Intisari Penelitian tentang kajian kandungan mineral dan asam sianida umbi gadung (Dioscore hispida Dennst) dilaksanakan di Kelurahan Wiladeg, Kecamatan Karangmojo, Kabupaten Gunungkidul mulai bulan September 2013 sampai dengan Maret 2014. Penelitian ini dilaksanakan dengan metode destruktif sampel tanaman yang berasal dari umbi gadung umur 6, 8, 10, dan 12 bulan, kemudian dianalisis di laboratorium untuk memperoleh data kandungan mineral yaitu kalsium, fosfor dan zat besi serta asam sianida. Data yang diperoleh kemudian dianalisis menggunakan Regresi linier dengan rumus Y = a + bX. Hasil penelitian menunjukkan bahwa kandungan mineral kalsium dan fosfor meningkat dengan bertambahnya umur panen, sedangkan kandungan asam sianida menurun dengan bertambahnya umur panen. Kata kunci: umbi gadung, asam sianida, mineral

Dengue shock system (DSS) is disease that is caused by virus and attacks the thrombosis of human being that may break the blood vessel and may cause death. This disease is caused by mosquito named Aedes aegypty whose cycle is five years and its proliferation is very quicklyÂ Â Â Â (7 days). Preventive efforts that have been done so far is by relying on chemical medicines by fogging and the use of Abate in which it may cause dependency on it and residue of mosquitoes. The content of Abate that kills mosquito larva is themephose, that is a compound organic phosphate which is the same as papain from papaya (Carica papaya L). TheÂ content of this compound kills the growth of mosquito larva by slowing down the rate of metabolism in their bodies. The content of compound in Ciplukan (Physalis angulata L) plants is chosen because it does not contain residue on the environments and, on the contrary, if is unintentionally drunk by people will minimize the effect of suffering from diabetes. This research used Ciplukan (Physalis angulata L) plant extract, particularly from its leaves and stems because its content of alkaloid is more than the content of themephose in Abate; that is 4.06 ppm and 1,56 ppm per 100 gram of the plant (Abate 1 ppm per 100 gram), so in term of activity it is proven that by using the leave extract can kill the mosquito larva in shorter time, less than 24 hours with concentration 100%. Meanwhile, in the stem solution, the percentage of the death of larva is almost the same as the papaya solution, in which it takes less than 78 hours with concentration 100%. It was supported by the result of test using CRD from which it was known that leave extract has larger coefficient than stem extract. It means that the capability of the leave extract (deviation standard 12.43s) is larger thanÂ the stem extract (deviation standard 7.2s). Compared to the use of Abate, the average death of mosquito larva by using leave extract is 26.9 larva per day and compared to the use of stem extract, the average death of mosquito larva is 3.93 larva per day. Economically, we can save Rp 11.350,00/pack if we take Ciplukan leaves and stem to be extracted in which it consists of 10 grams ofÂ Ciplukan leave and stem extract. If the extract or natural Abate is sold, it will cost Rp 650,00/pack; it is more economical than the price of chemical Abate in which price Rp 12.000,00/pack. From the calculation, it is so profitable if we run business on it. We can get back our capital for one year, in which the break event point (BEP) can be reached after selling 162 units which cost Rp 162.000,00 and the profit is more or less Rp 283.000,00/ each production

A complete content of chemical substance from Aloe vera leaf makes this plant has many functions such as the ingredient of functional food for health, cosmetics, and herbal medicines. This research was aimed to determine the yield and quality of Aloe vera L. on various types and rates of green mulch in coastal sandy soil. The research was conducted in coastal sandy soil of Poncosari Srandakan, Bantul, Yogyakarta and done in a Randomized Complete Block Design (RCBD) of two factors with three replications. The first factor was four types of green mulch (shrimp evergreen, cashew, acasia and gliricidia). The second factor was various rate of green mulch consisted of three levels rates of leave mulch (5.0, 10.0, and 15.0 tons ha-1). Soil without mulching was used as a control treatment. The variables observed were yield at the first harvest time and leaf content quality which includes water, protein, fat, carbohydrate, ash, fiber, and mineral (Ca, Fe and Zn). The results showed that there was interaction between types and rates of leave mulch in all variables observed. Gliricidia leaf mulch gave the best effect with optimum rate about of 10 ton ha-1. The effectiveness of green mulch abilities on improving the observed variables from higher order to low was gliricidia, acasia, cashew and shrimp-type evergreen with the rate range between 10 up to 15 tons ha-1.

Penelitian dilaksanakan di Desa Balecatur, Gamping, Sleman mulai Desember sampai Maret 2018. Penelitian disusun dalam Rancangan Acak Kelompok Lengkap faktorial tiga ulangan. Faktor pertama: dosis pupuk AS terdiri atas 150, 250, dan 350 kg per ha. Faktor kedua: sumber rhizobacteria terdiri atas akar bambu, akar gamal, akar kacang tanah, dan kontrol NPK 250 kg per ha. Variabel pengamatan meliputi analisis pertumbuhan dan hasil umbi per ha. Analisis data menggunakan sidik ragam taraf lima persen, dilanjutkan Uji Jarak Berganda Duncan α 5%. Kesimpulan: tidak terjadi interaksi dosis pupuk ZA dengan sumber rhizobacteria terhadap semua variabel pengamatan. Dosis ZA sampai 350 kg per ha tidak meningkatkan pertumbuhan, sedangkan hasil umbi tertinggi diperoleh pada dosis 250 kg, lebih tinggi daripada kontrol. Sumber rhizobacteria gamal memberikan pertumbuhan terbaik, hasil tertinggi diperoleh pada pemberian rhizobacteria bambu.
