Abstract

Abstract. The problem for small businesses of mocaf-based products is drying. Thus, a dryer is needed which will be attempted through an apprenticeship program. Another problem is the need to expand the type of business. Through the diversification of cassava products, it produces mocaf noodles which can be sold at higher prices, thereby increasing income and improving people's welfare. The aim of PkM is to increase and maintain production continuity, as well as increase profits through the creation of derivative products. The target audience is people who are already engaged in the mocaf flour business and small culinary entrepreneurs. The training method is in the form of tutorials and technical training by integrating Islamic values into it. Based on the results of the apprenticeship, small ovens can be made by themselves. However, the production of large ovens cannot be completed considering there is still a shortage of funds. The manufacture and marketing of noodles have been occupied by several small culinary entrepreneurs and sold to meatball traders, as well as sold to consumers who have been customers before. The conclusion is that in order to increase mocaf flour production, it is necessary to make a good drying oven. The PkM team was able to build only 75% of the drying ovens, so more assistance and funding was needed. From the perspective of increasing mocaf-derived products, mocaf noodles are a profitable option, and giving rise to many new entrepreneurs.

Abstract

PKM is aimed at cassava farmers and the village community of Rende. The role of farmers and businesses processed foodis very much needed considering the economic condition has decreased since the Covid-19, meanwhile government changed the direction of development by prioritizing economic. Farmers complain that it is difficult to sell until difficult to improve their welfare. The purpose of PKM so that the harvest can be sold in product, in the form of mocaf flour with the intention that it is not difficult to sell and the price is higher. The target audience is those who need and are willing to be fostered in the business, goal ultimateis the establishment of sustainable business. The method of activity is tutorials and training. Based on the results of PKM assistance, there are 7 participants who are serious about doing business through partnerships and marketed, so that the harvest is utilized and sold because Mocaf can last 1 year. The price of cassava hasn’t increased because it’s still from their own plantations and the amount of production is limited. Marketing has been done online, but has not been able to meet demand due to production constraints PKM ini ditujukan pada petani singkong dan masyarakat desa RendeBandung Barat. Peran petani dan pelaku usaha makanan olahan sangat dibutuhkan mengingat kondisi perekonomian desa Rende – mengalami penurunan semenjak mewabahnya Covid-19, sementara itu pemerintah daerah mengubah arah pembangunan dengan memprioritaskan recovery perekonomian. Petani mengeluhkan sulitnya menjual hasil panen, tengkulak hanya membeli sebagian dengan harga rendah sehingga sisa panen tidak termanfaatkan, kemudian dibuat gaplek sebagai pakan ternak berharga murah. Akibatnya petani sulit meningkatkan kesejahteraannya. Tujuan PKM ini agar hasil panen dapat dijual dalam bentuk olahan, berupa tepung mocaf dengan maksud agar tidak sulit dijual dan harganya lebih tinggi. Khalayak sasaran adalah yang membutuhkan dan bersedia dibina dalam bisnis mocaf, tujuan akhirnya adalah terbentuknya usaha mocaf bekesinambungan. Metode kegiatannya tutorial dan pelatihan, tutorial pemasaran dan menyisipkan kewirausahaan islami. Berdasarkan hasil pendampingan PKM menunjukkan bahwa terdapat 7 peserta yang serius melakukan bisnis melalui kemitraan dan dipasarkan secara online, sehingga hasil panen termanfaatkan dan terjual karena mocaf dapat bertahan 1 tahun. Harga singkong belum meningkat karena masih dari kebun milik sendiri dan jumlah produksi terbatas. Pemasaran sudah dilakukan secara online, namun belum mampu memenuhi permintaan karena terkendala produksi

