Abstract

Each phase of age that the human being undergoes has special characteristics that distinguish it from other phases of growth. The purpose of this study was to find out how influential psychology education is on adolescent education. This research uses qualitative research methods, namely by utilizing sources from previous research and utilizing other sources that are library analysis as the main object of research. The results of this study are the most appropriate learning model in adolescent psychology when facing various problems that relate physical, cognitive, emotional and psychosocial. It takes the role of parents, teachers and the community to recognize their world and provide opportunities to develop within their potential. Like a form of giving rules that are looser but still controlled because they are starting to be independent. Giving praise, appreciation, affection, and growing confidence in interacting with the environment. Confidence here is when a child feels he is capable and dares to be different and holds firm to his principles when what he brings is true. The role of the counseling teacher or counselor is not only focused on helping students with problems, but on assisting all students in developing a variety of potentials, including the development of learning/academic, career, personal, and social aspects. Keywords: Teenager, psychology , counselor

Abstract

Guidance and Counseling Management is very important in improving the quality of education by providing the support and intervention that students need to reach their maximum potential. In an effort to improve the quality of education, BK management must also be oriented towards customer satisfaction, namely students and parents. BK management must be able to provide very high satisfaction to customers by improving the quality of BK services and increasing student participation in the learning process. This article examines how the implementation of effective BK management can improve the quality of education through strengthening learning motivation, improving student behavior, and reducing the level of delinquency. teenager. Through literature study, it involves theoretical studies. The research results show that good guidance and counseling management contributes significantly in shaping students' character and academic achievement, thus emphasizing the importance of integrating guidance and counseling in strategies to improve the quality of education.

Abstract

In this research, cellulose acetate fiber was produced by electrospinning method. Cellulose acetate was dissolved with acetone solvent and then putin to a cooling system torestrain the rate of evaporation of cellulose acetate. The conductivity and evaporation rate of the cellulose acetate solution were tested, and the cellulose acetate fiber sproduced were tested using scanning electron microscopy (SEM). The conductivity of the cellulose acetate solutionwas 3.45 S/cm at 15oC and almost doubled at 22oC. The cooling system test was ableto maintain the temperature of the cellulose acetate solution at 15 oC for approximately 2 minutes. In addition, bead fibers are produced due to their low conductivity.

Abstract

The amount of fuel reserves were getting depleted and has created problems with the occurrence of a fuel crisis, which has resulted in higher prices and the economy of the community has been down. Biomass is a renewable alternative fuel source but still has weaknesses, like high water content, low calorific value and low density and the combustion process requires high temperatures. To overcome this problem, biomass can be processed into biopellets with the aim of increasing its density and increasing the quality of combustion. The research was about the processing of cocoa and candlenut shell waste as an alternative fuel in the manufacture of biopellets using tapioca adhesive. The stages of this research include the preparation of raw materials for cocoa shells and candlenut shells ground to a size of 60 mesh and then added with various adhesives of 5%, 10% and 15%, then printed manually and dried in an oven with a temperature of 60oC for ±3 hours. Furthermore, the biopellets were characterized based on the provisions of SNI 8021:2014 which included density, moisture content, ash content, volatile matter, fixed carbon, calorific value with the most optimum values, respectively, 1.02 g/cm3, 3.14%, 6 ,25%, 64.56%, 26.05% and 4145.6 cal/g. Biopellets were also tested for effectiveness such as fracture strength and combustion rates with values of 0.14% and 0.11 g/min, respectively. Biopellet with the best quality was found in the type of biopellet with a mixture of raw materials 2:1 and using 10% tapioca adhesive.

Abstract

Paper production is currently important for various community needs due to the use in daily life. The aim of this study is to produce paper cellulose-based extracted from Nata de Coco with the addition of polyvinyl alcohol (PVA) as an adhesive. The paper was produced by using pulp method followed by ultrasonication with variation of ultrasonication from 10 min, 20 min, to 30 min. The sample was characterized in terms of functional groups and mechanical properties. The results showed that the longer the ultrasonication time, the lower the mechanical value. The highest tensile test was obtained at 10 min of ultrasonication with the value of 5.036 MPa.

Abstract

We simulated 17 molecules classified as Naphthoquinones derivatives with the Enzyme Elastase to observe data regarding energies produced after bonding. These 17 Molecules were Eleutherin, Isoeleutherin, Elacanacin, Eleutherinone, Eleutherol A, Eleutherol B, Eleutherol C, Eleuthinones B, Eleuthinones C, Eleutherine A, Eleutherine B, Eleutherine C, Eleutherine D, Eleutherine E, Eleutherine F, Eleutherine G, Eleucanainones A. To prepare the ligand and protein for docking, we used the Discovery Studio application. For the molecular docking itself, we used the Pyrx application. Regarding interpreting the result, first, we chose the lowest rmsd/ub or rmsd/lb, and then we analyzed the energy result in which the lowest rmsd occurred. The docking results data indicated that all the ligand-enzyme bonding had negative binding affinity energy, but Eleucanainones A produced the lowest energy (Binding Affinity -7.7, mode 1, Rmsd/ub 1.787, Rmsd/lb 3.54), meaning it bound most easily with the enzyme Elastase. This study was only an initial or foundational step and further studies were highly needed for the development of the correlation between the ligands and the enzyme mentioned above.

Abstract

An organic ester with good mechanical characteristics (such as a high Young's modulus and tensile strength) is cellulose acetate (CA), a biobased polymer. Over the past few decades, the thermal characteristics of CA have been extensively studied. This study looked at the morphology and thermal characteristics of plasticized CA, particularly its mass loss according to thermogravimetric analysis. The analysis and comparison of the overall thermal behavior with theoretical models was done. The results of this study may have particular significance as certain polymers have a recognized dependence on β-relaxation for their mechanical attributes; this may also apply to CA.

Abstract

Limbah asap cair industri santan kelapa merupakan limbah yang memiliki nilai tinggi dan perlu dimanfaatkan. Senyawa yang terkandung dalam asap cair bisa digunakan sebagai biopestisida secara alat destilasi sederhana. Dalam kegiatan pengabdian ini, mitra yang dilibatkan adalah Ibu-Ibu PKK Desa Sigara Gara yang tergabung dalam kelompok Dapur Emak berusia 30 – 50 tahun. Tahapan kegiatan ini terdiri atas tiga, yaitu tahapan persiapan, pelaksanaan, dan evaluasi. Seperangkat alat destilasi sederhana telah berhasil dirangkai. Asap cair sebelum didestilasi berwarna hitam pekat berubah menjadi warna bening setelah didestilasi. Kelompok yang mengikuti kegiatan pengabdian merasakan manfaat yang positif dimana dapat memanfaatkan limbah asap cair sebagai biopestisida yang ramah lingkungan dan ekonomis.
