Abstract

The aims of this research are to identify the dominant type of pest that attack mustard plants, to identify the component of liquid smoke of oil palm empty fruit bunches, to examine the effects of interaction between concentration level and frequency of application of liquid smoke spraying to the intensity of leaf damaging pests attack on mustard plants, to examine the effects of some concentration level and frequency of application of liquid smoke spraying severally to the intensity of leaf damaging pests attack on mustard plants, and to determine effective concentration and frequency of application of liquid smoke spraying to decrease the intensity of leaf damaging pests attack mustard plants. The research results showed that leaf damaging pests found have attacked mustard plants during the research period are Plutella xylostella L., Spodoptera litura, long caterpillar (Plusia spp.), and Crocidolomia binotalis. The test result for chemical content showed that liquid smoke of oil palm empty fruit bunches contained 20 types of chemical compounds.  The compounds with the most content found are Ethylene glycol, Acetic Acid, Phenol/Benzenol & Benzene sulfonic acid/Carbamic acid, Acetone, and Butyrolactone with each successive concentration, i.e. 52,06 %, 22,67 %, 7,76 %, 4,67 %, and 2,77 %, where it is known that phenol and acetic acid are compounds that can play a role as insecticides for pests. The effect of treatments (liquid smoke concentration, spraying frequency, and their interaction) is very real different compared to without treatment spraying liquid smoke solution (control), while the effect of concentrations (2,5ml/l;5ml/l;7,5ml/l;10ml/l) of liquid smoke and spraying frequency (once, twice, and three times a week) and their interaction severally has no real effect, giving treatments (concentration and spraying frequency of liquid smoke) decrease the intensity of pests attack for 24,83%, increase the number of leaves for 8,36%, fresh weight of plants for 127,39%, and shoot-root ratio (SRR) for 44,62%.

Abstract

An epilithic benthic algae functions as a primary producer living on rock substrates. The Autotrofic Index (AI) was measured to understand the level of water pollutions by quantifying an autotrofy organism. This research determined water quality of Pitap river based on the autotrofic level of an epilithic benthic algae and to understand the correlation between the autotrofic level and physicochemical parameters. The measurement of water quality based on Ash-Free Dry Mass (AFDM), the amount of chlorophyll-a and physicochemical parameters were taken every month with two repetitions on September and October 2014. Five sampling sites were selected using a purposive sampling method based on the variety of environmental conditions around the Pitap river. The results showed that the water quality in the upstream (Ajung and Langkap villages) were classified non-pollution (dominated by autotrof compounds) until less pollution (dominated by autotrof-heterotof compounds). Other locations in downstream (Tebing Tinggi, Sungsum and Juuh villages) were determined pollution of water quality by dominance of autotrof-heterotrof components to dominance by heterotof components. Spearman correlation explained that autotrofic index on September 2014 was closely correlated with water temperature and water velocity with their value are 0,954 and -0,794 at significantly α=0,01. On October 2014 water temperature was closely correlated with its value 0,681 at significantly α=0,05.

Abstract

One of the impacts of reclamation of swamps is poison substances in the water channels, which can cause to pyrite oxidation, sedimentation and accumulation of toxic substances in secondary channels. The reclamation channel unit in Semangat Karya Village has a water pH of ± 3 and has the iron level of 4.95 mg / l. Based on South Kalimantan Provincial Governor Regulation Year 2007, pH grade and iron concentration are over the quality standard, while the water is consumed by the residents for everyday intentions. One of the technologies that are applied to increase the pH and to minimize the concentration of iron (Fe) is constructed wetland with the horizontal sub-surface flow (CW-HSSF).  The objectives of this research were to study the dynamics of pH and Fe in the media acid sulfate soils mixed with organic fertilizer (bokashi) 10% at CW-HSSF  system using  Purun Tikus (Eleocharis dulcis) and Kalakai (Stenochlaena palustris). The conclusion of this research indicated that pH value and absorption of Fe in CW-HSSF using Purun Tikus (Eleocharis dulcis) was better than Kalakai (Stenochlaena palustris).

