Abstract

The broiler chicken farming industry in Indonesia continues to experience rapid growth in line with the increasing demand for chicken meat. To support the development of this industry, one of the main challenges that must be addressed is the availability, efficiency, and quality of feed. The aim of this study was to determine the effect of Black Soldier Fly (Hermetia illucens) maggot oil as a feed additive on the performance, abdominal fat, and intestinal E. coli of broiler chickens. This research was conducted experimentally using a completely randomized design (CRD) with 5 treatments and 4 replications. Each experimental unit consisted of 5 MB-212 P broiler chickens from PT. Japfa, with the following treatment details: R0 – 0% maggot oil in the feed; R1 – 0.5% maggot oil (14-day-old) in the feed; R2 – 1% maggot oil (14-day-old) in the feed; R3 – 0.5% maggot oil (28-day-old) in the feed; and R4 – 1% maggot oil (28-day-old) in the feed. Results of the Duncan’s Multiple Range Test showed that all measured parameters, except for abdominal fat, were significantly affected (P<0.05) by the supplementation of maggot oil in the feed. The addition of 1% maggot oil from 14-day-old larvae as a feed additive significantly improved broiler performance, as indicated by the highest feed intake of 352.28 g/bird, live weight of 1,058.5 g, carcass percentage of 83.44%, abdominal fat of 1.47%, and intestinal E. coli count of 4.00 × 10⁵ CFU/g.However, the supplementation of 1% maggot oil from 28-day-old larvae resulted in poorer broiler performance, as indicated by lower feed intake (286.90 g/bird) and a relatively high feed conversion ratio (FCR) of 2.03.

Abstract

The surrounding environment is one of the primary factors influencing children's behavior. The environment has the potential to exert both positive and negative influences. This study aims to explore the impact of the surrounding environment on the behavior of elementary school students. The research employs a qualitative descriptive approach, with data collected through observation and interviews. Field findings indicate that negative environmental influences can lead to undesirable behaviors among students, such as the tendency to use inappropriate language in communication. This study is expected to be followed up with the implementation of the "Goodness Advice Program" (NABA), which focuses on habituating students to consistently exhibit positive behavior. For more severe issues, schools are encouraged to collaborate with parents and the community to provide appropriate parenting support.

Abstract

The swampy waters of Danau Bangkau, South Kalimantan are swampy waters that have an economic impact on the surrounding community. There is a need for research to know the productivity status of these waters from the abundance and diversity of fish. The research was carried out by dividing into 3 fish sampling stations determined by purposive sampling. The fish samples obtained were identified from families and species. The parameters observed and analyzed included the relative abundance of fish, diversity index, Evenness index, and Dominance Index. The results of the study were obtained from 1,108 individual fish and 28 species from 10 families. The results of the study show that the largest relative abundance is from the Cyprinidae family, which is 56.14% and this indicates that the waters are quite healthy because many fish are inhabited by herbivorous eating properties. The Diversity Index (H') obtained was 2.53 – 2.71, Evenness Index 0.52 – 0.55 and Dominance Index 0.37 – 0.44 which means that the waters are still healthy, with moderate productivity, but tend to be somewhat disturbed. The implication is that in the future there must be protection of the swampy waters of Danau Bangkau with strategies to restrict fishing and control sedimentation and domestic pollution.

Abstract

This article analyzes the factors that influence the food security of lowland rice farmers' households in tidal land, Barito Kuala Regency. Respondents from this study were 100 rice farmers in tidal land. The analysis for consumption patterns and food security uses descriptive analysis with an approach to the level of adequacy of energy and protein, while for the analysis of factors that affect food security uses a binary logistic regression model. The results showed that the pattern of energy consumption by rice farmers in tidal swamp land was 1,668 calories/capita/day and protein was 48.37 grams/capita/day. The number of farmers who are included in the food security category is 62.00% and 38.00% are not food secure. Households with high food income, small proportion of food expenditure, large availability of food and large area of rice farming land have the opportunity to be more food secure than farmer households on the other hand.

