Abstract

Seiring dengan peningkatan jumlah penduduk di daerah pesisir, tekanan terhadap ekosistem pantai semakin meningkat pula.? Untuk mengetahui dampak dari aktifitas anthropogenik terhadap status hara (karbon, nitrogen dan fosfor) pada lamun telah dilaksanakan penelitian pada dua pulau di Kepulauan Spermonde yakni Pulau Barranglompo dan Bonebatang.? Kedua pulau ini mendapat tekanan anthropogenik berbeda. Sampel diambil dari daun lamun Enhalus acoroides pada tiga stasiun dengan jarak berbeda dari garis pantai pada masing-masing pulau.? Hasil pengukuran hara menunjukkan bahwa konsentrasi nitrogen di Pulau Barranglompo jauh lebih tinggi dibandingkan Pulau Bonebatang.? Nilai rasio C:N yang lebih rendah dan nilai rasio N:P yang lebih tinggi di Pulau Barranglompo memperkuat hal ini. Perbedaan ini mengindikasikan pengaruh dari pengayaan hara akibat aktifitas anthropogenik yang semakin meningkat. Hal ini didukung oleh nilai Total Padatan tersuspensi yang jauh lebih tinggi di Pulau Barranglompo dibandingkan Pulau Bonebatang. Aktifitas anthropogenik yang paling potensial mempengaruhi komposisi hara di Pulau Barranglompo adalah pembuangan sampah rumah tangga dan aliran limbah cair dari rumah penduduk di sekitar pantai. Kata kunci: lamun, hara, rasio C:N:P, aktifitas anthropogenik, Barranglompo, Bonebatang As human population increase in coastal areas, significant pressure to the coastal ecosystem increase as well.? In order to reveal possible impacts of anthropogenic activities to the nutrient status of seagrasses, a study has been done in two small islands within Spermonde Archipelago i.e. Barranglompo and Bonebatang Islands. Currently, these two islands are facing different anthropogenic pressure.? Samples of seagrass Enhalus acoroides were collected from three stations based on their different distances from the shoreline.? Results of the nutrient measurements showed that nitrogen concentrations in Barranglompo Island were significantly higher than those in Bonebatang Island.? This was supported by lower C:N ratios and higher N:P ratios in Barranglompo Island.? This difference indicated influence of nutrient enrichment due to increased anthropogenic activities.? Significantly higher Total Suspended Solid (TSS) values were also a strong evidence of this process.? Potential anthropogenic activities affecting nutrient composition in Barranglompo Island are domestic sewage disposal and drainage of liquid household sewage. Key words: seagrass, nutrient, C:N:P ratio, anthropogenic activities, Barranglompo,? Bonebatang

Abstract

Quality Control (QC) is one of the most important components in the manufacturing process. The aim is to determine whether a product is feasible to market. One aspect of QC is the size / dimension of the object to be made. If the size is still within the range of tolerance, then it has passed the QC in terms of size, but if not then it includes a failed product. The problem encountered is that it takes a long time to take measurements, especially objects in the third dimension where each part is different as microdrill, zipper etc. To overcome this weakness, a CCD camera is used as a sensor to record images and then use LabVIEW software to analyze the size of the recorded image. This is a preliminary study so that it is only done for objects with two dimensions with square and circular shapes. From the research that has been done, the measurement with the camera gives results that are almost the same as the use of calipers where the standard deviation fluctuates from 0.3 to 23.8 for circles and 0.54 to 32.05 for squares. Furthermore, the time needed to do one measurement process with the camera ranges from 201 ms to 338 ms whereas using the calipers takes 3 to 5s

Abstract

This paper focuses on fiqh (Islamic jurisprudence) learning at the high school level. The aim of the research is to measure the extent to which the achievement of fiqh learning at the high school level can be improved with the blended learning method. Concept analysis method is used to understand the concept of blended learning and explain its implementation in the field. This research is a class action research which refers to the Kemmis model consisting of four components namely planning, implementation, observation and reflection. It is expected that the blended learning method can improve the achievement of fiqh learning at the high school level. The research found that in the first phase of classroom action research, students have not been able to adjust themselves to learning using the blended learning method, especially with the Kahoot application. Most students are still fixated on conventional learning. Basically, however, the blended learning method can generate high attractiveness for students. Enthusiasm and focus on learning become higher. The feedback obtained shows that 100% of students claim to have learned something, 100% recommend it to be reused and 80% welcome this method with fun. The study suggests that the composition in the placement between direct communication with face to face and online must be appropriate, so that an improvement in fiqh learning can be achieved. Keywords: blended learning, fiqh learning, learning outcome

Abstract

The use of groundwater as a source of fresh water to the people would become a problem when it contains of Fe and Mn. This happens because in the ground water there is no directly contact with the air outside and the weathering of rocks, so that Fe and Mn in the ground water is still soluble. Meanwhile the amount of Fe and Mn in the ground is never the same in every location. This case could be some impacts to people’s kidney health. In this study, content of Fe and Mn in the ground water will be reduced by using Clay filter media. This study uses 3 wells water samples character with different level of Fe and Mn in sample A is 0.001 mg / l Fe, 0.16 mg / l Mn, sample is B 0.019 mg / l Fe, 0.05 mg / l Mn, and sample C is 3,242 mg / l Fe, 0.27 mg / l Mn. The height level of water influence to the Clay filter becomes the consideration in this study, they are 50 cm, 100 cm and 150 cm. Clay Filter is operated for 12 hours continuously with taking the reuslt of filtration sampling per 2 hours. Based on the research, this study finds the operating time to decrease the concentration of Fe and Mn with Clay Filter optimally from the three height levels in all kinds of different water samples and its categorization has reached 100% at the fourth hours.

