Abstract

Berdasarkan hasil pendataan oleh Badan Pusat Statistik (BPS) bahwa pencemaran terbesar adalah pencemaran air, diikuti pencemaran udara dan tanah. Salah satu penyebab pencemaran air tersebut berasal dari limbah rumah tangga dan limbah industri. Atas dasar permasalahan tersebut penelitian ini bertujuan meningkatkan kualitas fisik air dengan memanfaatkan limbah kulit pisang. Untuk proses penelitian yang dilakukan adalah air limbah difiltrasi menggunakan serbuk simplisia kulit pisang kepok dengan variasi jumlah media filtrasi dan waktu filtrasi. Hasil yang diperoleh terjadi peningkatan tingkat kejernihan air limbah dari warna kecoklatan menjadi bening. Untuk nilai pH dan TDS pada variasi jumlah media filtrasi yaitu dari pH awal 4,9 dan TDS 477 mg/L menjadi pH 5,7 dan TDS 316 mg/L (filtrasi 30 g kulit pisang), pH 6,3 dan TDS 310 mg/L (filtrasi 50 g kulit pisang), pH 6,6 dan TDS 333 mg/L (filtrasi 70 g kulit pisang), pH 6,9 dan TDS 348 mg/L (filtrasi 90 g kulit pisang). Kemudian untuk variasi waktu filtrasi didapatkan hasil yaitu pH 5,3 dan TDS 409 mg/L (filtrasi 3 jam), pH 5,5 dan TDS 342 mg/L (filtrasi 5 jam), pH 6,3 dan TDS 314 mg/L (filtrasi 7 jam), pH 6,6 dan TDS 303 mg/L (filtrasi 9 jam ). Berdasarkan data perubahan pH dan TDS serta tingkat kejernihan air tersebut dapat disimpulkan bahwa kulit pisang kepok mempunyai efektivitas cukup tinggi dan berpotensi sebagai biosorben ramah lingkungan dan dapat dikembangkan lebih lanjut dengan proses aktivasi dan uji parameter lainnya untuk mengurangi dampak pencemaran lingkungan.

Abstract

Based on the information obtained student learning outcomes are still relatively low. The reason for this is still applied learning model that is dominated by teachers, so that students are not actively involved in the learning process. To overcome this, efforts have been made to change with group learning. The result of group learning was not maximal because of the dominance in the group, so the students' understanding is uneven. As a result student learning outcomes are still many below  assigned the minimum criteria. Based on this, the authors conducted a cooperative learning model study with pair checks approach. Application of this learning model is expected to improve student achievement as a whole. That is because in this learning model students are trained sharing skills by working in pairs and pairwise checking arrangements, so no more terms dominate in the group. This form of research is an experiment with pretest and posttest design. The research sample consisted of two classes of X SMAN 3 Duri, class X.7 as experiment class and class X.10 as control class. Processed data are pretest and posttest values on hydrocarbon subject. Hypothesis test data processing using t-test formula obtained t-quantification bigger than t-table that is 2,65> 1,67, meaning hypochetical application of cooperative learning model with pair checks approach can improve student achievement on hydrocarbon subject in SMAN 3 Duri accepted. Keywords: Cooperative Learning, Pair Checks Approach, Learning Achievement

Abstract

Environmental problems are global issues caused by low public awareness of the importance of environmental management. One factor is the environmental pollution generated by waste. The problem of waste is closely related to the lifestyle and culture of the community. If waste management does not get the attention of various parties, it will make environmental conditions worse and human health conditions also go down. Therefore, awareness of the importance of waste management needs to be instilled since childhood. This activity was carried out at SDN 007 Pangkalan Baru, Siak Hulu District, Kampar Regency. Based on the activities that have been carried out, most students do not yet understand how to classify and process waste to be economic value so the education should be given to the students. This activity can be said successful because of the high enthusiasm and participation of students in answering the questions that given based on the material that has been delivered.

