Abstract

Lumajang is one of the regency in East Java Province that has various types of freshwater ecosystems and have great potential as habitats for various insects, especially dragonflies. Dragonflies are insects that mostly live aquatically, so their existence is highly dependent on the condition of aquatic ecosystems. This study aims to compare the composition and diversity of dragonfly species in various habitat types in Lumajang. The study was conducted in lentic and lotic ecosystems in Lumajang. The method used was the Visual Encounter Survey (VES) technique adapted from the sweeping net. The data analysis used to determine differences in dragonfly species composition was the Bray-Curtis similarity analysis, while diversity analysis was conducted using the Shannon-Wiener index. This study recorded 29 species from seven families, including seven endemic dragonfly species found only on several islands in Indonesia. In the analysis of the Shannon-Wiener diversity index, the results show that in all research locations have a value of H'= 1.07‒2.11, where the Rice Field habitat is the location with the highest value among other locations, with a value of H' = 2.11. The similarity analysis of dragonfly species composition using Bray Curtis similarity showed that it was divided into three groups. The composition of dragonflies found in several habitats in Lumajang is different, which can be influenced by many factors such as site elevation, habitat type (lentic or lotic), and habitat condition, as well as several other factors such as microclimate and vegetation (related to food availability).

Abstract

Fruit flies are important pests of citrus crops. Identifying fruit fly species is very important to make the appropriate conclusions in determining controlling methods. This study was intended to establish the dominant species, diversity index, and identification of fruit fly species in Siam citrus (Citrus nobilis Lour.) orchards in Dau District, Malang Regency, Indonesia. This study was conducted in two habitat types: close and far from residential areas. Six petrogenol-treated traps were placed at each location from December 2022 to February 2023, and every two weeks, the fruit flies caught in the traps were counted as part of the survey. The results showed that three species, namely B. dorsalis, B. carambolae, and B. umbrosa, were found in locations close to residential areas, while B. umbrosa was not found in locations far from residential areas. The dominant species was B. dorsalis in both locations. The diversity index of Bactrocera spp. in orchards close to residential areas was 1.14 (moderate), and Spearman's analysis (0.913) showed a more substantial influence than in orchards far from residential areas. Climatic factors of air humidity, air pressure, and host availability play an essential role in the presence of fruit flies.

Abstract

The community service activity in the Kasembon area was focused on the community of Sukosari Village, Kasembon District, which has significant potential in product development through local SMEs. However, the lack of knowledge and skills in halal production and certification has become an obstacle. Therefore, this activity aims to improve the knowledge and skills of business actors in halal product processes and slaughtering techniques. The methods used include site surveys, involving the Kasembon Business Destination Association (PADUKA), followed by education and mentoring. The activity was attended by 20 participants, consisting of business actors and prospective halal slaughterers. Based on the results, it can be concluded that education/presentation increased the participants' knowledge, motivation, and interest in implementing halal product processes and certification in Kasembon SMEs. The participants' initial knowledge regarding halal product process criteria was quite good, but many were still unaware of the differences between self-declaration and regular certification, the Halal Product Assurance System Manual Document, halal slaughtering processes, and marketing strategies. With counseling and training, participants' knowledge and awareness increased significantly. As a result, participants' understanding increased from 15-60% to 30-50%, with a satisfaction rate of 50% being very satisfied, 45% satisfied, and 75% committed to following up, developing, and supporting halal product certification in Kasembon. Keywords: halal product; halal certification; UMKM.

Abstract

Hubungan antara kondisi oseanografi dan kelimpahan ikan lemadang (Coryphaena hippurus) di Perairan Selatan Jawa merupakan aspek penting dalam memahami dinamika habitat dan pengelolaan perikanan berkelanjutan. Penelitian ini bertujuan untuk menganalisis pengaruh suhu permukaan laut (SPL) dan konsentrasi klorofil-a terhadap kelimpahan ikan lemadang di wilayah tersebut. Studi ini didasarkan pada analisis data penangkapan ikan selama periode 2019-2023 dan dinamika parameter lingkungan di Perairan Selatan Jawa. Observasi SPL dan klorofil-a dilakukan melalui teknologi penginderaan jauh. GAM dipilih untuk mengidentifikasi ambang batas dari masing-masing parameter dan hubungan empirisnya dengan CPUE ikan lemadang. Hasil penelitian menunjukkan bahwa SPL dan klorofil-a memiliki pengaruh yang signifikan terhadap kelimpahan ikan lemadang. Kisaran optimal SPL dan klorofil-a untuk ikan lemadang masing-masing adalah 25,5-30,57° C dan 0,04-1,33 mg/m3. Dengan demikian, temuan ini dapat memberikan wawasan mengenai preferensi habitat ikan lemadang di Perairan Selatan Jawa.   The relationship between oceanographic conditions and the abundance of dolphinfish (Coryphaena hippurus) in the Southern Java Waters is essential in understanding habitat dynamics and sustainable fisheries management. This study aims to analyze the effects of sea surface temperature (SST) and chlorophyll-a concentration on the abundance of dolphinfish in the region. The study is based on the analysis of fish catch data from 2019 to 2023 and the dynamics of environmental parameters in the Southern Java Waters. SST and chlorophyll-a observations were conducted using remote sensing technology. The generalized additive model (GAM) was chosen to identify the thresholds of each parameter and their empirical relationship with the dolphinfish CPUE. The results show that SST and chlorophyll-a significantly influence dolphinfish abundance. The optimal ranges for SST and chlorophyll-a for dolphinfish are 25.5–30.57 °C and 0.04–1.33 mg/m³, respectively. These findings provide valuable insights into the habitat preferences of dolphinfish in the Southern Java Waters.

