Authors:Dhanang Puspita, Monang Sihombing, Karina Permata Pages: 62 - 68 Abstract: Increased consumption of fruit requires consumers to understand how to choose good and ripe fruit. The level of fruit maturity can be known based on physical characteristics, including the parameters of size, weight, skin color, fragrance of the fruit, and the level of hardness of the fruit flesh. Determining the level of fruit maturity based on physical characteristics has a weakness that is subjective and inconsistent. Making indicators based on natural dyes, namely anthocyanins, to determine the level of sweetness of the fruit. The purpose of this research is to use anthocyanin pigments as an indicator of fruit sweetness level to determine fruit maturity. This research is an experimental laboratory and qualitative descriptive analysis with stages; Sample Extraction, Indicator Making, Indicator Application, Fruit Acidity Testing, Data Analysis. Based on the results of the study, there were quite visible color differences on toothpicks after being inserted into the fruit samples with a sweet taste and the fruit samples with a sour taste. The indicator shows that fruit with a sour taste (pH < 3) changes color from blue to reddish purple. If the taste is not too sour (pH 5), it does not experience a significant color change. In conclusion, the anthocyanins in telang flower can be used as an indicator solution because they have a blue color at neutral pH, a reddish color at pH = 2, the red color fades at pH = 3 and 4, and there is no color change at pH 5.

Authors:Elsa Melisa, Asrul Sahri Siregar, Siti Rukayah Pages: 69 - 81 Abstract: This study aims to determine the composition and value of the natural feed niche of trough fish caught from the waters of the PB Reservoir. Sudirman. The research method used is a survey method with a sampling technique using purposive random sampling. The research location was divided into three stations, namely I (Karang Kemiri), II (Wanadadi), and III (Karang Jambe). Sampling was carried out three times (19 February, 07 March, and 2 August 2020). Data were analyzed descriptively comparatively. The results showed that the composition of the trough fish diet was dominated by Chlorophyta and plant debris. Based on the selectivity index and the most significant part of trough fish, including omnivorous fish. Large trough fish have a high food niche area. Small, medium and large trough fish have stiff competition for food in the waters PubDate: 2021-11-25 DOI: 10.25273/florea.v8i2.11049 Issue No:Vol. 8, No. 2 (2021)

Cabai Merah Besar (Capsicum Annum L.) juga digunakan untuk pengobatan sakit gigi, bisul, anti parasit, anti inflamasi, antitusif dan juga digunakan sebagai antiseptik, nafsu makan. Penelitian ini memiliki tujuan untuk menganalisis potensi senyawa nonivamide dan nordihydrocapsaicin sebagai anti-inflamasi. Kajian penelitian metode in silico. Senyawa Nonivamide (CID :2998) dan Nordihydrocapsaicin (CID: 168836) diperoleh dari PubChem sedangkan COX-2 (6cox) dari Protein Data Bank. Analisis menggunakan HEX 8.0.0 dan ditampilkan Discovery studio client 4.1. Interaksi yang terjadi antara senyawa Nonivamide dan COX-2 membentuk ikatan hidrogen dengan tipe ikatan hidrogen konvensional (CYS47) dan ikatan hidrofobik (LEU152). Selain ikatan hidrogen, juga terdapat sembilan belas residu asam amino menunjukkan adanya gaya Van Der Waals membentuk energi -339.48 cal/mol. Ikatan Nordihydrocapsaicin dengan COX-2 membentuk ikatan pada residu asam amino TRP139 bersifat Pi-Alkyl dan ikatan hidrogen sebagai donor dengan Residu asam amino SER143 energi ikatan sebesar -248.47 cal/mol.

Authors:Eka Nunik Suharjanti, Ipah Budi Minarti, Lussana Rossita Dewi Pages: 89 - 98 Abstract: Assessment is part of a teacher's pedagogic competence and curriculum-13 must carry out cognitive, psychomotor and affective assessments. Online learning causes the implementation of psychomotor and affective assessments to be hampered. This study aims to determine the readiness and understanding of Biology teachers on psychomotor and affective assessments during online learning. The method used is qualitative with descriptive analysis. The sampling technique is a saturated sampling technique. The subject of the study, namely the Biology teacher of the SMA in Comal District, opened 5 teachers through filling out questionnaires distributed online on google forms and RPP documentation as well as evidence of the implementation of the assessment, while the student questionnaires were used as secondary data. Data analysis using descriptive analysis consists of reduction, data display, and verification. This study resulted in the finding that the teacher's assessment readiness profile during online learning can be declared ready to carry out psychomotor and affective assessments. Meanwhile, the profile of teachers' understanding of psychomotor and affective assessments can generally be obtained at a low level. An understanding profile that has an impact on misconceptions in the realm of assessment and the development of an assessment rubric that is not yet good so that human application cannot run optimally. In addition, the application of psychomotor and affective assessments during online learning is influenced by the factors of the teacher's IT ability and the facilities owned by the students.

