Analysis and evaluation of uncertainty for conducted and radiated emissions tests
Whenever an EMC measurement is made, there are numerous uncertainties in different
parts of the measurement system and even in the EMC performance of the equipment
under test (EUT) which is being measured. It is important to be able to estimate the
overall uncertainty, in particular, the test setup and measurement equipment uncertainty.
However, making repetitive measurements can reduce the measurement uncertainty, but
often economics of time do not permit that. Therefore, a practical process, which is used
to evaluate uncertainty in EMC measurement a, according to the principle of uncertainty
and conditions in EMC measurement is presented. In this study, an efficient analysis of
uncertainty for both radiated and conducted emissions tests is performed. The
uncertainty of each contributor had been calculated and evaluating the reported
expanded uncertainty of measurement is stated as the standard uncertainty of
measurement. This standard uncertainty is multiplied by the coverage factor k=2, which
for a normal distribution corresponds to a coverage probability of approximately 95%.
The result of calculating the uncertainty for both conducted and radiated emission tests
showed that the overall uncertainty of the system is high and it must be lowered by
reducing the expanded uncertainty for the dominant contributors for both tests. In
addition, the result of applying the concept of CISPR uncertainty for both conducted and
radiated emission tests showed that non-compliance is deemed to occur for both EUT of
both tests. This is due to the result that the measured disturbances increased by
(
), above the disturbance limit
Keefektifan Model Pembelajaran Realistik dalam Seting Kooperatif ditinjau dari Sikap, Motivasi, dan Kemampuan Berpikir Kritis Matematis Siswa SMP
Penelitian ini bertujuan untuk mendeskripsikan keefektifan model pembelajaran Realistik dalam Seting Kooperatif (RESIK) ditinjau dari sikap terhadap matematika, motivasi belajar matematika, dan kemampuan berpikir kritis matematis siswa SMP.
Penelitian ini adalah penelitian eksperimen semu dengan pretest-postest non equivalent group design. Penelitian ini menggunakan satu kelompok eksperimen dan satu kelompok kontrol. Populasi penelitian mencakup seluruh siswa kelas VII SMPN 1 Selong yang terdiri dari 6 kelas. Dari populasi penelitian yang ada diambil secara acak dua kelas yaitu kelas VIIB dan kelas VIIC sebagai sampel penelitian. Pembelajaran matematika pada kelas VIIB menggunakan model pembelajaran RESIK sedangkan pembelajaran matematika pada kelas VIIC menggunakan model konvensional. Instrumen yang digunakan untuk mengumpulkan data adalah tes kemampuan berpikir kritis matematis, angket sikap terhadap matematika, dan angket motivasi belajar matematika. Pemberian bukti validitas instrumen menggunakan validitas isi dan validitas konstruk, sedangkan mengestimasi reliabilitas menggunakan Alpha Cronbach. Untuk menguji keefektifan model pembelajaran RESIK dan model konvensional ditinjau dari masing-masing aspek yaitu sikap terhadap matematika, motivasi belajar matematika, dan kemampuan berpikir kritis matematis digunakan analisis one sample t-test pada taraf signifikansi 5 %. Selanjutnya untuk membandingkan keefektifan model pembelajaran RESIK dan model konvensional ditinjau dari aspek sikap terhadap matematika, motivasi belajar matematika, dan kemampuan berpikir kritis matematis data dianalisis dengan menggunakan uji T2 Hotteling dengan taraf signifikansi 5 %, dan uji-t univariat untuk menentukan model manakah yang lebih efektif.
Hasil penelitian menunjukkan bahwa penerapan model pembelajaran RESIK efektif ditinjau dari sikap terhadap matematika, motivasi belajar matematika, dan kemampuan berpikir kritis matematis siswa. model pembelajaran RESIK lebih efektif daripada model konvensional ditinjau dari sikap terhadap matematika, motivasi belajar matematika, dan kemampuan berpikir kritis matematis

PERAN TOKOH AGAMA DALAM MENANAMKAN KARAKTER KEISLAMAN REMAJA DI DESA TOLOUWI
Penelitian ini tujuannya adalah, a) untuk mengetahui peran tokoh agama dalam menannamkan karakter keislaman remaja di desa tolouwi, b) untuk mengetahui apa sajakah faktor penghambat dan pendukung tokoh agama dalam menanamkan karakter keislaman remaja di desa tolouwi. Sumber data pada penelitian ini adalah data primer dan data sekunder. Pada penelitian ini data di kumpulkan dengan menggunakan metode pengamatan/observasi, metode interview/wawancara dengan tehnik dasar dan lanjut dengan metode dokumentasi.
