Perubahan Mata Pencaharian Petani sebagai Dampak Alih Fungsi Lahan Pertanian : (Kajian Penelitian di Kecamatan Bacukiki Kota Parepare)
No full textThe population of Parepare City, South Sulawesi, has increased yearly. It causes a high need for housing. Unsurprisingly, land that is strategic for agriculture is then used as housing. The economic level of society also influences the conversion of agricultural land. People who cannot meet their daily needs through sales of agricultural activities, which are generally low, try to find other forms of business that can improve their welfare. This research aims to determine the pattern of changes in farmers' livelihoods due to the conversion of agricultural land. This research uses a quantitative descriptive approach. The samples taken were 52 farmers who had sold their agricultural land. Then, the next stage of analysis uses the Wilcoxon test analysis. The research results show that 26.92% of farmers whose land has been converted still work in the agricultural sector, 65.39% in the non-agricultural sector, and 7.69% do not. The conversion of agricultural land to non-agricultural land was expected to improve farmers' economic conditions. However, these conditions are not what is happening in society. The research results show no real influence between the farmers' income before and after the land is converted

Fortifikasi Tepung Daun Pepaya pada Pakan untuk Stimulasi Pertumbuhan Ikan Nila (Oreochromis niloticus)
No full textOne of the fundamental problems in tilapia aquaculture is the decline in water quality in the hatchery. The seed stage is more vulnerable to environmental changes that can reduce the gowth process of seeds and will further cause death. This study aims to determine the effect of fortification of papaya leaf flour (Carica papaya L.) to stimulate tilapia gowth. This study used an experimental method to treat different doses of papaya leaf flour mixed into the feed, namely 0%, 2%, 4%, and 6%, with the test animals used as tilapia seeds measuring 1.4 gams with a length of 3.2 cm. The proximate test results showed that the moisture, ash, crude fat, crude protein, crude fiber, and BETN content were suitable for tilapia fish needs. After 30 days of rearing with the test feed, there was an effect on the specific gowth rate parameters on day 15 and day 30 and the average absolute gowth. The best specific gowth rate (SG) at a dose of 2% was obtained at 6.606% on day 15 and 4.400% on day 30. The best average absolute gowth was obtained at 2% dose feeding with tilapia weight of 6.606 gams and length of 4.400 cm
