Impact of cavity extraction fans on thermal and energy performance of existing UK hotel
Authors: Rotimi Abdulazeez , Bahadori-Jahromi Ali , Mylona Anastasia , Godfrey Paulina , Cook Darren
Published: October 2017

The advantages of double-skin facade (DSF) systems, ranging between their aesthetic architectural benefits, acoustic benefits and ability to decrease the heating demand of the internal environment, have increased their popularity in Europe since the mid-1980s. However, appropriate consideration must be accorded to their design to ensure that their possible advantages are not negated. This work evaluates how the effect of extraction fans installed in the cavity of the DSF adjoining a central atrium impacts the thermal condition of the atrium and, consequently, the overall energy consumption of an existing UK hotel building. The results of the investigation demonstrated that the DSF extraction fans improve the internal temperature and condition of the adjacent central atrium, particularly in the summer. The fans result in a marginal increase in the overall energy consumption when operated throughout the year; hence, the optimum schedule for the operation of the extraction fans is during the cooling-dominant period.
Estimation of saturation flow under heterogeneous traffic conditions
Authors: Preethi Prathapan , Ashalatha Rajamma
Published: October 2017

Realistic estimation of saturation flow in passenger car units (PCU) is a challenging task for traffic engineers in developing countries. This paper introduces a new methodology for the determination of saturation flow in PCU/h under heterogeneous traffic conditions based on the area occupancy (AO) concept. AO is the proportion of time a set of observed vehicles occupies an observation region on a chosen stretch of a roadway. Traffic data collected from seven signalised intersections were analysed to determine AO and the equivalent number of standard car spaces (Ncs). Saturation flow in PCU/h was then estimated based on the Ncs. For easy and quick estimation of the saturation flow in PCU/h from the observed saturation flow in vehicles per hour, the occupancy conversion factor (OCF) is introduced. A multiple linear regression equation is proposed for prediction of the OCF. The proposed model is expected to circumvent the difficulties in the estimation of saturation flow adopting individual values of PCU. The results show that an increase in the compositional share of vehicles larger than a standard car increases the OCF while an increase in the percentage of two- and three- wheelers decreases the OCF.

Goods and Services Tax (GST): A Comparative Study of Select ASEAN Countries
Authors: Gupta Surbhi
Published: October 2017

After a decade long struggle, overcoming all the issues acting as roadblocks in its implementation, Goods and Services Tax (GST) has finally been implemented in federal India from 1July 2017. By subsuming majority of indirect taxes and cesses levied at the central and state government levels it has simplified the indirect tax regime in India and has put an end to the complex and cascading nature of the multiple tier indirect taxation. GST has already been implemented by more than 160 countries around the world. Hence it carries rich history of successes and failures. In India, both policy makers and public have a lot of expectations from the GST in terms of resolving loopholes in the pre-existing indirect tax structure. In this context, this paper attempts to study the functioning of VAT/GST of 6 ASEAN countries - Philippines, Indonesia, Singapore, Vietnam, Thailand and Malaysia - and compare it with the Indian GST regime. An attempt has also been made to draw lessons for India from the experience of these countries. India should learn from the pitfalls in administration and application of law in developing countries as well as from the successful administrative strategies of the developed countries like Singapore.

Published: October 2017

It was conducted a literature review on the relationship between masculinities and emotions, both understood as social constructs that respond to particular contexts. The principal aim is to describe the scientific production considering some parameters proposed by bibliometric studies. A comprehensive search of articles based on the definition of specific keywords and criteria according to a wide variety of databases of full text documents. The results of the systematization review show a very slow growth of these studies since the year 2000. More than a half of the studies were carried out in only two countries. There is a predominance of qualitative approach, particularly theoretical methods, such as ethnography, grounded theory and social constructionism. From the topics discussed in each of the studies, we propose a categorization to describe them and discuss implications of the emotions in the configuration of masculinities.

