Abstract

The ecotourism is global issues who most talked lately in Indonesia, it is one of the activities special tourist interest which low impacts on natural tourism.The presence of ecotourism in the era of sustainable and tourism development mission should be minimum negative impacts, both on the environment resources and on socio-cultural local values. Ecotourism activities were more oriented on the utilization of natural resources, the natural ecosystems and have not been polluted yet. However, when all of tourism development can not be separated from the negative impacts, such as ecosystem distress in ecotourism object when visited by large number of tourists, there are many conflicts of interest between the ecotourism management with local communities, especially regarding the benefits sharing and its accessibilities. The purpose of this paper is to identify the environmental impacts arising as a result of ecotourism activities and to find out alternative efforts in mitigating the environmental impact of ecotourism activities. Carrying capacity of ecotourism is not just limited to the number of visits, but also covers other aspects, such as: (1 ) ecological capacity that is ability of natural environment in providing the needs of tourists, (2) physical capacity, that is ability of facilities and infrastructure in providing the needs of tourists,  (3) social capacity, that is ability to absorb tourism activities without the negative impacts on the local communities, (4) the economic capacity, that is ability to absorb destination commercial efforts and accommodateany interests of the local economy. Keywords: Ecotourism, environmental impacts, carrying capacity.

Abstract

Tourist arrival and its effects on the sustainability of biodiversity in Sulawesi is one of the interesting public issues discussed at this time. Object of the most visited by tourists are protected forest ecotourism. In a protected forest tour are endemic plant and animal species that must be protected and preserved in order to sustain their ecosystem. Forest ecosystem suggests the dynamic interactions between plants, animals, and microorganisms and their abiotic environment working together as a functional unit. Ecosystems will not sustain if they are imbalance. However, thare are many human activities, especially tourist activities lead to major implications on biodiversity of natural vegetation in Sulawesi. This paper presents informations and data on vegetation biodiversity and information about tourist activities in maintaining vegetation biodiversity. There are 57 endemic plant species in Sulawesi are still maintained and preserved. Most are in Gorontalo about 16 species, in North Sulawesi about 13 species, in Southeast Sulawesi 10 species, in Central Sulawesi 9 species and in South Sulawesi, 9 species. Activities carried tourists in maintaining diversity of species include: planting trees, learning and research the endemic species of plants and animals, and collect solid wastes in the tourism areas. These activities suggest a positive impact on the sustainability of forest ecosystems and economic benefits for the local communities. Keyword : Tourist activities, biodiversity, endemic species.

Abstract

This study aims to analyze the tourists' perception about the importance and satisfaction on the product of fisheries tourism, and to assess the visiting time of tourist based on climate conditions. The research was conducted in May to June 2013 in Ngebel Lake, Ponorogo. We used descriptive quantitative approach, with 45 respondents. Data collected from interview, questionnaire and observation. Analytical methods were used to determine the perception of tourists on the satisfaction and interest in fisheries tourism products, i.e. Importance Performance Analysis (IPA). We also used Tourism Climate Index (TCI) to determine the visiting time of tourist. The results show the value of satisfaction and tourist interest is low, therefore the improvement of several aspects become important. It is encompasses: a) the existence of parking area; b) the condition of Ngebel Lake; c) planning and management system, the condition of the local community; and d) activities of fish course restaurant and fish farming system of floating net cages. TCI value indicates ideal conditions for tourists traveled in Ngebel Lake is in November (convenience index value of 106), in December (97) and in April (94). This appropriate time to visit Ngebel Lake is expected to create a good impression for the tourists and enjoy the various fisheries activities in Ngebel Lake.

Abstract

High-traffic highway crossing agricultural fields impacts the quality of food crops grown on Vertisol agricultural fields in Pasuruan. Lead (Pb) released from the exhaust of motor vehicles into the air can eventually enter the soil and be absorbed by plants. This study aimed to examine the effect of Pb from exhaust motor vehicles emission on the Pb status and its behavior in soil, water, and plants. The study was initiated by conducting a survey to determine the sampling locations in selected inundated paddy and maize cropping systems. A stratified random sampling method was used to collect soil, water, and plant samples. The soil of the study area is dominated by Vertisol, with clay content ranging from 54% to 76%. The soil attributes a high cation exchange capacity ranging from 80.53 meq 100 g-1 to 93.57 meq 100 g-1. Pb emitted from 2,913,000 vehicles within four months period that entered the agricultural field was not absorbed by paddy and maize crops. Pb entered the soil in the adsorbed form, and no Pb was observed in the soluble form, so it was not absorbed by the roots. In the paddy field, the total Pb of 84.33% was influenced by pollutant distance. Likewise, in the maize field, 83.18% of total Pb was influenced by pollutant distance. The far the pollutant distance from the agricultural field, the lower its total Pb. Paddy field water is adsorbed onto the colloidal clay, which is dispersed due to inundation and sloughing of the paddy, moving with the clay and then dissolved in the water flow.

