Abstract

One of the wood sources in Indonesia is derived from private forests managed with agroforestry systems. The harvesting operation in these forests will produce harvesting residues. The study aimed to quantify the harvesting residue volume and to construct a prediction model for harvesting residue volume in a private forest managed with an agroforestry system. The study was conducted in a private forest managed with an agroforestry system in Probolinggo, East Java. The method employed for quantifying harvesting residue was a whole-tree method. The harvesting residue was classified into stumps, butt ends, top logs, and branches. Harvesting residues with dbh >= 4 cm were measured after harvesting. The best model was selected based on the Root Mean Squared Error and the adjusted coefficient of determination values.   The number of sample trees was 31 trees, which were chosen by farmers to be felled. The study found that the harvesting residues were 6% of the total harvested volume. The harvesting residue was predominantly the stumps. The best model for estimating harvesting residue volume in agroforestry private forests was V = 0.042VolTot1.248. The study concluded that harvesting operations in private forests managed with agroforestry systems produced a small number of harvesting residues. The harvested volume was the most significant indicator for estimating the harvesting residue volume.     Keywords: agroforestry, harvesting residue, private forests, predicting models

Abstract

Timber extraction in private forests in Indonesia is carried out using appropriate technology. Motorbike extraction is one of the means of timber extraction widely used in private forests in Indonesia. This research aimed to analyze the working time and productivity of timber extraction using motorbikes in private forests. The research was conducted in a private forest in Probolinggo, East Java. The terrain conditions at the study site were partly flat and partly rather steep. The study site can only be accessed through a footpath that is 2 m wide. Observations were made on three motorbikes. The number of trips for each motorbike was 11 trips. The skidding distance was 300 m. Data on timber extraction work time were obtained through video analysis. Production data on timber extraction were obtained through direct measurements in the field. The research showed that the work time spent to transport timber from private forests using motorbikes was 18.18 minutes per trip. The loaded travel spent the highest working time, followed by the empty travel, logs stacking, unloading, and traveling to logs. The efficiency of timber extraction using motorbikes in private forests was 82.11%. The productivity of timber extraction was 0.61 m3/hour or 0.002 m3/hour.m. Keywords: appropriate technology, motorbike, private forests, timber extraction, working time

Abstract

For the formulation of policy strategies on the use of environmentally friendly stimulant in the production of pine resin, the study of innovation stimulant is a necessity. This study aimed to identify the use of stimulants made from a strong acid (inorganic), ETRAT and wood vinegar on pine tapping. Research results revealed that the use of stimulants could increase resin flux and extend. Inorganic stimulant produced resin more than ETRAT and wood vinegar per collection in area with elevation above 500 ASL and below 500 ASL. The use of inorganic stimulant, however, caused the change of wood colour that will be dark brown to reddish even that going into as far as to the pith of wood. Meanwhile, the use of organic stimulant doesn't cause the change of colour in wood significantly. Therefore the use of stimulants on tapping pine needs to consider the negative effects of trees's health, workers and the environment.The economic aspect that should be persued to achieve the financial target, is not the main factor only but the ecological and sosial aspects to achieve a yield sustainability and tree producing are requared.

Abstract

Bamboo forests serve as valuable assets which assist in developing social forestry programs that benefit local communities. The research investigates how bamboo grows and its economic value through two different planting methods which include monoculture and mixed systems at a Indonesian village forest. Researchers used systematic sampling methods to collect data from 21 plots which included 14 monoculture plots 6 mixed-system plots and 1 shrub plot. The research team focused on gathering data about clump characteristics and culm density and regeneration proportion. The researchers used the Mann–Whitney U test to analyze system differences because the data did not follow normal distribution. The study results show that monoculture bamboo systems produce higher output levels and generate greater financial benefits than mixed systems. The monoculture stands achieved an annual output of 6,374 culms per hectare which results in an estimated economic value of IDR 50,992,000 per hectare every year. The mixed systems produced 5,242 culms per hectare each year whereas the system generated an output of 5,242 culms. The study found that monoculture systems produced more young bamboo regeneration which reached 30.8% compared to mixed systems which generated 27.0% of young bamboo regeneration showing that monoculture systems have better regenerative capabilities.

Abstract

Pengeluaran kayu menggunakan sepeda motor merupakan teknik pengangkutan kayu jarak pendek yang sedang berkembang dan banyak digunakan di kegiatan pemanenan hutan rakyat di Indonesia. Penelitian ini bertujuan untuk menganalisis biaya pengangkutan kayu jarak pendek menggunakan sepeda motor di hutan rakyat. Penelitian ini dilakukan di salah satu hutan rakyat yang ditanam dengan pola monokultur di Probolinggo, Jawa Timur. Data yang dikumpulkan meliputi waktu kerja, produktivitas dan biaya pengangkutan kayu. Hasil penelitian menunjukkan bahwa biaya pengangkutan kayu menggunakan sepeda motor di hutan rakyat sebesar Rp. 65.085/m3 untuk jarak sarad 300 m. Biaya variabel pengangkutan kayu menggunakan sepeda motor di hutan rakyat mencapai 94,6%, sedangkan sisanya (5,4%) merupakan biaya tetap. Komponen biaya tetap terbesar adalah depresiasi, sedangkan untuk biaya variabel adalah biaya tenaga kerja. Porsi biaya tenaga kerja pada pengangkutan kayu menggunakan sepeda motor adalah sebesar 58,77%, biaya bahan bakar dan pelumas 30,78% dan biaya alat sebesar 10,45%. Pengangkutan kayu menggunakan sepeda motor di hutan rakyat dapat menjadi lapangan kerja potensial bagi masyarakat di sekitar hutan rakyat.

Abstract

Situ Gede offers various ecotourism resources, such as research forests, Situ Gede Lake, natural landscapes, and diverse types of flora and fauna that attract tourists. To increase the number of visitors, these resources need to be developed effectively. As tourists visiting Situ Gede have different characteristics, motivations, and preferences, these differences must be studied to develop ecotourism in Situ Gede. The research aims to identify the motivation, preferences, and evaluations of visitors that can be used to develop ecotourism in Situ Gede. The study uses a 1-4 Likert scale, and data analysis involves descriptive methods, calculating standard deviation values, and Pearson Chi-Square analysis. The research findings indicate that the primary motivation for respondents to visit is physical. Three tourism activities are influenced by age, namely meeting friends, being with family and attending meetings, and culinary tourism. The activities around the lake that are most popular with visitors are taking selfies, enjoying the lake's beauty, and having a picnic in a natural setting. The most popular activities in the Research Forest are relaxing and enjoying the forest atmosphere, observing the variety of plants there, and taking photos with a forest background.
