Judul: Pemanasan sekunder plasma menggunakan gelombang mikro untuk reaksi fusi terkontrol
Abstrak: elah diteliti pengaruh pemanasan sekunder pada plasma dengan menggunakan gelombang mikro, yang dijalarkan tegak lurus dengan medan magnetik toroidal dalam tokamak. Didapat nilai numerik daya P =ψψm ≈ 1,305×10-15 W/m3 yang diserap oleh elektron per volume terhadap pemanasan sekunder menggunakan gelombang mikro yang penjalarannya tegak lurus dengan arah medan magnetik toroidal. Nilai yang kecil menunjukkan nilai rerata terhadap banyaknya partikel dalam plasma. Adapun diperolehnya nilai radius rm ≈ 1m yang mendapat nilai serapan terbesar menunjukkan bahwa pada lokasi tersebut terdapat sumbu magnetik, yang sebelumnya diasumsikan berada di pusat lingkaran penampang poloidal tokamak.

Judul: Analysis of Increasing Plasma Temperature for D-T  Fusion Reactions in Tokamaks with Ohmic Heating
Abstrak: Reaksi fusi terkendali atau termonuklir terkendali merupakan reaksi penggabungan dua inti atom ringan menjadi inti atom yang lebih berat dengan melepaskan energi. Reaktor fusi hingga saat ini masih dalam pengembangan demi terwujudnya pembangkit listrik tenaga nuklir berbasis reaksi fusi. Biaya kontruksi menjadi salah satu faktor penghambat perkembangan reaktor fusi dunia. Penelitian ini bertujuan untuk menghitung suhu yang dapat dicapai plasma yang dipanaskan secara ohmik dalam reaktor fusi bernama Tokamak dengan ukuran radius yang divariasikan. Ukuran radius mayor yang digunakan dalam perhitungan dengan rentang 2 m sampai 4 m serta radius minor 1 m sampai 3 m. Nilai tersebut ditetapkan lebih kecil dari Tokamak yang pernah ada demi terwujudnya penekanan pada biaya konstruksi. Ukuran radius mayor memiliki peranan dalam jumlah tumbukan partikel terjadi sehingga berbanding lurus dengan suhu yang dicapai plasma. Ukuran radius minor memiliki peranan dalam proses konversi panas melalui dinding reaktor sehingga hubungannya berbanding terbalik dengan suhu yang dicapai plasma., Fusion control or controlled thermonuclear is a reaction that combines two light atomic nuclei into a heavier atomic nucleus by releasing energy. Fusion reactors are currently still being developed to realize nuclear power plants based on fusion reactions. Construction costs are one of the factors inhibiting the development of world fusion reactors. This research aims to calculate the temperature that can be reached by ohmically heated plasma in a fusion reactor called Tokamak with varying radius sizes. The size of the major radius used in the calculation ranges from 2 m to 4 m and the minor radius from 1 m to 3 m. This value is set to be smaller than existing Tokamaks in order to reduce construction costs. The size of the major radius plays a role in the number of particle collisions that occur so that it is directly proportional to the temperature reached by the plasma. The size of the minor radius plays a role in the heat conversion process through the reactor walls so that the relationship is inversely proportional to the temperature reached by the plasma.

Judul: The Dynamic of Population Succession Insect as an Indicator Forensic Activities
Abstrak: The decomposition stage of carrion will attract various species of insects to come. Some species of insect will attract the carrion in the early stage of decomposition, but some of them in the late stage of death. The purpose of this research were to observe and analyze the distinctive features of insect succession on carrion. Two carrions were placed in indoor and outdoor. Insect collection and observation was done three times a day i.e, morning, afternoon and evening. Adult flying insects were collected by sweeping net, whereareas the immature insect manualy. The result showed that decomposition of the carrion indoor were faster than the corrion outdoor. Total time an early stage until skeletonization stage on carrion outdoors was 10 days and indoors for eight days. In outdoor there were found orders of Diptera (i.e Muscidae, Calliphoridae, Sarcophagidae, Tachinidae), Coleoptera (Chrysomelidae, Staphylinidae, Scarabeidae, Silphidae), Hymenoptera (Formicidae), Hemiptera, Blataria and Orthoptera (Grillidae). However, in indoors there were found the order of Diptera (Muscidae, Calliphoridae, Sarcophagidae, Tachinidae), Coleoptera (Chrysomelidae, Staphylinidae, Scarabeidae, Silphidae), Hymenoptera (Formicidae), Hemiptera, Lepidoptera, and Aranea. Immature insects that are found outdoors and indoors consist of three family of Diptera i.e Calliphoridae, Muscidae, and Sarcophagidae. The presence of Diptera larvae in carcasses have been found from the early stage of the death until post decay stage. The soil insects that come to the carrion outdoors consist of Protura, Collembola, Thysanura and oribatid mites. The presence of soil insects from early stage until skeletonization stage.
