Abstract

The objectives of the experiment were to (1) investigate the effect of seed imbibitions period on inducing somatic embryo of peanut varieties, (2) determine the best imbibitions period. The experiment was arranged in a completely randomized design with eight replicates. Each experimental unit consisted of culture bottles each of which contained five leaflet explants. Two varieties of peanut of var. Kancil and var. Singa were imbibed in water for 0, 20, 40, and 60 hours before sown aseptically on MS medium. Data were subjected to analysis of variance and if there was any significant F result (s), the means were separated using least significant difference at P? 0.05. Results of the experiment showed that: (1) Imbibitions period had significant effect on inducing somatic embryo of peanut varieties, (2) For var. Kancil, the best embryo somatic numbers and embryonic callus percentage were produced by 40 hours of imbibitions, while for var. Singa were produced by 20 hours imbibitions.  Key words: peanut, imbibitions period, MS medium, somatic embryo.

Abstract

Pengaruh Komposisi Media Tanam Terhadap Pertumbuhan Setek Empat Klon Ubi Kayu (Manihot Esculenta Crantz). Penelitian ini bertujuan untuk menentukan komposisi media tanam yang tepat untuk pertumbuhan setek ubi kayu, menentukan klon ubi kayu yang memiliki pertumbuhan terbaik dan mengetahui apakah respon setek ubi kayu terhadap komposisi media tanam ditentukan oleh klon yang digunakan.  Penelitian dilaksanakan di Rumah Kaca Fakultas Pertanian, Universitas Lampung dari bulan April 2020 sampai bulan Juni 2020.  Penelitian disusun secara faktorial dalam rancangan acak lengkap (RAL) dengan 3 ulangan. Faktor pertama adalah komposisi media (tanah+pasir+sekam padi dan tanah+pasir+kompos) dan faktor kedua adalah klon (UJ-3, UJ-5, BW1, Unila UK-1). Hasil penelitian menunjukkan (1) komposisi media menghasilkan pertumbuhan yang sama. (2) Klon memberikan respons yang sama terhadap komposisi media.

Abstract

Fertigasi merupakan metode memanfaatkan bio-slurry cair (pupuk organik). Sistem fertigasi membuat pemakaian bio-slurry cair dan air lebih efisien karena larutan nutrisi diberikan pada waktu, jumlah dan komposisi yang tepat.  Tujuan kegiatan ini adalah: 1. Petani dapat mengelola bio-slurry cair dan air dengan lebih efisien melalui aplikasi fertigasi berbahan bio-slurry cair; 2. Petani dapat membuat, dan memelihara aplikasi fertigasi berbahan bio-slurry cair. Metode untuk mencapai tujuan adalah ceramah/diskusi, pendampingan terjadwal, dan demplot (demontration plot).  Sasaran kegiatan ini adalah anggota Kelompok Tani Mekar Sari dan masyarakat di sekitar Desa Banyu Urip. Melalui penjelasan tentang aplikasi fertigasi berbahan bio-slurry cair petani dapat lebih memanfaatkan bio-slurry cair dalam budidaya sayuran secara serius dan berkelanjutan. Hasil kegiatan pengabdian menunjukkan pengetahuan dasar petani tentang aplikasi fertigasi berbahan bio-slurry cair meningkat dari 20% menjadi 80%.  Pengetahuan tentang manfaat aplikasi fertigasi berbahan bio-slurry cair meningkat dari 30% menjadi 85%. Pengetahuan tentang instalasi aplikasi fertigasi berbahan bio-slurry cair meningkat dari 37,5% menjadi 80%. Ketertarikan/preferensi aplikasi fertigasi berbahan bio-slurry cair meningkat dari 45% menjadi 90%. Dengan demikin, kegiatan ini secara umum meningkatkan pengetahuan petani tentang aplikasi fertigasi berbahan bio-slurry cair pada budidaya sayuran dari 34% menjadi 83,75%.

Abstract

The presence of pulp in cocoa seeds is known to inhibit seed germination and seedling growth. The conventional method of removing pulp from cocoa seeds is done mechanically by rubbing the seeds with rubbing ash. Conventional pulp removal has disadvantages, such as being less practical and potentially damaging the seed surface. Therefore, it is necessary to try chemically removing the pulp from cocoa seeds by soaking the seeds in a lime solution (CaCO3). This study aims to determine the effect of the duration of cocoa seed soaking in CaCO3 solution and different planting media compositions on seedling growth. The research was conducted from September to December 2021 at a plastic house in Labuhan Dalam Village, Tanjung Senang District, Bandar Lampung, and the Seed Laboratory, Faculty of Agriculture, University of Lampung, Gedong Meneng, Bandar Lampung. The study used a Completely Randomized Design (CRD) arranged in a factorial manner. The first factor was the duration of cocoa seed soaking in CaCO3 solution, consisting of no soaking, soaking for 30, 60, 120, and 240 minutes. The second factor was the planting media composition, consisting of a mixture of rice husk charcoal + manure, sand + manure, and sand + rice husk charcoal + manure. Each treatment combination was replicated three times, resulting in 45 experimental units. The observation data were analyzed using analysis of variance, and the mean differences were tested using the Least Significant Difference (LSD) test at the 5% level. The results of the study showed that the duration of cocoa seed soaking in CaCO3 solution had no effect on cocoa seedling growth. The planting media composition of sand + rice husk charcoal + manure had a significant effect on the best cocoa seedling growth compared to the planting media compositions of rice husk charcoal + manure and sand + manure. Soaking cocoa seeds in CaCO3 solution had no effect on cocoa seedling growth in different planting media. Keywords : Cocoa seeds, pulp, CaCO3, soaking, planting media
