    Abstract: The rise of immodesty among the young people towards the elderly implies the lack of cultural identity. This behavior is not only performed by individuals within the family environment but also the entire aspects of the educational environment and society. Dealing with this condition, it is necessary to re-actualize the social norms as local wisdom for future generations like Gayo community. Here are the norms to avoid violating actions. These rules are used as a foundation of life called Sumang. This paper focuses on the concepts of Gayo community norms within the framework of Islamic education. This research employed a descriptive qualitative using field research method. The sampling technique was purposive sampling by selecting the research participants consisting of the prominent tribal leader of Gayonese people. The data were collected by using observation and semi-structured interview. Then, the data were documented and analyzed through data reduction, display, and conclusion. The purpose of this paper is to explore the heritage value of Gayo community that can be used as a reference to respond to the challenges of future generations. The findings showed that the Gayo norms managing social interaction known as Sumang (taboo) consisting of Sumang Kenunulen (sitting), Sumang perceraken (talking), Sumang pelangkahan (journey), Sumang penengonen (seeing). Those concepts in Gayo community norms within the framework of Islamic education are to prevent a contradiction to the religion and the cultural values or it can be classified as disrespectful attitudes. These norms have also been the foundation for developing character education.الملخص: يتزايد انتشار الخلافة بين الصغار والكبار بشكل متزايد ، مما يعني نقصًا في الأخلاق. هذا السلوك لا يتم فقط من قبل الأفراد في محيط الأسرة ولكن في جميع جوانب البيئة التعليمية وحتى المجتمع. لمعالجة هذا ، من الضروري الحفاظ على جدول الأعمال أو إعادة تفعيل المعايير الاجتماعية التي أصبحت حكمة محلية لأجيال. كما هو الحال في مجتمع Gayo ، لديها قواعد السلوك أو السلوك التي يجب تجنبها لخرق القيم. تستخدم القاعدة كنمط أساسي أو أساس للحياة يسمى سومانغ. تستعرض هذه الورقة معايير مجتمع Gayo ومفاهيم معايير مجتمع Gayo في إطار التعليم الإسلامي. تستخدم طريقة البحث هذه النوعية الوصفية ، مع البحث الميداني. استخدم المشاركون في هذه الورقة تقنية أخذ عينات هادفة ، وهي الشكل التقليدي لمجتمع جايو. طرق جمع ملاحظات البيانات ، ومقابلات الفصول ، والتوثيق أثناء تحليل البيانات باستخدام تقليل البيانات ، وعرض البيانات والاستنتاجات .الغرض من هذه الورقة هو استكشاف القيمة التراثية لمجتمع غايو ويمكن استخدامه كمرجع في الرد على تحديات الأجيال التي تفتقر إلى الأخلاق. تشير النتائج في هذا المجال إلى أن قواعد جايو التي تحكم التفاعل الاجتماعي تُعرف باسم سومانج كينونولن (المتنافرة عند الجلوس) ، ووسانجانج بيرسيكاكن (المتناقض في قول الكلمات) ، والسومانج بيلانجكان (المتناقض في السفر) ، وسومانج بيننغونين (طرق متضاربة للرؤية) ، إن مفهوم معايير مجتمع جايو في إطار التربية الإسلامية هو فعل يتعارض مع الدين ، لأنه يصنف كموقف غير جدير بالثناء وله تأثير غير موات ، ويمكن أن يكون هذا الأساس أساسًا لقيم الشخصية المتنامية.Abstrak: Maraknya sikap ketidaksopanan antara yang muda terhadap yang tua semakin merambah sehingga mensiratkan minimnya etika. Tingkah laku tersebut bukan hanya dilakukan individu di lingkungan keluarga, namun pada seluruh aspek lingkungan pendidikan bahkan masyarakat. Untuk menyikapi hal tersebut, perlu agenda pelestarian atau mengaktualisasikan kembali norma-norma sosial yang sudah menjadi kebijaksaan lokal secara turun temurun. Sebagaimana pada masyarakat Gayo, mempunyai aturan perbuatan atau tingkah laku yang harus dijauhi karena melanggar nilai. Aturan tersebut dijadikan pola dasar atau landasan hidup yang disebut Sumang. Tujuan tulisan ini untuk menggali nilai pusaka masyarakat Gayo dan dapat dijadikan acuan dalam menjawab tantangan generasi yang minim moralitas. Metode penelitian ini menggunakan deskriptif kualitatif, dengan penelitian lapangan (field research) serta partisipan menggunakan teknik purposive sampling,yaitu tokoh adat masyarakat Gayo. Pengumpulan data menggunakan pengamatan, wawancara semiterstruktur, dokumentasi, sedangkan analisa data menggunakan data reduction, displaydata serta kesimpulan. Temuan di lapangan bahwa norma masyarakat Gayo yang mengatur tata pergaulan dalam berinteraksi dikenal dengan istilah sumang kenunulen (sumbang ketika duduk), sumang perceraken (sumbang dalam mengucapkan kata-kata), sumang pelangkahen (sumbang dalam perjalanan), sumang penengonen (sumbang cara melihat). Konsep norma-norma masyarakat Gayo dalam bingkai pendidikan Islam merupakan tindakan yang bertentangan dengan adat, agama karena tergolong sikap yang tidak terpuji dan berdampak tidak baik. Norma tersebut juga telah menjadi dasar untuk menumbuhkan nilai-nilai karakter