Abstract

Menulis (Writing) adalah suatu proses untuk memahami makna atau memperoleh informasi yang ada di dalam teks bacaan. Oleh karena itu, menulis yang diiringi dengan pemahaman membuat siswa dapat menambah ilmu pengetahuan dan informasi yang terdapat di dalam teks atau gambar yang dipahami. Selain itu, kesuksesan siswa dalam belajar biasa dilihat dari seberapa jauh siswa memahami sebuah gambar. Pengajaran menulis tidak hanya mengajarkan siswa cara menulis teks yang dipahami. Namun pada kenyataannya masih banyak siswa yang masih belum memiliki kemampuan yang baik dalam menulis dalam kalimat Bahasa  Inggris dan memahami makna yang mereka pahami untuk menghasil penulisan teks narrative yang baik.Pada journal ini, penulis membahas tentang salah satu strategy pembelajaran writing yang dapat diaplikasikan di tingkat sekolah menengah yaitu dengan menggunakan strategy attribute webs. Strategy ini diharapkan bisa meningkatkan motivasi siswa dalam menulis teks narrative. Salah satu keuntungan dari strategy ini adalah siswa lebih kreatif dalam menyampaikan hasil pemikirannya dan membuat suasana belajar tidak pasif. Dengan penerapan strategy ini siswa akan lebih tertarik untuk belajar memahami sehingga akan dapat meningkatkan motivasi untuk berlatih dan meningkatkan cara belajar siswa dalam belajar menulis teks narrative yang bagus.

Abstract

Watershed overcoming deteriorates in its function was indicated by increasing soil erosion and land degradation. The research aims were to determine and map critical land degradation levels and to chose options of practical conservation concepts in Manna watershed. The Manna watershed lays on 102°51'38.2" - 103°10'57.8" long, and 04°0'39.6" - 4°29'38.0" alt covering 72,899.9 ha. The analysis procedures to determine land degradation levels based on Ministry of Forestry Rule (No. P.32/Menhut-11/2009), Procedures of Technical Design on Forest and Land Rehabilitation in Watershed (RTkRHL-DAS). The results showed that the Manna watershed divided in three land uses functions namely protected forest, limited timber forest, and agricultural cultivated areas/settlement. The land starting overcome degradation in covered by 35,318.6 ha or 48,77% of the watershed based on digital mapping using ArcGIS 10.1 software. The lands that categorized the critical level of degradation covered 7,989.5 ha or 11,03% of the watershed, and classified in the high critical level were 169.8 ha or 0,23% of the watershed. Options of conservation practice on the degraded lands in the Manna watershed should implement agro-forestry models because of the physiographical landscape in this area covering by waving to hilly landforms. On the protected forest and limited timber forest should develop agro-forestry with collaborative approaches through social engineering and social forestry. Re-establishing land use of the Manna watershed based on functions of land is the wise options for the sustainable environmental concepts

Abstract

Dugong is the only herbivory mammals in the sea and mainly feed on seagrasses. Population of dugong tends to decrease in all ofits range as an impact from hunting, fishing activities and habitat degradation. In South Sulawesi-Indonesia, recent informationabout dugong population is unknown due to limited observation. Last dugong existence reported from Barranglompo Island in1991. This research aim to reveal the existence of dugong in Spermonde Archipelago. Result of this study showed from 1992to 2017, only 6 individu of dugong were observed. In 2006, one live dugong accidentally found roaming near Samalona Island.This encounter was successfully recorded by video camera. Four years later, one dead dugong found trapped in fishing net nearLantangpeo village, Tanakeke Island and sold to local fishermen for consumed. In 2014, one dugong grazing track was alsofound in Tanakeke Island near Balandatu Village. Information from 2016, reported two dugongs in seagrass meadow aroundPuntondo and Laikang Bay. Last report on 31 January 2017, showedone decomposed body from young dugong stranded inBarranglompo Island. The death cause remaining unknown. From interview with some witnesses and local fishermen, dugongaccidentaly found trapped, drown and dead in fishing net that set up around seagrass meadow. Captured dugong will on sale andslaughtered for its meat.With only once encountered alive in 25 years (which recorded by video camera), it can be concludedthat dugong population in Spermonde archipelago were extremely rare, heavily threatened and facing extinction.Keywords: dugong, sighting, Spermonde Archipelago, South Sulawesi
