Abstract

Kacang tunggak sebagai salah satu kacang indigenous potensi untuk substitusi kedelai sebagai bahan dasar pembuatan tempe dan tahu. Sumber daya genetik kacang tunggak perlu ditingkatkan keragamannya sebagai sumber plasma nutfah untuk perakitan varietas unggul baru. Induksi mutasi iradiasi sinar gamma pada kacang tunggak diharapkan dapat meningkatkan keragaman. Penelitian dilaksanakan dengan iradiasi biji kacang tunggak genotipe KM-4 dengan dosis 0, 200, 400, 600 dan 800 Gy dan dianalisis untuk memperoleh LD50 dan dilakukan iradiasi kembali dengan dosis 0, LD50-100, LD50-50, LD50, LD50+50 dan LD50+100 Gy. Karakter yang diamati meliputi tinggi tanaman, lebar tajuk, panjang tangkai, panjang daun, lebar daaun, periode panen, panjang polong, jumlah biji/polong, berat biji/tanaman dan kandungan protein biji kacang tunggak. Hasil penelitian menunjukkan bahwa nilai LD50 tanaman kacang tunggak adalah 724,84 Gy, iradiasi sinar gamma pada dosis750 Gy menghasilkan keragaman tertinggi dan iradiasi sinar gamma tidak meningkatkan keragaman terhadap kandungan protein biji kacang tunggak.

Evaluation of Land Capability for Agroforestry Development in Ciliwung Watershed 1Rini Fitri, 2Nuraida, 3Eka Rahmi1Department of Agrotechnology, Faculty of Agriculture, Almuslim University,2Department of Agroindustrial Technology, Faculty of Agriculture, Almuslim University,3Department of Forestry, Faculty of Agriculture, Almuslim University,Jl. Almuslim Bireuen 24263, Aceh Indonesia*Corresponding author: rinnie_fitrie@yahoo.co.id Abstract Land conversion is one cause of damage to watersheds (DAS), leading to a complex problem physically, economically and socially in the upper and lower watershed. Upper Ciliwung watershed is classified as watershed of which its carrying capacity is restored as it has indicator qualification of high until very high and it is important to be handled. This study was aimed to analyze the cability of upper Ciliwung watershed area for the development of sustainable agroforestry. The units of land use (SPL) used for intensive observation were as many as 60 units of land use spread over seven (7) sub-watershed, namely sub-watershed of Cibalok, Cisuren, Ciliwung, Ciesek, Cisukabirus, Cisarua and Ciseseupan. The unit of land use of which its land capability class was analyzed included the use of shrub land, open land and dry land agriculture. The unit of land use will be used as a recommendation for the use of agroforestry in upper Ciliwung watershed. The results showed that the land capability class in the upper Ciliwung watershed consisted of land capability class II, covering an area of 329.7 ha (23.92%), capability class III of 464.8 ha (33.72%) and capability class IV of 584 ha (42.36%). Land use of upper Ciliwung watershed was dominated by class III with dominant obstacle factor namely bumpy slope. Analysis of land capability on shrubland, open land, and dry land agriculture which spread over the unit of land use in the area of upper Ciliwung watershed was generally recommended for land use of agroforestry-agrisilvopasture and agroforestry-agrisilviculture.Keywords: Land capability, land use, agroforestry, upper Ciliwung Watershed

Abstract

Kebijakan subsidi pupuk merupakan  salah satu kebijakan yang penting di bidang pertanian di Indonesia. Selain itu, kebijakan yang dilakukan oleh pemerintah kebijakan Harga Pembelian Pemerintah (HPP). Kebijakan ini bertujuan ntuk melindungi petani dari jatuhnya harga gabah pada saat panen raya. Tulisan ini mengkaji dampak kebijakan subsidi pupuk dan HPP bagi produsen dan konsumen. Data yang digunakan adalah data time series tahunan dari tahun 1981 sampai 2014 dengan model ekonometrika persamaan simultan. Hasilnya menunjukkan bahwa surplus produsen dan surplus konsumen dipengaruhi oleh kondisi pasar beras domestik. Surplus produsen akan dicapai jika pemerintah menerapkan kebijakan jaminan harga berupa peningkatan Harga Pembelian Pemerintah (HPP), sedangkan surplus konsumen akan dicapai jika pemerintah menerapkan kebijakan peningkatan subsidi input berupa kredit pertanian dan subsidi pupuk serta peningkatan produktivitas areal.  Untuk meningkatan surplus produsen dan konsumen secara merata maka perlu diterapkan paket kebijakan yang merupakan kombinasi dari kebijakan subsidi pupuk dan kebijakan HPP.

