Abstract

ABSTRAK Sistem produksi ternak sapi perah dapat mengakibatkan pencemaran lingkungan berupa bau menyengat yang ditimbulkan oleh gas NH3 dan H2S  limbah ternak. Tingkat kebauan NH3 dan H2S dipengaruhi oleh  kondisi lingkungan dan perilaku peternak dalam pengelolaan limbah ternak. Penelitian dengan menggunakan metode survey pada peternakan sapi perah rakyat di Provinsi Jawa Tengah dilakukan untuk mengetahui pengaruh kondisi lingkungan dan perilaku peternak terhadap tingkat kebauan. Wilayah penelitian dikelompokan menjadi tiga wilayah yaitu kondisi lingkungan dan perilaku peternak tinggi (LPT); kondisi lingkungan dan perilaku peternak sedang (LPS) dan wilayah untuk kondisi lingkungan dan perilaku peternak rendah (LPR). Penentuan wilayah sampai dengan lokasi peternak terpilih ditentukan secara purposive sampling berdasarkan kriteria yang telah ditentukan.  Hasil penelitian menunjukkan bahwa wilayah dengan kondisi lingkungan dan perilaku peternak rendah (LPR)  adalah wilayah yang tercemar limbah peternakan sapi perah, karena mempunyai tingkat kebauan H2S yang telah melampaui baku mutu.   Kata Kunci : sapi perah, lingkungan, tingkat kebauan   EFFECT OF DAIRY CATTLE WASTE MANAGEMENT ODOR ABSTRACT Dairy production systems can cause environmental contamination in the form of nasty odor caused by NH3 and H2S gas from the livestock waste. The odor levels of NH3 and H2S are influenced by environmental conditions and farmers behavior of in waste management. The research using survey methods at the dairy cattle ranch in Central Java carried out to determine the effect of environmental conditions and farmers behavior towards the odor cases. Research areas are grouped into three areas, namely high of both condition environmental and the farmers behavior, medium of both condition environmental and the farmers behavior and areas for the low of both condition environmental and the farmers  behavior. Determination of the region up to the location of the selected farmers  is specified using purposive sampling based on the determined criteria. The results showed that the low of both condition environmental and the farmers  behavior is the area of contaminated dairy cattle farm waste, because it has the H2S levels that have exceeded the quality standard. Key words: dairy cattle, environment, odor levels

Abstract

ABSTRAKSI   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 AND PUBLIC HEALTH ABSTRACT 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.

Abstract

Research aims to conduct diversity and productivity of indigenous forage in different levels vegetation density in Gombong-Selatan karst mountain. We used survey method to explain the research by sampled three location of vegetation density, they are moderate, high, and very high. In each location vegetation density we take five parts by using random sampling. Then, a descriptive technique is used to analyzed the indigenous forage diversity data result whereas variance analysis is used to analyzed the productivity.The results shows the highest diversity of indigenous forage in Gombong-Selatan karst mountain is in moderate vegetation density area where has 36 species, high vegetation density has 20 species, and the highest vegetation density has 16 species. Eragrotis amabillis, Oplismenus burmannii, Centrosema pubescens, Ageratum conyzoides and Urena lobata are the dominant indegenous forage species in Gombong-Selatan karst mountain. The variances result shows that indigenous forage productivity in Gombong Selatan karst mountain is influenced by vegetation density. We found that lowest productivity is in high vegetation density.

Abstract

The negative impact of limestone mining on a karst area around Gombong is the destruction of ecosystem. Ecosystem’s destruction will decrease the variety, productivity, quality and continuity of indigenous livestock forages. The aim of this research is to know the growth rate of Dwarf Elephant grass (Pennisetum purpureum Mott) in the post mining limestone with various methods of planting. The method used in this research is an experimental method in an open field that was used for limestone mining by using Completed Random Design. The treatment consists of 4 kinds of planting methods with 4 repetitions, while the research treatment used in this experiment is the RG (the field with Dwarf Elephant Grass); RGL (the field with Dwarf Elephant Grass + peanut legume); RGK (the field with Dwarf Elephant Grass + goat’s compost 1,5 kg/m2) and RGKL (the field with Dwarf Elephant Grass + peanut legume + goat’s compost 1,5 kg/m2). The parameter used for the research is the growth rate which includes the plant’s height, the length of the leaves, and also the width of Dwarf Elephant Grass’s leaves (Pennisetum purpureum ‘Mott’) until the 8th week.The result of this research shows that the use of goat’s compost 1,5 kg/m2 and planting of peanut can give significant results to the growth of Dwarf Elephant Grass in open field that was used for limestone mining.