Introduction. Inferential reasoning (IR) is a major component of intelligence, which comprises many different cognitive processes such as perception, memory, and logic. Many studies have proposed that socioeconomic status (SES) has a negligible association with IR, but more recent findings suggest that they may have a higher association when evaluating group instead of individual SES. Objective. The aim of this study is to test the effects of both individual (students) and group (schools) socioeconomic status on IR, comparing different countries of Latin America. Method. The sample was composed of 2 358 students aged 14 and 15 years from 52 different schools (44% public) of five Latin American countries (Argentina, Brazil, Chile, Colombia, and Peru). Participants took part in an inferential reasoning test and answered a socioeconomic questionnaire. Results. SES student showed a small positive correlation with IR (r = .10, p < .001), while SES school had a more pronounced effect on IR (F [2, 1944] = 74.68, p < .001, ηp2 = .07), with higher IR at schools with higher SES. A significant difference of IR between countries (F [4, 1976] = 20.68, p < .001, ηp2 = .04), was also found with Peru showing the highest mean. Peru was the country with the higher percentage of private schools in the present study. A multilevel model was fitted using individual and group SES as predictors. Discussion and conclusion. Our findings showed that group SES have a higher predictive value of IR when compared to individual SES. This result suggests that individuals with low SES can benefit from studying on higher SES schools. Future research and the importance of public policies are discussed.

Introduction. Non-suicidal self-injuries (NSSI) are a worldwide health problem that affects principally young people, and can impact negatively the mental and physical health of those that self-injure. Objective. To examine the frequency of NSSI in 564 undergraduate students (132 male, 432 female) from Mexico City and the association of NSSI with depressive symptoms, anxiety, impulsivity, self-efficacy, and emotion regulation. Method. A convenience sample of 564 undergraduate students (aged 17-26 years) from eight universities in the Mexico City metropolitan area completed a survey in their classrooms. Results. Of the total sample, 30.9% had experimented at some point in their lifetime with NSSI on one to four occasions, while 26.9% had recurrent NSSI (i.e., five or more occasions). Nearly eleven percent self-injured in the prior 12 months. The NSSI most often reported among those who self-injured was cutting oneself (48.0%). Recurrent self-injurers reported higher levels of depression and impulsivity, and less self-efficacy than those who had experimented with such behaviors or without any lifetime NSSI. While 54.4% perceived the need for professional help, only 18.1% sought professional services. Discussion and conclusion. NSSI is a hidden problem in the college population in Mexico City which needs to be addressed by university administrators and mental health professionals. Depressive symptomatology, impulsivity, and self-efficacy are factors that should be considered when developing preventive intervention strategies.

Introduction. Teenage pregnancy is a national health priority. Having to deal with pregnancy during adolescence can cause the mother, at an already vulnerable age, to doubt her maternal capacity to cope with a challenge of this magnitude. The teenage mother’s assessment of her maternal self-efficacy is associated with her performance, in other words, the way she relates and responds to the needs of her infant, which has major implications for the latter’s development. Objective. To study the association between personal (depressive symptoms, self-esteem) and environmental characteristics (social support, partner satisfaction) and those of the infant (problems with infant care, the infants’s temperament) and the perception of maternal self-efficacy (PME) in adolescent mothers. Method. Cross-sectional study. The following instruments were applied: Center for Epidemiologic Studies Depression Scale (CES-D), Post-partum Depression Predictors Inventory-Revised (PDPI-R), and Maternal Efficacy Questionnaire to 120 mothers under 20 during the first six months postpartum. Bivariate lineal regression and hierarchical linear regression analyses were used for the data analysis. Results. When adjusting for other variables, symptoms of depression and difficult infant temperament were associated with lower PME. Social support was only associated with increased PME in the bivariate analysis. Discussion and conclusion. These findings contribute to the limited literature on the subject and provide elements for designing strategies to improve adolescent mothers’ PME to encourage behaviors that are more relevant and sensitive to infants’ physical and emotional needs.

