Abstract

Development and development of the quality of farming communities in carrying out farming is one aspect that supports the creation of increased agricultural production and productivity, so that profits can be increased. Agricultural development, especially horticultural crops that have been implemented, has made a positive contribution to economic development. The clearer and more obvious that the economic system is, the more it is influenced by the agricultural sector. This sector has an impact on the sustainability of the income of farmers in an area.Cultivation of vegetable crops in Indonesia is generally carried out with monoculture and polyculture cropping patterns. Monoculture is a cultivation system in an area of land planted with only one type of plant. Meanwhile, polyculture is a system of plant cultivation in the same area of land in one year planted with several types of plants, both planted at the same time or slightly different times. The development of pests and diseases tends to occur more easily in monoculture cropping patterns because food sources for pests and pathogens are always available. On the other hand, a polyculture cropping pattern followed by a crop rotation pattern can break the life cycle of pests and diseases.Crop rotation has many advantages. In some organic crop cultivation systems, crop rotation is highly recommended. Some of the advantages of crop rotation are that it can reduce the intensity of pest or disease attacks, increase soil fertility, and crop rotation is highly recommended. Some of the advantages of crop rotation are that it reduces the intensity of pest or disease attacks, increases soil fertility, and is able to form a stable micro-ecosystem. In addition, in the agribusiness world, several types of commodities, especially vegetables, are able to meet the desired market demand.

Abstract

Karo regency is center for carrot (Daucus carota L.) production in North Sumatra. It is estimated more than 1% of the rejected carrot yields are produced in each planting period. With the predicted harvest area, more than 1,000 tons of rejected carrots will be produced annually. This potential can be used as the material for the manufacture of liquid organic fertilizer (LOF). There are three research variables that were carried out, namely: 1) Independent variables consisting of fermentation periode consisting of 10 days, 20 days, 30 days and 40 days. 2) Fixed variable consisting of 4 kg of rejected carrots, 5 liters of water, 5 liters of old coconut water, 0.6 liters of brown sugar water, 0.05 kg of yeast, 0.5 liters of EM-4. 3) Bond variables consist of C-Organic content, Phosphorus content, Potassium content  and Nitrogen and pH content. The results showed that the peak of microorganism activity occurred on the 30th day. This treatment obtained the highest proportions of 0.07%, 0.14%, 0.87%  for Nitrogen, Phosphorus and Potassium levels respectively. The highest C-Organic content was obtained in the H-20 and H-30 treatments with a proportion of 1.55%. The acidity level was stable at a value range of 3.5 from the start to the end of the quenching process. LOF carrots produced are still not in accordance with established quality standards. The percentage value of macro elements, C-Organic and pH is still below the set quality standards.

Abstract

Research has been carried out using Mabar Compost and NPK Yara Mila 16:16;16 on lettuce (Lactuca Sativa L.). The aim of the study was to determine the effect of Mabar Compost Fertilizer, the effect of NPK Yara Mila 16:16:16, and the effect of the interaction between the two types of fertilizer on the growth and yield of lettuce plants. The study used a factorial randomized block design consisting of two factors. Factor I: Dosage of Mabar Compost with the symbol "K", namely K0: 0 Control (without treatment), K1: 350 grams/plot, K2: 550 grams/plot, and K3: 750 grams/plot. Factor II: Dosage of NPK fertilizer with the symbol "P", namely P0: 0 Control (without treatment), P1: 18 grams/plot, P2: 24 grams/plot, P3: 30 grams/plot. The results showed that Mabar Compost Fertilizer and NPK Fertilizer had no significant effect on the height and number of leaves of lettuce plants. Mabar Compost Fertilizer had a significant effect on the yield weight of fresh lettuce plants. The average yield weight of plants affected by compost was K0 (109.4 gr), not significantly different from K1 (120.2gr) but significantly different from K2 (125.4 gr) and K3 (165.2 gr). No interaction was found between the type of fertilizer and the dose of fertilizer on the research parameters.

Abstract

The next step after designing the composter is to test the performance of the composter. It is very important to observe the composting process find out the optimum type of composter to use both in the rate of composting and the compost produced. The aims of this research was to compare aerobic and anaerobic composters on composting rates and the compost. The method used was quasi-experimental by comparing the performance of the composter both in terms of composting speed, temperature, humidity, degree of acidity, color and smell of the compost. The results showed that anaerobic composting had a better rate (12 days) than the aerobic method (25 days). The composting process using an aerobic composter required a slightly higher temperature (36oC) than an anaerobic composter (32.5oC). The composting process using an aerobic composter has an average humidity value of 60.75 while that of an anaerobic composter is 68.54. Anaerobic composter showed almost the same value as the aerobic method for the degree of acidity. In terms of odor and color measurements, anaerobic composters produced a more pungent odor and a blackish brown color.

Abstract

Maggot memanfaatkan limbah organik sebagai sumber makanan, kemampuan maggot dalam mengurai sampah organik terkait dengan kandungan beberapa bakteri yang terdapat pada saluran pencernaan. Lalat jenis Black Soldier Fly mempunyai ukuran lebih besar dari lalat lainnya dan lalat jenis ini tidak menimbulkan penyakit karena masa hidupnya hanya untuk kawin dan bereproduksi. Upaya untuk meningkatkan kualitas pakan juga dipengaruhi adanya sumber protein hewani. Pakan yang belakangan ini cukup populer sebagai sumber protein hewani yang tinggi protein dan harganya terjangkau yaitu maggot BSF. Tujuan penelitian ini adalah untuk mengetahui media sampah organik seperti sabut kelapa muda, sampah restoran, kotoran ayam dan kotoran puyuh yang dapat meningkatkan kualitas pupuk organik dengan bantuan larva maggot BSF. Penelitian menggunakan metode Rancangan Acak Lengkap (RAL) non faktorial dengan pemberian variasi jenis campuran bahan organik dan beberapa perlakuan bahan organik kepada larva BSF. Hasil penelitian menunjukan, bahwa pemberian maggot dengan sabut kelapa muda tanpa dicampur dengan sampah organik sangat berpengaruh nyata terhadap laju pertumbuhan biomassa awal terhadap biomassa akhir maggot dari pakan yang dikonsumsi, menentukan bobot maggot yang paling maksimal dan mengetahui konsumsi substrat. Pemberian magot dengan sabut kelapa muda pada perlakuan SKM 1 berpengaruh nyata terhadap kadar C organik frass yang dihasilkan, yaitu sebesar 40,71% dan pada prameter C/N perlakuan SKM 1 (sabut kelapa muda + Larva maggot) menunjukan hasil yang nyata sebesar 74,54%. Akan tetapi pemberian sabut kelapa muda pada perlakuan SKM 1 tidak berpengaruh nyata terhadap biomassa akhir maggot, dikarenakan perlakuan pada SKM 1 menghasilkan lebih sedikit frass, lebih banyak residu kasar dan juga menyebabkan larva berukuran kecil dan kurus yang menunjukan larva tersebut tidak mampu mendegradasi sabut kelapa dengan baik, hal ini disababkan karena sabut kelapa muda mengandung selulosa (32%), lignin (38%), dan hemiselulosa (0,25%) sehingga susah dicerna oleh larva BSF.