Authors:Sukian Wilujeng, Hery Setiawan Pages: 99 - 102 Abstract: Penelitian ini bertujuan untuk mengetahui hasil uji coba augmented reality dengan menggunakan WIKU visual dapat diterapkan pada jenjang SMP, SMA, atau S1 jurusan biologi. Metode yang digunakan pada tahap 1 menentukan jenjang sekolah, penentuan footprint sekolah didasarkan pada isi media pembelajaran (content) yaitu pada augmented reality dengan menggunakan visual WIKU yaitu mata pelajaran yang menjelaskan tentang struktur morfologi pada Wijaya Kusuma bunga. Dari hasil pertimbangan tersebut ditentukan tiga jenjang sekolah yaitu SMP, SMA dan S1 jurusan Biologi sebagai sampel dari uji coba. Tahap 2 membuat angket, pembuatan angket sehingga dapat diketahui respon siswa-siswa, untuk menilai augmented reality menggunakan visual WIKU baik dari segi antarmuka aplikasi dan konten aplikasi yang ada. Kuesioner divalidasi kepada pihak-pihak yang berkompeten di bidangnya. Analisis data tahap 3, data hasil angket dianalisis baik secara kuantitatif maupun kualitatif, sehingga diperoleh jenjang sekolah mana yang masih menerapkan augmented reality dengan menggunakan WIKU visual ini. Dari hasil penelitian ini dapat disimpulkan bahwa tingkat pendidikan SMP yang memberikan nilai baik dengan bobot 4 pada augmented reality dengan menggunakan WIKU visual, artinya augmented reality dengan menggunakan visual wiku dapat diterapkan pada pendidikan SMP. Hasil data angket dianalisis baik secara kuantitatif maupun kualitatif, sehingga diperoleh jenjang sekolah mana yang masih menerapkan augmented reality dengan menggunakan WIKU visual ini. Dari hasil penelitian ini dapat disimpulkan bahwa tingkat pendidikan SMP yang memberikan nilai baik dengan bobot 4 pada augmented reality dengan menggunakan WIKU visual, artinya augmented reality dengan menggunakan visual wiku dapat diterapkan pada pendidikan SMP.

Authors:Yustika Ayu Sekartaji, Diana Hernawati, Vita Meylani Pages: 103 - 111 Abstract: Ethnozoological study is a study that examines the relationship between humans and animals in traditional studies. People's knowledge in relation to these animals has been passed down from generation to generation to become local wisdom. This ethnozoology includes the matter of raising animals, managing animals for medicine, food and customary and ritual activities, as well as the reciprocal relationship between humans and surrounding animals. The people of Kampung Naga are indigenous people located in Tasikmalaya who still adhere to the local wisdom they have today. Due to the absence of a study on ethnozoological studies in the Kampung Naga community, research was carried out on animal maintenance and control of rice pests which were included in the study of ethnozoological studies. The data collection techniques in this study were interview techniques and documentation with qualitative research methods. The results of the study found that the people of Kampung Naga have local wisdom regarding the control of agricultural pests, the main pests are brown planthopper, walang sangit, rats and birds as well as animal maintenance including chickens, goats, fish, guinea pigs and rabbits. This study aims to describe the study of ethnozoological studies of the people of Kampung Naga, Neglasari Village, Salawu District, Tasikmalaya Regency as a source of learning biology in the form of a booklet.ETNOZOOLOGI: STUDI KEARIFAN LOKAL MASYARAKAT ADAT KAMPUNG NAGA TASIKMALAYA PubDate: 2021-11-25 DOI: 10.25273/florea.v8i2.9504 Issue No:Vol. 8, No. 2 (2021)