Abstract

Betle leaf (Piper betle L.) essential oil and catechu nut (Areca catechu L.) extracts have been known to be able to inhibit biofilm formation of S. mutans. This research aimed to characterize the chemical compounds of betle leaf esssential oil, screen the phytochemicals in catechu nut ethanol extract, and assess the inhibitory potential of betle and catechu in chewy candy on biofilm formation by S. mutans. The experiment included preparation of extracts and chemical characterization of the raw materials, formulation of chewy candy, measurement of biofilm inhibition, and sensory evaluation of the candy. In vitro examination for inhibitory potency of betle and catechu chewy candy against biofilm formation S. mutans ATCC 31987 was performed in adhesion phase (4 hours) and active accumulation phase (18 hours). Antibacterial assay was performed in BHI broth media on microplate 96 wells. Crystal violet 0.5% was used to stain the biofilm and Optical Density (OD) was measured at λ 450 nm. The GC-MS analysis detected 32 compounds in the essential oil of betle leaf. The Betle leaf essential oil contained chavicol acetate, isoeugenol, chavibetol acetate, chavicol, and allylcatechol 3.4-diacetate, while catechu nut ethanol extract contained flavonoids and tannins. The components were possibly the inhibitory agents of S. mutans biofilm formation. Chewy candy containing 0.8% betle leaf essential oil and 2.3% catechu nut extract had effective inhibitory potential for S. mutans biofilm formation. Inhibition during adhesion phase was 74.5±0.7%, while that for accumulation phase was 60.8±1.8%. Sensory analysis suggests that the candy was slightly liked by the panelists (5±2).

Abstract

Umami is one of the basic taste produced by monosodium glutamate (MSG). Generally, commercial MSG products did not specify the amount of a certain dose to produce palatable food. This problem could lead to uncontrolled and excessive use of MSG by consumers. The aim of this study was to determine the values for the detection and preference threshold of umami taste from commercial MSG products at different salt level. The detection threshold was determined using R-index method in salt solutions. The preference threshold was determined by using hedonic rating in food model. A food model selected in this case is spinach soup that is commonly consumed by Indonesian. The salt concentrations for detection and preference threshold experiment were 0.42 and 0.30 g/100 mL. Umami taste preference threshold value using Fechner’s psychophysic equation for 0.30 g/100 mL salt concentration is 0.25 g MSG/100 mL, while for 0.42 g/100 mL salt concentration, the umami taste preference threshold value is 0.06 g MSG/100 mL. Detection threshold value using R-index method for 0.30 g/100 mL salt concentration is 0.05 g MSG/100 mL, while for 0.42 g/100 mL salt concentration is 0.02 g MSG/100 mL. Different salt concentrations leads to differences in the values of threshold preferences and detection threshold of the umami taste of MSG. Increasing salt concentration tends to decrease the detection and preference threshold of umami taste from MSG. This research results could be used as the basic information in food product formulation such as seasoning and condiment using mixtures of salt and MSG.

Abstract

The idea of water interaction with chemicals in the food dry matter or solid was inspired from gas interaction with surface active chemicals, almost a hundred years ago, such as association of gases with active carbon. However, until now the mechanisms and consequences of water molecule associated with chemicals in food solid is still in debate among the food scientists. The concept of water interaction or association with chemicals in the food solid or dry matter was initially introduced as water activity (aw), then in the terminology of “Bound Water”. Water activity concept was further developed by Labuza in 1960s. The concept or idea of glass transition temperature (Tg) from Polymers Science discipline was applied to foods in decade of 1980 by Slade & Levine, who denied or negated the earlier concepts of bound water and water activity. In glass transition concept of food products, water functions as a plasticizer related to the textural properties and safety of the products. Knowledge of structure and behaviours of water molecule is required to understand how water interacts or associates with chemicals in food solid. The unique nature of water molecule is a tetrahedral structure with 4 polar angles, which behaves strongly binding or being bound by polar or ionic chemicals in food solid. A number of physicochemical forces act how water molecules interact in complex ways with chemicals in food solid, and the interaction among water molecules in foods. Both types of water interaction lead to the consept of three fractions of bound water as well as to the varities of food characteristics, including preservability and food qualities, either appraisable or unacceptable by consummers. Relationship analyses among various parameter data of associated water in foods such as aw, Me, Tg, and enriched by NMR data, specific weight and specific heat of bound water, indicated that among the different concepts of water interaction in foods were complementary each other and also supported the presence of the three fractions of bound water.

Abstract

Moisture sorption isotherm of food powder products is pertinent in processing and stability of food. Food model consisted of tapioca starch, casein, palm oil and sucrose. The moisture sorption isotherm curves of the food model, tapioca starch and casein were sigmoid indicating the typical shape of amorphous product, while the water sorption isotherm of sucrose was a broken-line curve showing typical shape of crystalline material. The Guggenheim – Anderson-de Boer (GAB) model was the best model to predict sigmoid sorption isotherm curve (tapioca starch, casein and food model) at the whole range of experimental aw (0.07 – 0.97) while the Braunauer Emnet Teller (BET) model only fitted for aw up to 0.6. The Water binding capacity of tapioca at monolayer (Mm) was higher than casein and food model but the coefficient of adsorption energy (C) was lower than that of casein. Addition of oil at the food model decreased the water binding capacity at monolayer. The Grover model was more suitable than Ross model to predict the water sorption isotherm curve of food model from its composition.

