AbstrakEkstrak etanol daun sendok mengandung banyak zat aktif, termasuk triterpenoid dan flavonoid yang memiliki efek anti proliferatif, anti angiogenesis dan menginduksi apoptosis sel kanker. Hipergastrinemia dapat menginduksi over-ekspresi Gen Regenerating 1, menekan produksi Caspase 3 dan perubahan histopatologi jaringan mukosa lambung. Penelitian ini menganalisis pengaruh pemberian ekstrak etanol daun sendok terhadap penghambatan over ekspresi gen Regenerating 1, peningkatan kadar Caspase 3 dan perubahan histopatologi jaringan mukosa lambung tikus model hipergastrinemia. Penelitian ini dilakukan secara eksperimental dengan post test only with control group design. 28 tikus putih dibagi menjadi empat kelompok. Kelompok I (kontrol) diberi Omeprazol dosis 8mg/200gBB tikus/hari, Ciprofibrate dosis 12,5mg/200gBB tikus/hari dan 3 kelompok studi (Kelompok II, III dan IV diberi Omepr azol dosis 8mg/200gBB tikus/hari, Ciprofibrate dosis 12,5mg/200gBB tikus/hari dan ektrak etanol daun sendok masing-masing dosis 50mg, 100 mg dan 200mg per 200gBB tikus/hari). Semua hewan coba dikorbankan dibawah pengaruh anestesi setelah perlakuan selama 2 bulan. Sampel darah dan gaster hewan coba diambil untuk pemeriksaan kadar gastrin dan Caspase 3 dengan metode ELISA, ekspresi Gen Regenerating1 dengan RT-PCR serta histopatologi jaringan mukosa lambung. Kadar gastrin hewan coba meningkat 3-4 kali kadar gastrin normal (>169 pg/mL). Rerata ekspresi Gen Regenerating 1 terendah terjadi pada Kelompok III (1,226±0,108) Analisis statistik menunjukkan terdapat perbedaan ekspresi Gen Regenerating 1 secara bermakna antara Kelompok III dengan kontrol (nilai p= 0,016;IK 95%). Rerata kadar Caspase 3 tertinggi terdapat pada IV (0,603±0,172ng/mL). Analisis statistik menunjukkan terdapat perbedaan kadar Caspase 3 secara bermakna antara kelompok IV dan Kelompok lainnya (nilai p <0,05;IK 95%). Gambaran histopatologi mukosa lambung menunjukan atropi dan tidak terdapat perbedaan ketebalan jaringan mukosa lambung secara bermakna diantara kelompok penelitian (nilai p=0,092; IK95%). Pemberian ekstrak etanol daun sendok mencegah over-ekspresi Gen Regenerating 1 dengan dosis 100mg/200gBB/hari, meningkatkan kadar Caspase 3 dengan dosis 200mg/200gBB/hari tetapi pada dosis penelitian yang digunakan tidak dapat menghambat perubahan histopatologi jaringan mukosa lambung tikus model hipergastrinemiaKata Kunci: Ekstrak etanol daun sendok, Over ekspresi Gen Regenerating 1, Caspase 3, Histopatologi mukosa lambung, Model HipergastrinemiaAbstractPlantago major L has a lot of active substances, including triterpenoid and flavonoid that show anti proliferative effect, anti angiogenesis and induce cancer cells apoptosis.

