Abstract

The increasing of industrial activities and urbanization have led to the accumulation of heavy metals, which pose a high risk to human health and ecosystems. Adsorption using biochar from bamboo waste is an alternative solution as an adsorbent. This study evaluated the performance of biochar from pyrolysis of bamboo waste at various temperatures (300–600°C) for adsorption of lead (Pb²⁺) ions. The pyrolysis was conducted under a nitrogen gas atmosphere to prevent oxidation during thermal decomposition. Fourier Transform Infrared (FTIR) analysis revealed an increase in the stability of carbonyl (C=O) and carbon–nitrogen (C–N) functional groups with increasing temperature, which contributed to a stronger affinity for metal ions. Brunauer–Emmett–Teller (BET) analysis showed that biochar produced at 400 °C exhibited the most favorable surface characteristics, with a surface area of 178.56 m²/g, a pore volume of 0.091 cm³/g, and an average pore diameter of 2.05 nm. This sample also demonstrated the highest Pb²⁺ adsorption capacity of 52.4 mg/g. Despite higher porosity, the biochar produced at 600 °C showed diminished adsorption efficiency due to pore structure collapse and decreased carbon content. The findings suggest that biochar synthesized at 400 °C has strong potential for use in environmental remediation applications, particularly in mitigating lead contamination in water systems.

Abstract

A program that has not been implemented at the Demang Jaya Sehat Post of Occupational Health Effort is village-level meetings as an effort to provide solutions to problems obtained when conducting introspective surveys. Currently, cadres are not able to carry out socialization because they have never received training related to socialization media. This service aims to provide simple health socialization media training to UKK Demang Jaya Sehat Post Cadres as a motor in the farmer health program. This service begins with a pretest, then simple socialization media training consisting of concepts, sources, and practices, and ends with a posttest. All 7 cadres were active and enthusiastic in participating in the training held at the Demangan Village Hall as seen from several questions asked. Cadres carry out the practice of searching for information and data using Google with keyword accuracy indicators, as well as accessing the website promkes.kemkes.go.id to download socialization media in the form of videos, short films, posters, brochures, flyers, and leaflets. Cadres are considered proficient in using gadgets. The posttest results showed an increase in cadre understanding scores of 20.75% compared to before. This shows that training activities are effective in increasing the knowledge of Pos UKK cadres so that they are expected to be able to maintain the sustainability of the village safety farming program. The lowest score is in the aspect of validity and accuracy of information, so farmers still need assistance from the community health center and village government team in preparing and conducting counseling.

Abstract

Colocasia esculenta (taro) is a significant staple crop cultivated for its edible corms, roots, and leaves. Despite its agricultural importance, limited anatomical studies have focused on the vegetative organs (leaf, stem, and root) of various taro cultivars. This study aimed to describe and compare the anatomical structures of leaves, stems, and roots among six taro cultivars (Jepang putih, Jepang merah, Gambir, Semir, Ketan, and Sutra). The six cultivars were cultivated using sucker propagation in three replicated blocks. Parameters assessed included leaf, stem, root anatomy, chlorophyll content (a, b, and total), stomata characteristics, epidermal cell number and length, and root tissue thickness (epidermis, endodermis, cortex, and stele). Significant anatomical differences were found among the cultivars. The Gambir cultivar resulted in the highest chlorophyll a, b, and total chlorophyll content. Jepang merah had the thickest root epidermis and cortex, Gambir had the thickest endodermis, and Semir showed the thickest stele. Ketan cultivar had the highest number of stomata and epidermal cells. Anatomical variation exists among the six cultivars of Colocasia esculenta studied, indicating potential for cultivar-specific functional adaptations. These findings may contribute to cultivar selection and improvement for various agricultural and nutritional purposes.

Abstract

Bamboo plants in Indonesia are familiar plants and have not been utilized optimally. Most people only use the stems for daily needs and a small part for industry, while the leaves are left as waste. Bamboo leaves have a fairly high silica content. Bamboo leaves that have fallen and are scattered on the ground (bamboo leaf litter) are a potential source of natural silica. Silica fertilizer in agriculture is still very necessary, especially in nanosized. Through silica extraction from bamboo leaf litter, it is hoped that it will be able to meet agricultural silica needs and reduce bamboo leaf waste. The aim of this research is to modify the synthesis of silica from ori bamboo leaf litter (Bambusa blumeana) by extracting NaOH and KOH using the hydrothermal sol-gel method to produce nano silica. Nano silica production uses the hydrothermal method because it does not require large costs, is more effective, and has a high level of purity. Synthesis of original bamboo leaf litter silica using the hydrothermal sol-gel method. Bamboo leaf litter ash was analyzed using the XRF test, and silica was analyzed using the SEM-EDX mapping test to determine its morphology and content. The research results showed that synthesis with sodium produced higher levels of bamboo leaf silica compared to potassium. The size of the silica particles obtained is still in the form of micrometers (47–52 µm). Bamboo plants in Indonesia are familiar plants and have not been utilized optimally.

