Pernikahan merupakan suatu kegiatan yang merubah suatu hal yang haram menjadi halal dengan syarat sah sebuah pernikahan tersebut terpenuhi, tetapi yang menjadi fenomena di indonesia, terjadinya angka pernikahan yang tinggi pada pernikahan usia muda. Hal ini dikarenakan ada sebagian pemikiran dari masyarakat bahwa menikahkan anaknnya dengan cepat maka tidak perlu lagi menafkahi anaknya tersebut, melepas tanggung jawab sebagai orang tua apabila anaknya adalah perempuan. Penelitian ini dilatarbelakangi oleh banyaknya kasus pernikahan muda yang terjadi di kalangan remaja. Pernikahan muda terjadi karena berbagai faktor, diantaranya faktor ekonomi, pergaulan bebas, maupun rendahnya tingkat pendidikan. Pernikahan muda rentan melahirkan keluarga yang miskin karena rendahnya pendidikan sehingga rendah pula akses pekerjaan yang didapat. Penelitian ini bertujuan untuk mengetahui apa saja dampak yang ditimbulkan dari pernikahan usia muda terhadap perekonomian kelurga. Metode yang digunakan dalam penelitian ini adalah metode kualitatif. Jenis penelitian ini adalah penelitian deskriptif. Subjek dalam penelitian adalah pasangan yang menikah usia dini umur 16 - 19 tahun.

Published: February 2024

This study aims to explain the opinions of ushuliyin regarding the following issues: Mukholafatur Rowi lima Rowahu (Rowi's exclusion of what is narrated) and its influence on fiqh issues. The choice of this theme is motivated by the findings of the author that sometimes Rowi's actions in a problem contradict the hadith she narrated. What is the evidence of his actions or history? And what effect will this difference of opinion have on fiqh matters? This paper includes qualitative research by conducting literature reviews of several sources from ulama's books and various papers, as well as several sources from trusted websites on the internet. From this study, the authors conclude that: 1) the selected opinion in this matter is the opinion of several ulama who say that if Rowi differs from what was narrated, his history is still used as an argument. Meanwhile, Madhab Hanafi disagreed with the opinion of the jumhur by considering that history could not be used as evidence. 2) This difference of opinion has an influence on the determination of the law in fiqh matters including in the matter of washing vessels when licked by dogs, raising hands when they want to bow and rising from them, requirements of marriage guardians, problems of divorce against slaves being sold, and problems of labanul fahl.

The water utilization in Grojogan Sewu Nature Tourism Park has been used by community around it to fulfill their water needs such as cooking and farming. In the other hand, it is presumed that they have still lack of awareness and appreciation about the conservation object. One of the efforts to increase the community awareness for the water conservation in Grojogan Sewu Nature Tourism Park is to inform the economic value of the water they use every day. This study aims to analyze the economic value of domestic water use and agricultural irrigation that has been carried out by the community around the Grojogan Sewu TWA area. The research method used in this research is quantitative and qualitative methods. The results showed that the economic value of the use of domestic water and agricultural irrigation by the community around the TWA Grojogan Sewu area was Rp238,565,600,000/month and Rp7,548,750.00/year. This result shows that the economic value of water utilization in TWA Grojogan Sewu is quite high, although the community is not aware of it. This can be illustrated by the value of the community's willingness to pay for the use of water which is still in the fairly low category, which is only Rp7,687,00/month for domestic water use and Rp6,818.00/month for the use of agricultural irrigation.

Forest fires are one of the environmental problems that recur almost every year in Indonesia. This problem if not handled properly will certainly cause various negative impacts such as the emergence of haze that can interfere with public health and reduced forest cover, in forest areas. Taman Hutan Raya Nipa-Nipa (Tahura) as one of the Natural Preservation areas of Southeast Sulawesi Province is also inseparable from the problem of forest fires. The aims of the study were to analyze the level of forest fire vulnerability in the Tahura Nipa-Nipa area, especially in Watu-Watu Village, West Kendari Subdistrict, and the variables that most affect the level of forest fire vulnerability. Data analysis based on the weighting of each element is then carried out the determination of the vulnerability class using equations: forest fire vulnerability = {30 % x (land cover)} + {(20 % x height of place)} + {(20 % x Rainfall)} + {(10 % x distance from road)} + {(10 % x distance from river)} + {(10 % x distance from settlement)}. Mapping the class of forest fire vulnerability areas using geoprocessing with input data on land cover, place height, rainfall, and distance from roads, rivers, and settlements. Then an analysis is carried out and will be selected data according to the score of the level of forest fire vulnerability, namely very low/not a vulnerability with a score of 5, low with a score of 4, medium with a score of 3, high with a score of 2, very high /very vulnerability with a score of 1. The results showed that the level of forest fire vulnerability in Tahura Nipa-Nipa has 3 levels, namely the level of high forest fire vulnerability with an area of 68.51 ha, the level of moderate forest fire vulnerability with an area of 62.29 ha, and the level of low fire vulnerability with an area of 143.35 ha. The variables that most affect the level of forest fire vulnerability at the research site are land cover and community accessibility distance in the form of distance from the road and distance from the settlement.

