Judul: Faktor-Faktor yang Berhubungan dengan Efek Komunikasi dalam Pemasaran Lanting Ubi Kayu (Kasus Kecamatan Pituruh, Kabupaten Purworejo, Jawa Tengah)
Abstrak: The purpose of this study are; to analyze the relationship between internal factors and external factors to the marketing communications effect of cassava lanting. To understand the relationship of farmers in marketing communications effect cassava lanting to ward consumer purchases in terms of purchases number and purchasing motivation. The experiment was conducted in Pituruh District, Purworejo Regency, Central Java. There are two villages in the Pituruh District which are the central production of cassava lanting is Pituruh Village and Megulung Kidul Village. The choice of location is done intentionally because Pituruh District is the largest producer of cassava in Purworejo Regency. The selection of respondents was done by the census method that is selected 30 respondents who are still active in producing cassava lanting. The research method chosen is to use quantitative and qualitative data supported. Strategy obtain quantitative methods using survey techniques was descriptive and correlational research. Data collected in the research consisted of primary and secondary data. Data shows that internal factors are mostly connected with marketing communications effect of cassava lanting. Indicators of the communication effect is cognitive aspects, affective aspects, and conative aspects related to gender, productive time, and motivation to work. Education level and long work did not relate to all aspects of the communication effect. External factors largely unrelated to the marketing communications effect of cassava lanting. External factors that correlated with the communication effect in the aspects of labor only conative aspects and has a negative relationship. Effect of communications made by the seller cassava lanting in cognitive aspects, affective aspects, and conative aspects did not specify the purchases number and consumer purchasing motivations because the buyer's total purchases and motivation can be influenced by factors other than the seller.

Abstrak: Marketing communication is an attempt to convey the message to the public, especially to the consumer, about the existence of the product in the market. The purpose of this study is to analyze the factors that affect marketing communications. This study also aims to identify the characteristics of visitors and the implementation which done by the company. In this study the business units studied were Serambi Botani, Gandaria City Mall. Serambi Botani is one of business unit under the supervision of the Direktorat Bisnis dan Kewirausahaan Institut Pertanian Bogor (DITBK IPB) that sells processed agricultural products. The results of this study demonstrate the influence of the characteristics of marketing communications to the effectiveness of marketing communications, precisely on affective and conative aspects. Cognitive aspect is not affected by the characteristics of the visitors, the characteristics of marketing communications, nor the level of visitor’s exposure.

Judul: Solusi Geometri Schwarzschild untuk Dimensi 4+1 dengan Invarian Rotasi Isotropik
Abstrak: Metrik Schwarzschild merupakan solusi eksak pertama dari persamaan medan Einstein dengan mangasumsikan metrik statik dan simetris. Metrik Schwarzschild yang ditemukan oleh Karl Schwarzschild masih dalam dimensi 3+1, namun seiring dengan teori-teori terbaru yang menunjukkan bahwa alam semesta tidak hanya di dimensi 3+1. Maka melalui penambahan dimensi, tujuan penelitian ini memperoleh solusi pada geometri Schwarzschild untuk dimensi 4+1 dengan memodifikasi koordinat bola yang invarian rotasi isotropik dan melalui penurunan rumus seperti koordinat bola, simbol Christoffel, dan tensor Ricci. Selain mendapatkan solusi ini, metrik Schwarzschild dimensi 4+1 dapat digunakan sebagai metrik dasar untuk memperoleh solusi blackhole dan wormhole pada dimensi 4+1. Hasil akhirnya, dengan memanfaatkan modifikasi koordinat bola, metrik Schwarzschild dapat dibentuk sehingga diperoleh solusi geometri Schwarzschild untuk dimensi 4+1.
