Pengenalan Pose Tangan Menggunakan HuMoment

Computer vision yang didasarkan pada pengenalan bentuk memiliki banyak potensi dalam interaksi manusia dan komputer. Pose tangan dapat dijadikan simbol interaksi manusia dengan komputer seperti halnya pada penggunaan berbagai pose tangan pada bahasa isyarat. Berbagai pose tangan dapat digunakan untuk menggantikan fungsi mouse, untuk mengendalikan robot, dan sebagainya. Penelitian ini difokuskan pada pembangunan sistem pengenalan pose tangan menggunakan HuMoment. Proses pengenalan pose tangan dimulai dengan melakukan segmentasi citra masukan untuk menghasilkan citra ROI (Region of Interest) yaitu area telapak tangan. Selanjutnya dilakukan proses deteksi tepi. Kemudian dilakukan ekstraksi nilai HuMoment. Nilai HuMoment dikuantisasikan ke dalam bukukode yang dihasilkan dari proses pelatihan menggunakan K-Means. Proses kuantisasi dilakukan dengan menghitung nilai Euclidean Distance terkecil antara nilai HuMomment citra masukan dan bukukode. Berdasarkan hasil penelitian, nilai akurasi sistem dalam mengenali pose tangan adalah 88.57%

Model Perlindungan Konsumen Batik Dan Penjaga Keberlangsungan Batik Asli Kota Pekalongan Melalui Aplikasi E-label Batik Yang Memanfaatkan Teknologi Augmented Reality Berbasis Cloud Computing

Ketidaktahuan serta kesalahan persepsi konsumen yang menganggap produk printing tekstil bermotif batik adalah produk batik asli, merupakan salah satu faktor pengganggu eksistensi batik asli di kota Pekalongan. Faktor tersebut, tidak hanya menyebabkan kerugian untuk produsen batik yang mengalami penuruan omset penjualan karena konsumen cenderung membeli produk printing tekstil bermotif batik (dihasilkan oleh pabrik tekstil) yang harganya jauh lebih murah, tetapi juga membuat konsumen menjadi rentan dari berbagai upaya penipuan oknum produsen batik yang tidak jujur. Hal tersebut menjadi perhatian bagi pemerintah kota Pekalongan dan melalui Peraturan Daerah Nomor 6 Tahun 2014, semua produk batik asli yang dibuat dan dijual di kota Pekalongan diwajibkan menempelkan label “Batik Pekalongan”. Label tersebut menjadi penanda resmi yang membantu konsumen dalam membedakan jenis produk batik yang dibelinya (tulis/cap/kombinasi) serta membedakannya dengan produk printing tekstil bermotif batik. Data yang terkumpul dari berbagai sumber akan dianalisis, kemudian dengan memanfaatkan teknologi augmented reality berbasis cloud computing akan dibangun aplikasi e-label batik. Aplikasi tersebut, tidak hanya mampu mencetak label “Batik Pekalongan” saja, namun juga mampu memudahkan pemerintah kota Pekalongan dan ASEPHI kota Pekalongan untuk melakukan pengawasan dan kontrol pemakaian label tersebut, sehingga keberadaannya akan memberikan kepercayaan tinggi dan melindungi hak-hak konsumen batik

INCREASED GROWTH AND YIELD OF LOCAL SUMATRAN RED CHILI VARIETIES BY GIVING HUMIC ACID UNDER LIMITED SOIL WATER AVAILIBILITY

Research aimed at increasing the production and productivity of various Local Sumatran red chili varieties under limited soil water availability using humic acid was carried out from May to October 2022, at the Teaching and Research Farm, Faculty of Agriculture, Jambi University (35 m above sea level). The research used a Randomized Block Design with a factorial pattern and three replications. The first factor is the dose of humic acid: 0 kgha-1; 5 kgha-1; and 10 kgha-1, and the second factor is Local Sumatran red chili varieties: Vitra; Loker Telun Berasap; and Awe Aceh. The research results showed that various red chili varieties gave the same response to the application of humic acid under limited soil water availability of 75% FC. Humic acid can increase the growth and yield of red chilies, and a dose of 10 kgha-1 provides the best growth and yields for red chilies. The Loker variety provides better plant height, number of branches, crown diameter, and fruit number than other varieties, but produces the lowest fruit weight. Meanwhile, the Vitra and Awe varieties, although their growth is relatively not as good as Loker, are capable of producing high fruit weights. The Loker variety, which is a red chili variety from the Kerinci highlands, has not been able to adapt well to the lowlands of Jambi. One effort to increase the ability of the Loker variety to produce better quality fruit is to combine humic acid with liquid fertilizer during fruit enlargement

