Rubrum) Through In Vitro Culture, supervised by Luthfi Aziz Mahmud Siregar and Emmy Harso Kardhinata. This research aims to explore the combination of BAP and NAA with a specific concentration on MS medium toward micropropagation of local red ginger cultivars (Zingiber officinale var. Rubrum) through in vitro culture. This research was conducted at the Tissue Culture Laboratory of the ALIFA Agricultural Research Center (ALIFA-ARC) Medan from September 2021-February 2022. This research used a completely randomized design (CRD) with two treatment factors: plant growth regulators (without plant growth regulators, 2 mg/l BAP + 0.5 mg/l NAA, 3 mg/l BAP + 1 mg/l NAA, 3 mg/l BAP + 0.5 mg/l NAA and 5 mg/l BAP + 0.5 mg/l NAA) and local cultivars (local cultivar 1 and local cultivar 2). The results showed that at the stage of shoot induction, the treatment plant growth regulators had a significant effect on the number of shoots, color of shoots and length of shoots, but not a significant effect on the number of roots and length of roots. The treatment of local cultivars had no significant effect on each observation parameter. The interaction of the two treatments significantly affected the color of shoots. The combination of 3 mg/l BAP + 1 mg/l NAA responded to the number of shoots and length of shoots.Timoria Novalinda, 2022. Pengaruh Zat Pengatur Tumbuh Terhadap Mikropropagasi Kultivar Jahe Merah Lokal (Zingiber officinale var. Rubrum) Melalui Kultur In Vitro, dibimbing oleh Luthfi Aziz Mahmud Siregar dan Emmy Harso Kardhinata. Penelitian ini bertujuan untuk menjajaki kombinasi BAP dan NAA dengan konsentrasi tertentu pada medium MS terhadap mikropropagasi kultivar jahe merah lokal (Zingiber officinale var. Rubrum) melalui kultur in vitro. Penelitian ini dilaksanakan di Laboratorium Kultur Jaringan ALIFA Agricultural Research Center (ALIFA-ARC) Medan pada September 2021-Februari 2022. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktor perlakuan: zat pengatur tumbuh (tanpa zat pengatur tumbuh, 2 mg/l BAP + 0.5 mg/l NAA, 3 mg/l BAP + 1 mg/l NAA, 3 mg/l BAP + 0.5 mg/l NAA dan 5 mg/l BAP + 0.5 mg/l NAA) dan kultivar lokal (kultivar lokal 1 dan kultivar lokal 2). Hasil penelitian menunjukkan bahwa pada tahap induksi tunas, perlakuan zat pengatur tumbuh berpengaruh nyata terhadap jumlah tunas, warna tunas dan panjang tunas, akan tetapi berpengaruh tidak nyata terhadap jumlah akar dan panjang akar. Perlakuan kultivar lokal berpengaruh tidak nyata pada setiap parameter pengamatan. Interaksi kedua perlakuan berpengaruh nyata terhadap warna tunas. Kombinasi 3 mg/l BAP + 1 mg/l NAA memberikan respon pada jumlah tunas dan panjang tunas.76 halamanSkripsi Sarjan

The purpose of this study was to determine the maternal effect on the inheritance of maize traits through a reciprocal cross test between glutinuous corn (Zea mays L. var. URI) and sweet corn (Zea mays L. var. bonanza Now). This research was conducted on Jalan Sei Brantas, Medan with an altitude of ± 32 meters. This research was conducted from October 2020 to January 2021. The experimental design used was Reciprocal Cross, namely planting and observing each individual plant of the F1 generation. Crosses were carried out between the female elders of sweet corn and the male elders of sweet corn (F1), the male elders of sweet corn and the female elders of glutionuous corn (F1R) in 8 plots where each plot was planted with 4 plants. The total number of plants is 128 plants, with a sample of 1 plant per plot in the total sample is 32 samples. Based on the data obtained from the experiment, a t-test was performed at the 5% level and chi square test.The results showed that the percentage of crossing between sweet corn and glutinuous corn was 94%. Qualitative factors that affect the cross, namely the shape of the seeds from the crosses are round, while the color of the seeds from the dominant cross is yellow. The quantitative factor affected by the cross was significantly difference in the results on the the length of the seedless cobs, the diameter of the seedless cobs and weight of 100 seeds However, there was no significant difference in the parameters of the weight of the dry cobs.Muhammad Amri Yusra Simatupang, 2021 dengan judul penelitian “Uji Persilangan Resiprokal Jagung Pulut (Zea mays L. var.

Emmy Harso Kardhinata, M.Sc and Luthfi Aziz Mahmud Siregar, SP., M.Sc., Ph.D. This study aims to analyze the morphological and agronomic characters of cassava plants in Serdang Bedagai Regency, North Sumatra. The research was carried out on the land of Silau Rakyat Village, Sei Rampah District, Serdang Bedagai Regency, North Sumatra, Indonesia (± 11 masl) from July 2020 to February 2021. The description of the morphological character analysis was carried out based on Fukuda et al. (2004) and analysis of agronomic characters using a randomized block design of one factor, namely the cassava genotype obtained in Sei Rampah District. From the results of the study obtained 10 genotypes of cassava with various local names depending on the area where the plant is found, namely G1 (Malaysia), G2 (Klanting Merah), G3 (Genderuwo Hitam), G4 (Bread), G5 (Keling), G6 ( Sawit Gading), G7 (Genderuwo Merah), G8 (Lampung), G9 (Simerah) and G10 (Klanting Putih). Each genotype shows a distinctive character that can distinguish it from other genotypes, including the character color of shoot leaves, color of old leaves, young stem color and old stem color. Analysis of agronomic characters showed no significant difference among genotypes in the number of cassava/tree. The highest cassava length was in G7 and G3, and the lowest was in G4. The average diameter of cassava was almost the same for all genotypes , as well as the average weight of cassava per tree except for genotypes G5, G4 and G1 which had lower cassava weight per tree compared to other genotypes.M.