Abstract

The composites of biopolymer chitosan obtained from the swamp fish scale with bentonite as clay minerals has been characterized by the structural, mechanical, surface functional group and composition properties using scanning electron microscopy (SEM), thermal gravimetric analysis (TGA), X-ray fluorescence (XRF) and X-ray Diffraction (XRD) analysis. The morphology structure obtained by SEM for the original chitosan, bentonite, and its composites showed that the particles are relatively well dispersed in the chitosan matrix. The physicochemical properties of the chitosan-bentonite composites depend significantly on the chemistry of the polymer matrices, the nature of bentonite, their modification, and the preparation methods that showed by SEM, TGA, XRF and XRD analysis. The obtained composite of chitosan bentonite was then applied for treating raw water sources of drinking water in Bilu river, South Kalimantan, during the dry season. The raw water sources contained a high value of turbidity (ca. of 370±30 NTU) and color (1300±150 Pt-Co). Batch experiment using the composite of chitosan bentonite for treating raw water sources was significant to reduce the value of turbidity, and the color becomes 24.8±2 NTU and 86.7±5 Pt-Co, respectively. The results then compare to the treatment using the commercial chitosan and bentonite self. Moreover, it found that the raw water treatment using the composite of chitosan-bentonite is more favorable than chitosan and bentonite materials.

Abstract

Botanical pesticides are supporting sustainable agricultural systems with a focus on the efficiency of pest control and reducing the negative effect of synthetic pesticides. Many plant species such as neem, soursop, and jatropha were found to have the potential to control pests, including whitefly (Bemisia tabaci). B. tabaci is an important pest in cayenne pepper cultivation. This study aims to find botanical pesticides effectiveness against B. tabaci on cayenne pepper growth in peatlands. This study used a one-factor randomized group design method. The factor studied was a pesticide solution (p), p0 as a control we used Abamectin, and 3 types botanical pesticides, p1 = soursop leaf, p2 = neem leaf, and p3 = jatropha leaf, each treatment is repeated 6 times. The results showed that the application of botanical pesticide solution had an effect on mortality and intensity of pest attack. The best treatment in the study was neem leaf pesticide (p2) which caused whitefly mortality of 96.7% and reduce pest attacks intensity to 5,10%.

Abstract

Swamp buffalo on Kalimantan island is reared under an extensive production system. Minimum farmer input and decreasing swamp grass availability during the wet season lead to lower buffalo morphometrics, lower reproductive performances, and a higher calf mortality rate. This participatory study was conducted to evaluate the calf's performance after receiving a concentrate feed formulated using water mimosa (Neptunia oleracea) leaf meal as a protein source. Results of the study showed that water mimosa leaf meal has high crude protein content (>30%). After 4 months of observation, feeding concentrate feed formulated with water mimosa leaf meal as a protein source improved the growth of swamp buffalo calves. The calves in concentrate feed group showed body weight gain of 14.84 kg/month, growths of chest girth 13.6 cm, and height at wither 5.6 cm those improved compared to those in the group that did not offer concentrate feed that had the growths in chest girth 9.2 cm and height at wither 5.2 cm. This study provides valuable insights into the potential of using water mimosa leaf meals as a protein source for concentrate feed, which can enhance the growth of buffalo calves while resolving the issue of water mimosa invasion in the swamp area.

Abstract

Coliform bacteria contamination in wetlands poses a risk of causing waterborne diseases. Disinfectants are bactericidal, effectively reducing bacterial colonization in water. The coastal plant of mangrove nyirih or Xylocarpus granatum (X.granatum) contains various antibacterial compounds, so it can be used as a natural disinfectant. This study aims to analyze the bacteriological ability of mangrove nyirih as a disinfectant in water samples contaminated with Coliform. This laboratory experimental study used a pretest-posttest control group design. The dilution method was used to observe the effects of 25%, 50%, 75%, and 100% ethanol extract of mangrove leaves (L) and bark (B) of X.granatum as well as chlorine control. The parameters observed were the Coliform Most Probable Number (MPN) and Total Plate Count (TPC) in the test water sample. The results of the study, obtained a decrease in the Coliform MPN and TPC numbers of water samples after treatment. LB100% X.granatum extract produces an effect that is not significantly different from chlorine. In conclusion, mangrove nyirih has the ability as a water disinfectant.