Abstract

This research was aimer/ to study the extend of non enzymatic browning reaction in food models containing the mixture of tapioca starch, casein, sucrose and oh at different moisture contents (2.55%, 5.26%, 7.54%, 15.20%. 15.93% and 23.99%) and storage temperatures (30, 55 and 700C). The non-enzymatic browning reaction was detected from brown color intensity measured by spechtrophotometer and colorimetric methods. The non-enzymatic browning reaction or food model follow pseudo-zero order reaction, suggesting that browning reaction occurred at moisture content above monolayer zone. T-Tg (T storage - Tg prediction) and reaction rate constant (k) plots showed that browning reaction occurred at temperature around glass transition and increased significantly at 150 above Tg of casein. Tapioca starch in the food model was under glassy condition. The mobility of substrate increased and diffused at amorphous matrix.

Abstract

This research was conducted to analyze the mindset of small-scale garment business actors from the perspectives of production and marketing, considering that these two aspects have an important role in creating added value in the value chain of small-scale garment businesses. This research uses a qualitative descriptive method. The type of data required is primary data obtained from in-depth interviews with actors from garment businesses located in Bandung City and Bandung Regency. The research results find that the mindset of small-scale garment entrepreneurs from a production perspective shows that most of them are oriented toward always looking for the best production methods and never feeling satisfied (creativity is not a methodology but a mindset). Given that the market for garment products wants to have a relatively fast product life cycle, the emergence of market responses to the products offered is an important input for garment businesses to produce market-oriented products. In relation to the production mindset, garment businesses pay attention to the marketing mindset, where customer loyalty is considered crucial since customers are valued as an asset that supports the business instead of a burden, and marketing is considered a margin center, not a cost center.

Abstract

Propolis has the potential to be widely used in the food industry due to its biological activities that are beneficial for human health, including as an antioxidant. The objectives of this research were to produce encapsulated propolis extract powders (EPEP) in optimum formula using a combination of coating materials (maltodextrin and basil seed gum (BSG)) by spray drying technique, and determining the physicochemical characteristics of the optimum EPEP. The independent variables used for optimization were 1–10 g of liquid propolis extract (factor 1) and 0–0.5 g of dried crude BSG (factor 2). Maltodextrin (10 g) and aquades (100 ml) were set as fixed variables. The optimization used response surface methodology (RSM). The responses studied were moisture content, solubility, and total phenolic content (TPC). Based on the overall response, the optimum formula resulting from RSM was 10 g of liquid propolis extract and 0.5 g of dried crude BSG with a desirability value of 0.734. The optimum EPEP had a moisture content of 3.82%, solubility of 96.13%, and TPC of 901.84 mg gallic acid equivalent (GAE)/kg sample, water activity value of 0.41, hygroscopicity value of 16.82%, and fat content of 4.61%. The results of the antioxidant activity of the optimum product by 2.2-diphenyl-1-picrylhydrazyl (DPPH) assay had an inhibition percentage of 17.61% at a concentration of 5000 µg/ml and antioxidant capacity of 2091 mg ascorbic acid equivalent (AAE)/kg sample. The antioxidant activity of the optimum product by ferric reducing antioxidant power (FRAP) assay gave an antioxidant capacity of 2394 µmol AAE/kg sample. The optimum EPEP morphologically showed agglomerated particles.

Abstract

Jack bean is one of the alternative protein sources, with a protein content of 27.4% on a dry basis. The production of jack beans in Indonesia reached 12 tons/ha, with an average of 7 tons/ha. The utilization of jack bean for food was not optimal because it contained cyanide acid (HCN). For optimal utilization, jack bean must be transformed into low-HCN jack bean flour. HCN levels could be reduced to safe limits through food processing, namely by soaking and thermal treatment. The purpose of this research was to study the effect of jack bean pretreatment (no soaking, water soaking, or NaHCO3 soaking) followed by heat treatment (boiling or roasting) on HCN levels, proximate content, and physical characteristics of jack bean flour. Peeled jack bean is given a soaking treatment (without soaking, soaked in water for 24 hours, and soaked for 24 hours in NaHCO3 1%), followed by boiling for 60 minutes or roasting for 30 minutes, then dried and ground. The jack bean flours is analyzed for HCN content, water content, ash content, fat content, protein content, and carbohydrate content, as well as the degree of whiteness and aw.. This study showed that soaking treatment for 24 hours followed by boiling for 1 hour could reduce HCN levels to 4 mg/Kg, but roasting treatment could increase HCN levels in jack bean flour compared to the control. Pretreatment had a significant effect on water content, ash content, and fat content, while protein and carbohydrate levels had no significant effect. There was no difference in the degree of whiteness except for the roasting treatment, while the water activity decreased significantly in the range of 0.2-0.5 and lower than without treatment

