Abstract

This study aimed to determine the coefficient of total calcium and phosphorus digestibility effects from limestone as a source of calcium and the effect of phytase enzymes on laying hens. This study used 180 Hy-line Brown laying hens aged 75 weeks. The experimental design used was a 2x2 factorial complete randomized design (CRD) with 9 replications. The first factor was limestone particle size, i.e., P1 = limestone flour and P2 = limestone granules, and the second factor was phytase enzyme dose, i.e., Q1 = 0 FTU and Q2 = 1000 FTU. The observed variables were gizzard pH, excreta moisture content (MC), digesta MC, calcium and phosphorus digestibility using two samples and ileal digestibility. The results showed that the digestibility of calcium from limestone flour was significantly different compared to limestone granules at P<0.05. The phytase addition and the interaction with limestone particle size did not affect gizzard pH, total and ileal digestibility of calcium and phosphorus. Excreta and digesta MC had a significant effect on the particle size of limestone, the highest MC was limestone granules compared to flour (P<0.001). The addition of phytase had an effect on reducing excreta MC (P< 0.001). There was interaction between limestone size and phytase in excreta and digesta MC. The conclusion of the research was that laying hens were more efficient in digesting calcium from limestone flour compared to limestone granules. Phytase could reduce excreta and digesta MC. Key words: calcium, digestibility, limestone, particle size, phytase

Abstract

This study aimed to evaluate the utilization of liquid probiotics from black soldier fly larvae (BSFL) fermentation on broiler chickens' performance. A total of 250 male broilers strain Cobb CP 707 were given 5 treatments of probiotics in drinking water with 5 replications using a completely randomized design. The treatments in this study were P0=commercial broiler feed+drinking water without probiotics, P1=commercial broiler chicken feed+ drinking water with 1 mL L-1 commercial probiotic, P2=commercial broiler chicken feed+water with 1 mL L-1 probiotics from BSFL fermentation, P3=commercial boiler chicken feed+water with 3 mL L-1 probiotics from BSFL fermentation, and P4=commercial broiler chicken feed+water with 5 mL L-1 probiotics from BSFL fermentation. The results showed that BSFL fermentation probiotics were not significantly different on broiler chicken performance. Income over feed and chick cost (IOFCC) in addition to 5 mL L-1 in drinking water was more efficient in saving feed cost and the highest performance index during the broiler rearing. In conclusion, the utilization of BSFL fermentation probiotics in drinking water gave the same effect on broiler chicken performance as the other treatments yet the IOFCC and broiler chicken performance index were more advantageous. Key words: black soldier fly larvae, broiler, performance, probiotics

Abstract

This study aimed to analyze the viability of probiotics from maggot fermentation under environmental influence i.e., temperature and storage time. The experimental design was a factorial completely randomized design (CRD) using storage time and temperature as factors with 4 replications. The storage time was 3 months with monthly observations while the storage temperatures observed were 4°C, 28°C, 38°C and 48°C. The parameters were physical quality, microbial population, total titrated acid (TTA), and antimicrobial activity. The results showed that probiotics from maggot fermentation were dominated by lactic acid bacteria. The pH of probiotics increased and physical quality changes occured during storage. The yeast and actinomycete populations were not found during month 2 and month 3, respectively, while the population of Bacillus sp. decreased. There was an interaction between storage time and temperature on the population of lactic acid bacteria and TTA. Another interaction was found in the antimicrobial activity produced by probiotics/antibiotics and storage temperature in the third month of storage. Storage time and temperature influenced the physical quality of probiotics, the population of lactic acid bacteria and TTA, while the inhibition zone was influenced by the probiotic/antibiotic solution and storage temperature. It can be concluded that the highest viability of fermented maggot probiotics (LAB) was obtained in the 1st month at a temperature of 38℃. Key words: maggot fermentation, probiotics, storage time, temperature, viability

