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

A study has been conducted on the crop-livestock integration innovation using palm oil by-products technology to support beef cattle production in 2014. The collected data consisted of (i) Socio-economic aspects, (ii) The body weight gain of cattle, and (iii) Palm oil production. These data were taken from Sri Langgeng farmers group (13 respondents) in Dharmasraya district and Tanjung Keramat farmers group (10 respondents) in West Pasaman district. The results of the socio economic aspects showed; the  average age of farmers was 39 years old, owned palm oil plantation of 2,2 and, 4,1 ha, and owned of 4.2 and 6.2 head of cattle in Tanjung Keramat and Sri Langgeng respectively. The average monthly income was Rp 1.63 million and about Rp 1.05 million derived from livestock contribution in Tanjung Keramat, and Rp 1.65 million and about Rp 1.71 million derived from livestock contribution in Sri Langgeng. Feeding a supplement of palm oil by-products increased cattle growth by about 0.14 and 0.09 kg/head/day at Sri Langgeng and Tanjung Keramat respectively. In contrast, the animals in a control treatment experienced body weight losses of -0.17 and -0.11 kg/head/day. The application of organic fertilizer from cattle manure, above the inorganic fertilizer, increased the palm oil fruit by 39.4% and 48.4%. The research proved that there is an opportunity to accelerate the adoption process of crop-livestock integration in palm oil plantation areas in West Sumatra.

Abstract

Food security issue after 2008 global-crisis is something relate with the climate change phenomenon which had worsened on the last few decades. The impact of global climate change can be seen from the fluctuation of main crops production yield in tropical countries. This has affected the food price fluctuations particularly on the grain price, both international and domestic markets. The rice-commodity, known for its thin market characteristics, is now also experiencing the fluctuation of production, its productivity and also the rice price. Considering the importance of rice as the main staple food in Indonesia, the purpose of this research is to identify the Indonesia’s rice price fluctuation (volatility) and to investigate how far climate change affects the Indonesian paddy production and rice price volatility. By applying monthly time-series data from 2007 to 2014, this research used ARCH-GARCH methods to find out the rice price volatility and VECM (Vector Error Correction Model) to investigate the impact of climate change phenomenon on the Indonesian paddy production, as well as rice price volatility both in the short-run and long-run. The result is important for the stakeholders and government in preventing the risk and uncertainty condition of paddy production and rice price fluctuation caused by climate change

Abstract

It has been said that development requires sacrifice. This has been the experience of households living in Koto Panjang, Sumatra, Indonesia. Because of new dam construction, they have had to move to new settlements provided by the government. The displaced community consists of 4868 families from 10 villages. Many problems have arisen due to this removal. This study examines the influence of household participation and compensation on household welfare by using a Structural Equation Model. The sample consisted of 360 household heads from 12 villages in Koto Panjang whose households had been moved. The results show that compensation positively and significantly affected household welfare, while household participation could not be proven to affect household welfare.

Abstract

Salacca (Salacca edulis L.) is a tropical plant with a high economic value. The sexes of salacca can be grouped as dioecious, monoecious, dan hermaphrodite. Farmer's success in cultivation is especially determined by the male to female ratio. The present ratio of male and female plants is 1:4. Determining sex based on morphological characteristics is not effective and difficult for young plants (seedlings), also to lysozim marker and chromosome. Marker Assisted Selection is a strategy to determine sex using a marker. Random Amplifed Polymorfism DNA (RAPD) is an amplification technique that uses markers. Of 305 primers tested, 4 primers, OPO-17 produced 297 bp product, OPAP-20 produced 554 bp as the specific fragment for the female and UBC-454 produced 934 bp as the specific fragment for the female and UBC-454 produced 946 bp as male, primer UBC-78 with the size of fragment 562 bp as the specific fragment for the female.

Abstract

At the end of 2015, this study has been conducted to describe the planning; process; and evaluation of collaborative training using a comparative approach, 220 and 44 beef cattle farmers participated as informant in both types of - collaborative and non-collaborative training respectively. Fifteen informants representing stakeholder provided primary data. Both primary and secondary data were analyzed by using qualitative and quantitative approaches. The results showed that planning was based on an effort to accomplish the discrepancy of cattle farmer technical competency to perform breeding program. Process of conducting collaborative training focused on group management and keeping beef cattle. In non-collaborative training was on recording technics to prepare the issue of breeding cattle certificate. Collaborative training was assisted by a number of stakeholder facilitators, but, non-collaborative training was carried out by facilitators from an institution. Improvement of farmer technical competency has shown by adding of 58.41 % of cattle population, although there was an increasing of participant cognitive domain by 43.53 % at collaborative training. The recommendation advised that management and keeping cattle technical competency are continiously acquired for the half of groups (54.5%), while recording improvement should be taken into account at all groups (100 %).

Abstract

This study aims to assess the performance of farming practices of Lampai Kuning rice as an improved variety. Data were collected using survey method that relied upon primary data generated during the 2016/2017 production season. Data were collected through the use of a set of structured questionnaire administered on thirty farmers in Nagari Aie Angek, Sijunjung Regency. Stata version 12 was used to test the stochastic frontier model to measure the efficiency of Lampai Kuning rice.The results showed that the use of manure and Urea had negative effect on the Lampai Kuning rice, while the use of NPK had positive effect. The level of technical efficiency of Lampai Kuning rice was very low at the 0,55 level. The study reveals that large land size led to high Lampai Kuning rice production. Farmers could double their rice production by using factor of production appropriately.

Abstract

The regional approach in agricultural development has only been limited to the concept and has not been implemented in real terms. Various forms and models of agricultural development policy using the regional approach cannot prove that the indicators of regional approach have existed and been applied in agricultural areas. The development of agriculture so far has only been sectoral. This indicates that the concept of agricultural development through regional approach has not been implemented in real condition. In development through regional approach, the synergies among sectors and among economic activities are compulsory. The production central area (PCA) approach is one of the agricultural development approaches based on regional economic development theory. This research aimed to assess how area production center as a model of agricultural development that had considered regional concept, could be success in developing regions. The respondents were layer hen breeders residing in PCA location and Non PCA (50 respondents each).The study reveals that the value of agglomeration profits of large scale economies (SEI), localization economies (LEI), capital and labor showed positive and significant effects on layer hen production at PCA location. To further increase commodity production in PCA, the agglomeration profits as a regional approach variables should be part of the PCA analysis to improve productivity, efficiency and provide added value for farmers/breeders.

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.
