Abstract

The learning process in high schools in West Papua tends to focus on students? cognitive enhancement and ignore the aspect skill. School is the frontline to develop students? skills. Metacognitive and process skills are the two skills needed by the students, and both should be trained and developed. These two skills help students to implement an investigation process in which the investigation process can be well utilized using inquiry-based learning. This study aims to find out the differences in metacognitive and process skills between students treated with inquiry-based learning and those who are taught using conventional learning. This experimental study was carried out at Grade X of senior high school students of SMA Negeri 1 Manokwari. The result reveals a significant metacognitive skill of 0.000 < ? 0.05, and science process skill of 0.001 < ? 0.05 of students who were taught using the inquiry-based learning more than those who were taught using the conventional learning. It can be concluded that there is a significant improvement in students? metacognitive and process skills for those who are taught using inquiry-based learning compared to those who are taught using conventional learning. Therefore, inquiry-based learning has the potential to appropriately train students? metacognitive and science process skill.

Abstract

A research was conducted to study total nitrogen, available phosphorus in soil and K-dd of soil under drought stress condition during tasseling until seed filling periods to inoculation with Azospirillum sp. and arbuscular mycorrhizal fungi (AMF) on Inceptisols. Two experiments were carried out in green house, using randomized block design arranged in factorial pattern. In pot experiment, two factors were assigned, i.e. inoculation with Azospirillum(0, 0.5, 1.0, 1.5 mL pot-1) and inoculation AMF (0, 12.5, 25.0, 37.50 g pot-1). Results of experiments showed that application AMF and Azospirillum sp. on certain dosage increased total nitrogen and available P of soil. However, inoculation Azospirillum, sp. and FMA didnt effect to K-dd of soil.

Abstract

This research is a quantitative descriptive study with a pre-experimental design which is intended to increase student learning activities through the implementation of guided inquiry-based learning on the structure and function of plant tissue materials. This research was conducted at SMP Negeri 12 Gorontalo class VIII for 4 meetings. The target of this research is students of class VIII-2 SMP Negeri 12 Gorontalo with a total of 28 students, Odd Semester in the 2019/2020 Academic Year. Student activities are measured through student activity observation sheets, then analyzed, grouped and presented through tables. The results of this study indicate that the implementation of guided inquiry-based learning tools can improve student learning activities on the structure and function of plant tissue in class VIII-2 of SMP Negeri 12 Gorontalo. The increase in student learning activities can be seen from the aspects observed at each meeting, namely meeting 1 the highest score in aspect 1 reaches a percentage value of 100, the lowest score in aspects 2 and 8 reaches a percentage value of 66. Meeting 2 the highest scores in aspects 1 and 4 reach a value percentage 95, the lowest score in aspect 2 with a percentage value of 76. Meeting 3 the highest values in aspects 1, 4 and 5 reached a percentage value of 100, the lowest value was in aspect 10 with a percentage value of 78. The meeting of 4 highest scores was in aspects 1, 3, 4 and 5 reaches a percentage value of 100, the lowest value in aspect 11 with a percentage value of 81.

Abstract

Plants that undergo drought stress perform a physiological response such as accumulation of proline in the leaves and increased content abscisic acid. A research was conducted to study proline and abscisic acid (ABA) content on drought-stressed corn plant with Azospirillum sp. and arbuscular mycorrhizae fungi (AMF) inoculated at inceptisol soil from Bogor, West Java. The experiments were carried out in a green house from June up to September 2003, using a factorial randomized block design. In pot experiments, two factors were assigned, i.e. inoculation with Azospirillum (0, 0.50, 1.00, 1.50 ml/pot) and inoculation with AMF Glomus manihotis (0, 12.50, 25.00, 37.50 g/pot). The plants were observed during tasseling up to seed filling periods. Results of experiments showed that the interaction between Azospirillum sp. and AMF was synergistically increased proline, however it decreased ABA. Key words: Azospirillum sp., Arbuscular Mycorrhizae fungi, Corn, drought, proline, abscisic acid (ABA)

