Abstract

Macrozoobentos are known as organisms that are sensitive to environmental changes, so they are widely used as biological indicators of a water. This study aims to determine the types of macrozoobenthos, the level of diversity, uniformity, and dominance of macrozoobenthos, including the family biotic index (FBI) to detect water quality in Dumai City. The method used was a survey with stations determined through the purposive sampling. Macrozoobenthos samples were collected using a line transect with a square transect and a core sampler. A total of 381 macrozoobentos individuals found in the waters of Dumai City consisted of 6 species from the Gastropods class (Nerita articulata, Chicoreus capucinus, Littorina scabra, Ellobium aurisjudae, Cerithidae quoyii, and Pugilina cochlidium); Bivalvia class: 1 family and 1 species (Polymesoda bengalensis). The highest macrozoobenthos density was found at Station 3 (125 ind/m2) and the lowest at station 1 (21 ind/m2). The Shannon-Wienner diversity index ranged between 1.17 and 1.52. The diversity index at all stations was relatively low, the macrozoobenthos uniformity index was high (0.654697-to 0.783512), and the dominance index was relatively low (0.234078-to 0.43574). The Shannon-Wienner Index and the dominance index are also relatively low. Further testing using the FBI showed differences in water quality: Station 1 was adequate, Station 2 was poor, while Station 3 was somewhat poor. Monitoring macrozoobenthos diversity can be helpful in detecting changes or disturbances in ecosystems. Keywords: bioindicator, diversity, Family Biotik Index, macrozoobenthos

Abstract

This house yard (pekarangan) research was conducted at three sites of the Way Seputih-Sekampung watershed, which are represented by the upstream (Mulyosari Village), middle (Margodadi Village), and downstream (Tejosari Village), Metro Municipality, Lampung Province from May to July 2022. The objective of this research is to analyze the yard as a productive landscape by analyzing: 1) plant composition, 2) the diversity of plant species, and 3) utilization of the yard. Surveys and questionnaires were used. The number of yards was determined by purposive sampling, totaling 30 yards belonging to members of the Women Farmers’ Group (KWT) at each location. The results showed that horizontal diversity includes ornamental, fruit, vegetable, medicinal, and starch-producing plants. Sixteen types of plants were frequently found in 46% of yards. It was found that the Shannon-Wiener species diversity decreased from upstream to downstream, that is, upstream (2.41), middle (2.33), and downstream (1.82). Although the diversity of plant species is moderate on average, communities use their yards according to their function. The community was aware of the benefits of the yard, particularly its contribution to environmental sustainability, as indicated by the assessment index for the upstream (87%), midstream (93%), and downstream (94%) sites. Thus, the yard is very useful for the community as a place for interaction during the Covid-19 pandemic. Such benefits are said to be better if landscape management is carried out in a planned and environmentally friendly manner. Keywords: community, home garden utilization, landscape management, pandemic, species diversity

Abstract

The purpose of this study is to catalog exceptional durians from both the highlands and the lowlands of Fakfak Regency in West Papua Province. The inventory included both highland and lowland durian accessions. In the highlands, there were 8 durian accessions, whereas in the plains there were seventeen. Fruit size, fruit skin thickness, fruit pulp color, fruit pulp thickness, aroma, sweetness level, fruit pulp fiber, seed size, and seed count were utilized as evaluation criteria. Each criterion tested showed variability. This demonstrates that genotypic variability exists among durian accessions from the Fakfak Regency. According to the characterization results, there were six lowland accessions that could be classified as superior in terms of fruit size, thickness of fruit pulp, level of sweetness, pulp fiber, and aroma: Pahger Nkendik, Katemba, Danaweria2, Brongkendik, Air Besar, Kanantare, and Sakartemin. Keywords: durian, Fakfak, superior fruit

