“…Informasi penting tersebut berguna untuk mempersingkat waktu seleksi. Korelasi merupakan metode dalam menentukan keeratan satu karakter dengan karakter lainnya (Bechere et al, 2014;Maftuchah et al, 2015). Secara genetik, korelasi antarkarakter dapat terjadi karena adanya fenomena pleiotropi dan linkage.…”

ABSTRAKKeberhasilan seleksi tanaman melalui pemuliaan ditentukan oleh keragaman genetik, nilai heritabilitas, korelasi antara karakter agronomi dan hasil panen. Penelitian bertujuan untuk mengetahui keragaman genetik, heritabilitas, dan pengaruh karakter agronomi terhadap hasil jagung hibrida. Percobaan dilaksanakan pada Februari-Mei 2016 di Kabupaten Grobogan, Jawa Tengah. Perlakuan terdiri atas 12 genotipe jagung hibrida, menggunakan rancangan acak kelompok dengan tiga ulangan. Karakter yang diamati adalah tinggi tanaman, tinggi letak tongkol, jumlah tongkol panen, bobot kupasan basah, rendemen, kadar air panen, bobot 100 biji, panjang tongkol, diameter tongkol, jumlah baris per tongkol, jumlah biji per baris, dan hasil panen biji. Hasil penelitian menunjukkan tingginya keragaman genetik karakter agronomi jagung hibrida, kecuali diameter tongkol. Hampir semua nilai heritabilitas komponen hasil termasuk tinggi, kecuali bobot tongkol panen dan diameter tongkol. Secara genotipik, pengaruh langsung karakter tinggi tanaman, tinggi letak tongkol, dan panjang tongkol terhadap hasil biji tergolong tinggi. Secara fenotipik hanya bobot tongkol panen yang berpengaruh langsung terhadap hasil biji.Kata kunci: jagung, hibrida, keragaman genetik, korelasi, heritabilitas ABSTRACTThe success of selection in plant breeding program is determined by genetic variabilities, heritability values and the correlation between agronomic characters and yield. The study aims to determine the genetic variability, heritability and the effec of agronomic characters to grain yield. The experiment was conducted in February to May 2016 in Grobogan, Central Java. The experiment consists of twelve genotypes of maize hybrids, arranged in a randomized block design with three replications. The characters observed were plant height, ear height, number of harvested ear, shelling percentage, moisture content of grain harvested, weight of 100 grains, ear length, ear diameter, number of rows per ear, number of seeds per row per ear, and grain yields. The results showed that the genetic variability of agronomic characters was broad, except ear diameter. Almost all of the heritability values of yield components were high, except harvested ear weight and ear diameter. The characters of plant height, ear height and as the genotypic gave high of a direct effect on the yield higher, while direct effect of the phenotypic character of ear hairves on grain yield are higher.

The decline in chili commodity production is influenced by various factors, including climate anomalies, less than optimal cultivation techniques, decreasing land quality, and pest attacks. Kabandungan District, as one of the chili production centers, can be used as a reference for studying the presence and intensity of chili pest attacks in general. Information about pest attacks can be used as a basis for control that can be applied in any location with similar characteristics. This research was conducted in Kabandungan District, Sukabumi Regency, West Java Province, Indonesia. This research was carried out from November 2021 to March 2022. The number of chili plants observed was 930 plants which were divided into 61 observation points spread across 6 villages, including Cianaga, Cihamerang, Cipeuteuy, Kabandungan, Mekarjaya, and Tugubandung Villages. The chili plants observed consisted of the local variety of cayenne pepper (CMR), cayenne red chili (CMR), curly red chili (CMK) variety TM 999, Darmais F1 large red chili (CMB), curly red chili (CMK), and chili curly red (CMK) OR Twist 42. The results of the study stated that the incidence of pest attacks was dominated by S. Litura attacks 26.40%, and Colletotrichum capsici 25.60% in the vegetative phase, as well as S. Litura 27.21%, and Gemini Virus 47.35% in the generative phase. S. litura attacks are reported to dominate all villages in Kabandungan District, while Mekarjaya Village is dominated by mites.

“…Hal ini dikarenakan proses hidrolisis trigliserida menjadi digliserida akan terus berlanjut membentuk asam lemak bebas yang membentuk sabun dan emulsi apabila bereaksi dengan katalis basa pada saat proses transesterifikasi. Ketika sabun dan emulsi terbentuk terlalu banyak akan menyulitkan saat proses pencucian biodiesel sehingga menurunkan rendemen [14] (Shahla et al, 2010).…”

Jarak pagar (Jatropha curcas L.) merupakan salah satu komoditi perkebunan tropis yang memiliki potensi sebagai pengganti bahan bakar minyak. Biji jarak pagar mengandung kadar minyak cukup tinggi dan sangat potensial sebagai bahan baku biodiesel. Kegiatan penelitian ini bertujuan mendapatkan informasi tentang tingkat produksi biji, kualitas crude jatropha oil dan biodiesel J.curcas Linn. sebagai sumber biofuels. Penelitian dilaksanakan di Desa Kedung Pengaron Pasuruan dan Laboratorium Teknologi Minyak Nabati Universitas Muhammadiayh Malang. Penelitian menggunakan Rancangan Acak Kelompok empat ulangan. Hasil pengamatan menunjukkan bahwa genotip J.curcas berpengaruh secara signifikan terhadap rerata jumlah buah per tanaman, jumlah biji per tanaman, berat kering biji per tanaman dan kadar minyak biji. Jumlah buah per tanaman dan berat kering biji per tanaman yang dihasilkan genotip JCUMM (JCUMM-5, JCUMM-6, JCUMM-7, JCUMM-18) lebih tinggi daripada kontrol IP3A dan IP3P. Jumlah biji per tanaman berkisar 91,3 (IP3P) hingga 236,6 (JCUMM-5). Berat kering 100 biji dari berbagai genotip J.curcas berkisar antara 64,1 g (JCUMM-6) hingga 69,7 g (JCUMM-5) sedangkan kadar minyak biji berkisar antara 39,5% (JCUMM-6) hingga 57,7% (JCUMM-7). Hasil uji esterifikasi menunjukkan hasil Free Fatty Acid dari crude jatropha oil berkisar antara 0,2% (JCUMM-18) hingga 1,97% (IP3A). Seluruh genotip memiliki kadar FFA kurang dari 2% sehingga masih layak dipergunakan sebagai bahan biodiesel. Nilai bilangan asam yang diperoleh antara 2,9 mg-KOH/g (JCUMM-6) hingga 6,40 mg-KOH/g (IP3A). Sedangkan bilangan Iodine diperoleh hasil antara 94,5 g I2/100g (JCUMM-5) hingga 102,4 g I2/100g (JCUMM-6)
