Abstract

Indonesia is the largest exporter of palm oil  with 85 - 90% of the world's total palm oil production. The consumption of palm oil in Indonesia  is increasing every year, thus the waste are also  increase. Waste cooking oil contains carcinogenic substances which causes various diseases. Biodiesel is an environmentally friendly substitute fuel for diesel made from vegetable oil as raw material. Used cooking oil can be used as raw material for biodiesel production, but it needs to be purified before further processing. Chicken egg shell contains 90% of CaCO3 can be used as a biosorbent of used cooking oil. Durian skin contains 50% - 60% of cellulose also has the potential as a biosorbent. This research was conducted to investigated the effectiveness of the combination of chicken egg shell biosorbent with durian skin for the purification process of used cooking oil as a raw material of biodiesel. Biosorbent was produced by carbonization process in a furnace at a temperature of 550oC for durian skin and 9000C for chicken egg shells. The results show that the acid number of used cooking oil has met the parameters of the SNI 3741: 2013, namely 0.43 mgKOH / gr and FFA levels of 0.0024% with a yield of 62.76%. The purified cooking oil was then continued with the transesterification process to produced biodiesel. The biodiesel obtained had the cetane numbers B100 of 33.8 and B30 of 45.2.

Abstract

Ketosis, mastitis, metritis, and LDA are diseases that often occur during the first two weeks of lactation and cause significant economic loss. The relationships between ketosis, mastitis, metritis, LDA, and several combinations of diseases and the first artificial insemination were discussed. This study aimed to describe the effect of diseases diagnosed during the postpartum period on the success of artificial insemination. This study was conducted using an observational cross-sectional approach. A total of 341 data samples were obtained, which consisted of 103 cattle without disease, 107 cattle diagnosed with ketosis, 51 cattle diagnosed with metritis, 5 cattle diagnosed with LDA, 20 cattle diagnosed with a combination of ketosis and mastitis, 20 cattle diagnosed with a combination of ketosis and metritis, and 6 cattle diagnosed with a combination of mastitis and metritis. Data analysis was carried out using bivariate analysis and tested using the chi-square test. The P values for ketosis, mastitis, metritis, LDA, ketosis-mastitis, ketosis-metritis, and mastitis-metritis were 0.756, 0.099, 0.972, 0.261, 0.276, 0.276, and 0.450, respectively. This study suggested that a history of disease during the postpartum period did not significantly affect cattle first artificial insemination.

Abstract

In Indonesia, only a limited number of logistics providers have obtained halal certification, even though halal logistics plays a crucial role in preserving product integrity and preventing cross-contamination. This study analyzes the implementation of halal logistics by identifying key variables that influence the availability of halal products in the Indonesian market. Using a quantitative research approach, data were collected through surveys of 108 companies, including 35 logistics service providers and 73 halal-certified MSMEs, as well as semi-structured interviews with logistics service providers and MSME business actors in the food sector. The data were analyzed using multiple regression analysis to determine the most influential factors affecting halal product availability. The findings indicate that halal product information availability, consistent worker training, and corporate environmental responsibility are the primary variables influencing halal product availability. These insights provide a foundation for policymakers to develop regulations that strengthen halal logistics while enabling logistics providers and MSMEs to allocate resources more effectively to maintain halal product availability in the market. As one of the few studies examining halal logistics in Indonesia’s food sector, this research contributes to the broader discourse on halal supply chain management and policy development. This study emphasizes the need for stronger stakeholder collaboration to enhance halal logistics sustainability in Indonesia.

Feline Leukemia Virus (FeLV) is one of the major causes of death in cats. A 4-year-old domestic cat weighing 2 kg presented with decreased appetite, weakness, sneezing, and nasal discharge. Physical examination revealed gingivitis accompanied by ulcers in the mouth and pale mucous membranes. Further diagnostic tests included hematology examination, blood chemistry examination, and the FeLV test kit. The results of hematology and blood chemistry examinations reported that the animal had leukocytosis, neutrophilia, thrombocytopenia, hypochromic macrocytic anemia, hyperproteinemia, hyperglobulinemia, decreased A/G ratio, hyperamylasemia, hyperbilirubinemia, and azotemia. Rapid test (kit) examination showed a positive result for FeLV. Based on the diagnostic results, the initial diagnosis was suspected Feline leukemia virus (FeLV) with an infausta prognosis. The treatment included antibiotics Amoxicillin at 18 mg/kgBW, Diphenhydramine HCl 1 mg/kgBW, Ornipural® 0.2 ml/kgBW, Kenalog® 1 mg/kgBW, Hematovit® dose 0.4 ml/kgBW, and supplements in the form of Vitamin C 0.5 ml/day and Fufang® 1 ml/kgBW. Despite the treatment, the cat’s condition did not improve and it succumbed on the sixth day of treatment.