Abstract

The Bogor Botanical Gardens' Mexican Park presents various dry-climate plants useful for recreation and learning. The presence of weeds in the collection site would have a negative impact because they can inhibit the growth of the collection plants. This study examined the diversity of weeds in the Mexican Park, Bogor Botanical Gardens. This descriptive study took place in the Bogor Botanical Gardens, specifically in the Mexican Park, and weed identification was carried out at the National Research and Innovation Agency. The weed data obtained was then analyzed descriptively through a literature study. The results showed that there were 52 weed species from 28 families. Most species came from the Asteraceae and Araceae families. The block that had the most weeds was Block II.O.IV, with a total of 15 weed species. The species that were often found in each area of the Mexican Garden Collection include Euphorbia graminea Jacq., Euphorbia heterophylla L., Calliandra calothyrsusMeisn, Coleus monostachyus (P. Beauv.) AJ Paton, Cecropia peltate L., and Cissus verticillata subsp. verticillata. Keywords: Inventory, Weeds, Mexican Park, Bogor Botanical Garden

Abstract

The nilem fish (Osteochilus hasselti) is one of the most easily caught fish in Teluk Lake. Currently, cage farming activity in the lake slightly exceeds the water carrying capacity, which is suspected to affect the life of fish in the lake, including nilem. This study aimed to determine the condition factor and Gonadosomatic Index (GSI) of the nilem catch in the lake. This study was conducted from August to September 2023 in Teluk Lake. This research used a survey method with simple census sampling techniques. The analysis of the length-weight relationship of nilem fish obtained from Teluk Lake showed a positive allometric relationship with a value of b = 3.7148. It showed that the increase in body weight of nilem fish was not linear with the increase in length. The catch results by fishermen for nilem fish found a male-to-female sex ratio of 1:2.15, with 90% of the captured fish in a mature gonad condition. The GSI for females ranged from 3.20% to 8.33% and for males, from 0.03% to 28.89%. The first maturation size (Lm) for male fish was 125.847, with a size class range of 116–126 mm. For female fish, the first maturation size calculation resulted in 112.996 with a size range in the 104–113 mm class. Lm is smaller than the average size of the captured fish, indicating that it is safe to catch, and there is a low likelihood of recruitment overfishing.

Abstract

Ethnoecology is a science that studies the relationship between humans and the environment. This relationship is related to the use of natural resources around them to continue life using local wisdom, namely the agroforestry system. Ecologically, economically, and socially, the agroforestry system planting patterns can help reduce soil fertility degradation due to human activities that exceed the carrying capacity of the land. The aim of the research was to determine land management and manifestations of land management for durian plants that implement the agroforestry system. The research used qualitative methods with techniques namely collecting data, analyzing data, and drawing conclusions. Data collection used snowball sampling techniques with an unlimited number of respondents. The results explain that (1) land management, tillage, fertilization, crop rotation, and fallow periods on durian plantations have not been managed optimally, resulting in the production of durian plants not being optimal; (2) the manifestation of land management is divided into two, namely traditional and semi-traditional agroforestry systems and these two systems have differences in land management, namely organic and non-organic. Keywords: agroforestry systems, durian, ethnoecology, land management

Abstract

Fedtugrow® is a complete feed containing depolarized katuk (Sauropus androgynous) leaves and is beneficial for enhancing the productivity of both dairy and beef cattle. Depolarization technology in katuk leaves involves the removal of polar compounds from the leaf to eliminate the potential side effects resulting from katuk consumption, such as bronchiolitis obliterans and inhibition of calcium absorption. This technology could eliminate side effects without compromising the efficacy of katuk leaves in increasing milk production and body weight gain. This study aimed to evaluate the efficacy of Fedtugrow® in promoting the growth of beef cattle and its impact on the health status of the cattle raised on smallholder local farms with distinct characteristics compared to commercial farms. Ten Limousin male cattle entering the fattening phase were divided into a control group that consumed standard concentrate and a treatment group that consumed Fedtugrow® for three months. Blood was collected at the end of treatment for hematological analysis, including erythrocyte and leukocyte profiles. Cows consuming Fedtugrow® showed a significantly higher average daily gain and lower stress index than the control. Furthermore, no significant differences were observed in the hematological profile, such as total erythrocyte count, hemoglobin level, hematocrit, and total leukocytes. This study showed the ability of Fedtugrow® as a growth promoter without negatively affecting the physiological status of beef cattle raised on smallholder farms. Keywords: Beef cattle, Fedtugrow®, hematology, smallholder local farm

