The objective of this research was to study the effect of bokashi livestock on the growth and yield of tomatoes. The experiment was conducted in Bandar Lampung from October 2009 until February 2010. The experimental design was randomized complete block design with 3 replications. The treatments were: control; inorganic fertilizers at a recommended rate of (kg ha-1) 135 N, 75 P2O5, and 110 K2O (RR); chicken manure bokashi + RR; chicken manure bokashi + 50% RR; cow manure bokashi + RR; cow manure bokashi + 50% RR; sheep manure bokashi + RR; sheep manure bokashi + 50% RR; horse manure bokashi + RR; horse manure bokashi + 50% RR. Each bokashi treatment was applied at the rate of 20 ton ha-1. The result of experiment showed that chicken manure bokashi was the best among bokashi livestock. The application of 50% RR combined with chicken, cow, sheep or horse manure bokashi gave a higher yield than treatment with inorganic fertilizer at recommended rates. These results demostrated that the application of bokashi livestock could potentially reduce the use of inorganic fertilizers while maintaining higher yield.

This study aimed to determine the effects of chicken compost and KCl fertilizer application on the growth, yield, post-harvest quality of sweet corn (Zea mays L. var. saccharata), soil respiration and microbial population. The research was arranged according to a Factorial Random-Block Design consisting of two factors and three replications. The first factor was the dose of chicken compost (0 and 15 t/ha) and the second the dose of KCl fertilizer (0, 50, 100 and 150 kg/ha). The results showed that chicken compost stimulated the growth, yield, postharvest quality of sweet corn, respiration, and microbial activity of soil. KCl fertilizer increased SPAD values linearly and quadratically chlorophyll pigment, β-carotene, yield components, and yield. KCl fertilizer did not affect soil respiration, fungi, or bacteria populations. The use of chicken compost reduced the need for KCl fertilization by 25%. Therefore, the integration of organic and inorganic fertilizers are recommended to be applied by farmers in the tropics.

The aim of experiment is to determine the effect of application of organic-liquid fertilizer and inorganic fertilizer recommendation (Urea, ABSTRAKPercobaan ini bertujuan untuk mengetahui pengaruh aplikasi pupuk organik cair dan rekomendasi pemupukan anorganik (Urea, SP-36 dan KCl) terhadap pertumbuhan, produksi, dan kualitas pasca panen jagung manis (Zea mays var. saccharata Sturt.) varietas Talenta. Penelitian dilakukan di Kota Sepang Jaya, Labuhan Ratu, Bandar Lampung, Provinsi Lampung pada bulan Desember 2015 sampai Maret 2016. Percobaan menggunakan Rancangan Acak Kelompok (RAK) 1 faktor dengan 6 taraf perlakuan dan tiga ulangan. Susunan perlakuan adalah (L1) kontrol (tanpa pupuk); (L2) pupuk anorganik 100% rekomendasi; (L3) pupuk organik cair; (L4) pupuk organik cair + pupuk anorganik 100% rekomendasi; (L5) pupuk organik cair + pupuk anorganik 60% rekomendasi; dan (L6) pupuk organik cair + pupuk anorganik 20% rekomendasi. Penggunaan pupuk organik cair, rekomendasi pemupukan anorganik, atau kombinasi keduanya menghasilkan pertumbuhan yang lebih tinggi, hasil, dan kualitas pascapanen yang lebih baik daripada perlakuan tanpa pupuk. Kombinasi pupuk organik cair dan pupuk anorganik (Urea, SP-36 dan KCl) 20% rekomendasi dapat menjadi pupuk ekonomis alternatif untuk menghasilkan jagung manis yang optimum dan juga perlakuan tersebut menunjukkan penyusutan bobot tongkol yang terendah jika dibandingkan dengan perlakuan lain.

