Abstract

Marsidudu is a traditional steam bath tradition performed by the Mandailing Batak sub-ethnic group. This research was conducted to determine the knowlodge of the Mandailing Batak ethnic community about the marsidudu tradition. Data collection was carried out through in dept interview. The results of the study show that the Mandailing Batak ethnic community utilizes 29 types of plants used for the marsidudu tradition. The perceived benefits of marsidudu are refreshing the body, relieving muscle pain, relieving stress, relieving aches, improving blood circulation and the body feeling more fragrant and having bright vision. In the process of carrying out this marsidudu there are 3 stages, namely boiling the ingredients, carrying out marsidudu and after doing marsidudu. The results of quantitative data analysis showed that Nypa fructicans was the type of plant that had the highest ICS value of 600. The part of the plant that was most used for marsidudu was the leaves (52,7%).

Abstract

Hamparan Rawang District is one of the sub-districts in Sungai Penuh City, Jambi Province which has a culture and tradition. One of the traditional ceremonies in Hamparan Rawang District is the Kenduri Sko Traditional Ceremony or what is called Kenduri Pusako. Assessment of the cultural importance of plant species diversity in Kenduri Sko is useful in ethnobotanical studies which include subsistence activity strategies and traditional classifications. Data collection was carried out by interviewing key informants using the "in depth interview" method, then estimating the cultural importance value of each plant species used in Kenduri Sko with the ICS(Index Cultural Significance) formula. The results of the study found that Kenduri Sko is a tradition that symbolises the greatness of customs in their respective regions with the aim of improving friendship and which is characterised by the crowning of traditional titles, cleaning heirlooms and uniting male children of butino children. Based on the results of interviews and estimation of ICS values, it is known that the ICS value of useful plants for Kenduri Sko ranges from 8 to 50. Areca nut (Areca catechu L ) has the highest ICS value, while Cynodon dactylon (L.) Pers. has the lowest ICS value.

Abstract

An experiment on the effect of elicitor concentrations derived from Pythium aphanidermatum (Edson) Fitzp on ajmalicine content of Catharanthus roseus (L.) G. Don Cell aggregates culture has been conducted. The following concentrations of elicitor tested were 0.05; 0.5; 1.0 and 5.0 mg DW/mL. The harvesting times were 0; 18; 36 and 72 hours after elicitation. The ajmalicine was analyzed qualitatively and quantitavely by using High Performance Liquid Chromatography (HPLC). Ajmalicine content was influenced by the concentration of elicitor and harvesting time. The highest content of ajmalicine in the cell aggregates (13.089 ± 0.086 µg/gDW) was achieved by addition 1.0 mg DW/mL of elicitor after 18 hours whilts in the medium  (346.728 ± 2.843 µg/gDW) was achieved by addition 1.0 mg DW/mL of elicitor after 36 hours   Kata kunci: Catharanthus roseus (L.)

Abstract

This research was conducted  to reveal the effect of the Gibberellins concentration  (GA3) on the content of crude protein (CP), acid detergent fiber (ADF) and neutral detergent fiber (NDF) of Calopogonium caeruleum. The design of experiment was the Completely Randomized Design (CRD) in factorial arrangement. The first factors were the concentrations of GA3 namely 0, 100, 200, 300, 400 and 500 ppm, for G0,G1, G2, G3, G4, and G5 respectively and the second factors were the soaking time at 6, 12 and 24 h, for T1, T2 and T3 respectively. Each treatment has three replications. The results showed that there were not significant (P< 0.05) effect of the concentration of GA3 on the content of CP, ADF and NDF of Calopogonium caeruleum.