This study was to evaluate the effect of Plantago major L extract.on inhibition of Regenerating 1 gene overexpression, increasing of Caspase-3 level and histopathologic alteration of gastric mucosal tissues on hypergastrinemic rat (Rattus norvegicus) model. By experimental study and post test only with control group design, 28 of rats was divided in to 4 groups. Group I as a negative control was given Omeprazole 8mg/200gbw rat and Ciprofibrate dose 12,5 mg/200gbw rat/day and aquadest per oral. Group II was given Omeprazole 8mg/200gbw rat and Ciprofibrate dose 12,5 mg/200gbw rat/day and Plantago major L. extract 50mg/200gbw rat/day per oral. Group III was given Omeprazole 8mg/200gbw rat and Ciprofibrate dose 12,5 mg/200gbw rat/day and Plantago major L. extract 100mg/200gbw rat/day per oral. Group IV was given Omeprazole 8mg/200gbw rat and Ciprofibrate dose 12,5 mg/200gbw rat/day and Plan tago major L. extract 200mg/200gbw rat/day per oral. They were killed after 2 month intervention under anaesthetic. Blood sample and gaster organs were collected for measurement of gastrin and caspase 3 level by using ELISA method, expression of Regenerating 1 gene by RT-PCR and histopatological examination of gastric mucosal tissues. There were increasing of gastrin level of rats up to 3-4 times fold compared to normal level and to indicate hypergastrinemic condition. The lowest average of Regenerating 1 gene expression was found on Group III (1,226±0,108). Statistic analysis show that there were significantly difference of Regenerating 1 gene expression between group III and Control (p= 0,016; 95%CI) The highest average of Caspase-3 level was found on Group IV(0,603±0,172ng/mL) and there were significantly difference of caspase-3 level between group IV and the other Groups (p< 0,05; 95%CI). There were atrophic process on gastric mucosal tissue but there were not significantly difference of gastric mucosal thickness between group (p= 0,092; 95%CI). This study can be concluded that administration of Plantago major L extract able to inhibit overexpression of Regenerating 1 gene by dose 100mg/200gbw rat/day, to increase Caspase 3 level by dose 200mg/200gbw rat/day but can not to inhibit histopathologic alteration of gastric mucosal tissues by using all of the doses.

Dealing with cases of people who became addictive will be difficult thing to handle. This because at addictive stage, the user has used to consumsed drug in large amount that makes them easely to relapse. This type of user is characterized by compulsive urge to search and using a substance even though they knows that it has dangerous consequences. This study focus to this kind of drug user with adolescent age. Early research showed that adolescents were vulnerable age to start taking drugs. Nearly 97% of cases of drug abuse starts at the age of 13-17 years ol. In general, adolescent are trial error age in situational concerning drugs. The expectation to prevent they continue using drug is still large. The aim of this study is to prove the effect of islamic religious commitment in Muslim teenagers on self-concept and self-regulation. The dimensions of islamic religious commitment consist of iman (religious belief), islam (religious practic) and ihsan (religious effect). The objective of this study is finding empirical data about effect of islamic religious commitment's dimensions to self-concept and self-regulation directly or indirectly through self concept of adolescent in Bandung. The reseach design is using causal-comparative research or ex post facto's research. Methods to collectdata was use the techniques in the form of self-report questionnaire, used ordinal scale model. This techniques is used to measure religious commitment from three basic islamic teaching and self regulation from Zimmerman's theory. To gather the data of self-concept, research is used TSCS (Tennessee Self Concept Scale), a standard measured tool developed by William Fitts. The subjects of this study consisted of 452 high school students in Bandung city. This subject gathers with stratified cluster random sampling technique. The data has been processed by approaches of Structural Equation Model (SEM) that calculated with Lisrel's program. Results of this study proved that the dimension of Iman, Islam and Ihsan as a major dimension of Islamic religious commitment that could directly effect self-concept and self-regulation and provide a greater influence on the self-regulation if it is through the self concept. Ihsan dimension is the dimension that contribute most to the Islamic religious commitment and provide greater effect of self-concept and self-regulation of adolescents.Keywords: Dimensions of iman, islam and ihsan, Islamic religious commitment, self-concept and self- regulation.

Nowadays there are various rural financial institutions (RFI), but unfortunately farmers and agribusiness SMEs are still face lackof capital. In general, risk averse attitudes among RFIs upon agricultural and rural sectors were still dominant, so intermediaryfunction of RFI was not running well. The research was conducted in West Java with at macro level using panel regression analysis and at micro level using the SEM. The results at the macro level show that RFI intermediation function was affected by DPK, NPL and the SBI. Amount of credit disburse reduce poverty level. So that poverty in West Java was difficult to be reduce as long as intermediary role of RFI was not well function. On the micro level the intermediary function reflected on the quality of service which turns a positive effect on business performance and sustainability of farmers and agribusiness SMEs.
