Abstract

Arbuscular Mycorrhiza Fungi (AMF) is a form of  mutualistic symbiosis between fungi and plant roots. FMA existence in  soil is influenced by several agricultural activities such as tilling and fertilizing. The purpose of this study (1) Obtaining  data on the number of FMA in each treatment and conservation tillage . (2) Knowing  the types FMA in each treatment and conservation tillage planting season  to 29. The study was a randomized block design (RAK) , arranged as factorial (2x3), with three replications. The first factor is the intensive tillage (T1), no-tillage (Zero Tillage) (T2) Minimum tillage (Minimum Tillage), and  Land Intensive (Full Tillage) (T3); and the second factor is without fertilizer N (N0) and fertilizer application of 100 kg N ha-1 (N1), and  Fertilizer of 200 kg N ha-1 (N2). The method used in this study is a description method by observation techniques, the method used for the isolation of spores of strain engineering castings and followed by centrifugation. Observations were made using a microscope binoculars and digital camera, the spores are observed then grouped based on their morphological characters, identification of mycorrhizal done using a guide book "Working with mycorrhizas in Forestry and Agriculture" and reaffirmed by using INVAM website.  Based on results  of research and discussion can be concluded. The number of spores in the soil no tillage without nitrogen doses is 1,333 at doses 100 kg N spore number is 1,253, and as high as 1,648 spores at dose of 200 kg N. The number of spores on minimum tillage  200 kg of nitrogen dose was 271, on 100 kg dose was 520 spores, and without nitrogen fertilizer contained spores 780. at most that  intensive tillage highest number of spores on spore number without nitrogen fertilizer is 4.078, and the number of spores 1,124 at the dose of 100 kg nitrogen, 941 the number of spores nitrogen dose of 200 kg. There are four genera of spores discovered in minimum tillage with various doses Nitrogen fertilizer is the genus Glomus, Acaulospora, Gigaspora, and Scutelospora. Genus most obtained is Glomus and Acaulospora. Type spores were found from 4 genera dominated by genus Glomus with a variety of different types.

Abstract

Tujuan dilaksanakannya kegiatan PKM di Desa Wiyono ini adalah agar petani mampu melaksanakan perbanyakan Trichoderma sebagai agen pengendali hayati dengan media beras. Selain itu, diharapkan petani mampu mengurangi penggunaan pupuk dan pestisida kimia yang dapat mencemari lingkungan dan menambah biaya produksi petani. Guna mendukung pelatihan perbanyakan Trichoderma sp sebagai agen pengendali hayati pada Kelompok Wanita Tani Mentari, tim pengusul telah merancang metode yang digunakan untuk mencapai tujuan dan target khusus kegiatan ini berbentuk penyuluhan, demonstrasi, pelatihan, konsultasi, dan bimbingan. Kegiatan PKM ini berjalan dengan baik karena anggota Kelompok Wanita Tani Mentari yang sangat antusias mengikuti demonstrasi dan pembimbingan. Para peserta juga melaksanakan secara langsung perbanyakan Trichoderma pada media beras, sehingga diharapkan kegiatan ini akan terus berlanjut supaya mengurangi penggunaan pupuk dan pestisida kimia. Hasil perbanyakan dapat dilihat tiga minggu kemudian. Hasil perbanyakan Trichoderma yang diperoleh dapat langsung digunakan sebagai pupuk maupun pestisida pengendali patogen penyebab penyakit pada tanaman. Berdasarkan kegiatan PKM yang telah dilakukan dapat disimpulkan bahwa kemampuan pengetahuan peserta meningkat sebesar 62%.

Abstract

One of the obstacles that resulted in a decrease in palm oil production was the presence of weeds. Weed control needs to be done to suppress weed growth. A mixture of methyl metsulfuron herbicide and acetic acid herbicide can be used to control weeds. This research was conducted in Politeknik Negeri Lampung’s Teaching Farm. This study used a factorial randomized block design with two factors, and each treatment combination was repeated three times. The first factor is the methyl metsulfuron herbicide 20% with 3 level doses: 0 g.ha-1, 45 g,ha-1, and 75 g.ha-1 and the second factor is acetic acid herbicide 20% with 3 level doses: 0 ml.ha-1, 225 l.ha-1, and 315 l.ha-1. The result showed that the combination of methyl metsulfuron herbicide 75 g.ha-1 and acetic acid herbicide 315 l.ha-1 effective reduce weed dry weight up to 5.50 grams at 5 WAA and reduce weed cover percentage to 8% at 6 WAA. The dominant weeds that arises after the application of the methyl metsulfuron herbicide and acetic acid is Asystasia gangetica, Paspalum conjugatum, Panicum dichotomiflorum, Stachytarpeta indica, and Imperata cylindrica.

