Abstract

The research aim was to find out the effect of seed scarification and germination substrate upon seed viability and seedling vigor of aren.  The research applied a randomized block design with factorial pattern consisting of two factors.  The first factor was scarification treatment: without scarification, scarification at 400C, scarification at 400C and soaked in 0.5% KNO3 solution for 36 hours.  The second factor was germination substrate:  sand, rice hull coal, cocopith, mixture of soil taken from natural palm growth area and organic material at a ratio 1:1, and mixture of 1 g NPK fertilizer with 1 kg soil taken from palm tree forest area and organic material media.  The greatest seed germination of 83.33–86.67% with germinating speed of 0.85-1.04 %etmal was found in the scarification at 400C soaking in 0.5% KNO3 solution for 36 hours and soil organic and matter treatment. This treatment also resulted in normal vigorous seed indicated by higher dry content weight and hypothetic vigor index than any other treatments.

Abstract

The aim of the research was to identify the suitability of fried onion industry.  The research was carried out in 2007.  Samples of the fried onion industry in Palu were determined using a census method by taking all 17 fried onion industrial units existed in Donggala district. Analysis methods used were Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate Return (IRR). The research results showed that based on production multiplication the fried onion industry returns was 19,500 kg year-1 with fried onion selling price of IDR 70,000 kg-1. Thus, the average of returns obtained was IDR 7,665,000year-1. The fried onion industry was financially suitable to be run and developed as indicated by NPV value of IDR 10,406,415,482, BCR value of 1.61, and IRR value of 576.13% or in other words NPV>0, BCR>1 and IRR>12.30%. The industry benefit obtained from the difference between the returns and costs was IDR 3,056,587,500 year-1 or IDR 245,715,625 month-1.  Factors affecting the industry benefit were the production quantity and costs spent for production facilities

Abstract

The research aimed to identify the physico-chemical and sensory characteristics of aren instant starch noodle (ISN) substituted with 0, 5, 10, 15, 20, and 25% of tapioca starch.  The physicochemical and sensory characteristics observed were gelatinization level, water content, white degree, cooking rate, cooking loss, tensile strength, elongation, texture, performance, aroma, taste and viscosity.  Corn ISN was used as a comparison. The research results showed that the percentage of the tapioca starch that could substitute the aren starch was in the ranges of 5 – 20%.  Substituting with 20% tapioca starch could yield ISN most similar to the corn ISN in which physicochemical and sensory characteristics were acceptable to consumers.  However, the water content of the ISN resulted from the research still higher than that of standard category, therefore the time length for drying need to be prolonged.

Abstract

The Objective of the study was to identify microhabitat characteristics in natural nesting ground as a basic form of egg hatching of maleo birds for ex-situ habitat in Lore Lindu National Park. Survey methods and experimental design were applied in this study using Saluki Nesting Ground as a habitat model. In a natural habitat, variables observed were microclimate condition (temperature and humidity, depth and diameter of holes) while in an artificial habitat where four different forms of eggs hatching (in-situ, ex-situ, incubator by means of media rack and sand) were applied temperature, humidity, hatching quality, incubation time, hatching weigh, and mortality were determined. Data analysis applied was descriptive analysis and multivariate test using SPSS computer program. Results of the study showed that in the natural nesting ground the temperature ranged from 30 to 35 oC with an average temperature of 33.03oC, and the humidity from 60.20 to 71.10% with an average humidity of 68.55%. The hole diameter ranged from 28-63 cm with an average hole diameter of 41.64 cm and the hole depth from 51-87cm with an average hole depth of 63.29 cm. The application of hatching method was resulted in the in-situ temperature and humidity of 32.90 oC and 68.41%, respectively, and the ex-situ of 31.68 oC and 67.52%, respectively, rack incubator of 33.99 oC and 70.06%, respectively, and sand incubator of 33.78 oC and 71.02%, respectively. The longest incubation time was found in the ex-situ semi natural hatchery which was 78.40 days, followed by the in-situ habitat 63.48 days, rack incubator 59.40 days, and sand incubator 59.33 days. The best hatching quality was found in the rack incubator, but the mortality rate was highest. The application of incubator for egg hatching of maleo birds could reduce the incubation time length and increase the hatching quality

Abstract

The aim of the research was to determine the physiological ripen time of mengkudu seed based on penology study. The study was conducted in the Green House and Experimental Farm of Jurusan Biologi FMIPA Universitas Negeri Makassar (UNM). Penological observation was done since the beginning of flowering until the fruit formation was completed and mature. The experiment conducted used three trees, in each tree three branches with all their blossoming flowers were labeled for observation.  Therefore, there were 3 x 3 = 9 branches including their flowers were observed for the flower transformations and development, fruit formation and fruit maturity stages. There were three stages found for the mengkudu fruit to reach maturity.  Such stages were stage M-1 (perfectly           fruit formation), stage M-2 (morphological mature), and stage M-3 (physiological mature). Based on visual observation, the exocarp changes were followed by mesocarp (fruit meat) and endocarp            (seed skin) transformations.

Abstract

The study was conducted at the eksperimental station Kawatuna  Sub District, Palu City, Central Sulawesi Province from January 2002 until Mei 2002. Thirty four of non pregnant Palu Local sheep were used.  The sheep were  devided in two groups; the first group consisted of 17 ewes were prepared for natural mating, whereas the second group for artificial mating.  Both groups were estrus induced using intramuscularly injection of 1,25 cc PGF2µ (reprodin) per ewe. Two days after application of PGF2µ when the animal showed estrus, the natural mating and artificial insemination were conducted. The research results showed that the mating method significantly affected (P<0,05) on successful pregnancy. The artificial insemination method produced hingher number of pregnancy than the natural mating. The conception rate of the Palu Local sheep that mating by artificial insemination were 12 sheep (80 %) compared to only 6 sheep (40 %) by natural method
