Abstract

The aim of this study was to evaluate the nutritive value and fermentation characteristic of king grass silage treated with addition of liquid or dried lactic acid bacteria (LAB) inoculant. Experiment was arranged to a completely randomized design with four treatments and three replications. Four treatments as follows (A) king grass without LAB inoculant as the control; (B) king grass + 30 ml of liquid of epiphytic LAB inoculant/kg of fresh forage; (C) king grass + 30 g of freeze-dried powder of LAB inoculant/kg of fresh forage; (D) king grass + 30 g of centrifuged powder of LAB inoculant/kg of fresh forage. The liquid LAB inoculant was sprayed on the top of grass and then mannualy mixed by hand. The intial LAB concentration in all inoculants were 1.0 × 106 cfu/g. About 500 g of silage materials were ensiled into plastic silos and stored at room temperatures (approximately 28oC) for 30 days. Results showed that pH value, concentrations of lactic acid, N-amonia (NH3-N), butyric acid and total volatile fatty acids (VFA) as well as Fleigh Point were affected by treatment of LAB inoculant. Silage treated with liquid or dried of LAB inoculant had lower (P

Abstract

Abstrak: Perilaku hidup bersih di era Covid-19 dapat dilakukan dengan cara menggunakan desinfektan dan antiseptik. Antiseptik sendiri digunakan untuk membunuh kuman atau mikroba pada tubuh organisme. Salah satu penggunaan antiseptik yang lagi marak di era covid-19 adalah hand sanitizer. Pengabdian bertujuan untuk meningkatkan keterampilan masyarakat dalam membuat hand sanitizer berbahan dasar daun sirih dan jeruk nipis. Pengabdian dilakukan melalui proses penyuluhan dan pelatihan. Lokasi pengabdian adalah Kecamatan Yendidori Kabupaten Biak Numfor Provinsi Papua. Hasil pengabdian menunjukkan bahwa pengetahuan masyarakat bertambah tentang pengertian (sebesar 71.43%), fungsi (sebesar 57.14%), dan bahan dasar hand sanitizer (sebesar 100%). Keterampilan dalam membuat hand sanitizer bertambah sebesar 92.86%. 100 % masyarakat merespon dengan baik kegiatan pengabdian yang dilaksanakan. Kesimpulan yang diperoleh dari hasil pengabdian ini adalah bahwa masyarakat Kampung Impendi memperoleh peningkatan informasi dan keterampilan dalam pembuatan hand sanitizer dari bahan alami. Pelatihan pemanfaatan bahan alami untuk dijadikan hand sanitizer atau antiseptik lainnya perlu dilakukan secara terus menerus.Abstract: Clean living behavior in the Covid-19 era can be conducted by using disinfectants and antiseptics. Antiseptic itself is using to kill germs or microbes in the organism's body. One of the more prevalent uses of antiseptics in the Covid-19 era is a hand sanitizer. The community service aims to improve community skills in making hand sanitizers made from betel leaf and lime. Community service was carried out through a process of socialization and training. The service location is Yendidori District, Biak Numfor Regency, Papua Province. The service results show that people's knowledge increases about understanding (by 71.43%), function (by 57.14%), and the essential ingredients of hand sanitizers (by 100%). The skill in making hand sanitizers increased by 92.86%. 100% of the community responded well to the service activities carried out. The conclusion obtained from this service results is that the people of Impendi Village received increased information and skills in making hand sanitizers from natural ingredients. Continuous socialization and training on the use of natural ingredients as hand sanitizers or other antiseptics are necessary.

