Abstract:
Rhizobacteria was group of bacteria that colonize roots, affect growth and control plant pathogensBased on the results of previous studies, 6 isolates have the best ability to control G. boninense in oil palm seedlings. To determine the ability of these isolates, characterization needs to be done. This study aims to identify the molecular isolates of selected rhizobacteria indigenous that act as biocontrol agents G. boninense. Molecular identification of selected rhizobacteria isolates using the 16S rRNA gene. The results showed that All RBI isolates were identified as different species of Bacillus paramycoides strain MCCC (RZ1A 2.1), Microbacterium paraoxydans strain CF36 (RZ2B 1.1), Bacillus albus strain MCCC 1A02146 (RZ2C 2.1), Bacillus cereus strain JCM 2152 (RZ2E 2.1), Serratia marcescens strain NBRC 102204 (RZ2E 1.2), Bacillus cereus ATCC 14579 (RZ1E 2.1).

Abstract:
Industri rokok tidak kalah penting pengaruhnya terhadap perekonomian Indonesia yaitu, telah memberikan kontribusi yang cukup besar baik dari tenaga kerja maupun pendapatan negara melalui cukai. Adanya FCTC (Framework Convention on Tobacco Control) menyebabkan industri rokok mengalami tekanan publik yang sangat kuat, terutama dikaitkan dengan pencanangan agenda global Hari Kesehatan Sedunia. Ini berdampak terhadap petani tembakau sebagai pemasok bahan baku olahan rokok, banyak petani tembakau yang pada akhirnya mengganti tanamannya dengan tanaman lain yang memiliki nilai kurang ekonomis dibandingkan tanaman tembakau. Untuk mengantisipasi dampak FCTC tersebut, perlu ada inovasi teknologi dalam aneka produk olahan tembakau non rokok. Beberapa aneka produk olahan tembakau non rokok, adalah: pupuk, pestisida, farmasi, cat untuk batik, briket, minyak tembakau,dan lain-lain yang memiliki nilai tambah  lebih tinggi dibandingkan dalam bentuk rokok. Metode penelitian yang digunakan adalah survey dengan pendekatan kuantitaif deskriptif . Responden (petani tembakau) diambil di lima Kecamatan  pada Kabupaten Bandung, yang memiliki potensi besar untuk komoditas tembakau, dan merupakan salah satu sentra produksi tembakau setelah kabupaten Garut  di Jawa Barat. Kelima wilayah penelitian  ini merupakan wilayah binaan dari Disperindag Kabupaten Bandung dalam mengembangkan produk olahan tembakau non rokok.  Wawancara juga dilakukan terhadap Informan, yaitu: ketua dan pengurus Kelompok Tani Tembakau, Asosiasi Tembakau Indonesia, staf instansi terkait (Disperidag), dan tokoh masyarakat di wilayah penelitian. Teknik FGD juga dilakukan. Data hasil penelitian ditabulasikan, dideskripsikan dan dianalisis melalui pendekatan system thinking. Hasil penelitian menunjukan, masih banyak kendala dalam mengembangkan agroindustri produk tembakau non rokok, dan model pengembangannya harus dibangun secara terintegrasi dan  menyeluruh, karena terkait dengan berbagai stakeholder.