Published: October 2017

Aberrant accumulation of a specific sialic acid has been shown to exist in many human malignant cell membranes termed as N-glycolyl neuraminic acid (NeuGc). This particular ganglioside do not normally exist in normal human cells, due to the lack of an enzyme (cytidine monophospho-N-acetyl-neuraminic acid) which is responsible for the synthesis of N—glycolyl neurominic acid. The aberrant expression of NeuGcGM3 ganglioside in the cell surface of certain human tumors, made this molecule an attractive target for immunotherapy. By using 14 F7 monoclonal antibody directed to identify NeuGcGM3 in the tumor tissue, it is possible to select patients for anti-NeuGcGM3 immunotherapy. Racotumomab is an anti-idiotype vaccine, being a mirror image of NeuGcGm3 mimics this ganglioside and triggers an immune response. Antibodies reactive to NeuGcGM3 ganglioside in the vaccinated patient’s sera have cytotoxic anti-tumor properties which can be assessed in L1210 cell line, expressing this ganglioside.

In this study, we monitored 12 patients with advanced non-small cell lung cancer (NSCLC) who are on racotumomab vaccine maintenance following chemotherapy. Cytotoxic tests with vaccinated patients’ sera were performed using L1210 cell lines at the 3rd, 6th, 9th, and 12th months of vaccination and the results were compared with clinical outcomes. Serum antibodies to NeuGcGm3 ganglioside were also checked before initiation and thereafter with the same intervals. The aim of the study was to investigate the value of antibodies and cytotoxic test as biomarkers for treatment outcome. Our observation confirmed that consistently higher cytotoxicity rates in the cell culture correlated with better progression free survivals of the patients who are on racotumomab maintenance.

Published: October 2017

В данной статье рассматриваются характеристики, достоинства и недостатки, различия и сходства электронной и традиционной розничной торговли. Установлено,что основными достоинствами электронной розничной торговли является сокращение времени на приобретение товара, так как не требуется посещение магазина, поиски необходимого товара в торговом зале, а также снижение издержек обращения. В свою очередь, это позволяет Интернет - магазину снизить цены. Недостатком электронной торговли и одновременно достоинством традиционной торговли служит то, что оплаченный товар приобретатель получает только через некоторое время, иногда даже довольно большое, а традиционных магазинах - сразу после его оплаты.
Communication Strategy on Family Planning Campaign by the Field Officer for Family Planning Campaign in North Sumatera
Authors: Andriani Lubis Lusiana , Wijaya Haris
Published: October 2017

Communication strategy on family planning campaign is the interpretation of knowledge, attitude and practice theory (KAP theory) that commonly used in many health campaign programs in developing countries and advanced countries in the world. This theory can also be applied to other programs such as agriculture, family planning, commercial, and society capacity building. The aims of this research are to describe and analyse communication strategy on family planning campaign by the field officer, and also to find out all factors that can be the obstacle on family planning program in Sumatera Utara province, especially in Sibolga City. The long-term goal of this research is to find out the best method that can be done by the government in order to get people’s support. It can only be achieved if the program is transparent, clearly stated and on the perfect target. The population of the research are the field officer for family planning campaign (10 persons) and also the citizen of Sibolga City (10 persons plus their husband/wife). Purposive sampling technique was selecting all informants. Observation, interview and Focus Group Discussion were also being held in order to get the best result. Several results were shown: it showed (especially using injection and implant method) among productive age couples is increasing. Nias people in Sibolga City are the most fragile community where many of them are not able to perform family planning due to lack of information because of the language problem. Another problem in Sibolga City is that many of the family planning acceptors using short-term contraception methods such as pill, condom and injection rather than long-term contraception methods such as IUD, implant or vasectomy/tubectomy. BKKBN in Sibolga City still needs to improve many aspects of doing communication strategy on family planning campaign by the field officer for family planning campaign, especially in the low-income productive age couples where the birth rate number is still high.