Abstract

Perguruan tinggi sebagai tempat insan akademik berkiprah saat ini mengalami berbagai tantangan dan ancaman yang dapat mengganggu fungsinya sebagai pusat pengembangan ilmu pengetahuan dan teknologi (iptek), serta menjadi penjaga keberlanjutan peradaban dan moralitas insan akademik agar tidak terdistorsi dan tererosi. Kemajuan teknologi (khususnya teknologi informasi), dekadensi moral global, tekanan ekonomi, orientasi praktis dan fokus pada pencapaian jangka pendek, perubahan paradigma pendidikan serta iklim ketidakpastian, menjadikan nilai-nilai tradisional perguruan tinggi terancam tergeser menjadi mesin penghasil tenaga kerja semata. Perguruan tinggi, yang seharusnya berperan sebagai benteng terakhir penjaga nilai-nilai akademik, serta sebagai agen perubahan (agent of change) yang berorientasi pada nilai kebaikan dan penjaga nilai moral (guardian of value), perlu jati diri insan akademik yang unggul, sehingga peran dan fungsi perguruan tinggi dapat tetap dipertahankan. Untuk memberikan pertimbangan dalam upaya menjaga tersebut, Policy Brief ini disusun melalui serangkaian proses diskusi anggota tim PAH Jati Diri Insan Akademik dan proses FGD yang melibatkan narasumber internal dan eksternal IPB. Policy Brief ini diakhiri dengan rekomendasi yang dapat diusulkan kepada penyelenggara pendidikan tinggi Indonesia agar fungsi perguruan tinggi dan insan akademik dapat tetap terjaga

Abstract

In today's technological advances, people have used motorized vehicles, one of which is a motorbike as a means of transportation in everyday life as a facility for activities such as work. However, the motorcycle security system currently still uses conventional locks that are easily damaged by thieves in a short time which can result in material and non-material losses for motorcycle owners. One of the automotive technologies that can increase the comfort and convenience of motorcycle users is by introducing a more sophisticated and easy engine start and motorcycle safety system through an Android smartphone. The system development method used in this study is the waterfall method. This development model is linear from the early stages of system development, namely the planning stage to the final stage of system development, namely the maintenance stage. The purpose of this research is to design a tool using the Arduino Microcontroller to control the Start Engine and Motorcycle Alarm, create an android application that functions as a remote to control the Start Engine and Motorcycle Alarm, increase motorcycle security with an alarm as a security system, make it easier when looking for motorbikes in the parking area with an alarm and increasing the ease and comfort of users in operating motorbikes. From the results of this study it is hoped that the application can make it easier for users to control motorized vehicles such as motorbikes via an Android smartphone.

Abstract

Palm kernel meal (PKM) is a by-product of palm oil production and can be used as an energy source in broiler feed. However, the utilization of PKM in broiler feed has yet to be optimal due to its low nutrient digestibility. This study aims to evaluate the particle size and the levels of PKM in the feed to increase broiler performance. The particle sizes used in this study were 2.5 and 1 mm, and the levels were 5%, 10%, and 15%. An in vivo study was conducted using 1,440 Ross 308 broilers day 0-35, with an average initial weight of 47 grams. The study employed a completely randomized factorial design of 2x3, divided into 6 treatments consisting of (T1) 2.5 mm at 5% PKM as a control, (T2) 1 mm at 5% PKM, (T3) 2.5 mm at 10% PKM, (T4) 1 mm at 10% PKM, (T5) 2.5 mm at 15% PKM, and (T6) 1 mm at 15% PKM on feed. The studied variables were body weight (BW), feed intake (FI), feed conversion ratio (FCR), European production efficiency factor (EPEF), and carcass quality. Increasing PKM levels decreased the pellet durability index of broiler feed. During the starter stage (days 0-21), 1 mm PKM significantly improved FCR (p<0.05) compared to 2.5 mm, although PKM levels did not significantly affect broiler performances. In the finisher stage (days 22-35), 15% of PKM levels negatively impacted FCR and EPEF. Overall, from 0-35 days of age, the best broiler performances showed by treatment T2 with 1 mm particle size and 5% PKM.

