Abstract

Kandis acid is one of the spices that is often used for cooking and health ingredient. Processing kandis acid fruit skin is by the drying process. Drying can be done using tools or in the sun. Drying using tools is still not optimal because there is no temperature control during drying, this study drying was carried out using an arduino-based oven so that the initial temperature could be determined and the temperature during drying could be controlled. This study aims to evaluate the drying temperature control in an arduino uno-based oven and also to evaluate the drying method used on the quality of the kandis acid produced. Based on the research that has been done, controlling the drying temperature using an arduino uno-based oven that has been running well, the oven automatically controls the drying temperature to return to the set point temperature used (60 0C). The best quality of kandis acid is drying using a tool, seen from observations such as mold growth, drying time and drying rate. However, in drying using the sun, the value of vitamin C has a higher value than drying using a tool. The rind of the kandis acid used was 2,7 kg in each drying, the initial moisture content in drying using a tool was 83,289% with a final moisture content of 9,672% and the initial moisture content drying using sunlight was 83,744% with a final moisture content of 10,796%. The drying time for drying using a tool is 9,3 hours with a drying rate of 0,041 kg/hour, while for drying using sunlight was 20,7 hours with a drying rate of 0,036 kg/hour.

Abstract

          Kualitas buah sangat berpengaruh pada tingkat daya tarik konsumen, salah satunya pada bentuk buah. Umumnya proses pengelompokan mutu buah menggunakan pengamatan secara visual. Cara ini kurang efisien dan membutuhkan waktu lama. Metode untuk mengatasi masalah tersebut adalah dengan analisis citra digital, yang merupakan ruang lingkup suatu sistem mengenai teknik mengolah dan menganalisa citra atau gambar dengan meggunakan komputer. Tujuan penelitian ini yaitu mengidentifikasi bentuk fisik dari buah alpukat yang normal dan kurang normal dengan analisis citra digital. Pengelompokkannya sesuai dengan standar mutu I dan II buah alpukat, yaitu normal dan kurang normal. Agar terlihat perbedaannya dilakukan menggunakan beberapa parameter bentuk meliputi roundness, sphericity, dan nilai K. Perhitungan tiga parameter ini dilakukan dalam dua kondisi yaitu perhitungan manual dan analisis citra. Hasil penelitian menunjukkan roundness manual normal diperoleh nilai 0,850 sampai 0,893 dan kurang normal diperoleh nilai 0,851 sampai 0,905. Roundness citra normal diperoleh nilai 0,856 sampai 0,895 dan kurang normal diperoleh nilai 0,856 sampai 0,897. Sphericity manual normal diperoleh nilai 0,810 sampai 0,941 dan kurang normal diperoleh nilai 0,807 sampai 0,953. Sphericity citra normal diperoleh nilai 0,826 sampai 0,945 dan kurang normal diperoleh nilai 0,837 sampai 0,972.

Abstract

Minimally processed jackfruits can usually be found in traditional markets, but the fact found that jackfruit is sold unpackaged and the fruit is not fresh, some have even browned and are infested with flies. Refrigerator is usually applied, but this technology is relatively expensive and not all farmers/traders can afford it. Edible film is an alternative that is easily degraded and decomposed by natural composers plus zinc oxide (ZnO) which is a piezoelectric ceramic that has anti-microbial properties. The purpose of this research was to determine the effect of ZnO concentration on the characteristics of edible films and to determine the best concentration of ZnO and its effect on packaging in jackfruit. Variations in the concentration of ZnO used 0%, 3%, 9% and 12%. Observations on jackfruit were carried out at room temperature. Results showed the higher the concentration of ZnO, the better the ability of edible films with ZnO to maintain the quality and shelf life of jackfruit. Edible film with 12% ZnO was able to extend the shelf life of processed jackfruit for at least 5 days at room temperature . Keywords:  Hardness, Weight loss, Total dissolved solid, Microbial test, Water content.

