Abstract

This research is motivated by the low learning outcomes of students in several subjects. One of them is economics. One of the efforts that can be done to overcome these problems is the use of Problem Based Learning learning strategies in learning. The purpose of this research is to reveal the effect of problem based learning learning model and motivation on students' economic learning outcomes. The type of research used is Quasi Experiment using a 2x2 factorial design. The population in this study were students of class XI IIS-1 MAN 1 West Lombok, NTB for the 2021/2022 school year. The sample of this study was selected by simple random sampling technique with the results of students in class XI IIS-1 MAN 1 West Lombok as samples. The research data were obtained from the results of the economics study test and a learning motivation questionnaire. Data analysis was performed using the t-test and Two-Way ANOVA. The results showed that the economic learning outcomes of students who were taught using the problem based learning model were better than those of students who were taught using conventional learning. This also applies to students who have high and low motivation. Economic Learning Outcomes (cognitive, affective, and psychomotor) students who have high motivation who are taught by PBL learning model are better than students who have high motivation who are taught by conventional learning. The same thing is also shown in students who have low motivation and are taught with the PBL learning model looks better than students with low motivation who are taught by conventional learning.

Abstract

Kuda merupakan salah satu hewan yang penting dalam produksi plasma antisera sebagai bahan baku pembuatan serum. Akhir abad ke-19 kuda berperan krusial dalam pengembangan serum pertama terhadap penyakit difteri manusia. Hingga saat ini kuda masih digunakan untuk memproduksi berbagai serum anti-venom, anti-rabies, anti-tetanus, hingga anti-SARS CoV-2. Proses produksi plasma antisera diawali dengan injeksi imunogen pada kuda yang disebut dengan hiperimunisasi. Antibodi dalam jumlah besar yang terbentuk dikoleksi kemudian dipurifikasi untuk digunakan pada manusia. Hiperimunisasi menimbulkan berbagai efek samping, diantaranya adalah penimbunan fibril amiloid pada berbagai jaringan yang dapat mengganggu fisiologi dan fungsi organ tubuh. Sebanyak 12 ekor kuda digunakan dalam penelitian ini dan dibagi menjadi 4 kelompok. Kuda kontrol (n=3) terdiri atas kuda yang belum pernah mendapatkan perlakuan hiperimunisasi, sedangkan 9 kuda lainnya dikelompokkan berdasarkan lamanya waktu produksi plasma antisera dengan metode hiperimunisasi (masing-masing kelompok berjumlah 3 ekor). Kelompok I terdiri atas kuda dengan masa produksi 2-3 tahun, kelompok II terdiri atas kuda dengan masa produksi 4-5 tahun, dan kelompok III terdiri atas kuda dengan masa produksi 6-7 tahun. Sampel darah, serum, dan aspirasi sumsum tulang dianalisis utuk menghitung niali eritrosit, Hb, PCV, trombosit, profil besi (besi serum, UIBC, TIBC, saturasi transferin), rasio mieloid:eritroid (M:E) dan persentase retikulosit. Analisis statistik menunjukkan bahwa terdapat perbedaan yang signifikan pada parameter eritrosit dan rasio M:E (P<0,05), sedangkan niali Hb, PVC, trombosit, prosentase retikulosit, dan profil besi tidak ditemukan perbedaan yang signifikan (P>0,05). Data tersebut menunjukkan bahwa perlakuan hiperimunisasi menyebabkan penurunan eritrosit dan peningkatan nilai rasio mieloid:eritroid (M:E) pada kuda penghasil plasma antisera.

Abstract

Perguruan tinggi sebagai tempat insan akademik berkiprah saat ini mengalami berbagai tantangan dan ancaman yang dapat mengganggu fungsinya sebagai pusat pengembangan ilmu pengetahuan dan teknologi (iptek), serta menjadi penjaga keberlanjutan peradaban dan moralitas insan akademik agar tidak terdistorsi dan tererosi. Kemajuan teknologi (khususnya teknologi informasi), dekadensi moral global, tekanan ekonomi, orientasi praktis dan fokus pada pencapaian jangka pendek, perubahan paradigma pendidikan serta iklim ketidakpastian, menjadikan nilai-nilai tradisional perguruan tinggi terancam tergeser menjadi mesin penghasil tenaga kerja semata. Perguruan tinggi, yang seharusnya berperan sebagai benteng terakhir penjaga nilai-nilai akademik, serta sebagai agen perubahan (agent of change) yang berorientasi pada nilai kebaikan dan penjaga nilai moral (guardian of value), perlu jati diri insan akademik yang unggul, sehingga peran dan fungsi perguruan tinggi dapat tetap dipertahankan. Untuk memberikan pertimbangan dalam upaya menjaga tersebut, Policy Brief ini disusun melalui serangkaian proses diskusi anggota tim PAH Jati Diri Insan Akademik dan proses FGD yang melibatkan narasumber internal dan eksternal IPB. Policy Brief ini diakhiri dengan rekomendasi yang dapat diusulkan kepada penyelenggara pendidikan tinggi Indonesia agar fungsi perguruan tinggi dan insan akademik dapat tetap terjaga

