Abstract

Spatifilum is classified as a shade plant that can survive in environments with minimal sunlight or shading Spatifilum plants are known to absorb toxins or clean indoor air from pollutants such as benzene and formaldehyde. Efforts to stimulate flowering and the emergence of spatifilum seedlings include using a growth regulator in the form of benzyladenine (BA). The aim of this research was to determine the difference in the effect of residual BA with and without BA on the flowering of spatifilum plants in the second period. Data collection was carried out in August – November 2022 at the Horticulture Greenhouse, Faculty of Agriculture, University of Lampung. This research used a Complete Randomized Block Design (RAKL) with a single treatment. The treatment consisted of 5 BA concentration treatments, namely 0 ppm, 20 ppm two applications, 20 ppm four applications, 40 ppm two applications, and 40 ppm four applications with four repetitions. The data from this research were analyzed using the barlet test and the additivity test was carried out using the Tukey test. Then the data was analyzed using variance (Anara) and orthogonal contrast tests. The results of the research showed that there were significant differences in the variables of increasing the number of seedlings and increasing the number of flowers. BA concentration of 20 ppm was significantly able to increase the number of offspring compared to a concentration of 40 ppm, meanwhile, a concentration of 40 ppm with a frequency of giving 2x significantly increased the number of flowers compared to a frequency of giving 4x

Reinwardtia 15(2): 111 –114. — A living collection of Bogor Botanic Gardens, planted in plot XXIV.A.192-192a and originated from Kemiri Said Nature Reserve, Cyclops Mountain in Papua collected by Lugrayasa (LG 1352), is described and illustrated as a new species, namely Murraya cyclopensis Astuti & Rugayah. The species is closely related to Murraya paniculata (L.) Jack, in vegetative and flower structures, but differ in the presence of indumentum on twig, rachis and petiole, smaller size of flowers, red globose fruits, and orbicular seeds covered by densely short hairs and red aril.

Abstract

Pekon Giham Sukamaju termasuk dalam wilayah dataran tinggi di Kecamatan Sekincau Lampung Barat yang cocok untuk usaha pertanian, khususnya tanaman hortikultura. Beberapa petani di Pekon Giham, Sukamaju mulai tertarik  menanam  jeruk  sebagai  komoditas  unggulan baru, tetapi pemahaman dalam budidaya jeruk masih minim dan belum sesuai dengan kaidah GAP (good agricultural practices) untuk dapat menghasilkan panenan yang sehat, bermutu tinggi, dan berdaya saing sehingga mampu meningkatkan  pendapatan  petani.  Pengamatan di lapang menunjukkan  bahwa petani menanam jeruk seadanya terutama dalam pemeliharaan tanaman jeruk meliputi pemupukan dan pemangkasan. Tujuan kegiatan ini adalah (1) memberikan pengetahuan teoritis tentang teknik budidaya jeruk di dataran tinggi menurut kaidah GAP, (2) agar petani mengetahui dan mampu menerapkan teknologi bujangseta pada pertanaman jeruk. Hasil kegiatan menunjukkan bahwa terjadi peningkatan pengetahuan pemeliharaan jeruk dengan penerapan teknologi bujangseta sebesar 43,3%, terutama dalam hal pemangkasan dan pemupukan. Pemahaman dalam praktik penerapan teknologi bujangseta hanya terlihat pada lima orang peserta dari 13 anggota petani jeruk. Ketrampilan teknis budidaya jeruk yang dikuasai terutama pemupukan dan sebagian pemangkasan. Manajemen pengendalian OPT kurang dipaham petani.
