Abstract

Poor food safety in school children’s snacks (SCSS), characterized by the presence of hazardous additives like borax, formalin, and rhodamine B, poses significant risks to children's health, potentially leading to long-term health issues and developmental problems. This research aims to identify the presence of these dangerous substances in SCSS and determine which types of snacks pose the highest food safety risks. The study employed a simple random sampling method to collect popular snack samples frequently consumed by students in various areas of Jayapura. Qualitative testing for borax, formalin, and rhodamine B was carried out using test kits. The results revealed that several SCSS samples contained these harmful substances, with notable variability across different regions. The analysis identified specific types of snacks—such as meatballs, noodles, colorful beverages, and snacks—that failed to meet the expected food safety standards. The study concludes that hazardous food additives are still being used in the production and sale of SCSS in Jayapura City, posing significant health risks to children. Enhanced regulation and awareness initiatives are necessary to improve food safety in the region. Public health authorities are encouraged to implement stricter monitoring and provide targeted education to both vendors and consumers to reduce the prevalence of these unsafe practices. Key words: food safety; hazardous additives; Jayapura City; public health; school snacks.

Abstract

Organic waste, characterized by its high water content and rapid decomposition, poses environmental challenges and risks of disease outbreaks if not managed effectively. One promising solution is converting organic waste into compost. This study aims to quantify waste generation by weight and type while exploring composting as an alternative management strategy in Yuwanain Village, Arso District, Keerom Regency. The research employed methods including waste sampling, measurement, and data analysis, with the study area focused on Yuwanain Village. Over eight days, 255.25 kg of waste was collected, comprising 133.5 kg of organic waste and 116.75 kg of inorganic waste. Processing 133.5 kg of organic waste yielded approximately 20 kg of compost, representing 15% of the total organic waste weight. Overall, the conversion of organic waste into compost reduced waste generation by 53%. This composting potential offers a sustainable alternative for producing organic fertilizer, which could significantly contribute to agricultural systems in Keerom, Papua.

Abstract

Mangrove are one of the biotic components that form ecosystems in coastal areas. They are flowering plants with a tree habit that are highly tolerant of elevated salt levels. Mangrove ecosystems serve as habitats for various species of flora and fauna, and are therefore known for their high bioecological diversity. This study aims to analyze the bioecology of the mangrove ecosystem in Dasun Village, Lasem Sub-district, Rembang Regency, Central Java. The research method used was a survey with the transect line technique. Sampling of mangrove vegetation was conducted using square plots measuring 20 × 20 m, while fauna sampling was conducted within a 10-meter radius of the vegetation plots. All flora and fauna found within the plots were recorded as bioecological data of the mangrove ecosystem. Sampling was conducted in three different locations within the mangrove ecosystem area of Dasun Village. The results revealed three families of mangrove flora: Primulaceae (9 species), Combretaceae (5 species), and Rhizophoraceae (171 individuals). The mangrove fauna identified consisted of eight families from the class Gastropoda, two families from the class Malacostraca, and one family each from the classes Pisces, Aves, and Mammalia. Abiotic factors such as temperature, humidity, pH, and salinity were also measured. Temperature ranged from 29.3-33.8 °C, humidity from 68-73%, pH from 6.8-6.9, and salinity from 0.2-0.5 ppt. These results indicate that the mangrove ecosystem in Dasun Village supports a diverse range of mangrove flora and fauna, demonstrating its bioecological richness

Abstract

Soil macrofauna are important bioindicators of soil fertility. Soil fertility is strongly influenced by soil conditions, which affect the presence and density of macrofauna populations through the decomposition of organic matter. This study aimed to determine the diversity of soil macrofauna across different habitat types in the Batutegi Protection Forest (BPF), Tanggamus, Lampung. The methods used included pitfall traps, point counts, and hand sorting. Three plots were set up, each with three pitfall traps. The point count method involved walking a 100-meter transect with 10 stopping points, each observed for 10 minutes. The hand sorting method was conducted in three 25 × 25 cm plots at a depth of 20 cm. The soil macrofauna diversity indices obtained using the pitfall trap method were as follows: river border (H'=2.9), shrub area (H'=3.1), and forest interior (H'=3.1). Using the point count method, the diversity indices were: river border (H'=3.5), shrub area (H'=2.8), and forest interior (H'=3.3). The diversity indices from the hand sorting method were: river border (H'=2.7), shrub area (H'=2.4), and forest interior (H'=1.8).

Abstract

Arcangelisia flava (L.) Merr., commonly known as kayu kuning, is a medicinal plant traditionally used in Southeast Asian medicine. Various studies have identified bioactive compounds such as furanoditerpenes, alkaloids, flavonoids, tannins, and phenolic compounds that contribute to its pharmacological activities, including antimicrobial, antioxidant, and antidiabetic effects. Despite the growing body of research on its pharmacological potential, the mechanisms of action of these bioactive constituents remain inadequately understood, and clinical evidence supporting its use in modern therapy is still limited. This systematic review compiles data from diverse scientific sources, focusing on the phytochemical composition, extraction methods, pharmacological activities, and comparisons with conventional pharmaceutical agents. The analysis revealed that A. flava contains various bioactive constituents responsible for its therapeutic effects. Furanoditerpenes demonstrate antimicrobial and antifungal activity, while alkaloids and phenolic compounds exhibit significant antioxidant and antidiabetic properties. Extraction techniques varied across studies, affecting the efficiency of bioactive compound isolation. Comparisons with standard pharmaceuticals suggest that A. flava extracts exhibit comparable efficacy in several pharmacological domains. These findings indicate that A. flava holds considerable promise as a natural therapeutic agent. However, further investigations are needed to clarify its pharmacological mechanisms through pharmacokinetic and pharmacodynamic studies, as well as clinical trials to confirm its safety and effectiveness in human applications. The integration of modern technological approaches such as metabolomics and bioinformatics could facilitate the identification, standardization, and development of phytopharmaceutical products derived from A. flava, thereby advancing its potential use in evidence-based medicine.

