Sweet leaf (Sauropus androgynus (L.) Merr.), a leaf vegetable that is generally propagated vegetatively with cuttings. This study aims to determine the effect of accession and administration of natural and synthetic auxin growth regulators on the growth of sweet leaf cuttings. This study uses factorial Randomized Complete Design consisting of two factors, namely accession (Banten from Pandeglang, Bogor from Tajur, and Cianjur from Cugenang) and auksin combination (IBA 100%R, urine 25%R + IBA 75%R, urine 50%R + IBA 50%R, urine 75%R + IBA 25%R, and urine 100%R). The results showed that the growth of Cianjur accession had the best results on the percentage of growth cuttings, the percentage of shoot buds, shoot height, number of shoots, number of leaves, percentage of rooted cuttings, and number of roots compared to Banten and Bogor accessions. Giving urine 100%R significantly increases plant height, shoot height, number of shoots, and number of sweet leaf plant roots compared with other auxin combinations. The combination treatment of auxin and accession showed results that were not significantly different from the variable root length and weight of the harvest. In sweet leaf plants, cow urine can replace the use of IBA (Indole Butyric Acid). Keywords: Sauropus androgynus, vegetative, urine, IBA

Abstract Tissue culture techniques can increase the number of garlic seedlings. The purpose of this research is to determine the effect of NAA and coconut water in increasing the number of garlic seeds. This research used a Completely Randomized Design of two factors. The treatment used is NAA with concentrations of 0 ppm, 0.5 ppm, 1 ppm, 1.5 ppm, and coconut water concentrations of 0%, 10%, 20%. The variables observed were shoot emergence time, root emergence time, number of shoots, number of roots, number of leaves, shoot height, root length, and number of plantlets. The results showed that the addition of coconut water 20% without the addition of NAA in 1 bulb can produce 3.33 planlets and the results of explant propagation in 1 bulb can produce the number of shoots as many as 15.33 shoots. Giving coconut water with concentrations of 10% and 20% can increase the number of leaves, shoot height, and some planlets. The concentration of NAA 0.5 ppm can accelerate the root emergence time on garlic explant.

Tribulus (Tribulus terrestrisL.) is a medicinal plant with considerable implementation such as aphrodisiac and anti‑inflammation drugs. This research was conducted to study the effectivity of coconut water and IAA (Indole‑3‑acetic acid) application on various concentration as the growth regulator for tribulus growth on thein vitroand its effect toward observation variables. The material used were cotyledon from tribulus embryo and MS (Murashige and Skoog) medium. The research method used a Completely Randomized Design with first factor of coconut water concentration of 0 mL L-1, 50 mL L-1, 100 mL L-1, and 150 mL L-1and IAA concentration of 0 ppm, 0.15 ppm, 0.20 ppm, and 0.25 ppm as the second factor. Observed variables were shoots emergence time, number of shoots, shoot height, number of leaves, roots emergence time, number of roots and regression between observation variables. The result showed that the combination of 150 mL L-1coconut water and 0.25 ppm IAA gave the highest shoot height, roots emergence time, and number of roots. Coconut water treatment on 150 mL L-1concentration alone gave the best result on shoots emergence time, number of shoots, and number of leaves, while IAA concentration of 0.25 ppm independently gave the highest number of leaves. Regression analysis result indicate that the number of roots has a positive correlation with shoots height, number of shoots and number of leaves.

Intensity and spectral quality of the radiation can be manipulated with the use of neutral or color shading screens in growing plants, and it can promote physiological and morphological changes. Therefore, the purpose was evaluating the effects of different shading levels, screens spectral quality, and spacing in the development of cv. Jungle King and cv. Jungle Queen gingers. Rhizomes were planted in 5 cultivation environments (full sun, black screen 50%, black screen 30%, blue screen 50% and red screen 50% shading) and 2 spacing (0.8 x 1.0 m and 0.8 x 1.5 m). The experimental design was completely randomized in a factorial 5x2x2x7, with 5 environments of cultivation, 2 cultivars, 2 spacing between plants and 7 times of evaluation (55, 120, 200, 255, 285, 335 e 370 days after planting (DAP)). The evaluations were shooting index, number of shoots per plant, shoot height and number of leaves per shoot. Shooting of cv. Jungle Queen was earlier compared to cv. Jungle King. Spacing did not influence in the initial development of plants. Screens with 50% shading, in blue or red colors, enhanced alpinia development.

