<em>The agricultural sector</em><em> is a strategic sector in Manokwari regency. The agricultural sector provides a major contribution in the regional economy, an economic base of rural people, dominate the life of most residents in this region and provider of food and raw materials for other sectors. The purpose of this study was to determine how big the contribution of different sub-sectors that exist in the agricultural sector, which analyzes sectors influential in changing the economic structure of agriculture in the area and know the potential commodities that can be developed in an effort to enhance the role of the agricultural sector. The research method used through literature study and analysis of secondary data sourced from the relevant authorities. To find out how big the factors that influence changes in economic structures of domination of the agricultural sector into non-agricultural sector estimates used Ordinary Least Square (OLS). For the determination of the potential commodities that can be seeded used method approach Location Quotient (LQ). The results showed the greatest contribution of the different sub-sectors within the agricultural sector contained in the food crops sub-sector. Based on the rate of growth per year, plantation crops sub-sector occupied the highest positions. The sectors that provide real impact on the agricultural sector's contribution to the regional gross domestic product �of the building sector and services sector. Potential commodities that can be developed in different areas in Manokwari regency include food crops and pulses, vegetables and fruits and livestock including cows, goats, pigs and chicken.</em>

<em>The objective of this experiment was to identify the growth and production responses of rice genotypes to drought period. Rice plants were grown under plastic house in plots separated by a massive walls and water was suplied by inlet pipe line. Drought treatments were placed as main-plot, consisted of K3, K6, K9 (water was supplied till 3, 6, and 9 weeks after rice transplanting (WAT), respectively) and control (standard rice growing without drought treatment).� Rice genotypes were placed as sub-plot, consisted of IR-64 and Ciherang (low land type improved varieties), IPB-97 (new plant type), Menthik Wangi (an aromatic local low land rice), Rokan (a hybryd rice), Way Apo Buru (amphibian type), Jatiluhur and Silugonggo (up land type). The results showed that rice growth and yield were significantly affected by drought treatment, especially in K3 and K6. Low yield in K3 and K6 were mostly caused by increased of unfilled spikelet. Jatiluhur, Ciherang and Way Apo Buru still showed relatively high yield under drought stress indicated that those genotypes were relatively tolerant to drought stress; Silugonggo and IPB-97 showed relatively medium tolerant to drought stress; IR-64, Menthik wangi and Rokan showed the most sensitive one.</em>

<em>The severity of Cercospora disease under natural infection was thought related to resistance of tomato varieties. To know the difference of tomato varieties resistance to Cercospora, an artificial infection was conducted in the screen house using a randomized design. Inoculation of Cercospora was given by spraying 10<sup>6</sup> spores ml<sup>-1</sup> to 4 plant thoroughly with hand sprayer, while control plants were inoculated with sterilized water. The severity of diseases was observed on 3 tomato leaves� each 3 days after symptoms was seen first time.� All tomato varieties tested : Amelia, Arthaloka, Ratna, and� Permata was susceptible to the Cercospora infection. The symptom development (r) was varied from 0,32 to 0,61 unit per day. Resistancy of tomato varieties to Cercospora sp. Is discussed.</em>

<em>Sago starch drying done to reduce the moisture content in starch, so as to increase the shelf life and quality of dry starch. The drying process should be done while maintaining the physicochemical properties of sago starch. The research goal is to find the proper drying techniques to produce dried sago starch has a moisture content corresponding to the Indonesian National Standard (SNI). The experiments were performed three times with variations in temperature 40<sup>o</sup>C, 50<sup>o</sup>C, and 60<sup>o</sup>C. The moisture content of sago starch obtained at temperatures 40<sup>o</sup>C, 50<sup>o</sup>C, and 60<sup>o</sup>C, respectively 13.75% wb, 13.50% wb and 13.42% wb. Drying time at drying temperature of 40<sup>o</sup>C, 50<sup>o</sup>C, and 60<sup>o</sup>C respectively 5.5 hours, 4 hours, and 3 hours. A good drying sago starch using cross flow fluidized bed dryer at a temperature of 60�C ie, it reduces the moisture content more quickly in accordance with the SNI, and gelatinization does not occur during the drying process.</em>

<em>This research was carried out to identify species of fungi on soybean seeds at several processing �tahu-tempe� units in the District of Manokwari, in relation to the condition of storage and working places, such as : temperature, humidity, cleanness, period of storing and transportation of seeds. Results show that 8 funguses were found in attacking the seeds and was successfully identified, they are : Aspergillus flavus</em>, <em>A. niger, A. ochraceus, A. aculeatus, A. versicolor, Penicillium chrysogenum, Rhizopus oryzae, </em>and <em>Fusarium oxysporum</em>.<em>. Three� funguses, i.e. Aspergillus, Penicillium and Fusarium produce dangerous toxin (mycotoxin) to human in term of carcinogenic. It was known that soybean seeds was not save as food if were contaminated with fungus. Therefore, factors that caused growth of fungus on soybean seeds in the processing units in Manokwari should be prevented.</em>

<em>Radish (Raphanus sativus L.) is popular in the world as a root vegetable. In Indonesia, the yield of radish is low due to several factors such as the cultivation system. Fertilization and mulching are among the cultivation system which are widely known to improve crop growth and yield. The research aimed to study the effect of bokashi-fertilizer and mulch combination on yield of radish (Raphanus sativus L.). A field experiment was conducted at the Experimental Garden of Agriculture and Agricultural Technology Faculty, The State University of Papua, Manokwari. This experiment was set up in a randomized block design, consisting of three kinds of bokashi namely firewood/ashwood-bokashi (B1), firewood-bokashi (B2), ashwood-bokashi (B3) and four kinds of mulches consist of transparent plastic mulch (M1), black/silver plastic mulch (M2), gliricida mulch (M3) and imperata mulch (M4). The overall treatments were as follows: control, B1M1, B1M2, B1M3, B1M4, B2M1, B2M2, B2M3, B2M4, B3M1, B3M2, B3M3, B3M4. The results show that yield of radish was not affected by application of the bokashi and mulch combination. Even though, no statistically significant, the application of bokashi and mulch increased plant fresh weight by 59%, tuber fresh weight per plant 61.28%, leaf weight 45.79%, tuber length 19.38% and tuber diameter 22.38% compared to control.</em>

<em>The aim of this research was to evaluate the chemical composition of tubers and cassava starch and cassava starch physical Masni District. This study consists of three (3) stages: preparation of materials and chemical characterization of fresh tubers, starch extraction and chemical and physical characterization of cassava. Extraction is done by using a 3:1 ratio of water and tubers. The results showed that the starch content of the fresh tubers ranged from 13.12% to 46.09% while the starch content of cassava starch between 81.40% to 89.55%. Amylose starch levels ranged from 12.28% to 27.38% while the amylopectin content ranged from 72.61% to 87.71%. Starch granule shape is round, round cut, elliptical with a size ranging between 5-25 ?m, the temperature ranges from 65-69<sup>o</sup>C gelatinization and power development starches ranged from 1.42 to 26.65.</em>