Published: February 2024

Indonesia is estimated to have 14,5 million hectares of karst areas. The characteristic of karst vegetation is specific, one of which is the dominance of small trees. With all of the potency, their vegetation acts as a significant carbon sequester and store it in biomass. This study aims to estimate and discuss biomass estimation in the karst forest within the Nature Recreational Park of Beriat, a protected area in South Sorong, West Papua. A total of 28 plots were made in the forest using the purposive random sampling method. Tree biomass (DBH ≥10 cm) was estimated using five different allometric equations. The results showed that the biomass was estimated at ca. 264 Mg ha-1 (95 % CI: 135-454 Mg ha-1). While small trees (DBH 10 – 30 cm) only contribute 30 % of the total biomass, about 38 % of the biomass is the contribution of large trees (DBH >50 cm), where Pometia pinnata contributes ca. 39 % of the biomass at plot-level. The use of various allometric equations results in different biomass estimates and biases with deviations ranged from -14.78 % to +17.02 % compared to the reference equation. Therefore, the selection of allometric equations used must be considered carefully to reduce uncertainties in biomass estimation.

Published: February 2024

One of state forest areas managed by three management regimes is Bunder forest area, Gunungkidul, Yogyakarta. Three management regimes are the production forest of KPH Yogyakarta, the conservation forest of Tahura, and the educational forest of KHDTK Wanagama I. The differences of management regimes are thought to affect the actual interaction pattern of villagers with the forest. This research aims to compare the actual rights and access of villagers to Bunder forest area in three management regimes in the hope of finding more effective forest management patterns. This research used a qualitative approach through the case study method of the interaction villagers of Bunder, Banaran, Ngleri, and Gading villages with the surrounding forests. The results show that forest management regimes affects the way villagers can access the forests. The aggregate value of the actual rights received by the villagers to the production forest of KPH Yogyakarta is higher than the educational forest of KHDTK Wanagama I. The lowest is management regimes in conservation forest of Tahura. Based on the access mechanisms that empower villagers, the educational forest regime of KHDTK Wanagama I is higher than the production forest regime of KPH Yogyakarta and the conservation forest regime of Tahura. This research recommends defining rights and access to increase certainty about the benefits of forest resources.

Kalapi (Kalappia celebica Kosterm.) is endemic in Sulawesi and Endangered species. Plant propagation needs to be done but is constrained by limited seeds. Vegetative propagation of plants can be an alternative method such as using the root cutting technique that has been done previously on other types of species. This study aims to determine the success of vegetative propagation of kalapi (K. celebica), an endangered tree species by root cuttings using Rootone F. as root growth regulator. The research took place from March to June 2019 conducted at the plastic house of the Indonesian Mycorrhizal Association (AMI) Southeast Sulawesi Branch, Kendari. This study used a Randomized Block Design (RBD) consisting of 6 treatments of Rootone-F concentration: (a) 0 ppm, (b) 100 ppm, (c) 200 ppm, (d) 300 ppm, (e) 400 ppm and (f) 500 ppm. Each treatment was repeated three times and three units of the plant so that the total experimental unit used was 54 units. The results showed that the provision of Rootone-F could increase the success of the growth of kalapi root cuttings. Rootone-F concentration of 500 ppm gives the best results on the percentage of cuttings, percentage of sprouts, percentage of roots, number of shoots and shoot dry weight. The results showed that kalapi can be propagated by root cuttings.