Abstract

A five-year-old female Pomeranian dog presented with vomiting, restlessness, decreased appetite, and vaginal discharge. The physical examination revealed yellowish to brownish purulent vaginal discharge with an unpleasant smell. The X-ray image showed an enlarged uterus, while the hematology results revealed hypochromic normocytic anemia, neutrophilia, lymphopenia, and thrombocytopenia. The blood chemistry test results showed abnormalities, including elevated levels of alkaline phosphatase levels (ALP) and cholesterol as well as decreased amylase levels. Based on the anamnesis, clinical findings, physical examination, and supporting examinations, it was concluded that the dog was diagnosed with open cervix pyometra. The dog was treated with oxytocin hormone at a dose of 0.5 IU/kg BW, methylergometrine at a dose of 0.125 mg/dog, enrofloxacin at a dose of 5 mg/kg BW, carprofen at a dose of 2.5 mg/kg BW, cyproheptadine at a dose of 0.5 mg/kg BW, ranitidine at a dose of 3.5 mg/kg BW, ondansetron at a dose of 1 mg/kg BW, glyseryl guaiacolate at a dose of 20 mg/kg BW, ambroxol HCl at a dose of 2 mg/kg BW, Fufang® at adose of  1 ml, Sangobion® at a dose of 100 mg/dog, Maxbiotik® at a dose of 66 mg, and Transfer Factor Plus® at a dose of 20 mg. The treatment resulted in an improvement in the animal's condition as evidenced by the absence of nasal and vaginal discharges and vomiting, as well as a stool consistency of two out of five.

Abstract

Penyakit Mulut dan Kuku (PMK) disebabkan oleh virus dari famili Picornaviridae yang menyerang hewan berkuku belah dengan tingkat morbiditas yang tinggi dan bersifat akut. Tujuan penelitian ini adalah untuk mengkaji pengaruh infeksi alami PMK terhadap nilai hematologi sapi Madura pada fase infeksi dan fase recovery. Sebanyak 15 ekor sapi Madura yang sudah didiagnosis menderita PMK dengan gejala klinis berupa sialorrhea, lameness, recumbency, vesikel dan erosi pada bagian gingiva, dental pad dan lidah, serta lesi pada area interdigital kaki digunakan dalam penelitian ini. Proses pengambilan sampel darah sebanyak 3 ml melalui vena coccygea dengan menggunakan vacutainer (BD, Franklin, USA) yang mengandung antikoagulan EDTA (Ethylene Diamine Tetra Acetic Acid). Pengambilan sampel darah dilakukan sebanyak dua kali yaitu pada fase infeksi (antara hari ke-3 sampai hari ke-7) dan pada fase recovery (hari ke-30 post infeksi). Sampel yang sudah dikoleksi selanjutnya dilakukan analisis parameter hematologi menggunakan Veterinary Hematology Analyzer Rayto 7600, sedangkan analisis data hasil pemeriksaan menggunakan IBM SPSS Statistics. Hasil penelitian menunjukkan bahwa nilai leukosit, limfosit, hemoglobin, hematokrit, MCHC, MCV, RDW-CV, trombosit, MPV, PDW, PCT antara stadium infeksi dan recovery berbeda signifikan (p<0,05). Pada fase infeksi dilaporkan terjadi leukositosis, granulositosis, limfositosis, serta penurunan hemoglobin, MCHC, MCV, RDW-SD, PDW, dan P-LCR. Sedangkan pada fase recovery dilaporkan nilai leukosit dan granulosit masih diatas normal, sementara itu parameter lain sudah pada level normal. Disimpulkan bahwa infeksi alami PMK pada sapi Madura menyebabkan perbedaan nilai hematologi yang signifikan antara fase infeksi dan recovery.