Abstract

Kidney stones are a serious condition that often occurs in the wider community. The presence of this disease is influenced by genetic factors, diet, dehydration, irregular lifestyle, and unhealthy lifestyle. One of the treatments used to treat kidney stones is Percutaneous Nephrolithotomy (PCNL) for kidney stones measuring more than two centimeters. This study aims to find out about kidney stone treatment using the PCNL method. The method used is a literature study by discussing five study focuses, namely (1) healthy kidney structure and its role in maintaining body balance, (2) kidney structural abnormalities and their impact on health, (3) kidney stone treatment methods and their impact on health, (4) PCNL as a modern treatment solution for kidney stone sufferers, and (5) the process of implementing PCNL in kidney stone treatment. It can be concluded that healthy kidneys are vital organs with integrated structures and functions to maintain the physiological balance of the body and play a role in producing the hormones renin, erythropoietin, and calcitriol. Kidney disorders that often appear are kidney stones caused by waste in the blood or crystallized chemicals such as calcium and oxalic acid. Pharmacological therapy is a therapy that is often used to treat kidney stones using medical drugs and also surgery, but this method has side effects due to the drugs given. PCNL is a non-invasive treatment that utilizes sophisticated medical technology to treat kidney stones. PCNL treatment is done by making a small incision in the skin of kidney stone sufferers so that it does not have significant side effects. PCNL has a high success rate for the treatment of kidney stones

Abstract

This study investigates Bungkus leaf (Smilax rotundifolia), a well-known plant in Papua commonly referred to as the three-finger leaf. Indigenous Papuans traditionally use this plant to enlarge genitals, buttocks, and breasts, as well as to treat syphilis. The plant is known to contain flavonoid and phenolic compounds with pharmacological activity. This study aimed to determine the total flavonoid and total phenolic content of the 70% ethanol extract of Bungkus leaf. The research began with simplicia preparation, followed by extraction using 70% ethanol. Qualitative tests, including phytochemical screening and thin-layer chromatography (TLC), were conducted, followed by quantitative analysis using UV-Vis spectrophotometry. The results showed total flavonoid content of 54.696 mg QE/g ± 0.565 and total phenolic content of 32.908 mg GAE/g ± 0.263. The study concluded that the total flavonoid content was higher than the total phenolic content. Toxicity testing categorized the extract as toxic, with an LC50 value of 442.92 ppm.

Abstract

Gold mining boosts Indonesia's GDP and exports. However, gold mining changes soil chemical and biological qualities, and therefore harming the environment. Thus, rehabilitating post mining land using environmentally friendly and chap method are essential for soil and ecosystem health. Nitrogen (N), and phosphorus (P) are the most limiting factors in degraded mining area. Azotobacter sp. and Rhizobium sp. are well-known in assisting plant by providing N. Paraserianthes falcataria is well-known as a fast-growing tree species that have good symbiosis with Rhizobium sp. This study examines the chemical and biological effects of underground gold mining on soil and the ability of indigenous Azotobacter sp. and Rhizobium sp., to improve the soil of post gold mining under greenhouse condition. Soils were sampled from natural forest (NF), tailing (T), and 3 different ages of rehabilitated area: 1 year old, 2 year old, and 5 year old. According to this study, gold mining negatively effect on soil organic carbon and nitrogen levels. One Rhizobium sp. isolate and 12 Azotobacter spp. isolates were found in post mining soil. All Azotobacter spp. isolates fixed nitrogen by NFB test and produced IAA. All Azotobacter spp. was determined as gram negative bacteria. A greenhouse study found that Azotobacter sp. inoculation with 10% compost improved the soil quality by increasing soil organic carbon, soil N, soil available P, and exchangeable K. Therefore, this improvement on soil condition increased seedlings height, diameter, and biomass growing in gold tailings soil. These findings highlight the necessity of employing indigenous microorganisms and organic materials to improve soil quality and plant growth on former gold mining areas.

Abstract

This study aims to explore and test the quality of Trichoderma spp. local from the rhizosphere of apus bamboo (Gigantochloa apus) against Fusarium spp. wilt disease both in vitro and in vivo in tomato. This research was conducted in the Keerom area, Jayapura, which is one of the centers of food crop production and horticulture in Papua. The data obtained from this study were analyzed by comparing the inhibition of three Trichoderma spp. isolates (Trichoderma sp. 1 isolate, Trichoderma sp. 2 isolate, and Trichoderma sp.3 isolate) against Fusarium spp. The results of the antagonist test showed that the isolate of Trichoderma sp.3 had the highest inhibition (80.56%) against Fusarium spp., followed by Trichoderma sp.2 (66.84%) and Trichoderma sp.1 (27,62%). The implication of this study is that Trichoderma sp. 3 has high potential as an APH in the control of Fusarium spp. wilt disease in tomato plants. The use of Trichoderma spp.-based APH can be an effective and environmentally friendly alternative in reducing the use of chemical pesticides and maintaining the balance of the agro-environmental ecosystem.
