Abstract

An investigation on diversity monitoring of ginger family (Zingiberaceae) was carried out on Jengok, Banjaran, Kranji, and Pelus riverbanks in Purwokerto. This study required conventional surveys and repeated measurements to identify and to evaluate changes. Twelve permanent plots were established in 1990 covering the north, central, and south parts of the rivers. The ginger vegetation in 2005 was compared with data taken in 1990, 1997, and 2003. The result of this study showed that the number of spesies in most of the bank reached the peak in 2003 then decreased again in 2005.

Abstract

Objectives of this research were to measure effects of land use types and physical environmental condition toward level of erosion hazard as indicators on watershed management. Using survey and non experimental approaches, this research was conducted on September to December 2005. Applying quantitative model such us Universal Soil Loss Equation (USLE) and stepwise regression procedure, it was found that on open land (with more than 15 % slope steepness) and plantation area (with more than 40 % slope steepness) were significantly increasing actual erosion to 4.005 t/ha/thn and 2.807 t/ha/thn.   Moreover erosion hazard index for open land was 99 t/ha/year and for plantation area was 81,78 t/ha/year in which categorized as medium level. Most of the land use types contributed the amount erosion more than tolerance level (34,33 t/ha/year – 44,67 t/ha/year). The influenece of open land  and  plantatation area variables on increasing erosion hazard were 3.39 and 0.592 times more than their unit areas respectively with determinan coeficien  (R2) was 0,88.

Abstract

This paper describes a study finding on the determination of various policy alternatives based on biological, technological, social and economical aspects that may be suitably applied for development of purse seine fishery. This study was conducted in the District of Parigi Moutong, Central Sulawesi from January to April 2006. This study involved 5 purse seines and their owners determined using a cencus sampling technique and 20 purposedly sampled fishermen. The primnary data collected were the yield of captured fish. The policy analyses was done using an Analytical Hierarchi Process (AHP) with Expert Choice 9.0 software on a personal computer. Results showed that adding purse seines (a ranking value of 0.49) was the most important policy that may be taken in overall effort in a sustainalbe fishery development while maintaining their current number (a values of 0.32) was considered as a moderate choice and removing it was shown to be a contradictory policy

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh komposisi asam lemak (fatty acid) dalam makanan terhadap pertumbuhan dan kelangsungan hidup post larva (PL) udang kuruma, Penaeus japonicus. Disamping itu, komposisi dan mekanisme transfer asam lemak diuji sesuai urutan rantai makanan: algae, Artemia dan udang. Hasil penelitian menunjukkan bahwa bobot badan (Body Weight=BW) tertinggi dicapai oleh udang yang mengkonsumsi Artemia pemakan algae, Isochrysis galbana (T.Iso) (P<0,05). Sedangkan untuk panjang total (Total Lenght=TL) tertinggi ditunjukkan oleh udang-udang yang mengkonsumsi Artemia pemakan algae, T.Iso dan yang mengkonsumsi Artemia pemakan algae, Tetraselmis  suecica. Makanan alami Artemia lebih baik untuk pertumbuhan larva udang dibanding makanan buatan. Artemia dapat mentransfer zat-zat gizi khususnya asam lemak yang terdapat dalam algae ke udang. Dalam keadaan lapar, katabolisme asam lemak terjadi dalam tubuh udang, dan asam lemak ganda tak jenuh omega 3 lebih efektif untuk mendukung pertumbuhan udang dibanding omega 6. Keseimbangan komposisi antar  berbagai asam lemak ganda tak jenuh kemungkinan sangat penting untuk pertumbuhan udang.

Abstract

The nutrient mapping objectivity is 1) Information and data can lowland on P and K nutrient, 2) Lowland cover account for level P and K status. The using impact is efficient and rational for P and K. Fertilizing recommended of paddy, the fertilizer need efficient is guiden soil nutrient status. Analysis program on the chemical element status of the ricefield P and K in 2003 is located in Maos Subdistrict of Cilacap Regency. Methodology use comprises: preparation, operation of soil sample taking and analysis of soil. Main Survey performs the sample talking of individual soil which is become as sample of comphosit sample, 1 sample of chomposit sample consist of 10- 15 sample of individual soil. The next level is sample of chomposit, show much 156 cohmposit soil, the data from the result of soil analysis of the content P and K through 3 status (low criteria, middle and high). Commonly.  The result of the status mapping on the ricefield P and K is as follows: there are 156 samples of soil of the chemical element status P; low up to high of Maos Subdistrict, the middle status is 31-38 mg/100 mg P2O5 or 735,052 hectars wide; and the high status is 50-77 mg / 100 g P2O5 with 1258,282 hectars wide, but the status of middle chemical element K is 14-18 mg/100 g P2O5 with 1.696,649 hectars wide and the status of high K is 22-37 mg/100 g K2O with 400,738 hectars wide by doing fertilizing suitable with the result of soil analysis, so the cost can be economized for Rp 370 259 63,-1 per season for the buying of the fertilizer SP-36 and Rp 35. 093.520 per planting season for the buying of the fertilizer KCL.

Abstract

This experiment was intended to study effects application time of bokashi cocoa pod husk and dosage of inorganic fertilizer mixture on the growth and yield of sweet corn.  The experiment employed a factorial randomized block design with two factors. The first factor was two levels of the bokashi application time: two or one week before planting time. The second factor was three dosages of organic fertilizer:  133.3 kg/ha of urea + 100 kg/ha of SP-36 + 83.3 kg/ha of KCL, 266.6 kg/ha of urea + 200 kg/ha of SP-36 + 166.6 kg/ha of KCl, and 400 kg/ha of urea + 300 kg/ha of SP-36 + 250 kg/ha of KCl. Data were analyzed with honestly significant difference (HSD) at 5 % significant level. Results showed there was no interaction between the two factors in affecting the parameters observed. It showed that time application of bokashi cocoa pod husk significantly affected the length of corn cob, while the inorganic fertilizer significantly affected the weight of corn cob. Results of the HSD test indicated that the best corn cob length (22.96 cm) was obtained for one week bokashi application prior to planting with inorganic fertilizer of  400 kg/ha of urea + 300 kg/ha of SP-36 + 250 kg/ha of KCl.

Abstract

This research was done at the eksperimental station Pengawu Sub District, South Palu District, City of Palu, Central Sulawesi Province. For 10 week from Mei 19, until August 11, 2005. this research was aimed at studying body weight and carcass percentage of male Kacang goat at different time of diet giving. Fitteen male Kacang goat aged of 10 – 12 months with 10,10 – 16,10 early body weight from local farmer around Palu City were used. The goats were in individual confinement with 15 individual size of 75 x 75 x 75 where each confinement was put food and water. Environmental design used for this research is a completely Randomized Design with coisist of treatments and 3 groups as replications. The treatments were allocated with 5 differents of eating time, i.e. WM1 (diet giving at 8 am), WM2 (diet giving at 9.30 am), WM3 (diet giving at 11 am), WM4 (diet giving at 12.30 pm)   WM5 (diet giving at at 2 pm). Results showed that diet giving at different time gave very significant effect (P<0,01) on both of the parameters observed