Abstract

Landslides can cause soil and land quality degradation. Soil originating from landslide sites has less stable aggregates because it is nutrient-poor. This study aimed to evaluate the effect of hydroseeding media materials on soil stability after landslides. This study was conducted in two landslide areas in Pujon District, Malang Regency (112.417958 E, 7.867472 S) and toll road KM 78 Purwodadi, Pasuruhan Regency (112.726777 E, 7.804978 S), East Java. Soil analysis was carried out with parameters including soil physical characteristics data (bulk density, specific gravity, water content, porosity, texture and permeability) and soil chemical characteristics (organic matter, organic C, N, P, K, pH, CEC, exchangeable K, Na, Ca, Mg, total N and C/N ratio). The application of hydroseeding media was carried out with a combination of the following media: mulch (M), blotong (B), and fertilizer (cow manure; F). The results showed that the two-material formula generally had soil aggregates that were more resistant to water droplets. Soil aggregates with the MB formula treatment had the best aggregate stability compared to ten hydroseeding formulas with other material combinations.

Abstract

Natural sacred sites are areas that possess cultural and spiritual significance within the community. The village forest around the Sumber Sirah is a natural sacred site. Currently, part of the forest area has changed its function to become a tourist area integrated with spring tourism. This may lead to changes in the structure and composition of the vegetation in the area. The purpose of this study was to analyze the structure of the vegetation composition between natural and changed vegetation for tourism activities. This research was conducted in Putukrejo Village, Gondanglegi District, Malang Regency, East Java. Data collection was carried out by making 20 x 20 m2 sample plots for vegetation that has a tree habitus. 10 x 10 m2 for pole habitus, 5 x 5 m2 for sapling habitus, 2 x 2 m2 for seedling habitus and herb/ground cover. The results of the vegetation analysis then determine the importance value index (IVI), Shannon-Weiner index (H'), evenness index (E'), dominance index (id), and endemism (End). Based on the research results, the composition of plants differs between natural areas and tourist areas. Specifically, 35 species were identified in the natural area, while 20 species were found in the tourist area. The value of endemism in areas that are still natural for all habitus is in the high category, where the vegetation composition is generally found in lowland forests. In contrast, the composition of tourist areas is dominated by cultivated plants and some introduced species. The Shannon-Wiener diversity index, both natural and tourist, is in the moderate category. The evenness index falls within the moderate to high category, and the dominance index is classified as high.

Abstract

Purwodadi Botanic Garden is one of the botanic gardens in Indonesia, located in Pasuruan, East Java. Purwodadi Botanic Garden (PBG) is an ex-situ plant conservation area that serves five main functions: conservation, research, education, ecotourism, and environmental services. Purwodadi Botanic Garden features a living collection of plants, primarily terrestrial, but also includes aquatic species. Therefore, this study aims to conduct water quality monitoring in aquatic plant ponds and present the experiments of phytoremediation on selected species of aquatic plants. This research employs a mixed-methods approach, combining qualitative and quantitative methods. Data were obtained from direct observation of aquatic plants in the garden, monthly monitoring of water quality in 32 ponds, and the results of phytoremediation experiments from research activities spanning over ten years. Monitoring water quality using water-test kits is inexpensive, easy to use, and yields results quickly. Parameters measured for environmental quality are temperature, humidity, light intensity, pH, TDS, and water temperature. The results show that, out of 32 ponds in the garden, only 12 ponds were found to have aquatic plants. The water quality in ponds with aquatic plants is generally better than in those without aquatic plants, indicating that the aquatic plants in ponds act as phytoremediators in the effort to improve water quality. Purwodadi Botanic Garden contains 25 species of aquatic plants. However, during the observation of the pond, only 15 species of aquatic plants were present. The results of the experiments selected 10 species as phytoremediation agents for both organic and inorganic pollution. The 10 species are Acanthus ilicifolius, Actinoscirpus grossus, Ceratophyllum demersum, Coix lacryma-jobi, Echinodorus radicans, Lemna minor, Ludwigia octovalvis, Pistia stratiotes, Sagittaria lancifolia, and Salvinia molesta.

Abstract

Coal mining is an activity that contribute to greenhouse gas emissions, both from methane gas release of coal trap and the loss of lan cover plants. This study was conducted to estimate carbon emissions in coal mining areas inside forest areas by analyzing changes in landcover. The area of this study is Kutai Kartanegara Regency, East Kalimantan, where coal mining activities are quite massive. To obtain the extent of changes in land cover and the amount of carbon emissions in the area, analysis of Landsat 5 TM and Landsat 7 ETM+ imagery in 2010 and also the 2016 Landsat 8 OLI / TIRS imagery was used. The results showed that in the area of study there was a change in landcover of 12,663.28 Ha in the forest areas used for coal mining activities. Carbon emissions generated from this activity amounted to 0.60 Mton CO2-Eq
