Abstract

Erupsi Gunung Merapi pada akhir tahun 2010 telah mengakibatkan kerusakan ekosistem terutama di wilayah Taman Nasional Gunung Merapi (TNGM). TNGM melakukan restorasi pasca letusan dengan membuat demonstrasi plot (demplot) restorasi menggunakan jenis tanaman puspa (Schima wallichii), salam (Syzygium polyanthum), dan gayam (Inocarpus edulis) sebagai tanaman inti restorasi. Di saat yang sama, jenis asing Acacia deccurens yang muncul sejak erupsi tahun 2006 mendominasi dan merubah struktur serta komposisi jenis yang ada di kawasan pasca erupsi tahun 2010. Keberadaan A. decurrens yang melimpah dalam demplot diperkirakan mengganggu pertumbuhan tanaman inti restorasi terutama dari penutupan tajuknya. Penelitian ini bertujuan mengetahui karakteristik pertumbuhan riap pohon A. decurrens pasca erupsi dan pengaruh naungan tajuk A. decurrens terhadap laju pertumbuhan tanaman restorasi. Demplot dalam penelitian ini menggunakan Rancangan Blok Tidak Lengkap (Incomplete Block Design) dengan total sembilan blok dan masing-masing blok terdiri tiga plot tanaman berbeda, sedang jarak tanam dibuat 4 m x 5 m. Data yang diambil ialah diameter A. decurrens pada berbagai kriteria diameter untuk memperoleh riap pertumbuhan. Data lain yang diukur adalah tinggi dan diameter tanaman restorasipada kondisi ternaung >60% dan tidak ternaung <60%. Data yang diperoleh dianalisis R-statistik menggunakan Wilcoxon-paired test untuk mengetahui pengaruh naungan A. decurrens terhadap pertumbuhan tanaman restorasi. Hasil pengukuran dan analisis menunjukkan bahwa riap rata-rata diameter A. decurrens di dalam demplot sebesar 1,66 cm/tahun. Pada kelas diameter pohon <3,00 cm dan >10,00 cm mengalami perubahan yang cepat dibanding kelas diameter yang lain. Analisis wilcoxon-paired test menunjukkan bahwa tanaman gayam pada pertumbuhan tinggi dan diameter dipengaruhi oleh kondisi naungan. Jenis puspa pertambahan tinggi tidak dipengaruhi oleh kondisi naungan, sedangkan pada pertambahan diameter kondisi naungan memiliki pengaruh. Jenis salam pada kondisi naungan >60% maupun <60% tidak berpengaruh terhadap pertambahan tinggi maupun diameter jenis salam