Idealizado e parcialmente executado pelo afamado engenheiro-urbanista Francisco Prestes Maia, o Plano de Melhoramentos Urbanos mudou profundamente as feições urbanas da cidade de Campinas, imprimindo no imaginário social e político da cidade certa concepção de planejamento urbano associada à racionalidade, ao progresso e à modernidade, marcas então tomadas como incontesti da pujança econômica e do papel de destaque que a cidade assumiria no cenário da economia paulista.
Revealing ETC-1922159 Affected Unknown 3rd order WNT10B-X-X Combinations, in Silico
Authors: sinha shriprakash
Published: October 2017

WNT10B belongs to the family of WNT proteins that are implicated in a range of phenomena that are affected by the Wnt signaling pathway. Recent studies have shown that WNT10B plays a role in colorectal cancer. WNTs have been found to directly affect the stemness of the tumor cells via regulation of ASCL2. Switching off the ASCL2 literally blocks the stemness process of the tumor cells and vice versa. Furthermore, recent findings suggest BVES to be highly suppressed in malignancies and in vitro deletions of BVES show higher Wnt signaling activity to induce stem- ness. WNT10B was found to be highly expressed in such cases. Often, in biology, we are faced with the problem of exploring relevant unknown biological hypotheses in the form of myriads of combination of factors that might be affecting the pathway under certain conditions. For example, WNT10B-ASCL2 is one such 2nd order combination whose relation needs to be tested under the influence of recently developed porcupine-WNT inhibitor ETC-1922159. The inhibitor is known to suppress PORCN (porcupine) and thus inhibit a range of oncogenes known to be directly or indirectly affected by the Wnts. In a recent unpublished work in bioRxiv, Sinha 1, we had the opportunity to rank these unknown biological hypotheses for down regulated genes at 2nd order level after the drug was administered. The in silico observations showed that the combination of WNT10B-ASCL2 was assigned a relatively lower rank, thus validating the pipeline’s efficacy with the confirmed wet lab experiment that indicate that both WNT10B and ASCL2 were down regulated after treatment in cancer cells. Here, we take one step further by in silico analysis of the 3rd order combinations of WNT10B-X-X (X can be known or unknown factor), from a range of 100 randomly picked down regulated genes after ETC-1922159 treatment. The pipeline uses the density based HSIC (Hilbert Schmidt Information Criterion) sensitivity index with an rbf (ra- dial basis function) kernel, which is known to be highly effective in sensitivity analysis. Various unknown/unexplored/untested 3rd order biological hypotheses emerge some of which are con- firmed in wet lab, while others need to be tested. The potential of such ranking is indispensable in the current era of search in a vast combinatorial forest.

Published: October 2017

We perform an extensive comparison between 11 stochastic to 9 machine learning methods regarding their multi-step ahead forecasting properties by conducting 12 large-scale computational experiments. Each of these experiments uses 2 000 time series generated by linear stationary stochastic processes. We conduct each simulation experiment twice; the first time using time series of 110 values and the second time using time series of 310 values. Additionally, we conduct 92 real-world case studies using mean monthly time series of streamflow and particularly focus on one of them to reinforce the findings and highlight important facts. We quantify the performance of the methods using 18 metrics. The results indicate that the machine learning methods do not differ dramatically from the stochastic, while none of the methods under comparison is uniformly better or worse than the rest. However, there are methods that are regularly better or worse than others according to specific metrics.
A Rapid Screening Test for the Diagnosis of Influenza Infection Incubation Period Using Coincidence Analysis of Pulse Waves
Authors: Chen Po-Ying , Tu Keng-Chang , Yu Shyr-Shen , Yeh Wen-Kuan
Published: October 2017

