Abstract

Diarrhea and typhoid fever are diseases commonly suffered by people in Indonesia, and bacteria such as Escherichia coli (diarrhea) and Salmonella typhi (typhoid fever) are one of those diseases causative agents. Various plants are potentially used as anti-bacterial including ulin (Eusideroxylon zwageri). The aims of this study were to analysis the yield and potential secondary metabolite content in ethanol extract of E. zwageri, and determine the optimal concentration in inhibits the growth of bacteria E. coli and S. typhi. The methods used in this study were measure the moisture content of E. zwageri wood bark powder, extraction with ethanol solvent, measure the yield percentage, qualitative of phytochemical analysis, and antibacterial assays. The results showed that the yield of ethanol extract of E. zwageri is 21,63% with 7,6% of moisture content. The extract positively contained alkaloids, flavonoids, tannins, saponins, phenolics and terpenoids. The optimum concentration in inhibits the growth of bacteria E. coli is 200 mg/ml and categorized as very strong inhibition response, and 15 mg/ml is concentration used in inhibits the S. typhi and categorized as strong inhibition response.Keywords: Antibacterial activity, Escherichia coli, Eusideroxylon zwageri, phytochemical screening, Salmonella typhi.

Abstract

This research aim was to know the chemical distribution of wood (Macaranga hosei King) based on its stem height/axial direction (base, middle and end of stem) and the depth of stem/radial direction (2/3 3/3 rays, 1/3 2/3 rays and 0 1/3 rays). The experimental includes the percentage of alcohol benzene-soluble extractive content, lignin content, holocellulose and ?- cellulose. The result showed base on stem height that the percentage of alcohol benzene soluble extractive, lignin, holocellulose and ?- cellulose content decrease from the base, middle and to the end of stem. Base on depth of stem, the result showed that the percentage of alkohol benzena-soluble extractive content, lignin content, holocellulose and ?- cellulose decreasing from 2/3 3/3 rays, 1/3 2/3 rays and to the part of 0 1/3 rays. The interaction of stem height and depth of stem has significantly affected to the percentage of alcohol benzene-soluble extractive content. The overall result showed that Mahang wood is suitable for used as sawn timbers, wood panels and raw materials for pulp and paper. Keywords: chemical properties, Macarang hosei, stem height, stem depth.

Abstract

The Dayak tribe has a close relationship with nature. They are used to using natural resources such as plants for various needs, including as an ingredient in traditional medication. The Dayak Belangin, one of the Kanayatn Dayak sub-tribes in Dange Aji Village, Landak District, is still using medicinal plants to treat illnesses in their community. This research was conducted to document the knowledge of the dayak Belangin people in Dange Aji Village in utilizing plants as traditional medicine. A total of 163 households of the dayak Belangin community in Dange Aji Village were selected by purposive sampling and in-depth interviews to obtain information about the community's knowledge of using plants as medicine. The data obtained were then analyzed using ethnobotanical indices such as use value (UV), family importance value (FIV), informant consensus factor (ICF), and fidelity level (FL). All respondents interviewed used medicinal plants, with in total there are 53 species belonging to 34 plant families. Asteraceae is a plant family with the highest FIV (11.76). Jambu tokal or guava (P. guajava), mabo (Blumea balsamifera), and engkodok (Melastoma candidum) had the highest UV values (0.76; 0.71, and 0.71, respectively). The highest ICF score (1) includes cancer, wounds, urinary stones, rheumatism, gout, allergies, malaria, hypertension, bloody bowel movements, colds, sore eyes, colds, cholesterol, and broken bones. There are 43 plants with the highest FL value (100%). The local knowledge of the dayak Belangin tribe is prized and must be maintained, especially for the benefit of science and the development of new modern medicines.

