Abstract

The objective of this study is to investigate life asset condition and household life recovery strategy after and before earthquakes in Tandikek, Padang Pariaman District. Livelihood index assessment is used to describe  livelihood asset changes before and after the earthquake. A descriptive analysis is employed to describe life recovery strategy that is used by households in various level and phase of house damages. The result of the study shows that change in household life asset after the earthquake has U pattern, meaning that condition of assets for all indicators decreased during emergency and recovery phases. This condition, however, increased after recovery phase up to the present time. The condition is even better than that prior to the earthquake. This also means that all recovery efforts have successfully developed  people’s life assets that guarantee their life after the earthquake. The livelihood recovery strategy used by households in Tandikek to maintain and recover their livelihood varies according to the level and phase of the house damage. The households that take independent livelihood strategy, either in active or passive way,  networking strategy and utilization of disaster aids from various sources appear to recover faster than those who only take one strategy.

Abstract

In the tourism sector, hotel industry is one of the most important sub-sector. This hotel industry emits greenhouse gas (GHG) emissions mainly carbon dioxide (CO2) by consuming large amount of energy, water, and non-renewable resources in service operation everyday on basis. This paper presents results of analysis how much does the GHG emissions release in hotel. The Asian Institute of Technology Conference Center and Chiang Mai Hill 2000, Chiang Mai, Thailand have successfully estimated GHG emissions by using Bilan Carbone® tool. The mitigation options are to encourage low carbon dioxide hotels. The data collection was done by questionnaires, interviews, and observations in both of them hotels. The results of annual GHG emissions contributor both Chiang Mai Hill 2000 as 3,844 t CO2 and at AITCC about 1,011 t CO2. Energy use is a major emission contributor followed by travel, property, input material, waste generated, and freight. Higher number of guests/tourists flow, effected higher used of facilities such as electricity, air conditioning, lighting, and food & beverage. Larger size hotel service quality, greater guest room service, wide range of building area, greater facilities, and large functional are consumed higher energy and materials. As well as, the higher rate of room turning can also increase of emissions. Moreover, Chiang Mai Hill 2000 tends to take transportation which have longer distance than AITCC. Therefore, increasing higher journal distance generated higher GHG emissions as well. The short term and long term mitigation plans can also be taken into consideration to reduce GHG emissions. The recommendation of short term mitigation plans can be applied directly in both hotels thus, increasing awareness about climate change and energy conservation among uses. The long term mitigation plans recommends to give “Green Hotel” award to successful hotels for reducing GHG emissions in hotel. These plans can be incorporated the Thailand’s government policy to reduce the impacts of climate change to the hotel industry.

Abstract

The construction of dams in many cases has led to forced displacement and resettlement of about 40-80 million people worldwide. Several studies have reported that Development Induced Displacement and Ressettlement (DIDR) cause negative impacts on living standards and livelihood outcomes of the resettled communities. Koto Panjang Dam has been in operation for 20 years. The impact of settlement movement due to the construction of a long Koto Panjang dam is also experienced by second generation resettlers. The objectives of this study were: a) to assess the profile access and control on household farming livelihood of second generation of resettlers, and b) to assess the level of household welfare of the second generation in Koto Panjang hydropower region, Riau Province.  All second-generation households in Koto Mesjid and Pongkai Istiqamah were taken for samples (92 households).  Profile access and control on households farming at the site of this study showed that men still dominated in access and control on farm management such as: land, working, credit, means of production, breeding, pest and disease control, education, training, and agricultural extension. Women were more dominant in processing and selling the yields. The poverty experienced by households in Koto Masjid village was largely due to limited land ownership, while that experienced by households in Pongkai Istiqomah village was due to the dependence of livelihoods on the rubber plantation, in addition to the limited field of other businesses in the village.

Abstract

The habit of Karang Joang people is throwing garbage, inherited from generation to generation. Most of treating’s their garbage are by burning it in the yard, throwing into the garden or the river. The transportation to take garbage that isn’t intensive by city officers and the lack of knowledge in managing the garbage greatly affects the pollution condition of the air, soil and water in the village. This research focuses on the patterns of society in treating organic waste and inorganic. Environmental conditions in the village to make some attention from the city government Balikpapan. Because the village is located in a protected forest manggar should be kept clean. We distributed questionnaires to 500 housewives that are living in 12 areas near the river. We interviewed one of the small shop and 5 housewives about what they buy and how dispose of waste in one day. Approximately 5-7 sachet plastics and around 200-300 grams of organic garbage. And approximately one drum of water is used for one family. Six months after distributing questionnaires and analyzing, we held a workshop with theme on the importance of eco-friendly living, composting of organic garbage, and counseling about bank of garbage program for 32 leaders in the village. Then we try to find solutions about how to build the consciousness and management in solid waste. In this study, some possible solutions have been presented by transfer environmental technologies

