Abstract

Crocidolomia binotalis Z. is an important cabbage plant pest in Indonesia. Nevertheless, pest control strategies depend on synthetic pesticides, negatively impacting ecosystems.Therefore, developing an effective organic pesticide approach to controlling C. binotalis is necessary. This research aimed to test the effectiveness of goatweed flower extract (Ageratum conyzoides L.) in controlling pest C. binotalis. The research consisted of two sets of experiments with two methods: the stomach and contact poison. Each experimental set was arranged in a completely randomized design (CRD) with three replications. The treatments were six levels of extract concentration at 0%, 15%, 30%, 45%, 60%, and 75%. The results showed that the application of A. conyzoides flower extract using the stomach and contact poison methods significantly increased the percentage of larval mortality 24 hours after application (haa) and the percentage of total larval mortality. The flower extract treatment of A. conyzoides significantly reduced the percentage of leaf area eaten, increased larval mortality, inhibited pupation and imago emergency, and shortened the larval stage's duration. The percentage of larval mortality through contact poison was higher than stomach poison.

Abstract

Indonesian konjac (Amorphophallus muelleri Blume) naturally grows on forest under the shade of the trees. However, this crop has become an important commercial tuber crop due to the whay the  tuber crops, Indonesian konjac has been cultivated by employing the relatively high input in cultural practices, especially the use of fertilizer. NPK fertilizer has been commonly used to cultivate Indonesian konjac to produce high yield of corm. The present study was undertaken to evaluate the residual effect of NPK fertilizer on growth and corm yield of Indonesian konjac. Vertisol soil previously unfertilized (A), previously fertilized with 100 kg NPK/ha (B) and previously fertilized with 200 kg NPK/ha (C) were used to grow Indonesian konjac. The Indonesian konjac grown on each soil (A, B or C) was fertilized with 0 kg NPK/ha, 150 kg NPK/ha and 300 kg NPK/ha. Thus, the study used 9 treatments, and each treatment was replicated three times. All data obtained were analyzed by employing the standard deviation from 3 replicates. The results of the present study revealed that NPK fertilizer addition did not increase plant height, shoot diameter, shoor dry weight, corm diameter, corm thickness and corm fresh weight of Indonesian konjac grown on Vertisol soil previously unfertilized, previously fertilized with 100 kg NPK/ha or previously fertilized with 200 kg NPK/ha. Thus, the results of the present study suggest that Vertisol soil is fertile and addition of NPK fertilizer is not necessary to grow this kind of konjac.

Abstract

The purpose of this study was to investigate the different environmental factors that influence the growth, productivity, and quality results of harvest sorghum (Sorghum bicolor L.) as material food alternatives and materials raw bioethanol. The study consisted of 3 different treatments, where each treatment produced data to examine its effect on productivity, quality results. The experiment was designed using RAKF (factorial randomized block design) experimental design with one treatment factor, the usage of biofertilizer. The results show that liming at a dose of 2.5 tons/ha (Ca1) is sufficient to cultivate on acid soils with the red-yellow podzolic type and is more optimal if using a dosage of 5 tons per hectare depending on the results of soil analysis before planting. The best sugar quality is produced in the planting treatment during the dry season, with a total sugar value of about 14.5% and the highest reduction sugar of 2.4%. The addition of lime to acidic soil and the application of chemical and biofertileizers are crucial for optimal growth, enhancing both vegetative and generative development when applied in appropriate amounts. Furthermore, exploring the physiological mechanisms behind seasonal impacts on sugar content and assessing the economic viability of different planting seasons will provide valuable guidelines for farmers seeking to maximize food production and bioethanol raw materials.
Pengaruh Variasi Ukuran Bulbil terhadap Viabilitas dan Pertumbuhan Vegetatif Porang (Amorphophallus muelleri Blume) pada Tanah Masam Ulinuhayani, Muhammad; Singgih, Bambang; Nurhidayat, Setia Permana; Rusdi, Nurul; Triono, Budi

Abstract

Porang (Amorphophallus muelleri Blume) merupakan tanaman umbi-umbian yang berpotensi untuk memenuhi kebutuhan komoditas pangan. Jenis ini tumbuh optimal pada tanah humus berpasir dengan pH normal dan kaya akan unsur hara. Sementara, masalah utama kondisi sebagian besar tanah di Indonesia merupakan tanah masam yang kering dan miskin unsur hara. Bibit yang berasal dari umbi bulbil secara ekonomi dianggap menguntungkan karena lebih murah, efisien dan praktis. Penelitian ini bertujuan untuk mengetahui viabilitas dan pertumbuhan vegetatif porang dengan berbagai ukuran bulbil yang ditanam pada tanah masam yang telah diberi kapur. Rancangan percobaan menggunakan Rancangan Kelompok Teracak Lengkap (RKTL) dengan 3 ulangan. Perlakuan yang divariasikan adalah bulbil dengan diameter kecil 0,6 - 1,5 cm (1 gr), diameter sedang 1,6 - 2,5 cm (4 gr), dan diameter besar 2,6 - 3,5 cm (10 gr). Media semai berupa tanah yang diambil di sekitar lokasi penelitian dicampur dengan kapur dengan perbandingan tanah: kapur (1:10). Parameter yang diukur adalah viabilitas, pertumbuhan tinggi batang, dan diameter batang. Perhitungan viabilitas dilakukan pada 4 minggu setelah semai sedangkan tinggi dan diameter batang dilakukan pada 9 minggu setelah semai. Variasi ukuran bulbil tidak berpengaruh terhadap viabilitas tanaman porang, namun bulbil dengan ukuran besar cenderung memiliki viabilitas lebih tinggi mencapai nilai 100%. Perlakuan variasi ukuran bulbil berpengaruh nyata terhadap tinggi dan diameter batang (p<0,05). Umbi besar menghasilkan diameter tinggi dan lebar paling optimal yaitu tanaman kedua memiliki tinggi 62,27 cm dan lebar 1,6 cm sedangkan umbi kecil menghasilkan batang terendah yaitu tinggi 9,2 cm dengan lebar 0,27 cm dengan diameter.
