Abstract. Rahmawaty, Samosir JB, Batubara R, Rauf A. 2019. Diversity and distribution of medicinal plants in the Universitas Sumatera Utara Arboretum of Deli Serdang, North Sumatra, Indonesia. Biodiversitas 20: 1457-1465. The plants found in Universitas Sumatera Utara (USU) Arboretum has the potential to be utilized by the local community to meet their food and medicinal needs. The objectives of this study were to calculate the species diversity, to find out the various parts of plants utilized for medicinal purposes and to map the distribution of medicinal plants in the arboretum. Survey and interview methods were used to collect data. The species diversity was determined using Shannon-Wiener index. Geographic Information System (GIS) was used to map the distribution of medicinal plants. The results showed that there were 17 species of medicinal herbs, 21 species of trees and 12 species of poles in the arboretum. The diversity was classified as moderate based on the calculated value. The most predominant part of plants utilized for medicinal purposes were leaves. The distribution of medicinal plants was mostly clustered and uneven. The condition indicates still there is scope for additional planting of medicinal species to increase the diversity of species, especially in the western and the northern part of the arboretum.

Landslide Disaster

Jember regency has several areas that are morphology of folding hills and mountain folds. The part of landslide prone zone is closely related to the slope of the slope. Areas with a sloping slope of more than 15º need attention to the possibility of a landslide disaster. Interconnection contacts with weathering of rocks, settlements and land cover also affect the landslide potential. The existence of Ijen Volcano that produces volcanic rock deposits that are generally not yet unified will increase the potential for landslides in Jember Regency. Landslide has occurred one of them on Gunung Gumitir Street which is the main route of Surabaya-Jember-Banyuwangi traffic. In May 2016 this street is hit by landslide, so the flow of traffic through this lane is paralyzed and must be diverted to a further path, which rotates to Situbondo City. The transfer of this pathway resulted in a loss to the local community and who crossed the path.The occurrence of landslide disaster shows that Jember Regency area is vulnerable and potentially return to landslide. Therefore there is a need for a solution to solve this problem. One solution to solve the problem is by utilizing Geographic Information System (GIS) application. The purpose of this research is to analyze zonation prone to landslide in jember district. The design of the research is Geographic Information System overlay analysis. This design combines several parameters in the determination of landslide-prone zones. This design combines several parameters in the determination of landslide-prone zones. The parameter used in this research is (1) land use, (2) topography, and (3) soil.Based on the research results, it can be known zone with highest to lowest vulnerability level. Zone with very high level of vulnerability is located in Panti sub-district, Sumberbaru, Sukorambi, Dyke, Silo and Jelbuk. The zones have similar characteristics that include (1) soil type of andosol, (2) clay texture, (3) uncompacted rock, (4) slope of 30⁰-40⁰ (steep and very steep), and (5) land use for settlements and plantations.

AbstractAir pollution in Malaysia is largely attributed to motor vehicles and land transportation, industrial activities and open burning. It has a hazardous effect on the public’s health and the environment. This study focuses on the spatial analysis of carbon monoxide (CO) and ozone (O3) concentrations trend in Klang Valley stations, specifically in Klang, Petaling Jaya, Kajang, Shah Alam and Cheras from 2000 to 2009. The study used the Inverse Distance Weighted (IDW) interpolation technique under the Geographic Information System (GIS). This study found that the distribution pattern of CO spatial concentrations in the Klang Valley is the highest concentration and reached 2.5 ppm, especially in Klang and Petaling Jaya stations in 2002 and 2003. However, the annual concentration of O3 recorded in Klang, Petaling Jaya, Kajang, Shah Alam, and Cheras stations from 2004 to 2009 is between 0.01 to 0.025 ppm. While air quality legislations have been introduced in Malaysia, policies and regulations being established by the government, their enforcement is still weak. Subsequently, air pollution is still a significant issue in Malaysia. Strong cooperation between the government, stakeholders and the local community is important to promote environmental sustainability and improve the community’s well-being. Keywords: Air pollution; Geographic Information System (GIS); Air Quality Policy; Malaysia

The role of BBM is very important in people's lives. Fuel is a basic need for rural and urban communities, both as household needs and as business needs. The existence of kerosene in Jayapura is quite evenly distributed. From the results of survey conducted by the OFFICE OF INDUSTRY, COOPERATIVE TRADE AND SMEs that every year the use of LPG as fuel for cooking is still very low, while the use of kerosene from year to year is widely used by local community, it causes more kerosene bussiness but people have difficulty getting information about the location to get the kerosene, therefore we need a system that can help find the location, namely geographic information system that can provide information about fuel oil base points. This system is in symbols form for making the system using QGIS with the PIECES analysis method, the design using Unified Modeling Language (UML) method and the development method using waterfall method. This research produces a system that can be expected to make it easier for the public to know the distribution of kerosene in Jayapura

