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: Yield Performance Evaluation of Hybrid and Non Hybrid Lines of Chili Pepper (Capsicum annuum L.) for New Variety Release
Abstrak: Cabai (Capsicum annuum L.) merupakan komoditas hortikultura yang bernilai ekonomi dan konsumsi yang tinggi, sehingga perlu dukungan ketersediaan varietas unggul dengan meningkatkan upaya pelepasan varietas atas kandidat varietas hasil pemuliaan tanaman. Penelitian ini bertujuan untuk mengevaluasi daya hasil galur hibrida dan non hibrida cabai besar IPB serta mengidentifikasi keunggulan galur uji cabai besar IPB yang akan dilepas menjadi varietas unggul baru. Penelitian ini dilaksanakan pada bulan September 2021 – Februari 2022 di Kebun Percobaan Leuwikopo IPB dan Laboratorium Pemuliaan Tanaman IPB. Rancangan percobaan yang digunakan adalah Rancangan Kelompok Lengkap Teracak (RKLT) faktor tunggal dengan genotipe cabai sebagai perlakuan. Perlakuan genotipe terdiri dari 10 genotipe cabai yang terdiri dari 1 galur uji hibrida, 2 galur uji non hibrida, 5 varietas pembanding hibrida, dan 2 varietas pembanding non hibrida. Setiap genotipe diulang sebanyak tiga kali sehingga terdapat 30 satuan percobaan. Hasil penelitian menunjukkan bahwa galur uji hibrida (F1.074005) maupun non hibrida (F12.120005 dan F8.074136) memiliki keunggulan seperti umur berbunga dan umur panen tergolong genjah (21,67-23,67 HST dan 66,3-68 HST), penampilan buah yang termasuk ke dalam mutu I SNI, bobot per buah tinggi (6,73 – 10,96 g), jumlah buah per tanaman banyak (78 – 129 buah), dan persentase hidup tinggi (88,33 – 96,67 %). Hasil uji korelasi menunjukkan bahwa potensi hasil tanaman berkorelasi sedang dengan karakter panjang daun, ketebalan buah, bobot per buah, jumlah buah per tanaman, bobot buah per tanaman, produktivitas, dan persentase hidup tanaman. Galur hibrida F1.074005, dan dua galur non hibrida F12.120005 dan F8.074136 direkomendasikan untuk dilepas., Chili (Capsicum annuum L.) is a horticultural commodity that has high economic value and consumption, so it is important to support the availability of high-yielding varieties by increasing efforts to release candidate varieties generated through plant breeding. This study aims to evaluate the yield of hybrid and non-hybrid test lines of chili pepper IPB and identify the advantages of test lines of chili pepper IPB which will be released into new high yielding varieties. This research was carried out in September 2021 – February 2022 at the Leuwikopo Experimental Garden of IPB and the Plant Breeding Laboratory of IPB. The experimental design applied a single factor Randomized Complete Block Design (RCBD) with chili genotype as the treatment. The genotype treatment consisted of 10 chili genotypes consisting of 1 hybrid test line, 2 non-hybrid test lines, 5 hybrid comparison varieties, and 2 non-hybrid comparison varieties. Each genotype was repeated three times so that there were 30 experimental units. The results showed that the hybrid test lines (F1.074005) and non-hybrid (F12.120005 and F8.074136) had such as flowering age and early harvesting age (21.67-23.67 DAP and 66.3-68 DAP), fruit appearance which is included in SNI I quality, high weight per fruit (6.73 – 10.96 g), large number of fruit per plant (78 – 129 fruit), and high proportion of living plant (88.33 – 96.67 %). The results of the correlation test showed that the potential yield of plants was moderately correlated with the characters of leaf length, fruit thickness, weight per fruit, number of fruit per plant, fruit weight per plant, productivity, and percentage of plant life.

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.
