Abstract

Penanganan pascapanen adalah hal penting yang perlu diperhatikan oleh seluruh aktor di suatu rantai pasok hingga sampai ke tangan konsumen. Evaluasi penerapan penanganan pascapanen sesuai standard operating procedure (SOP) perlu dilakukan agar dapat menemukan pada tahap-tahap mana saja yang perlu diperbaiki sehingga mutu produk lebih dapat terjaga. Tujuan penelitian ini adalah mengidentifikasi penanganan dan penerapan SOP pascapanen tomat, serta mengidentifikasi permasalahan penanganan pascapanen tomat yang dihadapi oleh aktor. Aktor yang terlibat pada rantai pasok adalah petani, pengepul, pedagang eceran dan konsumen. Metode pemilihan responden awal menggunakan purposive sampling yakni pemilihan petani di Desa Perbawati, Sukabumi dan dibedakan menjadi tiga tipe petani berdasarkan luas lahan yang dimiliki. Pemilihan responden selanjutnya menggunakan metode snowball sampling hingga responden akhir yakni konsumen. Penerapan SOP diperoleh dari wawancara dan observasi lapang. Parameter yang digunakan adalah membandingkan penanganan pascapanen yang dilakukan oleh aktor dan dibandingkan dengan SOP yang telah disusun oleh Direktorat Budidaya dan Pascapanen Sayuran dan Tanaman Obat, Direktorat Jenderal Hortikultura Kementerian Pertanian dan dilakukan perhitungan persentase kesesuaian dan upaya perbaikan yang diperlukan. Pada penelitian ini didapatkan kesesuaian penerapan SOP sebesar 54,44% dan diperlukan perbaikan sebesar 45,56%. Hal ini menunjukkan kesesuaian antara SOP dan pelaksanaan di lapang pada tingkat petani, pengepul, maupun pedagang eceran kondisi lingkungan panas menjadikan produk terpapar sinar matahari secara langsung serta kebersihan yang kurang dijaga membuat kualitas produk mudah menurun. Study Implementation of Standard Operating Procedure on Post-Harvest Tomato and Problems Faced by Actors in the Supply Chain.Postharvest handling is an important part that needs to be considered by actors in a supply chain until it reaches consumers. Evaluation of the implementation of postharvest handling according to the standard operating procedure (SOP) needs to be done to be able to find at what stages need to be improved so the product quality can be maintained well. This study aimed to identify the handling and the SOP implementation postharvest tomatoes, also identify the problems of handling postharvest tomatoes faced by the actors. The actors involved in the supply chain are farmers, collectors, retailers, and consumers. The first actors as respondents selected by the purposive sampling method were farmers in Perbawati Village, Sukabumi, and divided into three types of farmers based on the area of land they have. The next respondents selected by the snowball sampling method to the consumer as final respondents. The application of SOP obtained from interviews and real observations. The parameters used were comparing postharvest handling carried out by the actors and compared with SOP that has been published by the Directorate of Vegetable and Postharvest Cultivation and Medicinal Plants, Directorate General of Horticulture, Ministry of Agriculture and calculating the percentage of suitability and the percentage of improvement needed. In this study, the suitability of SOP implementation was 54.44% and 45.56% improvement was needed. These results showed the compatibility between the SOP and the implementation in the field at the level of farmers, collectors, and retail that high temperature of environmental conditions made the product exposed to direct sunlight and low maintained hygiene made the quality of the product easy to decrease.