Democratization and the Diffusion of Shari'a Law: Comparative Insights from Indonesia

The democratization of politics has been accompanied by a rise of Islamic laws in many Muslim-majority countries. Despite a growing interest in the phenomenon, the Islamization of politics in democratizing Muslim-majority countries is rarely understood as a process that unfolds across space and time. Based on an original dataset established during years of field research in Indonesia, this article analyzes the spread of shari’a regulations across the world’s largest Muslim-majority democracy since 1998. The article shows that shari’a regulations in Indonesia diffused unevenly across space and time. Explanations put forward in the literature on the diffusion of morality policies in other countries such as geographic proximity, institutions, intergovernmental relations and economic conditions did not explain the patterns in the diffusion of shari’a regulations in Indonesia well. Instead, shari’a regulations in Indonesia were most likely to spread across jurisdictions where local Islamist groups situated outside the party system had an established presence. In short, the Islamization of politics was highly contingent on local conditions. Future research will need to pay more attention to local Islamist activists and networks situated outside formal politics as potential causes for the diffusion of shari’a law in democratizing Muslim-majority countries

Morphology and phylogenetic relationships of five chili cultivars from Sumatra, Indonesia

Chili is an important horticultural crop which contribute substantially to the national income of Indonesia. As the demand of chili continues to increase, exploration of local superior varieties from various regions in Indonesia become one of priorities in the development of new chili cultivars. This research aimed to study morphology and phylogenetic relationship of chili cultivars from different parts of Sumatra, Indonesia. The study was conducted at the Teaching and Research Farm, Faculty of Agriculture University of Jambi, from May through to November 2021. Five chili cultivars (Loker Telun Berasap and Ahang Adro from Kerinci Regency, Jambi Province, Kopay from West Sumatra Province, and Awe and Udeng from Nanggroe Aceh Darussalam Province) were evaluated for their morphological traits and phylogenetic relationship. The trial was arranged in a randomized block design with 5 replicates, and each replicate consisted of 5 plots. There were 25 plants in each plot, of which 8 plants were taken as samples. Qualitative and quantitative traits were observed on leaves, flowers, fruits, seeds, and stem. Data were analyzed using cluster analysis method using Minitab® (Version 18) application to evaluate phylogenetic relationship among cultivars based on similarity of morphological traits. Results showed that the five chili cultivars showed variations in qualitative and quantitative traits. In addition, there are also variations in their growth and morphology. Based on cluster analysis dendrogram, it was found that Loker Telun Berasap and Ahang Adro showed differences in morphological traits from the other three cultivars. These two cultivars are, therefore, proposed to be listed for cultivar release as part of germplasm conservation program to protect local superior chili cultivar of Jambi Province

COMBINATION OF BAP AND TDZ IN INDUCING THE GROWTH OF BANANA SHOOTING EXPLANT CV. BARANGAN IN VITRO

Barangan banana (Musa acuminata L.) is one of the superior types of banana in the West Tanjung Jabung district, Jambi Province - Indonesia. Barangan bananas are very popular with the public and have high economic value. The problem faced in conventional cultivation and development of Barangan bananas is that it is difficult to obtain quality banana seeds in large and uniform quantities, so to overcome this we need alternative technology for propagating banana seeds through modern techniques such as plant tissue culture techniques. The advantage of this technique is that it is able to produce plant seeds en masse uniformly and in a relatively short time. In addition, the resulting progeny is also conditioned to be free from pests and diseases, especially diseases caused by bacteria and fungi

NITRATE REDUCTASE ENZYME ACTIVITY AND ITS CORRELATION WITH SOYBEANS YIELD IN SATURATED SOIL CULTURE AND WATERING CULTIVATION IN TIDAL LAND

