Abstract

Sumatran orangutans (Pongo abelii) learned the process of building nests from their mothers and started building nests around the age of 0.5 years. Orangutan nests have the most intricate arrangement of other primate nests. Orangutans built the nest as a place to rest, play, and protect themselves from predators and insect bites such as mosquitoes. Orangutan nests have different locations tailored to the needs and context of the nest trees. The shape of the nest and the position of the nest usually have differences due to differences in sex, age level, and body weight. The research had conducted at the Jantho Orangutan Reintroduction (JOR) Station, Aceh Besar Regency, Aceh Province. It had carried out from January to August 2021. The research method used is purposive sampling. The selected transects are existing (permanent) with FB, RI, and IS coding, which is part of mammalian transects scattered in the Jantho Pine Forest Nature Reserve. Observations were carried out as many as two repetitions in different months. The results showed several classes and nest positions found at the JOR Station. The nest classes found were 1, 2, and 3, while the others were not found. Nests in position 2 were the most founded at the study site, and position 5 was not found. It indicates no orangutan at the study site liked to play on the ground. This study gets four nest shapes, namely single round, flat oval, tiered, and irregularly widened

Abstract

The Sibolangit Nature Tourism Park (SNTP) holds immense potential as a natural attraction, but effective management faces challenges due to limited resource utilization and community engagement. To address this, a comprehensive stakeholder analysis was conducted. The research was conducted within SNTP, Deli Serdang Regency, between May and June 2021, utilizing questionnaires and in-depth interviews to gather primary data from 25 key informants. Stakeholders represented central and local governments, surrounding communities, and non-governmental organizations (NGOs) such as the Sibolangit Tourism Awareness Group. The collected data underwent thorough analysis to assess stakeholder interest and influence levels. Stakeholders were categorized into key players, context setters, and the crowd. Key players included the North Sumatra Natural Resources Conservation Center, SNTP, and the Deli Serdang Culture and Tourism Office, exerting significant influence in policy formulation and resource allocation. Context setters, represented by local communities, held substantial influence and played crucial roles in decision-making and implementation. The crowd, comprising NGOs, demonstrated high interest but lower influence in management. Collaboration among stakeholders, particularly central and local entities, emerged as pivotal for effective SNTP management. Stakeholders' roles significantly impacted management outcomes. This study highlights the necessity of holistic collaboration and balanced resource utilization for sustainable nature tourism management within SNTP. The findings contribute to a comprehensive understanding of stakeholder dynamics and their roles in achieving the objectives of SNTP management

Abstract

Coffee production potential is matched by waste from grinding coffee cherries. However, the coffee cherry peel (husk) is rich in essential nutrients for plant growth, including potassium, phosphorus, and nitrogen. Therefore, the purpose of this research was conducted to determine the physical quality of coffee husk compost given the addition of EM4 bioactivator. This study consisted of 2 treatments and 4 replications, namely control (coffee husk + sawdust + goat manure) and EM4 (coffee husk + sawdust + goat manure + EM4). Observations were made every 3 days until the compost was ripe with the parameters of temperature, humidity, color, smell, and texture. The results showed that the entire coffee husk compost had matured within 36 days and exhibited physical characteristics according to SNI 19-7030-2004. According to the matured compost speed, treatment with mixing compost materials using EM4 shows a faster time than without EM4. In addition, the addition of EM4 gives better results in terms of texture, color, and smell compared to compost without EM4

Abstract

The contribution of forest in North Tapanuli Regency can increase the economic income of the local community through the use of Non-Wood Forest Products (NWFPs). Most village communities around the forests of North Tapanuli Regency have used NWFPs for generations to meet their needs. This study aims to analyze the value of the contribution of NWFPs to the income of village communities to determine the level of community dependence on these forest resources. Knowing the value of the contribution of NWFPs can be used as recommendations for policymakers to allocate increasingly scarce NWFPs and distribute the benefits of NWFPs fairly and optimally. This research was conducted in five Districts in North Tapanuli Regency considering that there are still many people who live depend on NWFPs. The research method was carried out by field observations and interviews using questionnaires, with a total sample of 98 respondents. Respondents were taken using the purposive sampling method. Respondent identification was done through the snowball technique. Data analysis of the contribution value was carried out by calculating the total income of the community, such as incomes sourced from NWFPs and other income. The results showed that the monthly income of villagers outside of NWFPs was in the range of IDR 1,000,000 – 2,000,000. Then the contribution of NWFPs to the income of villagers around the forest was 74.9% of income outside of NWFPs

