ABSTRACT Bligon goats, as one of the local livestock resources, had significant potential to improved the welfare of coastal communities in Bantul Regency. The aim of the research was to analyzed the contribution of the viability of the bligon goat business in realizing food resilience, livestock empowerment, and the foundations of national resilience in the coastal areas of Bantul Regency. The research was conducted in Bantul Regency at two kapanewons which represent coastal areas, namely Sanden and Srandakan. This study used an approach to economic conditions over the past year. The calculations carried out included total production, added value, the function of livestock as savings, insurances and fertilizer producers. The average age of farmers in the research location was 53 years 10 months, with an average of 13 years of farming experience and an average of 7 goats. The results of calculating the Net Benefit-Cost Ratio (B/C), Payback Period (PP), and Internal Rate of Return (IRR) in calculating the financial feasibility of the Bligon goat farming business in coastal areas showed that this business was worthy of development. The development of Bligon goat cultivation could be used in efforts to alleviated poverty in the community and supported sustainable economic growth in the coastal areas of Bantul Regency. The sustainability of this economic dimension was expected to make a positive contribution to food resilience and national resilience by encouraging an increase in the number of farmers and goats.

Background and Aim: The impact of exogenous melatonin on the sperm quality of small ruminants is controversial. Therefore, this study aimed to synthesize previous findings on the influence of melatonin injection on sperm quality, steroid hormones, and testicular blood flow in small ruminants. Materials and Methods: Thirty studies were analyzed by computing the raw mean difference (RMD) as the effect size between the control and melatonin treatment groups, using the inverse of the variance for the random-effect model of the method of moments by DerSimonian and Laird. We assessed heterogeneity among studies using Q test. I2 statistic was used to classify the observed heterogeneity. We used Egger’s regression method to indicate publication bias. Results: Melatonin injection (p < 0.05) affected sperm concentration (RMD = 0.42 × 109/mL), morphology (RMD = 2.82%), viability (RMD = 2.83%), acrosome integrity (RMD = 4.26%), and DNA integrity (RMD = 1.09%). Total motility (RMD = 5.62%), progressive motility (RMD = 7.90%), acrosome integrity (RMD = 8.68%), and DNA integrity (RMD = 2.01%) of post-thawed semen in the melatonin-treated group were also increased (p < 0.05). Similarly, treatment with melatonin (p < 0.05) enhanced total motility (RMD = 5.78%), progressive motility (RMD = 5.28%), curvilinear velocity (RMD = 4.09 μm/s), straight-line velocity (RMD = 5.61 μm/s), and average path velocity (RMD = 4.94 μm/s). Testosterone (RMD = 1.02 ng/mL) and estradiol 17-ß levels (RMD = 0.84 pg/mL) were elevated (p < 0.05) in the melatonin-injected group. Melatonin implantation ameliorated testicular blood flow, as indicated by a significant reduction (p < 0.05) in the resistive index (RMD = 0.11) and pulsatility index (RMD = –0.15). Conclusion: Melatonin administration can increase the reproductive performance of small male ruminants.

This study investigates the medicinal properties of Rhodomyrtus tomentosa by extracting its bioactive compounds with n-hexane, ethyl acetate, and ethanol. Ethyl acetate extract had the highest total phenolic content, while hexane extract had the lowest. The ethanol extract had the highest total flavonoid content, with hexane extract having the lowest. Ethanol extract showed the highest antioxidant activity with an IC50 value of 28.61 ± 0.56 μg/mL. Gas Chromatography-Mass Spectrometry profiling identified major compounds like menthol and salicylic acid. Fraction 6, with rhodomyrtone content of 728 μg/mL, had the most dominant rhodomyrtone compound. Higher solvent polarity correlated with higher total phenolic content, total flavonoid content, and antioxidant activity, but lower saponin content. Based on its contents, further studies are needed to investigate its ability to reduce enteric methane, enhance immunity, and adapt to climate change, both in vitro and in vivo in ruminant livestock.

Butterfly pea (Clitoria ternatea L.) is leguminous species that contain high nutritional values. This study aimed to determine the effect of the rate of urea fertilizer and harvest age on the productivity of butterfly pea forage. This research used a split-plot design consisting of urea rates (0, 100, and 200 kg/ha) and harvest ages (30, 45, and 60 days after planting or DAP) with three replications. The variables observed were morphological growth (plant height, stem diameter, number of leaves, and number of branches), and productivity of forage biomass (fresh weight, dry weight, and crude protein). The data obtained were analyzed using ANOVA and the means were separated by using Duncan's Multiple Range Test (DMRT). The interaction between fertilizer rates and harvest ages was shown (p

IP-PBX based communication has become a human need in the era of technology. Some researchers design a wireless telecommunication system based on IP PBX using Raspberry Pi. The previous researches have small network coverage and problematic on the ability of the system to support multiple concurrent connections. Based on these problems, these research aims are to expand the coverage area and increase the number of concurrent calls. This study used Asterisk FreePBX for the media configuration of the servers. The clients: laptops and smartphone devices used Linkin and Bria softphone. The testing was conducted in terms of voice and video services in the form of signal strength, CPU performance of servers, and network performance parameters such as delay, jitter, and packet loss. The results obtained that the CPU performance of the servers for seven calls simultaneously is around 16.9% compared with previous research, at an average of 45%. Based on ETSI standards, the measurement of network performance parameters when communicating between clients outperform than previous research. The clients can communicate well up to 390 meters.

Peternakan adalah salah satu sektor yang berkontribusi dalam peningkatan pemanasan global yang berasal dari kotoran dan ekstraksi hewan. Sektor peternakan menyumbang gas metana (CH4), dinitrogen oksida (N2O), karbon dioksida (CO2), dan amonia yang dapat menimbulkan hujan asam. Tujuan penelitian adalah untuk mengetahui sumbangan emisi Gas Rumah Kaca (GRK) dari sektor peternakan tahun 2016 di provinsi Sulawesi Tengah. Penelitian kajian ini mengunakan metodenya survei lapang dan study literatur untuk memperoleh data sekunder serta data primer tentang populasi ternak di provinsi Sulawesi Tengah yang selanjutnya data ditabulasi dengan mengunakan Sofware ALU Tool untuk menghitung emisi GRK dari sektor peternakan.

Hasil penelitian menujukkan bahwa provinsi Sulawesi Tengah memberikan sumbangan emisi GRK sebesar 633,178 CO2-e Gg/tahun. Kesimpulan dari kajian ini yaitu diantara semua jenis ternak, sapi potong merupakan kontributor utama dalam penyumbang emisi GRK dalam bentuk Fermentasi Enterik CH4 483,9 (Gg CO2e) yaitu sebanyak 76,42%, diikuti oleh kambing dalam bentuk N2O sebesar 108,428 (Gg CO2e) atau setara dengan 17,12 %.

This series of research activities are in the form of a routing simulation using the LEACH protocol as a cluster-based mechanism method that can improve Network Lifetime in the Wireless Sensor Network protocol, using the Network Simulator 2 application device that describes data transmission, remaining nodes, and energy used. Determination of the performance and power consumption of the wireless sensor network by testing scenario one to scenario five due to the influence of the cluster to be applied, such as scenario 1 using 1 cluster (C1) consumes an average of the energy of 0.155 joules and the data sent or obtained is 72,848 bytes. Barriers or disruptions to the clusterhead affect the performance of LEACH, so there is a need for criteria or conditions to determine which nodes should be used as clusterhead.