Abstract

Utilizing plants that grow around your home is an effective way to meet food needs and is a concrete manifestation of food independence. This research aims to analyze the pattern of the use of plants as a food source by the people of Raut Muara Village to achieve food independence. The study was carried out by conducting interviews with selected respondents. Respondents were selected using the purposive sampling method. A total of 108 selected respondents were successfully interviewed. The people of Raut Muara Village use 104 types of plants as food. These plants are used as vegetables, fruit, grains, sources of carbohydrates, spices, drinks, and traditional medicines. Plants that have the highest use value (UV) are pilo leaves or cassava leaves (Manihot esculenta) and rice (Zea mays) with the highest UV value (1). All categories of food plant utilization found in the Raut Muara Village community were classified as high (0.94-0.98). The highest FL value (100%) was found in almost all utilization categories except the category of utilization as traditional medicine. The people of Raut Muara Village have extensive experience in utilizing the surrounding environment to cultivate several types of food plants, especially plants that produce fruit, vegetables, and sources of carbohydrates. This is an effort to achieve food independence.Keywords: Community, edible plants, food security, utilization, Raut Muara village, AbstrakPemanfaatan tumbuhan yang tumbuh disekitar tempat tinggal merupakan cara yang efektif untuk memenuhi kebutuhan pangan dan sebagai wujud nyata dalam kemandiran pangan.

Abstract

Jeruk purut (Citrus hystrix) memiliki potensi untuk dikembangkan sebagai tanaman agroforestri karena sebagai tanaman penghasil minyak atsiri dan dapat digunakan sebagai bahan obat, salah satunya sebagai antibakteri. Komponen kimia minyak atsiri yang terkandung dalam suatu tanaman sangat bergantung pada tempat tumbuhnya dan hal tersebut tentu akan menentukan tingkat aktivitasnya sebagai antibakteri. Tujuan penelitian yaitu mengidentifikasi komponen kimia minyak atsiri daun jeruk purut yang berasal dari Kalimantan Barat dan bioaktivitasnya dalam penghambatan pertumbuhan bakteri Salmonella typhi dan Salmonella Typhimurium. Daun jeruk purut dilakukan penyulingan dengan metode uap dan minyak atsiri yang dihasilkan diidentifikasi komponen kimianya menggunakan GC MS (Gas chromatography–mass spectrometry). Pengujian bioaktivitasnya terhadap bakteri S. typhi dan S. typhimurium menggunakan empat taraf konsentrasi yaitu 0,5; 1; 5 dan 10%. Sebanyak 12 senyawa teridentifikasi dalam minyak atsiri daun jeruk purut dengan 5 senyawa utamanya adalah sitronellal (80,83%), 2,6-oktadiene (5,36%), bicyclo (3.1.0) hexane (3,79%), sitronellol (3,48%) dan linalol (2,57%). Pertumbuhan bakteri S. typhi atau S. Typhimurium dapat terhambat oleh minyak daun jeruk purut dan penghambatannya pada konsentrasi 10% tergolong lemah yaitu sebesar 1,17 mm dan 1,42 mm.

Abstract

PT XY Kabupaten Mempawah merupakan industri pengolahan hasil hutan kayu yang bergerak pada bidang industri penggergajian (sawmill) yang produk lanjutannya dimanfaatkan sebagai produk moulding berupa stik dupa. Permasalahan yang sering terjadi pada proses produksi stik dupa yaitu masih sering ditemukan produk stik dupa yang mengalami kecacatan. Penelitian ini bertujuan untuk menganalisis proses pengendalian kualitas produk serta penyebab kecacatan pada proses produksi stik dupa. Pada penelitian ini metode analisis yang digunakan yaitu Statistical Quality Control (SQC) berupa check sheet, diagram pareto, diagram kendali, diagram alir, dan fishbone chart. Hasil dari penelitian ini menunjukkan bahwa kualitas produk stik dupa masih belum terkendali. Ditemukan 4 jenis cacat produk yang sering terjadi seperti cacat bengkok, cacat bentuk tidak sesuai, cacat berlubang dan cacat patah. Cacat yang paling dominan terjadi yaitu cacat bengkok yang berjumlah 37.919 batang dengan presentase 58,19% dari total produk cacat yang diproduksi di bulan Mei 2023. Berdasarkan hasil observasi lapangan dan wawancara serta analisis fishbone chart menunjukkan bahwa unsur-unsur penyebab terjadinya produk stik dupa cacat yaitu bahan baku, mesin, manusia, lingkungan kerja, dan cara kerja.
