Dragon fruit peels (Hylocereus polyrhizus) are generally only considered trash by the public because they are considered useless, even though dragon fruit peels still contain useful nutrients. Dragon fruit skin can be used as food, one of which is a jam. The addition of pineapple fruit variations to dragon fruit peel jam as a flavor enhancer and natural fragrance to reduce the use of sugar in jam and the aroma of pineapple fruit can mask the distinctive aroma of dragon fruit which is less desirable. The purpose of this study was to determine the appropriate concentration variations in the manufacture of dragon fruit peel jam with the addition of pineapple, which consumers liked. This study used a completely randomized design with six (6) treatments and two (2) replications. Dragon fruit peel jams analyzed by chemical tests included moisture content, sugar level, and pH, while organoleptic test included color, texture, taste, aroma, and a total of 30 untrained panelists. Observation data were processed using ANOVA (α = 5%) and further tested using the honest significant difference test (BNJ) (α = 5%). The results showed that the pineapple’s addition to dragon fruit peel jam had a very significant effect on the panelists' preference for aroma and taste, but not significantly different from the color, texture, and chemical characteristics of jam. The N6 treatment (dragon fruit peel 250 g: pineapple fruit 250 g) was the best jam, based on chemical characteristics (pH content of 3.52, moisture content of 18.65%, sugar level of 53.30%) and preferable in organoleptic characteristics (2.97 of color, 2.97 of texture, 2.97 of flavor, 3.00 of taste).

Kersen trees (Muntingia calabura L.) are included in the Elaeocarpaceae family and are mostly used as a protective tree. The kersen leaves were an environmental waste (trash) and still lacks implementation in food processing. This study was aimed to determine the chemical characteristics and antioxidant activity of kersen leaves at different altitudes and their potential as an herbal tea. The difference in the height of the place to grow will be used as a factor to be studied so that this study uses a completely randomized design with a one factor pattern (height the place of growings). Kersen leaves were taken from three districts, namely Jember (83 amsl/above mean sea level), Situbondo (5 amsl), and Bondowoso (255 amsl). The results showed that the chemical characteristics of kersen leaves consisting of moisture content, ash content, fat content, and carbohydrate content were not significantly different between regions, while protein content and antioxidant activity levels were significantly different between regions.

The abundance of cassava, especially during the main harvest, triggers the accumulation of damaged cassava due to lack of processing and storage. An alternative solution to overcome this problem is by processing it into fried frozen cassava. The freezing process could extend product shelf life. In addition, it is necessary to have additional materials such as sodium bicarbonate to improve physical characteristics because it can form air cavities which make the product becomes more crispy outside and soft inside. The aim of this study was to determine the effect of variations in boiling time and sodium bicarbonate on the characteristic of fried frozen cassava. This study used 8 types of sample variation, 4 levels of factor A (boiling time: A0=0 min; A1=10 min; A2=20 min; A3=30 min) and 2 levels of factor B (sodium bicarbonate: B1=without soaking in sodium bicarbonate; B2=with soaking in sodium bicarbonate). Based on the results of the study, soaking in sodium bicarbonate and boiling time variations gave a significant effect on the texture of fried frozen cassava (value range 4-56 g/mm) but not on lightness (value range 64-71). The assessment from organoleptic characteristic (value range on color/lightness 2.63-3.48, aroma 2.51–3.40, flavor 1.75–3.92, texture 1.51–3.94, overall 1.81–3.81), showed that the fried frozen cassava with 30 minutes boiling time was preferred by consumers, especially those which soaked in sodium bicarbonate.

Opaque soap is a solid soap product. It was made from a mixture of oil and the addition of alkaline compounds to form a saponification process. Solid soap preparations made with the addition of tobacco extract as an active ingredient that contains nicotine compounds, which include toxic alkaloids are weakly basic. In addition, tobacco extracts chosen to produce products that were beneficial to society. The purpose of this study was to provided wider use of tobacco and to know the characteristic of opaque soap preparations with the addition of tobacco extracts. The research method was a single completely randomized design (CRD) with descriptive analysis. In this study, the formulas of opaque soap were A0 (no addition of tobacco extract), A1 (1.2 g of tobacco extract), A2 (2.4 g of tobacco extract), and A3 (4.8 g of tobacco extract). The observed parameters were chemical and microbiological characteristics. All variations of opaque soaps had a pH of 9.51-9.77, water content of 13.15%-14.35%, free alkali 0.056-0.0584, antibacterial (E. coli inhibition zone proved by clear zone) about 8.60-21.50 mm; and nicotine levels 0-383.67 mg/100g. From the results due to chemical and microbiological characteristics, all of the opaque soap with additional tobacco extract was in accordance with the Indonesian National Standards (SNI 3532-2016) so that soap was safe for use by the public.

Packaging refers to an object to protect and secure certain products within the package as well as giving a particular image to persuade the customers. The research objectives were to identify customers’ desires and satisfaction levels to prol tape product packaging using the quality function deployment (QFD) method, designing packages, determining the type of packaging, and determining the compressive strength of the packaging using a universal testing machine (UTM). The research findings were 4 important attributes found for secondary packaging, namely the attributes of strength, appearance, price, and protection. Based on the attributes, the researcher designed a new secondary packaging using the RSC (regular slotted container) type of packaging consisting of two parts; BC flute type for outer packaging and B flute type for inner packaging. Meanwhile, the old secondary packaging only consisted of one part, namely B flute type for outer packaging. According to the compressive strength test results, the new packaging has a compressive strength value of 189.6 kgf with a maximum stack number of 40 stacks, and the old packaging has a compressive strength value of 82.7 kgf with a maximum stack number of 18 stacks.