Viral infections have long been the biggest threat to human survival, and from a medical perspective, the development of noninvasive high-throughput screening methods that target the incubation period to either treat diseases or limit viral spread would be strikingly effective. Using this technology to target viral incubation periods would also be inexpensive to perform. The current study proposes to transform pulse signals into a rapid diagnostic test using “coincidence analysis” in the hope of preventing or reducing the symptoms of viral infections. The heart plays a critical role in calculating and supplying the needs of all tissues of the body. Pulse waves are pressurized signals in response to heart’s calculations and include all phases of the cardiac cycle, which maintains life and provides energy needed to perform tasks. Any small movement gives a corresponding signal to pulse waves. The current study investigated conclusive data on self-limiting infections, such as common cold. We used pulse wave, coincidence analysis technology to capture signals from individuals with common cold during the incubation period and investigated if particular characteristic signals could be applied to influenza during the incubation period. Preliminary work demonstrated that pulse waves could generate signals using this technology that would be worthwhile for future research. A small amount of analytical data from common cold existed previously. The data structure is based on the idea that a single pulse wave at differing physiological conditions would have slight modifications that would be amplified and presented by various geometrical shapes after extensive data are accumulated. These geometric shapes can then be sliced vertically or horizontally to extract data during different illness stages. The significance of these findings are impressive; from a personal or a public hygiene perspective, this analytical technology provides many benefits, such as rapid and precise decision-making that can be directly visualized or can be analyzed using software programs. Also, this technology also uses futuristic wearable technology that brings practical problem solving to physiology.
A Case Study on Large Deformation Failure Mechanism of Coal given Chamber and Invention of a New Wall-Mounted Coal Bunker in Xiashijie Coal Mine with Soft, Swelling Floor Rock
Authors: Wang Xingkai , Xie Wenbing , Jing Shengguo , Bai Jianbiao , Su Zhili
Published: October 2017

Serious damage caused by floor heave in the coal given chamber of a vertical coal bunker is one of the challenges faced in underground coal mines. Engineering practice shows that it is more difficult to maintain the coal given chamber (CGC) than a roadway. More importantly, repairing the CGC during mining practice will pose major safety risks and reduce production. Based on the case of the serious collapse that occurred in the bearing structure of the CGC at the lower part of the 214# coal bunker in Xiashijie mine, China, this work analysed (i) the main factors influencing floor heave and (ii) the failure mechanism of the load-bearing structure in the CGC using FLAC2D numerical models and expansion experiment. The analysis results indicate that: the floor heave, caused mainly by mine water, is the basic reason leading to the instability and repeated failure of the CGC in the 214# coal bunker. Then a new coal bunker, without building the CGC, is proposed and put into practice to replace the 214# coal bunker. The FLAC3D software program is adopted to establish the numerical model of the wall-mounted coal bunker (WMCB), and the stability of the rock surrounding the WMCB is simulated and analysed. The results show that: (1) the rock surrounding the sandstone segment is basically stable. (2) The surrounding rock in the coal seam segment, which moves into the inside of the bunker, is the main zone of deformation for the entire rock mass surrounding the bunker. Then the surrounding rock is controlled effectively by means of high-strength bolt–cable combined supporting technology. According to the geological conditions of the WMCB, the self-bearing system, which includes (i) H-steel beams, (ii) H-steel brackets, and (iii) self-locking anchor cables, is established and serves as a substitute for the CGC to transfer the whole weight of the bunker to stable surrounding rock. The stability of the new coal bunker has been verified by field testing, and the coal mine has gained economic benefit to a value of 158.026174 million RMB over three years. The new WMCB thus made production more effective and can provide helpful references for construction of vertical bunkers under similar geological conditions.
Bayesian Analysis of Competing Risks Models with Masked Causes of Failure and Incomplete Failure Times
Authors: Yousif Yosra , Elfaki Faiz A. M. , Hrairi Meftah
Published: October 2017

Bayesian analysis for masked data under competing risk frameworks is studied for the purpose of assessing the impact of covariates on the hazard functions when the failure time is exactly observed for some subjects but only known to lie in an interval of time for the remaining subjects. Such data, known as partly interval-censored data, usually result from periodic inspection. Dirichlet and Gamma processes are assumed as priors for masking probabilities and baseline hazards. The Markov Chain Monte Carlo (MCMC) technique is employed for the implementation of the Bayesian approach. The effectiveness of the proposed model is tested through numerical studies, including simulated and real data sets.

