Abstract

Crackers is one of the popular food products among the people of Indonesia. The addition of cassava leaves into crackers take advantage of the availability of cassava leaves, especially during harvesting. The research aims to determine some parameters of drying characteristics of vegetable crackers. Drying crackers were conducted using sun drying and rack dryers with the temperature of 50 °C and crackers’s thickness of 2 mm, 3 mm, and 4 mm. The results showed that drying using dryer with cracker’s thickness of 2 mm, 3 mm, and 4 mm spent a drying time about 3.5-4.5 hours that was faster than sun drying around 4.5 – 5.5 hours. The decrease of moisture content in the dryer was quicker than sun drying. The final moisture content of cracker using dryer had average value of 8.28% which was lower than the sun drying of 12.95% . The color changes that occured after the drying process using dryer and sun drying produced value <0.5 which had a meaningless or unchanged after the drying process. Depreciation of material diameter on dryers had a value of 11.92% which was greater than sun drying. The mean of moisture balance (Me) in the dryer of 7.348 %bb was lower than using sun drying. Drying constant of creackers value using dryer had an average value of 1.196 /hours that was higher than the sun drying 0.84 /hour.

Abstract

Digester biogas rumah tangga berpotensi menyediakan bahan bakar terbarukan pengganti LPG (liquefied petroleum gas). Penelitian ini bertujuan untuk merancang-bangun dan menguji kinerja digester biogas rumah tangga tipe tangki mengapung (floating tank) dengan substrat kotoran sapi. Penelitian dilakukan dengan membuat digester biogas tipe floating tank menggunakan sumur dangkal dari pasangan bata semen yang diplester (diameter-dalam 139 cm, kedalaman efektif 140 cm) sebagai digester dan tangki air kapasitas 2000 l sebagai penampung biogas. Ukuran digester didasarkan pada kebutuhan biogas untuk keperluan memasak rumah tangga dan potensi kotoran empat ekor sapi. Kinerja digester dievaluasi dari produksi biogas, komposisi biogas, dan kemampuan digester dalam mendekomposisi substrat yang dinilai dari penurunan kandungan padatan tak stabil (volatile solid, VS). Hasil penelitian menunjukkan bahwa pada suhu lingkungan rata-rata antara 26,97 ℃ (pagi) dan 31,97 ℃ (sore) digester bekerja pada pH rata-rata 7,7 dengan dekomposisi VS mencapai 56,3%. Dengan laju pengumpanan kotoran sapi cair 60 l/hari, produksi biogas dapat mencapai 1.300 l/hari dan produktivitas biogas mencapai 634,6 l/m3 volume aktif digester. Biogas yang dihasilkan memiliki kualitas medium dengan kandungan metana (CH4) mencapai 50,28% dan nilai kalori 18,01 MJ/Nm3. Lumpur digestat berpotensi sebagai pupuk organik dengan kandungan hara N 4,55%; P 2,16%; dan K 3,89%. Salah satu keunggulan yang sangat menonjol dari digester floating tank adalah desain yang sederhana, biaya terjangkau, dan diperkirakan akan awet, sehingga dapat dijadikan sebagai model untuk dikembangkan dan diadopsi.

Abstract

The taste of crackers can be varied by mixing two or more raw materials. Crackers can be made from a mixture of melinjo flour and cassava (gaplek) flour. The purpose of this study is to know and indentify the physical characteristics of crackers made from a mixture of melinjo flour and geplek flour.This study used a completely randomized design (CRD) with 6 different treatments, these are the mixture of melinjo flour and gaplek flour P1(100%, 0%), P2 (80%, 20%), P3 (60%, 40%), P4 ( 40%,60%), (20%,80%), P6(0%,100%). This study uses several parameters to be measured such a hardness, density, color, taste, and crispness. The result of this study showed that the hardness of each treatment is relatively the same. The density of crackers showed that the higher the melinjo flour content, the higher the density. There was a change in the color of the crackers before and after they were fried. The results showed that the concentration of 20% melinjo flour and 80% cassava flour were the most preferred types of crackers by the panelists. Keywords: Crackers, Gaplek, Melinjo, Physical Characteristics And Mixture

