Cloth construction is on catalog that use for woven cloth producer and some information and
Inside of quality test textile material clothing, consist of cloth weight test, strength full cloth test, cloth rumpled test and measurement change test after washing. While the component of woven cloth construction consist qt‘ warp compact yarn, weft compact yam, number of warp, number of weft and the width of cloth.
From the ﬁfth component of woven cloth construction in the dijﬁzrent variety a woven cloth will be a chieve diﬂerent quality of woven cloth, the changes of cloth construction will be inﬂuence to the quality of woven cloth as an measure wouen cloth.
Key words : woven cloth Construction, quality woven cloth, textile material cloth

Clove oil industry , temperature dissociation energy of diatomic is principal dissociation energy of diatomic required to process distillation takeplace .In distillation can be conventional , loss of external air, temperature dissociation energy of diatomic is not paid attention . re- design is distillation device of conventional oil of clove meant to increase efficiency from the device by the way of optimal of temperature dissociation energy of diatomic yielded from fuel baking.
Redesigned technology provides installation around the boiler pipes and oil separator with a better construction material isolation having 0.02m thickness.its called a glasswool the heat conductivity of this glasswool is 0,07 W/M.K.The matrial of oil separator is stainless steel with 0.005 M thickness by isolation, The boiler pipes have low temperature gradient at each altitude distillation boiller.Obtained low temperature gradient at each boiler pippes .Steam boiler in the boiler is more secure in the oil yield could be incre sead by 4,17% .With the use of agood oil separators,clove oil can be produced much more secure oil cleane, increased by 12,51% .
Key words : Destilations,heating surface,yield,temperature gradients

The problem experienced by KUPP Mekarsari in producing pressed tile roof is the non homogen
The results show that the contribution to minimise water absorbtion from each independent variables are as folow: roll diameter is 40.52%, motor rotation is 6.97%, the distance between the rools is 11.197% and the soils composition is 8.9%. Meanwhile the contribution to maximise the flexural strength are: roll diameter is 22.079%, motor rotation is 21.267%, the distance between the rools is 6.558% and the soils composition is 31.968%. The minimum water absorbtion at the setting of: 200 mm roll diameter, 1000 rpm motor rotation, 3 mm distance between the rolls and the soils composition of 1 clay: 0.5 sand: 0.25 Kaolin (A1B1C1D1) could be achieved to produce homogen mixture. The maximum flexural strength is required at the setting of: 225 mm roll diameter, 1250 rpm motor rotation, 5 mm distance between the rolls and the soils composition of 1 clay: 0.5 sand: 0.5 Kaolin (A2B2C2D2).

The most representative coagulant substance to be used for liquid chemical waste processing from comprehensive textile industri is FeSO 4. It can be regarded as the most dependable because it can change the colours of liquid waste and able to reduce BOD,COD, Disolved solid substance and Suspension solid substance in a bigger amount than other coagulants. By the addition of FeSO 4 2 g/l + CaO 1 g/l + Anionik Polimer 0,125 g/l in coagulant-sedimentation waste proccess, BOD level can be reduced as much as 78 – 85%, COD 70 – 76%, Disolved Solid substance 30 – 34% and Suspension solid substance 91-95%. The use of FeSO 4 in waste processing can needs lesser time to sediment than other coagulants, its less expensive cost in waste processing, operational cost can be pressed.
Key Words : Coagulation – Sedimentation, Ferro Sulfate, coagulant, textile liquid waste.
