The Demand for and the Puzzle of Indonesian Decentralization Policy Reform

Syarif Hidayata, aDepartment of Doctoral Political Science School Universitas Nasional, Jakarta, Indonesia, Email: asyarif.hidayat@civitas.unas.ac.id

This paper attempts to review the concept, policies, and some studies concerning the nature of decentralization in Indonesia. The aims are to cast light on the issues of why Indonesians think that decentralization is necessary, and to identify how the controversy between ideological vs. technical orientation has emerged since the independence. It is  believed that the introduction of decentralization and regional autonomy policies in the post-Suharto’s period reduced the regional government dissatisfaction with the central government. It has also opened the political space for citizen participation in the policymaking process, and in governing their communities. Indonesian must put decentralization on the right track to prevent the desire of central government “to bring the centralized power back in”. Pages 1 to 16

Reconsidering the Concept of Good Governance: A Theoretical Discourse

Syarif Hidayata, Irma Indrayanib, aDepartment of Doctoral Political Science School Universitas Nasional, Jakarta, Indonesia, bDepartment of International Relations Faculty of Social anda Political Science Universitas Nasional, Jakarta, Email: asyarif.hidayat@civitas.unas.ac.id, birma.indrayani@civitas.unas.ac.id

This paper attempts to scrutinize the strengths and weaknesses of the concept of good governance, then to further carry out a "conceptual reconstruction" of the most suitable kind of governance for developing countries in general. Indonesia will be the focus of this paper.  The authors argue that the existence of the current good governance concept and its practices were a part of a "tool" in guarding the international development agendas. As a result, the parameters that were derived also tend to be one size fits for all. It is therefore necessary to re-analyze the concept of good governance again to bring the "right" governance back in. The ability to adapt to the idea of management that are adjusted with the characteristics of the social, cultural, economic, and political characters of the community was the basic argumentation on the success of managing the state and society. In brief, the idea of governance proposed by the authors was based on, at least, four pillars; Development, Democracy, Socially Inclusive, and Cultural and Historical context (local content).

Yayat Suharyata, Ali Nurdinb, aIslamic University "45" (UNISMA) Bekasi, Indonesia, bUniversitas Islam Negeri Syarif Hidayatullah Jakarta, Indonesia, Email: ayayat_suharyat@unismabekasi.ac.id, bali.nurdin@uinjkt.ac.id

Each profession must have essential values in order to meet professional goals and demands. This study aims to map the professional potential of Islamic Education Teachers (IET) according to the standards of learning processes. As a result, this mapping can be useful for school organizers to make improvements when there are difficulties in implementing such a standard. The purpose of this study is to identify: (1) The steps taken by IET in formulating their lesson plans, (2) The techniques performed by IET in preparing and enriching their teaching materials, (3) The learning strategies applied by IET, and (4) The evaluation methods used by IET during and after the learning process. This research uses a qualitative approach. The data was collected through document analyses, observations, and interviews with teachers and principals from several high schools in Bekasi City, West Java. The data was analysed using the model of data analysis suggested by Milles and Huberman. The results of the research show the following issues. Firstly, the majority of IET who have already been certified to teach in Secondary Schools in Bekasi City have made their lesson plans for both inside and outside the classroom. However, the quality of their lesson plans cannot be accounted for academically. Secondly, overall, the techniques performed by the IET in preparing and enriching their teaching materials still requires special attention. This is due to the lack of habit and discipline in developing their teaching materials. Thirdly, there has been a change in the learning strategies applied by the IET. Previously, their teaching did not actively involve many students. In the new way, however, their teaching directly involves more students.  Finally, the evaluation methods used by the IET during and after the learning process are still not maximized. This is due to the fact that there are so many forms of assessment which have to be filled out by the IET in assessing their students. Pages 38 to 47

This paper discusses the underground economy, a form of economic activity whose definition is often not clear and overlaps with the concepts of informal economy and illegal economy. This paper discusses the differences between the concepts and describes perspectives related to the existence of an underground economy. One standpoint views underground economy as a manifestation of new economic activities in the context of production and trading, reorganizing  the current global economic situation. In this context, the underground economy is regarded as a new opportunity for economic freedom. However, there is also another perspective which assumes that the underground economy is a form of deindustrialization and social exclusion, which can be described as a decrease of social and individual freedom that influences social inequality and poverty. Marginalisation, exploitation, and vulnerability become important dimensions in the discussion on underground economy. This paper focuses on trade network of the textile and textile products sector in Indonesia. Pages 95 to 115

 Effective Combination of Phyllanthus Niruri Linn. and Metformin to Improve Insulin Resistance in Obese Rats

A S Kosnayania*, AK Hidayatb, Darmana Ec, I Riwantod, S Hadisaputroe, a,bSiliwangi University, Tasikmalaya, East Java, Indonesia, c,d,eDiponegoro University, Centre Java, Indonesia, Email: a*aisrikosnayani@unsil.ac.id

