Judul: Kelayakan usaha kapulaga (Amomum cardamomum) di desa sedayu kecamatan loano kabupaten purworejo, wilayah kph kedu selatan perum perhutani unit 1 Jawa Tengah
Abstrak: One of the medicinal plants needed by community is cardamom (Ammomum cardamomum) but relatively little in supply. It is one of the herb plants which has high economic value and good prospects. Its potential development in Indonesia is quite high, but the increasing of production do not fulfill the market demands on domestic and international yet. Regarding to this case Sedayu farmers try to optimize the using of Perhutani land through planting cardamom as sidelines plant on pine stands. The election of cardamom as sidelines plant was not without reason. Basically multicultural planting can be more profitable if those plants could maximally exploit environmental resources along growth period. The decision for conservation of monocultural pine into multicultural with cardamom are needed to be reviewed in financial aspect avoid the risk in order to of loss and analysed see the marketing prospects in Sedayu. Primary data were collected by using Purposive Sampling method. This means that each element did not get the same chance to be selected. The taken samples foe particular purpose were 40 farmers, through interviewing and observing. While method to determine the market prospects is survey, which used Snowball Sampling in respondents taking. Based on beginning of this identification would be found in the next sample units, which determining the initial sample and the next samples based on the information obtained. The results of on financial aspect analysis including NPV, Net B/C, IRR, and Payback Period, the cardamom cultivation in Sedayu were worthed to be conducted. This is indicated by the value of NPV > 0 amount of IDR 31,885,009; Net B / C> 1 is 1.3; and IRR of 22.29%, where the value is higher than interest rate (discount factor) of 13% and the payback period obtained in cardamom cultivation is 4.23 (4 years 3 months). Cardamom cultivation has good market prospects. This is caused by the demand for cardamom still relatively high. The number of requests from traders still not be fulfilled by farmers so that the value of excess demand is high.

Judul: The Development Of Indonesia Cardamom Export And The Factors That Affect
Abstrak: Agricultural sub-sector in Indonesia medicinal crops are one of the advantages that have great potential to develop and affect the national economy. Cardamom is a medicinal plant, and a food stitch. Indonesia already exports cardamom to international markets and has the potential to be the world's largest spice exporter. Indonesia with good cardamom quality and large quantity, cardamom can be one of the great export commodities and can be utilized to increase the country's foreign exchange and increase farmers' income in Indonesia. The purpose of this study is to analyze the condition of cardamom development in the international market, analyze the factors affecting cardamom exports in Indonesia, and analyze the development of Indonesia's cardamom exports to international markets. This research will use multiple linear regression analysis with ordinary least square (OLS). Secondary and variable data used in this study are: (1) cardamom production volume, (2) cardamom export price, (3) rupiah real exchange rate against dolar, (4) world oil prices, (5) Indonesia GDP annual growth. All variables data used in the period from 2000 to 2019. The result of this research shows the factor of cardamoms export affected significantly by production volume and world oil prices., Agricultural sub-sector in Indonesia medicinal crops are one of the advantages that have great potential to develop and affect the national economy.

Judul: Transisi Fasa Materi Hadronik ke Materi Kuark pada Inti Bintang Neutron.
Abstrak: Bintang neutron terdiri dari beberapa lapisan yang disusun oleh materi nuklir yang berbeda dengan kerapatan yang semakin tinggi ketika mendekati pusat bintang. Inti luar bintang neutron disusun oleh materi hadronik (nukleon, lepton, dan hyperon), sedangkan inti dalam bintang neutron disusun oleh kuark-kuark bebas (up, down, strange) yang saling berinteraksi. Tujuan penelitian ini adalah mempelajari bagaimana transisi dari inti luar ke inti dalam bintang neutron dengan menggunakan pendekatan RMF (Relativistic Mean Field) untuk materi hadronik dan CIDDM (Confined Isospin Density Dependent Mass) untuk materi kuark. Tekanan transisi diperoleh ketika potensial kimia barion materi hadronik dan materi kuark bernilai sama. Nilai tekanan transisi dengan parameter SU6-TM1 sekitar 87 MeV/fm3 dan diperoleh massa maksimum bintang neutron yaitu 1.92M dengan jari-jari sekitar 8.62 km. Nilai tekanan transisi dengan parameter SU6-G2 sekitar 53 MeV/fm3 dan massa maksimum bintang neutron yaitu 1.88M dengan jari-jari sekitar 8.16 km. Jenis transisi fasa adalah orde satu ditandai dengan diskontinuitas dalam kerapatan energi (adanya mixed phase). Parameter-parameter pada model nuklir yang digunakan menyebabkan perbedaan kekakuan persamaan keadaan (EOS) dari materi hadronik dan materi kuark sehingga nilai tekanan transisi dari fasa hadronik ke fasa kuark juga berbeda.
