Abstract

Terrain analysis and elevation profiling are widely utilized in geographical studies where spatial information system is one of the foremost tools in assessing characteristic patterns of hiking trails and plain areas suitable for a campsite. The main objective of this study is to classify the landforms of Batu Gangan Forest Reserve by conducting a morphometric analysis of the Digital Elevation Model (DEM) with 10m resolution. The classification process is based on calculating the Topographic Position Index (TPI). Using TPI, the landscape was classified into slope position and landform categories. The delivered TPI landform classes are spatially correlated with the elevation, slope, LS factor, and topographic wetness of the mountain. Site observation was carried out to identify water sources, viewpoints, and their significance as suitable campsites and potential trail. An alternative trail was proposed to reduce the visitor impacts towards the main trails. The result suggested that the plains landform only covered 3.26% or 2.03km2 of the study area, where two potential campsites were identified. The method presented and research findings derived from the study are beneficial to support sustainable recreation resource planning, especially in a complex mountainous area. The study's findings and data will lead to proper forest use for recreational reasons consistent with conservation efforts.

Abstract

Karang Mumus watershed is an important area as a port and gateway to the inland of East Kalimantan, causing the trade sector and water transportation services in this city to be very developed. Traders and immigrants from various regions who came in, stopped by, performed business, and stayed have caused the riverbanks to develop into economic and trade centers. One of the issues in the Karang Mumus sub-watershed is the conversion of forest area to agricultural land. With the improper use of agrotechnology and soil conservation, agricultural operations result in erosion and reduced land yield. This study aims to evaluate the Karang Mumus sub-potential watersheds to support land capability by using the overlay method (geoprocessing) of a geographic information system (GIS) based on criteria for classifying land capabilities and a data analysis approach. The findings revealed that the Karang Mumus sub-land watersheds primarily are categorized as land capacity class III, with a moderate erosion limiting factor that covers 15,864 ha (50.45%). The remaining areas are categorized into land capability classes IV and VI, with class IV having a severe slope limiting factor and class VI having a severe slope limiting factor with a fairly strong soil sensitivity to erosion, covering 8,751.14 ha (27.83%) and 6,829.85 ha (21.72%), respectively. Class III land is recommended for agricultural cultivation, application of appropriate agro-technology, and soil and water conservation. This study recommends that class IV and VI lands area are used for community forests or plantation forests managed by government agencies involved in the forest area stabilization center (BPKH) Region IV Samarinda.

Abstract

This study aimed to evaluate the Tourism Management CHSE Protocol during the Covid 19 Pandemic in the Situ Gunung Gede Pangrango National Park Area. The framework of the approach used in this research was phenomenology, which was then enriched with the data collection techniques of study documentation, observation, and close-ended questionnaire. The analytical method utilized was the One Score One Indicator Scoring System, an analysis model that was used through developing elaboration of questionnaires in collecting data and evaluating various variables that researchers had determined. Then, two critical issues were examined in the polarization analysis to understand the differentiation between actors, namely polarization of direction and rating scale, and then tested statistically using Kruskal Wallis test to know the polarization significance. Overall, based on the assessment of 189 CHSE indicators, the data shows that the implementation of CHSE in Situ Gunung GGPNP results in a reasonable conclusion or score of 6. When viewed based on stakeholder polarization where the data shows there is no polarization of direction between stakeholders on CHSE management at Situ Gunung. Things are different when viewed in terms of average values, where the study results show the polarization of each actor's attitude scale on the CHSE implementation assessment. The aggressive strategy is carried out by optimizing three crucial aspects: 1) Strengthening CHSE Management Policies and Implementation; 2) Optimizing Ecotourism Carrying Capacity.