Abstract

Peningkatan jumlah Daerah Aliran Sungai (DAS) kritis termasuk DAS Brantas adalah salah satu masalah utama yang harus diselesaikan dalam pengelolaan lingkungan di Indonesia. Untuk menyelesaikan permasalahan ini diperlukan solusi dengan pendekatan perencanaan pengelolaan DAS secara terpadu. Dalam penyusunan perencaan tersebut, landasan berfikir pemangku kepentingan merupakan fundamen penting yang harus perhatikan. Penelitian ini bertujuan untuk menganalisis landasan berfikir pemangku kepentingan untuk penyusunan perencanaan pengelolaan sub DAS Brantas hulu wilayah Kota Batu. Metode yang digunakan adalah metode survei dengan pendekatan kuantitatif. Analisis data dilakukan melalui metode Profesional Judgement dengan menggunakan analisis Ziel Orientierte Projekt Planung (ZOPP). Hasil penelitian ini menunjukkan kalau landasan berfikir penyusunan perencanaan pengelolaan sub DAS Brantas hulu wilayah Kota Batu terdiri atas 4 tahap, yaitu: analisis pemangku kepentingan, analisis masalah, analisis tujuan dan analisis penyelesaian masalah. Faktor pendorong utama untuk penyusunan rencana pengelolaan sub DAS Brantas hulu antara lain adalah adanya komitmen dari pemangku kepentingan, sementara faktor utama penghambatnya adalah belum adanya koordinasi dari pemangku-pemangku kepentingan tersebut. Penelitian ini menunjukkan kalau tersusun dan terdokumentasinya landasan berfikir dalam penyusunan rencana pengelolaan sub DAS Brantas hulu wilayah Kota Batu menjadi hal yang sangat penting untuk kepentingan berbagai pihak seperti legislatif, eksekutif, yudikatif, swasta, tokoh masyarakat, perguruan tinggi dan lembaga swadaya masyarakat. Saran yang diberikan dari hasil penelitian ini adalah perlu adanya perubahan pola berfikir dalam penyusunan rencana pengelolaan dari sektoral menjadi terpadu dan dari reaktif ke antisipatif.

Abstract

Monitoring  lemon production requires appropriate and efficient technology. The use of UAVs can addressed these challenges. The purpose of this study was to determine the best vegetation indices (VIs) for estimating chlorophyll content, plant height (PH), canopy area (CA), and fruit total numberas (FTN). CCM 200 was used as a tool to measure the chlorophyll content index (CCI), the number of fruits was measured by hand-counter, and other variables were recorded in meters. The UAV used was a Phantom 4 with a multispectral camera capable of capturing five different bands. The VIs was obtained via analysis of digital numbers generated by the multispectral camera. Then, the VIs was correlated with the CCI, PH, CA and FTN. VIs tested included the following: the normalized difference vegetation index (NDVI), the normalized difference vegetation index-green (NDVIg), the normalized different index (NDI), green minus red (GMR), simple ratio (SR), the Visible Atmospherically Resistant Index (VARI), normalized difference red edge (NDRE), simple ratio red-edge (SRRE), the simple ratio vegetation index (SRVI), and the Canopy Chlorophyll Content Index (CCCI). The best model for predicting CCI was obtained using the NDVIg (R2=0.8480; RMSE=6.1665 and RRMSE=0.0908). Meanwhile, SR turned out to be the best model for predicting PH (R2=0.8266; RMSE=15.6432 and RRMSE=0.0883), CA (R2=0.6886; RMSE= 0.8826 and RRMSE=0.1907), and FTN (R2=0.6850; RMSE=24.5574 and RRMSE=0.3503). The implication of these results for future activities includes establishing early monitoring and evaluation systems for lemon yield and production. This model was developed and tested in this specific location and under these environmental conditions.

Abstract

Upland rice productivity in rainfed drylands of Eastern Indonesia remains constrained by severe soil degradation and suboptimal agronomic management. This study evaluated the combined effects of rice husk biochar (0, 5, 7.5, and 10 t ha-¹) and four upland rice genotypes on soil fertility improvement and growth dynamics across three physiological phases. A factorial randomized complete block design with three replications was implemented in Majene Regency, West Sulawesi. Results showed that biochar selectively improved the most degraded soil properties, increasing organic C (+13.4%), total N (+20-27%), and available phosphorus (+26.6%), while exchangeable potassium and C/N ratio remained unchanged. Soil improvements were consistent across genotypes, as no significant genotype × biochar interaction was detected. However, growth responses were strongly genotype-dependent, with significant interactions observed for plant height, tiller number (p<0.05), and crop growth rate (p<0.01). Temporal analysis identified the peak vegetative phase as the critical window for treatment differentiation. The Asseang genotype exhibited superior performance, achieving the highest plant height (115.7 cm), tiller number (21.3), and crop growth rate (9.12 g m-² day-¹). The optimal biochar dose was 7.5 t ha-¹, beyond which growth responses plateaued, highlighting the need for integrated genotype–biochar strategies for sustainable intensification.
