Abstract

ABSTRACT The concept of sustainable tourism which prioritizes environmental, natural and cultural preservation is known as "ecotourism". Mangroves are a unique ecosystem that has a lot of diversity and beauty. The presence of mangrove ecotourism in the community can have a positive impact and play an important role in ecosystem life. Therefore, community perception, motivation and participation are important factors that determine the existence of ecotourism in an area. Positive perceptions can encourage active community participation in conservation activities, environmental education and ecotourism development. On the other hand, negative perceptions or lack of understanding can become obstacles in environmental conservation efforts. This research was carried out for 3 months in the Kano Maritim Baros Mangrove Ecotourism area, Bantul Regency, Special Region of Yogyakarta. This research aims to see and analyze the perceptions, motivations and participation of communities involved in mangrove ecotourism in Kano Maritim Baros. To process respondent data, this research uses a Likert scale and correlation analysis. The number of respondents in this study was fifty. The results of this study show that the three variables tested for correlation do not have a significant correlation with each other. Apart from that, the perception, motivation and involvement of the community towards the existence of the Kano Maritim Baros mangrove ecotourism is categorized as "Good".

Abstract

This research aims to determine the influence of organic stimulants and stimulant concentrations on pine resin production, to obtain alternative stimulants that are safe for the environment and can also increase pine resin production. The research design used a Completely Randomized Design (CRD), with a factorial experiment consisting of two factors, namely the organic stimulant type factor which consisted of 3 levels, namely the stimulant extract of shallots, ginger and galangal and the stimulant concentration, which consisted of 3 levels, namely 100% concentration. , 75% and 50% plus control, so there are 9 treatment combinations. Replication was carried out 6 times so that 54 tree samples were obtained plus 6 control trees, or a total of 60 tree samples. The results of the research showed that the average production of pine resin in the stimulant treatment types of onion, ginger, galangal and control extracts was 76, 28 grams, 76.28 grams, 140.06 grams and 21.23 grams, respectively. The results of the variance analysis show that the type of stimulant shows a very real influence, while the concentration of the organic stimulant shows an insignificant influence. Further test results showed that the organic stimulant galangal extract had a significant difference from the organic stimulants of ginger and shallots, while the organic stimulants of shallots and ginger showed no significant differences. The research results also showed that the sap production of the onion and ginger extract stimulant treatment showed sap production that was not significantly different from the control, however, the galangal extract stimulant treatment showed a significant difference.

Abstract

Anthocephalus cadamba Miq., is a type of tree from South and Southeast Asia which is currently widely cultivated by the community. Jabon has various uses such as block board and particle board. Apart from that, this plant is also known as a fast growing plant. Jabon farmers have their own way of caring for their plants, on of which is plant spacing. The goal of this research was to ascertain the impact of planting distance on survival rate and growth (height and diameter) of 1 year old Jabon plants in Temanggung Regency, Central Java. Data collection was carried out by taking 50 samples in each field consisting of 2x2 m, 3x3 m, and 4x4 m spread across 3 villages in Temanggung Regency. The replicates used were individual Jabon plants. Data from the research results were analysed using by analysis of variance, and tested further using the LSD test. The research results showed that land with a planting space of 3x3 m had a higher percentage of jabon plants than the land with a planting space of 2x2 m and 4x4 m, namely 71%. Land with a planting space of 2x2 m produce a better average height and diameter of jabon plants than of 3x3 m and 4x4 m, namely 1,39 m for height and 1,97 cm for diameter respectively.

Abstract

One of the causes of critical land is erosion; the greater the intensity of erosion, the more critical the land becomes. The distribution of erosion predictions is influenced by variables such as rainfall erosivity, soil erodibility, slope length and steepness, ground cover vegetation, land use, and land conservation. One of the critical lands is located in Kapanewon Panggang, Gunungkidul Regency, Special Region of Yogyakarta, covering an area of 9130.01 hectares, which consists of six villages: Giriharjo, Girisuko, Giriwungu, Girimulyo, Girikarto, and Girisekar. The purpose of this study is to determine the erosion rate in Kapanewon Panggang, to assess the level of erosion hazard in Kapanewon Panggang, and to formulate a land management concept based on actual land use conditions with erosion criticality parameters in Kapanewon Panggang, Gunungkidul Regency, Special Region of Yogyakarta. The method used is the USLE (Universal Soil Loss Equation). USLE is an erosion model designed to predict long-term erosion from sheet or rill erosion under specific conditions. USLE is used on both agricultural and non-agricultural lands. The results show that the erosion hazard levels in Kapanewon Panggang are categorized as very light (1184.28 hectares), light (1074.65 hectares), moderate (1831.70 hectares), severe (2411.01 hectares), and very severe (2628.38 hectares). The factors that most influence the magnitude of erosion are land use, slope length, and steepness. The land management concept to minimize erosion can be implemented based on land cover, namely in residential areas where water infiltration areas are needed, in savanna land use where additional vegetation and ground cover plants are necessary, and based on slope length and steepness, mechanical conservation by constructing bench terraces and stone bunds should be applied.