Abstract

Nowadays the study of phenology has taken an important contribution to climate change research. Therefore this study observed local fruit trees species collected in the Purwodadi Botanical Gardens (PBG); they were Flacourtia rukam (Zoll & Moritzi), Limonia acidissima L., and Manilkara kauki (L) Dubard. We used fruit phenology data from 2014 to 2018 as secondary data to describe the changes. We also observed the weekly phenology of flowering and fruiting for three years from 2019 to 2022. At the same time, mesoclimates components included precipitation, maximum and minimum temperature were daily recorded by the PBG weather station measurement. Data pairs were then analyzed by using a structural modeling of WarpPLS to determine the relationship among mesoclimates and phenology variables. Research showed that phenology of flowering and fruiting of F. rukam, L. acidisissima, and M. kauki was significantly shifted from 2014 to 2022, along with changes in rainfall patterns, maximum and minimum temperatures in the PBG. Based on the Friedman test, it was shown that the maximum and minimum temperatures significantly changed (p<0.05). Five months of mesoclimates were significant predictors and affected before the measurement of phenological flowering and fruiting of three species. High precipitation significantly reduced maximum temperature, and increased minimum temperature. The high precipitation reduced the probability of flowering and fruiting initiation, except for those of L. acidissima. Increasing maximum temperature reduced flower and fruit set of F. rukam and L. acidisissima, while it reduced flowering of L. acidissima. Furthermore, minimum temperature induced flowering, except in L. acidissima.

Abstract

The incident of fallen trees or broken branches is dangerous for tourists visiting Bali Botanical Garden. Tree health monitoring in locations with high human activity and near valuable properties is mandatory to minimize the potency of tree failure. Since the stand stability is influenced by biological and physical factors, multiple variables consisting of species characteristics (stem form), tree dimensions (height, diameter, and slenderness coefficient), and tree health were used as parameters of tree health. The aim of this study is to examine the health condition of trees located in XIV.G Bali Botanical Garden and to identify the most significant morphological character related to the result of tomograph measurement. A purposive sampling technique was adopted for locations which highly visited. A total of 80 trees were examined as samples to measure tree health. The evaluation used visual observation and tomograph technology. The result showed the most tree defect found were branches covered with epiphyte and moss. However, tomograph examination found only one tree classified at high risk (Bischofia javanica) and seven trees classified at medium risk (Syzygium polyanthum, Syzygium racemosum, Bischofia javanica, Pittosporum mollucanum, Pittosporum sp. and Dacrycarpus imbricatus (2 trees)). This study suggests the use of tree architecture model as the most significant morphological character on tree samples with medium decay.

Abstract

Sago (Metroxylon) is one of the local food species with development potential. Lingga Regency is one of the potential locations for sago development. However, no research on the morphological characteristics and production of sago in Lingga Regency has been conducted. The purpose of this research is to determine the morphological characteristics and production of sago in Lingga Regency. This study's sago plants came from six sago-producing villages. Before and after the sago trees were harvested, morphological characteristics and production were observed, with random sampling at each research site. Field observations on the potential of sago stands were conducted at the study site using the transect method with a single plot. Based on morphological characters there are two types of sago in Lingga: spiny and thornless sago. The morphological characteristics and sago production vary greatly between research sites. Sago stands have a production potential ranging from 3.37 to 14.55 tons ha-1. Because they have a starch content of more than 200 kg stem-1, the majority of sago accessions in Lingga are superior accessions with the potential to be further developed. Superior sago comes from the villages of Musai, Pekaka, Keton, and Teluk.

