The study aimed to evaluate zinc sulfate and Zn-Cu isoleusinat supplementation with concentrates on rumen fermentation of Bali cattle. The experiment design used randomized block design. The animal randomized, assigned into four groups of treatment diet. They were T0 = Ammoniated kume grass standing hay + concentrate (60:40); T1 = T0 + 150 mg ZnSO4/kg DM concentrate + 1 % Zn-Cu isoleusinate; T2 = T0 + 150 mg ZnSO4/kg DM concentrate + 2 % Zn-Cu isoleusinate; and T3 = T0 + 150 mg ZnSO4/kg DM concentrate + 3 % Zn-Cu isoleusinate. Supplementation zinc sulfate and Zn-Cu isoleusinate in the concentrate did not increase significantly NH3 concentration, total VFA, acetate, and butyrate production. However, supplementation zinc sulfate and Zn-Cu isoleusinate increase significantly (P<0.01) propionate production, decrease propionate and acetate ratio. The best of rumen fermentation achieved at level of ZnSO4 and Zn-Cu isoleusinate supplementation 150 mg ZnSO4 kg−1. Concentrate and 2% Zn-Cu isoleusinat kg−1 diet. It can concluded supplementing Bali cattle with combination of 1.5% lemuru oil, 150 mg ZnSO4/kg DM concentrate and 2% Zn-Cu isoleucinate / kg DM ration had increased NH3, VFA concentrations, C3 production, but decreased C2 and C2/C3 ratio which positively correlated with decrease in CH4 gas production.

Rice is a major issue in food security and independence because more than 90% of the population in Indonesia is highly dependent on rice. The need for rice is increasing as the population exponentially grows, but the area of paddy fields is decreasing. In the era of the industrial revolution 4.0, one of the goals was to increase the knowledge and skills of the farming community. In this connection, the attention of the government and the community is focused on increasing rice production through various innovations and the use of rice intensification technology based on the use of organic fertilizer. Innovation use of ABG (Amazing Bio Growth) biostimulant fertilizer with a target of achieving 8-15 tons/ha of rice compared to conventional 3-4 tons/ha. Efforts to increase rice production with the technology "Organic-Based Aerobic Controlled Rice Intensification (IPAT-BO)" is the answer to support the industrial revolution 4.0 in agriculture. The success of IPAT-BO technology in irrigated rice fields and rainfed rice fields apparently can also be applied in rice fields that use live water or water from bore wells on dry land in semi-arid tropical ecosystems in NTT. IPAT-BO technology applied to farmers in Bipolo Village, Sulamu and Babau Districts, East Kupang District, Kupang Regency using limited water along with drainage arrangements on dry land, grain production can reach 6-8 tons/ha. The successful application of this technology is highly dependent on the development of the root system, biodiversity, and balance in the supply of nutrientsABSTRAK:Beras merupakan isu utama dalam ketahanan dan kemandirian pangan karena lebih dari 90% penduduk di Indonesia sangat tergantung pada beras. Kebutuhan beras semakin meningkat seiring pertumbuhan eksponensial penduduk, namun  luas lahan sawah semakin berkurang. Di era revolusi industri 4.0 salah satu sasarannya adalah peningkatan pengetahuan dan keterampilan masyarakat tani. Dalam kaitannya dengan hal tersebut, perhatian pemerintah dan masyarakat difokuskan untuk meningkatkan produksi padi melalui berbagai inovasi dan penggunaan teknologi intensifikasi padi berbasis pada penggunaan pupuk organik. Terobosan penggunaan biostimulan pupuk ABG (Amazing Bio Growth) dengan target pencapaian produksi padi 8-15 ton/ha dibanding dengan produksi 3-4 ton/ha secara konvensional. Upaya peningkatan produksi padi dengan teknologi “Intensifikasi Padi Aerob Terkendali Berbasis Organik (IPAT-BO)” merupakan jawaban untuk mendukung revolusi industri 4.0 di bidang pertanian.  Keberhasilan teknologi IPAT-BO di lahan sawah irigasi dan sawah tadah hujan ternyata juga dapat diterapkan di lahan sawah yang menggunakan air hidup atau air dari sumur bor pada lahan kering di ekosistem tropis semi kering di NTT. Teknologi IPAT-BO yang diterapkan pada petani di Desa Bipolo, Kecamatan Sulamu dan Babau, Kecamatan Kupang Timur, Kabupaten Kupang dengan menggunakan air secara terbatas disertai pengaturan drainase di lahan kering, produksi gabahnya dapat mencapai 6-8 ton/ha. Keberhasilan penerapan teknologi tersebut sangat tergantung pada perkembangan sistem perakaran, keanekaragaman hayati dan keseimbangan pasokan nutrisi.

This study was done to examine the chemical quality of rumen fermentation and in vitro digestibility of complete feed based on silage sorghum-Clitoria ternatea with the level of addition of concentrates. The Complete Randomized Disgn was used in this study with four treatments and four replications. The treatments were T1: Sorghum silage – Clitoria ternatea without concentrate; T2: T1 + 10% concentrate; T3: T1 + 20% concentrate and T4: T1 + 30% concentrate. The concentrate contains 150 mg ZnSO4/kg DM and 2% Zn-Cu isoleucine/kg DM ration. The parameters studied were 1). chemical quality; 2) production NH3 and VFA in vitro; 3) digestibility of DM and OM (DDM and DOM) in vitro. The results showed that the treatment could be increased the crude protein content and the increase occurred linearly, but decrease the crude fiber content such as NDF, ADF, cellulose, and lignin, while the content of hamicellulose had no efeect. The treatments also had no effect on the pH value, decreased VFA production, and increased NH3 production in vitro, but the highest contribution of protein and crude fiber to NH3 and VFA production was at the level addition of T1 treatment. Treatments had an effect on increasing DDM and DOM in vitro and the highest was at the level of addition of 10% concentrate (T1). It could be concluded that the protein and crude fiber content gave a highest contribution to the production of NH3, VFA, DDM and DOM in vitro at 10% concentrate level.

Abstract:The study aimed to evaluate the effects of substitution of corn meal from concentrate of plus-complete feed (PCF) with fermented cocoa pod (FCP) on growth of the young male Bali Cattle. Fifteen young male Bali Cattles were randomly assigned into five groups for the substitutions of corn meal from the PCF by FCP treatments i.e 0, 25, 50, 75 and 100 % which each group was replicated by three subgroups. The pods were fermented with yeast Aspergillus niger that had been activated by combinations of sugar, urea, NPK fertilizers, and various levels of ZnSO 4 and Zn-Cu isoleusinate. The best FCP, that produced NH 3 and VFA in in vitro experiment, was used in the study. The results showed that substitutions of corn meal from the PCF by 100% FCP decreased signifikantly (P<0.01) Zn and Cu status, energy and N retention, and body weight gain of the young male Bali Cattles. However, the substitutions of corn meal with 0 %, 25% and 50% FCPs, those values did not decrease significant. Despite of corn meal substitutions of PCF by FCP did not decrease significantly plasma glucose and protein consumption, but substitution by FCP between of 0 % and 25 % did not decrease significantly protein consumption. In conclusion: the substitution of corn meal from the PCF by the FCP at the level up to 50% can be applied without disturbance the growth of the young male Bali Cattle.