Abstract

Based on the survey result of vegetable crop production in Indonesia, the national carrot harvest area is 13,398 hectares spread over 16 provinces.  Meanwhile, the average carrot production in Lampung Province can reach 16,02 tons/year with a harvested area of 369 hectares (BPS, 2018).  Damage to horticultura commodities can occur if the post-harvest handling is not done well.  Many problems were found related to the decay of agricultural products due to the development of microorganisms which caused gread losses for farmers. Sterilization with UV lamps is an attempt to kill and eliminate pathogens or spoilage microbes that cause food spoilage. This sterilization aims to determine the effect of UV-C rays on the quality of carrot during storage. This research was conducted using a completely randomized design (CRD) with 2 factors, namely the irradiation distance factor (20 cm, 40 cm, and 60 cm) and the irradiation time (1-, 20, and 30 minutes). The data obtained were analyzed by ANOVA test. In the 60 cm irradiation distance treatment with an irradiation time of 30 minutes is the recommended storage distance because it can suppress root growth with an average value of 16,67 %, physical damage 14,58%, and gives the panelists the best assessment of the freshness level parameter with an average value of 3,24 (scale 5), texture with an average value of 3,25 (scale 5), and skin appearance with an average value of 3,15 (scale 5). Keywords: Carrots, Microbes, Influence, UV-C Rays, Radiation

Abstract

Eggs are one of the sources of protein, fat, minerals, and vitamins that are good for the body. Eggs are prone to deterioration in quality caused by physical damage in the form of cracks that can occur during packing, transportation, and storage. One way to prevent damage is by the salting method. Therefore, it is necessary to soak in a salt solution to become salted eggs. The purpose of this study was to determine the effect of the level of salt concentration and temperature during the immersion of eggs in a salt solution to obtain quality salted eggs. The temperatures used in this research of 50ᵒC, 55ᵒC, 60ᵒC, and 65ᵒC, and salt concentrations of 15%, 20%, and 25%. The parameters observed were the measurement of the salt concentration of the salted egg, the changing color in the salted egg yolk, and the taste test for the saltiness of the salted egg. The results obtained by soaking salted chicken eggs at 60ᵒC at a concentration of the salt solution (15%, 20%, 25%) have met the SNI standard quality of 2% because the higher the concentration of salt solution given, the salt content in the egg will also increase. The taste level of saltiness in salted egg chicken obtained an average score of 3 with the taste of egg with salty egg, in which the salt solution increases according to temperature and concentration. The color of the eggs produced at 60ᵒC and 65ᵒC changed from normal yellow to orange-colored yolk eggs. The increase in temperature and the concentration of different salt solutions on the salted egg yolk color is affected by diffusion currents, and It causes the taste of the salted egg to turn salty. Keywords: Chicken Salt Eggs, Salt Solution, Soaking.

Abstract

Papaya is one of the fruits that are liked in the community because of it has a sweet taste and rich in vitamin C. In Indonesia papaya is abundant and the price of it is relatively low so that papaya gets wasted easily.  Therefore, it is necessary to process the product to extend the shelf life and increase the value-added papaya fruit. Papaya flour is a product  of  new  innovations  of  flour  from  the  fruit  besides  papaya  flour  is  food processed products to increase the value-added agricultural produce. In this study used the temperature treatment and type of papaya,  with successive research procedures namely taking papaya fruit, peeling, slicing, soaking, drying, grinding, and sieving. The results showed that the temperature of drying can affect the moisture content of papaya flour, color, aroma, and vitamin C. The best quality of papaya flour is at 70°c, which is 23 with the desired color and aroma, resulting in an average water content of 4.9678% and vitamin C content that tends to be higher with a value of 420, 0667 (mg/100g). Drying with papaya type treatment does not significantly affect the moisture content of flour, color, aroma and vitamin C content. Keywords: Aroma, Drying, Flour, Papaya, Vitamin C

Abstract

The feed given to goats is generally in the form of grass and cocoa pods. The grass that is given directly without being chopped is not eaten as a whole by the goat, but what is chopped first is eaten until it runs out. This service program aims to apply a forage chopper machine for goats at Isbani Farm so that the forage becomes fine in size. The method for reducing or smoothing the size of forage is to use a chopper in the chopping process. This chopper is in the form of two blades mounted on the axle and driven by diesel so that it can rotate and chop forage material. Service activities include problem formulation with partners, preparation of chopper machines, training on the use of chopping machines for partners and program evaluation. Partners are very open in conveying problems and very cooperative in coordinating. The animal feed material chopper machine can be well prepared; covering frame; the chopper and the driving motor. The training and application of the counting machine to partners went well; partners can absorb the knowledge and skills provided by the community service team. Evaluation of the service program went well; partners' knowledge increased by about 45%. It is necessary to conduct training in making silage or durable feed from agricultural waste feed ingredients such as corn stalks, rice straw and cassava leaves. It is necessary to create a sustainable program so that the partner assistance process is sustainable.