AbstractMapping potential disasters and problems is the basis for knowing disaster risks that will occur. Wojo Village is one of the villages in the southern region of Malang Regency which has the potential of a tsunami disaster. The potential of the tsunami disaster was realized by the community since the cessation of the mining cooperatives in 2015 on Golo Beach. The activity of mapping potential disasters and problems utilize the Participatory Geographic Information System (PGIS) method. This method was carried out by inviting several group representatives to conduct focus group discussions (FGD). The aim is to find potential disaster funding problems according to the perspective of the local community. The result of the process of mapping potential disasters and problems is the emergence of different perspectives between men and women invited as representatives. The male representatives present were able to draw on the map regarding the potential for disasters and the problem in the village was one of which was a tsunami, whereas women's representatives actually looked at potential disasters and problems from the perspective of the family's economic stability. Some male representatives stated that the threat of the tsunami became a male area of control while women's representatives guarded Brahma cattle. When referring to these results, women's groups become gender groups threatened by the risk of a tsunami disaster.   Pemetaan potensi bencana dan masalah merupakan upaya dasar dalam membaca risiko bencana sebelum bencana tersebut benar-benar terjadi. Desa Wojo merupakan salah satu desa yang berada di wilayah Kabupaten Malang sebelah selatan yang memiliki potensi bencana karena masuk ke dalam daerah rawan tsunami. Potensi bencana atas tsunami terbaca oleh masyarakat desa justru setelah berhentinya operasional salah satu koperasi pertambangan di Pantai Golo tahun 2015. Kegiatan pemetaan potensi bencana dan masalah dilakukan dengan menggunakan metode Participatory Geographic Information System (PGIS). Metode ini dilakukan dengan cara melakukan penglibatan perwakilan dari beberapa kelompok yang dilakukan dengan model focus group discussion (FGD) dari perwakilan perangkat desa, karang taruna, kelompok tani, kelompok wisata, dan kelompok perempuan. Tujuannya adalah ditemukannya potensi bencana dan masalah berdasarkan sudut pandang masyarakat setempat. Hasil dari proses pemetaan potensi bencana dan masalah adalah munculnya sudut pandang yang berbeda antara laki-laki dan perempuan yang diundang sebagai perwakilan. Perwakilan laki-laki yang hadir mampu mengambarkan dan menuangkan ke dalam peta terkait potensi bencana dan masalah di desa mereka salah satunya adalah rawan tsunami, sedangkan perwakilan perempuan justru memandang potensi bencana dan masalah dari sudut pandang pencapaian kemapanan ekonomi keluarga. Beberapa perwakilan laki-laki menyatakan bahwa masalah dan bencana tsunami merupakan wilayah pengawasan laki-laki sedangkan beberapa perwakilan perempuan menyatakan bahwa menjaga sapi jenis 'Brahma' menjadi upaya terpenting untuk menyelamatkan desa dibandingkan sadar akan potensi tsunami. Bila merujuk pada hasil tersebut maka kelompok perempuan menjadi kelompok gender yang terancam atas risiko bencana tsunami.

Abstract. Rahmawaty,  Frastika S, Marpaung RME,  Batubara R,  Rauf A. 2019. Short Communication: Use of Geographic Information System for mapping of Aquilaria malaccensis land suitability in North Sumatra, Indonesia. Biodiversitas 20: 2561-2568.  The Geographic Information System (GIS) can be applicated in the field of forestry and agriculture, such as for mapping as part of land evaluation. The land suitability of Aquilaria malaccensis in the agroforestry land of North Sumatra Province is important.  Commonly, A. malaccensis were planted by the community in Langkat and Deli Serdang District. This study aimed to map the land suitability for A. malaccensis in Telaga Village, Sei Bingai Sub District, Langkat District, Peria-ria Village and Sari Laba Jahe Village, Biru-biru Sub District, Deli Serdang District. A survey method was used to collect soil samples in the field. Land suitability classification (LSC) for A. malaccensis was evaluated based on the matching method.  The results showed that the actual land suitability classes for A. malaccensis in Telaga Village were moderately suitable (S2) and marginally suitable (S3). The actual land suitability classes for A. malaccensis in Peria-ria Village and Sari Laba Jahe Village were moderately suitable (S2), marginally suitable (S3) and not suitable (N). There were several limiting factors in land suitability evaluation in the area, namely: nutrient retention (nr), erosion hazard (eh), and root zone medium (rc).
