<p>The increasing demand of jamu/traditional medicine was followed by the demands of raw materials quality based on Good Agricultural and Collection Practices (GACP) yield and standard quality. Bio-insecticide is an effort to fulfill the standard based on GACP. Indonesian’s biodiversity have many potential raw materials of bio-insecticides, such as <em>Tithonia diversifolia</em>. The most common pest in the medicinal plants is <em>Aleurodicus dugesii</em> (giant whiteflies), this insect belong to Hemiptera ordo and Aleyrodidae family. The research was conducted to determine the antifeedant and anti-oviposition activity of Tithonia bio-insecticide against giant whitefly on Coleus species. The experimental design was completely randomized design (CRD) with five treatments of Tithonia leaves extract consentrations. Those consentrations were 0, 4, 2, 1, and 0,5 mg L^-1. The treatments were tested by using a no-choice test with three replications. The extract of Tithonia leaves was prepared by infundation method by using water solvent. Results showed that extracts of Tithonia with the smallest concentration (0,5 mg L^-1) has an active role as an anti-oviposition and antifeedant on giant whiteflies.</p>

<p>Centella (<em>Centella asiatica</em> L. Urban) originally is a wild plant that is being cultivated to be medicinal and cosmetics raw material. The process of centella cultivation is relatively easy and can be grown in a variety of altitudes. One obstacle in centella cultivation is weed growth. The proper handling of weeds in centella plantation requires data on the weed types and characteristics. This research aimed to determine the weed types and the amount of weed found in centella cultivation. Sampling was carried out purposively based on the presence of weeds in the cultivation area. Weed inventory was carried out using linear vegetation methods in 12 plantation beds of centella, with a size of 6 x 2 m² each. Observations were made during weeding on one cropping season. Weed inventory was carried out by recording the number of species and number of individual weed and taking documentation of weeds that were recorded for identification purposes. Research data were analyzed by using vegetation analysis. The weed vegetation analysis on centella plantations showed that there were 35 species of weeds identified from 20 plant families. <em>Cyperus rotundus</em> L. dominates the weed vegetation in centella plantations because of its high adaptability and its allelochemical exudates. To sustainably cultivate the centella, proper techniques of weed controls need to be applied by considering the nature of <em>Cyperus rotundus</em> L.</p>

Dunia berkembang kian cepat seiring majunya teknologi informasi. Komunikasi kini menjadi tidak terbatas. Dengan banyaknya kemudahan untuk melakukan pengaksesan informasi, adakalanya diperlukan pengamanan informasi tersebut. Pengamanan ini berfungsi menangani pencegahan atas sampainya informasi ke tangan yang tidak berhak yang dapat menimbulkan kerugian bagi pemilik informasi. Metode Playfair Cipher merupakan salah satu metode yang digolongkan dalam kriptografi klasik yang proses enkripsinya menggunakan pemrosesan dalam bentuk blok-blok yang sangat besar. Metode Playfair Cipher menggunakan pembentukan tabel berdasarkan kunci yang diketahui. Penulis melakukan modifikasi metode Playfair Cipher menggunakan tabel 8x8 ini mempersulit pemecahan analisis digram dan frekuensi analisis karena semakin acak isi tabel akan menghasilkan ciphertext yang acak. Hasil pengujian ini yaitu pada aplikasi ini memberi dua layanan keamanan data saja yaitu Confidentiality dan Authentication, penggunaan kunci Metode Playfair Cipher jika penggunaan kunci yang digunakan panjangnya lebih pendek maka semakin cepat juga waktu enkripsi dan dekripsinya dan terdapat karakter tambahan yaitu karakter Space

