Abstract

The Special Efforts Program (Upsus) is an Indonesian government program to increase production/productivity of lowland rice to support the realization of food self-sufficiency. The Upsus targets are to increase the planting index by 0.5 and productivity by 0.3 tons/ha/GKP. The increase in planting index is achieved by the expansion of added planting, but the increase in productivity has not been reached optimally due to pest and disease attacks. The objective of this research was to determine the knowledge, attitudes, and actions of Upsus farmers in controlling pests and diseases, rice cultivation techniques, and implementation of Upsus in Karawang District. The research was conducted by distributing questionnaires to 60 farmers in Tempuran and Tirtajaya Sub-District at Karawang District. The respondents were selected by purposive sampling with the consideration of respondent being an active farmer, having at least 5 years of farming experience, and has ben a member of Upsus for at least 1 year. Most respondents have age in the range of 41-60 years, the highest education of elementary school, and have farming experience for 5-10 years. Pests and diseases are the biggest problems faced by the farmers. Upsus farmers used Ciherang and Inpari 32 varieties and the applications of pesticides were conducted according to the schedule. Most of the farmers could not distinguish between pests and diseases. The dominant pest and disease control carried out was the use of chemical pesticides. Keywords: diseases, pesticides, pests, Upsus

Abstract

Cinchona ledgeriana Moens is an industrial plant producing secondary metabolite quinoline alkaloids. To maintain and moreover, to increase the quinoline production especially quinine, in vitro culture system through cell culture could be a potential alternative. If the use of elicitor in cell culture can increase the production of a secondary metabolite, the activity of the enzymes involved in the biosynthetic pathway of the secondary metabolite in question might be increasing. This study aimed to examine the activity of NADPH oxidoreductase in the elicitated cell culture of C. ledgeriana and to evaluate the correlation between the activity of this enzyme and the level of quinine production. The cell cultures of Cinchona were treated with abscisic acid (ABA) or paclobutrazol (PBZ), combined with sucrose, sorbitol, or mannitol in Wood Plant (WP) media, for 7 weeks on a shaker. The quinine concentration was determined using high-performance liquid chromatography (HPLC) and the enzyme activity was measured using fluorometry. The results showed that the highest enzyme activity was found in the P7M cells (PBZ 7 mg/L + mannitol 5.3 g/L + sucrose 20 g/L), followed by the A3S cells (ABA 3 mg/L + sorbitol 5.3 g/L + sucrose 20 g/L). These results correspond to their production level of the quinine alkaloids. The lowest enzyme activity was found in the cultures without elicitor. The increase of NADP(H) enzyme activity in the P7M and A3S treatments were 13.5 and 8.5%, respectively, compared to that in the control cells. Keywords: elicitation, fluorometry, NADP(H) oxidoreductase, quinoline alkaloid

Abstract

The objective of this research was to determine the residual effect of fertilizer and former plant spacing of mungbean first planting on growth and yield of cowpea second planting in a dry land. The experiment was conducted at Muneng Research Field, Probolinggo, East Java during dry season in 2015. The cowpea seeds of KT 5 varieties were planted in plots measuring 4 m x 4,5 m with plant spacing of 40 cm x 15 cm, 2 plants/hole. This research was carried out without adding fertilizer (fertilizer application only given on mungbean planting). This experiment was laid out in a split plot design and replicated three times. Plant spacing of mungbean as the main plot, namely 1) former of 40 cm x 10 cm, 1 plant/hole (J1); 2) former of 40 cm x 15 cm, 2 plants/hole (J2); and 3) former of 40 cm x 20 cm, 2 plants/hole (J3). Residual combination of organic and inorganic fertilizers as the sub plot, namely 1) former without fertilizer (R0); 2) former of 50 kg ZA + 50 kg SP-36 + 100 kg KCl/ha (R1); 3) former of 150 kg Phonska/ha (R2); 4) former of 5000 kg organic fertilizer/ha (R3); and 5) former of 75 kg Phonska + 2500 kg organic fertilizer/ha (R4). The results showed that the cultivation of cowpea with R3 and R4 treatments had effects on shoot and roots dry weights. The highest cowpea yield was obtained with J3 and R4 treatment of 1,62 t/ha and the highest biomass was obtained with J3 treatment of 5,92 t/ha, but statistically not significantly different from the other treatments. Keywords: cowpea, dry land, residual fertilizer

