"] Penelitian ini dimaksudkan untuk mengetahui bagaimana persamaan dan perbedaan karakteristik internal industri konveksi pada tiap tingkat produksi yang dihasilkan serta interaksi spasialnya terhadap asal bahan baku dan pemasaran. Analisis yang digunakan dalam penelitian ini yaitu dengan menggunakan analisis spasial deskriptif. Hasil penelitian menunjukan bahwa pada karakteristik internal industri kecil dan semi menengah umumnya memiliki tingkat produksi rendah dan sedang, sedangkan pada karakteristik internal industri menengah memiliki tingkat produksi yang tinggi. Interaksi spasial pada industri konveksi tingkat produksi tinggi memiliki skala regional dalam perolehan bahan baku dan skala nasional dalam pemasaran, sedangkan pada industri konveksi tingkat produksi sedang dan rendah tidak selalu memiliki perbedaan yang signifikan terhadap skala perolehan bahan baku dan pemasarannya. Industri konveksi tingkat produksi sedang umumnya memiliki skala regional dalam memperoleh bahan baku, sedangkan pada tingkat produksi rendah memiliki skala lokal dalam memperoleh bahan bakunya. Dilihat dari pemasarannya, industri konveksi tingkat produksi sedang dan rendah sudah dapat mencapai skala nasional. "

" "ABSTRACT
" This research is intended to find out the similarities and differences of the internal characteristics of the industrial convection at each level of production and to analyze the spatial interaction towards the origin of raw materials and marketing. The analysis used in this study by using descriptive spatial analysis. The research results showed that on the internal characteristics of small and semi medium industry generally have low and medium levels of production, while on the internal characteristics of medium industry have high level of production. Spatial interaction on the high level of production have regional scale in acquiring raw materials and national scale in its marketing, while on the medium and low levels of production don rsquo t always have a significant di fference against the scale in acquiring raw materials and marketing. Convection industry on the medium level of production generally have regional scale in acquiring raw materials, while on the low level of production have local scale in acquiring raw materials. Viewed from its marketing, convection industry on the medium and low levels of production can already achieve national scale.

A true revolution has rocked the space industry, as Silicon Valley and new startup companies around the world have shaken up the status quo. This has in turn triggered a hefty response among traditional aerospace companies, launching the sector into the new Space 2.0. This book explains how and why this remarkable change has happened, starting from the industrys origins during the Space Age and working its way to the present day. No other industry in the world has experienced the dramatic shift in technology and services as rapidly as the field of satellite services and rocket launch systems has. This book analyzes the dynamic shift over the past decade in how satellites are designed, manufactured, launched, and operated. It also turns an eye to the future, discussing the amazing feats and potential issues we can expect from this shifting arena by 2030. With its beginner-friendly writing style and plethora of illustrations, this book serves as a perfect introductory text to students and professionals alike wishing to learn more about the key trends in the field of space applications and launch systems.

Hamburan neutrino dengan materi bintang quark melalui interaksi lemah arus ne- tral telah dipelajari. Untuk menjelaskan keadaan materi quark, digunakan model bag MIT. Struktur bintang quark dapat dipelajari dengan memasukkan persamaan keadaan bintang quark kedalam persamaan TOV. Dalam tulisan ini kami mempela- jari penampang lintang differensial dan lintasan bebas rata-rata neutrino. Perhitun- gan dilakukan menggunakan dua metode; Pertama dengan memperhatikan hambu- ran N-body sebagai N kali hamburan dua partikel, Kedua dengan memperlakukan efek banyak benda dengan baik dalam hamburan N-body. Kedua pendekatan dipela- jari dan dibandingkan pada kasus temperatur nol. Untuk pendekatan pertama, interaksi didominasi oleh quark down, sedangkan untuk pendekatan kedua quark down dan quark strange memberikan kontribusi yang sama. Lintasan bebas rata- rata neutrino menurun dengan meningkatnya kerapatan, temperatur dan energi awal neutrino. Untuk kasus temperatur berhingga, terdapat beberapa faktor yang perlu diperhatikan, seperti; faktor retardasi, Pauli blocking dan detailed balancing. Pauli blocking dan detailed balancing secara signifikan mengurangi nilai lintasan bebas rata-rata neutrino. Sedangkan faktor retardasi menunjukkan sifat yang tidak biasa dari lintasan bebas rata-rata neutrino-quark strange. Selain itu, efek penangkapan neutrino secara signifikan menyebabkan fraksi elektron meningkat. Kontribusi elek- tron menurunkan lintasan bebas rata-rata neutrino. Lebih lanjut, lintasan bebas rata-rata neutrino dari pusat bintang quark hingga ke permukaan bintang semakin meningkat. ......The scattering of neutrino with quark star matter through neutral current weak interaction is studied. To describe the quark matter state, MIT bag model is used. The quark star structures can be studied by inserted the quark star equation of state into TOV equation. Here we study the neutrino differential cross section and mean free path. The calculation is performed by using two method; First by considering N-body scattering as N times two body scattering, Second by treating the many body effect properly in N-body scattering. Both approach are compared and studied for the case zero temperature, where we have found that for the first approach, interaction are dominated by the one from down quark, while the second approach the down and strange quarks provide similar contribution. Neutrino mean free path decreases with increasing density, temperature and initial energy neutrino. For finite temperatur case are several factors should be considered, i.e, retardation, Pauli blocking and detailed balancing factors. Pauli blocking and detailed balancing significantly reduce the value of the neutrino mean free path. While the retardation factor indicates unusual behavior of neutrino-strange quark mean free path. In addition, the effect of neutrino trapping is significantly increased the fraction of electrons. Contribution of electrons reduces the value neutrino matter mean free path. Therefore, the neutrino mean free path from the center of quark star to the stellar surface increases.