Indonesian
Kelompok rumah tangga adalah sasaran utama dalam program peningkatan dan perbaikan tingkat konsumsi pangan dan gizi. Oleh karena itu, keberhasilan program ini ditentukan oleh kemampuan mengidentifikasi rumah tangga yang menjadi sasaran tersebut. Penelitian ini mencoba mengidentifikasi ciri-ciri rumah tangga defisit energi pada berbagai tipe agro-ekosistem di pedesaan Jawa Tengah. Penentuan rumah tangga defisit energi dihitung dengan cara membandingkan kebutuhan energi suatu rumah tangga terhadap tingkat konsumsinya. Apabila tingkat konsumsi kurang dari 70 persen dari energi yang dibutuhkannya, maka rumah tangga tersebut dikelompokkan pada kelompok defisit energi. Hasil penelitian menunjukkan bahwa ciri-ciri rumah tangga defisit energi adalah: (a) Adanya perbedaan tingkat konsumsi energi pada berbagai tipe agro-ekosistem dengan sumber energi utama padi-padian; (b) Jumlah anggota rumahtangga umumnya lebih banyak pada semua tipe agro-ekosistem; (c) Sumber pendapatan utama adalah sektor-sektor padat karya (modal dan keterampilan rendah). (d) Tingkat pendidikan kepala rumahtangga umumnya rendah; dan (e) Penguasaan dan pemilikan lahan sempit, sehingga banyak menjadi sebagai penggarap. Dalam jangka pendek implikasi dari penelitian ini, membutuhkan penyuluhan yang lebih intensif tentang konsumsi energi dan gizi, seperti melalui peningkatan pemanfaatan lahan pekarangan dan pengadaan asset-asset produktif bagi rumah tangga defisit energi di pedesaan.

As a origin institution in rural area, pesantren always involve in activities of its environment, even in economic activity. Recently, pesantren has been considered as an alternative institution as an entry point by outsider to enhance agricultural development in rural communities. Not as common people knowledge, in fact, pesantren has adaptive power to rural community changes. Eventhough one of the main objective of pesantren is Islamic education, but it is also involved in politics since colonial era. The economic vision of pesantren is rather weak, but in the daily activities they proceed quite good like establish a cooperative, retail business, and so on. Economic aspect is one important part in pesantren organization, especially at madrasyah and nonprofit organization.

Sebagai lembaga pendidikan asli Indonesia, pesantren selalu melibatkan diri dengan perubahan masyarakat disekitarnya, termasuk dalam bidang ekonomi. Akhir-akhir ini, pesantren telah dipandang sebagai lembaga alternatif yang dijadikan entry point oleh berbagai pihak ke dalam masyarakat desa, misalnya dalam bidang pembangunan pertanian. Mungkin tidak sebagaimana pengetahuan banyak orang, pesantren sebenarnya memiliki daya adaptasi yang cukup tinggi terhadap perubahan dilingkungannya. Meskipun tujuan utama lembaga pesantren adalah pada wacana pendidikan, namun secara historik terbukti ia telah ikut melibatkan diri secara intens dalam dunia lain misalnya dunia politik semenjak zaman kolonial Belanda. Dalam wacana ekonomipun pesantren memiliki visi meskipun hanya bersifat minor dalam materi pengajarannya. Sikap dan perilaku terhadap aspek ekonomi lebih berbentuk dalam tataran praktis sehari0hari. Beberapa studi terakhir mendapatkan bahwa aspek ekonomi sudah menjadi bagian yang inheren dan semakin jelas dalam struktur kehidupan pesantren, terutama pada pesantren yang berbentuk madrasyah dalam bentuk organisasi yayasan.