Abstract

Calli is one of the materials used for genetic transformation. Studies on calli induction in some pepper genotypes were conducted in the Plant Tissue Culture Laboratory of the Faculty of Agriculture, Andalas University, Padang. This study aimed to obtain calli which can be used as material for genetic transformation. We used three genotypes of chili (Kopay, Kampung and Trisula). Explants were derived from first leaf, cotyledon, epycotyl and hypocotyl obtained from 24 days old chili germination. The study found that all the explants were able to produced calli. From 17 combinations of medium, the two combinations that produced 100% calli were MS + BAP + IAA + L2 vitamin and MS + 2,4 D. Mediums that can produce organogenic calli were MS + BAP 4 mg / L, IAA 0.5 mg / L, L2 vitamin ( Pyridoxin hydroklorit 0.5 g / L  and Thiamin hydroklorit 0.1 mg / L). The colour of calli produced were yellowish green and compact. The study also found that structures develop with a globular phase, followed by a heart shape, torpedo, cotyledonary and eventually form buds. While MS + 2.4 D 4 mg / L produced yellowish white calli and crumb, it could not grow organogenic calli.

Abstract

We live in the Anthropocene, at a time when the human footprint is at its most pronounced. In the process ofrapid urbanization, that characterizes today's age, many ecological commons with complex histories ofgovernance and stewardships are reimagined in keeping with prevailing notions of their utility. This redefining of acommon often occurs in exclusion of former social and cultural relationships built around the resource leading toentire communities being disconnected from it. The resultant loss of perceived value can enhance vulnerability tothreats including a loss of its identity as an ecological common. In this paper, we use the case of a former lake (Sampangi lake) within the south Indian city of Bengaluru toillustrate what makes understanding the past so important when it comes to management of urban ecologicalcommons. The Sampangi lake, now a major sports stadium of the city, was once an important ecological, social,and cultural resource. Besides being an indispensable water source to the city up until the mid-19th century, thelake also supported various other forms of provisioning and cultural ecosystem services – ranging across servingdomestic purposes, livelihoods, and belief systems. How then did this lake fade into obscurity and eventualoblivion in the intervening years, and more importantly, what happened to the people who once had strong ties withthe resource? Do events of long ago resonate even today and if so, how do they still speak to us? In order to answer these questions, we combine landscape change analysis through geospatial methodsalong with official archival records and oral narratives to unravel the story of change and its impacts on this urbancommon. We examine different changing notions of the utility of this lake pictured against a backdrop of rapidurbanization, migration, and landscape change. We relate this historical picture with contemporary trends in lakemanagement to draw a parallel. In so doing, we demonstrate that obtaining knowledge about the history of aresource, the history of its use, the various stakeholders accessing it, and the various conflicts it witnessed can helpprevent exclusionary histories, alienation of communities, and encourage citizen stewardship of the resource. Thiscan further shape more equitable, ecologically robust policy frameworks aimed at enhancing social and ecologicalresilience and therefore longevity of the resource.

Abstract

The research aims to see the level of entrepreneurship of vegetable farmers in six sub-districts in Kabupaten Agam, particularly specialized and diversified vegetable farmer. The research is explanatory research, using 200 respondents taken by quota sampling proportionally. Farmer entrepreneurship level is measured using the Entrepreneurship Behavior Index (EBI). The result shows the overall level of entrepreneurship of vegetable farmers in six districts in Kabupaten Agam in the medium category that is equal to 69%,  Farmers who specialize in vegetable crops have higher levels of entrepreneurship than vegetable farmers who choose to diversified vegetable cultivation. The specialized vegetable farmer  have greater degree of decision making ability compared to diversified vegetable farmer. Diversified vegetable farmer concerned more on economic motives than specialized farmer. Risk taking ability also revealed difference tendency  among specialized and diversified vegetable farmer. Specialized vegetable farmer have bigger information seeking  capability, meanwhile diversified vegetable farmers are stronger for their leadership capability. The implications of this study that the entrepreneurial spirit vegetable growers is a variable that can provide reinforcement for the implementation of specialized cultivation systems. This means that if the entrepreneurial ability of farmers can be further improved, then with the application of specialized cultivation systems in vegetable crops, farmers will be able to create value-added products or produce derivative products from vegetable commodities produced.

Abstract

This study aimed to determine the effect of fermented coconut waste on the growth of catfish (Clariassp). The study design used was completely randomized design (CRD) with 4 treatments and 5 replications. Treatments included P0 (0% of fermented coconut waste in the feed), P1 (10% of fermented coconut waste in the feed), P2 (20% of fermented coconut waste in feed), and P3 (30% of fermented coconut waste in the feed). The observed variables were feed consumption, absolute body weight, feed conversion and survival rate. The results showed that using fermented coconut waste for catfish diet significantly (P <0.05) affected feed intake, absolute body weight, feed conversion and live survival of the fish. The conclusion of this research was using 20% of fermented coconut waste in the diet can increase the growth of catfish (Clariassp).
