<![CDATA[This study is a development research that aims to develop problem-based e-LKPD on acid and base solutions which is valid, practical, and effective to be used to improve learning outcomes. The development model used in this study referred to the 4-D development model, which consisted of the defining stage, the design stage, the development stage, and the dissemination stage. The one developed was a problem-based electronic student’s worksheet (LKPD). The problem-based e-LKPD developed was then validated by two experts. After validation, a trial was conducted at SMKN 9 Jeneponto in grade X TKJ with a total of 22 students. The results show that the resulting e-LKPD is valid with an average validity value of 3.40 with valid criteria. The practicality test includes: (1) analysis of the teacher's response, the teacher gave a very positive response with an average value of 3.75 which means it is practical and not revised, (2) analysis of students’ responses, students gave a positive response with a percentage of 81.80 very responsive. This problem-based E-LKPD also meets the effectiveness criteria with learning outcomes meeting the effective criteria where the N-Gain of 0.64 increases in learning outcomes which is in moderate category, the percentage of completeness is 81.82% which is in good category.]]>

<![CDATA[This study is a development research which aims at developing CBS (Card Brain Scramble) game media on chemistry bond material to improve cognitive reflective style and learning outcomes which are valid, practical and effective to be applied. The development model used in this study referred to Hannafin and Peck’s development model, which consisted of several stages, namely need analysis stage, design making stage, development stage, and implementation stage. The learning media developed is CBS game media, then validated by two experts. After the validation, the tried out was conducted on the media which was conducted at MAN 3 Makassar in grade X MIPA with the total of 30 students. The results of the study reveal that the CBS game media which had been developed and validated indicate that the mean score is 3.65 with valid criteria. The CBS game media is stated as practical and effective because the practical test based on students' response on the utilization of CBS game media obtains 82.84% with the mean score of 3.31 which is in high level. The CBS game media also meets the effective criteria with the following results: (1) the improvement of cognitive reflective style of students is from 70.88% to 80.27%, (2) the learning outcomes meet the effective criteria which obtains from the mean score of 61% to 80.16%, whereas, the improvement of learning outcomes based on N-gain test is 0.49 which is moderate criteria. Therefore, the result of the study shows that the product of CBS game media developed is categorized as valid, practical, and effective.]]>

<![CDATA[This is a research development. The objective of this study is to develop and discover the validity, practicality, and reliability of the science process skills (KPS) test on Acid Base material in class XI SMA/MA. The instrument development process uses the Plomp’s development model which consists of five phases which include: initial investigation, design, realization/construction, test, evaluation and revision, and implementation. The assessment instruments developed consisted of three aspects being assessed, namely cognitive, affective, and psychomotor aspects. The trial was conducted at SMA Negeri 14 Gowa on students of class XI IPA 4. Validity is obtained based on the resulting validation value category of 2.4 < Ktg ≤ 3.2 so that the results of a valid science process skill assessment instrument were obtained. Reliability was calculated using the Kuder Richardson-20 formula (KR-20) and categorized based on established standards was obtained at 75% so that the results of a reliable science process skill assessment instrument were obtained. Practicality was obtained from the analysis of the questionnaire responses of educators who gave very positive responses and based on the category of value generated by ≥ 61% so that the results of a practical science process skill assessment instrument were obtained. Therefore, science process skills assessment instrument developed has fulfilled aspects of validity, reliability, and practicality and can be used to assess students.]]>

<![CDATA[This research is a quasi-experimental that aimed to find out the effect of discovery learning model toward interests and learning outcomes of students in class XI MIA SMAN 3 Pinrang. Independent variable in the research is discovery learning model and direct instruction and dependent variables is areinterest and learning outcomes of acid-base. The population in this research is all students class XI MIA SMAN 3 Pinrang that consist of six classes. Class XI MIA5 as an experiment group that consist of 31 students and class XI MIA2 as a control group that consist of 33 students. The result data of the research was obtained by interest questionnaires and learning outcomes test on acid-base topic for post test. Data were analysed using descriptive statistics and inferential statistics. The results of hypothesis testing for interest using t-test values obtained at tcount = 3,025 and significance level α = 0,05 with df = 3 and ttable = 1,66 because tcount > ttable it indscate that H0 failed. So the are is effect learning model effect learning model to learning interets of students class XI MIA SMAN 3 Pinrang. While for testing the learning outcomes using Mann-Whitney test obtained at Zcount = 3,48 and significance level α = 0,05 with df = 3 and ztable= 1,64. It shows that there is the effect of discovery learning model toward learning outcomes of students in class XI MIA SMAN 3 Pinrang. Testing correlation for experiment group is obtained rcount = 0,618 on significance level α = 0,05 and rtable = 0,355, so it can be concluded that there is positive correlation interests with learning outcomes in discovery learning model. While testing correlation for control group is obtained rcount = 0,488 on significance level α = 0,05 and rtable = 0,344, so it can be concluded that there is positive correlation interests and learning outcomes in direct instruction.]]>

<![CDATA[Mitra Pengabdian Kepada Masyarakat (PKM) ini adalah mahasiswa pendidikan kimia prodi Pendidikan Kimia, Jurusan Kimia Universitas Negeri Makassar. Mahasiswa kimia membutuhkan kemampuan dan konsep yang jelas tentang ilmu spektroskopi guna memahami symbol-simbol yang mewakili penentuan struktur suatu senyawa. terutama pemahaman tentang spektrum Spektrosfotometri Infra Merah (FTIR), hanya saja mahasiswa mendapatkan kesulitan dalam mengolah hasil FTIR yang pada akhirnya menjadi boomerang bagi mahasiswa kimia terutama bagi mahasiswa Pendidikan kimia. Spektrosfotometri Infra Merah (FTIR), adalah salah satu metode penentuan gugus fungsi suatu molekul berdasarkan interaksi molekul dengan radiasi elektromagnetik dengan kisaran Panjang gelombang 0.75-1000 µm. dengan menggunakan Metode Transfer ilmu dan pengetahuan (IPTEKS) yang dilakukan oleh tim pengabdi melalui proses mendengar, mengetahui, mencoba, mengevaluasi dan melaksanakan memberikan hasil yang cukup signifikan. Dimana dari hasil pretest yang sebelum hampir 60% belum dapat menginterpretasikan hasil kromatogram FTIR setelah mengikuti PKM ini, meningkat menjadi 70% mampu mengerjakan soal kromatogram FTIR, dimana berdasarkan survey hal ini disebabkan cara panitia PKM dalam menjelaskan materi sangat mudah dipahami oleh peserta.]]>
