Abstract

Beet tubers are perishable horticultural commodities, cannot be stored for long, and are commonly consumed in fresh conditions. Postharvest handling of beet tubers needs to be carried out to maintain their freshness Chitosan and other packaging used in postharvest handling of fresh beet tubers have not yet been reported. This study aims to determine the effect of chitosan coating and types of packaging on beet tubers on the physical quality of beet tubers. The study was a randomly designed group with two factors; the first factor was chitosan concentration, and the second factor was the kinds of packaging. Chitosan concentration consists of 5 levels, namely 0, 0.5%, 1%, 1.5%, and 2%, and the type of packaging includes no packaging (Without), plastic packaging with holes (Perforated), ordinary plastic packaging (Ordinary) and plastic vacuumed (Vacuum). The beet tubers were soaked in chitosan solution of 0, 0.5%, 1%, 1.5%, and 2% for 1 minute, air-dried, then were packaged with no packaging, plastic packaging with holes, ordinary plastic packaging, and plastic vacuumed. .  The physical quality parameters observed were moisture content, weight loss respiration rate,electrolyte leakage, total dissolved solid (TDS), ascorbic acid, betacyanin, betaxanthins,  tuber firmness, damage percentage, and visual quality rating (VQR). Data were analyzed using Anova variant analysis and then continued with Tuckey tests with a 95% confidence level using R studio software. The results showed that chitosan coating did not affect the physical quality of beet tubers, while packaging affected the quality of beet tubers. The most suitable packaging to maintain the physical quality of beet tubers is plastic packaging with holes (perforated).

Abstract

Temulawak (Curcuma xanthorrhiza Roxb.) is a plant native to Indonesia with many benefits. The need for temulawak is increasing along with the increasing public awareness to consume traditional medicine instead of chemical drugs. It has led to increased demand for temulawak by the traditional medicine industry. The demand and supply of temulawak must be maintained to avoid oversupply scarcity. This study aims to build a simulation model of temulawak supply sustainability in East Java using a system dynamic approach and the ratio of supply and demand (S/D ratio). System dynamic modeling was chosen to model the condition of the temulawak availability system in determining medium-term strategies. System dynamic are very appropriate for simulating policies and evaluating the condition of the temulawak availability system. This study considered three scenarios: expanding temulawak land by 5%, increasing temulawak productivity to 20 kg/m2, and a combination of the first and second scenarios. The results showed that the most effective policy was scenario three, by combining the policy of expanding agricultural land by 5% and increasing temulawak productivity to 20 kg/m2, with this policy model being able to maintain the S/D Ratio 1 for the next 5 years.

Abstract

Opak is a traditional food from Indonesia made from fresh cassava. But fresh cassava has short shelf life because of the undergoing post-harvesting physiological deterioration shortly after harvest. Therefore, this research tried to replace the fresh cassava with cassava flour as a raw material for opak production. The purpose of this study are to determine the thickness and drying time in the production of opak from cassava flour which produces the best sensory, physical and chemical properties. Opak was made with thickens variations of (K1) 0.5 mm, (K2) 1 mm, (K3) 1.5 mm, and (K4) 2 mm with drying time variations of (P1) 1 hour, (P2) 2 hours, and (P3) 3 hours. The results show that there has interaction effect between thickness and drying time toward the best opak cassava flour, namely 1 mm thickness with 3 hours drying time with color characteristics 1.40 (brownish yellow), texture 4.02 (crispy), flavour 3.2 (slightly typical of cassava), the bulk density was 0.59 g/mL, the water absorption capacity was 5.49 %, and the oil absorption capacity was 0.03 g/g, the moisture is 0.20 %, the ash content is 2.89 %, the protein content is 1.26, fat content 27.12 %, and 68.51 % of carbohydrates.

Abstract

The coffee agroindustry in Indonesia, particularly in Malang Raya, has undergone expansion through the increased development of coffee processing industries, including waste and emissions. Various factors, including farming practices, land use, waste management, and the utilization of by-products influence the emission levels in the supply chain. A value chain analysis in supply chain management is essential to support sustainable coffee agroindustry. The complexity of the coffee value chain involves multiple stakeholders, including input providers, producers, traders, cooperatives, and exporters, emphasizing the intricate nature of the coffee chain and the need for coordinated efforts to ensure quality and sustainability. This research aims to identify emission sources in the supply chain and determine the economic impact of coffee production at the farmer level. The value chain operations reference is the method used for measuring the value chain. The calculation results indicate that the carbon emission footprint in the supply chain activities at the farmer level amounts to 22,734 kg CO2 with a unit cost of 0.75 €/kg. These values suggest that activities in the coffee value chain at the farmer level are still not environmentally friendly (intolerable region). Suggested approaches for enhancing the value chain for coffee farmers in Karangploso encompass the installation of a smart GPS system in vehicles for route optimization and fuel efficiency, and using organic fertilizers instead of chemical fertilizers to prevent water pollution, along with the adoption of an organic farming system to enhance the economic value of the harvest. The findings of this study are expected to be a reference for research on the value chain in coffee supply chain activities, and contribute to the enrichment of information related to the VCOR model

