Abstract

Rembiga satay is an indigenous processed beef product from West Nusa Tenggara. It undergoes marination with distinctive spices before grilling, contributing to its unique flavor profile. The product's specialty lies in its sensory attributes, distinctly reflecting the characteristic traits of the Lombok region, making it irreplaceable by comparable products from other regions. This study's objective was to thoroughly examine the sensory profile attributes of Rembiga satay using Quantitative Descriptive Analysis. Two methods, namely Rate All That Apply and Flash Profile, were employed for this evaluation. The research involved the engagement of 100 consumer panelists assigned to evaluate the sensory characteristics of four different Rembiga satay products, considering aspects such as taste, aroma, flavor, and texture. Results from the Flash Profile and Rate All That Apply methods consistently indicated that panelists discerned analogous sensory attributes in Rembiga satay. Specifically, Rembiga satay Ririn showed a sensory profile characterized by grilled meat flavor, Rembiga satay Lomboku featured grilled meat flavor, grilled meat aroma, and smoky aroma, and Rembiga satay Napisah presented attributes such as fibrous texture, sweetness, juiciness, spicy aroma, and meat flavor. Meanwhile, Rembiga satay Sinasih exhibited a sensory profile inclusive of umami, chili spiciness, black pepper spiciness, smoky flavor, grilled meat aroma, and chewiness

Abstract

The main challenges in producing gluten-free bread are closely related to its development, texture, and nutrition. This research consisted of 2 stages.  Stage 1 was aimed to determine the effect of voltage variations (70 V, 80 V, 90 V, 100 V, 110 V, 120 V, and conventional baking as a control) on bread characteristics and process parameters. The experiment was arranged as non-factorial in a completely randomized design with 3 replications. The best results of the first stage were applied in stage 2, aimed to determine the effect of various concentrations of TGase (0, 0.5, 1, 1.5, 2, and 2.5%). The data were processed using analysis of variance, then further tested using Tukey's at the 5% level. The 120 V voltage gradient treatment was found to be the best treatment. It shows specific volume 3.17±0.17 cm3/g, baking loss 14.58±1.50%, brightness 50.97±3.27, hardness 3.76±0.11, cohesive 0.34±0.03, pore density 84±2.52. In addition, baking at a higher voltage level increased the temperature rate and electrical conductivity. The 120 V voltage treatment shows the time required to reach a maximum temperature of 97°C was 3 minutes 5 seconds, and an electrical conductivity value of 0.26-0.51 S/m. Based on the TGase treatment, it was found that when bread dough was applied with a higher TGase concentration, the specific volume, hardness, chewiness, resilience, cohesiveness and springiness, average pore size, and pore porosity of the bread increased.

Abstract

Shortening is a solid fat with the functional properties needed to produce a better texture and appearance for bakery or confectionery products, as well as frying and cooking media. Shortening is made by mixing two or more vegetable oils and then modifying them through a chemical or enzymatic interesterification process. In this research, the raw material for shortening was prepared from a mixture of 2 types of palm oil olein: refined olein (ROL) and mid olein (MOL). This research aimed to determine the optimal ROL and MOL mixture ratio in the chemical interesterification process, which produces shortening with the best quality and specifications. Five levels of ROL/MOL comparison consisting of (100/0), (95/5), (90/10), (85/15), and (80/20) were chemically inter-esterified using a sodium methoxide catalyst under a vacuum of 0.8 bar at a temperature of 110 oC and speed of 500 rpm. The results showed that the increase of MOL in the ROL/MOL formulation tends to increase the shortening melting point. However, increasing MOL did not change the iodine value, and all the ROL/MOL ratios produced shortening with specifications that met the SNI 3718:2018 requirement, and the best ROL/MOL ratio was 80/20.