Abstract

Pesantren merupakan lembaga Pendidikan Islam di Indonesia yang memiliki peran dalam membentuk karakter dan keilmuan santri. Salah satu Pesantren Modern yang ada di Indonesia yaitu Pondok Modern Darussalam Gontor (PMDG) Putri Kampus 3 merupakan pengembangan dari PMDG Putri Kampus 1 yang berdiri untuk menampung jumlah santri yang meningkat. Kampus ini memiliki sistem Kulliyatul Mu’allimat Al-Islamiyyah (KMI) yang dibina dan dididik untuk menjadi wanita muslimah dan sholihah. Dalam upaya untuk mendukung pengembangan intelektual santri, PMDG Putri Kampus 3 menyediakan wadah kegiatan pengembangan seperti Exact Club dan praktek sains di kelas oleh pengajar. Namun, pemberdayaannya kurang optimal karena beberapa faktor, seperti keilmuan pengajar dan kegiatan yang kurang bervariasi. Oleh karena itu, program pengabdian masyarakat mengusung tema SDGs 4 yaitu pendidikan berkelanjutan. Kegiatan ini bertujuan meningkatkan kemampuan pengajar dan santri dalam bidang sains melalui praktik biologi, kimia, hidroponik, dan ecoprinting. Pengabdian dilaksanakan menggunakan  pendekatan sosialisasi, pelatihan, pembuatan modul, dan monitoring serta evaluasi.  Hasil kegiatan menunjukkan adanya peningkatan pengetahuan dan keterampilan peserta dalam penggunaan alat laboratorium serta pelaksanaan praktik ilmiah sederhana di lingkungan pesantren. Kegiatan ini diharapkan menjadi langkah awal dalam mengintegrasikan sains dan nilai-nilai Islam guna mendukung pendidikan yang berkelanjutan di PMDG Putri Kampus 3.    Kata kunci: Agroteknologi, pendidikan, pertanian, pesantren. ABSTRACT Islamic boarding schools are Islamic educational institutions in Indonesia that play a role in shaping the character and knowledge of students. One of the modern Islamic boarding schools in Indonesia, Pondok Modern Darussalam Gontor (PMDG) Putri Campus 3, is a development of PMDG Putri Campus 1, which was established to accommodate the increasing number of students. This campus has a Kulliyatul Mu’allimat Al-Islamiyyah (KMI) system that is fostered and educated to become Muslim women and pious. In an effort to support the intellectual development of students, PMDG Putri Campus 3 provides a forum for development activities such as Exact Club and science practices in class by teachers. However, the empowerment is less than optimal due to several factors, such as the knowledge of teachers, activities that are not varied enough. Therefore, this community service program carries the theme of SDGs 4, namely Sustainable Education, with an approach of socialization, training, module creation, and monitoring and evaluation. This activity aims to improve the abilities of teachers and students in the field of science through practices in biology, chemistry, hydroponics, and ecoprinting. The results of the activity show an increase in participants' knowledge and skills in the use of laboratory equipment and the implementation of simple scientific practices in the Islamic boarding school environment. This activity is expected to be the first step in integrating science and Islamic values to support sustainable education at PMDG Putri Campus 3. Keywords: Agriculture, agrotechnology, education, islamic boarding school.

Abstract

Background: It is required to provide adequate equipment to optimize farmers' pesticide safety management. Pesticide storage and rinsing facilities are necessary to improve farmers' pesticide safety management practices. Water, personal protective equipment (PPE), a pesticide box, and a first-aid box are all included. This study focuses on describing farmer behaviour in terms of pesticide storage and the use of rinse homes. Methods: Seven farmers from X Village's farmer group participated in this qualitative study. In-depth semi-structured interviews and observation were used to gather data. Interviews were taped and transcribed word by word, then categorized and coded. The data was interpreted, and the outcomes were examined accordingly. Results: The findings revealed that the farmers did not make effective use of the amenities. They simply used the water facilities for hand washing and tank rinsing, and they only wore masks instead of full PPE. The findings revealed that farmers are aware of the dangers of pesticides, but they are comfortable with their old practices and rely on the farmer's habits. The pesticide box increases storing behaviour significantly. Farmers have also made use of the first-aid kit. Conclusion: According to this research, the provision of facilities has not been able to modify farmers' behaviour in pesticide safety management. The first step towards changing one's behaviour is to become aware of the problem. The more intensive contact between planners, farmers, and other stakeholders are essential.