Abstract

The aims of this study was to reveal the effectiveness of the use of Probio_FMplus broiler. Two hundret of day old chick (DOC) were used in this experiment. DOCs were randomly treated into five treatments with five replications consiting of eight DOCs. Treatments were the use of Probio_FMplus within drinking water of 0, 10, 15 and 20 ml/liter for treatment P0, P1, P2, P3and P4 respectively. The design of experiment was Completely Randomized Design with five treatments and five replications. Parametters measured were ration comsumption, weight gain, slaughter weight and feed conversion. The results of this experiment showed that the level of Probio_FMplus in drinking water did not significantly influence (P>0,05) on ration consumption, weight gain, slaughter weight and feed conversion. It could be concluded that the use of 10 ml/liter of Probio_FMplus in dringking waterwas the most effective in broiler. Kata kunci: probiotik, prebiotik, simbiotik, putak

Abstract

The traditional boat making by the Batanghari community in Jambi is a cultural heritage containing ethnoscience values. This local knowledge encompasses several aspects, including physics, biology, and technology, which can be integrated into science education in schools. This article discusses the potential of ethnoscience in traditional Batanghari boat making and its implementation in science learning based on local wisdom. The aim of this research is to explore and analyze the local wisdom of the community along the Batanghari River as a natural science learning resource. This study is a qualitative descriptive research. The subjects of this research are boat-making experts and community leaders, with the research object covering the area along the Batanghari River. The technique used is snowball sampling with instruments including observation sheets, interview sheets, and documentation. The data analysis technique applied is the Miles and Huberman model (data reduction, data display, and conclusion drawing/verification). The results of this research show that the local wisdom of the communities along the Batanghari River has a significant potential to be used as a science learning resource. This local wisdom has been formed over generations, influencing the daily cultural patterns and community activities, which can effectively bridge indigenous knowledge with formal science concepts in school.

Abstract

Tandan buah kosong (EFB) kelapa sawit merupakan limbah lignoselulosa yang berpotensi sebagai bahan baku bioetanol; namun, hidrolisatnya miskin nutrisi (N, P, K), yang menghambat pertumbuhan dan aktivitas fermentasi Saccharomyces cerevisiae. Penelitian ini bertujuan untuk menentukan pengaruh pupuk NPK dan KCl terhadap pertumbuhan S. cerevisiae, mengidentifikasi perbedaan signifikan antara kedua sumber nutrisi tersebut terhadap kandungan bioetanol, dan menentukan rasio nutrisi NPK-terhadap-KCl yang optimal untuk produksi bioetanol dari EFB. Penelitian ini menggunakan Rancangan Acak Lengkap (CRD) dengan enam perlakuan: kontrol (P0) dan rasio KCl:NPK 4:0 (P1), 3:1 (P2), 2:2 (P3), 1:3 (P4), dan 0:4 (P5), masing-masing dengan empat ulangan. Fermentasi dilakukan selama 7 hari pada pH 4 dan suhu ruangan. Pertumbuhan ragi diukur menggunakan OD600, sedangkan kandungan bioetanol diukur menggunakan refraktometer. Data dianalisis menggunakan ANOVA Satu Arah diikuti dengan uji HSD Tukey pada tingkat kepercayaan 95%. Hasil menunjukkan bahwa nilai OD meningkat pada semua perlakuan, dengan nilai tertinggi pada rasio 2:2 (0,789) dan terendah pada kontrol (0,331). ANOVA menunjukkan bahwa variasi rasio KCl terhadap NPK memiliki pengaruh yang sangat signifikan terhadap kandungan bioetanol (F(5,18) = 41,830; p < 0,001). Uji HSD Tukey mengelompokkan perlakuan menjadi tiga subkelompok: kontrol (11,6%) berbeda secara signifikan dari semua perlakuan yang diberi suplemen nutrisi; rasio 4:0 (13,3%) membentuk subkelompok terpisah; Sementara rasio 0:4, 3:1, 1:3, dan 2:2 (14,4–15,3%) tidak berbeda secara signifikan satu sama lain tetapi berbeda secara signifikan dari kontrol dan rasio 4:0. Kandungan bioetanol tertinggi diperoleh pada rasio 2:2 (15,3%). Disimpulkan bahwa nutrisi KCl dan NPK memengaruhi pertumbuhan S. cerevisiae dan menghasilkan perbedaan signifikan dalam kandungan bioetanol dari EFB, dengan rasio KCl:NPK 2:2 direkomendasikan sebagai yang paling optimal.