    In 2010, an explosion occurred in the Macondo well in the Gulf of Mexico (GoM) that caused the oil rig to sink to the bottom of the ocean. At that time, there was no accurate method to estimate the flow rate of the hydrocarbon leakage. Timothy J. Crone used a noninvasive flow measurement technique, optical plume velocimetry to determine the flow rate using image analysis. There are several methods to estimate the flow rate measurement namely temporal cross correlation, frequency domain cross correlation, average square difference function, ASDF and average magnitude difference function, AMDF. The most important parameter in these methods is the time delay. However, Crone neglected the frequency domain cross correlation which may give a better flow rate estimation. The main motivation of this research is to do a comparative analysis of the four cross correlation algorithm as mentioned above. The four algorithms were used to estimate the flow rate where five simulations with five different flow rates were measured in order to determine the accuracy of each algorithm. Crone’s experimental setup was replicated and a DSLR camera was used to record the flow

    Penjatuhan Sanksi Pidana Maksimum Terhadap Pelaku Tindak Pidana Perkosaan Dihubungkan Dengan Pemenuhan Keadilan Korban

    Get PDF
    ABSTRAKArticle 285 of the Criminal Code states that anyone with violence and threats of violence forces a woman to have sex with him outside of marriage, is threatened with rape with a maximum imprisonment of twelve years. If you look at the written sanctions formulation, the maximum sentence for the crime of rape is twelve years. However, in reality, judges rarely impose maximum criminal sanctions in society as stated in these provisions. In addition, when viewed from the perspective of creating justice for victims of maximum criminal sanctions, it has not touched the recovery of losses and suffering experienced by rape victims. This research is a normative juridical research but is also supported by empirical data so that what is studied is data originating from the literature and court decisions. The results of the study indicate that the imposition of maximum criminal sanctions on perpetrators of the crime of rape as regulated in the Criminal Code has not been implemented properly, this is because in practice law enforcement officers including the panel of judges who should be the mouthpiece of justice have not been able to provide maximum sanctions. to the perpetrator, in imposing criminal sanctions the judge tends to ignore the condition of the victim who is traumatized and depressed. This provides clear evidence that there is still a lack of guarantees for legal protection for victims of sexual violence and rape in criminal justice in Indonesia.Pasal 285 KUHP menyatakan barang siapa dengan kekerasan dan ancaman kekerasan memaksa seorang wanita bersetubuh dengan dia di luar pernikahan, diancam karena melakukan perkosaan dengan pidana penjara paling lama dua belas tahun. Jika melihat formulasi sanski yang ditertulis maka pidana maksimum bagi tindak pidana perkosaan adalah dua belas tahun. Namum dalam kenyataannya di dalam masyarakat Hakim jarang menjatuhkan sanksi pidana maksimal seperti yang tercantum di dalam ketentuan tersebut. Selain itu apabila ditinjau dari terciptanya keadilan bagi korban sanksi pidana maksimum belumlah menyentuh pemulihan kerugian dan penderitaan yang dialami oleh korban perkosaan. Penelitian ini merupakan penelitian yuridis normatif namun juga didukung dengan data empiris sehingga yang diteliti adalah data yang berasal dari kepustakaan dan putusan pengadilan. Hasil penelitian menunjukkan bahwa penjatuhan sanksi pidana maksimum terhadap pelaku tindak pidana perkosaan sebagaimana diatur dalam Kitab Undang-Undang Pidana belum terimplementasi dengan baik, hal tersebut dikarenakan dalam prakteknya aparat penegak hukum termasuk didalamnya majelis hakim yang seharusnya menjadi corong keadilan ternyata belum mampu memberikan sanksi yang maksimal kepada pelaku, dalam penjatuhan sanksi pidana hakim cenderung mengabaikan kondisi korban yang mengalami trauma dan depresi. Hal tersebut memberikan bukti nyata bahwa masih minimnya jaminan perlindungan hukum terhadap korban kekerasan seksual perkosaan dalam peradilan pidana di Indonesia