Abstract

Papua is well-known for its medicinal plants. However, several of them are not well documented yet. Numerous efforts have recently been addressed to record medicinal plants in different parts of Papua. This study aimed to identify medicinal plants in the Inamberi Research Station of Manokwari, West Papua Province. All plant species grown in the research station were listed and documented. The method used in this study was the observation method with survey techniques. Literature reviews were performed to identify the medicinal plants that were generally used by the local people of Papua. The conservation status of medicinal plants was derived from the IUCN red list website. The total medicinal plants grown in the research station were about 43 species, dominated by Euphorbiaceae and Moraceae families. Trees were the dominant medicinal plants. Medicinal plants in the research station can treat various diseases and some of them can cure more than one disease. Local people of Papua generally utilize leaves as medicinal plants. The utilization of medicinal plants was simple: boiling and drinking, directly eating it, chewing and attaching it to the wounds, and rubbing it on the skin. The conservation status of medicinal plants was categorized as low risk. However, concern should be given to Pterocarpus indicus that has been categorized by IUCN as an Endangered species. Ex situ and in situ conservation are required to protect this species

Abstract

Mangroves, as one of the vegetation types that is a natural stronghold from coastal disasters, also function as a shelter and find food for various biota in coastal ecosystems. Therefore, protecting the mangrove ecosystem from degradation is very important. One effort that needs is ecosystem rehabilitation through mangrove planting in coastal environments. To support it, a design was devised using drones and remote-sensing vehicles to assist in making mangrove planting designs. This research was conducted in Jenggalu Estuary, Gading Cempaka District, Bengkulu City. This research aims to study the use of drones in mapping potential mangrove planting areas and designing a mangrove planting plan to rehabilitate coastal ecosystems. In mapping using drones, the height used was 80 meters with 80% overlap, and 2.87 hectares of potential mangrove planting area was obtained. Based on the research results, drones in mapping are very useful in calculating the area of potential mangrove planting areas and designing effective planting plans. There are four scenarios for planting mangroves with a spacing of 0.5 m, 1 m, 2 m, and 3 m, respectively. For a planting area of 2.87 ha, the number of seeds needed is 114,800 planting points for a distance of 0.5 m, 28,700 planting points for a distance of 1 m, 7,175 planting points for a distance of 2 m, and 3,189 planting points for a distance of 3 m

Abstract

PT. Pertamina Hulu Rokan (PHR) is conducting activities to restore unproductive lands by revegetating in 3 types of areas. They are (1) areas of ex-well pad facilities where well plug & abandon (P&A) activities have been carried out, including the dismantling of related surface facilities, (2) areas of ex-production facilities that have been dismantled and (3) areas of ex-borrow pits. This research was conducted in PHR’s post-operation land area in 5 revegetation sites representing three types of post-operation areas, in Riau Province. The purpose of this study is to identify the types of vegetation found on post-operation land of oil and gas mining and to determine the types of vegetation that grow well on post-operation land based on the revegetation achievement target in each post-operation location in the document of Environmental Impact Analysis. Field research was conducted through the observation method. Observations were made by observing the type of plant, plant height, and plant mortality rate. The results showed that there were ten species of plants found in the 3 types of post-operation land in PHR, namely Cempedak (Artocarpus integer), Durian (Durio zibethinus), Jelutung (Dyera lowii), Jengkol (Pithecellobium jiringa), Mahoni (Swietenia macrophylla), Mangga (Mangifera indica), Matoa (Pometia pinnata), Medang (Litsea sp), Petai (Parkia speciosa), and Pulai (Alstonia scholaris). In total, the percentage of living plants was 88.2%. Furthermore, the average plant height in the five post-operation land areas was 169.8 cm. These values also indicate that the percentage of living plants and the height average of each type of plant in location is categorized as good, according to the achievement of the revegetation target in the document of Environmental Impact Analysis
