RAPD is one of the DNA markers that utilize the principle of Polymerase Chain Reaction (PCR) machine which can amplify specific DNA sequences in vitro. The primary selection is made to display the DNA band pattern which can be used to obtain polymorphism information. This study aims to determine the RAPD-PCR primer that can be used to differentiate accession of cinnamon bark in Jambi Province, Indonesia. RAPD-PCR primer selection was carried out by using 100 primers which produces a polymorphic DNA band. Ten primers were identified to produce polymorphic DNA bands for cinnamon bark DNA namely: OPE-6, OPE-20, OPH-7, OPH-14, OPH-19, OPM-2, OPM-5, OPM-6, OPM-16 and OPM-19.

One of the efforts to make efficient use of yard is by planting with plants that are used to meet the needs of themselves and the needs of others. In addition, to make efficient use of land and yard will be well maintained, beautiful and also increase household income. In Teratai village, Muara Bulian sub-district, there is agroindustry based on farmer group which has the healthy drink with the red ginger raw material. They produce these healthy drinks by using raw materials ordered from other regions. This makes agroindustry highly dependent on the supply of others to meet the needs of these raw materials. In this devotional activity carried out demonstration area on the farmyard yard where the Team Dedication as a companion. Through demonstration the farmers' area gets direct guidance from the Community Services Team, seeing and practicing every material given in accordance with the stages of plant development. In this way, it is expected to transfer knowledge and technology effectively from universities to the community. Thus, it is expected to increase the knowledge and skills of farmers in the cultivation of red ginger plants as yard plants, especially ginger farmers in the village of Teratai and generally red ginger farmers in Muara Jambi Regency.

Padi payo merupakan salah satu varietas padi lokal dari Kabupaten Kerinci Provinsi Jambi yang cukup populer disebabkan tekstur dan citarasa yang enak. Eksistensi padi payo semakin lama semakin terancam akibat pembangunan infrastruktur dan beralihnya pilihan petani ke varietas unggul modern. Penelitian ini bertujuan mengetahui diversitas genetik populasi padi payo di Kabupaten Kerinci berdasarkan marka morfologi. Penelitian bersifat non eksperimen, data diperoleh dari hasil survai atau karakterisasi langsung secara in situ. Penentuan sampel dilakukan secara Proportionate Stratified Random Sampling. Karakter yang diobservasi merupakan karakter morfologi yang diukur secara kualitatif dan kuantitatif dengan mengacu pada panduan yang dikeluarkan oleh Bioversity International, IRRI, dan WARDA, dengan sedikit modifikasi. Data yang diukur secara kuantitatif dianalisis dengan menggunakan parameter koefisien keragaman sedangkan data yang diukur secara kualitatif dianalisis dengan parameter indeks diversitas relatif (J). Diversitas genetik antar individu dalam populasi dianalisis dengan menggunakan analisis klaster yang ditampilkan dalam bentuk dendrogram. Hasil menunjukkan bahwa beberapa karakter morfologi yaitu jumlah anakan produktif, sudut daun bendera, kerontokan, jumlah gabah hampa, warna telinga daun, warna leher daun, permukaan daun, dan warna gabah, memperlihatkan variabilitas yang luas hingga sangat luas, sedangkan karakter lainnya sempit dan sangat sempit. Terdapat diversitas genetik yang luas dalam populasi padi payo di Kabupaten Kerinci. Tidak kurang dari 21 genotipe berbeda terdapat dalam populasi padi payo saat ini.

Penelitian ini bertujuan untuk mengetahui pengaruh interaksi antara genotip – genotip kedelai dengan pola tumpangsari, mendapatkan genotip-genotip kedelai yang beradaptasi baik pada pola tumpangsari antara kedelai dengan jagung. Penelitian ini dilaksanakan di Teaching and Research farm Fakultas Pertanian Universitas Jambi yang dilaksanakan dari bulan Desember 2015 sampai dengan bulan Maret 2016. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK), yang terdiri dari 2 faktor. Faktor pertama adalah genotip yang terdiri 4 genotip kedelai (g) yaitu g1 = 5–196–4–3, g2 = 5–196–9–3, g3 = 5–196–9–11 dan g4 = 5–196–9–12, dan faktor kedua adalah pola tanam (p) yang terdiri 3 pola tanam p1  = 1 Tanaman kedelai : 1 Tanaman jagung, p2  = 2 Tanaman kedelai : 1 tanaman jagung dan p3 = 3 Tanaman kedelai : 1 tanaman jagung. Masing-masing kombinasi perlakuan diulang dua kali sehingga terdapat  24 petak percobaan. Data hasil pengamatan dianalisis secara statistik dengan mengunakan sidik ragam dan kemudian dilanjutkan dengan DMRT ( Duncan Multiple Range Test) pada taraf α = 5%. Hasil penelitian menunjukkan terdapat interaksi antara genotip kedelai dengan pola tanam pada jumlah polong per tanaman dan jumlah polong berisi per tanaman. Perlakuan genotip berpengaruh nyata terhadap tinggi tanaman kedelai, jumlah polong pertanaman, jumlah polong berisi, produksi kedelai (ton/ha), Perlakuan pola tanam berpengaruh nyata terhadap jumlah polong per tanaman, jumlah polong berisi per tanaman, bobot 100 bji, hasil kedelai (ton/ha). Perlakuan terbaik pada pola tanam 2 kedelai: 1 jagung This study aims to determine the effect of the interaction between genotype - genotype soybean intercropping patterns, obtain soybean genotypes adapted to intercropping patterns between soybeans and corn. This research was conducted at Teaching and Research Farm of Faculty of Agriculture, Jambi University in December 2015 - March 2016. This study uses a randomized block design (RBD), which consists of two factors. The first factor is the genotype comprising four soybean genotypes (g) is g1 = 5-196-4-3, 5-196-9-3 = g2, g3 = 5-196-9-11 and g4 = 5-196-9 -12, and the second factor is the cropping pattern (p) comprising three cropping patterns p1 = 1 soybean plants: 1 plants of corn, soybean crops p2 = 2: 1 corn and soybean crops p3 = 3: 1 corn. Each combination treatment is repeated twice so there are 24 experimental plots. The data are statistically analyzed by using analysis of variance and then continued with Duncan Multiple (Duncan Multiple Range Test) at level α = 5%. The results shows that there is an interaction between the genotype of soybean cropping patterns in the number of pods per plant and number of pithy pods per plant. Treatment genotype significantly affected the height of soybean plants, pods cropping, pithy pods, soybean production (tons / ha), treatment cropping patterns significantly affect the number of pods per plant, number of pithy pods per plant, weight of 100 grains, soybean yield (tons /ha). The best treatment on soybean planting pattern is 2: 1
