The utilization of crop residue as a feed is very important because the arable land area is relatively limited. The study was aimed to examine the influence of adoption of crop-residue product as a feed. The research was conducted in Maros District by using survey methods from March to August 2015. The number of respondents was 96 farmers scattered throughout the Districts of Bantimurung and Camba as centers of rice, corn plant, and cattle productions. Questionnaires were used to collect data conducted by a trained enumerator. Survey was arranged using a logistic regression model to identify socio economic factors influencing the adoption of crop residue as a feed. Work perception (X2), contact with extension workers (X4), rice cultivated areas (X5), the number of livestock (X6), subjective norm (X7), and difficulty (X8) were socio-economic variables influencing the adoption of crop residue as a feed. However, the variables age (X1), farmer experiences (X3), and the number of family members (X9) had no effect on the adoption of this technology. In conclusion, extension workers play an important role in increasing the adoption of technology by using rice and corn straws as a feed. Likewise, not only the number of livestocks, but also the good perception of the farmers increased along with the increase of feed availability, such as utilization of rice and corn straws.
Abstract:The effects of two levels of manure application (184 and 275 kg N ha −1 year −1 ) on herbage yield, quality, and wintering ability during the cropping of a dwarf genotype of late-heading (DL) Napiergrass (Pennisetum purpureum Schumach) oversown with Italian ryegrass (IR; Lolium multiflorum Lam.) were examined and compared with chemical fertilizer application (234 kg N ha −1 year −1 ) for 4 years to determine a sustainable and environmentally harmonized herbage production in a hilly area (340 m above sea level). No significant (p > 0.05) differences in growth attributes of plant height, tiller density, percentage of leaf blade, or dry matter yield appeared in either DL Napiergrass or IR among moderate levels (184-275 kg N ha −1 year −1 ) of manure and chemical fertilizer treatments. IR exhibited no significant detrimental effect on spring regrowth of DL Napiergrass, which showed a high wintering ability in all treatments. In vitro dry matter digestibility of DL Napiergrass tended to increase with increasing manure application, especially at the first defoliation in the first three years. Manure application improved soil chemical properties and total nitrogen and carbon content. The results suggested that the lower rate of manure application of 184 kg nitrogen ha −1 year −1 would be suitable, which would be a good substitute for chemical fertilizer application with an equilibrium nitrogen budget for sustainable DL Napiergrass and IR cropping in the hilly region of southern Kyushu.
Salah satu upaya yang dapat dilakukan untuk meningkatkan produktivitas ternak adalah dengan melakukan perbaikan nutrisi serta lingkungan ternak. Kondisi kekurangan pakan dan produksi limbah ternak yang besar merupakan salah satu permasalahan yang dihadapi oleh mitra. Perguruan tinggi sebagai salah wadah yang bertanggungjawab dalam memberikan solusi merasa perlu melakukan upaya sosialisasi dan transfer teknologi khususnya terkait dengan permasalahan pakan dan limbah ternak. Program pengabdian masyarakat ini bertujuan untuk memberikan pembelajaran bagi mitra kelompok tani-ternak terkait dengan terapan teknologi dalam memproduksi pakan fermentasi sebagai cadangan pakan pada musim paceklik serta pengolahan limbah ternak khususnya urin menjadi pupuk organik cair (POC). Kegiatan yang dilakukan merupakan wujud kepedulian perguruan tinggi terhadap kondisi dan produktivitas usaha peternakan rakyat yang semakin menurun. Kegiatan terapan teknologi telah dilaksanakan di Desa Balangtanaya, Kec. Polombangkeng Utara, Kab.Takalar. Kelompok mitra yang terlibat adalah kelompok tani-ternak “Sikatutui”. Beberapa paket teknologi yang telah didiseminasikan antara lain paket : 1) teknologi amoniasi jerami, 2) teknologi pakan silase komplit fermentasi, 3) teknologi pembuatan mikroorganisme lokal (MOL) serta 4) teknologi pembuatan Urea Molasses Block (UMB). Metode terapan teknologi dilakukan melalui kegiatan pelatihan dalam bentuk tatap muka dan praktek. Selanjutnya dilakukan upaya pendampingan dan monitoring. Hasil pelaksanaan kegiatan menunjukkan bahwa kegiatan penerapan teknologi memberikan dampak yang sangat positif bagi mitra dalam meningkatkan kapasitas khususnya terkait dengan kemampuan dalam mengolah dan memproduksi pakan fermentasi serta mengolah limbah ternak menjadi produk komersial.

This study utilized Urea Multiplenutrient Molasses Block (UMMB) based on 40% of Indigofera flour to determine daily gain and performance of postpartum Bali Cattle. The parameters of the study were daily gain, chest depth, body length, and withers height. The UMMB consisting of rice bran, urea, coconut cake meal, shrimp waste meal, molasses, mineral, Indigofera flour, salt, and cement as an adhesive. This study was divided into two paddocks where each paddock consisted of 10 head an-estrus postpartum Bali Cattle. Subsequently, each paddock was arranged by different treatment consisted of control (without any treatments) and additional feed supplement of UMMB. The mean values of each parameter were compared by T-Test. The result revealed that the additional feed supplement of UMMB had significant effect on average daily gain (0,8 kg head day ) compared to the control treatment (0.2 kg head day ). The treatments had significant effect on chest circumference (0.2 ± 0.05 vs 0.3 ± 0.02 cm head day ) and body length (0.04 ± 0.01 vs 0.14 ± 0.05 cm head day ). In contrary, neither control nor additional feed supplement had no significantly effect (P = 0.55) to shoulder height of postpartum Bali Cattle (0.13 ± 0.03 vs 0.18 ± 0.06 cm head day ). Daily gain of an-estrus post-partum Bali cattle tended to be high by feed supplement of UMMB. Therefore, UMMB was appropriate for ruminant diet as a feed supplement.
