Authors: Basri H , Rusdi M , Lubis N R 
Published: March 2021

Abstract
Referring to The Center for Research on the Epidemiology of Disaster (CRED) data shows that landslides are responsible for at least 17% of all fatalities from natural hazards worldwide. One of the disasters that commonly occur in Indonesia is landslides, especially in Tangse Sub-District, Pidie District, Aceh Province. The main objective of this research was to determine the parameters and the weight of each parameter that causes landslide susceptibility by using expert judgement criteria. The expert decision can be accepted if the Consistency Ratio (CR) <0.1. The results showed the value of CR from 0.04 to 0.3. Expert judgement decisions with a value of CR = 0.04 (<0.1) were the most reasonable criteria of parameters for mapping landslide susceptibility. Those parameters were slope (42%), rainfall (36%), soil type (12%), and land use (10%). By using these criteria, there were four classes of land susceptibility in this area, namely very high, high, moderate, and low covering an area of 805.40 Ha (1.03%), 46,526.72 Ha (59.27%), 30,600, 38 Ha (38.98%), and 573.61 Ha (0.73%), respectively. Disaster mitigation could be carried out by socializing the vulnerability of landslides, soil protection through slope stabilization, and vegetative conservation.

Abstract
The food packaging industry is the largest sector of the plastic industry, accounting for 40% of the total (conventional) plastic demand. Conventional plastic packaging has significant practical advantages, in protecting packaged foods from contamination and the loss of food quality. Plastics are made up of repeating small units called ‘monomers’ that bind together to form the long chains called ‘polymers’ However, conventional plastics have detrimental effects human health, wildlife, and the environment. Many developing countries are overwhelmed with the plastic waste emitted to the oceans. Indonesia is the second biggest emitter of plastic waste, after China. Biodegradable plastics (bioplastics, green plastics) are an alternative for saving our environment. Bioplastics or biopolymers, are made from at least 60% natural materials, mostly of plant based origin, but they have several drawbacks: (i) lower mechanical properties; (ii) bad thermal stability; (iii) relatively low gas barrier properties. This lab-based study investigates the enhancements to mechanical, thermal and gas barrier properties of bioplastics through addition of nanocomposites derived from clay minerals (nano clay). The resulting product was examined under Scanning Electron Microscope (SEM). This paper summarizes the clay concentrations and mixing temperature conditions that are required for the enhancement of bioplastics.

Abstract
The exploration and development of organisms producing Omega-3 have escalated in order to fulfil the high demand for Omega-3 in every sector, especially in human health. Microalgae are one of the highlighted microorganisms due to their ability to produce edible oil or microbial oil containing Omega-3, such as Thraustochytrium, Ulkenia and Schizochytrium. Besides Polyunsaturated Fatty Acids (PUFA), the microbial oil from these microalgae also contains antioxidants and has been developed as an alternative source of Omega-3. The objective of this study was to identify the Omega-3 producing microalgae through genetic analysis. In this research we conducted a phylogenetic analysis based of 18S rDNA gene of a microalga isolated from mangrove leaves sourced from a mangrove area in Banda Aceh. The phylogenetic analysis was conducted using Neighbor Joining method with bootstrap analysis. The result revealed that the isolate was identified as a member of thraustochytrids family, which was consistent to the morphological analysis of the isolate from our previous research.

Abstract
Geospatial technology has developed rapidly and is widely used for various purposes related to geographic location. Aceh is one of the provinces in Indonesia as rice producer provinces. Aceh province contributes about 2 million tons of rice every year, with local consumption of about 650.000 tons. However, rice fields to support sustainability agriculture mapping in Aceh province are still not yet well verified. The shift of land use for non-agriculture is alarming; coincidently, spatial planning to meet the demand for agriculture activities for every regency in Aceh is another crucial issue. With this current situation, the use of geospatial technology is an essential tool. This article presents a geospatial technology for land use planning and sustainable agricultural mapping in Aceh Province, Indonesia, as a case study. Geospatial analysis combined with descriptive using existing spatial data supported by ground-truthing was carried out for this study. The result shows that geospatial technology, a combination of remote sensing data, a global positing system, and a Geographic Information tool, can represent comparison results from different data sources obtained from other studies. The result can also verify the existing data of paddy rice field to land use planning and agriculture mapping activities in Aceh Province.

Abstract
Based on the land use data of 1980, 2000 and 2018, combined with ArcGIS and fragstats4.2, the landscape index of the study area was calculated, and the spatiotemporal change process of landscape ecological risk in Qin’an County in the past 40 years was analyzed, which laid the foundation for the formulation of ecological risk control measures in the study area. The results show that: (1) from 1980 s to 2018, the landscape pattern of Qin’an County has changed obviously, the cultivated land decreased significantly, the construction land expanded obviously, and the expansion area mainly came from the transformation of cultivated land. From 1980 s to 2018, the landscape fragmentation of Qin’an County showed an overall increasing trend. (2) The landscape ecological risk level has a decreasing trend, the area of high risk area is significantly reduced, and the area of low risk area is increased. (3) From the spatial distribution analysis, the overall risk type of Qin’an County has an increasing trend from southwest to northeast. The high-risk areas are mainly distributed in the surrounding areas of Liuping, and the main landscape types in this area are cultivated land and grassland, which are easily disturbed by human activities; the low-risk areas are mainly distributed in Qin’an County, and the main landscape type is construction land, with strong anti-interference ability and lowest risk value.

Published: March 2021

Abstract
Global climate change has created an increasing number of environmentally displaced people (EDPs). As for the placement of EDPs, we analyze the problem from two aspects. On the one hand, we calculate the number of persons who may become EDPs. We build the EDPs Prediction Model Based on RBF Neural Network to predict the number of EDPs in some countries along the Pacific coast in 5 years. The results demonstrate that Maldives will have the largest number of EDPs, about 9,758 and Australia will have the smallest number, about 873. On the other hand, we analyze the national ability to resettle EDPs. We choose a number of countries with different economic conditions and cultural backgrounds, and analyzed their Receiving Capabilities, Receiving Pressure of EDPs and Crisis Tolerance to provide a basis for placement of EDPs. For the resettlement formulation of policies for EDPs, we first design the Network Flow Migration Model. Then, we optimize the impact coefficient of EDPs on culture, and give EDPs distribution policies in some countries. Considering the personal choices, migration situation and culture beliefs of EDPs, we use the Multi-Objective Optimization Equation to optimize the network flow model. Finally, we propose the policies to resettle EDPs and protect culture according to the risk of culture loss and the resettlement ability of different countries.

Abstract
A novel health hazard assessment model of fine particles generated from five groups of coal-fired boilers is built based on AHP. In our assessment model, some important factors are taken into account, including the number from uncontrolled emission, and mass from uncontrolled emission, the particle size distribution of Rosin-Rammler function of fine particles, and the total content of toxic chemical compositions (including Cr, V, Mn, Ni, Pb, Cd, As, Se, Hg, OC and EC). By calculation, PM2.5 from the industrial grate-fired boilers are much more harmful to human health than those from the other types of coal-fired boilers, which is not recommended to choose grate-fired burners as a burner of a new boiler or a modification boiler. PM2.5 from industrial fluidized-bed boilers are more harmful to human health than that of utility CFB boilers; PM2.5 from the large-capacity utility pulverized coal boilers (⩾450MW) are more harmful to human health than those from the small-capacity utility pulverized coal boilers (<450MW). It is necessary to install a high performance dust removal device.
