"The measurement of specific surface area of porous materials has long been important in physical sciences and is currently growing in importance in applied and environmental science. Numerous systems have been developed for surface area measurement by gas adsorption. Commercial systems are available which can measure a wide range of absolute surface area with relative ease. However, their cost is often prohibitive. In this study, an inexpensive apparatus for surface area measurement has been set up to be used for measuring supercritical adsorption of CO2. The Ono-KondoLattice model was used to represent the adsorption isotherm and to determine the surface area. The results of surface area determination using CO2 adsorption combined with OK model have been compared to the numbers obtained from nitrogen BET method. For surface area determination of zeolites and activated carbons, the new methodgive reasonable agreement results (within 10% deviation) compared to the results obtained from nitrogen BET method. In addition, thenew method also gives more reasonable results for surface area determination of coals. As known, the nitrogen BET method gives almost zero of coals? surface area. This might due to the characteristic of the coals? structure that might be change (the pores are closed) during the cooling process in nitrogen BET method. Moreover, the new method can also be used to determine the surface area of porous materials using CO2 adsorption data at various temperatures without sacrificing their accuracy."

"ABSTRAKDesa Tugu Utara dan Tugu Selatan, Puncak, Kabupaten Bogor, merupakan daerah yangbanyak dikunjungi turis Timur-Tengah. Kehadiran para turis menjadikan masyarakatnyamengalami ketergantungan secara ekonomi terhadap mereka. Hal ini membuatmasyarakat menjadi permisif terhadap persoalan-persoalan di lingkungannya. Situasimasyarakat berdampak pula terhadap para remajanya. Para remaja menjadi engganmelakukan sesuatu atas persoalan-persoalan yang dirasakan. Program intervensi iniditujukan untuk memberikan penguatan Motivasi Instrinsik untuk Peduli Lingkunganpada remaja, sehingga diharapkan mereka lebih terdorong untuk bertindak ataspesoalan-persoalan lingkungan di sekitarnya. Intervensi dilakukan menggunakanpendekatan Experiential Learning Technique. Uji hipotesis dengan analisis statistikWilcoxon Signed-Rank Test (p=0,000, los p<0,05) membuktikan bahwa programintervensi dapat memperkuat motivasi intrinsik untuk peduli lingkungan padapartisipan.

ABSTRACTTugu Utara and Tugu Selatan, Puncak, Kabupaten Bogor, there are visited by manytourists from Middle-East. The presence of tourists makes the people had sufferedeconomic dependence on them.This made people become permissive to problems ontheir environment. The situation of society had an impact on the youth. The teenagerswould be reluctant to do something about the perceived problems. This interventionprogram is intended to provide reinforcement for the intrinsic motivation to care theenvironment in adolescents, so hopefully they are more compelled to act on the issuessurrounding environment. The intervention was performed using Experiential LearningTechnique approach. Test the hypothesis using statistical analysis Wilcoxon Signed-Rank Test (p=0,000, los p<0,05) proved that intervention programs can strengthenparticipant?s intrinsic motivation to care for the environment."

"[ABSTRAKTulisan ini berfokus pada interpretasi kejahatan pencurian kendaraanbermotor roda dua yang terjadi di Kampus UI Depok ke dalam pemetaansederhana. Pemetaan sederhana dibuat dengan menggunakan teknik overlay(tumpang susun) diatas peta wilayah UI Depok. Overlay dibuat denganmenggunakan plastik mika transparan yang kemudian ditandai dengan titik untuk menunjukkan suatu lokasi. Overlay yang dilakukan menghasilkan pemetaan kejahatan pencurian kendaraan bermotor yang terjadi di Kampus UI Depok. Selanjutnya pemetaan sederhana yang dihasilkan dianalisis dengan menggunakan crime pattern theory. Hasil dari penulisan ini menunjukkan bahwa pemetaan kejahatan dengan teknik sederhana memiliki beberapa keterbatasan. Sehingga memperlihatkan bahwa pemetaan dengan pemanfaatan SIG (Sistem Informasi Geografis) berbasis teknologi menjadi suatu hal yang penting.

ABSTRACTFocusing on motorcycle theft that happened at UI Depok Campus, thispiece will interpret that particular crime into a simple crime mapping. Simplemapping was made using overlay technique over UI Depok area map. The overlayitself was made using transparent mica plastic filler which later was marked withdots to showed a particular location. The overlay would then produce the crimemapping of motorcycle theft that happened at UI Depok Campus. Furthermore,the overlay produced was analyzed using the crime pattern theory. The final resultshowed that crime mapping which used simple technique had few limitations, ofwhich leaded into a conclusion that the using of GIS (Geographical InformationSystem) into the crime mapping is an important thing to do. , Focusing on motorcycle theft that happened at UI Depok Campus, thispiece will interpret that particular crime into a simple crime mapping.

"Ketidaknyamanan pada ibu Post Sectio Caesarea (SC) salah satunya adalah konstipasi. Hal ini disebabkan rasa nyeri pada bekas jahitan SC yang mengakibatkan mobilisasi ibu menjadi terbatas dan memengaruhi gerak peristaltik ususnya. Penggunaan anestesi selama prosedur operasi juga turut memengaruhi masalah konstipasi pada ibu post SC. Salah satu intervensi yang mampu mengatasi permasalahan konstipasi tersebut adalah menganjurkan ibu melakukan mobilisasi aktif dengan terapi berjalan dan intervensi Physio Bowel Emptying Technique (PBET). Karya ilmiah ini bertujuan untuk menganalisis asuhan keperawatan pada ibu post sectio caesarea yang mengalami konstipasi dengan tindakan mobilisasi aktif terapi berjalan dan PBET. Metode yang digunakan adalah case study pada pasien post SC yang sudah berada di rumah, yaitu di Kecamatan Ciracas, dan mengalami konstipasi. Hasil evaluasi setelah tindakan menunjukkan bahwa ibu post sectio caesarea cenderung merasa lebih rileks dan nyeri BAB berkurang sehingga ia merasa lebih nyaman. Mobilisasi aktif dengan terapi berjalan serta intervensi PBET direkomendasikan untuk mengurangi masalah konstipasi pada ibu post SC.

One of the discomfort in post caesarean section (C-section) mother is constipation. This is due to the pain in the C-section suture mark which causes the mothers mobilization to be limited and affects her intestinal peristalsis. The use of anesthesia during surgical procedures also triggers constipation problem in post C-section mothers. One of the interventions that can overcome the constipation is to encourage mothers to carry out active mobilization with walking therapy and getting Physio Bowel Emptying Technique (PBET). This scientific paper aims to analyze nursing care for post caesarean section mothers who experience constipation by applicating active mobilization with walking therapy and PBET. The method used is a case study on post C-section patients who are already at home, namely in Ciracas District, and experiencing constipation. The results of the evaluation after the action showed that post C-section mothers tended to feel more relaxed and had less pain when defecating so that they felt more comfortable. Active mobilization with walking therapy as well as PBET interventions are recommended to reduce constipation problems in post C-section mothers.
