Rabbit has potency to produce meat since it has high growth rate, litter size, and short calving interval. Rabbit can utilize low nutritional feed and wide various of forages as its feed. Recently, Indigofera Zollingeriana (IZ) has been widely used as a green protein source in livestock. The used of IZ in rabbit feed seemed to be able to reduce production cost. The study had objective to observe the effect of IZ supplementation in feed to rabbit performance. A number of 72 heads of 12 weeks old of New Zealand white rabbits were used in the study. Rabbits were distributed in three groups of IZ supplementation levels (R1: 0 %; R2: 20 %, and R3: 30%). The supplementation was applicated for five weeks. Data were analysed using one- way ANOVA. The results showed that IZ supplementation effected body weight gain (BWG), feed conversion ratio, and dry matter and energy digestibility (P<0.05). The R2 was the optimal IZ supplementation in the study. The average BWGs of rabbits were 833.38 ± 232 g, 688.50 ± 88 g, and 485.63 ± 130 g for R1, R2, and R3, respectively. In conclusion, the IZ supplementation up to 20 % could be applicated in rabbit feed to reduce cost

This study aims at Identifying the coconut shell charcoal briquette product specifications needed by the Saudi Arabian retail market are in accordance with the characteristics of the briquette products offered in Indonesia, identifying the potential demand for coconut shell charcoal briquettes in the retail market in Saudi Arabia. Also, analyzing the export procedure of Indonesian - Saudi Arabia coconut shell charcoal briquettes. The research method applied in this research uses a descriptive qualitative approach. According to Darmadi (2013), the research method is a scientific way to obtain data for specific uses. The scientific way means that research activities are based on scientific characteristics, namely rational, empirical, and systematic. The author observes the characteristics of briquettes in Saudi Arabia by identifying and interviewing retail and wholesale briquette sellers. The author found several core criteria that standardize briquette products favored by consumers in Saudi Arabia. The author conducts research on the character of briquette products in the Saudi Arabian market and provides advice to Indonesian briquette entrepreneurs to adjust their briquette product standards in order to enter the Saudi Arabian market, and suggests further research should focus on broader research areas in the Middle East.

Rabbits have the potential to produce meat for the animal protein consumption. At present, rabbit farming has developed in Indonesia.The development of rabbit farming is also Rabbits have the potential to produce meat for the animal protein consumption. At present, rabbit farming has developed in Indonesia.The development of rabbit farming is also accompanied by problems in the rabbit productivity. The problem that occurs in rabbit breeders is the low productivity of rabbits. The aim of this research was to identify the effect of force mating to the percentage of pregnancy in New Zealand White (NZW) rabbits at Indonesia Research Institute of Animal Production (IRIAP). The material used in this research were 99 heads New Zealand White (NZW) rabbits in the rabbit station at the IRIAP. The treatment in this study is that the dam of NZW is mated in natural mating and force mating. Pregnancy percentage data were analyzed using T test. The results showed that the percentage of pregnancy between natural and force mating was significantly different (P <.05). The percentage of pregnancy with natural mating in rabbits is higher when compared to force mating, but force mating can to increase the high percentage of pregnancy. The conclusion of the study is that the pregnancy percentage for force mating is lower when compared to natural mating. However, force mating can increase the percentage of pregnancy to reach 74%. by problems in the rabbit productivity. The problem that occurs in rabbit breeders is the low productivity of rabbits.
