Research on Hydroseeding in Indonesia is still limited. The application of this hydroseeding technique can be developed for landslide management. This study aims to analyze the percentage of growth (viability) and growth of Japanese grass (Zoysia japonica) planted on landslide soil media at various levels of slope. This research was carried out at the Central Laboratory and greenhouse of the Malang Agricultural Institute in March – July 2020. The soil media used was obtained from landslides in Ngantang, Malang Regency. A total of 5 kg of media was put in a plastic box. Then the box is placed on a shelf with a slope of 30o, 50o, and 70o. Japanese Grass Seeds obtained from the market are mixed with compost, soil conditioner, guar gum, water to form a Hydroseeding formula. The formula is then sprayed onto the growing media. The results showed that the application of hydroseeding with Japanese grass seed (Z. japonica) on media placed with a slope of 70o could potentially be used as a formula for the revegetation process of landslide-affected land. The hydroseeding treatment at this slope resulted in the highest seed viability and growth rate. Thus, Japanese grass (Zoysia japonica) has the potential to be used as a pioneer plant in land reclamation.

Tapping pine oleoresin using the borehole method produces clean oleoresin, so that the yield of turpentine increases. Turpentine produced by the oleoresin processing manufactory, raw materials come from several age classes of pine. This study aims to determine the yield and component of turpentine derived from tapping the oleoresin using the borehole method. The research was conducted in the Batu production forest area, East Java, Indonesia. A total of 150 pine trees for each age class IV, V and VI were sampled from each plot. Drill bit size using a 16 mm, and oleoresin drilling is done in the morning. Furthermore, the oleoresin that comes out is accommodated using a plastic bag for two days. Oleoresin pine is then distilled with temperatures of 160-180oC. The average yield of turpentine derived from pine age class IV was 19.52%, age class V was 19.93% and age class VI was 20.94%. Turpentine component was analyzed using Gas Chromatography MS to determine its content. The results of the analysis showed that the component of turpentine which had a large percentage in each age class consisted of, α-pinene, β-pinene, limonene, trans-2 carena, α-terpinolene, benzenemethanol and trans-pinocarveol. However, β-pinene was not found in the age of class VI and trans-2 carena was not found in the age of class IV

This study aims to analyze how well IT is used to support the business processes of SMEs in Bangunjiwo, and to identify ways to help SMEs improve IT support for business processes in SMEs in Bangunjiwo. This research is expected to have benefits that can increase managers/owners awareness to take advantage of the information technology support in business processes. By knowing the results of this study, the SMEs are expected to further improve the use of information technology in business processess as to achieve competitive advantage.The unit of analysis for this study is the SME organization, so every organization represented by one person (owner or manager). Population of the research is small and medium companies in Bangunjiwo, Kasihan, Bantul. The sample was selected using purposive sampling technique to determine which companies will be the respondent.The results show that IT support for each business process is lower than importance level that business processes run bySMEs in Bangunjiwo. IT support for SMEs in the business process can be enhancedby the disseminationof research results to the SMEs in Bangunjiwo, so they can understand the importance of IT support. Socialization is intended to motivate the use of IT facilities economically an deasily, so it can be done by SMEs.
