Abstract

What is the exact area of community forestry (HKm) land that can be effectively managed by farmers? The objectives of the study were 1) to identify HKm land management practices by farmers based on vegetation density and income at various strata of land area, 2) to analyze the effectiveness of HKm land management in various strata of land area, 3) to analyze the factors that influence the effectiveness of land management in various strata. strata of land area The method used in this research is descriptive through a series of observations, interviews and Focus Group Discussions. The number of respondents interviewed was 42 people. The variables studied included environmental aspects such as plant density, economic aspects in the form of production values and effectiveness assessment using scoring techniques, with the decision criteria being very effective, effective, quite effective, less effective and ineffective. Based on the results of the study, it can be concluded that (1) plant density in various land strata in strata I (<0.25 ha), strata II (0.25-0.5), strata III (>0.5-1ha) and Strata III (>0.5-1ha). IV(> 1 ha) were 382, 387,389 and 378 plants/ha, respectively. Meanwhile, the income of each farmer is (Rp/ha/year): 46,494,744; 25,479,880; 39,704,174 and 31,358,023. From various land strata, the level of effectiveness of the management is categorized as effective for land strata I, III, and IV and quite effective for land strata II. The factor that influences the effectiveness of land management is land area, where there is a tendency that the smaller the land area, the more effective the management. Other factors are the application of agroforestry patterns, other land tenure, availability of labor and age of farmers. Suggestions put forward for land distribution policies should consider the area between 0.5 - 1 ha, because it has provided sufficient income for farmers.

Abstract

Perforation irrigation is a unidirectional beam irrigation system that can be used for crop irrigation on dry land, due to the efficient use of water and the ability to wet land with a limited area. Therefore, the perforation irrigation system needs to be studied further in relation to the area of land that can be irrigated and the distribution of discharge to each perforated pipe. By testing several variations of the water level, the perforation irrigation emission capability will be obtained in the form of irrigation distribution, uniformity, emission capability and discharge amount used in irrigation on flat land. This study aims to determine the perforation irrigation capacity on flat land, the distribution of irrigation and the amount of discharge required. The test was carried out on three perforated pipes made of ½” PVC as lateral pipes, three transmission pipe length variations, such as 0.8m, 1m, and 1.2m with a distance between the perforations of 60 cm. The source of irrigation water comes from a 3 m tall tower with a capacity of ± 200 ????????????????????. The test uses three variations of head height, namely h1 350 cm, h2 360 cm, h3 370 cm and h4 380 cm. The results showed that the perforation irrigation jet length was around 100cm -120 cm, the uniformity of CU irrigation was above 97% with a total discharge on h1 QT = 0.689 lt/s, h2 QT = 0.690 lt/s , h3 QT = 0.695 lt/s and on h4 QT = 0.701 lt/s. While the range of flow rates for perforation 1 pipe Q1 (0.42 lt/s – 0.429 lt/s), perforation 2, Q2 (0.13 -0.145 lt/s) and perforation 3, Q3 (0.129 - 0.135 lt/s)

Abstract

Bungin Island is a very small island where population density is high, with a total population of 3,287 in a 2 kilometer-square area. The Annual Parasite Index (API) on Bungin Island in 2006 was 16,0 per thousand people. Outbreaks of malaria in Bungin Island are correlated with several controllable factors. The goal of this study is to aggressively detect and treat malaria, as well as to identify the factors that contribute to malaria outbreaks. Data was collected from the resident of Bungin Island who came to Sub-Primary Health Center Bungin Island in October 1, 2007. The data collection when outbreak malaria occurs, consisted of anamnesis, physical examination and test for type of malaria. A finger prick blood sample was collected and tested with rapid diagnostic test (RDT) for type of plasmodium. Treatment base on standard treatment for malaria from Indonesian Health Department was given to the subjects were malaria positive. The total 201 subjects was tested by RDT, in which 93 positive malaria (46,27%). Most of them were infected by Plasmodium vivax (97.85%) and only 2 subjects were infected by Plasmodium falciparum (2.15%). There were 23 subjects (24.27%) showed malaria positive without clinical symptoms. The subjects positive malaria with clinical symptoms, 8.57% were found to have spleenomegaly and 7.14% were found to have hepatomegaly. Incidence of malaria decrease siginifantly in few week after aggresive detection and appropriate treatment. A few years later, malaria incidence was disappeared. The incidence of malaria in Bungin Island was high when an outbreak occured. Aggressive detection with mass blood survey could find asymptomatic malaria in the population and appropriate treatment would decrease positive malaria until it disappeared.

