Abstract

Mosquito repellent are drugs used to repel or kill mosquitoes. Eco-friendly mosquito repellent or vegetable mosquito repellent can be made from various types of vegetable raw materials that contain mosquito-killer / repellent compounds such as cassava stem powder waste and citronella.  This cassava stem waste is very potential to be used because it is being one of the environmental problems in Indonesia. This research aims to establish the formation of mosquito repellent made from cassava stem powder and citronella, determine the suitability of quality based on the specifications of mosquito coils produced against SII No.1113-84 and organoleptic testing of mosquito coils. This research was conducted using a completely randomized design (CRD) with five treatments and three replications. The experiment consisted of 5 levels of mixed composition, namely 30% cassava stalks: 70% citronella (P1), 40% cassava stalks 60% lemongrass fragrant (P2), 50% cassava stalks: 50% citronella (P3), 60% cassava stalks.  40% citronella (P4), and 70% cassava stalks: 30% lemongrass (P5). The results showed that the mosquito repellent formed had a circle dimension of 81 cm, a diameter of 12 cm, a light brown color, a width of 7 mm, and a thickness of 4 mm. The quality of mosquito repellent based on the specifications is as follows: the moisture content range from 5.36 - 9.41% which fulfill the 80% quality standard, the burning time range from 3 - 4 hours, and the weight per seed range from 9.35 - 9, 77 grams. Judging from the quality based on these specifications, the mosquito repellent that is made does not fulfill the quality based on the specifications and quality requirements of SII. However, the mosquito repellent made is suitable for use as natural mosquito repellent because it is close to SII. Meanwhile, based on the organoleptic test with aroma parameters, the best natural mosquito repellent are treatment 1, formed by a mixture of 30% cassava stalks and 70% citronella.  Panelists gave an average score of 4.7 with the criteria being fragrant to very fragrant. Keywods: Cassava Stem Powder, Citronella Powder, Mosquito Repellent.

Abstract

Preparation of cassava seeds is usually done manually so it takes a relatively long time. TEP-1 type cassava stem cutter (Petokong) is a solution to meet the needs of cassava seeds in large quantities and quickly. This study aims to determine the performance of TEP-1 type Petokong and to compare it with manual cutting using a machete and saw, as well as to find out the cuttings of the seeds produced. The research was conducted in May 2019, at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The research was conducted by cutting cassava seeds using 3 different cutting tools, namely machetes, saws and TEP-1 type petokong. The research parameters consisted of cutting capacity, seedling size uniformity, seedling damage and growth test. The results showed that the highest cutting capacity of cassava stems was TEP-1 type petokong which produced 9720 seeds/hour while cutting using a saw produced 3600 seeds/hour and the lowest was cutting using a machete, as many as 1800 seeds/hour. The uniformity of cassava seeds cut using a TEP-1 type petokong is 99%, while cutting using a saw is 95%, and using a machete is 40%. The lowest percentage of damage to seedlings resulting from cutting was using TEP-1 type petokong which was 2%, damage to seedlings using saw was 10%, and using machetes was 20%. The results of testing the growth of seedlings up to the roots explained that cutting using a TEP-1 type of petokong had perfect and spreading root growth, cutting with a saw showed uneven root growth and cutting using a machete the root growth only occurred on several sides of the cassava seedlings. Keywords: Capacity, Cassava Stems, Cutting Tools.