Abstract

Soybean is categorized as a plant which sensitive to water deficit or surplus in its life cycle. If water requirement is not sufficient for the growth and development, the soybean will be subjected to stress. Water stress, such deficiency or excess of water in the plant environment is a condition that disrupts the balance of plant growth. Therefore, it is necessary to observe the interaction between drought stress at various growth stages and soybean varieties, and observe which growth stages that would provide the highest yield of soybean know the differences in drought stress in various stadia of plant growth on the growth and yield of two varieties of soybean crops and which currently can give the highest yield in various stadia grow. This research was carried out by using polybag in the greenhouse of Faculty of Agriculture Universitas Lambung Mangkurat Banjarbaru for 4 months from March to June 2017. The experimental design was Randomized Completely Design with Split Plot Design Factorial. The first factor is soybean varieties (V) as main plot, i.e. Grobogan (v1) and Anjasmoro (v2), and the second factor is the growth stages those subjected to drought stress (C) as subplot, i.e. c1 : vegetative stage 3 (29 DAS and 36 DAS), c2 : flowering stage (35 DAS and 46 DAS), c3 pods appearance/emergence (42 DAS and 53 DAS), and c4 : pods filling stage (68 DAS and 76 DAS). The treatment was repeated 3 times and each experiment unit consists of 5 polybags, thus there were 120 plants in total. The crop growth rate, number of main branch nodes, number of effective root nodules, shoot root ratio, the first flowering time, the harvest time, number of pods per plant, number of seed per plant, 100 seed dry weight, and the number of dry seed per plant. The result showed there was no interaction effect between drought stress in various stages and soybean varieties on all variables. Drought stress at vegetative stage 3 (c1) caused the number of main branch nodes, the number of pods per plant, the number of seed per plant, the 100 seed dry weight and the number of dry seed per plant are lower if they are compared to the plants those subjected to drought stress at pod filling stage (c4). Nevertheless, those variables were not different at drought stress at flowering stage (c2), pods appearance (c3) and pod filling stage  (4). Soybean varieties observation showed that the Grobogan were faster in flowering time and higher in crop growth (26.49 DAS and 3.08 g d-1 respectively) compared to the Anjasmoro (34.08 DAS and 2.73 g d-1 respectively).

Abstract

Agarwood has so high value that can trigger an excessive agarwood encroachment in nature; it threatened the agarwood availability. Agarwood cultivation was the right solution to overcome the Agarwood insufficiency. Currently, bioserum has been found to form Agarwood rapidly. It was found by Kusnadi and introduced to the public by BPDASHLWSS (The watershed management and protection forest inquiry). The formation and effectiveness process of bioserum has not been researched yet scientifically. Therefore, this study aimed to determine the success rate of Agarwood formation and the quality of Agarwood with combined injections treatments on tree branches of Aquilariamalaccensis. This research used a complete randomized design with 3 treatments. Each treatment consisted of several vertical injection hole spaces: 5 cm, 10 cm, and 15 cm. The horizontal space for these three treatments was the same, 5 cm.  The result showed that the best vertical range of injection was 10 cm. Therefore, each injection hole would produce separate agarwood chips. A 10-cm vertical range injection also made the rest wood between the injection holes not too wide. This Agarwood was classified into kamedangan class with the average weight of 2 g/chips.

Abstract

Seagrass is one of the important ecosystems in shallow coastal and marine waters, because it has many roles, both ecologically and economically. Bontang City is one area that has a vast seagrass ecosystem. Management of seagrass ecosystems in Bontang City, of course, wants the existence of sustainable economic development, but on the other hand, sometimes increasing economic needs based on natural resources (resource base), often create a dilemma for the sustainability of natural resources. This happens because the consumption needs of the community are often not supported by good planning and management in utilizing natural resources so that the deterioration of environmental quality is often seen as a cost that must be paid in a process of economic development. The purposes of this study are 1). Identifying forms of utilization from seagrass ecosystems, 2) knowing the economic value of seagrass ecosystems. The sampling method used was purposive sampling. The results of the study revealed that fishing activities with splint catches and nets were a form of seagrass ecosystem utilization activities. Based on the results of data analysis, it is known that the total economic value of 4 (four) utilization of seagrass ecosystems in Bontang City is Rp. 7,081,050,816,042 per year. The utilization value with the largest proportion comes from the value of indirect benefits which is equal to 95.66%, and the lowest proportion is the option value.