Abstract

Heavy metal is the most hazardous of contaminats group. Our ecosystem has been contaminated by high concentrated of heavy metal that was generated from human activities such as industrial. On this research heavy metal content due to illegal gold mining (PETI) activities in Singingi river, Riau was measured. This was held because the river has degradation of its quality immediately. It was marked by high turbidity and declining of organism in that river. The choice of determining the content of heavy metal Pb or lead because we know that gold processing is not only used by mercury but also used by lead and cadmium to bind gold. The three metals are used to bind the gold and separate it from soil and stone in from sulfide.. This research used survey method with purposive sampling based on the rise location of PETI activities. Sample was measured at 4 point that started from the nearest and up to the furthest of PETI activities. The result of lead measurement was 0, 00382 mg/L; 0,00165 mg/L; 0,00124 mg/L and 0,02525 mg/L, respectively. The results obtained indicate that the river has been contaminated with lead metal although if were compared with the quality standard of heavy metal in aquatic Lead still allowed with the number of quality standard for lead is 0,03 mg/L. Keywords : PETI activities, heavy metal measurement, Lead (Pb) Singingi river

Abstract

ABSTRACT Long-term consumption of nuggets can lead to: increasing heart attacks, increasing body weight, triggering diabetes and triggering high blood pressure. That is because in processed food manufacturers usually add preservatives, excessive MSG and imbalanced nutrition. Because there are still many people, especially mothers in partner neighborhoods in Perhentian Marpoyan, who often complain that their children do not like to consume vegetables, and many make processed nuggets as manufacturers for their children, in this service we provide a presentation on how to process Nugget. Gambas are rich in antioxidants, so they are very good for consumption especially for the growth process of children. The existence of this community service was very welcomed by the local residents, this can be seen from the enthusiasm of residents asking questions related to the problems presented regarding the processing of nuggets as well as from the impression of some residents who want this kind of activity to be carried out continuously so that more people feel the benefits and they will try to apply the knowledge from the education that has been carried out. Keywords: fast food, nuggets, gambas, antioxidants ABSTRAK Konsumsi nugget dalam jangka panjang dapat menyebabkan: meningkatkan serangan jantung, meningkatkan berat badan, memicu diabetes dan memicu tekanan darah tinggi. Hal itu dikarenakan didalam makanan olahan pabrikan biasanya ditambahkan pengawet, MSG yang berlebihan dan nutrisi yang tidak seimbang. Dikarenakan masih banyaknya masyarakat terutama Ibu-Ibu di lingkungan mitra di kelurahan Perhentian Marpoyan yang sering mengeluhkan anak-anaknya tidak suka mengkonsumsi sayuran, serta banyak yang menjadikan nugget olahan pabrikan sebagai bekal anak-anak mereka, pada pengabdian ini kami memberikan pemaparan bagaimana dapat mengolah  Nugget Gambas yang kaya Antioksidan, sehingga sangat baik dikonsumsi terutama untuk proses pertumbuhan anak-anak. Adanya kegiatan pengabdian  ini sangat disambut baik oleh warga setempat, hal ini dapat dilihat dari antusiasnya warga mengajukan pertanyaan-pertanyaan sehubungan masalah yang dipaparkan mengenai pengolahan nugget serta dari kesan beberapa warga yang ingin kegiatan sejenis ini terus dilakukan secara berkesinambungan sehingga lebih banyak lagi yang merasakan manfaatnya dan mereka akan mencoba  mengaplikasikan pengetahuan dari edukasi yang telah dilaksanakan. Kata Kunci: makanan cepat saji, nugget, gambas, antioksidan

Abstract

One of the practical and efficient products of biomass processing is briquettes. Briquettes are densified products in the form of cubic, prism, or cylindrical shapes. One of the biomass produced from abundant agricultural waste in Riau Province is coconut coir. This is because Riau Province is one of the largest coconut-producing regions in Indonesia. The utilization of coconut coir waste is currently still limited to crafts, fuel, and planting media. This study aims to produce briquettes from a waste of old coconut coir and young coconut coir with the stages of the research process including cleaning, drying, grinding, adding adhesive, and densification. The resulting briquettes were then subjected to laboratory tests to determine the physical characteristics of the briquettes based on SNI No. 1/6235/2000 and structural characteristics using SEM and TG/DTG. The results showed that laboratory tests for old coconut coir briquettes and young coconut coir based on water content were 28.11% and 29.72%; based on ash content are 1.59% and 2.21%; based on the carbon content are 25.10% and 24.94%, and the heating value is 3019.54 cal/g and 3137.03 cal/g. For SEM analysis, the surface morphology of the briquettes looked smooth and there was no fragmentation indicating that the biomass was perfectly bonded with the binder used. Meanwhile, in the TG/DTG analysis, the results showed that there had been a mass decrease of around 90% for old coconut coir briquettes and 78% for young coconut coir briquettes at a temperature of around 450oC
