Kelompok Tani Pusaka 1 Desa Babakan Kabupaten Purwakarta merupakan salah satu kelompok tani penerima bantuan P2L sejak tahun 2020 tetapi masih terdapat beberapa kendala dalam pelaksanaan program P2L antara lain terkait pengetahuan anggota dalam kegiatan budidaya di pekarangan rumah. Upaya untuk meningkatkan pengetahuan petani adalah dengan penyuluhan oleh BPP Wanayasa. Penelitian ini bertujuan mengetahui respon petani program Pekarangan Pangan Lestari (P2L) terhadap kegiatan penyuluhan yang dilakukan oleh BPP Wanayasa dengan menilai pengetahuan, sikap dan keterampilan anggota kelompok tani. Metode penelitian adalah survey dengan menggunakan data kuantitatif didukung data kualitatif. Responden dipilih secara simple random sampling sebanyak 15 petani. Objek penelitian dipilih secara purposive yaitu kelompok tani Pusaka 1 Desa Babakan karena mendapat bantuan P2L. Hasil penelitian menunjukkan bahwa pengetahuan petani setelah dilakukan penyuluhan berupa pembuatan pupuk kompos mengalami peningkatan menjadi 73,3%, cara pengendalian hama menjadi 100%, mengetahui tanaman yang memiliki nilai ekonomis tinggi menjadi 93,3% dan pengelolaan tanah yang baik menjadi 86,7%. Sikap petani terhadap kegiatan penyuluhan memberikan respon sangat baik yaitu 80%. Keterampilan petani dalam aspek pemasaran hasil panen dan nilai tambah hasil panen tidak terlalu banyak perubahan sebelum dan setelah diadakan penyuluhan sehingga disimpulkan bahwa petani memberikan respon yang sangat baik terhadap penyuluhan dan terjadi peningkatan pengetahuan. Akan tetapi penyuluhan belum sepenuhnya merubah keterampilan anggota kelopok tani Pusaka 1 program Pekarangan Pangan Lestari (P2L).

Background: Radon (222Rn), a naturally occurring radioactive gas, dissolves in water, and it can be found in elevated concentrations in public water supplies when water originates from ground sources in areas rich in uranium. An area of great interest for measuring radon-in-water is the Migdonia basin in Northern Greece due to its geological background and because all of its villages are supplied with water from boreholes.
Objectives: The main aim of this paper was to study the time variation of radon in tap water activity concentration in nine villages of the Migdonia basin supplied with water from boreholes and to determine factors that may affect it. Radon in water correlation between the source (borehole) and the consumption point (tap) was studied for some villages. Also, the correlation among radon, gross alpha, beta, uranium (238U), and radium (226Ra) activity concentration in water was studied.
Design and methods: Water samples were collected and measured for their radon activity concentration from 66 villages in the Migdonia basin in order to find places with relatively high radon concentrations. The time variation of radon-in-water was studied for villages that showed relatively high radon concentrations for 3–4 years (2018–2022). All samples were measured for their 222Rn activity concentration using gamma-ray spectrometry. Water samples were also analyzed for their gross alpha, beta, and uranium isotopes activity concentration.
Results and conclusions: Average radon in tap water activity concentrations measured in the area ranged from background concentrations to 185 Bq L-1. The corresponding annual effective doses from waterborne radon inhalation using both UNSCEAR and ICRP dose conversion factors ranged from 0.01 to 0.466 mSv y-1 and from 0.02 to 0.868 mSv y-1, respectively, while radon ingestion annual effective doses varied from 0.007 to 0.324 mSv y-1. Time variation of radon activity concentration in tap water for villages supplied from one borehole or a constant number of boreholes showed relatively low standard deviations (<24%) at a coverage factor of k = 1. Those deviations are probably caused by the time variation of boreholes’ radon concentration and water demand changes. A significant decline in radon concentration from the source (borehole) to the consumption point (tap water) was observed. Therefore, sampling should be performed at the consumption point. However, knowing the supplying borehole concentration is useful as it determines the potential for radon in drinking water. No apparent correlation was found among radon, gross alpha, beta, uranium, and radium concentrations in water. However, in some cases, remedial actions (withdrawal of boreholes) for uranium concentration also decreased radon concentration.

Astract
We fabricated B-doped p-BaSi2/n-Si heterojunction solar cells by molecular beam epitaxy, and performed post-annealing at 1000 °C in an Ar atmosphere for various annealing durations (t
a) in the range 15–300 s. At t
a = 15 s, the conversion efficiency (η) under AM 1.5 G illumination was degraded unexpectedly from η = 1.96% for the as-grown sample to η = 0.8%. At t
a ≥ 30 s, improvement of the open-circuit voltage (V
OC) was obtained. V
OC was increased from 0.28 V for the as-grown sample to 0.45 V at t
a = 30 s, and the η reached 5.1%. Deep level transient spectroscopy measurement indicated the presence of hole traps coming from point defects near the BaSi2/Si interface. The surface morphology remained almost unchanged at t
a ≤ 60 s. However, part of the surface peeled off at t
a ≥ 120 s when we separated the attached samples from each other.

Abstract
The formation of students' character is doubtful for their success in learning during the current pandemic. Learning from home makes teachers limited in carrying out learning and building student character. One positive step is the School Literacy Movement. The success of this literacy activity will certainly succeed with the cooperation of teachers and parents to cultivate and provide literacy activities. This training focuses on the skills of teachers to digitize and use applications to provide literacy materials that can stimulate the formation of student character. The methods of implementing this training are introduction, training, practice, and simulation. The objects of this activity are the teachers of SD Negeri 2 Bayongbong and parents of students. This training begins with equalizing perceptions, presentation of materials, and practices in the form of digitalization simulations until they are distributed to students. The evaluation of this activity shows that this training can make it easier for teachers to prepare literacy materials and teaching materials so that they can succeed in the formation of student character. It is hoped that the teachers will succeed in GLS so that they can shape the character of students.

