Penerapan Budidaya Sayuran Vertikultur sebagai Optimalisasi Lahan di Perumahan Griya Pertiwi Kota Metro

ABSTRAK Konsep perumahan saat ini banyak yang mendesain rumah dengan lahan pekarangan yang sempit, sedangkan banyak program pemerintah yang mengacu pada pemenuhan kebutuhan pangan melalui optimalisasi pemanfaatan lahan pekarangan. Perumahan Griya Pertiwi Kota Metro juga memiliki lahan pekarangan yang sempit. Untuk meningkatkan optimalisasi lahan pekarangan warga Griya Pertiwi maka sistem budidaya yang cocok adalah budidaya vertikultur. Metode yang digunakan dalam program pengabdian ini adalah sosialisasi dan pelatihan budidaya sistem vertikultur pada warga perumahan Griya Pertiwi yang memiliki lahan pekarangan sempit. Materi sosialisasi ini terdiri dari 3 bahasan : 1) kajian teknologi vertikultur sebagai solusi manajemen keuangan rumah tangga, 2) perakitan alat/media vertikultur serta 3) penanaman dan pemeliharaan tanaman pada sistem vertikultur. Setelah proses sosialisasi dan pelatihan budidaya sistem vertikultur ini, warga perumahan Griya Pertiwi sangat antusias. Warga menerapkan budidaya sistem vertikultur ini di pekarangan rumahnya, sehingga dapat memenuhi kebutuhan pangan yang sehat dan higienis bagi keluarganya. Kata kunci : lahan perumahan, vertikultur, kebutuhan pangan keluarga.ABSTRACTCurrently, many housing concepts are designing with narrow yards, while many government program refer to fulfill food for family through optimizing the use of yard land. Griya Pertiwi housing in Metro City also has a narrow yard. To increase the optimization of the homesteads of Griya Pertiwi resident, a suitable cultivation system is verticulture cultivation.The method in this program is socialization and training of verticulture cultivation for residents of Griya Pertiwi housing who have narrow yard. The socialization material consist of 3 topics : 1) study of verticulture technology as a household financial management solution, 2) assembling verticulture tools/media and 3) Palnting and maintaining plants in verticulture system. After socialization and training on cultivation of verticulture system, the residents of Griya Pertiwi were very enthusiastic. They apply this verticulture cultivation system in their yards, so that they can fulfill healthy and hygienic food for their families.Keywords: Housing yard, verticulture, daily food fulfil

PEMANFAATAN SERABUT KELAPA DALAM MENINGKATKAN KUALITAS PUPUK ORGANIK DARI AMPAS TAHU

Organic fertilizer production with the use of coconut fiber to improve the quality of organic fertilizer has been done. This study aims to determine the increase in the quality of organic fertilizer pulp by utilizing coconut fibers in increasing the porosity of raw materials. Utilizing combination EM4 bioindicator and Starbio bioindicator to improve the process of decomposition of organic matter are applied in this research. This research use experiment method by comparing the quality of the fertilizer from tofu dregs only with the quality of the fertilizer tofu dregs that is adding by massa variations of coconut fibers. Bioindikator combination of EM4 and starbio also studied in this research. The result of this research showed that by using 7.5 grams of coconut fibers can increase the organic matter decomposition process. Combination of EM4 bioindicator and Stabio bioindicator also can increase decomposition process so the percentage of organic material in the organic fertilizer are on the threshold by SNI, namely 54,72%.Kata Kunci: ampas tahu, fermentasi, pupuk, serabut kelap

ANALISIS NILAI GIZI HASIL FERMENTASI LARUTAN GULA AREN MENGGUNAKAN TERATAI SALJU (Saussurea involucrata)

The nutrition level of fermented palm sugar solution using snow lotus (Saussurea involucrata) has been analyzed. It is necessary to determine it before this product is consumed by public. Palm sugar solution had been fermented using snow lotus (Saussurea involucrata) for 72 hour. The palm sugar solution before and after fermentation was analyzed its nutrition level such as protein, carbohydrates, vitamin C and alcohol level (methanol and ethanol) based on MUI and BPOM. After fermentation the level of protein, carbohydrates, vitamin C with consecutive is 0.557%; 1.81 mg/kg and 5.71 mg/kg. The level of protein content increased by 55 % and 42 % for carbohydrates, but the level of vitamin C decreased 16% when it compared to palm sugar solution before fermentation. Methanol wasn’t detected in fermented product after 72 hour, while ethanol is still below the threshold set by the MUI and Badan POM is 0.8%, so it is safe for consumption.