Abstract

Part of the cassava that can be used as a food product is usually starch and and the waste is cassava bagasse. Fermented cassava bagasse flour is a modified semi-solid fermentation product using yeast Saccharomyces cerevisiae which has almost the same quality as modified cassava flour (mocaf), but fermented cassava bagasse flour has advantages compared to mocaf flour, namely high protein content and cheaper production costs. Fermented cassava bagasse flour has various functions which can be used as raw material for the manufacture of various processed products, one of which is cassava stick. The research objective was to see the formulation of fermented cassava bagasse flour to the sensory characteristics of the resulting cassava stick. The study was conducted using a completely randomized design (CRD) including 5 treatment methods, namely cassava starch substituted by fermented cassava bagasse flour 5% (B1), 10% (B2), 15% (B3), 20% (B4) and 25% (B5), each treatment was repeated 3 times. Based on the sensory results, it was obtained that 15% (B3) fermented cassava bagasse flour substitution treatment was the best choice of cassava stick product by panelists. The results of the analysis of cassava stick products were hardness test 3,77 µ (kg / cm2) ; swelling ratio 18,33% ; moisture content 2,20% ; ash content 0,14% ; protein content 10,00% ; fat content 21,00% ; fiber content 0,17%; carbohydrate content 66,49% and total dietary fiber 21,24%.

Abstract

Pengolahan ubi kayu segar menjadi tepung merupakan salah satu alternatif untuk mengatasi sifat fisiologis ubi kayu yang mempunyai umur simpan yang relatif singkat. Akan tetapi, pada umumnya tepung ubi kayu yang diproses secara tradisional dari gaplek memiliki beberapa kelemahan. Kelemahan ini antara lain kurang mengembang pada tingkat proporsi yang tinggi, tekstur produk relatif keras, serta aroma apek (musty) ubi kayu kering yang terbentuk karena reaksi lanjut dari proses kerusakan fisiologi pasca panen saat penjemuran gaplek. Komponen aroma musty ini sering kali masih terbawa ketika diaplikasikan pada produk olahannya. Upaya untuk memperbaiki kualitas tepung umbi-umbian telah banyak dilakukan termasuk penggunaan panas. Blansing dalam air panas telah dilaporkan dapat memperbaiki kualitas produk kering berbasis hortikultur. Tujuan penelitian ini adalah mengevaluasi pengaruh perbedaan suhu dan lama blansing dalam terhadap sifat fisikokimia dan morfologi granula tepung ubi kayu. Metode blansing menggunakan air panas bersuhu 50C, 55C dan 60℃ selama 5 menit, 7,5 menit dan 10 menit sebelum pegeringan dan penepungan. Hasil penelitian menunjukkan suhu dan lama pemanasan berpengaruh terhadap sifat fisikokimia tepung ubi kayu. Semakin tinggi suhu dan semakin lama pemanasan menyebabkan penurunan kadar air, kadar abu, kadar amilosa, meningkatkan kelarutan dan swelling power, serta menyebabkan perubahan morfologi granula atau butiran tepung. Effect of Temperature and Heating Time During Blanching Process on Physicochemical and Morfologi Properties of Cassava FlourProcessing of fresh cassava into flour is one alternative to overcome the physiological properties of cassava which has a relatively short shelf life. However, in general, traditionally processed cassava flour has several disadvantages such as low dough development, less acceptable texture and flavor when used as main material in bakery products, as well as other food products. Many efforts to improve the quality of cassava flour have been carried out, including the use of heat treatments. Hot water pretreatment has been reported to be beneficial for improving quality of dried horticulture commodities. The purpose of this study was to evaluate the effect of temperature and length of blanching on physicochemical properties of cassava flour. The method was carried out by blanching cassava chip in hot water at 50C, 55C and 60℃ for 5,7,5 and 10 minutes before drying and milling. The results showed the temperature and duration of heating affected the physicochemical properties and granular morphology of cassava flour. The higher the temperature and the longer the blanching cause a decrease in water content, ash content, amylose content, increase solubility, increase swelling power, and slightly changed the granular structures.