Abstract

Waxy corn is a commodity that can be developed into various food products; one is instant porridge, which only requires a short cooking preparation process because it has undergone previous processing. This research aimed to determine the physicochemical and sensory properties of instant porridge made from nixtamalized waxy corn. This research used a completely randomized factorial design (CRFD). The first factor was soaking time (30, 60, and 90 minutes), and the second was pregelatinization time (5, 10, and 15 minutes). The results showed that soaking and pregelatinization time significantly affected rehydration capacity, rehydration time, and viscosity. In contrast, the effect on syneresis and sensory properties was only affected by one of the factors. Instant nixtamalized corn porridge with a soaking time of 90 minutes and a pregelatinization time of 15 minutes was the best instant nixtamalized corn porridge with highest rehydration capacity (5.78 ml/g), calcium content (66.80 mg/L), and viscosity (3850 cP), smallest syneresis value (29.94%), and shortest rehydration time (2.19 minutes), with a neutral taste preference, while the panelists somewhat preferred color, texture, and aroma.

Abstract

Gayo Arabica coffee has three cultivars that farmers in the Gayo Highlands commercially manage: Timtim, Borbor, and Ateng Super. Coffee blending is necessary to optimize the quality of Gayo Arabica coffee brews. In addition to the blend formulation, the brewing method also affects the quality of the brew. This study aims to understand the quality of coffee brews and consumer acceptance of two blending formulations optimized from previous research, brewed using four different brewing methods. The research used a factorial randomized block design with two factors. The first factors were the Gayo coffee blend formulation, 25% Timtim + 50% Borbor + 25% Ateng Super and 50% Borbor + 50% Ateng Super. The second factor was the coffee brewing method consisting of 4 levels: manual brew, French press, V60, and espresso. Brew quality parameters included pH, total dissolved solids, antioxidant activity, and sensory attributes such as aroma, flavor, body, aftertaste, and overall. The results showed that the interaction between the coffee blend formulation and the brewing method did not significantly affect the flavor in the sensory test. The coffee blend formulation significantly affected aroma, aftertaste, body, and overall but did not significantly affect antioxidant activity (65.87-65.42%), total dissolved solids (1.35°Brix), and pH. The Simple Additive Weighing method ranking test indicated that the best treatment combination was found in the formulation of 25% Timtim + 50% Borbor + 25% Ateng Super brewed using the French press method.

Abstract

Cascara is a beverage derived from dried coffee cherry pulp, known to have good functional value but with a short shelf life. Fermentation is a technique that can enhance cascara beverages' shelf life and quality and their functional value due to the presence of probiotics and increased antioxidant compounds. The study aimed to optimize the fermentation conditions of cascara tea with water kefir seeds to improve the microbiota content of Lactobacillus sp, Bifidobacterium sp, and Saccharomyces cerevisiae and the antioxidant activity of the beverage. The method in this study used Response Surface Methodology (RSM) with a design selection of Central Composite Design (CCD), using two independent variables, namely fermentation time (X1) and Grain Concentration (X2), with a response of antioxidant activity (%). The findings indicated that a fermentation period of 48 hours and a grain concentration of 8.58% resulted in a probiotic drink exhibiting the maximum antioxidant activity of 65.53%. This optimum treatment resulted in a drink with IC50 antioxidant activity of 173.66 ppm, total phenol 477.24 mg GAE/mL, brightness value (L*) 30.69, redness (a*) 14.06, yellowness (b*) 29.57, pH 3.57, TPT 8.80 (ᵒBrix), viscosity 1.62 mPa.s, total LAB 8.54 log CFU/ml, and total yeast & mold 10.93  log CFU/ml.

Abstract

Protein is one of the macronutrients that the body needs in large quantities in addition to carbohydrates and fats. Eating high-protein biscuits can be one way to meet daily protein needs. Biscuits made from sorghum flour, peanuts, and Moringa leaves can produce non-gluten biscuits high in protein. This study aimed to determine the optimal balance of using sorghum flour, peanuts, and moringa leaves to produce high-protein biscuits with acceptable sensory values. The research method used is an experimental method with descriptive data analysis. The optimization method uses the Response Surface Methodology (RSM) experimental design with a central composite design (CCD). The best biscuit formula, as a result of the RSM experimental design optimization, has a protein nutrient content of 8.71%, 2.60% moisture content, 2.60% ash content, 32.99% fat content, and 53.85% carbohydrate content. The combination of using flour significantly affects the texture of the biscuits but does not significantly affect the color. Using composite flour consisting of 60% sorghum flour, 37% peanuts, and 4% moringa leaves to manufacture non-gluten biscuits can produce biscuits that are high in protein and have physicochemical properties and good sensory acceptability.

