Judul: Good Housing and Good Management Using the Analytical Hierarchy Process in Jakarta People's Dairy Farms
Abstrak: Pondok Ranggon merupakan salah satu kawasan peternakan sapi perah yang berada di Jakarta. Aspek kandang peralatan dan pengelolaan merupakan faktor dalam good dairy farming practices (GDFP). Penelitian ini bertujuan mengevaluasi kriteria penentu yang paling prioritas pada Good Housing dan Good Management di peternakan sapi perah rakyat Pondok Ranggon Jakarta. Penelitian dilakukan dengan pengumpulan data primer yang diperoleh melalui wawancara kuisioner Good Housing dan Good Management berdasarkan panduan GDFP dan data sekunder diperoleh dari keterangan peternak dan studi pustaka. Data dianalisis menggunakan metode analisis deskriptif dan Analytical Hierarchy Process (AHP). Hasil GDFP pada Good Housing dan Good Management di peternakan sapi perah Pondok Ranggon tergolong baik dengan nilai performa 86,25% dan 85,31%. Nilai gabungan pengamatan dan vektor prioritas pada kedua aspek tersebut tergolong baik dengan nilai 85,31% pada aspek kandang dan peralatan dan 84,75% pada aspek pengelolaan. Prioritas utama pada aspek kandang dan peralatan adalah konstruksi kandang sedangkan pada aspek pengelolaan adalah pengeringan sapi laktasi., Pondok Ranggon is one of the dairy farming areas in Jakarta. Aspects of cage equipment and management are factors in good dairy farming practices (GDFP). This study aims to evaluate the criteria for determining the most priority on Good Housing and Good Management in the Pondok Ranggon people's dairy farm, Jakarta. The research was carried out by collecting primary data obtained through interviews with Good Housing and Good Management questionnaires based on GDFP guidelines and secondary data obtained from information from breeders and literature studies. Data were analyzed using descriptive analysis methods and Analytical Hierarchy Process (AHP). GDFP results on Good Housing and Good Management at the Pondok Ranggon dairy farm are classified as good with performance values of 86,25% and 85,31%. The combined value of observations and priority vectors for both aspects is classified as good with a score of 85,31% for the cage and equipment aspect and 84,75% for the management aspect. The main priority for the housing and equipment aspect is the construction of the stable, while the management aspect is drying the lactating cows.

Judul: Animal Welfare dan Good Housing Menggunakan Analytical Hierarchy Process pada Peternakan Sapi Perah Rakyat KPSBU Lembang.
Abstrak: Peningkatan produksi susu sapi perah dapat diupayakan dengan Good Dairy Farming Practices (GDFP). Salah satu aspek penentu GDFP adalah Animal Welfare dan Good Housing. Penerapan Animal Welfare dan Good Housing yang baik dapat meningkatkan produktivitas sapi perah. Penelitian ini bertujuan mengevaluasi dan menganalisis kriteria penentu yang paling berpengaruh dalam GDFP aspek Animal Welfare dan Good Housing dengan menggunakan Analytical Hierarchy Process (AHP). Metode yang digunakan yaitu metode survei dan wawancara langsung kepada 10 peternak di Manoko dan 10 peternak di Cisaroni yang merupakan anggota Koperasi Peternak Sapi Perah Bandung Utara (KPSBU) serta 4 orang ahli yang terdiri dari akademisi, praktisi, dan pemerintah. Hasil penelitian menunjukkan aspek Animal Welfare lebih penting daripada Good Housing. Kriteria penentu tertinggi berdasarkan nilai gabungan pengamatan dan vektor prioritas dari Animal Welfare adalah bebas dari lapar dan haus sebesar 18,98% dengan bobot AHP 0,276, sedangkan dari Good Housing adalah peralatan susu 14,15% dengan bobot AHP 0,149., Increasing the milk production of dairy cows can be attempted with Good Dairy Farming Practices (GDFP). One of the defining aspects of GDFP is Animal Welfare and Good Housing. Good application of Animal Welfare and Good Housing can increase the productivity of dairy cows. This study aims to evaluate and analyze the most influential determining criteria in GDFP aspects of Animal Welfare and Good Housing by using the Analytical Hierarchy Process (AHP). The method used is a survey method and interviews with 10 farmers in Manoko and 10 farmers in Cisaroni who are members of the North Bandung Dairy Farmers Cooperative (KPSBU) and 4 experts consisting of academics, practitioner, and the government. The results of the research show that the Animal Welfare aspect is more important than Good Housing. The highest determining criterion based on the combined observation value and priority vectors from Animal Welfare is free from hunger and thirst 18,98% with an AHP weight of 0,276, while from Good Housing is milk equipment 14,15% with an AHP weight of 0,149.

Judul: Metrik Einstein (Anti-) Self-Dual Berdimensi Empat dengan Metode Cartan
Abstrak: Gravitational field equation can be formulated in differential forms (differential geometry), which describes gravity as a manifestation of the curvature of space-time. Curvature of space-time is characterized by a metric that satisfies the gravitational field equation. With differential forms it can be formulated the (anti-) self-dual Einstein equation, which is a modification of the Cartan structure in (anti-) self-dual basis. Calculation of (anti-) self-dual metric with (anti-) self-dual Einstein equation is simpler than the calculation using Christoffel symbols.
