Abstract

Article Highlights- Botanical inventory in Halmahera island, North Maluku has found the species Melothria pendula for the first time.- In Indonesia, the species Melothria pendula is previously known only from Java, Sumatra, Sulawesi, and Lesser Sunda Island.- DNA barcodes for the species Melothria pendula from Indonesia firstly deposited in NCBI GenBank. AbstractThis study was conducted to explore Melothria pendula on Halmahera Island. Previously, the species is known to occur in Bali, Sulawesi, Sumatra, Java (Indonesia), Malay Peninsula, Sabah (Malaysia), as well as the Philippines. Results of this study improved insights into the current knowledge about geographic distribution of Melothria. Moreover, the description of the species, habitat, critical taxonomic notes, color plates, distribution map, and DNA barcode were also presented in this study.

Abstract

Ornamental plants have now developed as souvenirs given at a wedding. Requirements for souvenirs, the plants should be tiny, lush, and have much of flowers. So its growth needs to be modified using a growth regulator paclobutrazol. This study aimed to determine the response of angelonia plants to the application of paclobutrazol at several levels of concentration and determine the concentration of paclobutrazol which has the best appearance of angelonia plants. This research method used a randomized block design (RBD) with treatment of 6 levels of paclobutrazol concentration, namely 0 ppm, 30 ppm, 60 ppm, 90 ppm, 120 ppm and 150 ppm with 3 replications. The F test and further tests were carried out an Orthogonal Polynomials. All tests were carried out at the 5% level. The results showed that the application of paclobutrazol at a concentration level of 30-150 ppm, was effective in suppressing the growth rate of angelonia plants in the vegetative phase. This value was proved by the results of the questionnaire that, the highest visual value was obtained at a concentration of 150 ppm. But with the increasing concentration of paclobutrazol, the freshness of  flowers became shorter. Keywords: Angelonia, Concentration, Paclobutrazol

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

Abstract

Tujuan kegiatan ini adalah untuk mengenalkan komoditas baru yaitu bunga krisan potong kepada kelompok tani dan kelompok wanita tani di Desa Sungai Langka, Kec. Gedong Tataan, Pesawaran, Lampung yang mengelola agrowisata. Bunga krisan potong ini diharapkan menjadi komoditas baru agrowisata yang dapat diandalkan, mengingat agrowisata di Sungai Langka mengandalkan komoditas tahunan seperti durian, jeruk, dan kopi. Metode kegiatan pengabdian ini adalah pembuatan demplot budidaya bunga krisan potong dalam rumah pelindung yang terbuat dari bambu dan atap plastik UV. Selain itu dilakukan juga ceramah dan diskusi tentang budidaya bunga krisan potong. Hasil akhir dari kegiatan ini adalah petani mulai mengenal teknik budidaya krisan potong. Hasil penting lainnya adalah seluruh peserta setuju (100%) perlu adanya komoditas baru untuk dikembangkan dan setuju  (100%) bunga krisan potong dikembangkan di Desa Sungai Langka sebagai komoditas pendukung agrowisata.

Tujuan Kegiatan ini adalah untuk mengenalkan komoditas baru yaitu bunga krisan potong kepada kelompok tani dan kelompok  wanita tani di Desa Sungai  Langka, Kec. Gedong Tatan, Kab. Pesawaran Lampung. Bunga krisan potong diharapkan dapat menjadi komoditas baru yang dapat diandalakan mengingat selama ini agrowisata di Sungai Langka mengandalkan komoditas tanaman tahunan seperti jeruk dan kopi. Metode kegiatan pengabdian ini adalah pembuatan demplot budidaya krisan potong di dalam rumah pelindung berukuran 5 m x 8 m yang terbuat dari rangka bambu dan atap plastik UV. Hasil akhir kegiatan ini adalah petani mulai mengenal budidaya krisan potong. Hasil penting lainnya adalah 100% anggota kelompok setuju bunga krisan dikembangkan sebagai komoditas baru di Desa Sungai Langka.

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.

Abstract

In the revision of the cucurbitaceous genus Trichosanthes in Malesia by Rugayah & W.J.J.O. de Wilde (Reinwardtia 11(4): 262. 1999), the type of the proposed new species T. kinabaluensis Rugayah was erroneously indicated as consisting of two collections, viz. Chew, Corner & Stainton 2830 and De Wilde & Duyfjes SAN 139472. This latter appeared to be contrary to art. 37.3 of the International Code of Botanical Nomenclature (Tokyo Code, 1994), rendering the new species invalid. This species is validated below by indicating a single type. I am grateful to Dr. Dan H. Nicolson (US Washington), who kindly made me aware of the mistake.
