This study focuses on developing the new level of scientific argumentation skills and new items that are feasible and valid for used. There are 195 science students at Islamic State School 1 (MAN 1) Yogyakarta as participant in this study. Random sampling technique was used from the three schools of Islamis State School (MAN) in Yogyakarta, Indonesia. There are seven experts (3 Professor, 2 teachers, and 2 graduate students) reviewed 14 items for the first phase of this study. For the second phase, 98 students answered 14 questions which each questions contain five point (claim, data, backing, warrant and rebuttal). For the third phase, after choosed the best five 5 questions, We asked the others (97 students) to answer those questions. The modification of the level of scientific argumentation skills indicates the ability of students is still low. At level 1 (claims) there were only 38.9% students, level 2 (data) were 21.6% students, level 3 (warrants) 16.6% students, level 4 (backing) 16.2% while level 5 (rebuttal) is the most difficult, for students’ users only by 4.2%. Based on the findings, the test can measure and show with a separate level of students' scientific argumentation skill in this school.

Due to inherent portability of laptops, users frequently assume inconvenient postures while using them that may lead to discomfort or injury. The study was conducted to evaluate the postures and identify the prevalence of musculoskeletal symptoms in girls using laptops for which 100 college going female students between 18 - 25 years age group were selected through random sampling technique. A self-structured questionnaire was used to assess the laptop usage among adolescents and Rapid Upper Limb Assessment (RULA) was used to assess the posture of students while working with laptop. Standardized Nordic Musculoskeletal Questionnaire (SMSQ) was used to assess the nature and severity of self-rated musculoskeletal symptoms. Results revealed that the maximum respondent’s (74%) posture came under Action level 3 and 26% respondents comes under Action level 2 which indicated that the posture needed “further investigation and may need change” or “changes needed soon”. There was a positive correlation in Normal (0.50), Mild (0.31), Moderate (0.56) and Severe users (0.60) between the posture adopted by the respondents and the incidence of pain in last 12 months and in Normal (0.76), Mild (0.52), Moderate (0.56) and Severe user (0.65) respectively in last 7 days. The Musculoskeletal Symptoms was prominent in various anatomic regions like Neck, Shoulders, Upper back and Lower back, respectively. These symptoms if not addressed at an earlier stage might lead to Musculoskeletal Disorders.

In a decision-making environment related to risk, there are four basic circumstances, namely certainty, risk, uncertainty and conflict. The dynamics of the strategic environment in Southeast Asia cannot be separated from the movement of the development of the Islamic State (IS). The terror threat in Southeast Asia is currently divided into different generations of terror, namely the threat of the Al-Qaeda terror network and the threat of the ISIS terror network. This study aims to analyze and identify the risk value of the development of the Islamic State network in Southeast Asia using the Borda and TOPSIS methods. The Borda method is used to give weight to the criteria related to risk analysis. The TOPSIS method is used to provide a criteria-based risk score. This research is limited to the Southeast Asia region with 4 (four) major countries, namely Indonesia, Malaysia, Thailand, and the Philippines. This research is expected to contribute to control the development of Islamic state networks in the Southeast Asian region. Based on the results of the overall risk analysis, it was found that the Philippines has the highest risk factor value for Islamic State (IS) with a value of 0.550 at level 4 in the High category. Indonesia maintains a risk factor value of 0.307. Thailand has a risk factor value of 0.427. Indonesia and Thailand are at level 3 with the Medium category. Meanwhile, Malaysia has a risk factor value of 0.203 at level 2 in the Low category.

