Abstract

            Vegetation that grows naturally in certain areas is a reflection of the interaction of various environmental factors and may change at any time. Under oil palm trees, there are several types of vegetation that have the potential to be used as animal feed, but it has not been identified yet. This study aimed to examine the types of vegetation that grows under the oil palm trees, and could potentially be used for animal feed. Observations were conducted on 3 groups of oil palm plantations aged above 10 years which belong to:  i.e. smallholder oil palm, private estates, and state estates company. In each group, it was taken 8 plots so there were 24 plots in total. Parameters observed were the types of plants (i.e. grass, legume, and weed), plant nutrient content (determined by using proximate analysis), microclimate and soil organic matter content (C and N), and soil pH. Collected data were analyzed descriptively, and were followed by a t test.   Results showed that herbages grow in palm-oil plantation in the Ness village are more various than that of in the Arang-arang village.  Ottocloa nodosa and Eulisine indica are two grasses species that might be potential in the Arang-arang village which has a pity soil type, while Leersia hexandra, Paspalum sp., and Ottocloa nodosa are species of grasses which grow in the Ness village which has a yellow-red podsolic soil type.  The existence of Melastoma malabathricum in the Arang-arang village should be considered as this species contains poisonous substances.  Calopogonium sp. and Mimosa sp. are spesies of legumes that could be developed in palm-oil pasture to improve N content of herbages.  Nitrogen or mineral fertilization might be needed to improve soil fertility of different soil types.Key words: oil palm, vegetation, weeds, animal feed, soil

Abstract

Turmeric is a type of root that is easy to obtain, contains chemical compounds that have physiological activities, namely essential oils (containing sesquiterpenic alcohol compounds, temuron and zingberen) as well as curcuminoids (containing curcumin and yellow which include desmotoxicurcumin and bidesmetoxicurcumin compounds). This study aimed to determine the use of turmeric level in drinking water on the performance of quail during the production period, in terms of ration consumption, egg production and ration conversion of quails. This research has been carried out in Petobo Village, South Palu Subdistrict, on March 1 to April 15, 2017. This study used 200 female 12-week-old quail, 10 quails were placed in each cage unit. This study used a Completely Randomized Design (CRD), consisting of 4 treatments with 5 replications. The treatments tried are as follows: R0 = Without using turmeric flour in drinking water; R1 = 1 gram of turmeric flour in 1000 ml of drinking water; R2 = 2 grams of turmeric flour in 1000 ml of drinking water; R3 = 3 grams of turmeric flour in 1000 ml of drinking water. The results of the variance analysis showed that the addition of turmeric flour in quail drinking water had no significant effect (P> 0.05) on ration consumption, however a very significant effect (P <0.01) on quail egg production and ration conversion. The conclusion of this study is the use of turmeric flour in drinking water increases egg production and decreases ration conversion.Keyword: Quail, Turmeric, Production Performance

Abstract

This study aimed to determine the level of need and mechanism of fishermen insurance in sekaya maritim, as well as to find out the impacts that arise and strategies for developing fishermen insurance, thus it can be felt by other fishing communities. Data collection were carried out by literature study and field studies through interviews, observation and documentation. Sampling was done with a purposive sampling method with total of 70 respondents. The results showed that several factors that caused the importance of fishermen's insurance needs were the number of family members, the age of the fisherman, and the working hours of fishermen. Fishermen who have fulfilled the requirements for Fishermen Premise Insurance Assistance (Bantuan Premis Asuransi Nelayan/BPAN) are given an Insurance Card and Realization Policy. A total of 8 fishermen families have received insurance, hence they can improve their economic condition. The fishermen insurance development strategy is that fishermen who have met the insurance participant requirements can enjoy the benefit of insurance every year.Keywords: Fishermen insurance, Sekaya maritim, Development strategy.