Abstract

Beras merupakan makanan utama orang Indonesia. Oleh sebab itu produksi beras yang bermutu sangat penting untuk memenuhi asupan gizi masyarakat. Berdasarkan hasil penelitian yang berjudul pengaruh perkecambahan terhadap peningkatan mutu beras, bahwa perkecambahan gabah sebelum digiling menjadi beras dapat meningkatkan nilai gizi beras. Namun belum diketahui efek dari perkecambahan gabah terhadap rendemen, kualitas fisik dan nilai sensori beras. Tujuan penelitian ini adalah untuk mengetahui pengaruh perkecambahan gabah terhadap rendemen, kualitas fisik (persentase beras kepala, beras patah, dan beras menir) dan nilai sensori (warna, aroma, rasa, dan tekstur) nasi dari beras yang dihasilkan. Penelitian ini menggunakan rancangan acak lengkap satu faktorial. Apabila data hasil analisis statistik berbeda nyata maka akan dilanjutkan dengan uji lanjut Duncan. Hasil penelitian menunjukkan bahwa rendemen beras setelah dikecambahkan mengalami penurunan. Panjang kecambah berpengaruh sangat nyata pada taraf 1% terhadap kualitas fisik beras seperti persentase beras kepala, beras patah dan beras menir, dan berpengaruh nyata pada taraf 5% terhadap parameter warna dan rasa nasi. Kesimpulan hasil penelitian adalah semakin panjang kecambah gabah, maka rendemen, kualitas fisik dan nilai sensori beras cenderung menurun. The Effect of Grain Germination on Yield, Physical Quality, and Rice Sensory ValueRice is the main food for Indonesians. Therefore the quality of rice production is very important to fulfill the nutritional intake of the community. Based on the results of research cited about effect of germinatioan to improve rice quality that germination of grain before milling into rice can increase the nutritional value of rice. However, the effect of grain germination is unknown on the yield, physical quality and sensory value of rice. The purpose of this study was to determine the effect of grain germination on the yield, physical quality (percentage of head, broken, and groats of rice) and rice sensory (colour, flavour, taste, and texture) value of rice produced. This research uses a completely factorial completely randomized design. If the results of the statistical analysis differ significantly, it will be continued with Duncan tests. The results showed that the yield of rice after germination had decreased. Sprout length has a very significant effect on the level of 1% on the physical quality of rice such as percentage of head, broken, and groats of rice and has a significant effect on the level of 5% on the colour and flavour parameters of rice. The conclusion of the research is the longer the grain sprouts, the yield, physical quality and sensory value of rice tends to decrease.

Abstract

Ketepeng cina Senna alata L. is one of the plant species growing in the tropical climate whose leaves have various bioactive components. It has been used as a traditional medicine to treat skin diseases. Ketepeng cina has been cultivated in several regions in Indonesia and the results are exported abroad to be used as medicinal raw materials. So far, the plant extraction process is still using the maceration method. This method is simple but has weaknesses in time consumption making it less efficient. The extraction method by ultrasonic waves promises more efficient extraction process than the maceration method. The purpose of this study was to determine the differences in extraction techniques and solvent concentration on the concentration of phytochemical constituents in ketepang cina leaves. The research design used a completely randomized design with two factorial patterns. The first factor was the technique of extracting Ketepeng cina leaves (maceration, ultrasonication), and the second factor was the concentration of solvent/ethanol (40%, 70%, 96%) The observation parameters included analysis of the content of total phenolic compounds, flavonoids, and tannins. The results showed that the use of the ultrasonication technique provided efficiency in extraction time compared to the maceration technique. The use of 70% ethanol resulted in higher concentrations of total phenolic and flavonoid compounds (28,17 mgGA/g) and (17,61 mgQE/g), but the highest concentration of tannins produced by 96% ethanol solvent was 6,78 mgAT/g.

