    Sheep fattening farms have been recently growing rapidly to produce better quality of sheep meat and fullfill consumer's demand. Sheep fattening and breeding farms should be developed proportionally to obtain sustainable sheep flock in the market. Twelve male lambs (less than one year old) were selected based on their average daily gain (ADG), consisting into two groups: 6 fast growing (FG) and 6 slow growing (SG) sheep. Some morphometric parameters in body and head parts of sheep and their carcass production and composition were measured and compared between the groups. The results show that chest circumference, body height, body length, head length and muzzle, top and bottom neck circumferences of FG sheep were significantly higher than in SG sheep (P0.05). It is concluded that selection of fast growing sheep can be recommended by using some morphometric parameters. The selection would not also negatively affect the weight and percentage of carcass composition

    Bacterial wilt caused by Ralstonia solanacearumis an important disease constraint of groundnut(Arachis hypogaea L.) in tropical and subtropical allover the world. It causing yield losses of 15–35%,and may reach over 65% in groundnut susceptiblevarieties. In Indonesia, the disease have been foundin some areas in North and West Sumatra, Lampung,West Java, Central Java, East Java, Bali, North andSouth Sulawesi. The wilt symptoms can be observedthree weeks after sowing. Infection of plants resultsin rapid wilting of stems and foliage, while leavesretain their green color.There is no desirable method for chemical controlof groundnut wilt, although some bactericidesthat effective against R. solanacearum have beenidentified and available commercially. Other controlstrategy by non-chemically include resistant varieties,healthy seeds, healthy cultivation, biologicalcontrol, and botanical control have been reduced thedisease. Other disease control strategies which ereenvironment-friendly are resistant variety, and theuse of bio control agents. Resistance variety is oneof the most effective means of controlling groundnutwilt and effective to control bacterial wilt in endemicarea and this method could be adopted byfarmer easily. Biocontrol agents i.e. antagonisticbacteria Psudomonas fluorescens (Pf) isolated fromlegumes rhizosphere showed inhibited effect againstbacterial wilt R. solanacearum. The plants extractof some plants such as lemon grass and nut sedgeroots, also showed suppressive effect against bacterialwilt of groundnut

    Kelelahan merupakan salah satu respon tubuh untuk meminta istirahat. Kelelahan ini menyebabkan penurunan performansi kerja baik fisik maupun mental. Pada operator komputer, kelelahan ini dapat menyebabkan cedera pada beberapa bagian tubuh. Pada penelitian ini diambil sampel dari 30 operator komputer dengan rentang usia 19 sampai 32 tahun dengan rata-rata jam kerja 42 jam per minggu.  Dengan menggunakan kuesioner Nordic Body Measurement didapatkan 47% pekerja mengalami sakit punggung bagian atas selama bekerja, 73% sakit pada leher dan bahu, serta 73% mengalami sakit bahu. Hal ini memperlihatkan adanya metode kerja yang harus diperbaiki oleh operator. Oleh karena itu, dengan menggunakan analisis RULA maka didapatkan usulan metode kerja yang lebih baik sehingga dapat mengurangi kemungkinan cedera yang akan dialami oleh pekerja