Abstract

East Luwu Regency is one of South Sulawesi's regencies with potential in the plantation sector, especially cocoa plants, with a production of 12,250 tons/year. Cocoa productivity has yet to be achieved optimally due to the lack of care and maintenance carried out by farmers, which increases the intensity of pest & disease attacks. This study evaluates farmers' knowledge, attitudes, and actions in managing cocoa plants and plant pathogens in East Luwu Regency. This study was conducted through direct interviews using a structured questionnaire sent to 50 farmers in Burau and Wotu Districts, East Luwu Regency. Respondents were selected purposively, considering that they were easy to find and the location of the plantation was easy to reach. Data are presented in tabular, graphical, and descriptive forms in Microsoft Excel to explain the relationship between farmers' knowledge, attitudes, and actions in managing cocoa VSD disease. The results showed that most of the respondent were active farmer groups. Pests & diseases are problems farmers face in cocoa cultivation. Most farmers used the MCC 02 clone, and the planting distance was 3´3 m. The diseases most commonly found in farmers' cocoa fields include VSD, fruit rot, upas fungus, and stem cancer. Pest & disease control was done through chemical pesticides and pruning (cultivation techniques). Cocoa farmers in Burau and Wotu Districts routinely carry out pruning to control disease in cocoa fields. Farmers prune cocoa plants to remove diseased branches and stimulate the growth of flowers and fruit. Keywords: action, attitude, knowledge, questionnaire

Abstract

Lignin is a complex chemical heterogeneous polymer that forms a physical barrier to lignocellulose's biological and chemical hydrolysis, making lignocellulosic biomass challenging to degrade. Ligninolytic microorganisms play an essential role in lignin degradation by producing extracellular enzymes. Lignin peroxidase and manganese peroxidase are enzymes that play a role in lignin degradation. Forty-one bacterial isolates have been isolated from soil, kitchen waste, leaf litter, and cow dung. However, the ligninolytic activity of these isolates has yet to be discovered. This research aimed to determine the ligninolytic ability of bacteria isolated from soil, leaf litter, kitchen waste, and cow dung based on lignin peroxidase and manganese peroxidase activity. The study was conducted stages: isolate recultured, qualitative and quantitative testing of lignin peroxidase activity based on degradation of methylene blue dye, and qualitative and quantitative testing of manganese peroxidase activity based on degradation of phenol red dye. A total of four bacterial isolates from soil (Tn9, Tn14, Tn16, and Tn17) and two bacterial isolates from cow dung (KS2 and KS5) showed qualitative and quantitative lignin peroxidase activity. Manganese peroxidase activity was also shown by four isolates from soil (Tn2, Tn6, Tn14, and Tn16), one isolate from kitchen waste (SD1), and one isolate from cow dung (KS5) both qualitatively and quantitatively. The nine bacterial isolates that showed lignin peroxidase and manganese peroxidase activity have potential as lignin-degrading biological agents. Keywords: bacteria, ligninolytic, peroxidase

Abstract

Food safety is a science that deals with preparing, managing, and storing food or beverages to be safe from physical, biological, and chemical contamination. The processing of petis (condiments of fermented fish or shrimp) crackers is one of the categories of SMEs in Kendal Regency, Central Java. The study aimed to evaluate the heavy metals of iron (Fe), lead (Pb), and other chemical features and to survey the processing of petis crackers. This is a descriptive study of an observational nature with a quantitative approach, especially by doing laboratory observations. The study also carried out qualitative observations using questionnaires regarding the manufacturing of petis crackers. Petis is food or items cooked in a thick, clayey, and elastic condiment group. The results showed that Fe levels vary from 48.00 to 82.00 mg/kg and Pb from 40.00 to 50.00 mg/kg. The average chemical properties of the petis crackers are as follows: 2.45% ash, 13.27% moisture, 3.13% protein, 0.15% fat, and 81.0%carbohydrate. The lead content surpasses the maximum limit of the standard set by the BPOM (The Indonesian Food and Drug Supervisory Agency). Keywords: food safety, heavy metal, Kendal, petis crackers
