Abstract

ABSTRAK Telah diisolasi dua senyawa fenolik dari fraksi ekstrak kasar metanol daun kering Aglaia speciosa. Pemisahan komponen dilakukan dengan kromatografi kolom secara elusi bergradien (n-heksana : etil asetat : metanol) kemudian diikuti dengan penghabluran ulang menggunakan n-heksana : etil asetat. Senyawa pertama (non flavonoid) berupa amorf putih (dekomposisi 257 oC), dari spektrum UV memperlihatkan λmax (metanol) 235 nm, 275 nm (bahu) dan spektrum IR dengan serapan penting pada 3200 cm-1, 1625 cm-1, 1465 cm-1, dan 840 cm-1. Senyawa kedua berupa amorf kuning muda (dekomposisi 227 oC) dan berdasarkan spektrum UV dan IR, disarankan sebagai 5, 7, 4’ –trihidroksiflavon yang merupakan tipe viteksin. Struktur sebenarnya dari kedua senyawa tersebut belum dapat ditentukan. Kata kunci: daun Aglaia speciosa, fenolik, flavonoid, viteksin. ABSTRACT Two phenolic compunds have been isolated from ethyl acetate fraction of the crude metanolic extract from A. speciosa dried leaves. It was separated by column chromatography with gradient elution (n-hexane : ethyl acetate : methanol) then followed by precipitation from n-hexane : ethyl acetate. The first isolate was a non flavonoid, white amorphous solid (dec. 257 oC), UV spectra λmax (methanol) 235 nm, 275 nm (sh) and IR spectra vmax KBr 3200 cm-1, 1625 cm-1, 1465 cm-1 and 840 cm-1. The second isolate was a light yellow amorphous solid (dec. 227 oC) and suggested as 5,7,4’-trihidroxyflavone of vitexin type base on its UV and IR spectra. The exact structure of those two compounds could not be determined yet. Key words: Aglaia speciosa leaves, phenolic, flavonoid, vitexin.

Abstract

Penelitian ini bertujuan mengeksplorasi pengaruh jenis koagulan pada berbagai konsentrasi terhadap fraksi protein curd yang dihasilkan serta korelasinya terhadap tekstur. Koagulan yang digunakan yaitu CaSO4. 2H2O dan CH3COOH pada konsentrasi 0,015 N, 0,03 N dan 0,045 N. Fraksi protein curd didapat dengan fraksinasi Osborne dan dianalisis lebih lanjut dengan metode sodium dodecyl sulfate - polyacrylamide gel electrophoresis (SDS-PAGE). Fraksi protein yang didapat dari fraksinasi Osborne yaitu albumin. globulin, prolamin, dan glutelin. Tekstur Curd kedelai dianalisis secara objektif dengan texture profile analysis (TPA) yang mencakup kekerasan, elastisitas, kohesivitas, dan gumminess. Dari hasil penelitian diketahui bahwa proses pengolahan kedelai menjadi curd menyebabkan penurunan konsentrasi fraksi protein albumin dan globulin yang signifikan. sebaliknya konsentrasi fraksi protein glutelin meningkat secara drastis. Pada konsentrasi koagulan 0.045 N. terdapat variasi pola pita fraksi protein SDS-PAGE pada kedua jenis curd(CaS04.2H20  dan CH,COOH). Jenis dan konsentrasi koagulan juga diketahui berpengaruh nyata terhadap profil tekstur objektif curd (p=0,05).Terdapat korelasi yang signifikan antara kadar fraksi protein terhadap profil tekstur objektif curd CaS04.2H2O. Sebaliknya, tekstur objektif curd CH3COOH kurang dipengaruhi oleh kadar fraksi protein. Effect of Coagulant Type and Concentration Toward Coagulated Protein Fraction and Soy Curd Texture (Glycine max] The aims of this research were to explore the effect of coagulant type and coagulant concentration on curd protein fraction. curd texture, and the correlation between these variables. Coagulants used were CaSO4. 2H2O and CH3COOH with 0.0 I5 N, 0.03 N, and 0.045 N concentration. Curd protein fractions were obtained by Osborne fractionation and was further analyzed using sodium dodecylsulfate acrylamide gel electrophoresis (SDS­ page) method. The protein obtained were albumin, globulin. prolamin, and glutelin. Curd textures that include hardness, elasticity, cohesiveness, and gumminess were analyzed by texture profile analysis (TPA). The result showed that conversing soybean to be curd caused decreasing of albumin and globulin concentration significantly. In contrast, glutelin concentration was increasing significantly. There were variations of protein fraction pattern of band SDS-PAGE between two type of curd (CaSO4. 2H2O and CH3COOH) in 0.045 N. Types and concentrations of coagulant were also influenced significantly to curd texture profile (p=0.05). There was a significant corelation between protein fraction content on objective texture profile of CaSO4. 2H2O curd. On the other hand the objective texture profile of CH3COOH curd was not influenced by protein fraction content.

Abstract

Value is an abstract concept that is discovered in every human being and becomes extremely significant in every aspect of life. All human activities in daily life are always filled with a variety of values. This is done, of course, by incorporating moral values that are believed to be true, such as those contained in Pancasila, namely, by integrating divine values, human values, values of unity, populist values, and values of justice in various aspects of the younger generation's lives, so that the younger generation of the future will be the young generation of Indonesia with the character following the values contained in Pancasila. The younger generation is a generation that understands the values of human behavior related to God Almighty, oneself, fellow human beings, the environment, and nationality which are manifested in thoughts, attitudes, feelings, words, and actions based on religious norms, laws, regulations. manners, and culture.Keywords: Pancasila, Cultural Diversity, Character, Young Generation.

Abstract

The purpose of this research is to investigate the implementation andimpact the program of the ToT Nilai-nilai Kebangsaan Lemhannas RI forteachers and lecturers in West Java Province. Some previous researchesexplained that radicalism growth in the world of schooling in West Java. Fromthe internalization of national values carried out by teachers towards students, itwas formed as an effective strategy as well as a model of deradicalization inschooling. This research was conducted using a qualitative approach. Interviewsand observations were chosen as data collection techniques to obtain deepresults. The results of this research were that the teachers who were alumni of theToT Nilai-nilai Kebangsaan Lemhannas RI generally participate in socializingnational values in learning through varied methods in accordance with thesubjects they are taught. There were differences way or method in implementingnilai-nilai kebangsaan into the course, even though student’s respond wasenthusiast.
