Abstract

Padang City is one of the cities threatened by tsunami hazard in Indonesia. There have been many government efforts to reduce casualties and physical damage to development. But there has not been a focus mitigation step discussing the trauma healing. This research aims to develop a model of trauma healing policy for the mitigation of tsunami disaster in Padang. This research is qualitative research using the Analytical Hierarchy Process (AHP) as data analysis. The results of the study using three criteria i.e resources, education, and social values, religion and culture of society. These three criteria, in a succession of 4 policy priorities, i.e a) the enhancement of the resource psychiatrist/counsellor/therapyhis; b) Involvement of family and school citizens in the trauma healing Program; c) The increase of social, religious and cultural values in the process of trauma healing; and d) the implementation of non-farmalogi therapy programs that are targeted to disaster victims tailored to the needs. The priority of these policies can be achieved by implementing various program activities taking into account the implementation time and budget cost.

Abstract

The red calliandra is a fuel wood crops that gave benefit for people. Recently, it is getting wide attention due to its important use as biofuel in industrial scale. The massive propagation is needed to meet industrial needs. Beside the use of conventional seedling production technique, the use of tissue culture for mass propagation is one of the alternatives to address this problem. This research was conducted to develop standard protocol for micropropagation of red calliandra through tissue culture. Here, the first step for that purpose was reported. The MS medium was used for basal media treatment. The seed source was stored for eight months under 5oC. This research was carried out in two stages i.e. 1) seed germination test and 2) shoot initiation and multiplication treatment. Each stage was arranged in experimental method. The result showed that seed were pre-treated with warm water (40oC) gave 62.5% germination under red light when compared to control (37.5%, pre-treated with water at 25oC under white light) three days after planting. Conversely, there is no striking differences of germinated seed percentages between light treatment at 25oC. Furthermore, it was found that addition of 2 mg/L BAP gave better result in shoot initiation and number of shoots formed from nodal explants after four weeks in treatment media. These results indicated that mass propagation of red calliandra can be done through tissue culture where multiplication stage is one of the important steps to produce multiple shoots only from single nodal explant.

Abstract

Red calliandra is one of woody plants that has been extensively developed as biofuel. Tissue culture techniques are employed to produce a large and uniform quantity of seedlings in a relatively short period. Previous stages of in vitro initiation and multiplication of shoot from calliandra explants have shown promising results. The shoots that were multiplied by in vitro technique need to be induced for rooting process to produce plantlets. These plantlets are then prepared for the subsequent acclimatization process. This research was conducted in two stages; root induction of shoots using a modification of MS half-strength media (MS ½) supplemented with 1-4 mg/L 1-naphthaleneacetic acid (NAA), and acclimatization of the plantlets into soil media. The results shown that MS ½ medium and media supplemented with 1 mg/L NAA were suitable for root induction, particularly to induce the root length. Furthermore, MS ½ media supplemented with 1-2 mg/L NAA stimulates the increment of plantlet height and leaves numbers. Plantlets which were transferred into soil exhibit robust growth during 3-weeks of acclimatization process, up to 100% plantlets survived during this stage. These results underscore the potential of tissue culture techniques in providing large scale calliandra seedlings production for future biofuel development.

Abstract

Open-pit gold mining has greatly affected the ecological balance by altering soil properties and reducing natural vegetation cover. Reclamation efforts through soil and vegetation recovery are therefore essential to help rebuild the disturbed ecosystem. This study examined how the Normalized Difference Vegetation Index (NDVI) relates to soil physicochemical properties in the Martabe gold mine reclamation area, North Sumatra, Indonesia. Vegetation recovery at different reclamation ages was analyzed using multitemporal Landsat 8 images. Soil samples were taken from the same locations at depths of 0-15 cm and 15-30 cm to observe changes in soil characteristics. Data were analyzed using Principal Component Analysis (PCA) to identify the main factors linking vegetation and soil conditions. Key ecological indicators were determined through the Minimum Data Set (MDS) approach. The PCA results indicated that the primary components explained 90.7% of the variation in soil physical properties and 74.6% of the variation in chemical properties. Important indicators of the ecological recovery were NDVI, bulk density, porosity, aggregate stability, organic carbon, total nitrogen, cation exchange capacity (CEC), and base saturation. The rise in NDVI values coincided with improved soil conditions, showing a relationship between vegetation re-growth and soil quality improvement.
