Abstract

Textile waste consists of insoluble solid particles, salts, dyes and heavy metals and is very difficult to degrade. Chitin derived from shrimp waste has the potential to overcome textile waste in chitin that causes environmental pollution through more economical absorption and easily available raw materials. Factors that improve adsorption performance include pH and temperature. This study was conducted to determine the effect of temperature, pH, and a combination of temperature and pH treatments on the ability of chitin to adsorb textile dye waste. The parameters observed were temperature, pH, combination of temperature and pH, functional groups (FTIR), chitin structure (SEM), and heavy metal test (AAS). Data analysis of statistical test results using two-way Analysis of Variance (ANOVA) followed by Duncan's further test. The ANOVA test results showed that the incubation treatment of temperature, pH, and a combination of different temperature and pH treatments resulted in (p < 0.05). This shows that incubation temperature and pH have an effect (significantly different) on the adsorption of chitin as an adsorbent on dyes. The results of Duncan's test showed that the best chitin adsorption was obtained in temperature incubation at 50°C (A3), incubation at pH 3 (B1), and the best combination adsorption at 50°C and pH 3 of 1,091±0.007a ppm.

Abstract

Makassar City, located on the southwest coast of Sulawesi Island, exhibits dominant land and sea breeze circulation, with sea breezes being stronger during the day and land breezes at night. The use of weather radar is effective in identifying these wind characteristics, which are crucial for fishing activities and renewable energy. This study investigates the characteristics of land and sea breezes and their relation to wave heights in the Spermonde Waters of Makassar during the east and west seasons, providing important information for maritime activities in Makassar City. The research area is located between 4°59’20”S 119°27’46”E and 5°11’26”S 119°22’54”E. This study uses weather observation data, including weather radar data, weather observations, and wave heights from January 2020 to December 2020, divided into three seasonal periods (rainy season, transition period, and dry season). The weather observation data were obtained from Hasanuddin Makassar Meteorological Station and Paotere Makassar Maritime Meteorological Station. Additionally, questionnaires were distributed to fishermen at three locations: PPI Paotere Makassar, PPI Untia Makassar, and Kuri Caddi-Maros Beach Fishermen Village, with 15 respondents at each location. The study shows that land breezes in Makassar are dominant from 18:05 to 19:00 LT with a duration of 9.1 to 11 hours, while sea breezes dominate from 08:00 to 09:00 LT with a duration of 5.1 to 7 hours. This phenomenon is most frequently detected during the dry season (JJA). Land and sea breezes can intrude up to 20.1 to 30 km from the coastline. There is a highly significant positive correlation between wind and wave height in January and August, indicating a strong influence of winds on waves in the Spermonde Waters of Makassar. About 80% of fishermen utilize these wind conditions for fishing activities. Overall, the land and sea breeze patterns significantly impact wave heights and the activities of fishermen in the coastal areas of Makassar.

Abstract

Rural landscapes are part of man-made landscapes as a result of conversion of natural landscapes due to human needs. Birds respond positively to these changes as ecosystem components that are able to adapt and survive in rural landscapes. The countryside in the northern part of the Sukabumi is located between the natural landscape of Mount Gede and the rural landscape of Sukabumi City. The research aims to analyze the diversity of bird in the rural landscape of the Sukabumi Area. Research in the form of direct observation was carried out in February-May 2022.  Bird data was taken using the point count method in the morning and evening. Qualitative analysis was carried out by describing and looking at the protection status. Quantitative analysis was carried out using (1) chi-square test, (2) Margalef Index (DMg), (3) Shannon-Wiener Index (H'), (4) venness index (E), and similarity index community (IS). There were 43 species of birds found from nine orders and 23 families. Five species birds are protected by the Indonesian Government. A total of 25 species (58%) are members of the Order Passeriformes. The majority are terrestrial birds, there is only one species that is considered a water bird, namely Von Schrenck’s Bittern (Ixobrychus eurhythmus).

Abstract

The majority of Indonesian people consume rice as a staple food. According to data from the Central Statistics Agency (2022), rice production in West Sumatra reached 1,482,996.01 tons in 2019 and continued to decline until 2021, total rice production in West Sumatra was only 1,317,209.38 tons. This is inversely proportional to the population of West Sumatra which increases every year, so efforts need to be made to increase rice production. One of them is the biopriming technique to increase seed vigor. Priming is hydration carried out slowly which aims to ensure that the seed's water potential reaches balance and activates metabolism in the seed before the seed germinates. One of them is biopriming, which is a seed priming technique using biological agents in the form of beneficial microorganisms. Several factors influence the success of the priming technique, one of which is the soaking time. The right soaking time provides a deeper opportunity to absorb water to stimulate the seeds to germinate. This research aims to determine the effect of soaking time on biopriming of the local West Sumatran rice variety "Anak Daro" using Bacillus subtilis and Trichoderma harzianum on the germination of the Anak Daro rice variety. Completely Randomized Design (CRD) factorial pattern with 2 factors with 3 replications. Factor A is a biopriming agent, namely A1 (no microbes), A2 (Bacillus subtilis), and A3 (Trichoderma harzianum). Factor B is the length of soaking, namely B1 (24 hours), B2 (48 hours), and B3 (72 hours). The results showed that Bacillus subtilis and Trichoderma harzianum had a significant effect on maximum growth potential and germination, while soaking time had a significant effect on maximum growth potential and vigor index.