ABSTRAK<br />Tanaman kemukus (Piper cubeba LINN.) sudah dikenal sejak<br />jaman dahulu sebagai tanaman obat, rempah, pengharum dan penyedap<br />masakan. Di Jawa Tengah perbanyakan tanaman kemukus pada umumnya<br />dilakukan melalui setek panjang yang terdiri dari 8 - 14 ruas. Perbanyakan<br />dengan cara demikian dianggap tidak ekonomis, oleh karena itu perlu<br />dicari cara perbanyakan yang efisien dan efektif. Percobaan pengaruh<br />macam setek dan komposisi media tumbuh terhadap daya tumbuh dan<br />vigor bibit dilakukan dengan tujuan untuk mendapatkan teknologi<br />perbanyakan kemukus. Percobaan dilakukan di Kebun Percobaan<br />Cimanggu, Balai Penelitian Tanaman Rempah dan Obat Bogor dari bulan<br />September sampai dengan Desember 2003. Percobaan menggunakan<br />rancangan acak kelompok yang disusun secara faktorial dengan 2 faktor<br />dan 3 ulangan. Sebagai faktor pertama adalah 3 macam setek pendek 3<br />ruas yaitu : (1) setek bertapak, (2) setek sulur panjat dan (3) setek cabang<br />buah. Faktor kedua adalah tiga perlakuan komposisi media tumbuh terdiri<br />dari (tanah + pupuk kandang + pasir) dengan perbandingan: (a) 1:1:1, (b)<br />2:1:1, dan (c) 3:1:1. Media dimasukkan ke dalam polibag ukuran 10 x 12<br />cm. Variabel yang diamati meliputi persentase daya tumbuh, panjang<br />tunas, jumlah daun, bobot kering tunas, jumlah akar, panjang akar dan<br />bobot kering akar. Hasil percobaan menunjukkan bahwa vigor bibit yang<br />diekspresikan oleh persentase daya tumbuh, pertumbuhan tunas dan akar<br />tidak nyata dipengaruhi oleh interaksi jenis setek dan komposisi media<br />tumbuh. Jenis setek berpangaruh nyata terhadap semua variabel yang<br />diamati, kecuali terhadap jumlah daun. Jenis setek yang berasal dari setek<br />bertapak dan sulur panjat manghasilkan persentase daya tumbuh 68,40%<br />dan 62,00%, panjang tunas 2,87 cm dan 4,70 cm, bobot kering tunas 0,13<br />g dan 0,14 g, jumlah akar 5,95 dan 5,76 dan bobot kering akar 0,05 g dan<br />0.05 g, lebih baik dibandingkan setek cabang buah. Jenis media tumbuh<br />hanya berpengaruh nyata terhadap bobot kering tunas tapi tidak<br />berpengruh nyata terhadap variabel lainnya. Bobot kering tunas yang<br />terbaik didapat pada komposisi media tumbuh tanah + pupuk kandang +<br />pasir (1 : 1 : 1) (0,14 g) dan terendah pada komposisi media tumbuh tanah<br />+ pupuk kandang + pasir (3 : 1 : 1) (0.11 g).<br />Kata kunci : Kemukus, Piper cubeba LINN, bahan tanaman, macam<br />setek, media tumbuh, daya tumbuh, Jawa Barat<br />ABSTRACT<br />Effect of cutting materials and growth media on the<br />growth of cubeba cuttings<br />In Indonesia, cubeba pepper plant (Piper cubeba LINN) has been<br />known for years as a traditional medicine, spice, fragrant, and seasonings.<br />In Central of Java, it is usually propagated by using eight or fourteen node<br />cuttings which is not an economical practice. The research on cutting<br />materials and growth media was conducted in Cimanggu Experimental<br />Garden of the Indonesian Spice and Medicinal Crops Research Institute<br />from September to December 2003. The objective of the research was to<br />find out an appropriate propagation technology of cubeba. The research<br />used two factors and three replications which was arranged in a<br />randomized completely block design. The first factor was three kinds of<br />cutting nodes, i.e. (1) attached-rooted cuttings (2) vegetative branch and<br />(3) generative branch. The second factor was three kinds of media<br />compositions of soil, dung manure and sand (1) 1:1:1, (2) 2:1:1 and (3)<br />3:1:1. Observations were conducted on the percentage of budding, length<br />of bud, number of leaves, number of roots, length of root, dry weight of<br />the roots, and the shoot. The results of the research indicated that the vigor<br />of seedlings which was expressed by germination percentage, growth of<br />seedlings, and growth of root, did not significantly affected by the<br />interaction between kinds of cuttings and media composition. However,<br />the kinds of cuttings significantly affected all variables, except the number<br />of leaves. Cubeba seedlings originated from attached-rooted cuttings and<br />vegetative branch had higher germination percentage i.e. 68.40% and<br />62.00%, length of shoot 2.87 cm and 4.70 cm, dry weight of shoot 0.13 g<br />and 0.14 g, number of roots 5.95 and 5.76, length of root 7.32 cm and 7.27<br />cm, and dry weight of root 0.05 g and 0.05 g, compared to the cubeba<br />seedlings originated from generative branch. Media composition was<br />significantly effected only on dry weight of shoots. The highest dry weight<br />of shoot was resulted from composition of soil, dung manure and sand<br />1:1;1 (0.14 g), while the lowest was found on ratio media composition of<br />soil, dung manure and sand 3:1:1 (0.11g).<br />Key words : Cubeba, Piper cubeba LINN, plant material, cutting<br />materials, growth media, growth, West Java

