Abstract

Fast growing jabon is largely rotary-cut to produce veneer for plywood, com-ply, and LVL. In order to provide better information on veneer production and utilization, in this study the effects of wood juvenility and veneer thickness on lathe checks of jabon rotary-cut veneer were evaluated. Before veneer manufacturing, the jabon log was boiled at 50 and 75 °C for 4 and 8 hours respectively. The boiled logs were peeled to produce veneer of 1 and 2 mm thick. Lathe checks of veneers were measured under an optical video microscope. The rotary-cut veneer was grouped and evaluated separately at every segmented ring of 1 cm from pith to bark. The results showed that wood juvenility and veneer thickness had an important effect on lathe checks for the rotary-cut veneer. In general, the number of lathe check of the veneer increases with increasing veneer thickness and increase from pith to bark. Boiling of logs before rotary-cutting could decrease the value of lathe check. The results indicated that boiling of logs at 50 °C for 8 hours, and at 75 °C for 4 and 8 hours could minimize the number of lathe checks in manufacturing of 1 and 2 mm rotary-cut veneer from juvenile wood jabon.

Abstract

Pooti (Hopea gregaria) is an endemic plant in Southeast Sulawesi that produces resin. But until now it has not been used because information about the quality of pooti resin has never been available. Therefore, this study aims to test the quality of pooti resin based on visual, acid number and ash content test. Pooti sap taken is on a tree with a diameter of 30 cm and a visual test is carried out based on SNI 2900-1-2012 and SNI 2900.2: 2013 for laboratory tests. The result is pooti resin with a clear yellowish color with a chunk size> 3x3 cm2, based on SNI 2900-1-2012 classified as Quality Class A. While the ash content value is 0.7% and the acid number is 29. This value indicates the ash content and acid number based on Laboratory tests are classified as quality class II based on SNI 2900.2: 2013.

Abstract

Fast growing sengon is largely rotary-cut to produce veneer for plywood, com-ply and LVL. In order to provide better information on veneer production and utilization, in this study the effects of wood juvenility and veneer thickness on lathe checks of sengon rotary-cut veneer were evaluated. Before veneer manufacturing, the sengon log was boiled at 50 and 75 oC for 4 and 8 h, respectively. The boiled logs were peeled to produce veneer of 1 and 2 mm in thickness. Lathe checks of veneers were measured under an optical video microscope. The rotary-cut veneer was grouped and evaluated separately at every segmented ring of 2 cm from pith to bark. The results showed that wood juvenility and veneer thickness had an important effect on lathe checks for the rotary-cut veneer. In general, the number of lathe check of the veneer increases with increasing veneer thickness and increase from pith to bark. Boiling of logs before rotary-cutting could decrease the value of lathe check. The results indicated that boiling of logs at 50 oC for 8 h, and at 75 oC for 4 and 8 h could minimize the number of lathe checks in manufacturing of 1 and 2 mm rotary-cut veneer from juvenile wood sengon.Key words: juvenility, lathe check, Paraserianthes falcataria, rotary-cut veneer, veneer thickness

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan pengetahuan dan keterampilan petani dalam penyediaan bibit MPTS (Multy Purpose Tree Species) yang berkualitas, melalui pemberian materi dan demonstrasi pembuatan media tanam yang tepat. Materi yang disampaikan oleh Dr. Basruddin, SP., M.Si., dan Dr. Ir. Yenni Widyana Nurchahyani Ratnaningrum, S.Hut., M.Sc., mencakup pentingnya media tanam yang optimal, seperti komposisi pasir, tanah, dan kompos, serta peran petani dalam memastikan bibit yang sehat dan bebas penyakit. Demonstrasi ini melibatkan penyusunan campuran media tanam yang tepat, serta pemindahan bibit ke dalam kantong polibag. Teknik-teknik yang disampaikan bertujuan untuk mendukung pertumbuhan bibit yang kuat dan sehat, yang nantinya dapat ditanam di lokasi rehabilitasi. Dengan pengetahuan yang diperoleh, petani diharapkan dapat meningkatkan kualitas bibit dan mendukung keberhasilan program rehabilitasi serta pemulihan ekosistem secara berkelanjutan. Kegiatan ini memberikan keterampilan praktis yang sangat dibutuhkan dalam usaha menghasilkan bibit berkualitas untuk tujuan rehabilitasi lahan dan konservasi alam.

Abstract

The objective of this community service activity was to improve the understanding of fifth-grade students at SD 92 Kendari regarding the medicinal plant Melaleuca cajuputi through an ecotourism education programme at the Halu Oleo University Botanical Garden. The methods used included presenting material on the benefits of medicinal plants, particularly cajuput, as well as direct observation of cajuput trees in the botanical garden. The activity also involved explanations from the botanical garden managers regarding biodiversity and the importance of preserving medicinal plants. The results of this activity showed a significant increase in students' knowledge of the medical and ecological benefits of cajuput. Before the activity, most students only knew white wood as a mild medicinal product, but after participating in the activity, 85% of students demonstrated a deeper understanding of the medical benefits of white wood, including its antimicrobial, anti-inflammatory, and analgesic properties. Additionally, students developed an awareness of the importance of preserving medicinal plants and biodiversity. This eco-tourism-based educational activity proved effective in increasing students' interest in environmental conservation and introducing them to sustainability concepts. These findings underscore the importance of developing botanical gardens as educational centres that can support environmental conservation and the preservation of medicinal plants for a better future.

Abstract

Water is an essential element for human life; without water, humans will experience a lack of fluid, the fluid in the human body is around 50-80. Water can fulfill daily needs through human activities such as washing clothes, water for drinking, bathing, and so on. Well, water is suitable for use if it meets water quality standards. This type of research uses descriptive research methods. This research is located in Baruga Market, Anduonohu Market, Lorong Salangga, and Kendari Permai Kendari City in December 2023. the samples used in this study amounted to 4 wells. The results obtained in this study are that all well water is polluted with E. coli, and Baruga Market well water exceeds the quality standards for Coliform parameters.  The presence of E. coli in all well water samples indicates fecal contamination, posing severe health risks such as waterborne diseases. Baruga Market's well water exceeds Coliform standards, likely due to sewage runoff, making it unsafe without treatment. Immediate actions, like improving sanitation and providing clean water alternatives, are necessary to prevent further contamination and protect public health.