Abstract

Plastic is one of the most widely used packaging materials. Plastic is made of chemicals that are highly toxic, and its use has produced a lot of waste that is bad for the environment and difficult to decompose. The global community is becoming more and more aware of the value of high-quality food, particularly when it comes to packaging that is safe for human health and the environment. Edible films can be used as an eco-friendly alternative to plastic food packaging options. As a material for packaging, edible film made of biopolymers has been created. This material can be made from biodegradable components and has qualities akin to those of ordinary plastics. When combined with zinc oxide (ZnO), a piezoelectric ceramic with anti-microbial properties, edible film degrades and decomposes readily. This study sets out to identify the effects of variations in zinc oxide nanoparticle concentration properties of edible films made from corn starch (Zea mays L.) and to establish the optimal zinc oxide nanoparticle concentration. ZnO concentrations ranging from 0% to 3% to 9% to 12% were used. The outcomes demonstrated that a concentration of 12% provided the optimal treatment for the properties of edible film. With the addition of 12% ZnO concentration, the edible film's properties improved the most in this investigation, showing 81.94% water resistance, 1.434 MPa tensile strength, and 38.46% elongation percent. The lowest biodegradability value was found in edible film with a concentration of ZnO 12%, within 14 days. The resistivity, tensile strength, and % elongation of the edible film increase with increasing ZnO content.

Abstract

Abstrak. Pisang Cavendish merupakan salah satu jenis pisang yang cukup potensial dan banyak dikonsumsi oleh masyarakat, baik untuk olahan maupun untuk santapan segar. Pisang merupakan buah klimakterik yang tetap mengalami proses kematangan walaupun telah dipanen dan diikuti dengan proses kerusakan karena buah tetap melangsungkan proses respirasi dan metabolisme (Sumadi, et al., 2004). Hal ini merupakan kendala dalam upaya memperpanjang umur simpan buah pisang Cavendish. Cara mengatasi permasalahan tersebut yaitu dengan melakukan perbaikan penanganan pascapanen, agar kualitasnya dapat dipertahankan setelah panen dilakukan. Pelilinan dan pemilihan media simpan merupakan salah satu teknologi pascapanen dalam mempertahankan mutu produk yang berfungsi mengurangi kerusakan produk pertanian akibat proses respirasi. Tujuan dilakukannya penelitian ini adalah untuk mengkaji pengaruh media simpan berupa pasir dan serbuk gergaji terhadap mutu dan umur simpan pisang yang telah dilapisi lilin selama penyimpanan. Pemberian jenis media simpan selama penyimpanan buah pisang berpengaruh terhadap mutu pisang yaitu nilai kerusakan mekanis, susut bobot, TPT, hue, kekerasan dan kadar air buah pisang selama penyimpanan. Umur simpan buah pisang yang terlama terdapat pada perlakuan ada pemberian media simpan serbuk gergaji (A0M1) dengan 15 hari umur simpan. Study Media Types Storage on Cavendish Banana Quality (Musa parasidiaca ‘Cavendish’) Abstract. Cavendish banana is one type of banana is quite potential and widely consumed by the community, both for processing and for fresh cuisine. Banana is a climacteric fruit that continues to experience the process of maturity although it has been harvested and followed by the destruction process because the fruit continues the process of respiration and metabolism (Sumadi, et al., 2004). This is an obstacle in an effort to extend the life of the Cavendish banana shelf. How to overcome these problems is to make improvements postharvest handling, so that quality can be maintained after harvest is done. Pelilinan and the selection of media store is one of the postharvest technology in maintaining product quality that serves to reduce the damage of agricultural products due to respiration process. The purpose of this research is to examine the effect of storage media in the form of sand and sawdust on the quality and life of banana shelf that has been coated wax during storage. Giving the type of storage media during the storage of bananas affect the quality of bananas are the value of mechanical damage, weight loss, TPT, hue, hardness and moisture content of bananas during storage. The oldest banana-saving age was found in the treatment of sawdust storage media (A0M1) with 15 days of shelf life. fermentation box to the environment in the outside. The results showed that the ideal temperature of fermentation in wooden boxes was obtained in the fifth day, while the ideal temperature of fermentation in Styrofoam was obtained in the third day. Heat transfer in the wood material is higher than in the Styrofoam material. This was due of the heat in a wooden box go out faster, so that the temperature in the fermentation process may be lower than using a Styrofoam box. The result of cocoa seed fermentation using a wooden box obtained a good cocoa seed on the fifth day of fermentation and while using a Styrofoam box cocoa seed were moldy in the fifth day.