Propagation of jasmine plants by cuttings often experience obstacles, especially to grow roots. Proper planting media and application of growth regulators (PGR) have an important role in the growth and development of plant cuttings roots. The purpose of this study was to determine the effect of planting media types and PGR on the growth of jasmine cuttings. This research was conducted in the experimental garden of the Faculty of Agriculture, Teuku Umar University, in March - May 2019. This study used a completely randomized design (CRD) with a factorial pattern of 3x3 with three replications. The treatment factors studied were (1) the type of planting media consisted of 3 levels namely alluvial soil, sand and husk charcoal, and (2) the type of growth regulator (ZPT) consisted of 3 levels namely control (without zpt), chemical (growtone) and organic (shallot extract). F test results on the analysis of variance showed that the planting medium had a very significant effect on the number of shoots 35 and 45 HST, number of leaves 15, 35 and 45 HST number of roots, root length, percentage of live cuttings. But the planting media had no significant effect on the number of shoots of 15 DAP. Growth regulator substances have a very significant effect on the number of shoots 35 HST, number of leaves 15, 35 and 45 HST, number of roots and root length. Significantly affect the number of shoots 45 HST and percentage of live cuttings, but no significant effect on the number of shoots 15 HST. This shows that the difference in growth of jasmine plant cuttings due to different planting media does not depend on growth regulators, and vice versa.

The research entitled "The Effect of Concentration and Soaking Time of Pepper Cutters (Piper nigrum) in a Solution of Growth Regulatory Substances (auxin)" was carried out. Research was held on April – July 2020 in Green House of Agriculture Faculty, Tunas Pembangunan University, Jl. Balekambang Lor No. 1 Manahan, Surakarta. This study used a factorial experimental method based on a completely randomized design (CRD) consisting of 2 factors as treatment and 3 replications. The first factor, the concentration of growth regulators (auxin) (K), is divided into 3 levels, namely: 100 ppm (K1), 200 ppm (K2) and 300 ppm (K3); while the second factor, immersion time (P), also consists of 4 levels, namely: 2 hours (P1), 2.5 hours (P2), 3 hours (P3) and 3.5 hours (P4). The parameters observed in this study amounted to 9, with details as follows: Number of shoots, number of leaves, length of shoots, fresh and dry weight of shoots, number and length of roots, fresh weight and root dry weight. Based on the results of research on pepper cuttings due to the concentration of growth regulators (auxin) and the duration of immersion, the results showed that: Soaking time had a significant effect on the observed parameters, namely plant length in P2 treatment (2.5 hours). And it did not affect the parameters of the number of shoots, number of leaves, fresh and dry weight of shoots, number and length of roots, fresh weight and root dry weight.