Abstract

Coconut oil processing using traditional methods involving high temperatures can damage the oil's structure and quality, leading to rancidity and reduced nutritional value. To address this, alternative methods like salting are essential for producing high-quality Virgin Coconut Oil (VCO) that meets industry standards. This study aims to evaluate the effect of salt concentration and incubation time on the yield, water content, free fatty acids, and organoleptic properties of VCO. The research employed a Completely Randomized Design (CRD) with two factors: salt concentration (4 grams, 6 grams, and 8 grams) and incubation time (12, 24, and 36 hours). Statistical analysis using ANOVA at a 95 % significance level followed by post-hoc tests was conducted to assess the treatment differences. Results showed that a 6-gram salt concentration combined with a 12-hour incubation yielded the best results in terms of yield, water content, and overall quality. The water content ranged from 0.06 % to 0.14 %, adhering to the Indonesian National Standard (SNI 7381:2008), which limits water content to 0.2 %. Free fatty acids were also low, with an acid value ≤ 0.2 %, well within SNI limits. Organoleptic tests revealed that consumers preferred VCO made with 6 grams of salt and a 12-hour incubation. This formulation produced oil with a clear, attractive color, a fragrant aroma, and a pleasant coconut flavor. Overall, the salting method proved highly effective for producing premium VCO. Not only did the oil meet standard quality parameters, but it also had a longer shelf life, making it suitable for health and culinary uses. This study concludes that salting is a cost-effective, efficient method for producing high-quality VCO, offering a viable alternative to traditional high-temperature methods.

Abstract

Managing sugarcane harvesting and loading activities can increase the efficiency of sugar factory production. Scheduling this activity has a significant impact on reducing harvesting and loading costs, reducing the area of harvested land, and optimizing sugar production capacity. This study was conducted at a private sugar factory in Malang to develop a sugarcane harvesting and loading scheduling model. This model aims to optimize the sugar harvesting and transport scheduling so that the cost is lower and the sugar production capacity can be met. The model is built using LINGO 11.0 software. The results of the study showed significant improvements, namely the cost of harvesting and loading sugarcane decreased by 33.1% from Rp.  1.90 billion to Rp. 1.27 billion. Meanwhile, the harvested area decreased from 139.69 ha to 137.87 ha. In addition, sugarcane production increased by 24.6% from 11,140 tons to 13,887 tons per milling season, and the need for vehicles decreased by 39% from 2,870 to 1,736 units. The simulation results were then formed into a table containing a detailed schedule of harvesting and loading sugarcane as a recommendation to improve operational efficiency and factory profitability.

Abstract

An edible coating is a thin layer of hydrocolloid materials such as polysaccharides, polypeptides, lipids, and composites. Apples are one of the fruits that often undergo minimal processing, such as slicing. Cut apples are susceptible to damage, which can lead to rapid browning, to slow this reaction, an edible coating can be applied. This study aimed to determine the quality of apple slices after being treated with an edible coating made from arrowroot starch with lime juice and mint leaf during storage. This study used a Completely Randomised Design with two factors: storage time (0, 2, 4, and 6 days) and the concentration of lime juice and mint leaf. The results showed that adding lime juice and mint leaf did not significantly affect water content, vitamin C, and weight loss of apple slices, while the longer the storage, the more damaged the sliced apples were. Weight loss, antioxidant activity, total phenols, vitamin C, and total aerobic bacteria decreased during storage. The treatment of adding 13% lime juice and 10% mint leaves was able to suppress the total number of bacteria to 5.77 log 10 CFU / g at a shelf life of 6 days. The treatment of adding mint leaves and lime extract was able to inhibit damage to sliced apples for 6 days of storage

Abstract

The palm oil industry produces solid waste, particularly empty oil palm fruit bunches. The lignin contained in these empty bunches functions to make the wood resistant to microbial attack. Meanwhile, coffee horn skin waste is not used optimally. This research aims to utilize waste coffee horn skin and empty oil palm fruit bunches as alternative raw materials for making particle boards. Empty oil palm bunches and coffee husks are dried in the sun to reduce the water content of products and ensure the fiber becomes dry. Empty bunches and dried horn skin are then soaked using a mixture of NaOH and distilled water. The resulting fibers that have been chopped are then dried. The resulting dried fibers are reduced in size again. There are 7 different ratios that are used in fiber mass between empty bunches plam fruit and coffee husk. Every particle board was built in dimensions of 25 x 25 x 5cm and pressed for 10 minutes. The research results obtained in the form of board particle density tests showed significant differences in all treatments, and the density test results met SNI 03-2105-2006. Apart from that, there is no real difference in the test results for the particle board water content, so it meets SNI 03-2105-2006. Tests for the development of thick board particles showed that there were significant differences in all ratios, namely that P1, P2, P5 met SNI 03-2105-2006 and P3, P4, P6, P7 did not meet SNI 03-2105-2006. In the elastic modulus and fracture modulus tests, there were no differences in all treatments. However, they did not meet SNI 03-2105-2006, whereas, in the particle board absorbency test, there were significant differences in all treatments and the absorbency test results were still relatively high. However, SNI 03-2105-2006 does not specify standard values for air absorbency.

Abstract

Meats of consumable livestock for humans are commonly from ruminants, such as cows, goats, lambs, buffaloes, etc. The method of slaughtering the livestock at the slaughterhouse mostly applies non-stunning or stunning methods. The stunning method uses electricity, mechanics, and gas. The slaughtering methods influence the meat quality and results. Thus, further meta-analysis is important to provide valid and informative conclusions based on comprehensive investigations about the slaughtering method's effect on ruminant meat quality. The researchers applied the PRISMA diagram and the size of the Standard Mean Difference effect, SMD, with Hedge's formulation as the quantitative synthetical meta-analysis method. The results found that the slaughtering method with stunning and non-stunning methods did not significantly influence some parameters, such as pH, colors (L*, a*, and b*), the water holding capacity, cooking loss, and shear force. However, the methods significantly influenced the drip loss and myofibril fragmentation index parameters with SMD values 0.2, p-values 0.001 to 0.777, and heterogeneity values of 0% to 82.98%.
