Abstract

Bamboo can be used as a material in the manufacture of particleboard. The purpose of this study was to examine the effect of various types of bamboo and their adhesion on the physical and mechanical properties of particleboard. The study used a factorial completely randomized design with three repetitions. Particleboard made using cold pressing made of bamboo betung (Dendrocalamus asper Schult.), bamboo apus (Gigantochloa apus Kurz), bamboo ori (Bambusa arundinacea Retz), and Urea Formaldehyde and Polyvinyl Acetate adhesives. The particle size used was through eight meshes with an adhesive concentration of 20% and a target board density of 1 gram/cm³. Board testing using SNI 03-2105-2006, correlation analysis, and regression to see the relationship between variables. The resulting particleboard has a density between 0.5 – 0.69 gram/cm³, air content between 12.7% - 15.2%, thickness expansion between 2.2% - 17.55%, MOE 1.963 - 4.898 kg/ cm², MOR 4.89 – 9.36 kg/cm². The type of bamboo has no significant effect on density, moisture content, MOE, and MOR of particleboard. The type of adhesive has a significant effect on the density, MOE, and MOR of the particleboard. The interaction between the type of bamboo and the type of adhesive has a significant effect on the thickness development of the particleboard.

Abstract

Indonesia is an archipelago with more water than land, which is battling water and land pollution. One form of pollution is lead which is commonly caused by battery waste, fishing boat activities, diesel waste. One solution is phytoremediation using hyperaccumulator plants such as mangroves. Mangroves can absorb heavy metals and maintain ecosystem stability. The dominant species in Clungup Mangrove Conservation are Ceriops tagal and Rhizophora apiculata. The objectives of this study were: 1) To determine the level of lead metal (Pb) pollution in mangrove sediments in the area. 2) To determine the levels of lead metal (Pb) in the roots and leaves of mangrove species Ceriops tagal and Rhizophora apiculata. 3) To determine the ability of lead metal (Pb) absorption in mangrove plants Rhizophora apiculata and Ceriops tagal. Research activities began on February 20th - May 31th, 2023. The research was conducted at Clungup Mangrove Conservation in Sumbermanjing Wetan District, Malang Regency. Lab tests were conducted at the Unism Integrated Laboratory and Halal Center. Lead test results in sediments in this area are classified as very low. Lead levels in the roots of Ceriops tagal were higher than Rhizophora apiculata. Pb levels in the leaves of Ceriops tagal were also higher than the leaves of Rhizophora apiculata. Bioconcentration Factor (BCF) values were higher than Rhizophora apiculata, but both were categorized as lead removal plants (BCF < 1). The Transfer Factor (TF) value showed a lower value for Ceriops tagal than Rhizophora apiculata, indicating that Rhizophora apiculata has better translocation ability. However, both are categorized as unstable plants (TF < 1). The results of the phytoremediation calculations showed that Ceriops tagal had superior absorption potential compared to Rhizophora apiculata.

Abstract

Soil degradation is often indicated by reduced land productivity, which affects soil physical, chemical, and biological properties. The application of compost and biochar fertilizer serves as an alternative method for improving the physical and chemical properties of the soil. This study was conducted to determine the effect of applying compost and biochar to the soil on its physical and chemical properties. The research was conducted in Tambakrejo Village, Sumbermanjing Wetan, South Malang. The study employed a Randomized Complete Block Design (RCBD) with four treatments: control (P0), 15 kg of compost and 5 kg of biochar (P1B3), 10 kg of compost and 10 kg of biochar (P2B2), and 5 kg of compost and 15 kg of biochar (P3B1). The results indicated that the most effective application of compost and biochar in improving bulk density, soil temperature, Corganic, and available P content of the soil was the P3B1 treatment. The composition of compost and biochar P2B2 was found to increase soil pH. Additionally, the composition of P1B3 increased soil moisture, total N, and total K. Based on the results, the application of compost and biochar can reduce soil bulk density, improve soil temperature, pH, and moisture, as well as increase soil Corganic and NPK content.

Abstract

Abstrak Kegiatan yang sudah dilakukan pada tahun 2022 dalam program pengabdian internal tentang ternak lebah klanceng berhasil disosialisasikan kepada ibu-ibu PKK dan membentuk satu plot contoh yang berhasil dikembangkan. Masyarakat memiliki problematika dalam ternak yang baru dikenalkan serta belum memahami cara pemanenan hasil dari lebah, sehingga ini kegiatan berkelanjutan yang penting dilakukan untuk membentuk desa tretes yang mandiri nantinya. Metode sosialisasi kepada mitra ibu-ibu PKK sebanyak 27 orang program madu dilakukan untuk memberikan informasi penambahan. Selanjutnya praktek budidaya oleh ahlinya yang kami datangkan oleh pelaku budidaya lebah klanceng urban. Pembuatan atau desain produk lebah klanceng dari Pujon Hill. Program ternak lebah klanceng memiliki keunggulan yakni mudah dilakukan dan Kawasan hutan sebagai habitat yang cocok. Focus selanjutnya yang dilakukan adalah penambahan kapasitas yang nantinya bisa memberikan hasil panen yang cukup untuk bisa dijual dalam satu botol. Serta memberikan pelatihan proses panen madu klanceng pada botol. Ibu-ibu PKK mendapatkan skill cara pemanenan madu lebah klanceng. Hasil madu dari lebah klanceng yang didapat sekirat 10-15 ml, hasil ini tidak sebanyak lebah pada umumnya maka penggunaan botol mini yang khas bisa dilakukan untuk menarik konsumen dalam pemasaran produk nantinya. Kegiatan ini sudah terlaksana dengan baik. Terutama dalam penambahan koloni, saat ini terdapat 6 box kolodi yang dekat dengan hutan dan kemasan yang sederhana. Kata kunci: trigona; pujon hill; madu; masyarakat. Abstract Activities conducted in 2022 within the internal community service program on stingless beekeeping were successfully socialized to women in the Family Welfare Movement (PKK) and established a successful demonstration plot. The community faced challenges with this new breed and lacked understanding of how to harvest bees, making sustainable activities crucial for the future development of a self-sufficient Tretes village. Socialization was conducted with 27 PKK women partners in the honey program to provide additional information. Furthermore, cultivation practices were conducted by experts brought in from urban stingless beekeeping. The stingless bee product design and production were conducted from Pujon Hill. The stingless beekeeping program offers advantages such as ease of implementation and suitable forest habitat. The next focus is increasing capacity, which will eventually yield sufficient yields for sale in bottles. Training is also provided on the process of harvesting stingless bee honey in bottles. The PKK women gained skills in harvesting stingless bee honey. The honey yield from stingless bees is approximately 10-15 ml, which is not as high as that of other bees, so the use of distinctive mini bottles can be used to attract consumers in future product marketing. This activity has been carried out well. Especially in terms of colony expansion, currently there are 6 colloid boxes near the forest and simple packaging containing. Keywords: trigona; bukit pujon; honey; community.
