Abstract

Since environmental issue is often discussed, our ecosystem is getting more fragile. At the same time, basic human needs should be full filled fast by improving productivity and of course this will require natural resources. Indicator for this is exactly could be seen as to what extent human being has changed his/her consumer behavior, in term of how fast he/she utilize space available at a given ecosystem. This measurement called “ecological footprint (EF).” How students’ EF affected by environmental personality and gender is research problems of this study. An ex post facto method has been applied by involving 258 faculty of technology students (115 male and 143 female), State University of Jakarta as a sample. Environmental Personality (EP) measured based on “big-five personality” related to environmental issues such as openness, conscientiousness, extraversion, agreeableness, and emotional stability (30 items, only 19 was valid and its reliability was .74) and EF refers to measure of water, transportation, foods, and others, utilized by students in daily life. Data have been analyzed by one-way ANOVA, F-test, t-test and chi-square. The research results reveal that there is significant difference (α = .10) of students EF between students who high, medium, and low in EP. It means that EP did affect students EF. If male and female students EP were separated, again gender did affect students EF which come up with the interpretation that gender equality was neglected in higher educational system. Moreover, it was found that EP does not affect as a single factor, but it depends on students’ gender as well because there is significant dependency between EP and students gender in determining students EF (X2-cal > X2-table). Based on those finding, it could be recommended that some factors such as students locus of control, personal responsibility, situational factors, or intention to act with other models of research could be taken into consideration. In future research, to make sure that EF might not been affected by a single factor.

Abstract

This research aims to evaluate the potential of pineapple peel as a raw material for making activated carbon, as well as comparing the effectiveness of NaOH and NH4OH activators in the activation process. Activated carbon is produced through a carbonization and chemical activation process, then its quality is tested based on the Indonesian National Standard (SNI) 06-3730-1995. The research results show that activated carbon from pineapple peel meets SNI standards in terms of ash content and water content, with each not exceeding the maximum limits of 10% and 15%. The yield of activated carbon activated with NH4OH (87.5%) was higher than NaOH (79.4%). In addition, the water content of activated carbon with NH4OH (1.07%) is lower than NaOH (1.42%). Although the iodine absorption capacity of activated carbon from pineapple peel is still below the minimum SNI standard (750 mg/g), NH4OH shows better results in adsorption of the heavy metal Cu (0.0041 mg/g) than NaOH (0.0015 mg/g ). The FTIR spectrum shows the presence of diverse functional groups, indicating complex chemical interactions. Based on the results of this research, pineapple peel has good potential as a raw material for activated carbon, with NH4OH as a more effective activator in improving the quality and adsorption ability of activated carbon.

Abstract

Background: Bahan yang digunakan dalam pembuatan sabun cuci piring biasanya menggunakan bahan aktif kimia sintetik yang memiliki dampak negatif bagi lingkungan yaitu dapat mencemari lingkungan. Berdasarkan hal tersebut maka, pengabdian ini dilakukan untuk memanfaatkan daun sirih dan daun binahong sebagai bahan dasar pembuatan sabun cuci piring yang ramah lingkungan dan dapat menciptakan peluang usaha baru yang memberikan pendapatan kepada warga desa. Metode: Kegiatan pengabdian kepada masyarakat ini bermitra dengan kelompok PKK Desa Balong Kec. Ujung Loe Kab. Bulukumba, yang terdiri dari 20 orang anggota. Kegiatan yang diusulkan pada PKM ini adalah sosialisasi kandungan senyawa aktif daun sirih dan daun binahong, pelatihan teknik pembuatan dan proses produksi pengolahan daun sirih dan daun binahong menjadi sabun cuci piring, pelatihan teknik pengemasan dan pelabelan produk, pelatihan manajemen usaha dan pemasaran produk, evaluasi program, serta pendampingan. Hasil: Pengolahan daun sirih dan daun binahong menjadi sabun cuci piring sangat memberikan dampak positif terhadap ibu PKK di Desa Balong, selain mereka dapat membuat sabun cuci piring sendiri, mereka juga dapat memanfaatkan tanaman yang mereka tanam selama ini yang kurang dimanfaatkan. Daun sirih dan daun binahong termasuk tanaman yang mengandung senyawa-senyawa kimia dengan bioaktivitas sebagai antibakteri. Kesimpulan: Dari pelaksanaan kegiatan pengabdian masyarakat yang telah dilakukan dapat disimpulkan bahwa, melalui sosialisasi dan pelatihan ibu-ibu PKK dapat mengetahui manfaat penggunaan daun sirih dan daun binahong dalam pembuatan sabun cuci piring yang ekonomis dan ramah lingkungan.