Abstract

Fire on peatlands takes place not only in areas where preparation for cultivation is in progress, but also in areas that have been cultivated, such as for sago palm growing. One of the important factors that influence the vulnerability of cultivated peatlands to fire is the availability and amount of biomass fuel that easily catches fire, such as ferns, grasses, and broadleaved shrubs in their living as well as dead (litter) stages. The present study concerns the vulnerability of peatland utilized for sago growing by smallholders, focused in Tebing Tinggi Timur, Kepulauan Meranti District, Riau Province. The objectives of this study were to analyze the composition and assess the biomass of fire catchers in the sago palm plantation. Data collection was conducted in three locations in Kepau Baru Village. In each location, a 1000 m-long transect line was drawn and 10 sampling plots of 2 m x 2 m were established along the line with 100 m intervals. Results showed that total biomass of fire catchers in this growing system was averaged at 24681 kg/ha, in which the dead plant fraction was predominating (average at 17478 kg/ha or 70.81%) over the living plant fraction (in average 7203 kg/ha or 29.19%). The latter consisted of ferns that averaged at 2.191 kg/ha or 30.42%, grasses (20 kg/ha or 0.28%), non-woody broadleaved shrubs (581 kg/ha or 8.07%), and woody broadleaved shrubs (4411 kg/ha or 61.24%). The amount of fire catchers in relatively large quantities in this plantation system could magnify fire risk during drier months, especially during El-nino years. Keywords: biomass, fire risk, grasses, non-woody broadleaved shrubs, woody broadleaved shrubs

Abstract

Widelia plant (Wedelia trilobata (L) Hitchc) is a spreading herb from the Asterase family that potentially can be used as a ground cover in the roadside greenery because this plant has a faster growing rate and has aesthetic values in both leaves and flowers. The aim of this study was to observe the microclimate of the roadside greenery and the vegetative growth of widelia at three levels of the tree canopy shades in the collector and local roads of Yogyakarta City. The experiment was carried out using an inter-site design (oversite) consisting of two factors, namely road factors (collector roads and local roads) and levels of shade canopy (full > 50%, moderate 20–50% and no shade 0%). The results of the analysis of variance did not show any significant differences on the microclimate and widelia growth parameters on the collector or local roads. The wind speed, noise, and number of vehicles on the collector road showed the higher number compared to those on the local road. The results of analysis of variance in the three levels of tree canopy shade also showed significant differences in microclimate and widelia growth parameters. The lowest light intensity, air temperature, humidity, soil temperature, soil moisture, stolon length, number of leaves, number of shoots, number of segments, and dry weight plants were found in full shade level (> 50%). All observation variables did not show any significant interaction effect between the two types of roads and the three levels of tree shades. Keywords: canopy shade, microclimate, roadside greenery, widelia (Wedelia trilobata (L) Hitchc), Yogyakarta

Abstract

WINS" (Win-Win Strategy) in the management of protected areas is the strategy that benefit both parties. Agroforestry with forest trees accompanied by agricultural crops may benefits the community if it is implemented in line with the management of Meru Betiri National Park (TNMB) policies. The agroforestry plants proposed in this study were aren (Arenga pinnata), java chili (Piper retrofractum), and porang (Amorphophallus muelleri). This study recommends four strategies for better agroforestry practice in TNMB, i.e.,g. 1) strategy I, increasing public awareness of the urgency of the preservation of national park areas; 2) strategy II, formulating policies to support agroforestry as a strategic management effort; 3) strategy III, education and counseling, as a strengthening of the role of extension workers; and 4) strategy IV, facilitating access to relevant data across all participating institutions and is supported in a multidisciplinary manner. This model may be used as a reference for agroforestry models in conservation areas, especially in TNMB, which will optimize the development of native plants in an area. Keywords: agroforestry, Arenga pinnata, Meru Betiri National Park, SWOT analysis, win-win strategy

Abstract

The large number of old, damaged, or dead tea plants cause the plant population per hectare to be low that eventually decreases the productivity. Propagation using the transplantation technique is used for embroidery because it has the advantage of a shorter immature plant period and higher seed size so that it can compensate for the surrounding plants but the weakness of transplantation is low success rate. This study aims to 1) determine the morphological changes of root transplantation and biochemistry on TRI 2025 clone transplantation using cocopeat, husk charcoal, and moss, 2) determine the success rate of transplantation in each medium. This research was conducted in August 2018–January 2019 at the Pagilaran production garden, PT. Pagilaran, Batang, Central Java. Field experiments were prepared using a single factor Completely Randomized Environment Design (CRD). The factors tested were the type of transplantation media, namely the media of husk charcoal, cocopeat, and moss. Observations were made on transplantation root morphology, levels of glucose, sucrose, and total sugar in the transplanted stem bark and the concentration of auxin, gibberellin, and cytokinin in the transplant roots. The data obtained were then analyzed using variance and if there was a significant difference between treatments, the Duncan multiple distance test (DMRT) was continued at the 95% confidence level. The results showed that the type of media had no significant effect on the ability to form glucose, sucrose, and total sugar in the bark. The development of root morphology of cocopeat media was seen to be the highest. The ratio of cytokinin/auxin in cocopeat was the lowest but the highest levels of cytokinin and auxin were found in moss, while cocopeat had the highest level of gibberellin. The highest transplanting success rate was found in moss medium with 58.33%, cocopeat and husk charcoal media had the same success rate, namely 41.60%. Keywords: transplantation, biochemistry, media, success, TRI 2025
