Abstract

Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Mahasiswa (LKM) Dasar-dasar IPA yang diharapkan dapat membekali mahasiswa calon guru IPA dengan keterampilan proses sains sekaligus nilai-nilai positif melalui pendidikan karakter. Pendidikan karakter ini dianggap perlu karena maraknya konflik-konflik intoleransi dan keadilan sosial yang terjadi di masyarakat akhi-akhir ini. Hal ini menunjukkan bahwa nilai-nilai integritas bangsa Indonesia perlu mendapatkan perhatian, terutama dalam hal etika, moral, dan kepercayaan. Pentingnya nilai-nilai ini karena semangat gotong royong dan saling bekerjasama merupakan karakter Bangsa Indonesia. LKM yang dikembangkan melalui tahapan perancangan, penyusunan, validasi, dan revisi sehingga dihasilkan produk LKM Dasar-dasar IPA berbasis model ALLR (Activity Based-Lesson Learn-Reflection). Hasil pengembangan LKM menghasilkan empat kegiatan LKM yang dibagi menurut topik pembahasan yang berbeda-beda dengan menggunakan serangkaian aktivitas yang diharapkan dapat meningkatkan keterampilan proses sains. Selain itu, LKM juga dirancang untuk pengintegrasikan pendidikan melalui pembelajaran pemaknaan konten-konten IPA ke dalam nilai-nilai positif yang berkaitan dengan nilai toleransi dan keadilan sosial. Hasil validasi menunjukkan bahwa LKM Dasar-dasar IPA layak digunakan dengan nilai presentase validasi LKM 1 sebesar 76.79%, LKM 2 sebesar 82.14%, LKM 3 sebesar 92.85%, dan LKM 4 sebesar 76.78%.

Abstract

Scientific literacy is very important to generation Z (Gen-Z), while Gen-z’s scientific literacy in Indonesia needs to be improved. The use of gadgets by Gen-Z almost all the time in their daily lives enables research to improve scientific literacy by using gadgets. This study aims to determine the effectiveness of gadget-based interactive multimedia to improve Gen-Z scientific literacy and describe the Gen-Z response to interactive multimedia. This research was a pre-experiment study with one group pretest and posttest design. Interactive multimedia was designed to be applied on gadget, consists of Socioscientific Issues (SSI) which was relevant to pressure concepts. This research involved two junior high schools in East Java, Indonesia. Scientific literacy test instrument was designed based on scientific literacy aspects of PISA 2015. The inferential test results showed that posttest score was significantly greater than the pretest in the two schools. Results showed that the mean score of students’ scientific literacy at School I increased from 39.6 to 74.0 and N-gain score was 0.57 which was in medium category. In addition, the average scientific literacy score of students in School II also increased from 31.5 to 59.9 and Ngain score was 0.41 which was in the medium category. The inferential test results also showed that there were no significant N-gain differences in the two schools. It can be concluded that interactive multimedia developed effective to improve students’ scientific literacy. However, Gen-Z students cannot be satisfied with the multimedia. Students suggest several multimedia enhancements in terms of visual, audio, and music, so that they can enjoy the multimedia all the time by using the device.

Abstract

The community's growing demand for chicken meat as an animal protein source has presented farmers with the challenge to alter the care of broiler chickens by using high cage density. The aim of this study is to investigate the effect of diet supplementation with encapsulated extract of kenikir (Cosmos caudatus) and bitter (Andrographis paniculata) extracts on broiler diet to growth perfor-mance, immunity status, and carcass proportion. A total of 370 day-old Cobb broiler chicks, weighing 45.25 ± 0.89 g, were divided into five groups: T0: control, basal diet + density 10 chicks/m2, T1: basal diet + density 16 chicks/m2, T2: basal diet + density 16 chicks/m2 + Cosmos caudatus 1 g/kg feed, T3: basal feed + density 16 chicks/m2 + Andrographis paniculata 1 g/kg feed, T4: basal feed + density 16 chicks/m2 + Cosmos caudatus 0.5 g/kg feed + Andrographis paniculata 0.5 g/kg feed). At the end of the study, the blood sample and internal organ were collected to further analysis. The final weights of groups T2, T3, and T4 were better than T0 and T1, while T1 has the lowest weight among the other groups. Chicks in T0, T2, T3 and T4 had lower PDW levels compared to T1. Chicks in T4 have a high-er jejunum villi height compared to T0, T1, T2 and T3 groups. The treatments did not affect the small intestine and giblets relative organ wights (P>0.05). The group of T0, T2, T3, and T4 have a fewer duo-denum lesion compared to T1. The group of T2, T3, and T4 have a better structure in jejunum cells compared to T0 and T1. Lesion score of Bursa Fabricius and spleen were greater in T3 and T4 com-pared to T0, T1 and T2 groups. And T1 have the lowest ND antibody compared to other groups. In con-clusion, giving encapsulation of kenikir (Cosmos caudatus) and bitter (Andrographis paniculata) ex-tracts on broiler diet can improve production performance and immune status of broiler chickens.

