Judul: Keragaan Sifat Morfologis dan Agronomis Calon Varietas Hibrida Cabai (Capsisum annuum L.) pada pertanaman di Lahan Petani Sukabumi.
Abstrak: Hot pepper (Capsicum annuum L.) is one of the important vegetable in Indonesia, but it’s production is still unoptimum. An alternative solution to increase hot pepper productivity is by developing and using superior hybrid varieties. The aims of this research were to describe morphological and agronomical characters of some potential hybrid varieties and to estimate their production. The experiment was conducted by using Randomized Block Design with one treatment (pepper’s genotype) and the blocks were prepared as triplicate. The result showed that there were diversity on morphological traits especially for the character of leave, stem, and habitus. There were also diversity in agronomical traits i.e. the number of fruits per plants, fruit weight per plant, the diameter of fruit, fruit length, and the number of seeds per fruit. Hybrid of LR x GD1 showed the highest number fruit per plant, fruit weight per plant, and plant height. Hybrid of GD2 x CD1 showed the highest value in diameter and length of fruit, and the number of seeds per fruit. Based on estimation of the productivity, LR x GD1 (9,50 ton/ha), CJ x CD1 (9,40 ton/ha), and GD2 x CD2 (8,02 ton/ha) are the potential hybrids with high production. LR x GD1 and CJ x CD1 have curly fruit type, whereas GD2 x CD2 has big fruit type. They have erect plant growth habit.

Judul: Pewarisan Karakter Morfologis dan Agronomis pada Persilangan Antara Cabai Besar dan Cabai Keriting (Capsicum annuum L.)
Abstrak: Pepper productivity of Indonesia is 6.3 ton/ha in 2008, which could be increased up to 12-20 ton/ha. One of strategy to improve productivity is development of superior variety via hybridization and selection process that need information of inheritance pattern and heritability value. This research studied the pattern of inheritance of morphologic and agronomic traits in the crossing of double haploid of big pepper (Tit-Super) and curly pepper (Laris), F1, and F2 population. Morphologic traits that included main stem color, node color, flower position, leaf color, leaf shape, and plant growth habit were segregating in F2 TS x LR population. Each trait was controlled by at least two genes. Agronomic traits that included 30 days after planting height, days to flowering, days to fruiting, plant height, main stem length, fruit diameter, fruit weight, and number of seed per unit fruit were segregating with high variability. It was indicated that the traits were controlled by poly genes. Based on agronomic trait: fruit per plant, fruit diameter, and fruit weight which have higher viability and heritability value (>82.9%) could be selected ten individual from 99 plants with high index selection from F2 TS x LR population

Judul: Pengamanan Internet of Things (IoT) untuk Tanda Tangan Digital Menggunakan Algoritme Elgamal Signature Scheme
Abstrak: Internet of Things (IoT) memungkinkan suatu objek menghasilkan data dan bertukar data. Pengaplikasian IoT menggunakan mikrokontroler seperti Arduino masih belum terdapat keamanan data di dalamnya. Selain itu, Arduino memiliki kapabilitas komputasi terbatas. Oleh karena itu, perlu diterapkan kriptografi dengan algoritme yang memiliki komputasi rendah pada Arduino untuk menjaga keamanan data. Keamanan data terutama pada keaslian asal data, dengan melakukan tanda tangan digital. Penerapan tanda tangan digital dapat dilakukan salah satu contohnya dengan algoritme Elgamal signature scheme. Penerapan tanda tangan digital menggunakan algoritme Elgamal signature scheme berhasil diterapkan pada perangkat Arduino Uno untuk melakukan tanda tangan digital dan verifikasi. Kinerja algoritme Elgamal signature scheme dilihat dari analisis waktu eksekusi dan analisis keamanan algoritme. Waktu eksekusi proses tanda tangan digital membutuhkan waktu lebih lama dibandingkan dengan waktu eksekusi proses verifikasi. Algoritme Elgamal signature scheme membutuhkan waktu dua kali lebih lama karena banyaknya perhitungan sistematis pada perangkat Arduino Uno. Proses verifikasi terbukti gagal jika ada perubahan data dan pasangan tanda tangan digital.