The Management of Vegetable Cultivation to Protect the Consumer from Heavy Metal Pollution

Since heavy metals are potentially accumulated within vegetable organs, this research is conducted to identify those metals and their effects on the nutrient content. Two-Ways Analysis of Variance determined the effect of various location, vegetables, and vegetable organs towards metals. One-Way Analysis of Variance determined the effect of locations and fruit type on metals uptake. It is followed by examining heavy metals accumulation within edible parts of vegetables and its effects on protein, vitamin A and C. The Randomized Group Design of 3 factors (media, distribution, and vegetable organs) is employed considering 3 different harvesting times harvesting and cultivation adjustment (trimmed or not trimmed). The 3 factors Covariant Analysis defined the influences of media, time and way of harvesting on protein, vitamin A and C of water kangkoong stem and leaves. The results showed a significant influence of various areas (paddy field, industrial area, and highland) on Cd, Cr and Pb uptake within stems, leaves and fruits. Generally, the period and way of harvesting significantly influence the heavy metals uptake, level of protein, vitamin A and C, Mg and chlorophyll of water kangkoong. It is suggested to prune and harvest vegetables earlier to minimize heavy metals uptake and nutrient degradation

PENGARUH VARIASI PERENDAMAN UDANG VANAME (Litopenaeus vannamei) DALAM ASAM BUAH ALAMI TERHADAP PENURUNAN KADAR TIMBAL (Pb) DI TAMBAK TRADISIONAL PASIR SAKTI LAMPUNG TIMUR

Natural fruit acids are fruits that taste sour containing organic acids, one of which is citric acid, examples of natural fruit acids are tamarind, lime, lemon, pineapple. Natural fruit acids can be used as an ingredient for soaking food derived from fishery products to get rid of the fishy smell and give the people a flavor of cooking. The purpose of this study was to determine the effect of immersion of natural fruit acids on the reduction of lead (Pb) levels in Vanamae shrimp, to determine which immersion variations had the most effect on reducing lead levels in Vanamae shrimp. This study used an experimental method with a completely randomized block design (RAKL). The experiment was carried out with 5 treatments, namely Control (200 grams of shrimp without immersion), Treatment 1 (200 grams of shrimp + 25ml filtrate), Treatment 2 (200 grams of shrimp + 25ml of lime), Treatment 3 (200 grams of shrimp + 25ml filtrate lemon), and treatment 4 (200 grams of shrimp + 25 ml filtrate), each treatment was given 4 times each. Based on the analysis of the anava test, the results obtained Fhit> Fdaf, It was concluded that there was an effect of immersion in natural fruit acids on reducing the levels of lead (Pb) in Vaname shrimp meat, soaking with lime acid was the most significant to reduce the levels of lead metal Pb

ANALISIS KADAR GIZI TANAMAN KANGKUNG PADA MEDIA TERCEMAR KROMIUM MELALUI PENGATURAN KADAR MAGNESIUM

Heavy metals pollution cannot be avoided since there is an industrial and technological advancement. They have great potential to contaminate soil and water in the environment, while soil and water are the growth medium for food crops. This research aims to analyze nutrient content of kangkoong that are grown on chromium-contaminated media by magnesium controlling method. This research uses the experimental method by controlling magnesium on chromium-contaminated media for kangkoong. Based on the results of this study, the magnesium controlling method on chromium-contaminated media can affect protein, vitamin A, and vitamin C levels. The interaction between chromium contamination with magnesium controlling method only has a significant effect on protein level but no significant effect on vitamin A and vitamin C. This has been proven statistically with a two-way ANOVA test with a significance value < 0,05. Kata kunci: kangkung,  logam kromium, protein, vitamin A, vitamin