Dari hasil penelitian ditemukan bahwa tokoh agama memiliki beberapa peran penting dalam kehidupan beragama yaitu : Peran kaderisasi yakni suatu cara untuk membina para remaja dalam suatu perkumpulan tertentu yang dibentuk dalam sebuah organisasi remaja agar kegiatan yang dilakukan lebih terarah dan memiliki tujuan yang jelas, seperti halnya organisasi remaja masjid dan organisasi komunitas pemuda hijrah, melakukan dakwah door to door yaitu melakukan dakwah dengan cara mendatangi warga masyarakat dari rumah ke rumah. Melakukan dakwah secara terbuka yaitu dengan cara mengisi kegiatan keagaman seperti kegiatan hari-hari besar Islam, ta’jiah kematian, ceramah, kultum, khutbah jumat dan mengisi kegiatan majelis ta’lim. Faktor penghambat dan pendukung peran tokoh agama dalam menanamkan karakter keislaman remaja faktor penghambatnya yaitu: rendahnya pendidikan keagamaan orang tua, kesenjangan social, kurangnya kerja sama antar tokoh agama dan pemerintah stempat yang masih kurang baik. Adapun faktor pendukungnya yaitu keaktifan tokoh agama dalam memberikan pengarahan keagamaan terhadap masyarakat terhusus para remaja, adanya dukungan dari orang tua walaupun sebagian orang tua masih banyak yang belum paham tentang hal keagamaan sehingga proses pendidikan akhlak berjalan kurang baik

Türkiye'nin Somali'de Bir Güvenlik Aktörü Olarak Artan Rolü: Dinamikler ve Motivasyonlar
Somalia has a special place in the foreign policy of the Justice and Development Party (AK Party), which has
been in power since 2002. Turkey's relations with Somalia began to develop after the official visit of Turkish
President Recep Tayyip Erdogan to Somalia on 19 August 2011, who was the prime minister at that time, to
support Somalis affected by severe drought and civil war. After 2011, Turkey launched one of the largest
humanitarian aid campaigns to Somalia. Turkey has not only developed a soft power policy in Somalia but
also started to implement a hard power policy. In this respect, Turkey has been training hundreds of Somali
soldiers and police in both Ankara and Mogadishu since 2012. At the same time, Turkey opened its largest
military base abroad in Somalia in 2017. This research explores the reasons and dynamics behind Turkey's
deepening of its security policy in Somalia and sheds light on what Turkey's security policy means for
Somalia. The research argues that there is a combination of factors driving Turkey's security policy towards
Somalia, including socio-cultural, economic, and geopolitical. This study examines Turkey's security policy
with a holistic approach, using conceptual and theoretical perspectives.2002 yılında iktidara gelen Adalet ve Kalkınma Partisi'nin (AK Parti) dış politikasında Somali'nin özel bir
yeri bulunmaktadır. Türkiye'nin Somali ile ilişkileri, dönemin başbakanı olan Türkiye Cumhurbaşkanı
Recep Tayyip Erdoğan'ın 19 Ağustos 2011 yılında şiddetli kuraklıktan ve iç savaştan etkilenen Somalilere
destek olmak amacı ile bu ülkeye düzenlediği resmi ziyaretin ardından gelişmeye başlamıştır. 2011'den
sonra Türkiye, Somali'ye en büyük insani yardım kampanyalarından birini başlatmıştır. Türkiye, Somali'de
sadece bir yumuşak güç politikası geliştirmekle kalmamış, aynı zamanda bir sert güç politikası da
uygulamaya başlamıştır. Bu kapsamda Türkiye, 2012 yılından bu yana hem Ankara’da hem de Mogadişu'da
yüzlerce Somalili asker ve polise eğitim vermektedır. Aynı zamanda Türkiye, 2017 yılında yurtdışındaki
Türkiye’nin en büyük askeri üssünü Somali'de açtı. Bu araştırma, Türkiye'nin Somali'de güvenlik
politikasını derinleştirmesinin ardındaki nedenleri ve dinamikleri incelemekte ve Türkiye'nin güvenlik
politikasının Somali için ne anlama geldiğini tartışmaktadır. Araştırma, sosyo-kültürel, ekonomik ve
jeopolitik dahil olmak üzere Türkiye'nin Somali'ye yönelik güvenlik politikasını yönlendiren faktörlerin bir
kombinasyonu olduğunu savunuyor. Bu çalışma, kavramsal ve teorik perspektifler kullanarak Türkiye'nin
güvenlik politikasını bütüncül bir yaklaşımla incelemektedir