Abstract

Irrigation was an important component of the agricultural development in Indonesia, but it had many problems. Irrigation management was inefficient, irrigation networks were damaged and farmers participation were poor. These problems were caused by poor of intangible assets. The research aimed at developing the concept and the model of controlling intangible assets in irrigation system management. The research method consisted of two stages. The first stage was developing the concept. The concept of controlling intangible assets in irrigation system management was developed based on principles of knowledge management. The concept stated that intangible assets in irrigation system can be controlled using knowledge management. The second stage was developing the model which consisted of model building and sensivity analysis. Model of controlling intangible assets in irrigation system management was build using neuro-fuzzy. The model had three submodels: knowledge management, intangible assets and performance of irrigation system. Evaluating the model was done in Sapon irrigation system in Kulon Progo, Yogyakarta. Data collecting was done using questionnaire on nine Water Use Associations. Data analysis was done using Adaptive Neuro Fuzzy Inference System. The model had been evaluated using correlation coefficient, Mean Absolute Percentage Error and Root Mean Square Error. Result of the study indicated that the concept of controlling intangible assets in irrigation system management had developed based on knowledge management. The concept stated that irrigation system management had to balance between tangible assets and intangible assets. Intangible assets which had amortization need be controlled. Controlling intangible assets can be done by knowledge management. The model of controlling intangible assets in irrigation system management could predict intangible assets and performance of irrigation system well. The model linked knowledge management, intangible assets and performance of irrigation system.  Knowledge management felt into four main components: learning organization, principle of organization, policy and strategy of organization and information and communication technology which controlling intangible assets in irrigation system. Intangible assets consisted of moral intelligence, emotional intelligence, creative attitude, institutional culture, and farmer participation which  controlling effectiveness of irrigation system. Learning organization was the most sensitive parameter in influencing moral intelligence and creative attitute.  Policy and strategy were the most sensitive parameter in influencing emotional intelligence, institutional cultura and farmer participation. Farmer participation was the most sensitive parameter in influencing effectiveness of irrigation system.ABSTRAKIrigasi merupakan komponen penting dalam pembangunan sektor pertanian di Indonesia namun masih mempunyai banyak permasalahan. Manajemen irigasi belum efisien, partisipasi petani yang menurun, jaringan irigasi yang rusak sehingga menurunkan kinerja sistem irigasi. Permasalahan tersebut disebabkan rendahnya kualitas aset nirwujud sistem irigasi. Tujuan penelitian adalah mengembangkan konsep dan model pengendalian aset nirwujud dalam manajemen sistem irigasi. Metode penelitian terdiri dari dua tahap. Tahap pertama adalah pengembangan konsep. Konsep pengendalian aset nirwujud dalam manajemen sistem irigasi dikembangkan dari prinsip manajemen pengetahuan. Tahap kedua adalah pengembangkan model yang terdiri dari pembangunan model dan analisis sensitivitas. Pembangunan model pengendalian aset nirwujud dalam manajemen sistem irigasi berbasis manajemen pengetahuan dengan prinsip neuro-fuzzy. Model mempunyai tiga submodel yaitu manajemen pengetahuan, aset nirwujud dan kinerja sistem irigasi. Pengujian model dilakukan di Daerah  Irigasi Sapon di Kabupaten Kulon Progo, Propinsi Daerah Istimewa Yogyakarta. Pengumpulan data dilakukan dengan kuesioner terhadap sembilan Perkumpulan Petani Pemakai Air. Analisa data dilakukan dengan   Adaptive Neuro Fuzzy Inference System. Model dievaluasi dengan koefisien korelasi, Mean Absolute Percentage Error dan Root Mean Square Error. Penelitian menghasilkan bahwa konsep pengendalian aset nirwujud dalam manajemen sistem irigasi telah tersusun berbasis manajemen pengetahuan. Konsep menekankan bahwa manajemen sistem irigasi harus menyeimbangkan antara aset wujud dengan aset nirwujud. Aset nirwujud yang selama ini kurang diperhatikan mengalami penyusutan sehingga perlu dikendalikan. Upaya pengendalian aset nirwujud dilakukan dengan manajemen pengetahuan. Model pengendalian aset nirwujud dalam manajemen sistem irigasi yang menggunakan prinsip neuro-fuzzy dapat memprediksi aset nirwujud dan efektivitas sistem irigasi dengan cukup memadai. Model menghubungkan manajemen pengetahuan, aset nirwujud dan kinerja sistem irigasi.  Manajemen pengetahuan yang terdiri dari organisasi pembelajar, prinsip organisasi, kebijakan dan strategi organisasi, teknologi informasi dan komunikasi mempengaruhi aset nirwujud sistem irigasi. Aset nirwujud yang terdiri dari kecerdasan moral, kecerdasan emosional, sikap kreatif, budaya lembaga, dan partisipasi petani mempengaruhi efektivitas sistem irigasi. Organisasi pembelajar merupakan parameter yang paling sensitif dalam mempengaruhi kecerdasan moral dan sikap kreatif.  Kebijakan dan strategi merupakan parameter yang paling sensitif dalam mempengaruhi kecerdasan emosional, budaya lembaga dan partisipasi petani. Partisipasi petani merupakan parameter yang paling sensitif dalam mempengaruhi efektivitas sistem irigasi.

Abstract

Satonda Island Lake is a tourist attraction that attracts many tourists, both local and foreign tourists, and has abundant biodiversity in the form of flora and fauna. However, the management of the area has not been carried out optimally, both in terms of facilities and infrastructure and the involvement of the local government and community in its management. The purpose of this study was to find out the strategy for developing ecotourism on Satonda Island Lake. Data through field observations, documentation, questionnaires, and interviews to obtain data related to the potential of ODTWA (Nature Tourism Attraction Objects), tourist facilities and infrastructure, as well as public perceptions and interests of visitors. Data were analyzed through SWOT analysis to determine the strategy for developing ecotourism on Satonda Island Lake. The results of the SWOT analysis show that the development of Satonda Island Lake ecotourism is prioritized using SO (strength and opportunities) strategies with the consideration that ecotourism resources have considerable potential, but have not been utilized optimally.