AbstrakPertanian organik semakin populer di kalangan petani sebagai praktik pertanian alternatif. Kebutuhan unsur hara mayor dalam pertanian organik dapat dicukupi dari bahan alamiah yaitu dari bahan ekstrak tanaman. Organ tanaman kaya akan unsur hara misalnya ekstrak tanaman daun tanaman lamtoro kaya akan unsur Nitrogen, ekstrak batang pisang kaya akan unsur Fosfor, dan ekstrak sabut kelapa kaya unsur Kalium. Tujuan dari kegiatan pengabdian ini adalah: 1. Meningkatkan pengetahuan para petani tentang pupuk organik cair 2. Meningkatkan keterampilan petani untuk membuat pupuk organik cair dari bahan ekstrak tanaman. Kegiatan pengabdian pada masyarakat ini telah dilaksanakan pada bulan November 2017. Kegiatan pengabdian pada masyarakat ini bertempat di Kelurahan Marga Agung, Kecamatan Jatiagung, Lampung Selatan. Materi yang disampaikan pada kegiatan pengabdian pada masyarakat ini adalah materi pertanian organik yaitu teknik pembuatan pupuk organik cair dari ekstrak tanaman. Pada akhir pengabdian diperoleh bahwa (1) pengetahuan petani sasaran tentang manfaat pemupukan melalui pupuk organik cair telah meningkat 62%. (2) Tanggapan petani terhadap kegiatan demonstrasi cara pembuatan pupuk organik cair cukup baik dan positif serta petani ingin mencoba membuat sendiri pupuk organik cair untuk dicobakan pada lahan budidaya tanaman pangan petani.Kata Kunci: pertanian organik, penyuluhan, pupuk organik cair, lamtor, batang pisang, sabut kelapaAbstractOrganic farming is increasingly popular among farmers as an alternative agricultural practice. The need of major nutrients in organic farming can be provided from natural ingredients that are from plant extract material. Plant organs rich in nutrients such as leaf plant extracts lamtoro rich in Nitrogen, banana stem extract rich in phosphorus and fitohormone and extract coconut fiber rich in potassium. The purpose of this extension activity is 1. Improving knowledge the farmers about liquid organic fertilizer 2. Increase skills farmers to make liquid organic fertilizer from plant extract material. This community service activity was held in November 2017. The community service activity is located in Kelurahan Marga Agung, Jatiagung sub-district, South Lampung. Material presented on extension activities in the community that is an organic farming material namely production technique of a liquid organic fertilizer from plant extracts. At the end of the extension, it was found that (1) knowledge of target farmers about the benefits of fertilization through liquid organic fertilizer has increased 62 %. (2) The farmers' perception of the demonstration method activity of liquid organic fertilizer is quite good and positive and the farmers want to try to make their own liquid organic fertilizer to be tested on food-crops farming of farmersKey words: organic farming, extension, liquid organic fertilizer, lantoro, banana stem, coconut fiber

Tujuan dari penelitian ini adalah untuk mengetahui apakah pupuk cair urine sapi dapat mengurangi penggunaan Urea dalam upaya untuk meningkatkan pertumbuhan dan produksi jagung manis. Penelitian ini dilakukan di Bandar Lampung. Mulai April sampai Juli 2015. Penelitin  menggunakan rancangan acak kelompok dengan lima perlakuan, yaitu (P0) kontrol, (P1) pupuk Urea 270 gram, (P2) urine sapi 7 ml/l (7.000 ppm) pada 2, 4, 6, dan 8 MST, (P3) pupuk Urea 135 gram dan urine sapi 7 ml/l (7.000 ppm) pada 3 dan 5 MST dan (P4) pupuk Urea 135 gram dan urine sapi 7 ml/l (7.000 ppm) pada 2, 4, 6, dan 8 MST.  Hasil penelitian menunjukkan bahwa pupuk cair urine sapi  memberikan pengaruh nyata terhadap variabel pertumbuhan dan produksi tanaman jagung manis.  Perlakuan P2 pada 2, 4, 6 dan 8 MST direkomendasikan sebagai pupuk alternatif Urea.