Abstract

Riset ini bertujuan untuk mengkaji perbedaan motivasi diantara dua gender (laki-laki dan perempuan) di saat pandemi, khusus untuk pelajaran biologi. Metode penelitian survey dengan pendekatan kuantitatif telah digunakan dalam riset ini. Sebanyak 191 siswa disurvey dengan angket untuk mendapatkan data motivasi mereka. Angket berisi 31 pernyataan dengan empat skala yang tersebar pada lima indikator motivasi. Data dikalkulasi dengan uji t dan Mann-Whitney. Hasil menunjukkan perbedaan signifikan (p < 0.05) untuk skor total motivasi dianatar kedua gender. Berdasarkan indikator motivasi, ditemukan dua indikator berbeda signifikan dan tiga indikator lainnya tidak menujukkan signifikan untuk kedua gender. Riset ini menyimpulkan bahwa motivasi siswa laki laki dan perempuan untuk belajar biologi adalah berbeda, tetapi berdasarkan indikator hanya berbeda signifikan pada dua indikator saja yaitu semangat dan kebutuhan (M2) dan Harapan dan cita-cita (M3).

Abstract

Abdopus aculeatus has good camouflage capabilities in nature. The objective of this study is to obtain information on the camouflage behavior of Abdopus aculeatus in nature (in situ). We used an explorative description to observe the camouflage behavior of 24 octopus samples at a number of points on the Panjang Island, Buton Regency. Abdopus aculeatus was identified molecularly using a mtDNA COI blast to determine the target species of observation. Any of the camouflage behavior found was documented and analyzed descriptively. Generally, there are four forms of observations for camouflage behavior; matching body color to wide array of natural background, immersing itself in the sand, resembling a specific object, and being part of the objects surrounding. The various camouflages patterns obtained show a process of defense evolution in minimizing the detection of predators or octopus prey.

Abstract

Background: Since COVID-19 learning has been limited and shifted to online learning. Teacher creativity in learning is needed to strengthen student learning outcomes. This study aims to investigate the effect of using comics on student learning outcomes on the material of the human digestive system. Methods: A quasi-experimental research was used on forty-two junior high school students who were randomly selected. Multiple choice tests are used to obtain student learning outcomes. Free sample t-test was used to compare student learning outcomes in comic and non-comic classes. Results: The findings revealed that the average student learning outcomes were better when they were taught using comics than non-comics (p = 0.000 < 0.05). Conclusion: Based on the results of the study, it can be concluded that learning with the application of comic media in science subjects on the human digestive system material has an influence on learning outcomes, with the difference in student learning outcomes in the experimental class being higher than in the control class.

Abstract

This study aims to determine the various kinds of compounds from the saponin group found in local Indonesian garlic and map the biological potential of these compounds, especially the potential in the health sector. Saponins are a group of compounds characterized by the presence of foam. Saponins have various benefits both in the health, agriculture, animal husbandry, and also in the food and cosmetic industries. Fifteen compounds from the saponin group were identified from local Indonesian garlic obtained from West Papua, using Liquid Chromatography Mass Spectrometry (LCMS) and validated based on their similarity with the NCBI PubChem database. Saponin compounds in local Papuan garlic, then, their biological potential was mapped using the PASS Server and showed that there were seventeen kinds of biological potential in the saponin compound group from Indonesian local garlic. The three most dominant potencies are as anticancer, antifungal, and hypolipemic. Based on this research, it can be concluded that Indonesian local garlic has great potential to be developed and applied in the health sector, especially as an anticancer related to the saponin content in tubers.

Abstract

Contextual Teaching and Learning (CTL) is a learning concept helps teachers relate subject concepts to real-world situations and student engagement to find materials learned and connect in everyday life. This study aims to determine the influence of CTL to improve student learning outcomes on environmental pollution materials during pandemics. The research was conducted at Manokwari Advent Junior High School in April-May 2021. The sample of learning grade VII A (experimental class) number of learners as many as 22 people and grade VII B (control class) the number of learners 20 people. This research method was quasi-experimentation with a nonequivalent control group design, an instrument used in research in the form of cognitive tests in the form of multiple choice. Analysis of data mechanisms used in the study was a normality test, homogeneity testing, and followed by hypothesis testing using the SPSS IMB 20 mentoring program. After the test was obtained, the results of the learning class experimental have an average post-test of 86.25, while the value of the post-test control class is 45.25; then, it can be concluded that the CTL model can improve the learner learning outcomes
