Aaptamine Derivatives from the Indonesian Sponge Aaptos suberitoides

2013

Four new aaptamine derivatives (1-4) along with aaptamine (5) and three related compounds (6-8) were isolated from the ethanol extract of the sponge Aaptos suberitoides collected in Indonesia. The structures of the new compounds were unambiguously determined by one- and two-dimensional NMR and by HRESIMS measurements. Compounds 3, 5, and 6 showed cytotoxic activity against the murine lymphoma L5178Y cell line, with IC(50) values ranging from 0.9 to 8.3 μM.

GraphoGame SI: the development of a technology-enhanced literacy learning tool for Standard Indonesian

2018

Early intervention programs are generally considered the most efficient and beneficial approach to providing support to struggling beginning readers. This paper discusses the theoretical background, development, and design of, as well as the first results obtained with, GraphoGame for Standard Indonesian, a technology-enhanced learning environment that trains the basic skills of reading by high but playful exposure to grapheme-phoneme coupling. The results of the pilot study assessing the usability of the program in 69 first-graders show that the more the students with low pre-test phonological skills were exposed to the game, the better their post-test performance on reading and decoding f…

Understanding eParticipation services in indonesian local government

2014

Published version of a chapter in the book: Information and Communication Technology. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-55032-4_32 This study aims at understanding how local government from a developing country, in this case Indonesia, implement and manage eParticipation services. In doing so, we combine institutional theory and stakeholder theory to build a sharper analytical lens. From an interpretive case study in the city of Yogyakarta, we reveal the institutionalization process of the services since their inception and identify major stakeholders and their salience. Based on our findings, we propose implications for practice and suggest implicati…

Habitat degradation correlates with tolerance to climate-change related stressors in the green mussel Perna viridis from West Java, Indonesia

2013

It is unclear whether habitat degradation correlates with tolerance of marine invertebrates to abiotic stress. We therefore tested whether resistance to climate change-related stressors differs between populations of the green mussel Perna viridis from a heavily impacted and a mostly pristine site in West Java, Indonesia. In laboratory experiments, we compared their oxygen consumption and mortality under lowered salinity (-13 and -18 units, both responses), hypoxia (0.5 mg/l, mortality only) and thermal stress (+7 degrees C, mortality only). Mussels from the eutrophied and polluted Jakarta Bay showed a significantly smaller deviation from their normal oxygen consumption and higher survival …

The Revival of Indonesian Skin Care Brands

2020

Skincare business in Indonesia has been growing enormously in the last decade, with the coming of international brands and the struggling of local brands, to win the Indonesian customers. The aim of this research is to analyze the influence of country of origin to purchase decision through the brand image, and the impact of country of origin on customer satisfaction for local Indonesian skin care brands. As this research is using the quantitative approach, the data are collected by using questionnaires which are distributed to selected samples of 179 respondents. The respondents are chosen from the consumers of Indonesian brands of skin care products. The data are analyzed with SmartPLS sof…

Trimeric Hemibastadin Congener from the Marine Sponge Ianthella basta

2012

The first naturally occurring trimeric hemibastadin congener, sesquibastadin 1 (1), and the previously reported bastadins 3, 6, 7, 11, and 16 (2-6) were isolated from the marine sponge Ianthella basta, collected in Indonesia. The structure of 1 was elucidated on the basis of 1D and 2D NMR measurements and by HRMS. Among all the isolated compounds, the linear sesquibastadin 1 (1) and bastadin 3 (2) showed the strongest inhibition rates for at least 22 protein kinases (IC(50) = 0.1-6.5 μM), while the macrocyclic bastadins (3-6) demonstrated a strong cytotoxic potential against the murine lymphoma cell line L5178Y (IC(50) = 1.5-5.3 μM).

Cytotoxic Isomalabaricane Triterpenes from the Marine Sponge Rhabdastrella globostellata

2006

Fourteen isomalabaricane triterpenes were isolated from the marine sponge Rhabdastrella globostellata. In addition to the known compounds globostellatic acids A (1) and D (4) and stelliferin riboside (13), 11 of the compounds were new natural products, which included globostelletin (3), eight new globostellatic acid congeners, F to M (2, 5-11), and two new stelliferin ribosides (12 and 14). The isolated compounds were tested against three different cancer cell lines, L5178Y (mouse lymphoma), HeLa (human cervix carcinoma), and PC-12 (rat pheochromocytoma). The isomalabaricane derivatives were found to be selectively active toward the mouse lymphoma cell line L5178Y. The structures were deter…

Aspects de la gestion des dolmens et des tombes collectives actuels dans les sociétés de l’île de Sumba (Indonésie)

2021

L’article présente une étude ethnoarchéologique dont l’objectif est de cerner les principales caractéristiques de la pratique de la tombe collective dans les sociétés traditionnelles de l’île de Sumba (Indonésie) et de montrer comment les éléments recueillis peuvent nous conduire à modifier notre manière d’appréhender les tombes collectives du Néolithique européen. Les sociétés sélectionnées sont les dernières au monde à construire des monuments mégalithiques dans le but d’en faire des tombes collectives. La maîtrise de l’arrière-plan social et religieux et une connaissance du vécu subjectif des individus impliqués constituent ici les principaux atouts de la démarche ethnoarchéologique. Dan…

Steering Institutionalization through Institutional Work: The Case of an eProcurement System in Indonesian Local Government

2014

Corruption is arguably one of the main hindrances to development. In their effort to combat corruption, governments in developing countries turn to information technology to enhance transparency in decision making. However, implementation of an information system in this context is not straightforward. Premised upon institutional theory, this interpretive case study traces the role of institutional actors in the institutionalization of an eProcurement system in Indonesian local government. It draws on different streams of research on institutional work to develop an interpretive lens to understand what institutional actors do to steer the institutionalization process. It identifies a set of…