Abstract

Green tea production activities at PT Candi Loka indicated a time-consuming, which caused process efficiency to be less than optimal. Process efficiency improvements must be made to increase company competitiveness and consumer satisfaction. This research aimed to analyze the efficiency of green tea production time at PT Candi Loka by identifying the processing time required in each production activity, including the time consumption and formulating recommendations for improvement using a lean manufacturing approach using the VSM (Value Stream Mapping) method. There were 30 activities in 6 processes consisting of receiving raw materials, withering, rolling, drying, and packaging. Identification of value streams using the PAM (Process Activity Mapping) tool produced 9 Value added (VA) activities, 19 Necessary but Non-Value Added (NNVA) activities, and 2 Non-Value Added (NVA) activities in the form of delays in the withering and drying processes. In the current state map analysis, the production lead time value was 315.286 seconds. Recommended improvements to eliminate delays in the withering process were to set up the rotary panner machine earlier and increase the number of supervisors, while to eliminate delays in the drying process were to implement a piece rate system. Increasing efficiency was also carried out by improving NNVA activities by adding weighbridge facilities and using a conveyor system. The future state map proposed by implementing recommended improvements resulted in an increase in production time efficiency to 222.356 seconds and an increase in the process cycle efficiency value from 58.95% to 84.85%.

Abstract

Palm oil plants, after reaching the end of their productive life, need to be rejuvenated with proper handling to prevent old palm trunks, which have been cut down, from being infested by beetles and the growth of Ganoderma sp. fungus, which can damage productive palm oil plants in the vicinity. The old oil palm trunks contain sap and have been utilized. The residue of the oil palm trunk after sap extraction contains carbon compounds that can be used as raw material for bio-pellets, representing an added value potential.  In this study, the composition of sap-free palm trunk dregs as raw material for bio pellets and the manufacture of bio pellets using sap-free palm dregs with a combination of particle size treatment and pressing pressure of T1M1 (0.4882 kg/cm2; 10 mesh); T1M2 (0.4882 kg/cm2; 20 mesh); T1M3 (0.4882 kg/cm2; 40 mesh); T2M1 (0.9764 kg/cm2; 10 mesh); T2M2 (0.9764 kg/cm2; 20 mesh); T2M3 (0.9764 kg/cm2; 40 mesh); T3M1 (1.4647 kg/cm2; 10 mesh); T3M2 (1.4647 kg/cm2; 20 mesh); and T3M3 (1.4647 kg/cm2; 40 mesh) using a hydraulic shop press to produce bio-pellets with a length of 2.5 cm and a diameter of 1.2 cm. The research used a descriptive method by presenting data as diagrams and tables. The results showed that the nira-free palm dregs used as raw material for the best bio-pellets in the T2M1 treatment (0.9764 kg/cm2; 10 mesh) contained 25.7% hemicellulose, 47.6% cellulose, and 7.2% lignin. The pellets produced contained 6.50% moisture content, 5.01% ash content, and 4416.93 cal/g heating value.

Abstract

Chocolate is a processed product derived from cocoa beans that has undergone fermentation, drying, roasting, and grinding to produce high-quality cocoa powder. The processing of chocolate in a company involves many lengthy stages. Implementing a marketing mix is used as a technique to increase sales. The company needs to identify the superior products favored by consumers to develop priority marketing strategies. This study aims to analyze the application of the marketing mix in the chocolate industry and generate prioritized marketing strategies for the superior chocolate products produced by a company in Bali. The research method used is the Analytical Hierarchy Process (AHP). The results indicate that the marketing mix includes chocolate products such as chocolate cream, chocolate bars, and liquid chocolate. Product pricing depends on the form, with the most apparent pricing being for chocolate bars, calculated based on weight in grams. The production site is located at the main factory, which processes cocoa into chocolate cream, chocolate bars, and liquid chocolate, allowing consumers to experience the chocolate processing firsthand and try packaging chocolate at the factory. Chocolate promotion is continuously carried out through offline and online media, such as the company's website, which provides background information on chocolate production to the industry in Bali. The priority in chocolate marketing, based on the Analytical Hierarchy Process, is chocolate cream, followed by chocolate bars and liquid chocolate.
