Institutionalization of the Approval Principle of Majority Creditors for Bankruptcy Decisions in Bankruptcy Act Reform Efforts

Abstract: This study aims to determine the urgency of institutionalizing the principle of bankruptcy decisions that must be approved by the majority creditors with a test stone in the form of a bankruptcy decision Number: 04/Pdt.Sus-PKPU/2018/PN.Niaga.Jkt.Pst then also to analyze the opportunities for institutionalizing the principle. mentioned in Indonesian law. This research is a normative legal research with an approach in the form of a conceptual approach, and a statute approach and a case approach. The results show that the urgency of applying the principle of "Approval of Bankruptcy Decisions Must be approved by Majority Creditors" in Indonesia is based on the Bankruptcy Decision Number: 04/Pdt.Sus-PKPU/2018/PN.Niaga.Jkt.Pst, in addition to following the development of global bankruptcy law. , also in order to provide justice to fellow creditors so that no creditor feels aggrieved in any future bankruptcy decisions. The principle itself requires that each bankruptcy decision be approved by at least 50% of the majority of creditors according to the number of claims (receivables), not the majority according to the number of people. Even though, the application for a bankruptcy statement was made by the Debtor himself, the bankruptcy decision should not have been taken by the court without the approval of the creditors or the majority of creditors. Also, the opportunity to apply this principle in Indonesia is very possible considering that the principle is in accordance with the character of the nation which clearly makes consensus & deliberation as an alternative in every problem that exists within the Indonesian nation, it is not wrong if this is also applied in the concept of the Bankruptcy Law in the future (das sein).

The development of students worksheet based on Predict, Observe, Explain (POE) to improve students’ science process skill in SMA Muhammadiyah Imogiri

Abstract: This study aims to: 1) obtain the appropriate product of physics Worksheet based on POE, 2) determine the students' performance using POE-based Worksheet to improve the scientific process skill. This research is Research and Development (R & D). The development conducted by referring to the 4-D model (Define, Design, Develop and Disseminate). The subject of this study is the students of SMA Muhammadiyah Imogiri Yogyakarta. The total number of students is 42, 10 students belong to the small group test, 32 students belong to field test. The instruments of the research a questionnaire, test (post-test), and the distribution of student responses on the Worksheet. The results of this study were 1) the development results of physics POE-based Worksheet was feasible by the experts validation based on the content, language, presentation, and good validity graphic; 2) the percentage of learners' success in implementing the skills of the scientific process in the formulating hypotheses (83.1%), choose tools and materials (83.1%), writing experimental data (68.8%), analysing data (72.1%), interpreting data (77.1%) and make conclusions (91.4%). Based on the percentage of students achievement, the result on pre-test 36.5% (not good) and post-test 72.0% (quite good), the results able to be calculated the improvement of students' achievement competencies using N -Gain technique 0.6 which included in the middle category. Based on this result, the developed Worksheet had a decent usage.

Effect of Massage on Sleep Quality and Motor Development in Infant Aged 3-6 Months

Abstract: Background: In theory, infant massage is beneficial for improving sleep quality, gross and fine motor development. Infants aged 3-6 months are able to receive stimulation that may help develop gross and fine motor development. Massage may improve brain function and raise the release of growth hormone, and strengthen muscle. This study aimed to determine of the effect of massage on sleep quality, gross and fine motor development among infant aged 3-6 months. Subject and Method: This was a randomized controlled trial, conducted in Magelang, Central Java, from 1 August to 16 September 2016. A total of 60 infants in Azza Momby Spa, Magelang was selected for this study by simple random sampling. This sample was then allocated at random into massage group (n1=30) and control group (n2=30). The independent variable was infant massage. The dependent variables were sleep quality, gross and fine motor development. The data was collected by using questionnaire. The difference of dependent variables between the two groups were tested by Mann-Whitney. Results: After intervention, infants in the massage group (median=2.00; SD=1.80) slept better than the control group (median=0.00; SD=0.95), and it was statistically significant (p<0.001). Infants in the massage group (median=0.00; SD=0.81) had better gross motor development than the control group (median=0.00; SD=0.72), and it was statistically significant (p=0.043). Infants in the massage group (median=0.00; SD=0.81) had better fine motor development than in the control group (median=0.00; SD=0.48), and it was statistically significant (p=0.018). Conclusion: Massage is effective to improve sleep quality, gross and fine motor development, in infants aged 3-6 months. Keywords: massage, sleep quality, gross and fine motor development, infant Correspondence: Nurry Ayuningtyas Kusumastuti. Masters Program in Public Health, Sebelas Maret University, Surakarta.

A review porosity in aluminum welding

Abstract: Aluminum is a material that is often used in the transportation industry because it has a low density, high strength, and good corrosion resistance. The transport structure requires connection to achieve a form as designed. The joint process usually uses a welding process because welding has good metallurgical properties, superior mechanical properties, and low cost. Aluminum welding generally has disadvantages. One of these weaknesses is the formation of porosity, which will affect the welded joint’s mechanical properties, so the discussion of porosity in aluminum welded joints is critical. This paper attempts to provide an overview of the formation mechanisms and types of porosity defects in aluminum alloys’ welding method. A brief description of the effect of the environment on porosity defects, the causes of porosity formation, the impact of porosity, and how to reduce porosity in aluminum welding will be discussed. In conclusion, the formation of porosity in the welding process is due to dissolved hydrogen in the weld metal, air/bubbles from the welding process, filler/filler wire, and the environment welding influence. The impact of porosity can cause cracks in welded joints, decreased ductility, and failure of fatigue. This study’s results can be used as a basis for analyzing the relationship between the welding environmental parameters and the welding defect porosity.
