Abstract

The Rutaceae famili is a citrus plant that is spread throughout Indonesia. These plants are rich with vitamin C, folate and fiber. Rutaceae members have not been well identified until now, especially in the Sriwijaya Botanical Gardens. This research aims to determine various species of plants in the Rutaceae family in the Sriwijaya Botanical Gardens. This research is a qualitative descriptive study. Data collection was carried out by direct exploring inside the Sriwijaya Botanical Gardens. The results found five species of the Rutaceae family, such as jeruk nipis or lime (Citrus aurantiifolia), jeruk kunci or calamansi (Citrus microcarpa), gongseng or orange berry (Glycosmis pentaphylla), sampang or euodia lunu-ankenda (Melicope lunu-ankenda) and kemuning or orange jasmine (Murraya paniculata).

Abstract

The duku plant (Lansium domesticum Corr) is a plant that is widely distributed in tropical regions such as Indonesia. One of the famous plants in Indonesia is duku Komering. Duku has a very sweet taste with proven production increasing every year. So it is necessary to cultivate duku using tissue culture techniques. The use of tissue culture techniques is able to produce seedlings in large quantities in a short time. This research aims to see the response of stem explants from plantlets. The research was carried out in the Tissue Culture room, Integrated Laboratory, Raden Fatah State Islamic University, Palembang for 49 days after induction (DAI). The type of research used is qualitative descriptive research and experimental methods with a completely randomized research design (CRD). This research used several varying concentrations of kinetin, including 0 ppm, 1 ppm, 2 ppm, 3 ppm and 4 ppm. on stem explants (caulis) from duku plantlets (Lansium domesticum Corr.). The results showed that there was no growth response to the administration of various concentrations of kinetin during the observation

Abstract

The stevia plant (Stevia rebaudiana B.) is found in the United States, and is often used as a mixture in drinks. In Indonesia, cultivation of stevia began in 1977 in West Java and Central Java. The natural sweetener content with low calories makes stevia a solution for diabetes sufferers. Conventional cultivation takes a long time and depends on soil conditions, climate and variety. Tissue culture is used for plant propagation in a short time, free of pests and diseases, and does not depend on the season. Growth Regulators (ZPT) such as kinetin are used to accelerate shoot growth. The tissue culture media used is Murashige Skoog (MS). This study aims to examine the effect of kinetin on shoot induction in stevia explants through tissue culture, with explants in the form of leaf petioles. This study used a Completely Randomized Design (CRD) with kinetin concentrations of 1 ppm, 2 ppm, 3 ppm and 4 ppm. The results of the research showed that all kinetin treatments on leaf petiole mother explants were able to form shoots with an average percentage of 100%. But it didn't show any influence.

Abstract

Model pembelajaran kooperatif tipe student team achievement division pada keterampilan proses sains peserta didik diarahkan untuk menemukan sendiri berbagai fakta, membangun konsep, motivasi dan kerjasama dalam kelompok, memudahkan pemecahan masalah baik dalam pembelajaran sains maupun sosial. Penelitian bertujuan untuk menganalisis pengaruh keterampilan proses sains peserta didik melalui model pembelajaran kooperatif tipe student team achievement division materi struktur dan fungsi tumbuhan. Metode penelitian menggunakan metode kuantitatif dengan desain penelitian quasi eksperimen. Populasi penelitian ini adalah seluruh peserta didik kelas VIII SMP Negeri 1 Muaradua Kisam sebanyak 98 orang. Sampel penelitian VIII.1 sebagai kelas kontrol dan kelas VIII.2 sebagai kelas eksperimen berjumlah 50 peserta didik.Teknik sampel menggunakan teknik purposive sampling. Teknik pengumpulan data menggunakan tes tertulis, wawancara, observasi dan dokumentasi. Teknik analisis data penelitian berupa uji normalitas dengan uji shapiro-wilk, uji homogenitas, uji hipotesis dengan uji independent t test, serta uji N-gain. Hasil penelitian menunjukkan bahwa penerapan model pembelajaran kooperatif tipe STAD dapat meningkat secara signifikan terhadap keterampilan proses sains peserta didik pada materi struktur dan fungsi tumbuhan dibuktikan dengan diperoleh nilai signifikansi sebesar 0,00 berarti H1 diterima dan H0 ditolak. Maka dapat disimpulkan terdapat pengaruh dari penerapan model pembelajaran kooperatif tipe STAD terhadap keterampilan proses sains peserta didik pada materi struktur dan fungsi tumbuhan.

Abstract

Vanilla (Vanilla planifolia Andrews) is a plantation plant that is used for its fruit. Indonesia is one of the countries that exports vanilla and has climate factors that support increasing vanilla production to meet global demand, One of the efforts that can be made in vanilla propagation is through plant tissue culture. This research aims to induce calluses. This study used a Random Design using stem explants and several different hormone concentrations, namely: 0.0 ppm NAA and 0.0 ppm Kinetin, 1.0 ppm NAA and 0.5 ppm Kinetin, 1.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 0.5 ppm Kinetin, 2.0 ppm NAA and 1.0 ppm Kinetin, 2.0 ppm NAA and 2.0 ppm Kinetin. There was an effect on the administration of NAA and Kinetin on callus induction in the explants of the vanilla plant (Vanilla planifolia Andrews). It is based on the Anova one-way Hypothesis Test with a significance value of 0.000 (Asymp. Sig <0.05) then Ho was rejected and H1 was accepted. The optimal concentration to induce callus in stem explants is the administration of 1.0 ppm NAA + 0.5 ppm Kinetin with an average callus growth rate of 7 HST and a 100% callus growth percentage of explants.   Keywords: Vanilla, induction, callus, tissue culture, hormones
