Judul: Analisis Kelayakan Usahaternak Sapi Perah pada Alda Alya Dairy Farm di Kecamatan Tambun Selatan, Kabupaten Bekasi
Abstrak: The availability of national milk has not been able to meet the needs of milk, only about 21 persen in 2013. While existing market potential was quite large with the increasing number of population. Alda Alya Dairy Farm took that chance and opened dairy farming on 2007. However, the investments made in the business requires substantial capital investment and a long payback. Therefore,it was necessary to conduct research on the feasibility analysis of dairy cattle farming. The feasibility analysis of dairy farming conducted on the feasibility of financial and nonfinancial. Nonfinancial feasibility was done based on market aspects, technical aspects, management and legal aspects, and social, economic, and environmental aspects. While the financial feasibility was measured by investment criteria such as NPV, IRR, Net B/C, Gross B/C, and Payback Period. In addition, there was a switching value analysis on components of lower sales volume and an increase in feed costs. Based on the results of the analysis of both financial and nonfinancial feasibility, Alda Alya Dairy Farm is feasible to run.And based on switching value analysis Alda Alya Dairy Farm more sensitive to components of lower sales volume.

Judul: Determination  of  marketing  strategy  priority  of  dairy milk at alda alya dairy farm  sumber jaya village, bekasi regency
Abstrak: Alda Alya Dairy Farm merupakan salah satu produsen susu sapi di Kabupaten Bekasi. Produk susu sapi yang dihasilkan telah dijual ke konsumen, pengecer, koperasi susu, dan Industri Pengolahan Susu. Saat ini, Alda Alya Dairy Farm mengalami beberapa permasalahan seperti fluktuasi penjualan dan keterbatasan sumberdaya manusia. Tujuan dari penelitian ini adalah untuk mengidentifikasi dan menganalisis bauran pemasaran susu sapi yang telah diterapkan Alda Alya Dairy Farm dan menentukan prioritas bauran pemasaran susu sapi di Alda Alya Dairy Farm. Metode Proses Hirarki Analitik (PHA) digunakan dalam penelitian untuk memilih prioritas strategi pemasaran berdasarkan keputusan pihak internal. Hasil analisis PHA menunjukkan bahwa bauran pemasaran yang menjadi prioritas secara berturut-turut adalah produk, promosi, distribusi, dan harga. Beberapa sub bauran telah ditentukan sebagai prioritas dalam bauran pemasaran. Sub bauran tersebut adalah kualitas, media sosial, distribusi tidak langsung, dan diskriminasi harga., Alda Alya Dairy Farm is one of the dairy milk producers in Bekasi Regency. Its product has been sold to consumers, retailers, dairy cooperatives, and the Dairy Processing Industry. Recently, Alda Alya Dairy Farm is facing some problems such as sales fluctuations and limitation of human resources. The purpose of this study is to identify and analyze the marketing mix of dairy milk that has been applied by Alda Alya Dairy Farm and prioritizing marketing mix for Alda Alya Dairy Farm. Analytical Hierarchy Process (AHP) was used as the method to solve the problems through the selection of several priorities. Result showed that the order of marketing mix priority that has been chosen by internal parties are : product, promotion, distribution, and price. Also, the ultimate goal can be determined by several criteria of marketing mix. Those criteria are quality, social media, indirect distribution, and price discrimination.

Judul: Kruskal Coordinates in 4+1 Dimensional Schwarzschild  Spacetime Geometry
Abstrak: Koordinat Kruskal adalah hasil ekstensi maksimal dari koordinatSchwarzschild yang menimbulkan interpretasi baru tentang keberadaan wormhole. Secara teori, wormhole adalah struktur yang menghubungkan dua titik berbeda dalam ruangwaktu. Namun, ukuran wormhole terlalu kecil untuk dapat dilalui dan tidak stabil sehingga mudah runtuh. Penelitian ini bertujuan mendapatkan solusi koordinat Kruskal untuk geometri Scwarzschild pada dimensi yang lebih tinggi yang dapat berguna untuk menganalisis kestabilan wormhole. Penelitian ini dilakukan melalui penambahan dimensi ruang dari 3+1 dimensi menjadi 4+1 dimensi untuk mendapatkan geometri Schwarzschild, koordinat Eddington-Finkelstein, dan koordinat Kruskal dengan memanfaatkan gerak radial foton. Hasil akhirnya, solusi geometri ruangwaktu Schwarzschild dalam koordinat Kruskal dapat dibentuk dan diilustrasikan dalam diagram Kruskal. Diagram tersebut menunjukan sebuah black hole, white hole, dan dua alam semesta yang dihubungkan oleh wormhole., The Kruskal coordinates are the maximal extension of the Schwarzschild coordinates which give rise to new interpretations of the existence of wormholes. In theory, a wormhole is a structure that connects two different points in spacetime. However, the size of the wormhole is too small to pass through and is unstable so that it collapses easily. This study aims to obtain Kruskal coordinate solutions for the Scwarzschild geometry in higher dimensions which can be useful for analyzing wormhole stability. This research was carried out by adding space from 3+1 dimensions to 4+1 dimensions to obtain Schwarzschild geometry, Eddington Finkelstein coordinates, and Kruskal coordinates by utilizing the radial motion of photons. The final result, the solution of the Schwarzschild spacetime geometry in Kruskal coordinates can be formed and illustrated in a Kruskal diagram. The diagram shows a black hole, a white hole, and the two universes connected by a wormhole.
