Abstract

The aim of this research was to revegetate the disused limestone quarry by introducing dwarf elephant grass (Pennisetum purpureum cv. Mott) and annual legumes such as peanuts (Arachis hypogaea L.), soybeans (Glycine max), cowpeas (Vigna unguiculata) and  mung beans (Vigna radiata). The study was conducted experimentally in a disused limestone quarry applying Completely Randomized Design. The research method used was experimental in disused limestone mining in karst Gombong area applying Completely Randomized Design (CRD). Treatment consisted of 6 planting methods with 4 replicates. The 6 treatments research were the followings: RO: Single planting of dwarf elephant grass,  R1: Single planting of dwarf elephant grass + 1.5 kg/m2 goat compost,  R2: Mixture Planting of dwarf elephant grass + legume peanuts + 1.5 kg/m2 goat compost,  R3: Mixture planting of dwarf elephant grass + legume soybeans + 1.5 kg/m2 goat compost,  R4: Mixture planting of dwarf elephant grass + legume cowpeas + 1.5 kg/m2 goat compost and R5: Mixture planting of dwarf elephant grass + legume mung beans + 1.5 kg/m2 goat compost. The measured response variables were plant’s height, fresh yield, dry matter yield and crude protein content of dwarf elephant grass aged 8 weeks. The result showed that the addition of goat compost and the planting method of annual legumes on the disused limestone quarry had highly significant influence (P<0.01) on the increase productivity and quality of dwarf elephant grass. The best method of planting dwarf elephant grass (Pennisetum purpureum cv. Mott) on disused limestone mining in karst Gombong area is mixture planting with soybean legumes (Glycine max) and adding the 1.5 kg/m2 goat compost.

Abstract

The aim of this study was to determine the morphology of local sweet potato (Ipomoea batatas) leaf waste as forage in disused limestone mining areas were fertilized by goat compost litter. The method used in this research was an experimental method in the disused limestone mining area by using a factorial pattern with a completed randomized design, each treatment was repeated 3 times. Factor I was three types of local sweet potatoes, namely purple (U), white (P) and yellow (K) sweet potatoes, while the Factor II was the level of goat litter fertilization, namely k1: Level of goat litter fertilization 0.5 kg. / m2, k2: 1 kg / m2, k3: 1.5 kg / m2 and k4: 2 kg / m2. The morphology of sweet potato leaf waste was measuredby the number of leaf, the width of leaf, the length of leaf stalk and the weight of leaf . The results showed that the local type of sweet potato had significant different (P < 0.05) but the level of goat compost litter fertilization had no significant different (P > 0.05) on the morphology.  Judging from the, it can be concluded that the waste of orange (O) sweet potato leaf with goat litter fertilization of at least 1 kg/m2 or 10 tons/ha has a high morphology, so that the amount of sweet potato leafwaste which was produced for the forage will be high.

Abstract

Daging gelonggongan adalah daging yang diperoleh dari hewan yang sebelum disembelih terlebih dahulu diberi minum air secara berlebihan. Tujuan dari pemberian minum berlebih itu adalah untuk mendapatkan timbangan lebih berat. Daging gelonggongan ini tidak hanya merugikan konsumen secara materi, karena juga bisa memicu keracunan, bahkan kematian. Ini terjadi karena daging gelonggongan ini bisa mengandung bakteri buruk yang mengancam kesehatan konsumen. Sampai saat ini masih saja ada konsumen yang membeli daging sapi gelonggongan ini. Kemungkinan konsumen menyukai daging sapi gelonggongan, karena harganya relatif lebih murah, mungkin juga karena konsumen tidak tahu kalau daging yang dijual tersebut adalah daging gelonggongan. Agar peredaran daging sapi gelonggongan tidak semakin meluas, ada dua hal yang perlu dilakukan. Pertama, konsumen harus mengetahui ciri-ciri daging gelonggongan dan jangan mau membeli daging sapi gelonggongan tersebut. Kedua, aparat harus menindak tegas para pelaku usaha daging gelonggongan, baik yang memproduksi maupun pedagang daging sapi gelonggongan. Gelonggongan beef is beef obtained from cow before slaughter first given to excess drinking water. The purpose of granting excessive drinking is to get heavier weights. Gelonggongan beef is not only materially harm consumers, but also it can lead to poisoning and even death. This occurs because the gelonggongan beef may contain bad bacteria that threaten consumer health. Until now, there are consumers who still buy gelonggongan beef. Maybe consumers like gelonggongan beef, because the price is relatively cheap, perhaps because consumers do not know if the beef sold is gelonggongan beef. For the circulation of beef gelonggongan not more widespread, there are two things that need to be done. First, consumers must know the characteristics of gelonggongan beef and do not want to buy these gelonggongan beef. Second, the authorities must take firm action against the perpetrators gelonggongan beef business, which manufactures and traders both beef gelonggongan.