Abstract

The small-scale garment industry has gained significant influence in Indonesia. However, with the challenges posed by the pandemic era, the industry must adapt to ensure its long-term sustainability. The objective of this research is to analyze the marketing strategy of small-scale garment products, specifically examining the proportion of online and offline marketing strategies, as the success of these products in the market relies on the effective utilization of both strategies. The urgency of this research stems from the daily market demand for garment products and the crucial role played by dominating small-scale garment companies in contributing to the economy's development. This research adopts a mixed-method approach, incorporating both qualitative and quantitative methods. The qualitative approach involves conducting interviews with owners of small-scale garment businesses, commonly known as convection businesses. Meanwhile, the quantitative approach is used to analyze the proportion of online and offline marketing strategies. The qualitative analysis utilizes a Markov approach to provide insights into future marketing strategy proportions and possibilities. The research was conducted at a small-scale garment center located in Kutawaringin Village, West Bandung Regency. The results indicate that during the pandemic era, garment businesses have increasingly embraced online marketing strategies to enhance their marketing performance. Furthermore, businesses that have traditionally relied on offline marketing are also increasing their proportion of online marketing strategy implementation. [ABSTRACT FROM AUTHOR]

Abstract

The problem of small entrepreneurs lies in the drying of cassava chips. Incomplete drying causes the color to become black, the taste and aroma to be less than perfect. The drying technique used was sunlight, because during the rainy season the production cannot be continued with limited stock and increased number of orders, while stock is limited and orders increase. This program is directed to an apprenticeship with the aim to make oven in the future. Another problem is the need to expand. Therefore, training on making mocaf noodles was held because the market for noodles was high. The market will be wider through product/derivative diversification, which has implications for increasing people's income and welfare. Another activity is involving participants in online marketing training. The purpose of PKM is to increase and maintain production continuity and increase profits through the creation of derivative products. The target audience were people who are already engaged in the mocaf business, small culinary entrepreneurs. The training methods involved tutorials and technical training based on Islamic values. Based on the results of the apprenticeship, small equipment can be easily made; however, the larger ones were not completed due to the shortage of funds. The manufacturing and marketing of noodles have been occupied by a number of small culinary entrepreneurs, and sold to meatball traders and consumers who were customers initially.

Abstract

A small leakage in the primary circuit of a nuclear power plant reactor may trigger the occurrence of countercurrent flow which probably develops into a flooding regime followed by the zero penetration caused core cooling failure. During extensive studies in the flooding phenomena in the PWR hot leg, the geometry effects have been widely investigated. The present study investigates the effects of I/D ratios of the riser on the interfacial fluctuations during the counter-current flow on a 1/30 scaled down PWR hot leg geometry. Here, the liquid film fluctuations were acquired by using parallel wire array probes on the basis of a conductance concept. Three I/D ratios which were varied consisted 1.9 (R1), 3.9 (R2) and 8.3 (R3). The obtained data were analyzed on the basis of both time and frequency domains. From the PDF the flooding regime obtains multimodal distributions, while the PSD approaches lower frequencies with higher magnitudes corresponding to either the occurrence of water blockage or slugs. Keywords: I/D ratio, water level fluctuation, counter-current flow, PWR hot leg, parallel wire array probe, stochastic analysis.

