Judul: Analysis of Income and Production Efficiency of Dairy Cattle Farming Business in Baturraden District, Banyumas Regency
Abstrak: FRIDO AGENG PRIAMBODO. Analisis Pendapatan dan Efisiensi Produksi Usaha Peternakan Sapi Perah di Kecamatan Baturraden Kabupaten Banyumas. Dibimbing oleh YUSMAN SYAUKAT. Kecamatan Baturraden merupakan salah satu daerah penghasil susu sapi terbesar di Kabupaten Banyumas dengan total produksi sebanyak 1.626 ton pada tahun 2022. Akan tetapi, Baturraden merupakan kecamatan dengan produktivitas terendah jika dibandingkan dengan empat kecamatan lainnya. Berdasarkan hal tersebut tujuan dari penelitian ini yaitu: 1) menganalisis pendapatan usaha peternakan sapi perah di Kecamatan Baturraden; 2) menganalisis faktor-faktor yang memengaruhi produksi usaha peternakan sapi perah di Kecamatan Baturraden; dan 3) Menganalisis efisiensi teknis pada usaha peternakan sapi perah di Kecamatan Baturraden. Metode yang digunakan dalam penelitian ini adalah regresi linear berganda dengan metode Ordinary Least Squares (OLS), analisis pendapatan dengan menggunakan R/C ratio, dan metode Stochastic Frontier untuk mengetahui efisiensi teknis. Hasil penelitian menunjukkan bahwa produksi susu sapi perah di Baturraden masih menguntungkan karena memiliki nilai R/C ratio lebih dari satu. Faktor – faktor yang berpengaruh signifikan yaitu pakan hijauan, pakan konsentrat, dan pakan ampas tahu. Produksi susu sapi perah di Baturraden secara teknis sudah cukup efisien namun efisiensi ini masih bisa ditingkatkan lagi., FRIDO AGENG PRIAMBODO. Analysis of Income and Production Efficiency of Dairy Cattle Farming Business in Baturraden District, Banyumas Regency. Supervised by YUSMAN SYAUKAT. Baturraden is one of the largest cow milk producing areas in Banyumas Regency with a total production of 1,626 tons in 2022. However, Baturraden is the sub-district with the lowest productivity compared to the other four sub-districts. Based on this, the objectives of this study are: 1) to analyze the income of dairy farming businesses in Baturraden Subdistrict; 2) to analyze the factors that affect the production of dairy farming businesses in Baturraden Subdistrict, and 3) to analyze the technical efficiency of dairy farming businesses in Baturraden Subdistrict. The method used in this research is multiple linear regression with Ordinary Least Squares (OLS) method, income analysis using R/C ratio, and Stochastic Frontier method to determine technical efficiency. The results showed that dairy milk production in Baturraden is still profitable because it has an R/C ratio value of more than one. Factors that have a significant effect are forage feed, concentrate feed, and tofu dregs feed. Dairy milk production in Baturraden District is technically efficient enough but this efficiency can still be.

Judul: Production efficiency analysis of dairy farm in pondok ranggon cipayung sub-district east jakarta
Abstrak: Permintaan susu sapi perah di Indonesia meningkat setiap tahunnya, namun produksinya belum memenuhi kebutuhan nasional. Peternakan sapi perah Pondok Ranggon merupakan tempat penyedia susu sapi untuk warga DKI Jakarta. Peternakan sapi perah Pondok Ranggon memiliki peranan penting dalam peningkatan produksi susu di Indonesia. Tujuan penelitian ini adalah untuk: (1) menganalisis faktor-faktor yang mempengaruhi produksi susu sapi perah, (2) menganalisis efisiensi produksi susu sapi perah, (3) menganalisis pendapatan usaha peternakan sapi perah di Pondok Ranggon. Faktor produksi susu sapi perah dianalisis menggunakan fungsi produksi Cobb-Douglas dan parameter diestimasi dengan metode Ordinary Least Squares (OLS), analisis efisiensi produksi dilakukan dengan menggunakan Nilai Produk Marginal (NPM) sama dengan harga faktor produksi, dan pendapatan usaha peternakan dilakukan dengan analisis pendapatan. Faktor-faktor yang mempengaruhi produksi susu sapi perah adalah pakan hijauan, ampas tahu, dan tenaga kerja. Nilai efisiensi masing-masing faktor produksi tidak sama dengan satu, berarti bahwa penggunanaan faktor produksi belum efisien. Nilai R/C ratio yang lebih besar dari satu, sehingga analisis pendapatan menunjukkan bahwa usaha peternakan sapi perah menguntungkan., The demand for milk of dairy cattle in Indonesia increasing every year, but the production has not fulfill the national needs. Pondok Ranggon dairy farm is a supplier milk to DKI Jakarta people. Pondok Ranggon dairy farm has an important role in improvement milk production in Indonesia. The purposes of the study were to: (1) analyze the affecting factors for the production milk of dairy cattle, (2) analyze the production efficiency of milk of dairy cattle, (3) analyze the income of Pondok Ranggon dairy farm. The production factor of milk of dairy cattle was using the production function of Cobb-Douglas analysis and estimated parameter was using Ordinary Least Squares (OLS) method, analysis production efficiency was using Value of Marginal Product (VMP) equal to production factor prices, and income of dairy farm analyze using income analysis. The affecting factors of production milk of dairy cattle is grass, tofu waste, and labors. The value of efficiency of each production factor is not equal to one, means that the use of production function have not been efficient. The value of R/C ratio is greater than one, so that the income analysis shows for dairy farm is profitable.

Judul: Hydroxyapatite-Chitosan Composite Coating on Stainless Steel 316 to Improve Corrosion Resistance
Abstrak: Metals that were used in bone implantation should have good corrosion resistance that were not easily corroded when implanted into the body. Metal corrosion resistance of stainless steel 316 can be enhanced through the metal coating by hydroxyapatite-chitosan composite with composition ratio of hydroxyapatite (gram) and chitosan 3% (mL) 0.2:0, 0.2:0.1, 0.2:0.5, 0.2:1.0, and 0.2:1.5. Besides improving the corrosion resistance of metal, the presence of chitosan also maintain the position of hydroxyapatite on metal surfaces. Corrosion resistance increases with increasing amount of chitosan added and the best composition of hydroxyapatite-chitosan composite was 0.2:1.0.
