TRUE SHALLOT ( Allium cepa var ascalonicum ) SEED PRODUCTION DURING OFF SEASON

The application of seed for true shallot cultivation is an alternative of the more common cultivation practice, in which 30% of harvested tubers used for cultivation purposes. The seed production of this temperate tuber, in the tropical region, is quite challenging due to low flowers and seed formation. Several studies showed that vernalization (cold induction) and application of Benzil Amino Purin (BAP) could be applied to improve flowering and seed production. However, such studies were conducted during the best cultivation period for about 3 months and thus, limit the production period of seeds. This study was conducted to observe the effect of both methods outside cultivation periods to flower and capsule numbers, fruit set, and weight of 100 seeds compared with common cultivation. In this study, bulbs of onion vernalized at 10oC for 30 days then became subjected to synthetic hormone (BAP) prior planted while control group The results showed that BAP treated shallot group has the lowest values for all observed parameters (1552.67, 312.11, 22.5%, 0.2244 gram) compared to those vernalization treated group (1592.44, 623, 30.5%; 0.2261 gram) and control group (6774.67; 3898.44; 57.06%; 0.3304 gram). Based on this study, it could be concluded that common cultivation is a better method to produce true shallot seeds during the offseason

Dengan metode pelatihan meliputi teori danpraktik, para peserta diberikan pengenalan komponen yang digunakan berikut cara mengujikerusakan komponen dengan menggunakan Multimeter. Untuk pembuatan lampu JouleThief setiap peserta diberi kesempatan membuat masing-masing 1 buah lampu denganmetoda meniru hasil yang sudah dirakit sebelumnya oleh tim pendamping. Dari pelatihanini dihasilkan lampu Joule Thief dengan daya 3 Watt (AC) yang dicatu dari batere 3 Voltseri AA sebanyak 20 buah yang dapat langsung dapat dimanfaatkan oleh para peserta,terutama ketika terjadi pemadaman aliran listrik di lingkungan panti

ENGAGING STAKEHOLDERS IN PARATRANSIT INDUSTRY Comparative Study on South Africa and Jakarta

The issue of BRT (Bus Rapid Transit) feeder is being intensively discussed in several big cities in Indonesia. Jakarta is trying to initiate the construction of this feeder, because Jakarta has more advanced BRT system than do the other cities. In addition, the growth of paratransit vehicles in Jakarta requires special treatment so that a clear management can be performed. The success of BRT in South Africa becomes a reference. There are 3 (three) things to note in the development, namely funding, commitment, and organization. Funding and commitment could work quickly because it coincided with the convening of the World Cup 2010, so the last point, namely organization, should be noticed. Many stakeholders get involved in organizational development of public transport industry, and must comply with the theory of stakeholder relationship and stakeholders� engagement. It needs proper management for operators, organization, and also Dishub as Public Transport Authority (PTA). This research discusses the success of South Africa in building engagement among stakeholders in their country, and how to apply it in Jakarta, based on the real experiences. For its application, it will take some theories and rules to be put into operation by the stakeholders, as a reference in achieving success

Estimation of children’s age based on dentition via panoramic radiography in Surabaya, Indonesia

Background: Age may be estimated using tooth eruption sequence and/or calcification stage. Because many factors may affect the time of eruption, the tooth calcification stage shows higher accuracy than the time of tooth eruption. Demirjian’s and Willems’ methods have been most commonly used for dental age estimation. Both Willems and Demirjian use the calcification stage as an indicator. Studies comparing these methods have shown varied results, as they have been performed on different populations. Purpose: This paper aims to analyse the estimation of children's age based on dentition via panoramic radiography in Surabaya, Indonesia. Methods: This is a cross-sectional study using a purposive sampling method. One hundred digital panoramic radiographs of children between 6 and 15 years that match the inclusion criteria from the Airlangga University dental hospital in Surabaya, Indonesia were evaluated. One researcher analysed estimated dental age (EDA) three times in a one-week time-lapse using Demirjian’s and Willems’ methods. Statistical analysis was carried out using a Paired t-test and Wilcoxon signed-rank test. EDA was calculated using both Demirjian’s and Willems’ methods. Results: The mean chronological age (CA) was 10.57 ± 2.70 for males and 10.73 ± 2.84 for females. The mean difference between CA and EDA using the Demirjian and Willems methods was -0.57 ± 1.17 and 0.10 ± 0.96 for males and 0.58 ± 1.40 and 0.44 ± 0.94 for females. Conclusion: The results suggest that Willems’ method is more precise than Demirjian’s method in males and females and more suitable for children in Surabaya, Indonesia