Obesity is always relevant to insulin resistance. Insulin resistance, if not treated, will develop into Diabetes Mellitus (DM) or Cardiovascular Disease (CVD). Insulin resistance cannot be cured but controlled, through the management of obesity, with non-pharmacological or pharmacological approaches, such as using metformin. Metformin can reduce weight, blood glucose, and improve the lipid profile. However, it still has the disadvantage of indigestion and decreases the absorption of vitamin B12. Therefore, it is necessary to find an alternative form of herbal medicine. Phyllanthus niruri Linn. is known for being a hypoglycaemic, hypotensive, antioxidant that can control weight. This study aims to determine the effect of combination extracts of P. niruri, and metformin to improve insulin resistance in obese rats. The effect of repeated administration of a combination water extract of P. niruri 400 mg/kg BW and metformin 45 mg/kg BW was evaluated in obese Sprague Dawley rats and the placebo group. The indicators measured were Lee Obesity Index, fasting blood glucose, insulin, and insulin resistance. They were measured pre, after seven days, 14 days, 21 days and 28 days. A combination water extract of P. niruri, can give the effect of a lower Lee Obesity Index and differ from the control group (placebo) (p>0.05), lower blood glucose levels, insulin and insulin resistance (Homa_IR) with different effects (p<0.05). It was concluded that the combination water extract of P. niruri and metformin was effective to improve insulin resistance in obese rats. Pages 167 to 176

N Ratnaningsiha, E Hidayatb, S Santikac, a,b,cUniversitas Siliwangi, Jl. Siliwangi No. 24 Tasikmalaya, Indonesia, Email: ananiratnaningsih@unsil.ac.id

This study applies creative problem-solving learning to explore problem-solving skills and learning styles, which are important skills to train students. The purpose of this study is to analyse and describe the students' mathematical problem-solving skills and Kolb learning styles. The research method used is descriptive qualitative. The research subjects are 10th grade middle-class students in Tasikmalaya, Indonesia. Data collection techniques were applied through mathematical problem-solving tests, learning style questionnaires, and interviews. Based on the data analysis, it was concluded that the type of learning style of students through creative problem-solving learning consists of divergent, assimilation, convergence, and accommodation. Students' whose learning styles were divergent or assimilation, enabled them to understand problems, plan problem-solving strategies, and perform calculations correctly. While students with convergent and accommodation type learning styles were capable of recognising problems, and planning problem-solving strategies, but were less able to perform the calculations correctly. Students of divergent, assimilation, convergence, and accommodation types, are less able to look back on the truth of the answers in a different way. Thus, divergent and assimilation-type students are better at solving mathematical problems. Pages 177 to 186

Spatial ability has received less attention in learning, whereas it is well known that spatial ability makes it easier for students to understand science. This research aims to determine the role of 3D media on cognitive learning outcomes and reasoning for prospective biology teacher candidates by using the Wimba learning model. The Wimba learning model is a visuospatial-based learning model for enhancing spatial abilities. Research on the role of traditional media playdough (PD) and modern media with 3Ds Max software on learning outcomes and logical reasoning has been observed. The research was conducted by using a descriptive quantitative method and applying it to different learning outcomes on treatment with PD and 3Ds Max media. This was undertaken with two classes of Biology students during semester four, amounting to 56 students who took the course of plant anatomy. The first class was evaluated with PD media, while the second class was evaluated with 3Ds Max media. The results of the research based on PD showed improved learning outcomes with low categories, while logical reasoning can develop proportional variables and enhanced control variables. The results of the research based on 3Ds Max showed an improvement of learning outcomes with the medium category, and that logical reasoning can develop better on correlational and combinatorial variables and is able to improve student intellectual development. It was concluded that 3Ds Max media plays a better role in cognitive learning outcomes and reasoning. Pages 187 to 196

English for academic purposes (EAP), as a study skill, is a requirement for students at the university level in sustaining their academic competencies. However, the question of how best to teach the EAP course is largely overlooked, including the application of ICT as the learning media. The current study explores the challenges of pedagogy and the application of ICT in applying the EAP course, taken from English teachers’ perspective. The descriptive inquiry was used in identifying data. Observation and interview were undertaken to explore the multiple realities condition involving the thematic analysis used. The students’ survey was done to strengthen the collected data. The findings show that (1) needs analysis has not been implemented according to the ESP approach; (2) teacher’s difficulties in syllabus and course design are due to the large size of the EAP class and a lack of know-how in designing the effective EAP course; (3) material writing is a slight problem for the teachers due to a lack of knowledge, self-confidence, creativity, imagination and experience related with the students’ discipline in study; (4) the implemented evaluation is only focused on a paper and pencil test; 5) teachers had a strong desire to use ICT in applying the EAP course, but they encountered several barriers, like insufficient technical support and limited access to the internet. These are also considered as the major barriers preventing teachers from integrating ICT into the EAP class. In addition, the teachers have not maximised all the learning components and media in the implementation of the EAP course. EAP teachers have an important role in achieving the EAP learning goal. Teachers’ competencies should be upgraded and stakeholders’ support is required, including in providing suitable facilities in supporting the learning process. Pages 197 to 213

The ecology zone of southern West Java is dominated by dryland with a high level in slope, therefore it is vulnerable towards extreme climate change. The mismanagement of the ecology zone could create a negative impact on the social, economic, and environmental condition. The Polyculture Planation Model (PPM) is agreed as the conducive farming model to lead environmental protection and the improvement of dryland. The question remains as to whether the PPM model is conducive towards the farmer’s economic and social-culture sustainability. This research intended to analyse the sustainability and influence factors of the PPM. The research was conducted in the District Tasikmalaya, West Java, and was designed quantitatively using the survey method. The primary data was randomised from 250 farmers and collected via a questionnaire. The data was then analysed both descriptively and with inferential statistics using PLS. The secondary data was collected from an institution and literature study.  The result showed that the PPM positively influenced environmental sustainability, contributed to economic sustainability and constructed on social sustainability. The capitals of agricultural potential and multifunction influenced the PPM sustainability either partially or simultaneously. The increasing creation added value of the multifunction product and the PPM agent regeneration is needed in order to suite between social, economic, and environmental aspects of PPM.