Abstract

Mangga (Mangifera indica, L.) cv. Gedong merupakan salah satu kultivar unggulan Jawa Barat,dengan daya saing tinggi di pasar domestik dan internasional. Sulitnya mendapatkan kematangan serempak merupakan tantangan yang harus diatasi dengan teknologi pascapanen yang tepat. Penggunaan karbit sebagai pemacu kematangan buah tidak lagi dianjurkan dan perlu diganti dengan bahan lainya seperti etilen. Penelitian ini bertujuan untuk mendapatkan konsentrasi gas etilen dan lama paparan serta kondisi pemeraman terbaik untuk menghasilkan buah mangga Gedong matang sempurna dengan mutu yang baik.   Penelitian dilakukan dengan Rancangan Acak Lengkap Faktorial. Perlakuan yang diterapkan adalah konsentrasi gas etilen (0, 30, 60 dan 90 ppm) selama 24 jam pada kondisi ambient dan dalam ruangan berpendingin (AC).   Hasil penelitian  menunjukkan bahwa,  perlakuan  terbaik  untuk  mendapatkan  mangga  cv.  Gedong matang sempurna dengan mutu yang baik yaitu penggunaan etilen 30 ppm. Dengan perlakuan tersebut kematangan buah mangga tercapai 2 hari pada suhu berpendingin dan 4 hari   pada kondisi ambient  lebih cepat dibandingkan mangga tanpa paparan gas etilen. Suhu ruangan pemeraman lebih berpengaruh terhadap mutu buah mangga Gedong matang yang dihasilkan. Pemeraman dengan gas etilen meningkatkan kadar TPT (89,55%), vitamin C (71,31%), dan total fenol (167,23%) serta menurunkan total asam (92,62%) dan  total flavonoid (71,67%) dari buah mangga Gedong matang.  Konsentrasi gas etilen tidak berpengaruh terhadap kadar air, TPT, total asam dan vitamin C pada buah mangga Gedong matang hasil pemeraman. Gas etilen tidak menyebabkan penurunan mutu berdasarkan parameter fisikokimia yang diamati. Ripening of Mango (Mangifera Indika L.) CV. Gedong Using Ethylene GasMango (Mangifera indica, L.) CV. Gedong is one of the leading cultivars in West Java, with high competitiveness in the domestic and international markets. The difficulty of obtaining simultaneous ripe fruits is a challenge that must be overcome with the right postharvest technology. The use of carbide as a ripening booster is no longer recommended and needs to be replaced with ethylene gas which has been practiced internationally. This study aims to obtain the best ethylene gas concentration and exposure time and ripening conditions to produce perfectly  ripe  Gedong  mangoes  with  good  quality.  The  research  was  conducted  with  a completely randomized factorial design. The treatment applied was the concentration of ethylene gas (0, 30, 60 and 90 ppm) for 24 hours in ambient conditions and in an air conditioned room. The results showed that, the concentration of 30 ppm ethylene gas was the best treatment to produce fully ripe mangos with good quality, where maturity was obtained 2 days (air-conditioned room) to 4 (ambient condition) days earlier compared to those without ethylene gas exposure. The temperature of the ripening room has more effect on the quality of the ripe Gedong mango produced. Ripening with ethylene gas increased levels of TPT (89.55%), vitamin C (71.31%), and total phenols (167,23%) and decreased total acid (92.62%) and total flavonoids (71.67%) from ripe Gedong mangoes. Ethylene gas concentration had no effect on water content, TPT total acid and vitamin C in ripened mango Gedong. Ethylene gas did not cause deterioration based on observed physicochemical parameters.

Abstract

Black Soldier Fly (BSF) farming showed an increasing trend in the past 5 years. The production process generates a leftover, that is the exuviae which are still untapped. BSF exuviae contain chitin and chitosan which can be utilized in various fields, one of which is fruit preservatives. Grapes (Vitis vinifera) is known to have many benefits and has a content of vitamins A, B, C, and E but it has a short shelf life. The purpose of this study was to characterize chitosan from BSF exuviae and choose the best edible coating method to be applied to grapes to prolong the grape’s storage time. Characterization includes physical condition, percent solubility, degree of deacetylation, and yield of the chitosan. Then, edible coating tests were carried out with 2% acetic acid solvent followed by two different methods, namely dyeing method with 5, 10 and, 15 minutes immersion time and spray method with a chitosan solution concentration of 0,5%, 1%, 1,5%, 2 %, and 2,5%. The results showed that chitosan extracted from BSF exuviae produced a physical appearance in the form of white brown powder with 55% solubility and a degree of deacetylation of 91,88%. The chitin yield is 16,2%, followed by the chitosan yield of 4,8%. The best edible coating method which can maintain the physical appearance of grapes and inhibiting fruit decayed was obtained by dipping method at a concentration of 2,5% for 10 minutes. Based on the overall observations, however, the results obtained from the dip and spray method were not significantly different.
