Abstract

Adding the nutritional content of broth powder without destroying the distinctive taste of the broth can be doneusing pure mushroom extract and additional vegetables and spices. This study aims to determine the organolepticcharacteristics and identify the chemical functional groups of glutamic acid in the best samples of oyster mushroombroth powder added with vegetables and spices. The results of the organoleptic test were tabulated in a table andthen analyzed using a descriptive test. The organoleptic characteristics of the best color parameters were intreatment B1 which had a pale white color. The best treatment of aroma, texture, and taste parameters were foundin the B2 treatment with a characteristic aroma of typical broth, fine powder texture, and has a distinctive taste ofbroth. The identification of the functional groups of secondary metabolites using the Fourier Transform Infrared(FTIR) instrumentation. Identification results with FTIR showed absorption at wave number (cm-1): 3419.74,2934.62, 1639.56, 1409.70, 1055.55. There is N-H, O-H, C-H, C=O carbonyl group and carboxylic C-O, whichidentify the presence of amide compound, phenol acid, alkane, aldehydes, amid I and carboxylic acid, which areknown as glutamic acid in this sample.

Abstract

This study aimed to determine the effect of PBLRQA strategy combined with learning journals on biology cognitive retention and scientific attitudes of students with different academic abilities. This study was a quasi-experimental using a pretest-posttest nonequivalent control group design 2 x 2 factorial pattern. The research sample was 4 classes in class XI MIA SMAN 17 Makassar, selected by random sampling. Each 2 classes are taught with PBLRQA combined with a learning journal and 2 classes are taught with PBLRQA. The research instrument consisted of cognitive retention instruments in the form of essay tests and scientific attitude instruments in the form of questionnaires and scientific attitude observation sheets. Data were analyzed descriptively and inferentially. The results showed that (i) there was difference in the retention of students with different academic abilities between students taught with PBLRQA combined with learning journals with PBL. The PBLRQA combined with learning journals has more potential to maintain student retention than PBL. The mean corrected retention value of students with higher academic ability compared to students with lower academic ability. The interaction between learning strategy and academic abilities influences student retention; and (ii) there was differences in the scientific attitudes of students with different academic abilities between students who was taught with PBLRQA combined with learning journals and PBL. The PBLRQA strategy has more potential to grow students' scientific attitudes than PBL. The mean corrected scientific attitude of students with higher academic ability compared to students with lower academic ability. The interaction between learning strategies with academic abilities affect the scientific attitude of students.

Abstract

This research aims to determine the comparison of student’s biological problem-solving skill that learned problem-based learning model with direct instructions model on biology subjects the concept of growth and development of plant. This research used a quasi-experimental non-equivalent control group design. This research samples is student of SMAN 12 Luwu class XII IPA selected by random sampling. Data analyzed by ancova test. Data analysis result show value p ≤ α 0,05 (p=0,010) indicating that there are difference of biological problem-solving skill which learned with PBL model and direct instruction model. Result of student’s biological problem-solving skill which learned with PBL model higher compared with learned use direct instruction model. The use of problem-based learning model on the learning activity needed to suitability with the study until learning more effective.

Abstract

Stunting adalah suatu kondisi yang menunjukkan adanya hambatan pertumbuhan yang bersifat kronis yang disebabkan oleh malanutrisi jangka panjang. Tujuan dari penelitian ini adalah untuk mengetahui prevalensi kejadian stunting pada balita yang dihubungkan dengan pola asuh ibu. Penelitian ini merupakan penelitian deskriptif korelasional dengan desain penelitian yang digunakan dalam penelitian ini adalah cross sectional study. Data yang diperoleh dianalisis menggunakan statistik deskriptif dan statistik inferensial dengan menggunakan pengolahan data Statistical Package For Social Sciense (SPSS). Berdasarkan hasil penelitian diketahui bahwa pola asuh ibu (responden) di Desa Tamalate Kecamatan Galesong Utara Kabupaten Takalar Tahun 2023, sebagian besar menganut pola asuh ibu dalam pemberian makan kategori demokratis yaitu 14(26,9%) responden, kategori otoriter sebanyak 11 (21,2%) responden, kategori permisif sebanyak 9 (17,3%) responden, dan kategori pengabaian sebanyak 18 (34,6%) responden. Sehingga prevalensi stunting pada balita responden di Desa Tamalate Kecamatan Galesong Utara Kabupaten Takalar Tahun 2023, sebagian besar mengalami stunting 43 (82,7%) responden. Terdapat hubungan pola asuh ibu dalam pemberian makan dengan prevalensi atau kejadian stunting pada balita di Desa Tamalate Kecamatan Galesong Utara Kabupaten Takalar Tahun 2023 (ρ 0,028; r 0,305).
