Abstract

Abstact Wheat flour biscuits mixed with local food starch is a development of food security. Generally flour and starch contain amylose and amylopectin with different amount composition. Mixing of wheat flour and some starch is tacca tuber starch, tapioca starch (sweet potato), starch sago starch and corn starch form different amylose and amylopetin content composition. Comparison of amylose and amylopectin levels affects texture, sensory properties and gelatinization temperature. This study aims to evaluate the physical characteristics of blending wheat flour with tacca starch (anuwun), cassava tuber starch, sago starch and corn starch, mixing function of starch and starch in forming sensory properties of biscuit. This study used Completely Randomized Design (RAL) with mixed flour and starch mixed flour treatment with 1: 1 ratio. All treatments were repeated 3 replications and the data were analyzed. The results of the most favorite aroma-level test on TTPT treatment, the highest color in TTPS treatment, the highest taste in TTPJ treatment and crispness in TTPJ treatment. Diversity of high level of preferences on biscuits of TTPS composite flour. The level of preference for the crispity of the TTPJ composite flour biscuit obtains the highest value that is consistent with the ranking of biscuit hardness. Each composite flour has different solubility characteristics and water absorption.

ABSTRACTThis study aims to identify internal factors and external factors, and to determine the development strategy of the bamboo handicraft home industry in Kinilow. The study was conducted from March to May 2017. The data used were primary and secondary data. Primary data is obtained through observation and interviews that are divided into two parties: internal party (bamboo handicraft business owner) with 6 (six) respondents who produce and sell bamboo handicrafts, and external parties (local government and consumers). Whereas, secondary data obtained from literature study. Data analysis used is by using SWOT analysis.The results showed that the internal factors include: Raw materials are easy to obtain, relatively cheap raw material prices, good raw material quality, highly skilled manpower, have followed skills training activities, personal capital use, fast production process, difficulty level Low cost, long-lasting product, affordable selling price, not yet have financial record, not yet relationship with financial institution, traditional production equipment, not yet product promotion method through media (online / print), absence of machine use in Production process (technology), No motorized parking space, and Product display is not good. While external factors include: Increased demand from overseas buyers with TIFF event in Tomohon city, Increased demand from local people, Opportunity for exhibition, Potential and market opportunity is wide, Lack of interest of young generation to work in continuing and maintaining bamboo handicraft business, The existence of new competitor in SULUT, the high of substitution with plastic raw material, unsafe business place from landslide disaster, The existence of discourse from government to relocate place.Based on the SWOT diagram, the chosen strategy is a combination of SO strategies: 1) Developing bamboo handicraft products in Kinilow by innovating to create or produce new bamboo handicraft products, 2) Cooperate with the government to keep expanding Network marketing or marketing area.Keywords : Household Industry, Bamboo Handicraft, SWOT.

The plant material used is potato plant varieties Granola. The treatments werePlant Spacing (90 cm × 30 cm), Plant Spacing (70 cm × 30 cm) and Plant Spacing(50 cm × 30 cm). Variable observations include: 1) liniear growth rate, 2) longgrowing period and 3) maximum dry weight of the potato plant. The data obtainedwere analyzed by using the Least Significance Difference (LSD) 5%. The resultsshowed that plant spacing treatment had an effect on linear growth rate andmaximum dry weight of plant crop. While the best spacing for potato plants is plantspacing of 90 cm × 30 cm.Keywords: the potatos, medium plains, plant spacing

Abstract

ABSTRACTSoursop fruit is a tropical plant that is well known by Indonesians. This is a fruit nutritious fruit plant, that is not only used as fresh food but can be processed into jelly candy. The aim of this study was to obtain an appropriate concentrations of sugar (sucroce) additions on the jelly candy processing based on, panelist responds on sensory dest of the jelly candy. The study was conducted using a completely randomized design with five treatments, including A (sucrose 20%), B (sucrose 25%), C (sucrose 30%), D (sucrose 35%), and E (sucrose 40%). The parameters analyzed were sensory, plasticity, moisture content, sucrose content, and vitamin C. The results showed that the C treatment (sucrose 30%) was the most favorable, on this treatment contains of 17.52% average moisture content, 44.51% average sucrose content, 21.90 mg/100 g average vitamin C content and 80.44 mm/g/s average plasticity content, respectively.Keywords: jelly candy, sucrose, soursop

Abstract

ABSTRACT Sweetened dried citrus peel is a product from citrus peel as an effort to give value to citrus’ by-products and food diversification as a new food product. This research was aimed to analyze the chemical characteristics as influenced by duration of drying and to evaluate the panelists’ preference level of sweetened dried citrus peel. Complete Randomized Design (CDR) was the statistical analysis of this research and durations of drying as the treatment. Results showed that moisture content of sweetened dried citrus peel were ranged from 10-84% - 15,34% and they were significantly different among treatments. The temperature used during drying process in this research was 700C The highest moisture content was in treatment A (4 h drying), whilst the lowest was in treatment D (7 h drying). The total sugar were ranged from 74,51% (treatment D, 7 h drying) - 79,27% (treatment A, 4 h drying). Vitamin C content in all treatments was ranged between 14,58 – 14,63 mg/100g. Based on the preference level, the most preferable sweetened dried citrus peel was resulted from 6 h drying with the value for aroma, colour, taste, and texture were 3.56 (neutral), 4.04 (like), 3.36 (neutral), and 3.56 (neutral), respectively.Keywords: sweetened dried citrus peel, duration of drying

Abstract

ABSTRACT Extreme climate change is one of the factors that determine the quality of the plant. In this case one of the main factors driving plants to photosynthesise is light. (Alhadi, 2016). In general, the provision of ideal conditions is still limited to the protection of plants from extreme weather using greenhouse or better known as the greenhouse or plant house. Plant house is one way to provide an environment closer to the optimum conditions for plant growth. According to (Fides, 1992) the addition of artificial light to create long day conditions in the equator area of about 3-4 hours with the intensity of light with a range of 32-108 lux. Long day manipulations can be made using light from both incandescent and tube lamp sources (Kofranek, 1980). The purpose of this research is to study the substitution of sunlight with HID (High Intensity Discharge) lamp and LED (Light Emiting Diode) to optimize the growth of Cherry tomato plant in tropical plant house made from polyethylene (PE) roof. The results showed that the total intensity of light inside the plant house was obtained from the total intensity of the incoming sunlight in the plant house plus the total HID light bulb that is equal to 217.86 MJ/ m2 (treatment N2) and total sunlight plus total LED lamp light that is equal to 208.58 MJ / m2 (N3 treatment). But the intensity of this light is still much smaller than the total intensity of light outside the plant house (treatment N0) that is equal to 526.65 MJ / m2