Abstract

In vitro analysis of oligosaccharide from extract rumbia fruit (Metroxylon sago Rottb.) as prebioticABSTRACT. Despite a range of commercially available oligosaccharides there is plenty of room to develop new, functionally enhanced prebiotics. current generation of oligosaccharides was not rationally developed. better understanding of factors determining the prebiotic activity of a particular oligosaccharide. Despite the range of commercially available oligosaccharides mixtures (mainly fructo and galacto-oligosaccharides), very few studies are focused on the mechanisms behind the prebiotic activity of particular oligosaccharides. Probably this lack is due to the unavailability of well characterized oligosaccharide fractions for prebiotic function assessment. The objectives of this research were to asses the ability of lactic acid bacteria in fermentation of oligosaccharide and as prebiotic (in vitro). Material used was oligosaccharide of purified rumbia fruit extract. Analysis of oligosaccharide as prebiotic was conducted in vitro using lactic acid bacteria. The lactic acid bacteria consisted Bifidobacterium bifidum, Bifidobacterium animalis, Lactobacillus bulgaricus and Lactobacillus casei Rhamnosus. The growth media for bacteria was a liquid MRS basic medium where glucose was substituted by oligosaccharide of purified rumbia fruit extract. Incubation was in aerob for Lactobacillus and anaerob for Bifidobacterium in incubator 37oC. The lactic acid bacteria was calculated 24-48 hours during incubation periode. The variables observed were: oligosaccharide component, ability of lactic acid bacteria in fermentation of oligosaccharide, and growth of lactic acid bacteria (Lactobacillus and Bifidobacterium). The result showed that the oligosaccharide component from extract rumbia fruit consisted of: sucrose, stacchiose, and raffinose. The result showed that the oligosaccharide extract rumbia fruit was significantly (P0.05) the growth of lactic acid bacteria (Lactobacillus and Bifidobacterium) and fermentation of oligosaccharide. It is concluded that oligosaccharide of rumbia fruit extract could be used as prebiotic.

Abstract

Effect of prebiotic oligosaccharide extract rumbia fruit (Metroxylon sago Rottb.) in the ration on broiler performanceABSTRACT. Prebiotic oligosaccharides are thought to provide beneficial effects in the gastrointestinal tract of humans and animals by stimulating growth of selected members of the intestinal microflora. Prebiotic oligosaccharides are defined as nondigestible food ingredients that provide beneficial effects to the host by stimulating the growth of selected microbial members of the gastrointestinal tract. Among the colonic bacteria capable of metabolizing prebiotic oligosaccharides and whose growth is stimulated are species of Lactobacillus and Bifidobacterium. Prebiotic oligosaccharides can be produced in transgli-cosylation reactions catalyzed by glycosidases. Glycosidases from different biological sources have specific ability to catalyze the formation of oligosaccharides with particular chain lengths (usually DP 7) and predominant glycosidic linkages. Oligosaccharide used this research was purified rumbia fruit extract as prebiotic for feed additive in the ration on broiler. The objectives of this research were to study the performance of broiler given of prebiotic oligosaccharide extract rumbia fruit (metroxylon sago Rottb.) in the ration. Two hundred day-old chicks of broiler were divided into three dietary treatments and four replications. Ration used was consisted of: R1 = basal ration (control), R2 = basal ration + 0,4% oligosaccharide extract rumbia fruit, and R3 = basal ration + 0,4% frukto-oligosaccharide (FOS). The variables observed were: feed consumption, body weight, feed conversion ratio, mortality, and production index. The result showed that the performances of the broiler supplemented prebiotic oligosaccharide extract rumbia fruit (R2) was significantly (P 0.05) differences between of feed consumption, body weight, and mortality. It is concluded that of prebiotic oligosaccharide extract rumbia fruit were able to decrease the mortality and feed consumption at six week of age.

Abstract

Black cumin (Nigella sativa) is a herbal plant that has been cultivated locally in Indonesia and is traditionally used for various diseases. Thymoquinone, one of the main components, is rich in biological activity. In several countries, topical application of its oil on human skin with vitiligo can stimulate skin repigmentation with minimal side effects. This study aims to determine the viability of B16F10 melanoma mouse cells against ethanol and n-hexane extracts of black cumin seeds through the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The ethanol extract (EE) yield was 14.306%, and the n-hexane extract (NHE) was 7.442%. Phytochemical screening of EE detected flavonoids, alkaloids, saponins, and steroids, and High-performance liquid chromatography (HPLC) detected 0.040% thymoquinone. The MTT test showed cell viability was >100% from EE at all treatment concentrations, namely 0.75-100 ppm and only 0.75-6.25 ppm for NHE. In conclusion, this study indicates that 96% EE of Nigella sativa is less toxic than NHE on B16F10 mouse melanoma cells and has potential as an alternative treatment for vitiligo, which needs to be proven in further research.

Abstract

Kulit ikan salmon merupakan salah satu produk samping yang dapat menghasilkan kolagen. Ada beberapa cara untuk mengekstraksi kolagen, salah satunya dengan menggabungkan proses kimia (asam) dan enzimatik (protease). Kolagen larut papain (PaSC) adalah istilah yang digunakan untuk menggambarkan kolagen yang diekstraksi. Kolagen yang diekstrak dari kulit ikan menggunakan enzim tumbuhan berpotensi menjadi sumber kolagen halal. Penelitian ini bertujuan untuk mengetahui waktu ekstraksi optimum, konsentrasi, dan karakter PaSC dari kulit ikan salmon. Kombinasi asam asetat konsentrasi 0,5 M dan enzim papain 1000 U/mg/g kulit selama tiga hari menghasilkan kelarutan kolagen yang maksimal. Rendemen PaSC dari kulit ikan salmon sebesar 15,58% (db). Asam amino yang paling umum di PaSC adalah prolin, glisin, dan arginin. Kisaran distribusi berat molekul kolagen ditentukan sebesar 20-142 kDa. Struktur triple helix tidak diubah oleh ekstraksi PaSC, menurut spektrum FTIR