Published: February 2024

The quest for simple and practically implementable synchronization control functions is the fundamental motive for this research work because most of the control functions for synchronization are bulky thereby leading to complexity in implementation and high cost. This research paper examines the combination-combination synchronization of chaotic fractional order systems of identical order evolving from different initial conditions via the backstepping nonlinear control technique with the aim of reducing the control function’s complexity and cost. So, based on the stability theory of fractional order systems, stable synchronization are designed via a backstepping technique using chaotic fractional order Duffing and Aneodo as the paradigm. Numerical simulations are presented to confirm the feasibility of the analytical technique. The number of control functions has been sufficiently reduced compared to previous work hence reduction in control functions complexity and reduced cost of implementation. The outcome of this work may be useful to give a better understanding of the underlying dynamical behaviour among several interacting particles particularly in particle physics.

Background:Fetal growth restriction (FGR) is a pregnancy complication in which a newborn fails to achieve its growth potential, increasing the risk of perinatal morbidity and mortality. Chronic maternal gestational hypoxia, as well as placental insufficiency are associated with increased FGR incidence; however, the molecular mechanisms underlying FGR remain unknown.Methods:Pregnant mice were subjected to acute or chronic hypoxia (12.5% O2) resulting in reduced fetal weight. Placenta oxygen transport was assessed by blood oxygenation level dependent (BOLD) contrast magnetic resonance imaging (MRI). The placentae were analyzed via immunohistochemistry and in situ hybridization. Human placentae were selected from FGR and matched controls and analyzed by immunohistochemistry (IHC). Maternal and cord sera were analyzed by mass spectrometry.Results:We show that murine acute and chronic gestational hypoxia recapitulates FGR phenotype and affects placental structure and morphology. Gestational hypoxia decreased labyrinth area, increased the incidence of red blood cells (RBCs) in the labyrinth while expanding the placental spiral arteries (SpA) diameter. Hypoxic placentae exhibited higher hemoglobin-oxygen affinity compared to the control. Placental abundance of Bisphosphoglycerate mutase (BPGM) was upregulated in the syncytiotrophoblast and spiral artery trophoblast cells (SpA TGCs) in the murine gestational hypoxia groups compared to the control. Hif1α levels were higher in the acute hypoxia group compared to the control. In contrast, human FGR placentae exhibited reduced BPGM levels in the syncytiotrophoblast layer compared to placentae from healthy uncomplicated pregnancies. Levels of 2,3 BPG, the product of BPGM, were lower in cord serum of human FGR placentae compared to control. Polar expression of BPGM was found in both human and mouse placentae syncytiotrophoblast, with higher expression facing the maternal circulation. Moreover, in the murine SpA TGCs expression of BPGM was concentrated exclusively in the apical cell side, in direct proximity to the maternal circulation.Conclusions:This study suggests a possible involvement of placental BPGM in maternal-fetal oxygen transfer, and in the pathophysiology of FGR.Funding:This work was supported by the Weizmann Krenter Foundation and the Weizmann – Ichilov (Tel Aviv Sourasky Medical Center) Collaborative Grant in Biomedical Research, by the Minerva Foundation, by the ISF KillCorona grant 3777/19.

Published: February 2024

Aims: Weeding operation is one of the most laborious and time-consuming operation in agriculture. Weeds basically an unwanted plant which competes with crop for light, moisture, and nutrient along with lowering the overall yield. Mechanical weed control methods are preferred among all weeding methods due to many reasons such as timeliness, safety, drudgery and cost effective.
Study Area and Duration: The experiment was conducted in the farmer’s field of Abhayapuri, Bongaigaon, Assam in the year 2021 to 2023.
Methodology: This study employed a 5.75 hp self-propelled diesel engine with three blade sets—rotary, non-rotary, and a combination of both, designed for weeding in vegetable fields with row spacing up to 75 cm. One-way ANOVA analysis compared group means for statistical significance.
Results: Results showed that the field efficiency (90%), fuel consumption (7.7 l/ha), cost of operation (Rs 1217.7 per ha) and plant damage factor (0.01%) was better for rotary blade than non-rotary and combined blade. Whereas effective field capacity (0.07 ha/h), performance index (155.7) and man-hour/ha (14.3) was better for non-rotary blade and the parameters such as depth (4.4 cm) and weeding efficiency (94.2%) was better for combined blade mechanism. From the one-way ANOVA analysis, it showed that blade mechanism showed significant difference on parameters like weeding efficiency, field efficiency, fuel consumption, effective field capacity, cost of operation, man-h/ha and performance index at p<0.05 and non-significant for depth and plant damage factor at P<0.05.
Conclusion: Study concluded that for intra-row weeding operation, rotary blade along with non-rotary blade was suitable economically whereas combined blade was suitable for weeding performance only besides high cost.