Hutan rakyat tidak hanya menghasilkan kayu akan tetapi juga memberikan hasil hutan bukan kayu (HHBK), malah pada beberapa tempat HHBK ini menjadi primadona. Tujuan penelitian ini untuk mendapatkan data mengenai jumlah kontribusi pendapatan HHBK di hutan rakyat serta permasalahan dan keunggulan pengembangan HHBK. Kegiatan dilaksanakan di Desa Karyabakti Kecamatan Parungponteng Tasikmalaya, pada bulan Juni-Desember 2013. Obyek kajian adalah petani hutan rakyat yang dipilih secara stratified random sampling berdasarkan luas kepemilikan lahan hutan rakyat sebanyak 30 orang. Pengambilan data dilakukan dengan cara wawancara dengan menggunakan kuisioner. Selanjutnya data yang terkumpul dianalis secara statistik dan disajikan secara diskriptif. Hasil kajian menunjukkan bahwa rata-rata responden memiliki lahan seluas 0,374 ha dan paling luas diperuntukkan untuk usaha hutan rakyat yaitu 0,246 ha atau 65,78 %. Pola tanam yang dikembangkan adalah pola agroforestri yaitu percampuran antara tanaman kayu dan HHBK yang merupakan tanaman perkebunan, tanaman buah, tanaman obat dan tanaman pangan. Periode pendapatan dari tanaman HHBK ini adalah mingguan, bulanan dan tahunan. Kontribusi HHBK terhadap total pendapatan hutan rakyat adalah 67,56% (strata 1), 63,93 % (strata 2) dan 75,11 % (strata 3) sedangkan kontribusi tanaman kayu sebesar 32,44 % (strata I), 36,07 % (strata II) dan 24,89 % (strata III). Dengan demikian, kontribusi HHBK setiap tahunnya jauh lebih tinggi namun sayangnya pengembangan HHBK ini belum maksimal, padahal hasilnya masih dapat lebih ditingkatkan. Salah satu kendala pengembangan HHBK adalah aspek budidaya yang diterapkan masih belum sesuai dengan standar operasional prosedur (SOP) dari Kementerian Kehutanan. Untuk itu, maka perlu upaya peningkatan HHBK salah satunya dengan transfer pengetahuan dan teknologi melalui penyuluhan.Kata kunci: hutan rakyat, hasil kayu, HHBK, kontribusi, pendapatan The  contribution of  income from Non Timber Forest Product to the  agroforestry business in community forest in Tasikmalaya RegencyAbstractCommunity forests is not merely producing timbers, but also non timber forest products (NTFPs) which are even more important at several places. The objective of the research was to obtain the data with regard to the advantage of developing NTFPs from community forests and its contribution to income of farmer. This study was conducted at Karyamukti village, Parungponteng Sub-district, Tasikmalaya District from June to December 2013. Thirty forest farmers were selected by stratified random sampling technique based on the size of forest ownership. Questioners were used to support interviews during data collection activities. Collected data were statistically analyzed and presented descriptively. The result showed that respondents own land areas averagely 0.374 ha whereas 0.246 ha or 65.78 % of them were utilized for community forest business. The developed planting system was agroforestry i.e. mixing the timber plants with NTFP plants such as estate, fruity, medicinal, and food plants. The period income gained from NTFP could be weekly, monthly, and annually. Income contributions of NTFPs to total income from farm forest were 67.56 % (level 1), 63.93 % (level 2) and 75.11 % (level 3), while the income contributions of timbers were only 32.44 % (level 1), 36.07 % (level 2), and 24.89 % (level 3). The annual income contribution of NTFPs, therefore, was higher than the one from timbers. The contribution, actually, could be increased if the NTFPs were developed seriously. One constrain in the NTFPs development was the silviculture technique operated by farmers, which did not follow the standard operational procedure (SOP) issued by The Ministry of Agriculture. Based on that condition, efforts to improve NTFPs development by transferring the knowledge and technology through extension are urgently required.

The COEL database and database software, a combined reference and research tool created by historians for historians, is presented here through Screenshots illustrating the underlying theoretical model and the specific situation to which that has been applied. The key emphases are upon data integrity, and the historian's role in interpreting and manipulating what is often contentious data. From a corpus of sources (Level 1) certain core data are extracted for separate treatment at an interpretive level (Level 3), based upon a master list of the core data (Level 2). The core data are interdependent: each record in Level 2 is of interest in itself; and it either could or should be associated with an(other) record(s) as a specific entity. Sometimes the sources are ambiguous and the association is contentious, necessitating a probabilty-coding approach. The entities created by the association process can then be treated at a commentary level, introducing material external to the database, whether primary or secondary sources. A full discussion of the difficulties is provided within a synthesis of available information on the core data. Direct access to the source texts is only ever a mouse click away. Fully query able, COEL is formidable look-up and research tool for users of all levels, who remain free to exercise an alternative judgement on the associations of the core data. In principle, there is no limit on the type of text or core data that could be handled in such a system.

This article reports on a study that was carried out to establish determinants of ICT integration in mathematics teaching and learning. This paper focuses on the kind of support teachers require to effectively use ICT in teaching mathematics. An exploratory sequential mixed methods research design was employed to conduct this study in which quantitative data was initially collected in the first phase. Qualitative data was then collected in the second phase to explain the quantitative data collected in the initial phase. The study targeted all the teachers teaching in lower grades in both private and public schools. A sample size of 40 lower primary schools were purposively selected based on the availability of ICT tools for instructional purposes in those schools. Three teachers teaching in grade one, two and three were then selected using simple random sampling technique especially in cases where more than three teachers existed. Teacher Questionnaire, Teacher Interview Protocol and Observation Protocol were used to collect data. Data was analyzed qualitatively using descriptive phenomenological analysis in which data transcriptions were divided into themes and sub-themes related to phenomena under study. The findings of the study revealed that there was a significant relationship between supporting teachers’ use of ICT in the classroom and their actual use of ICT in teaching mathematics. The study findings however revealed that teachers teaching lower grades in Mombasa, Kenya were not adequately supported in their use of ICT in teaching mathematics. It was recommended that teachers must be granted adequate support in their use of ICT in teaching mathematics.