Abstract:
Iklim merupakan salah satu faktor yang mempengaruhi pertumbuhan dan produksi kelapa sawit, salah satu unsur iklim yang sangat penting adalah hujan. Hujan sebagai sumber air utama dalam memenuhi kebutuhan tanaman kelapa sawit. Penelitian ini bertujuan untuk memetakan tipe iklim wilayah Bintang Bayu serta mengetahui tren curah hujan dalam kurun waktu 10 tahun (2010-2019) di Kecamatan Bintang Bayu, Kabupaten Serdang Bedagai Provinsi Sumatera Utara. Penelitian dilaksanakan menggunakan metode Sistem Informasi Geografis (SIG) dan deskriptif analitis. Data curah hujan bersumber dari citra satelit (Data Chips-2.0, UCSB) yang diperoleh dari Badan Meteorologi dan Geofisika (BMKG) Wilayah I Medan yang digunakan sebagai dasar untuk menentukan bulan kering dan bulan basah berdasarkan Schmidt-Ferguson, selanjutnya ditentukan nilai Q dan untuk memetakan iklim digunakan Software ArcGIS 10.3. Evaluasi kesesuaian curah hujan dilakukan dengan cara membandingkan data pengamatan curah hujan tahunan dengan Kriteria Kesesuaian Lahan Kelapa Sawit berdasarkan Balai Besar Penelitian Dan Pengembangan Sumber Daya Lahan Pertanian. Tren curah hujan bulanan dalam kurun waktu 10 tahun dianalisis menggunakan regresi linier. Hasil penelitian menunjukkan bahwa Kecamatan Bintang Bayu memiliki tipe iklim A (hutan hujan tropis), yang mana pada wilayah dengan tipe iklim A cocok untuk tanaman kelapa sawit. Berdasarkan sebaran hujan tahunan, terdapat dua sebaran hujan yaitu 2.500-3.000 mm tahun-1 dan 3.000-3.500 mm tahun-1 dan tidak ditemukan wilayah dengan sebaran hujan tahunan 2.000-2.500 mm tahun-1, dengan demikian wilayah Bintang Bayu termasuk kelas S2. Dalam kurun waktu sepuluh tahun, terjadi penurunan curah hujan pada bulan Januari, Mei, Juli dan Oktober sedangkan pada bulan-bulan lainnya terjadi kenaikan curah hujan

Abstract:
The policy objective of Government Purchase Price (HPP) of plantation white sugar in Indonesia is to increase the production. However, while the government increase the HPP, the production was decreased. The purpose of this study was to analize the impact of HPP policy on production of plantation white sugar in Indonesia. This study uses ex-post simulation based on econometrics model (build from monthly time series data from 2012 until 2017, consist of 13 equations and estimated using 2SLS method). The results, ex-post simulation shows that an increase HPP causes an increase in plantation white sugar production and producer surplus. However, an increase in labor wages cause decreased in production. The increase HPP also causes an increase in producer surplus. Based on producer surplus, the biggest impact of the increase in HPP was felt by the farmers.

Abstract:
Patchouli (Pogostemon cablin Benth) is a plant that produces essential oils and important foreign exchange earner for Indonesia. Using superior clones with the right fertilizer application will increase the yield of patchouli oil. The research aims to obtain patchouli plants that have the best response of urea fertilization application and optimum dosage of urea for patchouli plant growth. The study was conducted at the Politeknik Negeri lampung’s teaching farm in December 2018 until May 2019. The experiment was conducted using a factorial randomized block design (RBD), consisting of two treatment factors, namely the type of urea clone. The first factor is the type of clone consisting of 2 levels, namely NPL 9 clone and Lhokseumawe clone. The second factor is the treatment of urea doses consisting of 4 levels, namely control, 250 kg.ha-1, 300 kg.ha-1, and 350 kg.ha-1. Variables observed included plant’s height, bough, diameter, number of leaves, stalk angle, chlorophyll content, wet weight of plant, wind dry weight of plant, and yield. The results of research showed NPL 9 clone had a superior appearance and 350 kg.ha-1 of urea dose was the optimal dose compared to other doses and could increase patchouli yield 2,3% compared to the control treatment.

Abstract:
Root trainer technology can be an alternative for rubber plant nursery that have ease in transportation and distribution. Organic materials which are lightweight, porous, and contain nutrients are considered suitable for root trainer growing media. This research was carried out at Sungei Putih Research Center Greenhouse, Deli Serdang from January - May 2019. The research was arranged based on a Randomized Block Design (RBD) with 4 media combination treatments namely: top soil (P0), empty bunches and manure (P1), empty bunches and rice husks (P2), and empty bunches and solid decanters (P3). The results showed that the planting media did not have a significant effect on plant growth including stem diameter, plant height, and number of leaves, as well as the percentage of successful grafting. The treatment of oil palm empty fruit bunches and solid decanter gave better growth than other organic materials. The availability of empty bunches and solid decanter in North Sumatra is relatively abundant so that it can support rubber nurseries throughout the year.
