Ink made from zinc oxide (ZnO) nanoparticles colloid has been synthesized by using a sol-gel method. Employing an XRD, it was obtained that the sizes of particles were around 3–4 nm. Utilizing a UV-Vis spectrometer, it was found that the band gap energies were 3.5 and 3.45 eV for the sizes of 3 and 4 nm, respectively. For the purpose of testing the ink effectiveness, the ZnO colloid was mixed with polyethylene glycol (PEG) 400 or glycerine. Using pure ZnO colloid as printer ink, invisible characters under natural illumination had been successfully printed on specific papers. Under ultraviolet (UV) illumination, the invisible characters became visible. The developed ink, therefore, has potential applications for security of bank notes or passbooks.

Indonesia is exposed to climate change, especially with regard to the rising sea level, changes in precipitation and extreme events. This will particularly impact to many sectors in this country. In order to evaluate the impact on subsurface environment, groundwater temperatures in boreholes can be an important source of information on recent climatic changes. Subsurface temperatures in Jakarta city were analyzed to evaluate the effects. As a result the magnitude of surface warming was increase 1.4°C which agreed with the increase of air temperature meteorological data during the last 100 years. This is the preliminary results of significant increase in climate change during the last century in Jakarta. Still today, the information on vulnerability and adaptive measures is not sufficient in order to plan and design appropriate activities on the national level in Indonesia.

National Family Planning Coordinating Board (NFPCB) as Non Department Goverment Institution of RI have been facing environtment strategic changing. To arrive at the improvement, among the other methods, is organization transformation toward Learning Organization, where the organization member be able to develope their capacity continuously to reach the optimal result. The Indonesia NFPCB is a public birocracy which has core business and responsible on population policy development, birth control, and family prosperous development. The problemis how learning goes on in the public birocracy, and what are components related to the transformation toward learning organization. Reserach methodology applied interpretative, qualitative approach used phenomenology methods. The results of the research indicates that NFPCB organization is unable in transforming the learning organization. The learning organization is just conceptual framework, or knowledge, it is not an operational organization behavior. Finally the organization deffensive routine activities, unsystemic problem solving, innovationand experiment by applying the new approach are weak. The organization unable to learn from the past NFPCB succeed, which fruitfull on moving the community into the family planning programmes. The existance of having a new leader always there is a new hope that the NFPCB will arrived at the same succes as it is in the past. It isrecommended to internalize culture values of the organization to the whole organization member, and the leader should be able to revised the system to push all organization member to learn faster on increasing their capacity to face the strategyc environment changes.

MARKETING SECTOR DEVELOPMENT AS SUPPORT FOR FISHERIES INDUSTRIALIZATION (CASE STUDY: TILAPIA FISH IN MUSI RAWAS DISTRICT, SOUTH SUMATRA) Hertria Maharani
Widyariset Vol 18, No 1 (2015): Widyariset
Publisher : Pusbindiklat - LIPI

Fisheries industrialization announced by the Ministry of Marine and Fisheries Affairs aims to increaseproduction, productivity, and value added of fishery products. However, increased production without increasingmarketingefforts will make less successful impact for the program. This research examines the aquaculture, market,channel marketing, and trading of tilapia from Musi Rawas, South Sumatra. Field studies were conducted inMarch–June 2012. Survey method was used as the main instrument of this study, with the help of questionnairesand in-depth interviews with key informants. Respondents consisted of farmers, collectors, traders, and policymakers related tilapia. Descriptive analysis was conducted for the method of analysis. Results of the study showedthat despite an increase in production experienced by farmers, commodities are marketed only to the local market.Farmers are still the price takers which means they cannot increase the bargaining power. The structure of farmersmarkets are perfectly competitive, while the structure is oligopsonistic merchant. So the prices at the level of farmersare controlling nature merchants. To improve the welfare of farmers aquaculture, should diminishing patronclient relationship and search for new marketing channels need to be done as the customer looking for a restaurantor doing marketing tilapia up to another area.

CYBER-FREEDOM’S DILEMMA: COUNTRY’S POINT OF VIEW Khanisa Khanisa
Widyariset Vol 16, No 1 (2013): Widyariset
Publisher : Pusbindiklat - LIPI

The usage of cyber world in any kind of field is growing larger as the expand of technology. There are inevitable shift to cyber world due to its ability to make a more effective communication, cross the geographical border, and create the feeling of freedom to do anything. Although, this phenomenon also brings questions in how far freedom can be exercised and can a country control the freedom of the cyber world. With descriptive method using secondary data, this paper will try to explain the dilemma and answer those questions using a country point of view. This study aiming to get an understanding about cyber freedom, the implication in international politics, and the acceptable country’s role in it.

TEKNIK PEMODELAN 3D CITRA SATELIT LAPAN TUBSAT DENGAN VIDEOGRAMMETRI (Studi Kasus: Gunung Semeru) Atriyon Julzarika
Widyariset Vol 13, No 2 (2010): Widyariset
Publisher : Pusbindiklat - LIPI

LAPAN TUBSAT imagery can be made in 3D model using Videogrammetry. These 3D model used stereo model concept, geodetic control network, and Kriging method. First, LAPAN TUBSAT imagery in the form of video wastaken in two photo which have 60% overlay to create a stereo model. It needs to correct geometrically these two photos. After making 3D model, then geodetic control network that has been made can get ground control points from SRTM30. Kriging method that was resulted from geodetic control network was useful for making 3D model. 3D model needs statistical tests, they are display (athwart profile) and also geo-statisticsl. Its vertical accuracy was 5–9 m for SRTM30 with range 26–35 m. The research result concluded that LAPAN TUBSAT 3D model was created by Videogrammetry.

SIMULASI OPTIMASI PENGUKURAN STATE OF CHARGE BATERAI DENGAN INTEGRAL OBSERVER Asep Nugroho; Estiko Rijanto
Widyariset Vol 17, No 3 (2014): Widyariset
Publisher : Pusbindiklat - LIPI

The accuracy of state of charge (SoC) measurement has been an important key in the design of Battery Management System (BMS). A SoC measurement can prevent the battery from both overcharged and undercharged condition. One of the conventional methods for SoC estimation is coloumb counting (CC). This method has a drawback regarding to the accumulation of error propagation. To improve the accuracy of CC method, the integral observer could be added. In our work charge-discharge data simulation generated by PSIM was used to test the Integral observer performance. This research used general lithium-ion battery. It was found that this approach could significantly correct the error from the numerical integral calculation and discrete data input. The error of CC method at 4000 sec was found to reach 25%; however the error propagation could be decreased up to less than <3% by Integral observer.

Widyariset Vol 12, No 1 (2009): Widyariset
Publisher : Pusbindiklat - LIPI

A model of 125I-phalerin was designed in this research. The work was started by designing phalerin based on available data and followed by minimizing energy at bond angles, i.e C4-05-C7-C8 (0 ) , C5-C7-C8-C9 (2),C3-014-C15-C20 (3) and C4-C3-014-C15 (4).This work was then continued with designing of 115l -phalerin. Both models were put in overlaid position, then they were characterized. Result showed that phalerin model has characteristic of bond angle with 1 z 3, 4= 40°, 40°, 320°, 280° respectively. Energy ofphalerin model was 18,7625 kkal/mol. "51-phalern has similarity conformation with phalerin and the RMS for bond length, bond angle 0.0091 a and 0.5039° respectively.
