Key Word : Lake Gintung, Light Detector, “X” Detector

Exactly at 02.30 wib date 27 marches 2009 lake gintung can't hold again the water, because there are soil crack around the dike. This crack is initially was caused by tune stricture and decrease the water volume around the dike because there are development aroud lake gintung's dike. The development of solid citizen resident at lake area was primary factor that broken down lake's dike. Because, if there is a weight increase of soil surface, so the tension in soil including soil pore tension will produce increasing. This matter causes decreased stability of the slope. It's the impact of the development around the dike.
Because the increasing of the water volume around the dike, the consequences was the dike can't hold back the big water pressure. So, the dike was broken down and the water soaks hundreds house at moment the occupants stills asleep. Therefore, researcher make tool that can detect artificial lake dike crack. Tool that has made by researcher uses energy conservation laws principle concept, magnetic field, Ohm law, AC work principle, and Fotodioda. The making of this tool, was done as testing from indicator that this tool can works well. study that has done was meant to look for theories and tool work mechanism, upon which reference, so the tool that researcher has made can work as according to law theories that had appear. Researcher hopes that this research can answer and decrease the problem that occured because of the broken down of lake gintung and later can be applied in a state of reality.

ABSTRACTION



Key Word : LDR, Sun Light, lamp, flood detector

It has done making of prototype" Smart House" functioned to turn on the light automatically and to detect flood. The background making this tool was remembering the rarity of national electricity energy that caused electricity use redundantly, and often the happening of flood at indonesia especially at jakarta. This tool work system uses LDR (Light Dependent Resistor) That is functioned as electric switch with make use light intensity in run the function. For flood detector is used water increase (flood) as conductor (electric switch) and to jangle alarm. From experiment result, prototype" Smart House" can turn on the light led automatically by using LDR series as automatic electric switch that makes use sun light intensity. At the time of resistence light of LDR low, that will causes the LED lamp dull. Conversely, at the time of resistence low light intensity LDR was very low, that will causes the LED lamp glow. Besides, this prototype also can detect flood that caused conductor electric switch in bazer to get current from water that rise in pisvot tube, that will make the alarm rang. Therefore, researcher propose so that this tool can be developed furthermore and aplicated to help decreasing electric light use intensity in times of not necessaries. Besides, this tool also intended can help society that live in flood sensitive area, so people always ready to evacuate themself and their valuable things.

Healthy environment is a clean conditIon and unpolluted so it doesn't evoke disease, has important role towards live form to perform the life and preserve it's breed. Various efforts has been done to create healthy environment but polutant that reside in around change the environment order by human activity or by nature process so that environment quality decreased to certain level that causess environment is less or can not functioned again as according to the allotment. Rich environment polutant, is an unhealthy environment and can disappeared the one of the benefit that is far from disease that one of the cause was mosquito bite. Therefore, researcher makes a tool that can create clean air counters polutant and drive out mosquito using air that reside in our around are rich polutant to make it more useful. The tool that was made by the author, is a tool that use parallel electricity principle to moves exhaust fan and sansivieria ectract filterization. The making of this tool, was an efforts to create healthy environment to counter polutan and drive out mosquito so that can work well and can be used as an useful thing. Study that is done was meant to look for theory - theory, principle - priciple, and application principle, as a reference so that the tool that researcher has made can work as according to principle that had appear. Researcher hopes that this research can decrease potential dengue sufferer and create clean air that counters polutant and create healthy environment for the future, can be socialized and applied in a state of reality.

Medicine Supervisor Big Couch and Food (POM) Jakarta, announce investigation and laboratory result towards food sample, like wet noodle, tofu and salty fish. from 98 samples, 56 was positive infected by formaline, like wet noodle. from 23 wet noodle and curly samples, 15 samples positive contains formaline. and so do salty fish from 34 samples, as much as 22 positive samples. While tofu from 41 samples, 46,3 % positive contains formaline. Therefore we do a research to know that, was extract pangium edule reinw can replace the function from formaline as a preservative in food that doesn't dangerous. The result that we got from this research is, pangium edule reinw was proved can be made in the place of natural preservative and not dangerous.