Abstract

Traumatic brain injury is a condition of the head structure that is impacted or traumatized, causing disruption of brain function. This condition is one of the types of injuries that have the most severe effects on disability and death. Globally, 60 million people suffer from traumatic brain injury each year, with the most common complication being intracranial hemorrhage which increases the risk of death and disability. The incidence of traumatic brain injury is most common in the age group of children (0 - 4 years), adolescents and young adults (15-24 years) and the elderly (> 65 years). Where the most common causes are falls and vehicle accidents. This study aims to determine the histopathological description of edema in rat brain cells after traumatic brain injury and to analyze the relationship between differences in trauma burden and histopathological features of brain cell edema in rats after traumatic brain injury. This research is an experimental conducted by giving treatment to the object under study and then observing it. Sampling in this research will use purposive sampling. Where the researcher has determined the criteria of the sample to be used in the study so that it can represent the population. Based on the research conducted, it was found that there was a relationship between differences in trauma load and the percentage of brain cell edema in rats after experiencing traumatic brain injury. Where the greater the load given, the wider the surface of the brain that is experiencing edema. The results showed a significant edema appearance compared to the histopathological appearance of rat brain cells in normal samples. In addition, it was found that there was an increase in the percentage of areas with edema with a greater trauma load p=0.8156.

Abstract

Brain injury is a damage to the brain, not congenital or degenerative, but caused by an attack or physical impact from the outside. Traumatic brain injury (TBI) is an injury that occurs when a force transmitted to the head or body causes neuropathological damage and dysfunction. TBI is one of the most common head injuries worldwide. This disorder affects 2% of the world's population each year and is the leading cause of death and serious disability in children and young adults. Getting hit or bumped into objects, motor vehicle crashes and falls, and intentional self-injury are the most common causes of TBI. This study aims to determine the histopathological description of brain inflammation in post-traumatic brain injury rats and analyze the relationship between differences in trauma burden and histopathological features of brain inflammation in post-traumatic brain injury rats. This research is an experimental study conducted by giving treatment to the object under study and then observing it. Sampling in this research will use purposive sampling. Where the researcher has determined the criteria of the sample to be used in the study so that it can represent the population. The results of this study indicate that there is a relationship between differences in trauma load and the percentage of rat brain inflammation after experiencing traumatic brain injury. The results of data analysis from this study for the Pearson test obtained a significance value of 0.00 so that there is a correlation between differences in trauma load and the percentage of brain cell inflammation in rats after experiencing traumatic brain injury. The Pearson correlation value of this data is 0.7621 which means a strong correlation. The results showed a significant inflammatory picture compared to the histopathological appearance of rat brain cells in normal samples.

Abstract

Vitamin D has been associated with regulation on bone metabolism.  Recently, the extra skeletal effect of vitamin D has been researched. Increasing evidence demonstrated strong association between vitamin D and many biological process that regulate immune responses. Vitamin D deficiency is known to be related to the development of the autoimmune diseases. The discovery of the vitamin d receptor in multiple immune cell lineage supports vitamin D with a novel role in modulating immune function and its subsequent role in the development or prevention of autoimmune disease. Vitamin d Deficiency is related to development and severity of reumathoid arthritis (RA), Systemic Lupus Erythematosus (SLE), multiple sclerosis, Type 1 diabetes mellitus and inflammatory bowel disease. Normal level of vitamin D is required for immune function focus on therapeutic and prevention effect in autoimmune disease.

Abstract

The Peo Waume forest is a mangrove area located north of Kapota Island, Wakatobi Regency, Southeast Sulawesi. Visually, this area has the potential to be used by the community as an ecotourism object. Until now, this forest area has not been utilized optimally, although indirectly the ecological function of this forest supports various lives. Utilization of forest areas as ecotourism objects is estimated to be able to contribute to the socio-economic community, especially in Wakatobi Regency which is included in the National Tourism Strategic Area. This study aims to analyze the suitability of the Peo Waume Forest Area to be used as an eco-tourism area and to analyze its sustainability index by taking into account the ecological, socio-economic, and institutional dimensions. The results showed that the Peo Waume Forest Area was suitable to be used as a mangrove ecotourism object with an ecotourism suitability index of 2.15. The parameters used are mangrove thickness, mangrove density, mangrove type, tidal height, and diversity of biota objects. On the other hand, the sustainability index on the ecological dimension is 64.02, the socio-economic and culture dimension is 54.82and the institutional dimension is 50.94, indicating that the Peo Waume Forest sustainability index is insufficient. The lever factors that greatly influence the sustainability of the Peo Waume Forest Area are the attributes of community income, community waste management, and law enforcement.
