Tsunami-induced coastal change: scenario studies for Painan, West Sumatra, Indonesia

Abstract: There exists a high probability of a great earthquake rupture along the subduction megathrust under the Mentawai Islands of West Sumatra in the near future. Six rupture models were used to assess the tsunami inundation and the accompanying sediment movement in Painan, West Sumatra, Indonesia. According to a worst scenario, the potential tsunami might hit the coast of Painan about 26 minutes after the rupture and the entire city could be inundated with a maximum inundation depth of about 7 m. Severe erosion may also occur in the near-shore region. Two scenarios, one scenario with a positive leading wave and the other with a negative leading wave, were selected to simulate the tsunami-induced morphological changes. A positive leading wave would cause severe erosion in the shoreline area and a large sandbar in the offshore area adjacent to the shoreline; a small amount of sediment could be deposited in the city area; a negative leading wave could cause moderate erosion in the further offshore area due to the strong retreating wave front, an offshore sandbar could form in the bay area, while no noticeable large area of sand deposit could be found in the city area. The difference in the erosion and deposition patterns between these two scenarios provides very helpful information in the investigation of historical tsunamis through tsunami deposits.

Performance of white organic light-emitting diode for portable optical biosensor

Abstract: A white organic light-emitting diode (OLED) with enhanced sensitivity has been demonstrated as a novel light source in a portable surface plasmon resonance (SPR) optical biosensor. A disposable broad-spectral OLED was employed on the leg side of isosceles trapezoid prism for a fixed angle of incident light. Bimetallic Ag/Au composition layers were used as sensing layers and their structures evaluated such that the wavelength resonance occurred at the peak of the light spectrum. The SPR signal detection applied differential intensities at two reference wavelengths. We show that the integration of a white spectral OLED on an SPR sensor improved the sensor's sensitivity by ∼19.29% compared to an SPR sensor system using a green OLED for a bimetallic Ag/Au sensing layer. The limit of detection (LOD) of 2.4 × 10−6 refractive index units (RIU) has been established in the range of refractive index samples (Δn) around 3.6 × 10−3 RIU. This optical sensor demonstrated the capability of rapid, real-time monitoring operation. The activation of self-assembled monolayer (SAM), antibody immobilization, and biomolecular interaction detection of immunoglobulin G (IgG) protein are recorded successfully with a detection limit around 40.3 pg/mL.

A Conceptual Model of E-Government Adoption in Indonesia

Abstract: This study aims to determine various factors are related with the process of e-Government adoption. Many researchers have traced the success factors of e-Government but are still partial. This research contributes not only in terms of technological factors but also the attitudes and behaviors of its users (personality traits) which is also influential in the process of technology adoption. In this research, will be developed an adoption model of technology in the context of e-Government. This model incorporates some best practices related to the diffusion of technology such as TRI, TAM, UTAUT, IS/IT Success Model, as well as other factors influencing the adoption of e-Government such as Trust and Compatibility based on previous research. The conceptual model proposed could bring better understanding about important issues especially in e-Government adoption process in Indonesia.

Keanekaragaman Jenis dan Sumber Plasma Nutfah Durio (Durio spp.) di Indonesia

Abstract: Indonesia is rich of genetic resources and species diversity of Durio spp. Based on examination of 270 number of specimens herbarium collection in Herbarium Bogoriense, there are 20 species of Durio (Durio spp.) encountered in Indonesia. Eighteen of 20 species of Durio occur in Kalimantan, 7 species in Sumatera and 1 species in Java, Bali, Sulawesi, and Maluku respectively. Fourteen of 18 of species Durio in Kalimantan are recorded as endemic species. Nine species are reported as edible fruits, e.i. Durio dulcis (lahong), D. exelcus (apun), D. grandiflorus (durian munyit), D. graveolens (tuwala), D. kutejensis (lai), D. oxleyanus (kerantungan), D. lowianus (teruntung), D. testudinarum (durian sekura), and D. zibethinus (durian). The results of study indicated that D. acutifolius, D. dulcis, D. kutejensis, D. lowianus, D. oxleyanus, D. testudinarum, and D. zibethinus are as the indigenous species of Durio (Durio spp.) having development potential in Indonesia. Abstrak Indonesia kaya dengan sumber plasma nutfah dan keanekaragaman jenis Durio (Durio spp.). Berdasarkan hasil pengamatan yang dilakukan di Herbarium Bogoriense terhadap 270 nomor spesimen herbarium kerabat durian (Durio spp.) di Indonesia telah ditemukan 20 jenis Durio. Delapan belas jenis di antaranya ditemukan di Kalimantan, 7 jenis di Sumatera, dan hanya 1 jenis masing-masing di Jawa, Bali, Sulawesi, dan Maluku. Empat belas dari 18 jenis Durio di Kalimantan merupakan jenis-jenis endemik. Sembilan jenis di antaranya dilaporkan sebagai buah-buahan yang bisa dimakan (edible fruits), yaitu Durio dulcis (lahong), D. exelcus (apun), D. grandiflorus (durian munyit), D. graveolens (tuwala), D. kutejensis (lai), D. oxleyanus (kerantungan), D. lowianus (teruntung), D. testudinarum (durian sekura), dan D. zibethinus (durian). Dari hasil penelitian ini dapat dilaporkan bahwa D. acutifolius, D. dulcis, D. kutejensis D. lowianus, D. oxleyanus, D. Testudinarum, dan D. zibethinus merupakan jenis-jenis Durio (Durio spp.) asli Indonesia yang berpotensi untuk dikembangkan.

Revealing Customer Behavior on Smartphones

Abstract: Recent development of mobile phones is very interesting as the new generation, known as “smart phones†, offer highly attractive features. The main advantage of smart phones is the ability to connect to the Internet from anywhere, consequently enabling them to remain continuously in touch with their social networks. This paper discusses how consumers in Brunei Darussalam (Brunei) responded to the survey of smart phones. A Theory of Reasoned Action Model is used to understand customers preference in choosing a specific product over the other. To assess the use of smart phones, the authors conducted surveys with consumers, stressing on product preferences, consumption behavior of smart phones, as well as opinions on the functionality of smart phones. The smart phone market in Brunei is dominated by the younger generation who is less sensitive towards price. In terms of usability, consumers prefer smart phones more than tablets or other mobile devices, the reason for their preference being the superior functional features which exist in smart phones.
