Salah satu kebutuhan masyarakat perkotaan saat ini adalah tersedianya bahan makanan yang praktis, yaitu yang bersifat ready to cook (siap untuk dimasak) dan ready to eat (siap untuk dimakan). Ready of cook artinya hanya membutuhkan sedikit waktu untuk menyiapkan makanan. Salah satu bentuk makanan yang bersifat ready to cook adalah nugget. Penelitian ini bertujuan untuk mengetahui perbandingan berbagai bahan pengikat dan jenis ikan yang berbeda dalam menghasilkan mutu fish nugget dengan mutu fisik, kimia dan mutu organoleptik yang baik. Penelitian ini menggunakan Rancangan Faktorial dengan dasar Rancangan Acak Lengkap (RAL), yang terdiri atas 2 faktor. Faktor pertama adalah jenis bahan pengikat, meliputi: Tepung Terigu; Tepung Tapioka; Tepung Maizena dan Tepung Kentang. Faktor kedua adalah jenis ikan, yaitu: Ikan Tongkol dan Ikan Tenggiri. Setiap perlakuan diulang sebanyak 2 kali. Peubah yang diamati meliputi kadar air, lemak, protein, abu, serat kasar, karbohidrat dan uji kekerasan. Untuk melihat perbandingannya maka dilakukan pengamatan terhadap nugget sebelum dan setelah digoreng. Selain itu, dilakukan pengamatan terhadap uji organoleptik dan uji daya serap minyak. Data pengamatan dianalisis menggunakan uji F kemudian dilanjutkan dengan uji Tukey Honestly Significant Difference (Tukey-HSD) pada taraf 5%. Hasil penelitian menunjukkan penggunaan tepung maizena dan ikan tenggiri disukai oleh panelis (memiliki sifat fisik empuk dan penyerapan minyak rendah) dan sifat kimia (

Hasil analisis kristanilitas difraktogram XRD pati ubi banggai asetat diperoleh pada waktu reaksi 50 menit (16,97%) yang bersifat kristalin.Modification of Starch by Acetylation of the Acetyl Function Group and the Kristanility of Banggai Yam Starch AcetateAbstractThis study aims to determine the characteristics of the acetyl functional groups and the Banggai yam acetate crystallinity by acetylation modification of starch with different reaction times. This study uses a Completely Randomized Design with treatment time of reaction (T) namely T1: 30 minutes, T2: 35 minutes, T3: 40 minutes, T4: 45 minutes, T5: 50 minutes, T6: 55 minutes. This study was conducted to determine the binding characteristics of the acetyl FTIR functional groups and the XRD crystallinity. The results showed that the formation of banggai yam starch with acetate was indicated by the results of FTIR identification in the form of absorption of carbonyl groups (C = O) at wave number 1651.07 cm-1, 1645.28 cm-1, 1643.35 cm-1, 1645, 28 cm-1, 1651.07 cm-1 and 1647.21 cm-1 and the appearance of the functional group (C-O) esters of the acetyl group at wave number 1163.08 cm-1, 1161.15 cm-1, 1159.22 cm-1, 1161.15 cm-1, 1163.08 cm-1 and 1155.36 cm-1. The results of the analysis of the XRD diffractogram crystallinity of starch cassava proud with acetate were obtained at a reaction time of 50 minutes (16.97%) which were crystalline.Keyword : Banggai yam starch, asetylation, FTIR, XRD

<em>This work deals with the effect of banana (sweet plaintain or ‘kepok’ variety) hump flour substituted to wheat flour in the making of noodle, on physical, chemical, and sensory characteristics of noodle.  A completely randomized was employed, with three replicates. Sensory analysis was conducted according to randomized group design. Four proportions of banana hump to wheat flour (10:90, 20:80, 30:70, and 40:60, weight basis) was studied. Results showed that the best physical and chemical characteristics was shown by noodle made from 10:90 proportion of banana hump to wheat flour, with 4.59% water absorption, 0.57% cooking loss, 10.37% water content, 34.21% starch content. However, result of sensory analysis suggested that the most liked noodle was that made from flour proportion of 20:80 with ‘like’ for colour, ‘like very much’ for aroma, ‘like’ for texture, ‘like’ for taste, and ‘like’ for overall preference</em>

The purpose of this research is to know and study various combination of carrot flour to chemical quality and organoleptic quality of tuna nugget. This study used Completely Randomized Design (RAL) with 4 treatments, and 4 replications. The research that will be done is as follows: R0 = 15% tapioca starch + 5% cornstarch + 0% carrot flour; R1 = 10% tapioca starch + 5% maize starch + 5% carrot flour; R2 = 5% tapioca starch + 5% maize flour + 10% carrot flour and R3 = 5% tapioca starch + 15% carrot starch. Each treatment was repeated four times, so there were 16 experimental units. To know the effect of the experiment, then the diversity test is done and if the result of the diversity test show the real effect, then continued with the test of the Least Significant Difference (LSD). The results showed that the addition of various carrot starch combinations had significant effect on protein content, crude fiber and tuna nugget fat but no significant effect on water content, b-carotene and organoleptic qualities of tuna nugget. a 10% tapioca starch combination, 5% cornstarch and 5% carrot flour give the highest levels of protein, coarse fiber, tuna nugget fat. Combination of 5% tapioca starch and 15% carrot flour gave the organoleptic qualities of tuna nuggets tend to be favored by panelists.

This study aims to determine and analyze the factors that affect the yield of gogo rice plants in Morowali District, Central Sulawesi Province. This research was conducted in Morowali District, Central Sulawesi Province. The method used in sampling in this study is simple randomly selected. In this simple random technique each member of the population has the same opportunity to become a sample. This study analyzes the function of results using multiple linear regression analysis. Variable identification is done by listing production factors that are thought to have an effect on the process of upland rice yields. On the factors of production the variables that are affected (dependent variable) are results. While the variables that are variable (independent) affect are the area of ​​land, seeds, fertilizers, pesticides and labor. The results showed that the factors of production of land area, seeds, labor, fertilizers, and pesticides jointly influence the yield of upland rice. Variable land area partially has a significant effect on upland rice yields, with the highest average yield obtained in land area of ​​≤ 0.50 ha (average 3.76 t / ha). Partial variables of seed, labor, fertilizer, and pesticide did not significantly influence the upland rice yield respectively.