Abstract

Abstract This study investigated the use of active sachets that emit volatile antimicrobial compounds — ethanol, with and without the addition of cinnamon oil (CO) — to extend the shelf-life of packaged sweetbread. The addition of CO was expected to mask any undesirable odor from ethanol and enhance its antimicrobial efficacy. The active sachets contained ethanol emitter (EE) only and EE combined with CO (ECOE) at the dose of 0.5 and 1 times the minimum inhibitory concentration (MIC). The effects of active sachets were evaluated based on mold (Rhizopus stolonifer) growth inhibition, hardness, and sensory properties of the packaged sweetbread. The obtained results showed that the mold growth fully covered the Petri dish containing potato dextrose agar (PDA) in 3 days and 4 days in samples without an active sachet and with the EE sachet, respectively. Interestingly, there was no mold growth in samples containing active sachets ECOE 0.5 MIC and 1 MIC. The hardness of the sweetbread, measured with a texture analyzer, was 2105.2 gf for the control, 1375.0 gf for EE, 1313.0 gf for ECOE 0.5 MIC, and 1224.8 gf for ECOE 1 MIC, thus indicating a slower staling rate when using active sachets. Sensory evaluation revealed that there was no significant difference (p > 0.05) in the overall acceptance parameter between sweetbread packaged with and without active sachets (EE and ECOE) treatments indicating there was no decreasing consumer preference. The addition of CO to ethanol emitters enhanced the extension of the shelf-life of packaged sweetbread by inhibiting mold growth and reducing staling without decreasing sensory quality.

Abstract

The occurrence of flood disasters is an annual unavoidable event in the Mejobo District, Kudus Regency. This study aims to map the vulnerable areas to floods in the Mejobo District using spatial modelling. The parameters used to determine the vulnerability areas include soil type, elevation, population density, river buffer, rainfall, and land use. The research location is situated in the Mejobo District. The research method employed is the models and multicriteria decision-making (MCDM) techniques, with the assistance of ArcGIS software for data processing and analysis. The research findings yield a final map depicting flood vulnerability, which indicates the distribution of flood-prone areas. Areas with a high level of flood vulnerability are dispersed across agricultural fields and areas adjacent to rivers, covering an area of 1,770 hectares. Meanwhile, areas with a moderate level of vulnerability are predominantly distributed in residential areas, covering an area of 1,907 hectares.

Abstract

Chia and basil seeds are a plant-based source that possess unique characteristic, including the ability to form a gel when hydrated due to polysaccharide layer on outer seeds can absorb water This property can be applied to food products that may easily suffer texture damage such as yogurt. Therefore, further research is needed to determine the potential of chia and basil seeds as a hydrocolloid source that can affect yogurt characteristics and total lactic acid bacteria (LAB). Chia and basil seeds in this study were each processed into two treatments: flour and hydration of whole seeds (1:30). Each treatment was added to yogurt formulation with concentration: 0, 1, 2, and 3% (w/v), then evaluated by preference test to determine selected formulation. Two formulations that were organoleptically preferred by panelists were yogurt with hydrated chia 2% and hydrated basil 3% according to hedonic rating test. The selected formulations were proximate content analysis, syneresis, viscosity, and total LAB. The addition of chia and basil seeds into yoghurt had significant effects on syneresis and viscosity at a significance level of 5%. The syneresis of yogurt with hydrated chia 2% was 1.37±0.21% while the syneresis of yogurt with hydrated basil 3% was 0.58±0.05% which was lower than control 2.44±0.24%. Viscosity of yogurt with hydrated chia 2% was 3808.33±38.19 cP and yogurt with hydrated basil 3% was 4175.00±25.00 cP, which was higher than control 3116.67±28.87 cP. Total LAB in chia yogurt reaching 1.1×109 CFU/g and basil yogurt reaching 1.2×109 CFU/g was higher than control 8.7×107 CFU/g. Overall, the addition of chia and basil seeds improved the quality of yogurt.

Abstract

White tea is a plant-derived product from Camellia sinensis L, which is processed without enzymatic oxidation and fermentation. The high identity traits (HITS) is a sensory evaluation method that identifies dominant attributes using five attributes to describe each sample. The sensory evaluation research on white tea uses the HITS method with an environmental approach aimed at identifying dominant attributes of white tea using both trained and untrained panelists, as well as at determining the intensity of these dominant attributes using an environmental approach with both trained and untrained panelists. The materials used were five samples of Gamboeng white tea, Heizl, Dandang, Pucuk, and Ennie1. The HITS method with trained panelists successfully identified dominant attributes as follows: yellow-brown brew color, rose aroma, rose flavor, astringent aftertaste, and light mouthfeel. Meanwhile, the experiment using untrained panelists showed dominant attributes as follows: yellow-brown brew color, jasmine aroma, jasmine flavor, astringent aftertaste, and light mouthfeel. The HITS method with an immersive approach for both trained and untrained panelists had an impact on increasing the intensity of aroma, flavor, and mouthfeel while decreasing the intensity of aftertaste.