Dalam kontek ini, kajian yang memadukan antara pertumbuhan dan pemerataan pada industri perunggasan di pandang sangat relevan, karena pada bidang usaha ini telah terjadi ketimpangan struktur pasar input, pasar hasil (output), integrasi vertikal dan horisontal, dan tersisihnya peternakan rakyat. Kebijakan pemerintah yang bias ke pemacuan pertumbuhan ekonomi adanya dampak krisis ekonomi berkepanjangan telah berdampak buruk pada kinerja industri perunggasan

Rice Production Enhancement Programs (P4) is consistently carried out by the government to meet domestic demand for rice. This paper describes dynamics of P4 implementation, namely their strengths and weaknesses. There were 11 programs launched, beginning with Central Rice Program (Padi Sentra) in 1958 up to Special Intensification (Insus) in 1979 with highest achievement of rice self sufficiency in 1984. Insus was improved in 1987 and it was then called as Supra Insus. In 1990 rice production was stagnant and rice import tended to enlarge. Rice Based Farming System with Agribusiness Orientation (SUTPA), Agribusiness Oriented Intensification (Inbis), and Self Reliance Movement on Rice, Corn, and Soybean (Gema Palagung) programs were introduced to anticipate changing domestic and international circumstances. El Nino took place when the programs were carried out triggering delay of harvest seasons and low production. At last, paradigm of agricultural development was improved through system development and agribusiness oriented, namely corporate farming as the starting point of on-going Integrated Crops and Resources Management (PTT) program. To induce the farmers nationwide to adopt technologies immediately the government copes with many constraints. It is suggested that the generated technologies are packed in sociodrama before disseminated intensively through various mass media, especially television.

Untuk mencukupi kebutuhan beras, pemerintah terus mengupayakan program peningkatan produksi padi (P4) melalui berbagai kebijakan. Tulisan ini mengemukakan dinamika P4 yang telah diimplementasikan dengan menganalisis kelemahan dan kekuatan suatu program. Tujuan penulisan untuk memperoleh opsi kebijakan P4 mendatang. Ada sebelas program yang telah diluncurkan, diawali dengan Program Padi Sentra (1958) hingga lahir Intensivikasi Khusus (1979) yang berhasil meraih swasembada beras (1984). Tahun 1987 Insus disempurnakan menjadi Supra Insus. Tahun 1990 produksi padi cenderung stagnan, import beras terus meningkat. Untuk merespon berbagai perubahan lingkungan internasional dan domesik diimplementasikan program Sistem Usahatani Berbasis Padi Berorientasi Agribisnis (SUTPA), Intensifikasi yang Berwawasan Agribisnis (Inbis) dan Gema Palagung. Saat program dalam implementasi terjadi El-Nino yang menyebabkan panen mundur dan produksi rendah. Akhirnya dilakukan pembenahan paradigma dalam pengembangan pertanian yaitu mutlak berbasis pengembangan sistem dan berorientasi agribisnis, yaitu usahatani korporasi yang selanjutnya menjadi dasar dalam program Pengelolaan Tanaman dan Sumberdaya Terpadu (PTT) yang sedang diuji. Selalu ditemukan kendala dalam menyebarluaskan teknologi yang telah dihasilkan dalam skala luas agar cepat diadopsi petani. Diusulkan agar teknologi yang telah dihasilkan dikemas dalam sosiodrama kemudian disebarluaskan secara intensif melalui berbagai media terutama televisi.

