UPAYA GURU DALAM MENGATASI KESULITAN BELAJAR SISWA

ABSTRAK  Untuk mencapai kondisi belajar yang optimal itu, maka guru memerlukan keterampilan khusus untuk mengelola kelas yaitu keterampilan untuk menciptakan dan memelihara kondisi kelas yang optimal, apabila terdapat gangguan dalam proses belajar mengajar, tugas guru merencanakan dan melaksanakan proses pembelajaran, menilai hasil pembelajaran, melakukan pembimbingan dan pelatihan serta melakukan penelitian dan pengapdian kepada masyarakat. Hasil penelitiannya, guru sebagai  pendidik, dalam hal ini upaya yang dilakukan oleh guru MTs Darussalam Ngentrong Kecamatan Campurdarat Kabupaten Tulungagung adalah dengan menggunakan berbagai bentuk media pembelajaran, yaitu media audio, media visual dan media audio visual, menggunakan metode beragam, dan memberikan motivasi kepada siswa. Guru sebagai  pembimbing, pengawasan yang dilakukan oleh para guru di MTs Darussalam Ngentrong Kecamatan Campurdarat Kabupaten Tulungagung adalah dengan cara dua bentuk, yaitu dengan  melakukan  pengarahan dan monitoring tingkah laku siswa, dan bagi para siswa yang membandel serta melanggar peraturan sekolah, diberikan bimbingan dengan hukuman. Guru sebagai penilai, penilaian yang dilakukan guru di MTs Darussalam  Ngentrong  adalah  menggunakan  penerapan berbagai cara dan  penggunaan beragam alat penilaian untuk memperoleh informasi tentang sejauh mana hasil belajar peserta didik atau ketercapaian peserta didik. Hasil penilaian berupa nilai kualitatif dan nilai kuantitatif.  Kata Kunci      : Guru dan Kesulitan Belajar &nbsp

Number relation in the Qur’an

This article aims to find out the forms of number relations contained in the Qur'an. The method used is library research or a library approach through writings in books and journal articles. The results of this study are known that there are editors of verses in the Qur'an that contain mathematical number relations such as equal to (=), less than (), more than or equal to (≥) and not equal to (≠)

Dielectric relaxation dynamics of high-temperature piezoelectric polyimide copolymers

Polyimide co-polymers have been prepared based on different diamines as co-monomers: a diamine without CN groups and a novel synthesized diamine with two CN groups prepared by polycondensation reaction followed by thermal cyclodehydration. Dielectric spectroscopy measurements were performed and the dielectric complex function, ac conductivity and electric modulus of the co-polymers were investigated as a function of CN group content in the frequency range from 0.1 Hz to 107 Hz at temperatures from 25 to 260 °C. For all samples and temperatures above 150ºC, the dielectric constant increases with increasing temperature due to increaseing conductivity. The α-relaxation is just detected for the sample without CN groups, being this relaxation overlapped by the electrical conductivity contributions in the remaining samples. For the copolymer samples and the polymer with CN groups an important Maxwell-Wagner-Sillars contribution is detected. The mechanisms responsible for the dielectric relaxation, conduction process and electric modulus response have been discussed as a function of the CN groups content present in the samples.This work was supported by FEDER through the COMPETE Program and by the Portuguese Foundation for Science and Technology (FCT) in the framework of the Strategic Project PESTC/FIS/UI607/2011 and grants SFRH/BD/ 62507/2009 (A.C.L.)

Applications of lignin in the agri-food industry

Of late, valorization of agri-food industrial by-products and their sustainable utilization is gaining much contemplation world-over. Globally, 'Zero Waste Concept' is promoted with main emphasis laid towards generation of minimal wastes and maximal utilization of plantbased agri-food raw materials. One of the wastes/by-products in the agri-food industry are the lignin, which occurs as lignocellulosic biomass. This biomass is deliberated to be an environmental pollutant as they offer resistance to natural biodegradation. Safe disposal of this biomass is often considered a major challenge, especially in low-income countries. Hence, the application of modern technologies to effectively reduce these types of wastes and maximize their potential use/applications is vital in the present day scenario. Nevertheless, in some of the high-income countries, attempts have been made to efficiently utilize lignin as a source of fuel, as a raw material in the paper industry, as a filler material in biopolymer based packaging and for producing bioethanol. However, as of today, agri-food industrial applications remains significantly underexplored. Chemically, lignin is heterogeneous, bio-polymeric, polyphenolic compound, which is present naturally in plants, providing mechanical strength and rigidity. Reports are available wherein purified lignin is established to possess therapeutic values; and are rich in antioxidant, anti-microbial, anti-carcinogenic, antidiabetic properties, etc. This chapter is divided into four sub-categories focusing on various technological aspects related to isolation and characterization of lignin; established uses of lignin; proved bioactivities and therapeutic potentials of lignin, and finally on identifying the existing research gaps followed by future recommendations for potential use from agri-food industrial wastes.Theme of this chapter is based on our ongoing project- Valortech, which has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No 810630