Abstract

Sirsak merupakan buah yang cukup bernilai ekonomis, namun merupakan buah yang mudah busuk dan mudah rusak sehingga dapat mengakibatkan turunnya nilai jual buah sirsak. Karena buah sirsak mudah rusak, pengelolaan pascapanen yang buruk dapat mengakibatkan kehilangan hasil yang signifikan. Buah sirsak yang matang memiliki umur simpan hanya 2-3 hari. Karena umur simpan buah sirsak relatif terbatas, diperlukan diversifikasi produk dari buah sirsak, seperti mengolaj sirsak menjadi keripik. Pada umumnya penggorengan standar tidak bisa digunakan untuk membuat keripik sirsak. Namun, seiring dengan peningkatan teknologi, penggorengan vakum memungkinkan produksi keripik sirsak. Penelitian ini menggunakan rancangan acak lengkap faktorial dengan dua variabel yaitu suhu penggorengan faktor I (75, 80, dan 85 °C) dan tekanan penggorengan faktor II (-65, -68, dan -71 cmHg). Data yang diperoleh dianalisis, dilanjutkan dengan uji organoleptik dan pembobotan parameter. Parameter yang dianalisa adalah kadar air, susut bobot, lama waktu penggorengan, sedangkan untuk uji organoleptik dilakukan terhadap warna, rasa, kerenyahan dan aroma. Hasil penelitian menunjukkan bahwa pengaruh suhu dan tekanan penggorengan vakum terhadap mutu keripik sirsak berpengaruh sangat nyata terhadap kadar air, susut bobot, lama waktu penggorengan, dan uji organoleptik terhadap warna, kerenyahan, rasa dan aroma. Nilai Kadar air berkisar 4,33 – 7,44% susut bobot berkisar antara 69,33 – 75,16% dan lama waktu penggorengan berkisar antara 39 – 49 menit. Soursop is a fruit that is quite economically valuable, but soursop is included in perishable fruit, where the fruit is easily damaged which can lead to a decrease in its selling value of soursop fruit. The perishable nature of soursop fruit can result in high yield losses if not properly handled post-harvest. Ripe soursop fruit can only last for 2-3 days. The short shelf life of soursop causes the need for product diversification from soursop fruit. Generally, soursop chips cannot be made using conventional frying. However, as technology advances using vacuum frying, processing soursop into chips makes it possible. The study used a factorial completely randomized design consisting of two factors, namely factor I frying temperature consisting of 75, 80, and 85 and factor II frying pressure consisting of 65, 68, and -71 cmHg. The data obtained were analyzed, followed by organoleptic tests and parameter weighting. Parameters analyzed were moisture content, weight loss, and length of frying time, while organoleptic tests were carried out on color, taste, crispness, and aroma. frying time, and organoleptic test for color, crispness, taste, and aroma. The water content value ranged from 4.33 to 7.44%, the weight loss ranged from 69.33 to 75.16%, and the frying time ranged from 39 to 49 minutes.

Abstract

Indonesia has a diverse range of fish species in both seawater and freshwater. Lampung is one of the provinces in Indonesia that has a rich diversity of fish species. Lampung has a wide variety of fish species, including tilapia. Tilapia is a food material that decomposes quickly due to bacteria and microorganisms. As a result, one of them is the need for profitable handling by utilizing smoking technology. Smoked fish is popular in Lampung, but the most commonly used fuel is coconut shell, coconut coir, and corn cobs. The use of common fuel in the community still cannot assess the smoking fuel that can produce good quality standards of fish. As a result of the aforementioned issues, the research was to evaluate effect of fuel quantity and type on the quality of smoked fish. The goal of this study is to determine the effect of fuel amount on tilapia smoking, the type of fuel that can produce smoked fish of optimal quality, and the cost of fuel needed for tilapia smoking using coconut shell fuel, coconut coir, and corn cobs. The method used in this study was organoleptic testing on 25 panelists using a smoked fish score sheet determined by SNI smoked fish, and then the panelists' scores were processed using excel. The amount of fuel used and the duration of smoking have no effect on the quality value of smoked fish, and the type of fuel that can produce smoked fish of optimal quality, namely coconut coir, passed the SME (export quality certificate)  standard with an organoleptic value of smoked fish of 8.0.

Abstract

Biomass from oil palm fronds has not been effectively utilized in Central Lampung, there is a need for alternative processing of palm oil fronds into more useful materials. One method of processing palm fronds is to create bio charcoal briquettes, which are used as an alternative fuel. The purpose of this research was to see how palm fronds and particle size of palm oil fronds affected the properties of bio charcoal briquettes. The factorial completely randomized design (CRD) was used in the research with one factor, namely the particle size of the oil palm fronds passing through the sieve with one treatment, namely 20 mesh. To produce 25 experimental units, the study used five treatments with five replications. The obtained material was then tested for LSD. The results revealed that palm fronds had no impact on briquette density, moisture content, compressive strength, shatter resistance index, or rate of burning. The particle size of palm leaves going through the 20 mesh sieve affects density, compressive strength, shatter resistance index, and burning rate significantly. The findings revealed the following features of bio charcoal briquettes: The moisture content is 5.17-6.89%, the heating value is 4372.42 - 5074.50 cal/g a density of 0.568-0.674 g/cm3, a compressive strength of 3.85 - 4.58 kg/cm2, a shatter resistance index of 12.58-17.19%, a burning rate of 1.40-1.47 gram/minute, and a bottom temperature of 287°C. (for 60 minutes and a mass of 200 grams).
