Abstract

leaf meal mixture in the basal medium on the utilization of dry matter, crude protein, crude fat, and nutrient conversion in black soldier fly larvae (BSFL). The experiment was designed using a completely randomized design (CRD) with five treatments (0%, 10%, 20%, 30%, and 40% of the Moringa-Leucaena leaf meal mixture) and four replications. The basal medium consisted of 80% rice bran and 20% cornmeal, fermented for seven days before use. A total of 1000 BSFL were introduced into the fermented medium in each experimental unit, and harvesting was conducted on day 14.The results showed that the addition of the Moringa-Leucaena leaf meal mixture significantly increased dry matter utilization (DMU: 0.17–0.33%), crude protein utilization (CPU: 1.21–1.62%), and crude fat utilization (CFU: 4.00–7.00%), while reducing the feed conversion ratio (FCR: 6.23–3.27). The optimal level for all variables was found in the treatment with 40% Moringa-Leucaena leaf meal mixture. In conclusion, the addition of Moringa-Leucaena leaf meal as a protein source in the basal medium can improve nutrient utilization and feed efficiency in black soldier fly larvae.

Abstract

The purpose of this study was to determine the effect of the length of biofermentation time of chromolena odorata with a carbon source of putak flour on the content and digestibility of crude protein and crude fat in vitro. The research method used is an experimental method (experimental) with a Complete Random Design pattern consisting of 4 treatments and 4 repeats so that there are 16 experimental units. The treatment used is LB21: biofermentation duration 21 days (As control), LB14: biofermentation duration 14 days, LB7: biofermentation duration 7 days, LB0: biofermentation duration 0 days. The data were obtained and analyzed by variety analysis (ANOVA), and continued with the Duncan multiple distance test to determine the effect between treatments. The results of statistical analysis showed that the length of biofermentation of Chromolaena odorata with the carbon source of putak  flour had a real effect (P<0,01) On crude protein content, crude fat content and crude protein digestibility in vitro, while on crude fat digestibility in vitro the effect is not real (P<0,05). It can be concluded that the length of biofermnetation of Chromolaena odorata with putak flour source affects crude protein content, crude fat and gauze protein digestibility in vitro but does not affect crude fat digestibility in vitro.

Abstract

The main problem in the cultivation of Mucuna bracteata is the hardness of the seed coat, which results in low seed dormancy. The aim of this study was to examine the effectiveness of different seed scarification methods on the growth of M. bracteata plants. This research was conducted at Prof. Bale-Therik's farm in Noelbaki Village, Kupang Tengah Subdistrict, Kupang Regency, for 21 days. This research used a completely randomized design (CRD) of 4 treatments and 5 replicates, with each replicate consisting of 15 seeds. The treatments consisted of control (SB0); seeds soaked in warm water at 50°C for 2 hours (SB1); seeds soaked in normal temperature water for 24 hours (SB2); and seeds scarified (SB3). Data obtained during the study were analyzed using analysis of variance to test the effect of treatment with an alpha value of 0.05. Differences between treatments were tested by Duncan's multiple range test. The results showed that seed scarification had a very significant effect (p<0.01) on all parameters measured. SB3 treatment significantly accelerated leaf emergence (6.21 days), number of leaves (27.47 strands), leaf length (15.51 cm), leaf width (9.89 cm), the onset of tendril growth (8.33 days), tendril length (117.16 cm), and tendril growth rate (6.89 cm day-1). It was concluded that the seed scarification technique (SB3) was the best treatment because it could influence and improve the growth of M. bracteata plants.

Abstract

This study aims to determine the chemical quality and fermentability of the rumen contents of female Bali Timor cattle in vitro. This research used an experimental method with T-test analysis (comparative test). The number of samples for each was 15 female Timor Bali cattle as replicates, taken from two different slaughterhouses, namely Bimoku abattoir (government-owned) and Aldia Oben abattoir (privately owned). The variables observed were crude protein, crude fiber content, and concentrations of VFA and NH3. The data obtained were analyzed using a T-test (independent sample t-test) at a significance level of 5%, namely comparing the quality of the cattle rumen contents of Bimoku and Oben abbatoir. All data were processed with SPSS 25 software. The statistical analysis results of the t-test showed that the crude protein content and concentration of NH3 of the two locations was not significantly different (P> 0.05), the crude fiber content of Bimoku RPH was significantly higher (P<0.05) than RPH Oben, and VFA concentration from RPH Oben was significantly (P<0.05) higher than Bimoku RPH. It was concluded that differences in abattoir management before slaughtering affected the quality of the rumen contents of female Timor Bali cattle

Abstract

The aims of this study was to determine the effect of the length of time of Chromolaena odorata biofermentation with putak flour carbon source on methane production, pH, NH3 and Total VFA in-vitro. The main materials used were Chromolaena odorata, putak flour, and rumen fluid.  The method used was an experimental method with a completely randomised design (CRD) pattern consisting of 4 treatments and 4 replications. The treatments were LBf21 = 21 days biofermentation duration (as control); LBf14 = 14 days biofermentation duration; LBf7 = 7 days biofermentation duration; LBf0 = 0 days biofermentation duration. The variables studied were Methane Production, pH, NH3 and VFA in-vitro.  The results of statistical analysis on the variables of methane production, NH3 and total VFA showed that the treatment had no significant effect (P>0.05), while the pH value statistically showed that the treatment had a significant effect (P<0.05) on the length of time of biofermentation of Chromolaena odorata silage. It is concluded that the length of time of the biofermentation process has not been able to increase the production of total VFA, NH3, and reduce methane production but is able to increase the pH value of Chromolaena odorata silage silage from the biofermentation process.

Abstract

The purpose of this study was to determine the effect of the addition of liquid palm sugar as a carbon source in the Chromolaena odorata biofermentation process on cellulose, lignin, phytic acid, nitrite and saponin content. This study used a completely randomized design (CRD) with 4 treatments and 4 replicates. The treatments were: LB0 = 0 days of biofermentation, LB7 = 7 days of biofermentation, LB14 = 14 days of biofermentation, and LB21 = 21 days of biofermentation. The variables observed were cellulose, lignin, phytic acid, nitrite and saponin content. The data obtained were analyzed using Analysis of Variance and Duncan's test. The results showed that the length of biofermentation time significantly decreased cellulose content with a range of (23.52-19.26%), lignin (13.75-8.72%), phytic acid (4.03-2.00%), nitrite content (6.60-4.73ppm), and saponin (7.68-5.84%). It was concluded that the length of Chromolaena odorata biofermentation time decreased the content of cellulose, lignin, phytic acid, nitrite content and saponins with varying lengths of biofermentation time, namely the length of biofermentation time of 7 days (LB7) getting a total value of cellulose content (20, 40%), lignin (9.23%), the length of biofermentation time of 14 days get the total value of phytic acid content (2.23%), nitrite (4.86ppm) and the length of biofermentation time of 21 days get the total value of saponin content (5.84%).