Abstract
The use of good and correct Indonesian is one of the ideals of the nation as stated in the law. This is used as an effort to strengthen government administration at the central to regional levels. Efforts to strengthen the Indonesian language in local government administration are the use of good and correct language in correspondence. They do not know the use of official letter language in accordance with linguistic rules. This is evident from the results of the analysis of errors in correspondence made by the Mekarjaya village apparatus in the Bayongbong sub-district, Garut district. The results of the analysis show that there are many errors in the use of letters and editorial errors, including the use of diction, spelling, effective sentences, titi prey, and letterhead. With these problems, training in writing correspondence in good and correct Indonesian was carried out for the Mekarjaya village apparatus, Bayongbong district, Garut district. The results of the training showed an increase in knowledge and practice in making correspondence according to the standard rules for writing official letters.

Die Presskraft ist in Umformprozessen eine zentrale Messgröße für die Prozessüberwachung und wird meist durch Federkörper im Krafthauptschluss oberhalb des Stempels oder unterhalb der Matrize erfasst. Als Alternative dazu wird in diesem Beitrag der Einsatz von Kraftmessschrauben (PiezoBolts) zur Dehnungsmessung im Armierungsring bei einem beispielhaften Kaltmassivumformverfahren untersucht. Es werden zwei Einbausituationen der Kraftmessschraube experimentell und simulativ betrachtet sowie die ermittelten zeitlichen Dehnungsverläufe gegenübergestellt.

Forming load is one of the most decisive parameters in metal forming and is usually measured by using strain gauges, applied on pressure plates located in the main load path above the punch or beneath the die. An alternative investigated here is to apply load measuring bolts (PiezoBolts) for strain measurement in the die compression ring of an exemplary cold forging process. This paper investigates two different mounting positions fpr the PiezoBolt and compares strain profiles gained from experiment and simulation.

Authors: Wu Yutian , Leng Yuchen , Groche Peter 
Published: November 2022

Verschleißfestigkeitskennlinien (VFK) helfen bei der Abschätzung der Werkzeugstandzeiten für neue Umformprozesse. Sie erlauben die Vorhersage der Lebensdauer unter dem speziellen Lastniveau eines geplanten Prozesses anhand aufwandsarm zu bestimmender Verschleißdaten bei hohen Lasten. Dieser Beitrag stell das Verfahren zur Standzeitabschätzung sowohl für beschichtete als auch für unbeschichtete Werkzeuge vor. Als Modellversuch dient der Streifenziehversuch. Die VFK können nicht nur zur quantitativen Abschätzung der Werkzeuglebensdauer, sondern auch zur Analyse des Verschleißverhaltens verwendet werden.

Wear resistance curves (WRC) are a useful tool for tool life estimation in new forming processes. They allow the prediction of tool life under the specific load level of a planned process based on low-effort wear data determination at high loads. This paper presents a method for estimating tool life for coated and uncoated tools. The strip drawing test is used as a model test. The characteristic curves can be used not only for quantitative estimation of tool life but also for analysis of wear behavior.

Die manuelle Montage zählt durch mangelnde Schnittstellen zur automatisierten Datenerfassung häufig zu den blinden Flecken für Industrie 4.0 und den dadurch möglichen Potenzialen zur Produktivitätssteigerung. Echtzeitlokalisierung bietet hier nicht nur die Möglichkeit Verschwendung durch Laufwege zu analysieren, sondern lässt sich auch für geofencing-basierte Produktionssteuerung nutzen. Der hier beschriebene systematische Vergleich zeigt welche Technologie sich hierfür am besten eignet.

Due to a lack of interfaces for automated data acquisition, manual assembly is often among the blind spots for Industry 4.0 and the hoped-for potential for increasing productivity. Here, real-time localization not only offers the possibility of analyzing waste caused by movement, but can also be used for geofencing-based production control. The systematic comparison described here shows which technology is best suited for this purpose.
On Internal and External Alignment of Dust Grains in Protostellar Environments

Abstract
Multiwavelength observations toward protostars reveal complex properties of dust polarization, which are challenging to interpret. Here we study the physical processes inducing the alignment of the grain axis of the maximum inertia moment with the angular momentum (
J
; i.e., internal alignment) and of
J
with the magnetic field (i.e., external alignment) of very large grains (VLGs; of radius a > 10 μm) using the alignment framework based on radiative torques (RATs) and mechanical torques (METs). We derive analytical formulae for critical sizes of grain alignment, assuming grains aligned at low-J and high-J attractors by RATs (METs). For protostellar cores, we find that super-Barnett relaxation induces efficient internal alignment for VLGs with large iron inclusions, but inelastic relaxation is efficient for VLGs regardless of composition aligned at high-J attractors by RATs (METs). For external alignment, VLGs with iron inclusions aligned at high-J attractors have magnetic alignment by RATs (B-RAT) or METs (B-MET), enabling dust polarization as a reliable tracer of magnetic fields in dense regions. Still, grains at low-J attractors or without iron inclusions have alignment with
J
along the radiation direction (k-RAT) or gas flow (v-MET). For protostellar disks, we find that super-Barnett relaxation is efficient for grains with large iron inclusions in the outer disk thanks to spin-up by METs, but inelastic relaxation is inefficient. VLGs aligned at low-J attractors can have k-RAT (v-MET) alignment, but grains aligned at high-J attractors likely exhibit B-RAT (B-MET) alignment. We also find that grain alignment by METs is more important than that by RATs in protostellar disks.
