Abstract Liquid smoke has many benefits, especially in the food, fishery, timber, and plantation industries. It is used as a preservative or durability increased and aroma and taste addition in the food and fishery industry. In the wood industry, liquid smoke can resist termite attacks, while in the plantation industry, it functions as a latex coagulant containing antifungal, antibacterial, and antioxidants that can improve rubber product’s quality. Most of the rubber farmers in Bangka Belitung still use alum as a coagulant to coagulate their latex. However, alum coagulant can reduce the quality of the processed rubber material (bokar). The reason farmers use alum is that raw materials are cheap, therefore getting coagulant raw materials at low prices and not pollute the environment with a less moderate aroma/odor caused by non-recommended coagulant materials (alum) are needed. This study aims to apply liquid smoke as a natural coagulant in latex freezing. The research method used a Completely Randomized Design, with liquid smoke concentration replicated three times. Parameters observed were clotting time speed and organoleptic test for odor during 14 days of storage. The results showed that the best concentration of liquid smoke was 15% no odor and a clotting time of 8.23 minutes.

ABSTRACT THE EFFECT OF VARIOUS COMMERCIAL RATIONS COMBINED WITH DIFFERENT CAGE SYSTEM ON CARCASS QUALITY OF BROILERS. The objective of this research was to determine carcass quality of broilers fed with three forms of commercial ration using 2 different cages. Total of 96 day old chicks were used in this study using four animals in each cage. Research was conducted using a completely randomized design divided into 3x2 patterns of treatment with 4 replications. Three forms of commercial ration (Factor A) consisted of A1 = Pokhpand Ration (CP 11 ); A2 = Cargill Ration (Avibro) and A3 = Sierad Ration (BSG 101). Two different cages (Factor B) consisted of B1 = Battery Cage ; B2 = Litter System. The results showed that three forms of commercial ration combined with two different cage systems give the same effect on carcass quality of broilers in terms of carcass percentage and abdominal fat weight. Litter system and animal slaughter at 6 weeks of age reduced the risk of breast blisters. Keywords: Rations, cage, broiler, carcass quality.

The centre of bamboo crafts in Gunung Sari District is the largest bamboo centre in West Lombok Regency. One of the bamboo species which is usually used as raw materials is tali bamboo. Studies of physical properties of this bamboo have not been carried out resulting poor quality of bamboo crafts. The physical property was essensial information which would be used for enhancing the products because it correlated with dimensional stability of the bamboo. The objectives of this study were to identify the physical properties of the bamboo with reference to the axial direction. The experiment design was complete random design employing the axial directions (bottom, middle, and top portions) as treatments. The statistical analyses were Anova with range tests at α = 5%. The results showed that the physical properties were: fresh moisture content 51-119.82%; air-dried moisture content 13.03-15.04%; fresh volume density 0.51 – 0.72; air-dried volume density 0.62 – 0.75; oven volume density 0.63 – 0.78. Axial directions of the physical properties were not significantly different except for the fresh moisture content. Therefore all portions of tali bamboo (bottom, middle, and top portions) could be utilized as raw materials for bamboo crafts.
