Abstract

The objective of research was to study the effect of concentration and application of palm oil effluent on the growth and production of long bean.  The research was carried out from March to June 2013, at Sebelang Village of Muara Pahu Sub-District, West Kutai Regency.  The Randomised Block Design was employed for the research with factorial 3 x 3 and 3 replications.  The first factor was Liquid Palm Oil Effluent Concentration (D) consisted of 3 sub-factors: 1 ml/crop (d1), 2 ml/crop (d2), and 3 ml/crop (d3).  And the second factor was time of application (W): 10 days after sowing (w1), 20 days after sowing (w2), and 30 days after sowing (w3). Results of the research revealed that: (1) the liquid palm oil effluent concentration did not affect significantly on the crop length at 13, 23, and 33 days, age of crop flowered, age of harvest, number of fruit per crop, fruit length, and production per crop; (2) the time of application did not also affect significantly all parameters observed, namely crop length, age of crop flowered, age of harvest, number of fruit per crop, fruit length, and production per crop; and (3) the interaction between the two above factors also did not affect significantly on all parameters observed.

Abstract

Celery is a commercial plant that should be cultivated. Nutrient Film Technique Hydroponic cultivation systems is one of the technologies that can be applied in a narrow area, but research of the planting medium and the concentration of nutrients in hydroponic cultivation system for celery plants are rare. This study aimed to analyze the influence interaction and single factors planting medium and nutrient concentrations on the growth and yield of celery. The design of this study used split plot design. The main plot were the concentration of nutrients (n): 1200 ppm (n1), 1300 ppm (n2), and 1400 ppm (n3). Subplot were the planting mediums (m): rockwool as control (m0), sawdust (m1), husk fuel (m2), and rice straw (m3). There were twelve combinations, with three replicates. The results showed that treatment interaction was not significant effect on growth and yield, but a single treatment of plant media rockwool and nutrient concentration of 1300 ppm able to increase the growth and yield of celery.

Abstract

The Response of Lettuce (Lactuca sativa L.) to The Types and Application Time of Agroprobiotic Fertilizer. Agroprobiotic fertilizer as an alternative of organic fertilizer is expected to reduce the use of chemical fertilizers.  The aim of the study was to determine:  (1) the best type of agroprobiotic fertilizer; (2) the best application time; (3) interaction between the two factors on the growth and yield of lettuce. The study was conducted from May until July 2018 at  Faculty of Agriculture, Mulawarman University.  The research was 5x2 factorial experiment arranged in Completely Randomized Design with six time replications.  The first factor was the types of agroprobiotic fertilizer, namely: Maknyus; Cimelati; Mayas Putih; Keriting; and Hitam rice. The second factor was the application time of fertilizer, consisted of: in the morning (at 07.00-08.00) and in the afternoon (at 17.00-18.00).  The variables observed consisted of: the increment of plant height and number of leaves increment at 14; 28; 42 days after treatment (DAT); and at harvest time, fresh weight, and leaves area. Data were analyzed by analysis of variance and continued with the Least Significant Difference (LSD) test at 5% level. The results showed that the types of agroprobiotic fertilizer and the interaction between the two factors had no significantly different on the growth and yield of lettuce.  Agroprobiotic fertilizer from Mayas Putih rice showed the better growth and yield than others. The best time for application of fertilizer was in the morning, it showed significantly different on the increment of plant height at harvest time.

Abstract

The post mining soil has generally known for its high acid, poisonous compound and low macro nutrient concentration. (N, P, K, Ca, and Mg).  At this particular soil condition, many of the cultivation plants cannot grow well.  Therefore, a research needs to be conducted in order to repair the post mining soil condition by means of increasing the pH and macro nutrient concentration through calcification and litter addition.   This research had been done in November until December 2012 at the Agronomy Laboratory, Agriculture Faculty of The Mulawarman University used the Complete Random Design of Factorial (RAL) 2 x 5, with 3 times repetition.  The first factor was the Dolomite (D) with 2 levels (d0 = 0 g dolomite/kg soil, and d1 = 6,06 g dolomite/kg soil.  The second factor was the litter (T) with 5 levels (t0 = 0 g/kg soil, t1 = acacia litter (Acacia Mangium Will) 100 g/kg soil, t2 = Arachis pintoi litter Krapov. & W.C. Greg 100 g/kg soil, t3= seashore flower (Wedelia trilobata (L.) Hitchc) litter 100 g/kg soil and T4 = sengon litter (Albizzia Falcataria) 100 g/kg soil.  This research used the Kailan plant (Brassica oleraceae L. var acephala DC).   On the soil which had no dolomite, litter treatment A. Pintoi Krapov.&.K.C.Greg and sengon had positive impact on the pH increase, also for C-organic, N-total, and decreased the C/N value ratio, and Al3+content, followed by the seashore flower litter also influenced positively to the pH, C-organic, N-total increase, and decreased Al3+content.  Acacia influenced positively to the C-organic and N-total also, but negatively influenced the C/N ratio and Fe solubility.  The dolomite treatment with sengon litter gave additional height to the plants, leaves quantity and wide better than other treatment.

Abstract

This study aimed to determine  1) the potential production of aren plant in Kalimantan Timur, (2) the development prospects  and processing industries  aren in Kalimantan Timur. The research was conducted  in the district of Kutai  Kartanegara, Kutai Barat,  and Kutai Timur. Data were collected on primary and secondary data. Sampling methods  purposive sampling  to farmers / producers of aren and a key information as many as 15 people. Data analysis was descriptive statistical analysis, and  SWOT analysis. The results showed that the aren plant in Kalimantan Timur spread over 7 districts  of  Kutai  Timur, Kutai Kartanegara, Kutai Barat, Samarinda, Penajam Paser Utara, Paser, and Bontang.  Counties with the largest aren plantation area is an area of Kutai Barat District 495 ha. Kutai Kartanegara regency area of 363 ha and the Kutai  Timur Regency area of 250 ha.  The district's largest producer of aren plantation in 2011 was as much of Kutai Timur Regency 76.62% of the total production of the aren plantation in Kalimantan Timur aren processing made by farmers / producers of aren in Kalimantan Timur are still confined to the traditional aren processing into brown sugar.  While processing aren into arenga palm sugar  and bioethanol  confined to trials. Effort is made by processing techniques and simple business management and packaging using banana leaf, mahang leaf, and plastic. Based on the SWOT analysis of the brown sugar  development strategies in Kalimantan Timur with 1 . Strategy is to turn around a. conduct intensive palm cultivation with improved varieties ; b. Provide access to capital for farmers / producer ; c . provide business management training ; d.Transfer technology palm cultivation and processing of the results of existing research . 2 . Devenif strategy is to : a. product diversification and modification of packaging ; b expand marketing network ; c. formed a joint venture group that fostered the related department .