Abstract

This study aims to determine the effect of cattle origin and ownership status on the reproductive performance of beef cows in four locations of the Sekolah Peternakan Rakyat (SPR). The study locations include SPR Sungai Lilin (Musi Banyuasin Regency), Mesuji Raya (Ogan Komering Ilir Regency), Pelepat Ilir (Bungo Regency) and Wanaraya (Barito Kuala Regency). The study was conducted through a survey method with direct observation and interviews with SPR members. The variables observed included age at first calving, calving interval, empty period, and service per conception (S/C). The factors analyzed were cattle origin (within or outside the SPR) and ownership status (personal or profit-sharing). The results showed that cattle origin had no significant effect on AFC, CI, DO and S/C. Ownership status had a significant effect on AFC, CI and DO. Recommendation of reproductive optimization strategies based on livestock origin include strengthening breeding stock, standardization of the quality of parents, both from within and outside the SPR area and certification of cattle origin, In contrast, reproductive optimization strategies based on ownership status include reformulation of the profit-sharing model, incentive programs for profit-sharing farmers, development of a gradual ownership scheme.

Abstract

Optimizing dietary energy and amino acid levels is essential for enhancing the performance and cost-efficiency of laying hens. The primary goals were to identify the optimal apparent metabolizable energy (AMEn) and digestible lysine (dLys) levels that maximize hen-day production (HDP) and egg weight (EW) while minimizing feed conversion ratio (FCR) and FC. A total of 150 cages, each housing five hens, were used. Hens with 24 weeks of age were assigned to ten dietary treatments following a central composite design (CCD), with AMEn levels ranging from 2,400 to 2,733 kcal/kg and dLys from 0.42% to 1.02%. The experiment was carried out during peak production (24 to 38 weeks of age). Response surface methodology (RSM) combined with CCD effectively optimized AMEn and dAA levels, providing practical insights for formulating cost-effective diets for commercial laying hens. Dietary dLys significantly influenced HDP and EW, while AMEn affected feed intake (FI). The optimal conditions, determined by the desirability function (DF), were AMEn of 2,660 kcal/kg and dLys of 0.81%, maximizing HDP and EW with minimal FCR and FC. Excluding EW from DF optimization, the best results were achieved at AMEn of 2,623 kcal/kg and dLys of 0.78%.

Abstract

This study evaluated the effects of cassava (Manihot esculenta Crantz) leaves extract (CLE) in drinking water on the performance and health profile of IPB-D1 chickens. Cassava leaves are known to contain bioactive compounds such as flavonoids, tannins, and saponins which have antioxidant and antibacterial properties. These compounds can provide positive effects such as feed efficiency, improving growth performance and health status of chickens by improving the immune system and reducing oxidative stress. Cassava leaves extract acts as a phytogenic additive that can be given in livestock drinking water. This study used 180 IPB-D1 chickens aged 2–8 weeks were randomly assigned to three treatments: CLE0 (control), CLE1 (17 ml/l CLE), and CLE2 (50 ml/l CLE). Parameters observed included growth performance, organ morphometry, hematological profiles, and ileal histology. Data were analyzed using one-way ANOVA and Tukey’s post hoc test (p<0.05). cassava leaves extract supplementation did not adversely affect growth or feed intake. Final body weight and feed conversion ratio (FCR) were not significantly different among the groups. A reduction in leukocyte counts was observed, particularly in the CLE2 group, with a relative increase in heterophils, though values remained within physiological limits. Histological analysis revealed a significant increase in villus surface area in the CLE2 group, followed by CLE1, compared to the control (CLE0), suggesting enhanced intestinal morphology and nutrient absorption potential. Cassava leaves extract can be given in the drinking water of IPB-D1 chickens without disrupting their performance and health profile. These findings indicate that cassava leaves extract can improve gut structure without compromising performance, supporting its application as a safe and beneficial phytogenic additive in poultry diets.
