Comparing the implementation of fiscal term and condition for South East Asia countries is very interesting effort in order to study how oil and gas industry benefit to the host country and how they attract foreign investment through its different competitiveness aspects. In general, the oil and gas industry has been the main source of government income for this region particularly Indonesia and Malaysia for decades. * Hess Oil and Gas Sdn. Bhd ** Hess Indonesia this paper will hopefully give an idea of the contract terms of one country relatively to other countries for the given set of assumptions.
Lac is a non-timber forest product derived from the secretion of Laccifer lacca insects that are cultivated in kesambi tree (Schleicera oleosa Merr). Low lac production in Indonesia due to poor conditions of host plant indicated by poor growth symptoms, yellowing, and falling leaves. The aim of this research was to study the effect of molasses injection on the growth and vitality of kesambi tree. Molasses were injected into the plant using passive liquid injection methods. Pre-research activities were carried out by the tree trunk injection in 0.5, 1.5, and 2 meters above the ground using gentian violet to determine the best stem injection position, while the main research activity was performed by injection of the kesambi tree trunk using molasses in concentrations of 5, 10, 15% and water as control. The parameters measured at the pre-study was translocation length of gentian violet whereas at the main research were the volume uptake, the increase of branch diameter growth, total sugar content and chlorophyll content. Pre-research results showed that 1.5 meters above the ground is the best injection position. The main research results indicated that the highest volume uptake was water followed by others treatments. Molasses injection at concentration of 10% gives better effect on the increase of branch diameter growth (4.3 mm), obtained sugar content in 18.46%. The vitality of kesambi tree also increased by the molasses injection at concentration of 10%. It was shown by thein creased of chlorophyll a (1.117 mg/g), b (0.416), carotene (0.365), and Anthocyanin (0.094 mg/100g).
Kupu-kupu merupakan fauna khas di Taman Nasional Bantimurung Bulusaraung namun jumlahnya semakin lama semakin menurun. Upaya menjaga keberlangsungan ekosistem hutan terutama spesies kupukupu adalah dengan melaksanakan penanaman tumbuhan pakan larva (host plant) kupu-kupu. Salah satunya jenisnya adalah lada-lada (Micromelum minutum). Hal yang terpenting pada penanaman tanaman pakan adalah ketersediaan bibit. Tujuan penelitian ini adalah mengetahui media tabur, sapih dan naungan yang sesuai dengan lada-lada untuk produksi bibit yang optimal. Kegiatan ini dilakukan di persemaian dengan pengamatan pada perlakuan media tabur, media sapih dan naungan menggunakan Rancangan Acak Kelompok dengan 3 kali ulangan. Hasil penelitian menunjukkan bahwa Micromellum minutum dapat berkecambah dengan baik pada media pasir, tanah dan arang sekam padi maupun serbuk gergaji sedangkan media sapih dan naungan terbaik adalah campuran tanah, pupuk kandang dan sekam padi komposisi 1:1:1 dengan intensitas naungan 50%.

ABSTRACT
Butterfly population in Bantimurung Bulusaraung National Park is significantly decreasing. One way to keep the sustainability of this endemic and distinctive species is to carry out planting of fodder plants. Lada-lada (Micromelum minutum) is one species of fodder plants. The most important thing in planting fodder
ABSTRAKTersedianya tanaman murbei yang baik merupakan salah satu faktor penentu kontinuitas pemeliharaan ulat sutera. Penelitian bertujuan untuk mengetahui kecocokan hibrid jenis Morus khunpai dan jenis M.indica (hibrid KI) sebagai pakan ulat sutera yang dapat dilihat pada kualitas kokon dan serat sutera yang dihasilkan. Hibrid KI tersebut merupakan hasil persilangan terkendali dari induk betina M.khunpai dan induk jantan M.indica S-54. Penelitian menggunakan Rancangan Acak Lengkap. Variabel yang diamati adalah persentase larva mengokon, persentase kokon normal, bobot kokon, bobot kulit kokon, ratio kulit kokon dan panjang serat. Hasil penelitian menunjukkan bahwa kualitas kokon dan serat ulat sutera yang diberi pakan tanaman murbei hibrid jenis M.khunpai dan M.indica (hibrid KI) cenderung menunjukkan nilai lebih rendah dibanding murbei induk (M.khunpai, M.indica) dan kontrol (M.nigra) Kondisi ini menunjukkan bahwa kecocokan hibrid jenis M.khunpai dan M.indica (hibrid KI) sebagai pakan ulat sutera cenderung belum terlihat.