Abstract

Dayak Lun Dayeh is one of local community who lives in East Kalimantan, where they’ve mostly practiced hunting traditionally, has particular ways to find hunting spot and use hunting techniques sustainably. The research about this community was conducted in river bank of Mentarang in order to determine the various kinds of game animal, frequently used hunting ground, and hunting ways of Dayak Lun Dayeh community at two different times, on May-July 2016 and June-August 2021. Research data were collected through open ended interviews (assisted by key informants), field observations and animal photos. Data were presented descriptively by ethnobiology approach. The results showed that this community practices subsistence hunting of wild animals, which comprised of mammals (69-73%), reptiles (14-15%), aves (8%) and amphibians (0-4%). The meat obtained from hunting(s) were consumed as protein source, served as medium in traditional ceremonies or religious rituals based on ancestral teachings. Wild animals such as Cervus unicolor, Sus barbatus, Muntiacus atherodes could be found easily in abpa’ nuvan (salt lick) rather than primary forest, swidden (latii), swidden fallow (included amug, jekau and ripa), farm, river, or secondary forest such as the logging roads of former timber company. Several hunting techniques were applied such as using hunting dogs for tracking the game animals (gelibut), sieging or waiting (gabang) at specific location (abpa’ nuvan), and setting traps (ton).

Abstract

Community and private partnership (CPP) in tree planting initiative is potential to accelerate rehabilitation of degraded lands. Yet, empirical studies to analyse such programs are limited. Here, we analysed a CPP tree planting program in East Java, Indonesia by focusing on ecological aspects, i.e. vegetation cover changes, floristic diversity, above-ground carbon storage, and soil and microclimate conditions. Results showed that there was a striking increase in vegetation cover, yielding a total carbon sequestration of 3,853 tons, or equivalent to the reduction of 14,140 tons of CO2 emissions. On the other hand, co-benefits in term of floristic diversity at a landscape scale was low, and soil and micro-climate conditions were still marginal. This study provided empirical evidence that collaboration between communities and private entities in tree planting program can be effective in rehabilitation of degraded lands. Improvement in land management systems applied in tree planting through the implementation of mixed gardens or complex agroforestry is suggested if aiming for co-benefits in floristic diversity and soil properties. Our study recommends a broader adoption of a similar scheme in rehabilitation of degraded lands across Indonesia.

Abstract

Illegal logging in Papua's forest areas has been a cause of unresolved degradation or deforestation and has developed into a complex problem. This study intends to elaborate on the complex dynamics of illegal logging in Papua, Indonesia, using Niklas Luhmann's Social System theory. The findings of this study are expected to provide a better understanding of the complexities of illegal logging and to encourage stakeholders to respond with more appropriate decisions and policies in accordance with their respective roles and authorities. The results of the research show that illegal logging in Papua is a social system that is formed from a simplification of the meaning of forests by actors who are purely economic-oriented. In facing the pressure from efforts to eradicate this system, the system has been reproducing in an autopoietic manner through differentiation to penetrate all other social systems pointed toward handling illegal logging and sustainable forest management, especially the law enforcement system and the customary forest community system. The ability of autopoietic to reproduce makes this system very flexible and cannot be handled by a rigid and bureaucratic system for dealing with illegal logging. It is suggested that the system for dealing with illegal logging must also be transformed into one of an autopoietic nature through collaborative management.

Abstract

Rural ethnic minority groups in Cat Tien National Park (CTNP) have relied heavily on non-timber forest products (NTFPs) and threatened its natural forest environment. Still, the real context of the NTFP consumption between indigenous peoples (IPs) and migrant ethnic minority group (MEs) has been poorly comprehended. Also, the participatory rural appraisal (PRA) and the “walk-in-the-wood” method were applied to analyse the NTFP consumption between these IPs and these MEs. The study results indicated that the two local groups had a high or a relatively high dependence on the NTFPs and there was a shifting trend from subsistence to cash income (p-value = 0.000 < 0.05). Also, these IPs had a better knowledge about edible forest plants than these MEs, whilst various more MEs consumed forest fauna for medicinal demand. These MEs harvested and consumed those NTFPs more intensively, but these IPs did the resources for more self-consumption related to the indigenous traditions. Based on the local context, NTFP use patterns, cultural dissimilarity, and local capacity empowerment remain needed in park administration strategies. Similarly, culture-based arrangements would contribute to positive outcomes and sustainable management of the park.