The objective the paper is to elaborate some aspects those related to wetland conversion in Java. Although the wetland conversion data are various, it is predicted that not less than 40,000 ha per year of wetland in Java are converted to non agricultural uses. This phenomenon could threaten food security because Java is well known as the main rice producing area in Indonesia. This study shows that Java still contributes significantly to national rice production, i.e., on average more than 50 percent per year. Nevertheless, the long term wetland conversion can create a serious problem, especially in the matter of rice self sufficiency, if it is not well managed immediately. To anticipate the effects of wetland conversion, the government has implemented an area extensification program on wetland outside Java. Furthermore, the government has released many rules to protect agricultural land in Java from conversion to non agricultural uses. However, implementation those rules are not effective.

Makalah ini bertujuan melihat beberapa aspek yang berkaitan dengan alih fungsi lahan sawah di Pulau Jawa. Terjadinya alih fungsi lahan dikhawatirkan dapat mengganggu produksi pangan di Indonesia, karena selama ini Pulau Jawa menjadi andalan dalam produksi beras nasional. Diperkirakan tidak kurang dari 40.000 ha per tahun lahan sawah terkonversi ke penggunaan non sawah. Hasil studi menunjukkan bahwa Pulau Jawa masih tetap menjadi lumbung padi nasional, terbukti dari kontribusinya yang selalu lebih besar dari 50 persen. Namun, dalam jangka panjang konversi lahan sawah di Pulau Jawa dapat mengancam kecukupan pangan di Indonesia. Untuk mengantisipasinya pemerintah telah mengambil langkah dengan program pencetakan lahan sawah di luar Jawa. Di samping itu juga telah diterbitkan berbagai peraturan/perundang-undangan untuk melindungi lahan pertanian, walaupun implementasinya belum berjalan dengan efektif.

The role of agricultural sector is very important to enhance the national economic development although its development is not fully supported by sufficient capital. The existing formal financial institutions tend to prioritize non-agricultural services which have high profit but low risk. In this context, efforts to establish agricultural bank institution that especially support agricultural activity services are highly recommended. This paper aimed at a review of the urgency, possibility, potential, and constraints of agricultural bank establishment in Indonesia. The result showed that conceptually and empirically, agricultural bank institution has a promising prospective in Indonesia. There are many options in respect to agricultural bank establishment in Indonesia, such as (1) Credit-agricole “France model”, (2)  “Bank Bukopin”  model, (3) foreign direct investment model, (4) upgrading of “BUMN Bank” to “Agricultrual Bank” model, and (5) utilizing the financial institution that locally available and accessible by the people. For efficient and effective of the services, the agricultural bank should be designed based on agricultural characteristics and typical actors of agricultural business.

Peran sektor pertanian yang sangat strategis dalam perekonomian nasional belum diimbangi dengan dukungan penyediaan modal yang memadai.  Lembaga perbankan formal yang ada saat ini cenderung bias dan lebih mengutamakan pembiayaan non pertanian. Dengan memperhatikan fenomena tersebut, perlu upaya pembentukan lembaga keuangan yang khusus bergerak dalam pembiayaan sektor pertanian. Salah satu wacana tentang bentuk lembaga keuangan tersebut adalah dengan mendirikan Bank Pertanian. Tulisan ini bertujuan melakukan tinjauan mengenai urgensi, potensi dan kendala pembentukan bank pertanian di Indonesia. Hasil kajian menunjukkan bahwa secara konseptual maupun empirik, Bank Pertanian sangat prospektif untuk diwujudkan di Indonesia. Ada beberapa format Bank Pertanian yang dapat menjadi pilihan di antaranya (i) pola pendirian credit-agricole Perancis, (ii) pola pendirian bank Bukopin, (iii) investasi langsung modal asing (iv) mendorong bank BUMN menjadi bank pertanian, serta (v) memanfaatkan lembaga keuangan yang tumbuh dan berkembang di tingkat lokal. Agar Bank Pertanian dapat melayani nasabah secara efektif dan efisien, maka bank tersebut harus didesain sesuai dengan kekhasan karakteristik sektor pertanian dan pelaku usaha pertanian.
