Tepung terigu digunakan sebagai bahan baku dalam pembuatan roti.Indonesia hingga saat ini masih mengimpor terigu dalam jumlah besar. Substitusi tepungterigu dengan produk labu kuning sangat mungkin dilakukan karena kaya karbohidrat.Penelitian ini bertujuan untuk mengetahui karakteristik fisikokimia roti tawar yangdisubstitusi sebagian dengan pasta beku labu kuning. Penelitian ini menggunakanRancangan Acak Kelompok (RAK) pola faktorial yang terdiri atas 2 faktor, yaitupersentase substitusi sebagian tepung terigu dengan pasta labu kuning (R1 = 10%, R2 =20%, R3 = 30%, dan R4 = 40%) dan konsentrasi bahan pengemulsi yang digunakan(S1 = 0,5% dan S2 = 1%). Parameter yang diamati meliputi kadar air, kadar abu dankadar betakaroten untuk bahan baku labu kuning, dan analisis kadar abu, kadar air, kadarbetakaroten, rasio pengembangan adonan roti dan volume spesifik untuk roti tawar. Hasilpenelitian menunjukkan bahwa faktor persentase substitusi pasta labu kuning memberikanpengaruh sangat nyata (Pâ¤0,01) terhadap kadar abu dan kadar betakaroten danberpengaruh tidak nyata (P>0,05) terhadap kadar air, volume spesifik dan rasiopengembangan adonan roti tawar. Faktor konsentrasi bahan pengemulsi memberikanpengaruh nyata (Pâ¤0,05) terhadap rasio pengembangan adonan roti tawar danberpengaruh tidak nyata (P>0,05) terhadap kadar air, kadar abu, kadar betakaroten danvolume spesifik roti tawar setelah pemanggangan. Tidak terdapat interaksi keduanya(P>0,05) terhadap semua parameter yang diuji. Semakin tinggi persentase substitusi pastalabu kuning yang digunakan, maka kadar betakaroten pada roti tawar semakin meningkat.Kadar betakaroten tertinggi terdapat pada persentase substitusi pasta labu kuning 40 %.Rasio pengembangan adonan yang lebih tinggi didapatkan pada konsentrasi bahanpengemulsi 1%.

ABSTRACTChanges in lifestyle cause people to demand the availability of functional foods that are ready to eat, nutritious and positive for health as a part of the daily menu. A food ingredient can be said to be functional if it contains components (both nutritional and non-nutritional) which have beneficial physiological effects on the functions of organs in the body. The biological role of resistant starch as an ingredient of functional food is related to the ecology of "good" microbes that live in the large intestine (colon). The use of rice flour as a source of resistant starch is an innovation to utilize broken rice, which can be applied by industries with a wide range of businesses. Modification of rice flour to increase levels of resistant starch can be done physically, chemically, enzymatically or in combination. Each of these production processes will affect the characteristics of the hospital produced. Based on the production process, characteristics, functional values, and alternative uses, rice flour rich in resistant starch has considerable potential to be developed as a functional food product for health.

Konsumsi talas dengan asam oksalat yang tinggi dapat merusak atau membahayakan kesehatan khususnya pada ginjal, yaitu akan terbentuknya batu ginjal. Talas di beberapa daerah dijadikan salah satu pengganti bahan pokok, bahkan talas terkenal dengan makanan yang rendah akan kandungan gulanya. Tujuan dari penelitian ini adalah memanfaatkan umbi talas sebagai bahan diversifikasi terutama pada makanan yang rendah kandungan gula sehingga dapat digunakan bagi penderita diabetes. Pada penelitian ini dilakukan metode kombinasi fisik (perebusan dan pengukusan selama 20 menit) dan kimia (natrium bikarbonat 6%, asam asetat 20%, dan natrium klorida 10%) untuk menurunkan kadar oksalat pada varietas talas yaitu talas kimpul (Colocasia esculenta) dan talas ungu (Xanthosoma sagittifolium). Kadar oksalat talas kimpul terendah diperoleh dari perlakuan fisik perebusan dilanjutkan dengan perendaman asam asetat 20% yaitu sebanyak 16,889 mg/100 g talas dari kadar awal yaitu 42,35 mg/ 100 g talas. Sedangkan pada talas ungu, kadar oksalat terendah diperoleh dari perlakuan fisik perebusan dilanjutkan dengan perendaman natrium klorida 10% yaitu sebanyak 18,237 mg/100 g talas dari kadar awal 73,06 mg/ 100 g talas, sehingga dapat memenuhi ambang batas 71 mg/100gr berdasarkan hasil penelitian sebelumnya.

The purpose of this research is to analyze the consistency of daily CPO quality at the palm factory PT. XYZ for the last 3 months, that is January, February and March 2021. Based on three quality parameters, that is free fatty acids (FFA), water content and dirt content. The data is evaluated by the I-MR chart method and then compared with the quality specifications of the company and the buyer. Meanwhile, critical points and critical conditions that most influence the quality of palm oil were identified using the FMEA method. The results showed that FFA and water content of CPO were still not statistically controlled, which was indicated by the presence of data points that were outside the control limits. The parameter of FFA CPO quality in January 2021 is the highest with an average of 3.91%. The highest water content quality parameter is in March 2021 with an average 0.398%. And the highest dirt quality parameter was in February 2021 with an average 0.039%. The cause of the variation in the quality CPO was identified from 5 critical conditions where the highest RPN value is the use of restant fresh fruit bunch in the palm oil processing process. The proposed improvement that can be given to palm factory PT.XYZ is to implement a fast processing system using the FIFO (First In First Out) system so that the raw materials that is fresh fruit bunch are not too long and pile up at the loading ramp.

Standardization of Working Time at Cocoa Processing Unit, Rimbun Cooperative, Pidie JayaABSTRACT. Rimbun Cooperative is a business unit operating a chocolate factory producing several chocolate products such as cocoa fat, cocoa powder, 3 in 1 instant drinks (sachets), and chocolate bars. This research aims to measure standard times of operators in all working stations of the chocolate factory. These standards comprised the standards in roasting, peeling, pasting, pressing, powdering, powder sieving, powder mixing, dough mixing, refining, and chonching working stations. The data were directly collected using Time Study method with Stop Watch. The samples were randomly selected with five (5) repetitions; and the standard times were measured using Westinghouse Method to quantify performance and allowance factors. The result shows that standard times of operators in each working station are as follows: roasting (36 minutes), peeling (193 minutes), pasting (276 minutes), pressing (78 minutes), powdering (17 minutes), powder sieving (14 minutes), powder mixing (36 minutes), dough mixing (17 minutes), refining (30 minutes), and chonching (30 minutes). In peeling, pasting, powdering, powder sieving working stations, standard times of operators cannot be separated with working times of machines because the operators are required to run the machines (sequence). In general, standard times of operators, after calculation, are larger than direct records because during the working times, operators would not or could not use allowance factors for personal uses, such as for going to bathroom, drinking, and socializing with their colleagues as means to reduce stress or boredom.
