINDUNG (STUDI KASUS: DINAS KEHUTANAN SUMATERA UTARA)

Data Mining is an information discovery by extracting information patterns that contain trend searches in a very large amount of data and assist the process of storing data in making a decision in the future. In determining the pattern classification techniques are done collecting records (Training set).Forests are a very important role for national and state development. Because forests can provide maximum benefits. However, the current situation of Protected Forest has experienced a drastic reduction in area, for that reason utilizing Protected Forest data can produce information about Protected Forest that is a priority and which is not a priority to be reforested or handled first so that the forest function is correct in its use.C4.5 algorithm or commonly known as the decision tree method can provide rule data information to describe the processes associated with processing protected forest data. The characteristics of the classified data can be obtained clearly, both in the form of decision tree structures and in the form of rules. So that in the testing phase with Tanagra 1.4 software can assist in processing valid Protection Forest data.Keywords: Data Mining, Protection Forest, C4.5 Algorithm, Tanagra Version 1.4