This study aimed to determine the Activity of Nitrate Reductase (ANR) of soybean in Saturated Soil Culture (SSC) and Watering Cultivation (WC) in tidal land and its correlation with aspects of soybean yield of the Anjasmoro cultivar. Treatment applications were arranged in a randomized block design (RBD) with three replications. The height of standing water in the trench in the Saturated Soil Culture system (SSC) as a treatment in this study was 15 cm, 20 cm, and 25 cm from the soil surface. WC actors were selected from 3 farmer groups. Soybean seeds were planted in experimental plots measuring 3 m x 2 m with a spacing of 30 cm x 20 cm, according to the spacing used by farmers. SP36, KCl, and Urea fertilizers were given as basic fertilizers at the recommended dosage. Observation variables included: ANR, number of filled pods/plant, dry seed weight/100 seeds, and dry seed weight/plant. The results showed that the height of standing water in the ditch in SSC affected the ANR and soybean yield. There was no difference in ANR for the height of the water in the ditch 15 cm and 20 cm from the soil surface, 12.76 mol NO2, respectively g-1hour-1 and 13.43 mol NO2. g-1. hour-1. The lowest ANR was obtained at the treatment level with the height of the puddle in the ditch 25 cm from the soil surface, namely 11.52 mol NO2. g-1.h-1, but still higher than the ANR in WC. There was no difference in the number of filled pods/plant, dry seed weight/100 seeds, and dry seed weight/plant between the height of standing water in the 15 cm trench and 20 cm from the soil surface

NITROGEN METABOLISM OF SOYBEAN AT SATURATED SOIL CULTURE AND WATERING CULTIVATION OF FARMER’S SYSTEM IN CONDITIONS OF TIDAL LAND

This research aimed to study the effect of the water-saturated cultivation system of Tidal land on nitrogen metabolism in soybean. Treatment was growing plants on benches, at the different water levels of trenches-which were 15 cm, 20 cm, and 25 cm from the soil surface- arranged in a randomized block design with three replications. The results showed that the height of standing water in the trench affected the soil water, leaf proline, and N content. The water level of 15 cm had a higher soil water potential (-0.48 MPa), the proline content of 1.52 mol/g fresh leaf weight, and the N content of leaves was 2.6% than those of 20 cm and 25 cm. The lowest N content and leaf chlorophyll content were obtained at a height of water level of 25 cm, namely 1.79% leaf fresh weight and 1.74% leaf fresh weight, respectively, but, higher proline content was found at 2.47µmol/g fresh leaf weight. Thus, both the water level of the bench of 15 cm and 20 cm had better nitrogen metabolism. Plants grown at the benches of 25 cm can still withstand low soil water content, proven by their highest leaf proline content. The increase in proline value in soybeans under stress conditions was caused by de novo synthesis, not due to protein degradation. The mechanism of nitrogen metabolism in soybean (C3) under mild stress conditions is postulated to be the same as nitrogen metabolism in corn (C4)

COMBINING BIOCHAR AND LIQUID ORGANIC FERTILIZER FOR IMPROVEMENT OF SHALLOT GROWTH AND YIELD

This study aims to examine the response of shallots to applying biochar and liquid organic fertilizer combination, and to obtain the combination that gives the highest growth and yield of shallots. The research design used was a randomized block design (RBD) with one factor, namely the combination of biochar dosage and liquid organic fertilizer (LOF) concentration consisting of 0 tonha-1 biochar + 0 mL-1 LOF; 0 tons ha-1 biochar + 7.5 ml L-1 LOF;0tonha-1 biochar + 15 mLL-1 LOF; 10 tonha-1 biochar + 0 mLL-1 LOF; 10 tonha-1 biochar + 7.5 mLL-1 LOF; 10 tonha-1 biochar + 15 mLL-1 LOF; 20 tonha-1 biochar + 0 mLL-1 LOF; 20 tonha-1 biochar + 7.5 mLL-1 LOF; 20 tonha-1 biochar + 15 mLL-1 LOF. Each treatment was repeated 3 times. The results showed that the combination of biochar and liquid organic fertilizer increased the growth and yield of shallots. The best combination was obtained at 20 tonha-1 biochar + 7.5 mLL-1 LOF. The productivity of shallots in the form of dry tuber weight from this study (6.8 tonha-1) is still low when compared to the national average (9 tonha-1), and the yield potential of shallots of the Brebes variety (9.9 tonha-1). When compared to shallots that were not given biochar and not given LOF, the yield of shallots in the form of tuber dry weight increased by 139.86% by administering a combination of biochar 20 tonha-1 + 7.5 mLL-1 LOF
