Abstract

Experiment was conducted on shallow peat with depth (50 - 75 cm) and C/D flooding type at Purwodadi village, Maliku District, Pulang Pisau Regency, Central Kalimantan in wet season 2003.  Ten samples were taken from areal of 2 ha for studying characteristics of shallow peat.  Nutrient absorption of crops and soil nutrient after harvesting  were also analyzed.  This experiment used split plot design with three replications.  As a main plot was input application (M1) : manure (5.000 kg/ha), lime (2.000 kg/ha), urea (150 kg/ha), SP36 (312.5 kg/ha) and KCl (200 kg/ha) for tomato and SP36 (187.5 kg/ha) and KCl (125 kg/ha) for red pepper and without application (M0). Five varities of red pepper (Tombak 1, Tanjung 1, Tanjung 2, Prabu and Hot Chilli) and, five varities of tomato (Oval, Ratna, Mirah, Berlian and Permata) were as subplots. The results showed that soil chemical characteristics were : peat depth 50 - 75 cm, phyrite depth 75 - 100 cm, soil pH 3.5 - 4.0, C-organic content 12 - 24 %; range of nutrient availability : N (0.4 - 0.6 %), P (30 - 50 ppm P), K (0.1 - 0.3 me/100 g), Ca (1 - 6 me/100 g), Mg (0 - 1 me/100 g), Fe (20 - 120 ppm Fe) and Al (1 - 7 me/100 g).  Availability of nutrients N, P, K, Ca, and Mg was low, and it could be increased by application of some inputs such as manure, lime, urea, SP36 and KCl.  Low nutrient availability and crop absorption especially K, Ca, and Mg was a main factor that retarded crop growth.  Red  pepper and tomato yields ranged 0.59 - 4.02 and 4.77 - 10.99 t/ha for control treatments and 3.44 - 7.72 and 14.85 - 35.98 t/ha with input application.   Key words : amelioration, yield potency, red pepper, tomato, shallow peat

Abstract

The objective of this research was to obtain haploid hot pepper plants by inducing gynogenesis with g-ray irradiated pollen for pollination. Fruits resulted from pollination by irradiated pollen was used as the explants of the in vitro culture in solid MS medium containing BAP, IAA and GA3. The resulted plants then cultivated in MS0 medium. The result of the research showed that hot pepper immature embryo could grow and developed into whole plant when the age of this embryo was 9 days after pollination or more. The haploid hot pepper plants can be obtained by pollinating the pistil with 10 Gy irradiated pollen. The MS medium containing BAP 0.3 + IAA 0.2 + GA3 0.5 mg/l and BAP 0.4 + IAA 0.1 + GA3 0.5 mg/l supported well the development of immature embryo into whole plants. The growth of haploid hot pepper plants was slower than that of diploid ones.   Key words:  Hot pepper, haploid plant, gynogenesis, g-ray.

Abstract

The effect of different dimentions on field ditch to soil chemical changes under soybean planting at acid sulphate soil was being studied at wet season 2001. The experiment used split plot design with 3 replications. Inter field ditch spacing as a main plot consisted of 3, 6 and 9 m. Field ditch depth as a sub plot consisted of 20 and 40 cm. The result showed that space of field ditch 7.5 m and 20 cm of depth could improve soil chemical (pH, Al-dd, Fe-dd, SO, N, P), increased growth and yield of soybean.   Key words.. Field ditch, Soybean, Acid sulphate soil

Abstract

Nunukan chicken is local chicken of Tarakan and Nunukan in East Borneo Province. It is a germplasmof East Kalimantan which have special characteristics. Due to its characteristic, the chicken extremelyneed to be conserved and develop. This study was conducted to find out more reliable data on thecharacteristics of nunukan chicken in Tarakan Island. It was done by directly observed and measuredfenotype traits of nunukan chicken. Sample used was mature chicken, with the total tnumber 211 birds.Fenotype qualitative traits of nunukan chicken was florid brown of feather basic colour, columbian offeather colour theme, golden of feather flickering, and solid of feather pattern. The other special traits islittle growth (even not growth) of wings and tail feather, and on immature chicken (age of 0-5 month)commonly primary feather not growth. There was 13 fenotype quantitative traits on male, and two onfemale chicken was different between location (sub district) on 20 traits. The number of nunukan chickenat Tarakan Island was about 940 birds, and 36,17% was mature chicken. The effective population totalwas 299 birds, highest effective population was in West Tarakan (162 birds) and lowest was in MidleTarakan (46 birds). The average of inbreeding increased 0.177%, highest was in Midle Tarakan (1,08%)and lowest was in West Tarakan (0,31). The population of nunukan chicken in Tarakan Island was specificof the fenotype characteristic.

Abstract

Have been done a research which aim to know the pH and optimal sugar concentration at process of forming nata from cocoa seed dilution waste. Method used in this research experiment method by 16 treatment. Design was using a “Completely Randomized with composed of factorial” or Factorial RAL. The first factor is sugar concentration and secondary factor is acidity level (pH). The result of research indicate that formed by nata and thick and also different rendemen at all of given treatment. The treatment which is best is interaction sugar concentration 5% with pH 4 in thick forming nata that is 0,60 cm. and heavy rendemen nata of equal to 25,65%. Cocoa seed dilution waste result of fermentation can be made a alternative for the making of nata. Key words : Fermentation waste, Theobroma cacao, Nata

Microorganism characterization specially khamir is life cocoa fruit have been conducted. This research use inventarization method and identify to determine khamir species or genus which pursuant to monograph (Kreger-Van Rij, 1987 and Kurtzman, 1998). This research conducted by 3 regency (Regency Donggala; Parigi Moutong; Toli-Toli) in Central Sulawesi.Result of obtained research depict that khamir group which life cocoa fruit in Central Sulawesi is same, this matter proved from result of inventarization and identify which obtained by every regency much the same to its type. Regency Donggala obtained 4 isolate with result identify Rhodotorula sp. (DB.K112), Debaryomyces hansenii (DB.K221), Candida parapsilosis (DB.K233), and Saccharomyces cerevisiae (DB.K342). Regency Parigi Moutong also obtained by 4 isolate with result identify Saccharomyces cerevisiae (PM.K113), Candida parapsilosis (PM.K122), Rhodotorula sp. (PM.K231), and Trichosporon cutaneum (PM.K343). Regency Toli-Toli obtained 6 isolate with result identify Candida parapsilosis (TL.K112), Debaryomyces hansenii (TL.K223), Saccharomyces cerevisiae (TL.K231), Trichosporon cutaneum (TL.K242), Saccharomyces cerevisiae (TL.K351), and Rhodotorula sp.

Abstract

The study of "The Effect of Solvent Preservative Against Security To Save Oleander Flowers (Nerium oleander L.)" was held from March to April 2011 which aims to identify and study the effect of preservative solutions on postharvest quality of cut flowers Oleander (Nerium oleander L.). The research method used is an experiment with 14 treatments and 3 replications. The design used was the design (CRD) with factorial pattern factor of sucrose concentration and immersion time. The results showed that the resistance to keep, the number of blooming flowers, flowers wither, and the volume of water absorption is best at a concentration of 5% with 2 hours soaking time compared with other treatments.