Abstract

One of the problems in cultivating Eucalyptus pellita seedlings in Industrial Plantation Forest (HTI) nurseries is the attack of Xanthomonas sp bacteria. Seedlings that are attacked by this bacteria will experience spots on the leaves, wilt, fall off, and ultimately cause the death of the seedlings. Controlling bacterial attacks by using bactericides is one effort to minimize bacterial attacks. The purpose of this research is to determine the effect of the type of bactericidal active components, namely Oxitetracycline, Zinc Thiazole, and Copper Oxside, and the spraying time interval on the growth of Xanthomonas sp on NA (Nutrient Agar) media, reducing the incidence and severity of bacterial attacks on E. pellita seedlings. The research used 2 treatments factor, namely kinds of bactericidal active component and spraying time interval. Test of bactericidal active component was carried out on laboratory (in-vitro) and direct testing on sedlings. The research results showed that bactericides with the active components Oxitetracycline, Zinc Thiazole and Copper Oxcide, were able to inhibit the growth of Xanthomonas sp on NA media. Oxitetracycline resulted in a higher reduction in the incidence and severity of Xanthomonas sp attacks on E pellita seedlings compared to other active ingredients, namely 61.36% for a reduction in incidence and 36.25% for a reduction in severity. The bactericide spraying time interval of 1 and 2 weeks did not have a significant effect on reducing the incidence and severity of Xanthomonas sp attacks on E. pellita seedlings.

Abstract

The people of Widodomartani mostly have agricultural land that is managed independently. One of the agricultural land management practices carried out is sengon and cassava agroforestry. Cassava in addition to being taken from the tubers and leaves for vegetables can also be used for the cultivation of samia ricini silkworms. Cassava is usually planted on the sengon path on the guludan path. The planting distance of sengon is 2m x 2m while the distance between yams is 2m x 0.7 m or between sengon there are 3 cassava. This study aims to determine life cycle of Samia ricini silkworms, the production of cassava leaves and their potential for the cultivation of Samia ricini silkworms. The method used was to take samples of cassava plants to calculate the number of stalks, calculate the weight of the leaves and convert the feed needs of Samia ricini caterpillars and to known life cycle of Samia ricini silkworms. The results of the study obtained for life cycle of Samia ricini silkworms 53-61 days (eeg fases 7 days, 21-30 days caterpillars/larva, 17 days cocoon/pupae, and 8 days imago/silkworms) and an average leaf production per cassava plant of 123,466 leaf stalks. The number of plants per ha is around 7,142,857 plants. The potential production of the number of thigh leaves is 881,899,982 stalks. The average weight of 1 petiole is 4.06 grams (average 2.786 grams without stalk). The feed requirement of 1 large caterpillar is 15.3097 petioles / 62.157 gr (42.6528 gr without stalk). One hectare of sengon and cassava agroforestry land can support the cultivation of 57,603,348 samia ricini caterpillars. The average weight of one cocoon is 2.10 grams and silk (cocoon not pupae) 0.28571 gr (13,6%). One ha of land can support the production of silk cocoon as much as 120,967,030 gr or 120,967 kg.

Abstract

This study aims to analyze changes in vegetation density in Gunungkidul Regency using the NDVI (Normalized Difference Vegetation Index) method based on Landsat 8 satellite imagery. The research focuses on evaluating the condition of teak forest vegetation density in Gunungkidul Regency in 2013 and 2023, with the goal of identifying land cover changes and providing an overview of the forest ecosystem conditions in the area. The methods used in this research include processing satellite imagery with spatial analysis techniques using GIS (Geographic Information System) software. NDVI data was analyzed to measure vegetation density for both time periods, classifying land cover into several categories: non-vegetated land, very low vegetation, low vegetation, and moderate vegetation. The analysis results were compared to identify trends in changes over the ten-year period. The findings indicate that there has been a change in vegetation density in Gunungkidul Regency, with a decrease in the area of low vegetation from 126,747.87 hectares in 2013 to 118,972.88 hectares in 2023 (6,13%). An increase in non-vegetated land was also recorded, rising from 513.47 hectares to 1,107.76 hectares during the same period (113,24%). Although there were some improvements in vegetation density, the increase in non-vegetated land indicates challenges in land management in the region.
