Casuarina junghuhniana or mountain ru, she oak or cemara is a species from Indonesia which grows in the highland area at an altitude between 2000 - 3000 m above sea level (asl). One of the highland area in Eastern Java (Jawa Timur) of Indonesia is Bromo Tengger Semeru National Park (TNBTS). The study site was on the Tengger Sea of Sands, Eastern Java, Indonesia where it is affected by volcanic activity. This tree, from some references, has not been well studied yet although it has been reported as a tree native to Indonesia. The lack of the study poses problems when there is a program related to planting the tree on a certain location in TNBTS for rehabilitation purposes. This study attempted to construct a Structural Equation Model that mapped some factors observed in the study site related to C. junghuhniana population. Explored factors for their relationship with each other included the number of male and female individuals, growth-related indicators, and environmental factors consisting of altitude and the tree population. Formative factors which consist of parameters related to growth, environmental factors and factor associated with the diffusion of new individuals, may contribute to population growth while population growth was the opposite. The individual growth might not significantly contribute to the population of C. junghuhniana; instead, the population growth was affected by the tree individuals. Generative reproduction contributed the least to the dispersal as it may rely more on vegetative reproduction by adventitious shoots from roots.

The aim of the research was to obtain the method of porang’s tuber dormancy breaking. The source of porang’s tuber were obtained from Rejosari Village, Bantur Subdistrict, Malang Regency. The diameter and weight of porang’s tuber were 5-7 cm and 100-150 g respectively. The research design was Completely Randomized Design. Porang’s tubers were storaged in the photoperiod cabinet during one month. The levels of photoperiod were 0, 8, 12, 16, 20, and 24 hours/day. The light intensity of TL lamp was 400 lux. As a control it was used porang’s tuber that it was placed in the dark cabinet without light. Repetition was four times. The success of dormancy breaking was observed through the tuber capasity to grow that it was identified by bud emerged. Data were analyzed by ANOVA that it was continued by Duncan test (α = 0.05). The results showed that photoperiod 8, 12, 16, 20, and 24 hours/day during one month could stimulate porang’s tuber dormancy breaking. Photoperiod 16 hours/day emerged the height of buds 4.97 ± 1.20 mm and the diameter of buds 7.28 ± 1.22 mm at photoperiod 24 hours/day. The growth of porang’s tuber which is treated by photoperiod during one month were significantly different with control. Photoperiod 16 hours/day emerged the height of plants and the diameter of petiole were 106.38 ± 15.11 cm and 2.90 ± 0.29 mm respectively, while the width of canopy was 72.50 ± 22.17 cm at photoperiod 24 hours/day. Besides, the diameter and weight of harvest tuber were 7.93 ± 2.20 cm and 383.20 ± 23.58 g. The weight of harvest tuber increased 255% from the early weight of tuber. Photoperiod treatment promote breaking of porang’s tuber dormancy.

Along with the development of culture, both traditional and biotechnology, the use of pandan, as can be found either in the community, traditional markets, experiencing a shift which was replaced by other materials, such as by plastic straps, caps from fabric. Ethnobotany study done by collecting a "ethnodirect sampling" technique with direct or semi-structural interviews. The method is carried out at pandan anatomy including: methods for extracting fiber, making transverse and longitudinal leaf preparations, measurements of leaf length and fiber strength and making preparations transversal and longitudinal of supporting root. The long term goal of this study is to obtain a data base of pandan (Pandanaceae) that can later be used to perform resource management in pandan (Pandanaceae) to its preservation in East Java, thus supporting ecological functions and the resulting types are also cultivating other Pandan also potentially. The short term goal is to get the kind of pandan (Pandanaceae) is useful to be developed as a craft that can later be used to improve the economy of East Java community through anatomical structures. The three types of pandan namely P. tectorus, P. labyrinthicus and P. furcatus has the potential to be developed as a base for the manufacture of rope and handicrafts. The potential of plant-based crafts from fiber can still be developed on the craft of Pandanus.

Indonesia is the third richest country for pigmented rice source such as Wojalaka black rice of East Nusa Tenggara (NTT), Manggarai of NTT, Toraja of South Sulawesi, Cempo Ireng of Central Java and red rice of Aek Sibundong (leading variety) and Baubau of Southeast Sulawesi. However, the morphological character of pigmented rice in Indonesia is less reported. The objective of research was to compare the morphological variation of root, stem, leaf, panicle, floret and the colour of milk mature grain and mature grain by observing the vegetative and generative parts of six local rice varieties. Research had been conducted from February 2012 to February 2014 in Sengguruh Village, Kepanjen District, Malang Regency. This study type was quasi-experiment with eleven replications. Group Random Design was used. The observation was given upon vegetative, reproductive and maturity phases as groups. Independent variables in this study were six rice varieties, while the dependent variable was morphological variation (root, stem, leaf, panicle, floret, milk mature grain and mature grain). The analysis of multivariate data in cluster and bip lot was carried out with PAST. The result of the study indicated that there was morphological difference on stem, leaf, panicle, floret, milk mature grain and mature grain. The colour of the stem in Aek Sibundong variety was purple, while that of other varieties was green. Toraja and Manggarai varieties had the highest height with 163-168 cm, followed by Cempo Ireng with 139 cm, Wojalaka and Baubau with 110-112 cm. Aek Sibundong Variety had the lowest height with 99 cm. Aek Sibundong and Wojalaka varieties had 6-7 internodes which were the greatest number of internode, while other varieties only had 4-5 internodes. Some varieties, such as Aek Sibundong, Wojalaka and Baubau had short and small leaf. The leaflet angle of Aek Sibundong and Baubau were 14o and it might be said as upright, while that of Wojalaka was 43o or moderate. Cempo Ireng, Manggarai and Toraja had its 63-88o of the leaflet angle or it was saidas flat. Cempo Ireng and Wojalaka were included into Rice Indica Group while Toraja, Manggarai, Cempo Ireng and Baubau belonged to Rice Javanica Group. There were two morphological groups. Group 1 included Toraja, Manggarai and Cempo Ireng, while Group 2 consisted of Aek Sibundong, Baubau and Wojalaka.
