Abstract

The utilization of private forests in Indonesia that is not managed properly based on the principle of sustainable yield will result in the depletion of private forests in the not too distant future. Therefore the sustainability of private forest is a necessity that cannot be delayed anymore. The general objective of this research is to find out whether the yield regulation method (Brandis Method) can be applied in private forests. The specific objectives of this study are: (a) to analyze the characteristics of pine private forests and their suitability for the Brandis Method practice, and (b) to know the sustainability of pine forest products in Tana Toraja using the Brandis Method and its institutions. The data collected in this study consist of primary and secondary data. The analytical method used was descriptive analysis and yield regulation method was analyzed based on Brandis Method. The result of this study shows that the yield regulation of the private pine forests in Tana Toraja can be done based on the number of trees using the Brandis Method. The regulation of private forest products based on the number of trees can be carried out if there is support from private forest institutions.

Abstract

Eucalyptus urophylla is one of the typical plants of the Province of East Nusa Tenggara,  Indonesia whose distribution includes the islands of Timor, Alor, Wetor, Flores, Adonara, Lomblen, and Pantar. The best land for the growth of E. urophylla is an area with rainfall above 1000 mm every year. E. urophylla dominate the island of Timor hence the potential to absorb carbon and store it in biomass as part of climate change mitigation. This study aims to determine the allometric equation model to predict the potential of E. urophylla stem biomass. Calculation of the amount of stem biomass based on allometric equations is an analytical method used in this study. The sample trees used in equation modeling is 100 trees as a result of the inventory. The equations that can be used to estimate the biomass potential of the stem of  E. urophylla in Timor Island were ln  = -2.12 + 2.472 ln ( ) and (R2= 0.98); ln  = -3.617 + 1.046 ln  and (R2= 0.99); and ln  = -3.510 + 2.157 ln ( ) + 0.983 ln  and (R2= 0.99). The stem biomass potential with the model I amounting to 276.877 tons ha-1, model II of 279.671 tons ha-1, and model III of 280.209 tons ha-1.

Abstract

Pinus merkusii Jungh et de Vriese is a plant with high market and economic values due to providing a variety of products, including wood. Good management is needed to preserve pine forest products. The first step toward effective forest management is developing a management plan based on estimated stock data. The volume table used has a significant impact on the accuracy of the stock potential estimate. This study aims to determine the best equation model for compiling a local volume table for P. merkusii Jungh et de Vriese in Tana Toraja Regency. The research was conducted at the community pine forest in Gandang Batu Sillanan and Mengkendek districts, Toraja Regency. The number of sample measured was 100 trees. An analytical method was used to calculate the amount of tree volume on allometric equations. The equation for the stem volume was made using the allometric equation. The research results showed that diameters' mean, standard deviation, and sampling error values were 28.34 cm, 7.39 cm, and 1.45, respectively, heights were 23.77 m, 7.37 m, and 1.44; volume was 1.44 m3, 0.96 m3, and 0.19. The regression equation modelling showed that the best equation model for estimating volume P. merkusii Jungh et de Vriese based on height and diameter was ????=????????2????.

Abstract

ABSTRACTFood security remains a serious issue for Indonesia, as the availability and distribution of food is unequal in all regions of the country. There is surplus production of cereals (rice and maize) in most provinces in Indonesia, but there are still provinces with production deficits. The planting patterns of private forests established in Indonesia are very diverse and are intended to become a source of food for the community. The objectives of this study are 1) to identify different private forests that have been developed for food crops, and 2) to determine the availability of food for farming households from private forests. Primary and secondary data are used for this study. Primary data collection is done through structured interviews with questionnaires. The results show that the form of private forest for food supply is developed by using agroforestry patterns with areas ranging from < 1 hectare to > 1 hectare with different combinations of food crops. There are seven types of crops grown in private forest that have high value and are needed by farmhouses.Keywords : private forest, food security, agroforestry, food availability ABSTRAKKetahanan pangan masih menjadi masalah yang serius untuk Indonesia, karena ketersediaan dan distribusi pangan yang belum merata di seluruh wilayah Indonesia. Surplus produksi serealia (padi dan jagung) terjadi di sebagian besar provinsi di Indonesia, namun masih terdapat provinsi yang mengalami defisit produksi. Pola tanam hutan rakyat yang dikembangkan di Indonesia sangat beragam di setiap daerah, dan diharapkan dapat menjadi sumber pangan bagi masyarakat. Tujuan penelitian ini adalah 1) mengidentifikasi berbagai bentuk hutan rakyat yang telah dikembangkan untuk budidaya tanaman pangan, dan 2) mengidentifikasi ketersediaan pangan untuk rumah tangga petani dari hutan rakyat. Penelitian ini menggunakan data primer dan sekunder. Pengumpulan data primer dilakukan melalui wawancara terstruktur menggunakan kuisioner. Hasil penelitian menunjukkan bahwa bentuk hutan rakyat untuk penyediaan pangan dikembangkan dengan pola agroforestry dengan luasan lahan bervariasi antara < 1 ha dan > 1 ha. dengan kombinasi tanaman pangan yang berbeda. Terdapat tujuh jenis tanaman yang dihasilkan dari hutanrakyat dan mempunyai nilai tinggi serta dibutuhkan oleh rumahtangga petani.Kata kunci: hutan rakyat, ketahanan pangan, agroforestry, ketersediaan pangan

Abstract

The condition of culinary tourism in Bogor is dominated by modern cuisine, which has led to the exclusion of traditional cuisine. This research aims to determine the factors influencing tourist or consumer satisfaction in choosing traditional culinary delights in Bogor City. The method used in this study is quantitative. The analysis used in this research to determine the level of feasibility of the questionnaire used was the validity and reliability test to test the questionnaire for determining the attributes of tourist or consumer satisfaction. The subsequent analysis used in this research is a regression analysis to determine the factors influencing consumer satisfaction in choosing traditional culinary delights in Bogor City. The research results show that culinary products can make tourists or consumers satisfied. Bogor City's traditional culinary products consist of a variety of products with varying levels of taste, quality, presentation, and packaging. The price, service, or motivation don't affect tourist satisfaction when choosing culinary.