Abstract

This study evaluated the effects of different frequencies of Spirulina platensis S. platensis )supplementation on blood parameters, protein digestibility, fecal characteristics, egg quality, and production performance in laying hens. A total of 224 ISA Brown hens (55 weeks old, BW ±1907 g) were assigned to four groups: T0 (control, basal feed), T1 (0.5% S. platensis daily), T2 (0.5% every other day), and T3 (0.5% twice a week). The trial lasted for eight weeks, with weekly measurements of feed intake, egg production, and egg quality. Blood was collected at the end of the experiment to assess hematological profiles, while fecal samples were analyzed for protein digestibility and nitrogen excretion. Results showed that T3 and T4 significantly increased red blood cell count, hemoglobin concentration, hematocrit value, and leukocyte count compared to the control (P<0.05). Compared to T0, nitrogen retention and protein digestibility coefficients (%) in T1, T2, and T3 were significantly different (P<0.05). Excretory nitrogen levels in the treatment groups (T1, T2, and T3) were substantial-ly lower than those in T0 (P<0.05). Compared to T0, fecal ammonia levels in the treatment groups (T1, T2, and T3) were lower. The water content in T3 was significantly higher than that in T2 (P<0.05). Haugh Unit values in T1 and T2 were significantly higher than those in T0 and T3 (P<0.05). HDP at weeks 6 and 12 in T1, T2, and T3 were significantly higher than those in T0 (P<0.05). In conclusion, S. platensis supplementation enhanced hematological status, nutrient utilization, fecal characteristics, egg quality, and production performance. Twice-weekly supplementation (T3) was as effective as the more frequent regimens, suggesting a practical and cost cost-efficient strategy for laying hens.

Abstract

Reproductive performance of female cattle is one of the important factors that need to be known in supporting the efficiency of beef cattle breeding programs so that the dam can produce calves every year. This study aimed to evaluate the potential and reproductive performance of female Bali cattle to preparing a baseline for cattle breeding production in SL-SPR Maju Bersama, Sungai Lilin District. Three hundred and thirty female Bali cattle owned by 247 farmers were measured and recorded based on their production and reproduction performance. Data were collected by interview and observation. Data were analyzed using statistical and descriptive methods. Reproductive performance obtained is the age first calving 1098±120 days; calving interval 457,25±8,75 days; days open 109,25±8,57 days and service per conception 5,46±0,42. The average female cattle have a BCS value of 3 (43%). The result showed that the breeding of Bali cattle at SL-SPR had sufficient potential, but it was necessary to improve performance. The basic data obtained can be used to start a breeding business to increase populations and improve the genetic quality of Bali cattle.

Abstract

The present study examined the consequences of supplementing the diets of low-weight day-old broiler chicks (DOC) with 4% infertile egg powder (IEP). The chicks were categorized into three groups namely; normal-weight DOC, low-weight DOC on a basal diet, and low-weight DOC on a diet that contained 4% IEP (T2). In hematological analysis, there was increase in hemoglobin levels, and mean corpuscular hemoglobin concentration (MCHC) compared to T2, but the MCV was less than T0 (p<0.05). There was improvement in the lipid metabolism, whereby triglyceride and HDL levels reduced and increased, respectively (p<0.05). T2 showed an improved antioxidant status; it had an increased activity of superoxide dismutase (SOD) and a decreased level of malondialdehyde (MDA) (p<0.05). Ileal lactic acid bacteria (LAB) and coliform counts were also substantially reduced in T2 vs. T0 (p<0.05), whereas both caecal coliform counts and LNE counts and the LAB-to-coliform ratio were significantly worse in T1 and T2 than T0 (p<0.05). Histological findings expressed the aspect of villus height-to-crypt depth (VH/CD) ratio that was greater in duodenum and ileum of T2 than T1, and deeper crypt in the jejunum in T0 than T1 (p<0.05). There was significant reduction in lesion score in duodenum and the jejunum as seen in T2 group (p<0.05). T2 also had much higher weight gain (p<0.05). per day, feed consumption and body weight at the end when compared to T1. To summarize the findings, the supplement of 4% IEP via the diet improved the physiological functioning and intestinal health status, causing the rise in body weights in low-weight broiler chicks.