Abstract

The use of various types of active ingredients with high intensity pesticides in dealing with pest disturbances often makes farmers pay less attention to the negative impacts. Deltamethrin, sipermetrin, λ-cyhalothrin and chlorpyrifos are active ingredients of pesticides that are often used by cocoa farmers to control pests Helopeltis sp. spp. which is one of the main pests in cocoa plants. Field tests on pesticide application were carried out on cocoa plants with Helopeltis sp. spp. High. This test was carried out on 4 treatment blocks applied with different active ingredients. Pesticide residue testing was carried out on cocoa beans, before and after pesticide application using the QuEChERS method on GC-ECD. The results of pesticide residue testing showed that the use of λ-cyhalothrin pesticides did not leave pesticide residues, while sipermetrin pesticides left far fewer pesticide residues compared to deltamethrin and chlorpyrifos pesticides. The results of these pesticide residues are compared to the Pesticide Maximum Residual Limit (MRL) according to the European Commission Part A of Annex I to Reg. 396/2005, shows the results of λ-cyhalothrin and cipermethrin pesticide residues test under pesticide MRL, while the results of deltamethrin and chlorpyrifos pesticide residue test are above the specified pesticide MRL.

Abstract

ABSTRAKPenelitian ini dilakukan untuk mengetahui fungsi limbah las karbit yang selama ini hanya dibuang tanpa ada yang menghiraukan seolah menjadi sampah yang tidak berguna.  Penelitian ini  dilaksanakan pada bulan Maret sampai Juli 2018.  Penelitian dilaksanakan di Kebun Percobaan Fakultas Pertanian Universitas Muhammadiyah Jakarta yang berada pada ketinggian 25 m di atas permukaan laut (dpl).  Penelitian ini bertujuan untuk mengetahui pengaruh limbah las karbit terhadap pertumbuhan dan produksi cabai keriting.  Penelitian ini dilaksanakan dengan menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) dengan 4 perlakuan, yaitu P0 tanpa limbah las karbit (kontrol), P1 (100 g per tanaman), P2 (200 g per tanaman) dan P3 (300 g per tanaman). Pemberian limbah las karbit berpengaruh nyata terhadap parameter yang diamati P2 (200 g per tanaman) berpengaruh nyata terhadap tinggi tanaman umur 5 MST, jumlah cabang umur 6 MST, lingkar batang umur 5 MST. Pemberian limbah las karbit bisa memperbaiki pH tanah akan tetapi tidak bisa menyediakan unsur hara bagi tanaman walaupun limbah las karbit mengandung CaCO3 dan ZPT.ABSTRACTThis research was carried out to determine the function of carbide welding waste which had only been disposed of without being ignored as if it were useless waste. This research was conducted from March to July 2018. The research was conducted at the Experimental Garden of the Faculty of Agriculture, Muhammadiyah University, Jakarta, which was at an altitude of 25 m above sea level (asl). This study aims to determine the effect of carbide weld waste on the growth and production of curly chili. This study was carried out using a Randomized Complete Block Design (RCBD) with 4 treatments, namely P0 without carbide welding (control), P1 (100 g per plant), P2 (200 g per plant) and P3 (300 g per plant). Giving carbide welding wastes significantly affected the parameters observed P2 (200 g per plant) significantly affected plant age 5 WAP, number of branches aged 6 WAP, stem circumference age 5 WAP. Giving carbide welding waste can improve soil pH but cannot provide nutrients for plants even though carbide weld waste contains CaCO3 and growth regulator.

Abstract

Cultivation of edible mushrooms has been evaluated as an effective way for increasing income of people in developing countries. Pleurotus ostreatus, well known as an oyster mushroom is the most popular edible mushroom in Indonesia. They usually is cultivated using a sawdust as a main substrate. The aim of this research is to reveal the addition of coconut water, the byproduct of traditionally coconut process as an inducing substance in P. ostreatus cultivation.  The results shown that the addition 25% (v/v) of coconut water in substrate of P. ostreatus induce the growth of mycelium. On the other hand, the addition of 50% (v/v) of coconut water affect in the day of fruit body formation become faster as well as increase the number of pileus (stalk)  and  the weight of fruit body.