Abstract

Salah satu produk turunan dari tanaman kelapa (Cocos nucifera, L.) adalah minyak kelapa. Kualitas minyak kelapa yang baik memiliki nilai bilangan peroksida dan kadar asam lemak bebas yang rendah. Penelitian ini bertujuan untuk menganalisis bilangan peroksida dan asam lemak bebas pada virgin coconut oil (VCO) hasil fermentasi yang disuplementasi dengan kunyit dan menentukan konsentrasi optimum penambahan kunyit untuk mendapatkan VCO kualitas baik. Penelitian ini merupakan penelitian eksperimen dengan mengunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan lima kali pengulangan. Perlakuan yang digunakan adalah variasi volume penambahan kunyit (0; 50; 100 dan 150 mL). Metode titrasi digunakan untuk menganalisis bilangan peroksida dan kadar asam lemak. Data nilai bilangan peroksida dan asam lemak bebas dianalisis secara deskriptif naratif dan analisis statistik menggunakan uji Fisher (F) dan uji lanjut dengan uji Beda Nyata Terkecil (BNT). Hasil Penelitian menunjukkan bahwa penambahan kunyit dapat menurunkan bilangan peroksida dan asam lemak bebas pada VCO hasil fermentasi. Bilangan perosida terukur dengan penambahan kunyit sebanyak 0; 50; 100 dan 150 mL berturut-turut adalah 3.44; 2.56; 1.96; dan 1.68 meq/kg, sedangkan kadar asam lemak bebas terukur berturut-turut sebesar 0.5; 0.40; 0.34; dan 0.28 %. Sehingga dapat disimpulkan bahwa penambahan kunyit pada VCO hasil fermentasi dapat meningkatkan kualitas minyaknya. Semakin besar volume kunyit yang ditambahkan maka nilai bilangan peroksida dan kadar asam lemak bebas semakin rendah.

Abstract

The purpose of this qualitative descriptive study was to find out the types of pathogenic fungi that caused rotten cacao fruits based on morphological characteristics in Tumba village. Fungi isolation was performed by employing the moist chamber method with the PDA medium. Moreover, the identification of pathogenic fungal isolates followed the morphological characteristics mentioned earlier. The results showed that four fungal isolates contributed to the rotting of cacao fruits in the site area. Fungal isolate Tumba 1 (T1) had morphological characteristics of a white colony with smooth surface, and oval sporangium with a bulge on its tip; fungal isolate Tumba 2 (T2) consisted of morphological characteristics of a white colony with a pink circle in the middle, and having a sickle-shaped and oval macroconidia; fungal isolate Tumba 3 (T3) comprised morphological characteristics of a dark black colony with irregular shape, uneven edge, and having a long conidiophore with a big conidial head; fungal isolate Tumba 4 (T4) had morphological characteristics of a black colony with a white circle in the middle, uneven edge, and having a tube-shaped conidium. As based on the morphological characteristics, it was assumed that the four fungal isolates causing the rotten cacao fruit were similar to the types of fungi, i.e., Phytopthora palmivora, Fusarium sp, Aspergilus niger, and Gloeosprorium sp.

Abstract

Salah satu sindrom kelainan metabolik pada manusia adalah Diabetes militus. Penyakit ini bisa diatasi dengan pengobatan alami dengan memanfaatkan tumbuhan. Salah satunya adalah tumbuhan suruhan (Peperomia pellucida (L.) Kunth, yang dapat diolah menjadi Teh herbal. Tujuan dari review ini adalah untuk menelusuri produk alami berupa senyawa bioaktif, proksimat dan potensi tumbuhan suruhan sebagai antidiabetes. Metode yang digunakan yaitu studi pustaka dengan mengumpulkan artikel dalam bentuk data primer berupa artikel jurnal nasional maupun jurnal internasional 10 tahun terakhir (2010-2020) dari database elektronik. Berdasarkan hasil review diperoleh bahwa tumbuhan Suruhan mengandung senyawa bioaktif seperti alkaloid, flavonoid, tanin yang dapat menghambat kerja enzim α-glukosidase melalui subtitusi pada cincin β dan melalui ikatan hidroksilasi. Tanin juga dapat menurunkan glukosa darah melalui penghambatan kerja enzim α-glukosidase yang dapat menunda penyerapan glukosa setelah makan, dengan cara memperpanjang waktu cerna karbohidrat, sehingga laju absorbsi glukosa menurun.