Some this years later, there are many Indonesian children that have less of calcium because there are many of them who have allergies on milk.. It’s the same as lansia, there are many of them who suffer osteoporosis. This matter was caused because they had less consumption of enough calcium. While Brassica Oleracea Var Italica was known can be used as cancer counter, i’ts obvious had many of calcium substances. Therefore, we do a research to detect is Brassica Oleracea Var Italica can be used as food ingredients substituting milk that we form as a candy. The result that we got from this research is, Brassica Oleracea Var Italica proved has a lot of calcium substances. With three Coly Candy consumption, was equal to a glass of milk.

Abstrak Cros Content Study MAN 13

“Hubungan antara sistem CCS (cross content study) dengan motivasi berprestasi siswa MAN 13 Jakarta”

ABSTRAK

Chusnul Chotimah,Eko Prasetiyo,Tiara Sukma Pertiwi, Madrasah Aliyah Negeri 13 Jakarta, Karya ilmiah dalam rangka kegiatan lomba karya llmiah remaja tingkat Jakarta Selatan 2008.

Telah dilakukan penelitan terhadap hubungan antara pengimplementasian sistem CCS (cross content study) dengan motivasi berprestasi siswa di MAN 13 Jakarta, karena kurikulum Madrasah Aliyah memiliki jumlah mata pelajaran yang lebih banyak di banding Sekolah Menengah Atas, hal ini dikarenakan jumlah mata pelajaran yang telah ditetapkan Departemen Agama harus mereka tunaikan. yang akan berdampak langsung pada motivasi prestasi belajar siswa.
Sistem pembelajaran CCS ( cross content study) atau “Silang Beban Belajar” merupakan sistem pembelajaran yang sistematis dan bertahap, tanpa mengurangi jumlah mata pelajaran yang harus diberikan kepada siswa sesuai dengan kurikulum, dengan cara menggabungkan beberapa mata pelajaran non-jurusan untuk dipelajari secara bertahap dalam kurun waktu tertentu.
Dari latar belakang yang telah disebutkan diatas maka masalah yang akan dibahas dalam penelitian ini adalah apakah terdapat hubungan antara sistem CCS (cross content study) dengan motivasi berprestasi siswa. Dalam penelitian ini sample yang digunakan adalah 200 siswa dari MAN (Madrasah Aliyah Negeri) 13 Jakarta. Dalam penelitian ini penulis menggunakan metode survey, dengan menggunakan 2 variabel yaitu sistem CCS (cross content study) sebagai variabel Independen, dan motivasi berprestasi belajar siswa sebagai variabel dependen. Pengumpulan data primer menggunakan kuisioner (diukur dengan menggunakan skala likert) dan wawancara. Untuk menganalisis korelasi dan signifikansi digunakan rumus korelasi Rho Spearman dan t-Test. Dari hasil penghitungan didapatkan hubungan yang signifikan antara sistem CCS (cross content study) dengan motivasi berprestasi siswa. Hubungan antara dua variabel tersebut digolongkan cukup, dan kedua variabel menunjukkan arah yang positif. Penulis berharap penelitian ini dapat bermanfaat untuk masyarakat khususnya bagi siswa MAN 13 Jakarta dan guru, sehingga sistem CCS (cross content study) berdampak pada meningkatnya motivasi berprestasi peserta didik Selain itu penelitian ini juga dapat menjadi bahan evaluasi bagi staff pimpinan MAN 13 Jakarta untuk mengkaji lebih dalam lagi sistem serta teknis pelaksanaan CCS (cross content study) yang telah diterapkan dalam 3 tahun terakhir, sehingga sistem ini lebih bermanfaat bagi siswa.