Abstract

Cocoa pod sucking (Helopeltis spp.) is one of the pests that causes a productivity decrease of cocoa pod in Indonesia. In terms of control, many farmers in Indonesia are still using synthetic insecticides that are not environmentally friendly, so intoxicating yam (Dioscorea hispida Dennts) and tropical whiteweed (Ageratum conyzoides L.) are used as botanical insecticide that are environmentally friendly. The objective of this research is to determine the effect of botanical insecticide that made of intoxicating yam extract, tropical whiteweed extract, and mixed extract of intoxicating yam and tropical whiteweed on the mortality of cocoa pod sucking pests. This research was carried out from November 2020 to February 2021, at the Plant Laboratory II Estate Crop Department, Politeknik Negeri Lampung. The research used a Randomized Block Design (RBD) consisting of four treatments, namely: P0 (control), P1 (intoxicating yam extract), P2 (tropical whiteweed extract), and P3 (combination of both extracts), which were repeated six times. The highest mortality of cocoa pod sucking pests was found in treatment P1 (72.73%). The mortality of cocoa pod sucking pest was caused by extract of intoxicating yam which contains the active ingredients of saponins, alkaloids, flavonoids, and cyanide which enter the digestive system of the cocoa pod sucking pest as stomach poisons, resulting in the death of the cocoa pod sucking pest. Based on the results of the research, it was concluded that intoxicating yam extract is the most potential as botanical insectiside for cocoa pod sucking pest.

Abstract

Desa Wiyono merupakan salah satu desa yang ada di Kecamatan Gedong Tataan, Kabupaten Pesawaran Provinsi Lampung. Mata pencaharian sebagian besar penduduknya adalah petani kakao. Luas areal perkebunan kakao rakyat di Kecamatan Gedong Tataan pada tahun 2022 adalah 1.299 hektar dengan produksi 1.560 ton (BPS Kabupaten Pesawaran, 2022). Saat ini kulit kakao merupakan limbah pertanian yang melimpah di Desa Wiyono. Limbah kulit kakao tersebut akhirnya menjadi masalah di kebun petani, karena penumpukan limbah kulit kakao dapat menjadi tempat yang ideal bagi berkembangnya inang penyakit dan hama tanaman kakao. Hal tersebut karena para petani hanya berfokus pada pemanfaatan buah kakaonya saja. Padahal limbah kulit kakao memiliki kandungan yang cukup baik jika diolah menjadi pupuk organik. Pupuk organik merupakan bahan pembenah tanah yang paling baik dan alami dari pada bahan pembenah buatan/sintesis. Pada umumnya pupuk organik mengandung hara makro N, P, K rendah tetapi mengandung hara mikro dalam jumlah cukup yang sangat diperlukan pertumbuhan tanaman. Salah satu pupuk organik yang mudah diaplikasikan adalah pupuk organik cair (POC). Pupuk organik cair adalah larutan dari hasil pembusukan bahan-bahan organik yang berasal dari sisa tanaman, kotoran hewan, dan manusia yang kandungan unsur haranya lebih dari satu unsur. Kelebihan dari pupuk organik ini dapat secara cepat mengatasi defisiensi hara, tidak bermasalah dalam hal pencucian hara, dan mampu menyediakan hara secara cepat. Oleh karena itu, para petani perlu mendapatkan transfer teknologi pembuatan POC karena anggota kelompok wanita tani belum pernah melakukan pembuatan POC sebagai upaya mengurangi limbah kulit kakao yang melimpah. Tim telah merancang metode yang diterapkan dengan cara penyuluhan, demonstrasi, pelatihan, konsultasi dan bimbingan, serta evaluasi. Saat dilakukan transfer pembuatan POC, seluruh peserta kegiatan antusias untuk mengetahui cara pembuatan POC.