The demand for amplang crackers is now increasing. However, the price of its raw material, mackerel fish, is generally higher compare to other fishes, causing the higher cost of this type crackers production. Effort to explore other fish as an alternative raw material is required to overcome the problems. Catfish is one of the choices to be used as raw material since this fish is more available in a market in a lower price, but the protein properties of this fish is different to mackarel, which will be possible to affect the nature of the crackers obtained. To produce catfish amplang crackers to be similar to common amplang product, it is necessary to find out the right composition of catfish and tapioca flour used. Therefore, the purpose of this research was to characterize physico-chemically and organoleptically, the catfish amplang crackers made under different ratio of fish flesh and starch. The experiment was designed using completely randomized design. Physico-chemical data obtained were analyzed using ANOVA, while the organoleptic test data were examined using chi-square method. The effectiveness test was carried out to find the proper ratio of raw materials composition used. The results showed that the higher the ratio of the fish flesh and the starch composition, the lower the texture value of the crackers as an indication of the decrease of its crispness. Although the lightness of the crackers was lowered by the addition of more starch to the dough, its linear expansion and hygroscopicity were not affected. The results of organoleptic test showed that the panelist was prefer to a higher crispness of crackers. The most preferable cracker was the one with 1:2.25 ratio of catfish flesh and starch, showing the characteristic of 1.80% moisture, 2.08% ash, 5.75% protein, 23.55% fat, and 66,93% carbohydrate.

Catfish is one of the choices to be used as raw material since this fish is more available in a market in a lower price, but the protein properties of this fish is different to mackarel, which will be possible to affect the nature of the crackers obtained. To produce catfish amplang crackers to be similar to common amplang product, it is necessary to find out the right composition of catfish and tapioca flour used. Therefore, the purpose of this research was to characterize physico-chemically and organoleptically, the catfish amplang crackers made under different ratio of fish flesh and starch. The experiment was designed using completely randomized design. Physico-chemical data obtained were analyzed using ANOVA, while the organoleptic test data were examined using chi-square method. The effectiveness test was carried out to find the proper ratio of raw materials composition used. The results showed that the higher the ratio of the fish flesh and the starch composition, the lower the texture value of the crackers as an indication of the decrease of its crispness. Although the lightness of the crackers was lowered by the addition of more starch to the dough, its linear expansion and hygroscopicity were not affected. The results of organoleptic test showed that the panelist was prefer to a higher crispness of crackers. The most preferable cracker was the one with 1:2.25 ratio of catfish flesh and starch, showing the characteristic of 1.80% moisture, 2.08% ash, 5.75% protein, 23.55% fat, and 66,93% carbohydrate. \u0000Keywords: cracker, catfish, tapioca starch","PeriodicalId":340373,"journal":{"name":"Jurnal Agroteknologi","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120913870","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Agroindustry is an industry that processes agricultural products from raw materials. Agroindustry increase the added value of agricultural commodities. Virgin coconut oil (VCO) product have high economic value because it has many benefits for health and beauty care as well. One of the industries processing coconut into a VCO product in Jember on an SME (Small Medium Enterprises) scale is located in Sukorejo, Jember Regency. The economic feasibility showed that its VCO industry business had a positive NPV. The BC Ratio value less than 1, which means that cash in flow was bigger than cash out flow, in the present value called Break Even Point (BEP), that is, total cost equals total revenue. IRR value that is generated is greater > 6% loan interest, and the last payback period (PBP), which is produced shows the value (less than) <10 years. In accordance with the specified time period of 5 years and 4 months. From the results of the analysis, it can be said that the VCO industry in Sukorejo, Sumbersari District was feasible to do. Keywords: economic feasibility, virgin coconut oil

Star apple is a seasonal local fruit that is commonly found in East Java, Indonesia. This fruit contains high fiber and antioxidants, however the utilization was not optimal specially at the harvest season, so it requires for further processing. Star fruit apple processing into fruit leather would expected to resolve this problem. Plasticity is an important parameter in fruit leather quality which can be influenced by binding agent, sugar, and acid composition. Therefore, the aim of this study was to determine the best concentration of binding agent that can produce star apple fruit leathers with good characteristics and preferred by consumers. The concentration of CMC and carrageenan used in this study were 0.1%; 0.3%; 0.5%. Physicochemical data were analyzed by ANOVA (α = 5%) and DMRT, while preference were analyzed using Chi-square test (α = 5%). The best treatment determination was using scoring analysis. The result showed that 0.3% carrageenan was the best treatment to produce star apple fruit leather with 54.48 lightness; 348 g/ 2 mm texture; 17.99 KPa tensile strength; 9.03% elongation; 2.68% syneresis; 22.49% water content; and 6.11% crude fiber content. While the color, aroma, texture, taste, and overall preference were as follows 73.33%; 63.33%; 73.33%; 60%; and 66.67% respectively. Keywords: CMC, carrageenan, fruit leather, star apple
