ABSTRACT The research was to determine utilization of organic waste with starter fluid cow rumen raw material for biogas production in March and May 2015. Results of the study are used to enrich the teaching materials in the form of biology modules vocational school Agriculture on the concept of waste management. This research was carried out by two phases: experimentation and enrichment modules. Research conducted experiments using completely randomized design (CRD) non factorial, which consists of 4 treatments and 3 replicates in order to obtain 12 experimental design. If there is a real test there will be a further test Duncans Multiple Range Test (DMRT) at 5%. The parameters observed biogas volume, the color of the flame, calor and power. Enrichment module is performed on the stage of analysis and design. The results showed that the use of organic waste with starter fluid cow rumen could potentially produce methane gas as a source of biogas. Treatment A (25% substrate: 75% starter) are best produce biogas with a biogas volume of 11.57 L, color blue flames, calorific value 5670 J and power 132.98 watts for 28 days of fermentation. The results could be used as an module enrichment for biological subjects Agriculture vocational school on the concept of waste management. Keywords: Module, Organic Waste, Fluid Cow Rumen, Biogas.

Goniothalamus merupakan salah satu genus terbesar Annonaceae yang menjadi sumber ubatan tradisional yang penting di Asia Tengggara. Beberapa bahan bioaktif dari kumpulan terbitan stiril dehidropiron terutama goniothalamin telah dipencilkan dari genus ini dan telah dibuktikan mempunyai potensi sebagai anti kanker. Kandungan goniothalamin yang terdapat pada daun, kulit, batang dan akar daripada 21 spesies Goniothalamus yang terdapat di Semenanjung Malaysia, serta variasi goniothalamin dari lokasi yang berbeza bagi Goniothalamus macrophyllus dikaji secara kuantitatif dengan menggunakan Kromatografi Cecair Tekanan Tinggi (HPLC). Analisis kuantitatif menunjukkan purata peratus goniothalamin yang tertinggi daripada daun boleh di dapati daripada G. fulvus (5.81%), kulit daripada G. tortilipetalus (12.1%), batang (11.3%) dan akar (13.21%) daripada G. macrophyllus. Manakala lokasi pengambilan sampel G. macrophyllus yang terbaik bagi kandungan goniothalamin adalah Hutan Rekreasi Jambu Bongkok Terengganu. Analisis kuantitatif juga menunjukkan bahawa peratus kandungan goniothalamin bagi setiap lokasi dan spesies didapati berbeza. Secara keseluruhan kandungan goniothalamin yang terbanyak boleh di dapati daripada G. macrophyllus, dan kandungan tertinggi adalah dari sampel yang diambil daripada Hutan Rekreasi Jambu Bongkok, Terengganu.

ABSTRACT This study aims to determine the effect of variations in the type of processing of tea (Camellia sinensis L. Kuntze) and the concentration of sugar to ferment kombucha and draft Worksheet Students (LKPD) High School Biology.This study consisted of two phases. The first phase is making kombucha tea using the experimental method completely randomized design (CRD) consisting of 8 treatments and 3 replications. Parameters measured were reducing sugar, total acid concentration, pH and organoleptic levels. The results obtained were analyzed by ANOVA and a further test DMRT at 5% level. The second phase is the phase Design (draft) LKPD sourced from the research phase I. LKPD design consists of two stages, namely Analysis and Design LKPD. The results showed that variations in the type of processing tea and sugar concentration provides significant effect on reducing sugar, total acid concentration, pH and organoleptic levels. The greater the concentration of sugar, the greater the reduction sugar and total acid content of kombucha tea, and increasingly lace pH of the solution. As for organoleptic color, aroma, and taste the best there is on the treatment T1G3 (black tea, sugar 120 grams). The results of the study can be used as a draft Worksheet Students (LKPD) on the material of conventional biotechnology. Key words : Kombucha tea, Tea Processing Type Variation, Concentration Sugar, draft LKPD