Abstract

Forest fires often occur in many islands of indonesia including in Kalimantan, Sumatra, Java, Sulawesi and other regions. These fires can lead to damage for ecosystems, flora and fauna, even ecosystem hydrology. One of the hydrological system that was disturbed is the interception and infiltration. Interception is the ability of trees to retain water rain then rereleased in steam. Infiltration is the process of water absorbing into the soil, infiltration capacity is the soil’s ability of absorbing water per unit of time. This research is to know the rest of the tree's ability to retain water, and knowing the infiltration of ex forest fire area on TAHURA R. Soerjo, Ledug blocks. This research was carried out on 17-23 January 2019 in ex forest fire area on TAHURA R. Soerjo, with an elevation of 1100-1200 masl. In the ex forest fire area there are 2 dominant trees species to do measurements of interception, there are Tutup (Mallotus paniculatus) and Klerek (Sapindus rarak DC). The results of the interception on Klerek tree is 10% and Tutup is 60%.  For the capacity of the infiltration is 27, 6 mm/hour.

Abstract

Abstraction       This research was conducted on 10 November 2018 - 31 January 2019 in Ngancar Village, Ngancar District, Kediri Regency. The study was intended to determine the level of income of LMDH "Current Jaya" members in Ngancar Village. In addition, to find out the factors that influence the success of the Forest Village Society Institute (LMDH) program that has been carried out in increasing the income of members of farmer groups. The location of Ngancar Village is due to the fact that the area is one of the tourist areas which has a relatively large number of poor people.       Methods of data collection in the form of primary data collected by direct observation techniques in the field with interviews, questionnaires, and documentation studies of respondents (farmer group members) obtained by purposive sampling method. Secondary data is collected by the technique of recording data that already exists in related institutions. The data obtained will be processed by calculation and tabulation. While in the method of data analysis, researchers used two ways, namely an analysis of economic success (income), and the success factor of LMDH. For data processing methods, the income questionnaire uses the farm income formula (π) which is the difference between total receipt (TR) and total cost (TC), while the questionnaire success factor LMDH uses a Likert Scale.       Based on the results of the research conducted, Chili (Capsicum annum L) commodity was obtained 68 respondents with a total income of Rp. 3,337,850,000, with an average income per hectare of Rp. 49,086,030 in one planting season. While the commodity Tomato (Solanum lycopersicum L) obtained 47 respondents with a total income of Rp. 1,368,899,000, with an average income per hectare of Rp. 29,125,510 in one planting season.Keywords: income, factor, LMDH

Abstract

Kebakaran merupakan penyebab kerusakan hutan yang paling besar, yang mana dalam waktu singkat dapat menghancurkan kawasan yang cukup luas. Kebakaran hutan ternyata lebih banyak menimbulkan dampak negatif daripada dampak positif terhadap sifat-sifat tanah dan terutama terhadap erosi. Penelitian ini dilaksanakan untuk mengetahui besarnya sedimentasi, dan mengetahui hubungan antara curah hujan dengan sedimentasi yang terjadi pada kawasan bekas kebakaran hutan TAHURA R.Soerjo Blok Ledug. Penelitian ini dilaksanakan pada bulan Desember 2018 di Kawasan bekas kebakaran hutan TAHURA R.Soerjo, dengan estimasi ketinggian 1100-1200 mdpl. Terdapat 13 kejadian hujan pada bulan Desember 2018. Curah hujan tertinggi 68,2mm, dan curah hujan terrendah 2,5mm. Nilai muatan sedimen terbesar yaitu 0,94 kg/ha, serta nilai muatan sedimen terkecil yaitu 0,29 kg/ha, dan nilai muatan sedimen rata-ratanya yaitu 0,48 kg/ha rendahnya nilai sedimen yang didapatkan dipengaruhi oleh baiknya kualitas tanah pada lahan tersebut, dan juga dipengaruhi oleh keadaan vegetasi yang rapat dan di dominasi oleh ilalang.

Abstract

The Ledug Block is one of the areas in TAHURA R Soerjo which is experiencing fire. The fire causes the existing land cover to change or decrease, with the reduced land cover, the land will be easily exposed to surface runoff. This study aims to calculate the erosion rate in the TAHURA R Soerjo Ledug Block using the USLE equation, visual presentation of erosion using the Goegraphic Information System (GIS). This research was conducted in December 2018 in the rehabilitation area of Tahura R Soerjo Priug Ledug Block, Pasuruan. The method used is the Geographic Information System (GIS) whose data is sourced from calculations with the USLE method. The results of the study are the rain erosivity index (R) obtained from the month rainfall in 2018. The soil at the study site in each SUL is dusty clay. The vegetation in the research location in each SUL is in the form of bushes and added to SUL 3 there are several trees. The average erosion rate is 0.034 tons / ha / year. Erosion hazard classes that occur at the research location are included in class I (very mild). Enriching the land cover by planting trees with tree stands needs to be done so that the land is tightly closed and better withstand surface runoff.
