ABSTRACT This study aims to (1) determine the levels of the components of the Tenera variety of palm oil compounds including extractives, holocellulose, α -cellulose, and lignin. (2) Analyze the utilization of the pulp of Tenera varieties as pulp raw materials based on their chemical components; (3) application of chemistry learning module to improving student learning outcomes. Determination of extractive substance content with TAPPI test methods Q: 204; lignin content T: 222; holocellulose Q: 9 levels and α-cellulose content with TAPPI test methods T: 204. then lignin, holocellulose and α-cellulose produced from the procedure were characterized by an IR spectrophotometer. The results of the study were module and implemented in ICHO students in SMAN 2 Kota Bengkulu. The data of the research results were analyzed by ANOVA test at 5% level. The results of the characterization of lignin, holocellulose and α-cellulose with FTIR obtained a distinctive peak of the respective functional groups of the macromolecules. From the research also obtained the average value of chemical component content on the palm velvet varieties of tenera according to their part of base, middle, ends with mean for extractive substance 8.49%, 7,87%, 6,74%, lignin 20,7 %, 18.95%, 16.69%. holocellulose 81.57%, 80.33%, 79.24% and αcellulose 44.57%, 43.56%, 43.26%. Based on the results of the variance analysis, the difference in position (base, center, tip) on the palm oil of the tenera varieties on extractive, lignin, holocellulose and α-cellulose substances has significant differences. Based on the chemical component classification of Indonesian wide wood leaf, sheep betera varieties of tenera in all three positions are used as pulp raw materials because they have moderate lignin content, high levels of Holocellulose and moderate levels of α-cellulose. The result of module implementation in students there is a significant difference between pretest and posttest value. The use of modules in learning in science groups can improve student learning outcomes.

Data penelitian dianalisis Data RESPONS MAHASISWA TERHADAP BUKU PANDUAN DAN KEGIATAN PELATIHAN ABSTRACT This study aimed to know the students's response to the guidebooks and training activities entitled "Monitoring Technique of the Cyclemys oldhamii Tortoise " in the ex situ conservation area Taman Pintar University of Bengkulu. The results showed that students responded positively to the guidebooks and training activities. Forestry students was very interested in the field practices related to the technique and monitoring activities of the C.oldhamii tortoise, while MIPA students was interested in knowledge of the habitat, morphology, and its conservation. Forestry students showed the biggest response to conserve C.oldhamii and other tortoises, meanwhile MIPA students was more interested to do the next observations and research about C.oldhamii and other tortoises for thesis research. Forestry and MIPA students could explain the benefits and plans after the training activities "Technique Monitoring of the Cyclemys oldhamii Tortoise" well. ABSTRACT This study aims to inventory the type of necton, knowing the structure of the necton community and measuring the critical thinking skills of students of class VII.1 SMPN 1 Ujan Mas Kepahiang. The results showed that the necton obtained from the Taman Pintar pond amounted to 7 species and Pipi Putih Pond totaling 4 species. The necton species in the Taman Pintar pond with the highest KP, KS, and FK values are tin head fish with KP, KR, and FK values respectively 0.102 idv / m2, 75.71% and 83%. While on the Pipi Putih Pond is local catfish species with the value of KP, KR, FK of 0.01 idv / m2, 39.29% and 25%. Then dominance index (H ') in the Taman Pintar pond is 0.61 and C' Pipi Putih pond = 0.76. While the index of diversity of necton species in both ponds also belonged to very low category with H' value of Taman Pintar Pond = 0.28 and H' of Pipi Putih pond = 0.17. The result of Percentage Of Agreement test showed that environment-based learning tools developed are included in the category highly feasible to be tested. Students' critical thinking ability on the perpormance aspect shows 33 ,3 % percentage including critically critical criteria and 66,7 % including critical criteria. While Students' critical thinking ability on the cognitive aspect shows four criteria, that are very critical as 26 %, crittical criteria 40 %, criteria critical enough 27 % and criteria less 7 % Keywords: Nekton, environment-based learning, critical thinking ability ABSTRAK Penelitian ini bertujuan untuk menginventarisasi jenis nekton,mengetahui struktur komunitas nekton dan mengukur kemampuan berpikir kritis siswa kelas VII.1 SMPN 1 Ujan Mas Kepahiang. Hasil penelitian menunjukkan bahwa nekton yang diperoleh dari Kolam Taman Pintar berjumlah 7 Spesies dan kolam Pipi Putih berjumlah 4 Spesies. Spesies nekton pada Kolam Pintar yang memiliki nilai KP,KS, dan FK paling tinggi adalah Ikan kepala timah dengan nilai KP,KR, dan FK secara berturut turut yaiu 0,102 idv/m 2 , 75,71 % dan 83 %. Sedangkan pada Kolam Kura-Kura Pipi Putih adalah spesies lele lokal dengan nilai KP, KR,FK sebesar 0,01 idv/m 2 , 39,29 % dan 25 %. Indeks dominansi (H') di Kolam Pintar adalah 0,61 dan C' Kolam kura-Kura Pipi Putih =0,76. Sedangkan indeks keanekaragaman spesies nekton pada kedua kolam juga termasuk kategori sangat rendah dengan nilai H' Kolam Taman Pintar=0,28 dan H' Kolam Pipi Putih=0,17. Hasil uji Percentage Of Agreement menunjukan bahwa perangkat pembelajaran berbasis lingkungan yang dikembangkan termasuk dalam kategori sangat layak untuk diuji cobakan. Kemampuan berpikir kriitis siswa pada aspek kinerja menunjukkan persentase 33,3 % dalam kriteria sangat kritis dan 66,7 % termasuk dalam kriteria kritis, sedangkan kemampuan berpikir kritis siswa pada aspek kognitif menunjukkan empat kriteria yaitu kriteria sangat kritis sebanyak 26 %, kriteria kritis sebanyak 40 %, kriteria cukup kritis sebanyak 27 % dan kriteria kurang kritis sebanyak 7 %.
