This paper discusses the biography of K.H. Abdul Halim, a cleric, educator, political activist, a national hero, who was born in Jatiwangi, Majalengka, West Java on June 26, 1887 and died on May 7, 1962, in a peaceful and quiet place, Santi Asromo, Majalengka. The title of the National Hero from the Government of Indonesia was granted on the basis of his important roles in education, economics and politics. Among his legacy are the religious educational institutions, namely Santi Asromo Pesantren, the religious organization of the Islamic Ummah Union (PUI), and several books such as the Kitab Petunjuk bagi Sekalian Manusia (Manual for Man), Ekonomi dan Koperasi dalam Islam (Economics and Cooperative in Islam), dan Ketetapan Pengajaran di Sekolah Ibtidaiyah Persyarikatan Ulama (The Teaching Decrees at Ibtidaiyah Persyarikatan Ulama School). His biography is a manifestation of appreciation for his services and works, his struggle and his devotion to science and people, as well as his role and contribution in building the nation of Indonesia with noble character and dignity. Another milestone of his is the value of the struggle and at the same time his Islamic scholarship can be an example for the younger generation in particular and for anyone who aspires to build a nation of Indonesia which is based on the Belief in One God, fair and civilized, united in the context of the Republic of Indonesia (NKRI). Keywords: Kiai, Education, Pesantren, Majalengka, West Java Tulisan ini mengangkat biografi K.H. Abdul Halim dan gagasannya tentang pendidikan ekonomi di pesantren. Ia memiliki nama kecil Otong Syatori, dikenal sebagai ulama pejuang, pendidik, dan aktivis politik. Ia dilahirkan di Desa Ciborelang, Kecamatan Jatiwangi, Majalengka, Jawa Barat, pada 26 Juni 1887, dan wafat dalam usia 75 tahun pada 7 Mei 1962, di Santi Asromo, Majalengka. Ia mendapat gelar Pahlawan Nasional dari Pemerintah RI tahun 2008. Perjuangannya meliputi pendidikan, ekonomi, dan politik. Adapun metode yang digunakan dalam tulisan ini adalah deskriptif-analitis dengan perspektif historis. Adapun fokusnya, selain biog¬rafi singkat K.H. Abdul Halim, juga tentang konsep pendidikan eko¬no¬mi berbasis pesantren. Dari hasil pembahasan ditemukan bahwa ia telah melakukan pembaharuan di bidang pendidikan agama dan sekaligus memberikan keterampilan kewirausahaan bagi santri dan lulusannya. Awalnya gagasan tersebut berasal dari konsep pembaharuannya yang disebut Iṣlāḥ as-Ṡamāniyyah, yaitu: perbaikan akidah, ibadah, pendidikan, keluarga, kebiasaan (adat), masyarakat, ekonomi, dan hubungan umat dan tolong-menolong. Di bidang pendidikan, ia memadukan sistem pesantren dengan sistem sekolah, ilmu-ilmu agama dengan ilmu-ilmu umum, serta memberkali para santrinya dengan berbagai keterampilan tangan dan keahlian teknik. Di bidang ekonomi, disebutnya dengan Iṣlāḥ al-Iqtiṣād, untuk menanggulangi ketimpangan ekonomi di masyarakat, yaitu dengan menanamkan kesadaran kepada kaum muslimin agar berusaha memperbai¬ki dan meningkatkan kehidupan ekonominya dan berjuang secara bersama-sama melalui wadah koperasi. Kata kunci: Abdul Halim, Santi Asromo, pendidikan ekonomi, Iṣlāḥ as-Ṡamāniyyah, Iṣlāḥ al-Iqtiṣād

Forest and climate change in the inner-Alpine dry region of Visp Over the past decades, observed increases in temperature have been particularly pronounced in mountain regions. If this trend should continue in the 21st Century, frequency and intensity of droughts will increase, and will pose major challenges for forest management. Under current conditions drought-related tree mortality is already an important factor of forest ecosystems in dry inner-Alpine valleys. Here we assess the sensitivity of forest ecosystems to climate change and evaluate alternative forest management strategies in the Visp region. We integrate data from forest monitoring plots, field experiments and dynamic forests models to evaluate how the forest ecosystem services timber production, protection against natural hazards, carbon storage and biodiver-sity will be impacted. Our results suggest that at dry low elevation sites the drought tolerance of native tree species will be exceeded so that in the longer term a transition to more drought-adapted species should be considered. At medium elevations, drought and insect disturbances as by bark beetles are projected to be important for forest development, while at high elevations forests are projected to expand and grow better. All of the ecosystem services that we considered are projected to be impacted by changing forest conditions, with the specific impacts often being elevation-dependent. In the medium term, forest management that aims to increase the resilience of forests to drought can help maintain forest ecosystem services temporarily. However, our results suggest that relatively rigid management interventions are required to achieve significant effects. By using a combination of environmental monitoring, field experiments and modeling, we are able to gain insight into how forest ecosystem, and the services they provide, will respond to future changes.

Pinus heldreichii is a high-altitude coniferous tree species naturaly occurring in small and disjuncted populations in the Balkans and southern Italy. The aim of this study was to assess diversity and composition of fungal communities in living needles of P. heldreichii specifically focusing on fungal pathogens. Sampling was carried out at six different sites in Montenegro, where 2-4 year-old living needles of P. heldreichii were collected. Following DNA isolation, it was amplified using ITS2 rDNA as a marker and subjected to high-throughput sequencing. Sequencing resulted in 31,831 high quality reads, which after assembly were found to represent 375 fungal taxa. The detected fungi were 295 (78.7%) Ascomycota, 79 (21.0%) Basidiomycota and 1 (0.2%) Mortierellomycotina. The most common fungi were Lophodermium pinastri (12.5% of all high-quality sequences), L. conigenum (10.9%), Sydowia polyspora (8.8%), Cyclaneusma niveum (5.5%), Unidentified sp. 2814_1 (5.4%) and Phaeosphaeria punctiformis (4.4%). The community composition varied among different sites, but in this respect two sites at higher altitudes (harsh growing conditions) were separated from three sites at lower altitudes (milder growing conditions), suggesting that environmental conditions were among major determinants of fungal communities associated with needles of P. heldreichii. Trees on one study site were attacked by bark beetles, leading to discolouration and frequent dieback of needles, thereby strongly affecting the fungal community structure. Among all functional groups of fungi, pathogens appeared to be an important component of fungal communities in the phyllosphere of P. heldreichii, especially in those trees under strong abiotic and biotic stress.