Latar Belakang: Diabetes melitus (DM) adalah penyakit metabolik yang umumnya ditandai dengan peningkatan kadar glukosa darah yang membutuhkan pemantauan dan kontrol yang tepat. Neuropati perifer (kerusakan saraf) adalah salah satu komplikasi paling serius dari diabetes. Jika dibiarkan maka dapat menyebabkan ulkus diabetik. Salah satu upaya yang dapat dilakukan untuk mencegah terjadinya komplikasi neuropati diabetik adalah perawatan kaki. Efikasi diri menjadi sesuatu yang penting dalam melakukan manajemen DM yang bertujuan agar penderita DM melakukan perawatan diri sesuai dengan yang dianjurkan.Tujuan: Penelitian ini bertujuan untuk mengetahui hubungan antara efikasi diri dengan perawatan mandiri kaki pada pasien diabetes melitus di Poli Penyakit Dalam RSUD Sultan Syarif Mohamad Alkadrie Pontianak.Metode: Jenis penelitian kuantitatif dengan desain observasional analitik melalui rancangan cross sectional study. Teknik sampling yang digunakan adalah accidental sampling dengan jumlah 94 responden. Instrumen yang digunakan adalah kuesioner Foot Care Confidence Scale (FCSS) dan kuesioner Standart Kuesioner Nottingham Assesment of Functional Foot Care (NAFF). Uji statistik yang digunakan adalah Chi Square. Hasil: Hasil uji statistik menunjukkan bahwa p value 0.000 (<0.05).Kesimpulan: Terdapat hubungan antara efikasi diri dengan perawatan mandiri kaki pada pasien diabetes melitus di Poli Penyakit Dalam RSUD Sultan Syarif Mohamad Alkadrie Pontianak.

Echinaceae is introduced medicinal plant as immunomodulator. The high demand of echinaceae as raw material for immunomodulatory herbal medicine by the industries, requires the increase in quantity and quality of cultivated echinaceae. Thus, the use of fertilizer is necessary. However, to ensure the safety of raw materials for herbal medicine industry, the use of organic fertilizer becomes one of the important components. Organic fertilizer used can be in the form of solid fertilizer such as dung manure, compost and green manure. Various plants can be utilized as a source of green manure such as Tithonia diversifolia, because of its high N content. The aim of this research was to evaluate the effect of the dosage of dung manure and green manure from <em>T. diversifolia</em> on echinaceae biomass and echinacoside contents. The research was arranged in Factorial Randomized Block Design with two treatments, three dosages of dung manure (P) 0; 2.5; 5 ton.ha^-1, and three dosages of green manure from <em>T. diversifolia</em> (T) 0; 10 and 20 ton.ha^-1. The treatment combinations were repeated three  times. The results  showed  that there was no interaction between <em>T. diversifolia </em>green manure and dung manure usage. The use of  <em>T. diversifolia</em>  fertilizer alone was not evidently increased  the fresh weight of biomass at 20 ton.ha^-1. The use of  <em>T. diversifolia</em> and dung manure showed no significant effect on echinacoside content.

ABSTRACT Aleurocanthus camelliae was identified as a new species in 2011. The distribution of this species in worldwide is not widely known, including in Indonesia. These findings report the existence of A. camelliae in Indonesia as a new record based on morphological characters, previously identified as A. spiniferus. The study was carried out in August 2019 using an observation method in three locations with different altitudes around Mount Lawu. The result showed the species parasitized 13 medicinal plant species in two observation location (495 m asl and 1,200 m asl). Keywords: Aleurocanthus spiniferus, morphology, camellia spiny whitefly, invasive pest, medicinal plant. ABSTRAK Aleurocanthus camelliae diidentifikasi sebagai spesies baru telah dilakukan pada tahun 2011. Sebarannya diseluruh dunia belum banyak diketahui, termasuk di Indonesia. Laporan ini menyampaikan hasil pengamatan tentang keberadaan A. camelliae di Indonesia sebagai catatan baru berdasarkan karakter morfologi. Penelitiandilakukan pada bulan Agustus 2019 dengan metode observasi di tiga lokasi dengan ketinggian berbeda di sekitar Gunung Lawu. Hasil penelitian menunjukkan bahwa spesies ini telah memarasit 13 jenis tumbuhan obat di dua lokasi pengamatan pada ketinggian 495 m dpl dan 1.200 m dpl.
